For the Benefit of All: Assistive Tech Developed from NASA Tech

What do modern cochlear implants and robotic gloves have in common? They were derived from NASA technology. We’ve made it easier to find and use our patented inventions that could help create products that enhance life for people with disabilities.

October is National Disability Employment Awareness Month, which highlights the contributions of American workers with disabilities – many of whom use assistive technology on the job. Take a look at these assistive technologies that are NASA spinoffs.

Low-Vision Headsets

The Joint Optical Reflective Display (JORDY) device is a headset that uses NASA image processing and head-mounted display technology to enable people with low vision to read and write. JORDY enhances individuals’ remaining sight by magnifying objects up to 50 times and allowing them to change contrast, brightness, and display modes. JORDY's name was inspired by Geordi La Forge, a blind character from “Star Trek: The Next Generation” whose futuristic visor enabled him to see.

Cochlear Implants

Work that led to the modern cochlear implant was patented by a NASA engineer in the 1970s. Following three failed corrective surgeries, Adam Kissiah combined his NASA electronics know-how with research in the Kennedy Space Center technical library to build his own solution for people with severe-to-profound hearing loss who receive little or no benefit from hearing aids. Several companies now make the devices, which have been implanted in hundreds of thousands of people around the world.

Robotic Gloves

Ironhand, from Swedish company Bioservo Technologies, is the world’s first industrial-strength robotic glove for factory workers and others who perform repetitive manual tasks. It helps prevent stress injuries but has been especially warmly received by workers with preexisting hand injuries and conditions. The glove is based on a suite of patents for the technology developed by NASA and General Motors to build the hands of the Robonaut 2 humanoid robotic astronaut.

Smart Glasses

Neurofeedback technology NASA originally developed to improve pilots’ attention has been the basis for products aimed at helping people manage attention disorders without medication. The devices measure brainwave output to gauge attention levels according to the “engagement index” a NASA engineer created. Then, they show the results to users, helping them learn to voluntarily control their degree of concentration. One such device is a pair of smart glasses from Narbis, whose lenses darken as attention wanes.

Anti-Gravity Treadmills

A NASA scientist who developed ways to use air pressure to simulate gravity for astronauts exercising in space had the idea to apply the concept for the opposite effect on Earth. After licensing his technology, Alter-G Inc. developed its anti-gravity G-Trainer treadmill, which lets users offload some or all of their weight while exercising. The treadmills can help people recover from athletic or brain injuries, and they allow a safe exercise regimen for others with long-term conditions such as arthritis.

Wireless Muscle Sensors

Some of the most exciting assistive technologies to spin off may be yet to come. Delsys Inc. developed electromyographic technology to help NASA understand the effects of long-term weightlessness on astronauts’ muscles and movements. Electromyography detects and analyzes electrical signals emitted when motor nerves trigger movement. Among the company’s customers are physical therapists developing exercise routines to help patients recover from injuries. But some researchers are using the technology to attempt recoveries that once seemed impossible, such as helping paralyzed patients regain movement, letting laryngectomy patients speak, and outfitting amputees with artificial limbs that work like the real thing.  

To further enhance the lives of people with disabilities, NASA has identified a selection of patented technologies created for space missions that could spur the next generation of assistive technology here on Earth.

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.

Wireless radiation could be used to surveil people without their knowledge or consent, even if they aren’t wearing a “smart” device or holding a cellphone, according to the authors of a new study.

The study authors — engineering faculty members with the Institute for Systems and Computer Engineering, Technology and Science at the University of Porto, Portugal — posted their report Jan. 24 on the Cornell University open-access research website, arXiv.

The study showcases hardware the authors designed that leveraged ambient wireless radiofrequency (RF) radiation to detect and render a visual image of human activity — such as waving a hand or a person’s breathing rate — with over 90% accuracy.

Their design involved a thin programmable surface — a Reconfigurable Intelligent Surface (RIS) — that communicates with computers and artificial intelligence (AI).

RIS can manipulate and steer Wi-Fi signals in controlled ways, explained Fariha Husain, manager of Children’s Health Defense’s (CHD) Electromagnetic Radiation (EMR) & Wireless Program. “By adjusting how radio waves reflect off this surface, the researchers were able to enhance signal-sensitivity and improve their ability to detect subtle human movements.”

