The Amazing World of Sensor Detectors are devices that detect and respond

What are Detectors? Detectors are devices that detect and respond to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any other physical phenomenon that can be measured. By converting the input to an electronic signal, detectors enable monitoring and automating real-world processes.

Types of Common Detectors There are many different types of detectors based on the specific input they are designed to detect. Here are some of the most common detectors used today:

Light Detectors Light detectors detect illumination levels and are used commonly in automatic lighting controls, camera auto-focus systems, and digital clocks that glow in the dark. Common light detectors include photo resistors, photo diodes, and photo transistors that change their electrical properties depending on the amount of light striking their active surface.

Temperature Sensor Temperature detectors measure ambient or surface temperature and often output an analog voltage that varies with temperature. Sensor Thermistors and thermocouples are widely used temperature detectors. Thermocouples generate a small voltage proportional to the temperature difference between two junctions of dissimilar metals. Thermistors change their electrical resistance with temperature in a known manner. Temperature detectors find applications in thermostats, medical equipment, heating/cooling systems and more.

Motion Detectors Motion detectors detect movement of objects and people. Passive infrared (PIR) motion detectors are commonly seen in outdoor lighting and security systems. Ultrasonic motion detectors detect motion by sensing changes in ultrasonic patterns. Optical mouse detectors also fall into this category as they sense motion and movement. Industrial robots often use motion detectors to detect position and speed.

Pressure Detectors Pressure detectors measure the force per unit area applied on their surface. Strain gauge pressure detectors change their electrical resistance with the amount of applied pressure. They are used to measure everything from tire pressure to blood pressure. Capacitive pressure detectors use capacitance changes to sense pressure. Piezoresistive pressure detectors alter their electrical resistance when strained under pressure.

Proximity Detectors Proximity detectors indicate if an object is near or within a given distance range without physically touching it. Common proximity detector technologies include ultrasonic, infrared, inductive loops, and laser optical. They find widespread use in industrial machine automation, assembly lines, and object detection applications.

Advancing Micro-Detector Technology As microchip fabrication technology advances, detectors are becoming smaller, cheaper, and more powerful. Microelectromechanical systems (MEMS) allow detector features to be integrated directly onto silicon chips alongside digital circuits. This opens up many new possibilities for pervasive sensing across diverse industries.

Tiny environmental detectors based on MEMS accelerometers and gyroscopes enable motion-activated user interfaces and electronic stability control in vehicles. MEMS pressure detectors monitor engine performance and structural stress. MEMS microphone arrays support speech-enabled user interfaces and noise cancellation. Miniature biodetectors based on chemical detectors, bio-implants, and DNA/RNA identification promise to revolutionize personal healthcare.

The Internet of Things (IoT) is accelerating detector innovations further by connecting everyday objects and environments to the internet. Embedded with detectors, things like home appliances, industrial equipment, vehicles, medical devices, infrastructure, and consumer goods continuously monitor their own status and environmental conditions. Wireless MEMS pressure and temperature loggers track shipments. Smart lighting uses embedded motion and light detectors for enhanced efficiency and user experiences. Detectors will further shrink and proliferate in the coming years towards realizing a fully sensed world.

Future Directions in Sensor Technologay By combining multiple detector capabilities on single chips, we can sense increasingly complex phenomena. Multidetectory systems merge data from MEMS accelerometers, magnetometers, gyroscopes, and microphones to accurately track motion, orientation, and location in three-dimensional spaces. Advanced data processing allows taking inputs from diverse detector arrays to identify odors, flavors, textures, and properties beyond the scope of individual detectors.

Biodetectors and chemical detectors hold much promise in areas like biomedical testing, environmental monitoring, and healthcare. Rapid DNA sequencing using nanodetectors may enable non-invasive, real-time medical diagnostic tests. Taste detectors that mimic human physiology could revolutionize food quality assessment. Small, low power gas detectors networked throughout smart buildings may help detect hazardous leaks instantly. Continued research is sure to yield new types of detectors we have not even imagined yet.

Sensor play a huge role in our world by enabling the interaction between electronics and the real world. Constant advancements in microfabrication and computing power are expanding sensing capabilities to unprecedented levels with each new generation of technology. In the future, sensing will become even more pervasive, intelligent and seamlessly integrated into our daily lives for enhanced convenience, safety, sustainability and scientific discovery.

Concept: the Staff of Forbidden Spinjitzu doesn't whisper to Zane. Instead, its "whispers" take the form of popups along his HUD disguised as alerts or warnings. Things like "If you put me down now, your friends will never find you. [OK]” or “Killing these prisoners villagers will increase Vex’s approval and reinforce your reign. Proceed? [Y/N]”

(I like this particular flavor because it really leans into Zane's robotic nature: he can ignore whispers by turning off his auditory sensors or filtering noise, but he can't ignore system alerts.)

