└───────────────────────┘

You weren't sure how long you'd been there; a few weeks?

You think so. Four? Four sounds right. You could ask Albert for the date, but he'd probably lie.

You knew it was... well, was it June or August? It was... summer, you thought. Summer sounded right, and you thought you remembered the date being the 23rd of... you decided it was August. So was it now September? Had it really been years?

How had you gotten so out of sorts? It was only four weeks. Maybe it was the lack of any sort of communication. Just books and your thoughts. Maybe it was the hissing vents every half hour—carbon monoxide? No, you noticed the sensors the first day. Plus, Albert wouldn't be so uncaring.

Albert brought food at mealtimes and left to do work, coming back only at odd hours of the night to go to sleep in his bed. You elected to sleep on the couch instead. Maybe that was why he wasn't giving you anything nice.

As an experiment, you waited until Albert came by with lunch. "Hey," you greeted, anxiety coursing through your veins. Usually you ignored him. "Could you... stay for lunch?"

You pushed down the relief that overtook you when Albert gazed at you with satisfaction. That was bad, you hated him, you should hate him.

"Of course, darling. Something change your mind?" he asked smoothly as he strolled too close for comfort and sat down on the sofa with you. He took his gloves off to give you a half hug. Well, you suspected it was more the desire to feel your warmth through your shirt.

"Just some questions," you murmured as you opened the lunch and began to eat. "How long have I been here? And what's the date?" You tried, but assumed he'd give you the wrong information.

"You've been here for nine days. I brought you here July 25th, it's now August 3rd. I can show you a digital calendar, if you don't believe me," he answered truthfully.

What? Nine days? It felt like months. But Wesker was being truthful... how had you mixed up nine days with four weeks?

"...oh. No, I believe you. Uh, will I be allowed to go with you when you work on things? Just to get out of this place," you asked hopefully. You felt a twinge of disappointment when Albert laughed.

Albert took his sunglasses off to stare into your eyes. "I'n terribly sorry, sweetheart. You're just too much of a liability. You don't trust me, you want to escape, and you fought tooth and nail every time you saw me until I put that shock collar on... but now you want to be let into top-secret bioweapons discussions?" He cupped your chin patronizingly.

"...ah. I guess I see why l'd be not allowed. Well, could you at least take me out of here some time? I'm getting cabin fever," you bargained awkwardly. You hated getting reminded of that thing around your neck.

"I'll tell you what. If you stop avoiding me altogether, I'll take you out and let you see my office," Albert promised, thumbs tracing your cheekbones. "Does that sound good? When I'm working in there, I can bring you with me and you can amuse yourself however you like."

You nodded quietly and tried to think of what your next move should be. In a stiff fashion, you set your head upon Albert's shoulders.

You heard and felt Albert chuckle, then felt his hands combing through your hair. "I can see what your plan is," he continued, using your name for extra emphasis, "and it won't work. But I do enjoy you becoming clingy once more. Perhaps I'll do what you want, give you personal freedoms for your obedience. However, I'd much rather you learn your place and stay in it of your own volition. Don't worry, dear, I'll hold you through every identity crisis you'll have."

You wanted to push him off; you were sure he could tell you were annoyed with him calling you out, but you didn't move. In fact, you doubled down and placed your hand on top of his. You felt Albert grin. You ignored it and finished your food. Maybe he was right. Maybe it was just easier to... accept him. Chris would come for you, but was it worth it? Returning to the BSAA, fighting battles with people who would never give up, leaving Albert again.

...

No. No! You wouldn't let Albert—no, Wesker, you wouldn't give him the pleasure of familiarity—win. He'd kidnapped you, was isolating you, and probably wouldn't stop manipulating you until you were working alongside him. You resolved then: you'd fight even with the shock collar on. The pain was worth hurting Wesker. You hoped he still loved you, so seeing you in pain hurt him, too.

"Now, now, pet. The silent treatment? Don't you have anything to say to me?" Another beat, and Wesker spoke again. "Well, I do have things to get back to. You play nice, be a good dog and—"

When Wesker stood up, straightening his already-perfect clothes like the megalomaniac he was, you stood up with him and punched him square in the jaw.

You'd half expected Wesker to dodge it with the superhuman accuracy he was known for, but he didn't and you watched with sick pleasure as blood soaked spit dribbled down his lips.

He pressed a hand to his jaw, silently working the pain out of it, then looked at you with a disturbing mixture of excitement and anger.

"That's better. Well, I suppose not for you, but I was afraid I'd snuffed your fire. Hm. Still nothing to say?"

With that, you tackled him.

You pounced on him, bringing him to the floor with ease. He was going easy on you, and you knew it. That only made you angrier.

"I'm not your fucking dog; you're more dog than I am," You growled as you grabbed his throat and straddled his waist. When he grinned at you and canted his hips up, you slapped him across the face. "You're into that? Really?" You snapped, chest heaving angrily.

"The BSAA is gonna find me, Wesker. And I'm going to go back to them."

Uh oh.

That sentence seemed to sour his mood, and suddenly you felt the collar around your throat power on. "Wait—ah, stop!" You protested as Wesker pushed you off almost clinically and moved the coffee table so you had space to seize. All the while, you knew what was coming but scrambled up to beg him to stop.