Project Metamorphosis was the Space Pirates' way of preserving their commanders, keeping them alive through technology, and most importantly, keeping them operational; With cybernetics, any leader would be able to continue leading the Space Pirates in both tactics and even battle, no matter how damaged their organic bodies were.

Those submitted to the process were Space Pirate commanders injured by Samus Aran during her first assault on Zebes; Ridley, Kraid, and Weavel. Kraid was given a cybernetic dome over his face in order to protect his recovering eyes and see for them, but otherwise his adjustments were minimal. Ridley replaced a good portion of his body, and Weavel? He ended up replacing everything except his brain and spinal cord, much to his chagrin; His injuries were much more extensive, and unlike Ridley, he lacked any regenerative abilities.

But Project Metamorphosis was not just about giving Space Pirates cybernetic prosthetics; It went further than this. Hence, Mecha Ridley; At first glance, it seems to just be a robotic doppelganger of Ridley. And indeed, one of its functions was to act as a complete set of cybernetic prosthetics for the Space Pirate, meant to represent any possible limb or organ he might lose. This is quite common as a medical practice, although the full set of prostheses being programmed to attack intruders on their own isn't...

If Ridley were to lose an arm, an arm would be taken from the mecha and applied to Ridley's injured stump. If his face was burnt off, the skull chassis would act as a mask. Fire-breathing organs could be substituted with an internal flamethrower. The modular nature of Mecha Ridley meant that if Ridley replaced his hand, only to lose the rest of the arm it was connected to, the arm taken from his Mecha counterpart could still reconnect with the robotic hand he was currently using. In essence, Mecha Ridley was the precursor to the Meta and Proteus frames, hence the missile-launching booster as less a replacement and more an enhancement.

But Mecha Ridley had another function as well; Acting as a machine with which Ridley could project his own thoughts into, and control from afar. For in order to move the body, the brain sends signals through the nervous system, which the limbs and organs receive, and then interpret to move accordingly.

These signals are electric in nature; And so are wireless signals in technology. Through Project Metamorphosis, a neural interface could be applied to Ridley's head, and receive the signals he'd attempt to send to the rest of his body, replicating and redirecting them to his robotic doppelganger. Mecha Ridley would receive his brain's signals instead, and as a result its mimicry of Ridley's limbs would move, while his actual arms -if they were even present- would not do anything.

Mecha Ridley would also absorb visual and auditory input, directing it to Ridley, who would receive it via a VR headset. It's like a simulation, except your ‘avatar’ is in fact a tangible replica acting elsewhere. This feature is useful if Ridley or any other commander is so damaged that they can't even function on the field as a cyborg. In Ridley's particular case, it's to give his true body room to regenerate without having to worry about cybernetics restricting cellular repair, while also allowing him to fight 'on the field'. It's the best of both worlds.

...The problem with this form of cybernetic projection/possession is something every gamer fears; A bad connection. The Space Pirates worked to perfect the bandwidth of Ridley's neural headset and his mecha. But if Samus were to find herself unable to destroy a fully-completed Mecha Ridley, she could get around the problem entirely by interfering with the signals, causing the mecha to move one step behind Ridley, while Ridley received its input too late.

In case of this scenario, the Space Pirates programmed Mecha Ridley with its own independent AI to control itself with, should it stop receiving reliable input from Ridley in the heat of battle. So when Samus encountered it aboard the mothership, despite not being complete, Mecha Ridley still had a functioning AI to attack Samus with. Because this encounter happened so quickly after Ridley's defeat in Norfair, he hadn’t yet been resuscitated and hooked up to the neural interface. But in a future scenario, where Mecha Ridley was rebuilt and actually completed, it might've been something Ridley begrudgingly used while recovering from Phazon withdrawal and atrophy after the destruction of Phaaze.

Otherwise, he would avoid it if he could, and even subject himself to painful cybernetics as necessary; Ridley did not appreciate having a machine clumsily interpret his own moves for him. It was a distant, out of body experience, when Ridley preferred to fight in-person and experience death and destruction through his actual senses. Nevertheless, he kept the mecha on his personal ship; In Ridley’s off-time, he would put on the headset and test controlling the machine, so science team could see how to sync the mecha to his brain signals.