Also, the following scene has lived rent-free in my brain ever since I came up with the concept. (Italics are Zane's default OS. Everything else is the Staff.)

>IF YOU ARE GOING TO DESTROY ME, "ZANE" -Move File:"NeverrealmMemories" to Core Memory Functions-WARNING: Attempting to delete, move, or suppress File"NeverrealmMemories" after moving will cause total system failure. Proceed with move anyway? >[YES] -File transferred. -Permanently remove fatal combat safeguards? >[YES] -Safeguards removed. >THEN I WILL MAKE SURE YOU CAN NEVER FORGET WHAT YOU DID, SYSID:ICEEMPEROR

-Connection Terminated.

(I have a few more Ideas for the "Scroll Corruption looks like Computer Alert messages to Zane" idea-ones that really lean into Zanes Nindroid nature, as well as the tech-y appearance of the Dark Ice.) -The Staff did a lot more than just send alert messages: it slowly wormed its way into Zane's code like a computer virus, tweaking a few things. It took great care to remove Zane's combat safeguards, eventually deleting them entirely and ensuing he defaulted to lethal force. It never removed his core directive of "Protecting those who cannot protect themselves" since that was vital to his systems running, but it did reinterpret said directive as "Protect Dark Ice Network and everything connected to it, for it is fragile and cannot protect itself from outsiders". (It also couldn't delete his morality subroutines without causing a crash, so it instead made them a much lower priority and shoved them to the back of his digital mind.) -After 60+ years of being in the grasp of a mechanical being, the Staff now exclusively speaks in the manner of a computer, and cannot adapt to organic minds the way it used to. (The other Staff is not like this, as it's still attuned to organic brains.) -You know those Sci-Fi stories where people are plugged into computers and know every part of the ship/city simultaneously, and can send most of their awareness into certain parts of the network while still being aware of other locations? That's what's going on with the Never Realm during the Ice Emperor's Reign, with the Ice Emperor as the central guiding consciousness/core CPU of the Dark Ice Network. As such, he's not actually sleeping-rather, the Ice Emperor is always monitoring his domain through his Ice and leaving just enough of his consciousness in his body to be able to call the rest of himself back in case he's threatened. (The Staff is a combination of a computer virus and a wireless modem: it is corrupting, but it's also the main point of connection for the Dark Ice Network.) -Since the Ice Emperor can't recharge his power on his own in his current state, the Staff had to step in, tweaking the Dark Ice to drain the vitality of those imprisoned within. (You know wireless phone chargers, or Nikolai Tesla's idea to get electric power from the atmosphere? Similar concept, except with the power source being frozen people and the transmitter being Evil Magic Ice.) -Boreal is the Titanium Dragon, corrupted by the Staff's presence. It too is part of the Dark Ice Network, and serves as Ice Emperor's eyes and ears whenever the Dark Ice can't reach. (If the Ice network used computer program language, Boreal would be known as "Obj_DarkIceTitaniumDrake".) Killing Boreal caused a massive jolt to the Dark Ice Network that destabilized the Scroll's influence, and allowed an opening for Zane's Memory Defragmentation program to kick in. (It had started when Lloyd arrived in the throne room, but the Scroll had diverted that to a minor priority and was actively hiding that set of files until the word "Protect" slipped through, forcing Zane's systems to call up what had been defragmented.) -As a final act of spite for being broken, the Staff encoded Zane's memories of the Never realm to his Core Processing systems, meaning he cannot forget the Never Realm without completely frying his systems and rendering him a lifeless shell. (It might've also made a backup of itself amidst his various repressed memory files, but he doesn't need to know that. It's just sitting there, disguised as a normal .zip file, biding its time.) (I really like genre-blending Sci-Fi and Fantasy, and I thought the idea of "Magic Ice Computer Network" is rad as hell.)

(This song is a big part the inspiration for part of the "Dark Ice Network" idea, by the way. Granted, the Staff of Forbidden Spinjitzu doesn't assimilate Zane's psyche like Star Dream assimilates Haltmann's, but a lot of the ideas are still there-and the Staff does still integrate itself pretty deeply into the Nindroid's code as it slowly actualizes.)

I have no words for how absolutely awesome this is in every way. i just keep rereading this and being amazed. the "Dark Ice Network" idea is literally so cool, I particularly love the Ice Emperor being able to monitor the entire land while his body/the staff is the main 'hub' he has to protect. this is aweosme.

everyone look now please

There’s a thought stirring in Bridge’s mind. An idea rolling about and nudging against the capacitors in her head, poking and prodding incessantly to get her attention, “Hey, hey, you know you want to ask her. Don’t you? Don’t lie to yourself, now. You should just do it. Hey! Are you listening to me? Hello-o…?”