He put it immediately to 5 mA, but you knew it was only the beginning. The shock hurt like a static shock but all across your body and inescapable. It was going to get worse. "Fuck—I'm sorry," you gritted out, sinking back to the floor.

15 mA now, you felt like you were slowly losing muscle control to near constant unpredictable twitches; you couldn't force down the screams. "Wesker, please!" You choked out, scrabbling desperately at the collar. He stood over you, glaring through his sunglasses, and turned it up.

You counted seven clicks, meaning you were at 50 mA, higher than he'd gone before. Your muscles all tensed into one other before returning to violent spasms, hands clenching around the collar and only hurting more. But he turned it up five more times.

75 mA. Fire flooded through your veins and you felt like passing out from the agony but you couldn't because the shocks kept you awake. You thought you were going to die. Black spots bled through your vision and all you could think of was, if I do die, at least Albert didn't win. Suddenly, the electricity was off, but you were still thrashing and realized you were crying.

"Shh, shh, shh. It's over, darling. You're okay now," Wesker cooed, scooping you up and seeing you down on the couch. "You see it now? You should never mention them again. You should never attack me again... unless I ask you to. And you should never say you'll leave again."

After a moment, Wesker put on a sweet voice. "You behave, and I won't have to hurt you. Your heart is beating just a little fast, I'll stay beside you to make sure the electricity didn't cause any adverse effects. You've got to stop forcing me to do this."

"Fuck you," you weakly sobbed, your muscles aching in pain. Wesker tutted and crouched beside you, cupping your jaw and tilting your head up.

"You'll see soon. You don't yet, but I expected that. Hm, your next dose is soon, I'll be back in a moment," Wesker coldly noticed, dropping your head abruptly and leaving the room. Once the door closed, you heard a dull hissing from the vents above and then you felt yourself floating away. The last thing you heard in the minutes of your waning consciousness was the door opening and Wesker's dark chuckle.

──────────────────────

You slept from lunch to early in the morning and woke up in a bed. Wesker's bed, you knew immediately, since not only did you solely sleep on the couch but it smelled just like him, like you were wrapped up in his trench coat.

Also, Wesker himself was holding you like a body pillow. Maybe that was the first sign. His face was buried in the crook of your neck, he had one arm under you and one arm over you like a hug, and his legs caged you in, to top it off.

You tried to wriggle away, but with his enhanced strength you doubted you'd be able to. You glared over at him and felt a twinge in your heart; the way he slept was the exact same as when you were dating. He wore a black long sleeve and sweatpants, plus socks, but his hands were bare, a rarity now what with his preference for leather gloves. You realized with no small amount of disgust that you were changed into pajamas that matched, underwear included.

You managed to get halfway out of his grip before he woke up and scowled. "Lay back down. I'm still tired, and it's only 5:00," he commanded.

"I'm not sleeping in the same bed as you," you replied angrily, but he reached into the headboard and sent a shock of 2 mA in your body to serve as a warning. "Hey! Fucking—fine, Wesker, I'll lay down," you grumbled as you surrendered to his cuddling.

"Albert," Wesker corrected. "I'm rather tired of hearing it from your lips—my surname, that is. Not nearly intimate enough. Every time you call me Wesker from this point forward, you'll get a shock. 10 mA sounds just fine."

"What? Wes—Albert, you just said it was 5:00AM. Isn't that a bit early to threaten me with electrocution?" You protested.

"Would you like to make it 15?" He replied coldly. "Stop moving. I had a perfect sleeping position."

It wasn't until 7:00, maybe 7:30 that Albert got up. That Wesker got up. You'd have to call him by his first name aloud, but you were still able to call him Wesker in your head. For now.

"Good morning," Wesker hummed, finally taking his arms off of you. A foolish part of you missed his warmth. "I have a surprise. I'd like to make up for yesterday's... punishment. Come to the kitchen, darling—up you go, good job. I can give you some morphine for your muscles, they must be in just agony."

You limped to the kitchen table, set for two, and didn't realize just how in pain you were until you felt a sudden lack of it and glanced over to see Wesker beside you with a needle in your neck. "Oh," you murmured in surprise.

"Excellent. You seem to not be bothered by needles," Wesker noted, to which you replied, "No, I am; I'm just in enough pain that I didn't notice it."

Wesker gave a quiet 'Ah' and turned around. He opened the fridge and you were surprised to see actual food inside it. You curiously stood and opened the pantry, then hummed in approval when you saw food in it, too. Plus, your favorite snacks, which you were surprised and a little creeped out by, since you'd only learned of some of them in recent months.

You sat back down, deciding to help yourself to whatever food you could get when Wesker made his breakfast and left for work. Instead, he made two servings of breakfast and placed the plate in front of you before sitting across from you. You furrowed your brow. "You're sitting to eat? Usually, you don't have time for that," you questioned.

"I took a day off. After yesterday, I'm sure you need help getting around and would like some company."

You bit back a bitter "Not your company," and nodded imperceptibly.

A day with Wesker. Seems fun.

You know how cat’s rub up on you to make you smell like them and ‘claim’ you would pilot au N do that same with Uzi?