Since Project Metamorphosis could help Space Pirate commanders 'transcend the body', this same principle was applied to Meta Weavel. Despite Weavel being a Zebesian, his mechanical frame ended up having a noticeably different form, more upright and humanoid. The idea was to build off of Mecha Ridley by seeing how a brain could acclimate to a body very different to the one it was programmed to control. Hence the project’s name invoking the natural process of transformation and rebirth into something radically different; After a vulnerable workshopping period, of course.

Despite Weavel's frustrations over the differences, he did eventually adapt, and his Meta frame proved to be of sufficient quality. Thus, Meta Weavel would be deemed a success; It showed potential for brains to adapt to a wider variety of foreign shapes. So for example, a humanoid brain could be made to operate an arachnid body. Or a serpentine brain could now handle a body with several limbs, when such a brain wouldn’t even have neural pathways for this.

But the cybernetics could be made to interpret and ‘translate’ the brain’s signals, meant for a different body, into movements corresponding to limbs not alike. There have already been implants that translate the pheromones of species that communicate via smell into sound, and vice-versa, to aid in cross-species interaction; All of this is the natural extension, the natural evolution, of such technology. The Space Pirates would have to test more extreme examples like these, intensifying the disparity with each success.

And the goal was to combine these results with that of Mecha Ridley, to create technology in which a Space Pirate could telepathically control and 'possess' a mechanical body wildly different than their own. Project Metamorphosis would be taken even further from there; Perhaps being used to upload minds into machinery, allowing them to interface with data and become it, etc.

It could even lead to a telepathic possession and control of technology, with Mother Brain already being this; In fact, she helped form the inspiration for Mecha Ridley (so in a way, Zero Mission’s final boss is a culmination of Mother Brain, Ridley, and Weavel’s command). During her stint as Space Pirate leader, she permitted some study of her schematics by Project Metamorphosis scientists.

They analyzed Mother’s power to telepathically control both machines and even living organisms, in the hopes of replicating this with headsets and corresponding receivers; Science team hoped in particular to implant receivers into anyone or anything, without needing permission. Imagine hijacking a body by cutting off the signals from its host brain, so it would instead receive signals from another remote brain entirely.

Imagine bypassing the need to implant physical receivers entirely, and just using brainwaves and telepathy to disrupt a body’s natural signals and replace them at will! Imagine replacing them selectively to brainwash someone, letting them handle the rest as they obey and interpret on their own a basic command, freeing up brainpower to use in other processes or thralls!

All of this is how Mother Brain’s telepathic control works; It enabled her to control the Metroids, especially since she possessed Chozo DNA that the larvae were still programmed to obey. And it helped Mother Brain take command of technology as she saw fit, even sometimes controlling her Chozo charges for them so they could just let their minds and wills rest.

It allowed Mother to influence Zebes’ ecosystem and make it hostile to all outsiders. Her job has always been to do the thinking for people, after all; She is their new brain. Mecha Ridley is just the natural evolution of cybernetics interpreting for regular body parts the brain’s signals; Mother Brain’s conquest is just the natural evolution of her own programming, which she hijacked for herself to no longer be made to control, but to control under her own volition.

What is the mechanism behind RFID hotel key cards?

In the modern hospitality industry, enhancing guest experience and operational efficiency is a core goal for every hotel manager. With advancements in technology, RFID (Radio Frequency Identification) has become an essential tool in hotel management. Particularly in the application of hotel key cards, RFID technology has brought unprecedented transformations. RFID hotel key cards not only simplify the check-in and check-out processes but also provide enhanced security, significantly improving guest convenience and overall satisfaction. How does RFID technology make all this possible? What is its working principle? This is a common curiosity among hotel managers, and today, we will explore this topic.

1. The Working Principle of RFID Hotel Key Cards

Before delving into how RFID hotel key cards work, let’s briefly introduce what RFID technology is.

What is RFID Technology?

RFID technology facilitates the exchange of information between objects through radio waves. It employs a tag and a reader for contactless data transmission, eliminating the need for physical contact. Users can simply bring an RFID card close to the reading device, and data will automatically transfer to complete authorization, authentication, or operations.