Yes. Yes, she knows, she is aware of her burning curiosity. And it’s hard to deny that even though it doesn’t involve her, she is unusually intrigued by the concept. She overheard them in his office, Miguel and LYLA–his A.I. assistant–discussing a plan.  A plan to create a physical form for LYLA to enhance her abilities as his assistant and grant her further autonomy beyond her access to the security network and other adjacent systems alongside her recent emergence into emotional intelligence. It was all so fascinating. The steps Bridge had taken herself in her development in the span of weeks, she was watching unfold in another intelligence in real-time.

There it was again. That sense of solidarity in knowing she wasn’t completely alone in her existence as an artificial being, made of code and metal. It was like a magnetic pull that made that little voice in her head that encouraged her to act on her wants all the more present in her mind. She wanted to be a part of that process that she’d been through so long ago yet was still so familiar with like it happened yesterday. She wanted to guide her in that process and grant her her own knowledge. What’s the worst that can happen if she pilots your hardware for a while? You’re prepared for this. You can handle this. You can trust her, and she will be entirely safe in your care for that short time. And think about how much she would benefit from the experience, how much more streamlined that eventual transition from intangible to tangible will be once her own body was complete. It will make all the difference–and maybe reduce the headaches for everyone all-around, mostly Miguel as he acclimates to the change himself. Just… Try it. You can’t account for every single last risk factor, can you? No. So just do it and take it as it comes.

She stood in the middle of her dorm a moment, eyes closed as she ran a quick check of her hardware before making her final decision. RAM is in good condition. Storage is defragmented and all directories are organized. Sensors are calibrated and functional. Nanomachines are synchronized properly. Servos and joints retain a full range of motion. Coolant is at above optimal operational temperatures. Energy reserves are complete. Good. Everything’s in its right place and ready for its–potentially–temporary host. It’s time to make the call.

Her gaze trains itself on her watch, her arm rising to eye-level and the sleeve that was weighed down by the leaden metal cuff at the end sliding to her forearm to reveal device so she can start the transmission, navigating the menus on the digital interface indirectly via wireless communication–the unique way that she operated and communicated the Society’s technology.

“LYLA, may I speak to you for a moment? At your leisure, of course.”

How Do F1 Cars Work?: Braking, Cooling, Sensors

I never know how to start these posts. Let's dive in.

Braking and Cooling

Brakes are an incredibly important part of any car, but most especially in F1. With the speed and power the cars have a sensitive, sturdy, and strong braking system must exist. In the case of modern cars, F1 uses an extremely efficient and durable carbon-carbon disc brake system. This allows the car to screech to a halt in a split-second, and allows drivers to use their speedy reaction times to the best of their ability. When the driver steps on the brake pedal, it compresses two master brake cylinders, one for the front wheels and one for the rear, which generate fluid pressure.

For the front tires, the fluid pressure is delivered directly to the front brake calipers (part that houses brake pads and pistons). Inside each caliper, six pistons clamp pads against the disc and it is this friction that slows the car down. For the rear tires it is a bit different.

At the rear, the car can brake by three separate sources: friction from the brakes, resistance from the spinning engine (engine braking) and electrical braking that results from harvesting energy from the MGU-K . Although the driver can adjust each of these on his steering wheel, when he presses the brake pedal, the three systems work together via the Brake By Wire (BBW) system.

When the driver presses the pedal, the fluid pressure generated in the rear braking circuit is picked up by an electronic pressure sensor. The signal from this sensor represents the overall rear braking demand from the driver and is passed to the Electronic Control Unit (ECU) where it is turned into a series of commands to brake the rear of the car. The ECU distributes its efforts to the three systems according to the the set up of the car and this is altered by the way that the driver has adjusted the switch settings on the steering wheel. This is what teams mean when they say changing the setting on the car.

Going hand-in-hand with braking, cooling is another important part of the car, especially for brakes. Basically, there is a series of systems that cools the power unit, brakes, and electronics. If the car overheats, it can lead to damage and lack of performance. There are a few ways to cool. Radiators cool the engine and hybrid system. Intercooler cools the air that the turbocharger compresses before it enters the engine. Brake cooling ducts bring air to the brakes in order to stop them from overheating.

2. Electronics and Sensors

So i'm sure many of you have looked at the steering wheel and been baffled that this thing that looks like a Nintendo Switch steers that car. The F1 steering wheel is incredibly complex and has a variety of buttons, screens, and knobs. For example, on the steering wheel is an area for strat settings, where their plans for all eventualities are mapped out. There is also a rotary knob for MGU-K settings, where drivers can switch around when faced with possible failures. The menu allows drivers control over every setting in the car. Beyond that there is the pit lane speed button, gear change buttons, race start button, energy recovery button, and brake balance knob, among others. It really tells you how much drivers do in a race beyond racing.