In the later stages of the au, he would! He gets more comfortable with physical touch with her after a while, as we see start to happen at the tail end of Sense of Home, so pretty naturally she starts having a hint of Eu De Disassembly Drone- which is only a distinct scent due to the partially biological nature of DDs, as a fun fact. Organics tend to have a smell about them, even the highly sterilized and purposefully-grown components of a DD

Of course she has no idea she has the Stank since she, like most non-specific-specialist Worker Drones, doesn't have olfactory sensors. (though she does have an air quality sensor... but it doesn't work like an actual sense of smell. It's more like a carbon monoxide detector- the sensory feedback is completely different from actual scent)

St. George, Utah

September 2017

Nate sat on the uncomfortable auto-shop waiting room chair, mindlessly scrolling through his social media feed without really reading it. Yesterday, after he had composed himself, he had taken all of his finds to his van and drove to Henderson. When he texted the news to his co-workers, he discovered that they were actually hourly workers who did get overtime, and they wanted to make up the hours they missed with the short work day on Friday. He helped Barry and Hudson install the carbon monoxide and carbon dioxide sensors in the building. Hudson’s familiarity with the system even let him set up an automated alarm system that flashed the show lights red when one of the alarms went off. Nate worried that guests would just think it was part of the show, but at least it was impossible to ignore.

Faith managed to glue Freddy’s skin back to its skull, although she had to tear out the added ears for it to fit. For it and Bonnie, they set them up on stands to display both the head and body piece. The original haunted house had stands that used to hold costumes. They were being kept in storage on site, and the manager on duty then was able to let them in. From Nate’s brief interactions with the park employees, he got the sense that they didn’t like the Frights staff, probably some combination not liking having another company’s employees invading their domain and (at least Nate hoped) ethical objection to the attraction. For Chica, Duane had the idea to set one of their floor strobe lights to always on and use it to turn the head into a lamp.

Without Foxy’s original casing, Nate wasn’t sure what they could do with its skin, but Faith got really excited with the idea of using a bowl and cosplay foam to recreate the skull, and then mounting it on the wall as a lamp, similar to Chica. Nate’s first thought was to tell her she didn’t have to go to all the effort, but her enthusiasm was infectious. Around other people who didn’t have any ulterior motives, it was even harder to remember not to give Fazbear Entertainment his best. So, he simply told her to make sure she recorded her hours and not neglect her schoolwork.

Nate was also vaguely worried about the strange clear residue that covered his co-workers’ hands after handling the animatronic heads. He had no idea what it could be, although all the heads were quite filthy. He knew telling them all to wear gloves wouldn’t be listened to, so he just told them to always wash their hands in the park bathroom after working with the heads. Once they were all set up, hopefully no one would have any reason to touch them. Interestingly, none of it got on Nate’s insulating gloves.

Today began with Nate bolting awake, albeit at a reasonable hour, in his usual motel in Henderson realizing that he still had a handful of files from the archive to catalog. He was suddenly very worried that since he had explored the Hurricane location, Mr. Edwards would tell him to focus entirely on managing the attraction. Even though he wasn’t deluding himself about finding some big clue, he was still going to do what he told Miranda and start publishing his research when he got back. He already had ideas many of the documents he had copied would help him with, and the folders he still needed to catalog could still hold important building blocks. So, he texted Ashleigh about getting access to the office so he could work on Sunday, phrasing it like he was just so productive and wanted to finish the project he was originally hired so he could focus entirely on managing. She texted back to go ahead and that there was a spare key hidden in one of the potted plants in the hallway near the office.

That was the plan, but Nate’s van died just inside the Utah border. Thankfully he was a Triple A member and was able to get towed to an auto shop in the western outskirts of St. George. He had refurbished the van over the years, but it was with the help of a friend who was really into cars. Especially without equipment, he was completely dependent on this place. As he sat there, he desperately tried not to start attempting to estimate how many excess miles he had driven thanks to this stupid job, and thus when his car really should have broken down. And how much more money he would have had at that point, having worked a much better paying job the entire time. As it was, he would likely have to dip into his savings to pay for repairs.

When Nate leaned back to stretch, he realized that one of the mechanics working on his car was staring at him. It was an older man, in his 60s. Nate returned the eye contact, and watched as he spoke to one of his younger co-workers before leaving the shop floor to approach him. As they stared at each other, Nate couldn’t help but clench his keys in his jean pocket.

“Excuse me,” the mechanic said, bluntly, “are you related to someone named Ralph Guy? You look a lot like him.”

Emergency Response and Alarm Monitoring Security Services Explained

In today’s fast-paced world, workplace safety and security are more important than ever. From businesses to residential properties, the threat of theft, fire, medical emergencies, and other crises looms large. Thankfully, many security companies now offer services like emergency response and alarm monitoring to provide swift, efficient, and reliable solutions in case of emergencies. These services not only enhance the physical security of a property but also give property owners and managers peace of mind knowing that any potential crisis will be handled professionally. In this article, we will explore the essentials of emergency response and alarm monitoring services, their importance, and how they contribute to better safety and security.

Understanding Alarm Monitoring Services

Alarm monitoring is a key component of modern security services explained, especially for businesses and residential properties. It involves a system where alarms (such as burglar, fire, or carbon monoxide alarms) are connected to a central monitoring station that operates 24/7. When an alarm is triggered, it sends a signal to the monitoring center, alerting security personnel of a potential threat.