RFID hotel key cards are a type of RFID tag that connects with the hotel lock system via an RFID reader installed on the door lock, enabling contactless identity authentication and unlocking functions. Each card contains a tiny embedded chip that can store encrypted data such as the guest's room number, validity period, and access permissions. When a guest approaches the door lock with their card, the RFID reader communicates with the card via electromagnetic waves, retrieves the stored information, and decides whether to unlock the door based on pre-set security rules.

How RFID Cards Interact with Hotel Lock Systems

The interaction between RFID cards and hotel lock systems is grounded in simple, efficient wireless communication. In this process, the embedded chip within the RFID card contains a unique ID number, which is decoded by the RFID reader upon receiving a signal. Here’s a breakdown of the specific workflow:

Signal Emission: When the RFID card nears the lock system, the RFID reader within the lock emits an electromagnetic signal, activating the chip in the card.

Data Transmission: The chip in the card transmits its stored ID information to the reader, which then compares this information against the hotel management system.

Authentication and Authorization: If the card information matches the records in the system and the access validation is successful, the door lock will unlock, granting the guest entrance to their room.

The contactless feature of RFID technology makes the hotel check-in process smoother and more convenient, as guests don’t have to insert the card or physically manipulate a key, significantly enhancing the overall fluidity and experience of entering the hotel room.

Additionally, RFID cards offer heightened security. Compared to traditional magnetic stripe cards, the data transmission of RFID cards employs more complex encryption algorithms, making it harder to copy or tamper with information, thus providing greater security for hotels.

Through this series of simple and efficient operations, RFID hotel key cards not only ensure guest convenience but also significantly enhance hotel operational efficiency and security.

2. Advantages of RFID Hotel Key Cards

The introduction of RFID hotel key cards offers significant advantages to hotels, enhancing not only security but also customer experience and operational efficiency.

Enhanced Security

RFID cards utilize encrypted data transmission and unique chip designs to prevent card information from being copied or hacked. They can also be configured with specific validity periods and access permissions, ensuring that rooms can only be accessed within authorized times, thereby reducing the risk of unauthorized entry. Many five-star hotels have effectively improved room security and protected customer privacy through such solutions.

Improved Customer Experience

RFID cards streamline the check-in and check-out processes, allowing guests to simply hold the card near their room door to unlock it automatically. This contactless operation not only enhances convenience but also reduces the risk of contact transmission, increasing guests' peace of mind.

Cost Savings in Operations

RFID technology aids hotels in automating management tasks related to rooms and keys, minimizing human errors and wasted time. The system can monitor card usage in real time, alerting staff to lost or unauthorized use of cards promptly, which improves management efficiency and lowers operational costs.

Increased Management Flexibility and Scalability

RFID technology can seamlessly integrate with other management systems, enabling hotels to expand functionality on demand, such as automated climate control or lock management. This flexibility allows hotels to respond quickly to changing demands and easily upgrade their systems.

Enhanced Brand Image and Customer Loyalty

The use of RFID cards boosts the technological appeal of the hotel, enhancing its brand image. Additionally, through RFID cards, hotels can offer personalized services, which helps increase customer loyalty.

In summary, RFID hotel key cards provide a range of advantages that contribute to a safer, more efficient, and more enjoyable experience for both guests and hotel staff. This technology is not just a trend but a valuable asset in modern hotel management.

3. Future Development of RFID Hotel Key Cards

As technology continues to advance, the application of RFID technology in the hotel industry is expected to become more widespread and intelligent.

Smarter Integrated Systems

Future RFID systems will be more tightly integrated with other intelligent systems within hotels, such as Internet of Things (IoT) devices, smart room controls, and Customer Relationship Management (CRM) systems. Through this integration, hotels can offer more personalized services, such as automatically adjusting room temperature, lighting, and other amenities based on guest preferences, thereby enhancing the customer experience and reducing energy consumption.

Enhanced Security and Encryption Technologies

As security requirements continue to grow, future RFID hotel key cards will employ more advanced encryption technologies to ensure the safety of guests' personal information and room security. With dynamic encryption and multi-factor authentication mechanisms, RFID cards will effectively defend against various cyber attacks and forgery attempts, further strengthening the security of hotel management.