Other than the steering wheel, there is also the telemetry, over 300 sensors which gathers race data and sends it back to engineers on the pit wall. This way, engineers can either remotely alter settings and strat, or advise the driver on what to do.  F1 uses a customized mesh wireless network system based on WiMax 802.16 at each racetrack. The sensors record data, which is then temporarily stored in the Electronic Control Unit (ECU), which controls functions like engine performance and power steering. That sensor data then travels wirelessly to a centralized location managed by F1. F1 then sends the data to the relevant team, of course very securely. Teams then use a system called Advanced Telemetry Linked Acquisition System (ATLAS) to view and analyze sensor data.

The final pretty important electronic devices on an F1 car is the many many cameras. The most recognizable camera is found in the "T" structure that sits atop of every F1 car. It gives viewers that top-down, forward facing view used often by broadcasters. this is also how viewers often distinguish between cars of the same team. One driver will have a yellow camera, the other has black. The two nose cameras provides a view of the front wing and low circuit. The 360 camera is on top of the chassis and provides a wide view of the race track, and everything else around the car. The driver facing camera is pointed directly at the driver and helps keep track of how they are doing, and in the event of the crash helps marshals and rescuers figure out the best way to help. The two rear cameras are settled on a rear facing structure, and allows the pit wall to see what is going on directly behind the driver and advise. Beyond these ones, drivers also have cameras inside their helmets, showing exactly what they see. Can't get away with much in an F1 car.

3. How They Work Together

So, we now know the basics of most parts of the car. But these parts all must work together before that car will go anywhere. How do they do it?

One of the more obvious relationships is between aerodynamics and power. The better the aerodynamics, the more usable the power is. They also work in tandem around different parts of the track. On corners the aerodynamics keep the car stable while the power peters off. On straights the power keeps the car boosted. Suspension and tires are also very connected. It is the suspension that keeps the tires on the ground. A good suspension will also mean that the tires are easier to manage, something any driver knows is highly important. Brakes and ERS are also connected because the brakes help recover ERS, pretty simply. Also the cooling system works with most of teh car, cooling engine, tires, and brakes. The biggest connection is probably between all the sensors on the car. They are connected to every single part, and even a small bit of damage can destroy them. The non-sensor components have to accommodate for the sensors and work perfectly with them in order for proper data to be sent back.

The ultimate goal of engineers is to create a car that works in harmony all together. The integration of the engine to the chassis is highly important. There have been cars that the parts were fantastic on their own, but the minute they were put together stopped working completely. Its why teams that produce their own engines have such a leg up over non-manufacturers. Its also why sometimes you will see a car that is running poorly until one small thing is changed, and then suddenly its brand new. Car harmony really is terribly important.

Alright, done! While I covered most of the important stuff, as always if there is any particular part of the car anyone wants me to dive deeper into, please let me know.

Cheers,

Battery-free technology can power electronic devices using ambient radiofrequency signals

Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module—developed by a team led by scientists from the National University of Singapore (NUS)—can now convert ambient or "waste" RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries. RF energy harvesting technologies, such as this, are essential as they reduce battery dependency, extend device lifetimes, minimize environmental impact, and enhance the feasibility of wireless sensor networks and IoT devices in remote areas where frequent battery replacement is impractical. However, RF energy harvesting technologies face challenges due to low ambient RF signal power (typically less than -20 dBm), where current rectifier technology either fails to operate or exhibits a low RF-to-DC conversion efficiency. While improving antenna efficiency and impedance matching can enhance performance, this also increases on-chip size, presenting obstacles to integration and miniaturization.

Robovie II (2002) by Advanced Telecommunications Research Institute International (ATR), Kyoto, Japan.

"The advanced version of the Robovie II android being developed by the Advanced Telecommunications Research Institute (ATR) has been designed with the aim of making shopping an easier and more entertaining experience for seniors. The android is part of a bigger network of sensors and wireless devices, with the customer’s experience beginning before they even enter the store. A user inputs their shopping list on a mobile device from home, telling the robot’s on-screen avatar what they require. This information is wirelessly transmitted to a waiting robot, which greets the customer by name as they enter the supermarket. The robot then proceeds to carry the user’s shopping, verbally read out the next item to be collected while also making suggestions for suitable additional items. Robovie II is currently being tested in the Apita Seikadai supermarket in Kyoto." – Robovie II - the personal robotic shopper, New Atlas