The monitoring team immediately assesses the situation by reviewing the type of alarm that was triggered. Based on the situation, they take the appropriate action, which may include notifying the property owner, contacting local law enforcement or emergency responders, or dispatching security personnel to the scene. The presence of a professional monitoring service ensures that there is always someone ready to respond, even if the property owner or manager is not on-site or unavailable.

In addition to intrusion detection, alarm systems can monitor a variety of conditions including:

Fire alarms: Detecting smoke or heat and alerting the monitoring center.

Carbon monoxide detectors: Alerting in case dangerous levels of CO are present.

Environmental sensors: Monitoring for conditions such as flooding, extreme temperature changes, or gas leaks.

By keeping properties connected to a 24/7 monitoring system, alarm monitoring services help prevent damage, loss, and injury by providing timely responses to emergencies.

The Role of Emergency Response Services

Emergency response services are the immediate actions taken to mitigate damage or harm during an emergency. When an alarm triggers, the monitoring center doesn’t just sit back and wait for further updates—they take swift action to provide a response to the event in real-time. Emergency response services may include dispatching security guards to the location, alerting the appropriate authorities (police, fire department, medical team), or providing direct intervention if needed.

In many cases, security guards may already be stationed on the property and can respond instantly to an emergency. In high-risk environments, such as warehouses, factories, or retail locations, having on-site security personnel who are trained to handle emergencies is invaluable. For example, in the case of a fire alarm being triggered, trained security staff can begin evacuating employees or visitors while simultaneously notifying emergency services and coordinating the response.

Emergency response services also extend beyond reacting to alarms. They can include routine safety checks, staff training, and the creation of detailed emergency protocols tailored to specific risks faced by the property. When all these elements are in place, emergency response services ensure that a property is equipped to handle various crises swiftly and effectively.

How Alarm Monitoring and Emergency Response Work Together

Alarm monitoring and emergency response services work in tandem to create a robust safety system. When an alarm is triggered, monitoring teams assess the situation and immediately notify the appropriate emergency responders. Meanwhile, security guards on-site can begin their own emergency procedures.

For example:

In the event of a burglary alarm, the monitoring team will notify law enforcement. Security personnel can provide a physical presence to deter the suspect or assist police when they arrive.

For a fire alarm, the monitoring center alerts the fire department, and security guards can help with evacuations, guide emergency personnel, and ensure that no one is left behind.

In case of a medical emergency, the monitoring team will call emergency medical services (EMS), while on-site guards or staff can administer first aid or assist until paramedics arrive.

This seamless coordination between the alarm monitoring system and emergency response teams ensures a fast, efficient, and organized response to any type of emergency.

The Importance of Fast Response Times

One of the greatest advantages of alarm monitoring and emergency response services is the speed with which they operate. The faster the response to a security breach, fire, or medical crisis, the less damage or injury is likely to occur. For instance, if a break-in occurs during non-business hours, the longer it takes to notice and respond, the more likely the thief is to take valuable assets. In situations such as fires or carbon monoxide leaks, the speed of response can be a matter of life and death. According to the National Fire Protection Association (NFPA), the faster emergency responders arrive, the more lives can be saved and the less damage to property occurs. Therefore, quick notification and response are critical for ensuring the safety of those involved.

A good alarm monitoring system ensures that alarms are triggered immediately upon sensing danger, which reduces the potential for false alarms or delays in response time. Security guards are also trained to make quick decisions under pressure, which is essential when lives or property are at risk.

Benefits of Professional Monitoring and Response Services

Peace of Mind

Knowing that your property is constantly monitored by professionals provides significant peace of mind. Whether you’re at home, at work, or traveling, you can rest easy knowing that your security system is active and that emergency responders will be on the case at the moment an alarm is triggered.

Reduced Response Time

The central monitoring stations operate 24/7, ensuring that alarms are always handled promptly. This leads to a faster response to emergencies, which is crucial in minimizing damage and preventing injury or loss of life.

Deterrent to Crime

The presence of alarm monitoring systems serves as a strong deterrent to potential criminals. They know that any break-in or act of vandalism will immediately trigger an alarm that alerts both the property owner and law enforcement. This reduces the likelihood of criminal activity occurring at the location.

Compliance with Regulations

Many industries are required to have certain safety measures in place to comply with local laws and regulations. Having a professionally monitored alarm system and emergency response services in place helps businesses stay compliant with safety standards, potentially avoiding penalties or insurance issues.

Customized Alerts and Responses

Professional services allow for customized solutions, so businesses and property owners can choose which types of alerts and responses they want. Whether it’s a notification for a fire alarm or a medical emergency, these services can be tailored to meet specific needs, improving the effectiveness of the system.

The Integration of Technology with Emergency Services

The advancement of technology has greatly enhanced the effectiveness of alarm monitoring and emergency response services. Modern systems can integrate features like video surveillance, real-time alerts via mobile apps, and even smart sensors that communicate directly with monitoring centers.

Smart Monitoring: Many alarm systems now come with smart features, allowing property owners to control security functions remotely. For instance, through a mobile app, users can monitor live video feeds, activate/deactivate alarms, and even unlock doors for authorized individuals.

Real-Time Communication: Some alarm systems are equipped with two-way communication, allowing the monitoring center to speak directly with the property owner or employees. This can be especially useful in emergencies when an immediate decision or action is required.

Advanced Sensors: New sensors are capable of detecting a variety of hazards, such as gas leaks, smoke, and even motion in restricted areas. These advanced tools provide more granular data, enabling quicker identification of the exact nature of the threat, allowing emergency responders to act appropriately.

Choosing the Right Alarm Monitoring and Emergency Response Provider

When selecting an alarm monitoring and emergency response provider, it’s essential to choose a company that offers reliable, 24/7 service with proven expertise. Look for a company that has a solid track record, positive reviews, and comprehensive coverage for both emergency response and monitoring services.

Factors to Consider:

Reputation and Reliability: Choose a provider with a strong reputation for reliability and prompt response times.

Customization: Ensure the provider offers customizable solutions to meet your unique security needs.

Training: Make sure that security personnel are well-trained in emergency response and emergency procedures.

Technology: Consider providers who use the latest technology for monitoring and emergency communication.

Conclusion

Alarm monitoring and emergency response services are invaluable tools for ensuring the safety and security of businesses and residential properties. With swift responses to emergencies, 24/7 monitoring, and the integration of advanced technology, these services provide peace of mind, prevent damage, and protect lives. Whether it’s preventing theft, minimizing fire damage, or responding to medical crises, these services are an essential part of any comprehensive security plan. By choosing a reputable provider, you can ensure that your property is always protected and that emergencies will be handled promptly and effectively.

For the “send me a sentence” ask game: “The cigar was perched on the side of the ashtray, a thin wisp of smoke rising, rising, rising, until it twirled into invisibility.”

“Explain.” Steward said, pointing at the offending item on the mess table.

“Cleansing the dining area of Bolian mites?” Enoch said, arranging his features into something approaching nonchalance. “The smoke kills them off.”

Steward was already halfway through pulling up a ship-wide bio scan before Enoch could finish.

“Are you accusing me of allowing an infestation? And in a recreational area of the ship, at that?”

Enoch rotated the cigar so that it smouldered evenly in the ashtray. He sighed.

“Y’know you could at least pretend to believe me.”

Steward bristled.

“Not at the expense of my hospitality protocols! An infestation! Just the thought of it!” He shuddered theatrically.

Enoch folded his arms on the table and rested his chin on them, watching the smoke coil almost imperceptibly in the still air.

“I miss how the ship used to smell.”

“You can’t smell,” Steward closed his folio.

“Fine. I miss how the ships internal atmospheric sensor data used to intermittently spike with nitrogen, carbon monoxide, and benzene.”

“You miss the benzene?”

“I miss him.”

Steward reached out, paused a second to overthink, and then patted Enoch on the back. Twice. The ‘there there’ was implied in the tempo.

“Well, we’re still working on it, aren’t we?” The hospitality hologram tried to sound hopeful. “Come on, Emil’s in the holosuite, he thinks he might have made a breakthrough…”

Measuring moon dust to fight air pollution

Moon dust, or regolith, isn't like the particles on Earth that collect on bookshelves or tabletops—it's abrasive and it clings to everything. Throughout NASA's Apollo missions to the moon, regolith posed a challenge to astronauts and valuable space hardware.

During the Apollo 17 mission, astronaut Harrison Schmitt described his reaction to breathing in the dust as "lunar hay fever," experiencing sneezing, watery eyes, and a sore throat. The symptoms went away, but concern for human health is a driving force behind NASA's extensive research into all forms of lunar soil.

The need to manage the dust to protect astronaut health and critical technology is already beneficial on Earth in the fight against air pollution.

Working as a contributor on a habitat for NASA's Next Space Technologies for Exploration Partnerships (NextSTEP) program, Lunar Outpost Inc. developed an air-quality sensor system to detect and measure the amount of lunar soil in the air that also detects pollutants on Earth.

Originally based in Denver, the Golden, Colorado-based company developed an air-quality sensor called the Space Canary and offered the sensor to Lockheed Martin Space for its NextSTEP lunar orbit habitat prototype. After the device was integrated into the habitat's environmental control system, it provided distinct advantages over traditional equipment.

Rebranded as Canary-S (Solar), the sensor is now meeting a need for low-cost, wireless air-quality and meteorological monitoring on Earth. The self-contained unit, powered by solar energy and a battery, transmits data using cellular technology.

It can measure a variety of pollutants, including particulate matter, carbon monoxide, methane, sulfur dioxide, and volatile organic compounds, among others. The device sends a message up to a secure cloud every minute, where it's routed to either Lunar Outpost's web-based dashboard or a customer's database for viewing and analysis.

The oil and gas industry uses the Canary-S sensors to provide continuous, real-time monitoring of fugitive gas emissions, and the U.S. Forest Service uses them to monitor forest-fire emissions.

"Firefighters have been exhibiting symptoms of carbon monoxide poisoning for decades. They thought it was just part of the job," explained Julian Cyrus, chief operating officer of Lunar Outpost. "But the sensors revealed where and when carbon monoxide levels were sky high, making it possible to issue warnings for firefighters to take precautions."

The Canary-S sensors exemplify the life-saving technologies that can come from the collaboration of NASA and industry innovations.

Internet of forest things

(...)

Wallrabe and her fellow researchers are working on a range of devices that will be deployed from the ground to the treetops, transmitting data from Germany’s Black Forest to their labs at the University of Freiburg. At the same time, scientists and engineers at other companies are also focused on making their devices unobtrusive and, ultimately, self-sustaining.

Silvanet Wildfire Sensor

Time is of the essence when fighting forest fires. Sensors attached to trunks “smell” tell-tale gases like hydrogen and carbon monoxide, and alert firefighters within the first hour—before satellites or cameras can spot open flames. German startup Dryad Networks has built AI into its solar-powered sensors to ensure that they can distinguish between real fires and, say, passing diesel trucks.

Treevia

Digital dendrometers relieve foresters of tedious work. As trees grow, the elastic band wrapped around their trunk stretches and transmits data directly to a computer. The lightweight device from Brazilian startup Treevia can even be attached to saplings. It also contains a humidity and heat sensor, providing insights into climatic impacts on reforested areas.

The Guardian

What does it take to catch illegal loggers or poachers? A smartphone is a good start. Rainforest Connection’s recycled, solar-powered smartphone listens for the sound of chain saws or gunshots within a 1-mile radius. The recordings are transmitted to the cloud for analysis and alert local authorities in near real time. This device also provides insights into the distribution and calling behavior of animals.

BiodivX Drone

As animals move through trees, they shed DNA through feces, skin, and hair. This innovative drone collects what is known as environmental DNA (eDNA) from leaves and branches—with particles sticking to its adhesive strips. Scientists from Switzerland programmed the drone so it can navigate autonomously through dense forests and hover steadily around branches to take samples.

Leaf Sensor

Wallrabe and her team at the University of Freiburg have developed a glass capsule that measures gas exchange between a leaf and its surroundings. It can detect specific chemicals that trees emit under stress, for example, in the event of a drought, infestation, or disease. The capsule is transparent so that sunlight can reach the leaf without impairing its function.

Plant-e

When sunlight is limited, most devices are powered by batteries. Plant-e, a Dutch company spun out of Wageningen University, makes use of a natural process: Plants produce organic material through photosynthesis; some they use for growth, the rest ends up into the soil. Bacteria break down this material and release electrons that Plant-e uses to power its sensors....

The most ridiculous thing happened to me last night. I was sitting watching a passable Christmas romcom when suddenly the fire alarms started going off. I live in a town house, and I have two that are linked and they talk, because they also do carbon monoxide detection.

So it started saying “FIRE FEU” [bilingual due to being Canadian] while the alarm was going off. So my mom and I jump up and run around to see where the fire is and we can’t find anything, we also can’t smell anything, and it eventually stopped. But then it goes off again and we wonder if the backup batteries are dying and that is why it’s going off. So I frantically change the batteries while my eardrums are being tortured with shrieking and “FIRE FEU”. And they stop going off and I think that it solved the problem. But then the alarm upstairs starts saying “BATTERY BATTERY BATTERY” and I have put that one in backwards. So I fix it.

Then it dawns on me that if it was the battery issue it would have been yelling “BATTERY BATTERY BATTERY” at me. And it starts going off again, this time I try just pressing the test button and the only difference is that it starts screaming “CARBON MONOXIDE CARBON MONOXIDE” and then I’m again freaking out because you can’t smell carbon monoxide. So we open some doors.

Then I decide to try looking outside to see if my neighbours have a fire and somehow our alarm is noticing it before we are, and there is nothing but the alarm has also stopped.

So I look up “fire alarm going off for no reason” and I find out that they can get dusty so I decide to vacuum them, while still attached to the ceiling, and every time I try something new I have to lug the ladder up and down the stairs, just to paint an accurate picture.

The alarm seems to have stopped and it is quiet for about twenty minutes, and I have been lulled into a false sense of security. It goes off again and I am just about at the end of my rope, and I find an article suggesting using canned air, like the kind you use to clean a keyboard. And thankfully we do have some.

So I get back on the damn ladder and spray the shit out both alarms and I notice that one has a solid green light but one has an intermittently blinking green light. More internet searching tells me that means that is the alarm that is detecting the mystery smoke. And I need to reset it, which sets the alarm off again to do the test. My eardrums are crying, I am pissed, but I think I solved the problem.

I go back downstairs, have another twenty minutes of peace and then “FIRE FEU FIRE FEU” and I am furiously swearing at the smoke detector, I drag the ladder back upstairs, I remove it from the ceiling and unplug the main power line. I am going to get the dust out of the smoke detector or I am going to burn the house down, if it wants smoke, it will get smoke.

I take the can of air, my mom is standing in solidarity with me and the can, and I spray it from every angle possible. And then. With the last puff, out pops a very small white spider, we all gasp (probably including the spider, who’s reign of terror is as about to end) and he falls on the floor, and is immediately crushed by a Birkenstock sandal.

And the ordeal is not over because getting that fucking alarm back on the ceiling took me seventeen tries, but no more “FIRE” no more “FEU”, no more “CARBON MONOXIDE” and no more fire alarm.

So if your fire alarm even goes off for seemingly no reason, it could be that the spirit of Puck has possessed a small spider and he is trying to build a web right in front of the smoke sensor.

A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets. The cameras use sensitive, high-resolution strained-layer superlattice sensors, initially developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, using IRAD, Internal Research and Development funding. Their compact construction, low mass, and adaptability enable engineers like Tilak Hewagama to adapt them to the needs of a variety of sciences. Goddard engineer Murzy Jhabvala holds the heart of his Compact Thermal Imager camera technology – a high-resolution, high-spectral range infrared sensor suitable for small satellites and missions to other solar-system objects. “Attaching filters directly to the detector eliminates the substantial mass of traditional lens and filter systems,” Hewagama said. “This allows a low-mass instrument with a compact focal plane which can now be chilled for infrared detection using smaller, more efficient coolers. Smaller satellites and missions can benefit from their resolution and accuracy.” Engineer Murzy Jhabvala led the initial sensor development at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as well as leading today’s filter integration efforts. Jhabvala also led the Compact Thermal Imager experiment on the International Space Station that demonstrated how the new sensor technology could survive in space while proving a major success for Earth science. More than 15 million images captured in two infrared bands earned inventors, Jhabvala, and NASA Goddard colleagues Don Jennings and Compton Tucker an agency Invention of the Year award for 2021. The Compact Thermal Imager captured unusually severe fires in Australia from its perch on the International Space Station in 2019 and 2020. With its high resolution, detected the shape and location of fire fronts and how far they were from settled areas — information critically important to first responders. Credit: NASA Data from the test provided detailed information about wildfires, better understanding of the vertical structure of Earth’s clouds and atmosphere, and captured an updraft caused by wind lifting off Earth’s land features called a gravity wave. The groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher resolution: 260 feet (80 meters) per pixel from orbit compared to 1,000 to 3,000 feet (375 to 1,000 meters) possible with current thermal cameras. The success of these heat-measuring cameras has drawn investments from NASA’s Earth Science Technology Office (ESTO), Small Business Innovation and Research, and other programs to further customize their reach and applications. Jhabvala and NASA’s Advanced Land Imaging Thermal IR Sensor (ALTIRS) team are developing a six-band version for this year’s LiDAR, Hyperspectral, & Thermal Imager (G-LiHT) airborne project. This first-of-its-kind camera will measure surface heat and enable pollution monitoring and fire observations at high frame rates, he said. NASA Goddard Earth scientist Doug Morton leads an ESTO project developing a Compact Fire Imager for wildfire detection and prediction. “We’re not going to see fewer fires, so we’re trying to understand how fires release energy over their life cycle,” Morton said. “This will help us better understand the new nature of fires in an increasingly flammable world.” CFI will monitor both the hottest fires which release more greenhouse gases and cooler, smoldering coals and ashes which produce more carbon monoxide and airborne particles like smoke and ash. “Those are key ingredients when it comes to safety and understanding the greenhouse gases released by burning,” Morton said. After they test the fire imager on airborne campaigns, Morton’s team envisions outfitting a fleet of 10 small satellites to provide global information about fires with more images per day. Combined with next generation computer models, he said, “this information can help the forest service and other firefighting agencies prevent fires, improve safety for firefighters on the front lines, and protect the life and property of those living in the path of fires.” Probing Clouds on Earth and Beyond Outfitted with polarization filters, the sensor could measure how ice particles in Earth’s upper atmosphere clouds scatter and polarize light, NASA Goddard Earth scientist Dong Wu said. This applications would complement NASA’s PACE — Plankton, Aerosol, Cloud, ocean Ecosystem — mission, Wu said, which revealed its first light images earlier this month. Both measure the polarization of light wave’s orientation in relation to the direction of travel from different parts of the infrared spectrum. “The PACE polarimeters monitor visible and shortwave-infrared light,” he explained. “The mission will focus on aerosol and ocean color sciences from daytime observations. At mid- and long-infrared wavelengths, the new Infrared polarimeter would capture cloud and surface properties from both day and night observations.” In another effort, Hewagama is working Jhabvala and Jennings to incorporate linear variable filters which provide even greater detail within the infrared spectrum. The filters reveal atmospheric molecules’ rotation and vibration as well as Earth’s surface composition. That technology could also benefit missions to rocky planets, comets, and asteroids, planetary scientist Carrie Anderson said. She said they could identify ice and volatile compounds emitted in enormous plumes from Saturn’s moon Enceladus. “They are essentially geysers of ice,” she said, “which of course are cold, but emit light within the new infrared sensor’s detection limits. Looking at the plumes against the backdrop of the Sun would allow us to identify their composition and vertical distribution very clearly.” By Karl B.

Everyone wants a robotgirl until your carbon monoxide sensors keep going off

Yay Betty the 1954 Stove had been fixed!

Part of the problem is that the oven temperature gages you can buy for home use are apparently garbage and mine was off by 30 degrees. So the actual oven thermometer was only off by 20 degrees.

Ol' Darryll has been in the business just long enough to know that back in the day there used to be adjusters for the thermostats so you could retune them as they aged instead of just replacing them.

Here's mine under the oven knob.

ID: A white porcelain stove edge with a chrome circular dial holder. In the center are three small flathead screws the center one has a thin metal triangular hand pointed up. End ID.

So what you do is loosen the two outer screws (do not remove) and that lets you adjust the center one colder or hotter.

Now this era of mechanical temperature sensors have an accuracy range of about 10 degrees up or down and are really sensitive. So he got it about 12 degrees under the dial temp and said if he adjusted it more it would probably end up too hot. So just nudge the dial a little over the line and it'll be fine. She'll never be as accurate as a modern digital thermometer but I'm also not a baker so it's fine for me. Mostly she's on tater tot duty.

This is such good news because a new temperature sensor is likely to be a hard to find antique part and this stove is before his time so he's not super familiar. Also the model and serial number have worn off for an extra part identifying challenge. (The temperature gauge itself might have a model number on it.)

Anyway, she's back plodding away after 69 years of continuous use. Not gonna get that kind of longevity out of a modern stove. (Just keep three carbon monoxide sensor in operation close by in case something goes wrong so she doesn't kill us all. She's also not as efficient as a modern stove (pilot lights and the oven takes a while to heat up). But she represents where we were as a society before corporate capitalism's enshitification of everything took hold. There's no reason we can't build appliances today that last at least 30 years, let alone 70.

I love her.

ID: Betty, a white and chrome 1952-1954 O'Keefe and Merritt range with 4 burners, a griddle, three crumb catcher trays, a regular oven with a window, a broiler oven with a solid door, a pan drawer, and a service door. She has a tall back with a cover that can be folded up like a half shelf or folded out to cover the burners. The top has a (broken) timer, a baking temperature guide, salt and pepper shakers, a long narrow light, an electrical plug and a sculptural top design. On top of it is a pie bird, a fancy salt shaker, and an herb jar. Over it is a huge white and chrome hood that has a red mechanical timer and magnetic red spice jars stuck to it. There are white subway tiles behind it. With a black accent line. The surrounding cabinets are mint green with butcher block tops. A microwave, antique toaster, copper kettle, cooking utensils jar, and various other useful things are in the counter or in shelves. End ID.

The MQ9 Gas Sensor is a member of the MQ Gas Sensors family. It operates as a Metal Oxide Semiconductor (MOS) gas sensor primarily designed to identify Carbon Monoxide, Methane, and Propane. It is capable of detecting concentrations of LPG, Propane, Hydrogen, Carbon Monoxide, and Methane gases. The sensor contains a sensitive element, primarily composed of aluminum-oxide-based ceramic coated with Tin dioxide (SnO2), enclosed within a stainless-steel mesh. When gases come into contact with this element, it causes a change in its electrical resistance. This alteration is then measured to determine the concentration of the gases. The sensor features a small heating element that preheats the sensor to bring it into the operational range.

It is widely used in applications involving the detection of gas leaks in pipelines and alarms for home safety.

Have you checked your carbon monoxide sensor lately

😭

[noegrets]

First, a little background history. Canaries were used in mines from the late 1800s to detect gases, such as carbon monoxide. The gas is deadly to humans and canaries alike in large quantities, but canaries are much more sensitive to small amounts of the gas, and so will react more quickly than humans. This was discovered by John Haldane, who was asked to help determine the cause of an explosion at Tylorstown Colliery in 1896. He concluded the explosion was caused by a build-up of carbon monoxide and set out to find a way of detecting the odourless gas before it could harm humans. The result was this cage and its captive canary. [...] Firstly, while I don’t advocate the use of animals in testing dangerous conditions, I am pleased that Haldane spared a thought for the canaries themselves and worked to make their job as non-lethal as possible. My impression from hearing about canaries in coal mines was that they were expected to die to warn people, so when I came across this object it was a huge relief (though my research on the topic has found less thoughtful cages). I’ve even read that many miners cared deeply for their canary companions, and some disliked the advent of electronic sensors in the mid-1980s because it meant they would lose this companionship. Personally, I’m pleased that this practice has come to an end. Another reason this is my favourite object is because it isn’t pristine. It’s scuffed and has clear signs of wear from use. This may sound strange, but when it comes to museum objects we often prefer the ones that are a little beaten up. They add more context and show how the object may have been used. We are able to research and understand much more from a used example than a pristine one. [...] Our museum aims to tell the history of innovation relating to science and industrialisation, and we often show that this history isn’t a clean one. We have objects that are dirty or damaged, or perhaps represent difficult topics, and I personally wouldn’t have it any other way. If we were to scrub away the dirt, or hide the dark spots, then the histories we tell wouldn’t be true. So, my favourite object is a mucky and damaged box, in which a canary would have been caged, and used as an indicator of dangerous conditions. It’s not pretty, and it’s cruel to the animal, but it is representative of an innovation in mining practices, and our understanding of gases and bird physiology. It lets us tell interesting histories, and it’s a great example of how scientific understanding leads to changes in industrial practices, which is one of our major themes at this museum.

You know how canaries were historically brought into coal mines, because if the mine was full of carbon monoxide the canary would die first and the miners would be able to escape before they died too?

I just found the greatest thing.

This is a canary resuscitator.

When the miners notice the canary getting sick with carbon monoxide poisoning, they can close that circular hatch so no more gas gets into the canary cage, and open the valve on that oxygen tank to keep the canary breathing. In other words, they made a spacesuit for birds.

By immediately giving the canary access to clean air, the miners can save it from the poison. The bird lives. To be clear, this is not for economic purposes, this was specifically created because the miners felt bad and wanted to save the bird.

Isn’t that just the perfect demonstration of what humans are like? We started sacrificing small creatures to save ourselves, and then felt bad and spent our valuable resources on saving the critters too. Because yeah the canary was the only way to test for CO, but it’s a living creature too, dammit!