Data Analytics and Personalized Services

RFID systems will evolve beyond being simple door lock management tools. In the future, they will integrate with data analytics tools to help hotels analyze guest behavior and preferences, thereby enabling more personalized services. For example, hotels could automatically push tailored offers and services based on guests’ check-in history and spending habits, enhancing customer engagement and loyalty.

In summary, the future of RFID hotel key cards promises to be more intelligent, secure, and personalized, transforming the hospitality experience and paving the way for a new era in hotel management. As these technologies develop, they will not only improve operational efficiency but also create a more satisfying experience for guests.

4. RFID Hotel Key Cards: The Key to Enhanced Hotel Management Efficiency and Customer Experience

Through contactless, efficient, and secure solutions, RFID hotel key cards not only provide guests with a more convenient and safe check-in experience but also enhance operational efficiency and reduce costs for hotels.

As technology continues to advance, RFID systems will become increasingly intelligent and integrated, with a stronger focus on security and data analytics functions. Whether through integration with smart room control systems or the fusion of mobile devices with RFID cards, future RFID technology will bring even more innovative opportunities to the hospitality industry.

Best Partner for Wireless Modules: A Comprehensive Antenna Selection Guide

n the field of wireless communication, antenna selection is crucial. It not only affects the coverage range and transmission quality of signals but also directly relates to the overall performance of the system. Among various wireless modules, finding the right antenna can maximize their potential, ensuring stable and efficient data transmission.

When designing wireless transceiver devices for RF systems, antenna design and selection are essential components. A high-quality antenna system can ensure optimal communication distances. Typically, the size of antennas of the same type is proportional to the wavelength of the RF signal; as signal strength increases, the number of required antennas also grows.

Antennae can be categorized as internal or external based on their installation location. Internal antennas are installed within the device, while external antennas are mounted outside.

In situations where space is limited or there are multiple frequency bands, antenna design becomes more complex. External antennas are usually standard products, allowing users to simply select the required frequency band without needing additional tuning, making them convenient and easy to use.

What are the main types of antennas?

External Antennas: These antennas can be classified into omnidirectional antennas and directional antennas based on the radiation pattern.

Internal Antennas: These antennas refer  to antennas that can be placed inside devices.

Omnidirectional Antennas: These antennas radiate signals uniformly in the horizontal plane, making them suitable for applications that require 360-degree coverage, such as home Wi-Fi routers and mobile devices.

Directional Antennas: These antennas have a high emission and reception strength in one or more specific directions, while the strength is minimal or zero in others. Directional antennas are primarily used to enhance signal strength and improve interference resistance.

PCB Antennas: These antennas are directly printed on the circuit board and are suitable for devices with limited space, commonly used in small wireless modules and IoT devices.

FPC Antennas: FPC antennas are flexible printed circuit antennas that are lightweight, efficient, and easy to integrate.

Concealed Antennas: Designed for aesthetic purposes, concealed antennas can be hidden within devices or disguised as other objects, making them suitable for applications where appearance is important without compromising signal quality.

Antenna Selection Guide

When selecting the appropriate antenna for a communication module, it's essential to first determine whether to use an internal or external antenna based on the module's structure.

External Antennas: These antennas offer high gain, are less affected by the environment, and can save development time, but they may take up space and impact the product's aesthetics.

Internal Antennas: These have relatively high gain and are installed within the device, maintaining a clean and appealing exterior.

 Sucker  Antennas: These provide high gain and are easy to install and secure.

Copper Rod  Sucker  Antennas: Made from large-diameter pure copper radiators, these are highly efficient with a wide bandwidth.

Rubber Rod Antennas: Offer moderate gain at a low cost.

Fiberglass Antennas: Suitable for harsh environments and ideal for long-distance signal

External Directional Antennas

Typically used in environments with long communication distances, small signal coverage areas, and high target density.

Panel Antennas have high efficiency, are compact, and easy to install, while considering the impact of gain and radiation area Yagi Antennas offer very high gain, are slightly larger, and have strong directionality, making them suitable for long-distance signal transmission; however, attention must be paid to the antenna's orientation during use

Internal Antenna Selection

Most internal antennas are affected by environmental factors and may require custom design or impedance matching

Spring Antennas are cost-effective but have low gain and narrow bandwidth, often requiring tuning for good matching when installed Ceramic Patch Antennas occupy minimal space and perform well, but have a narrow bandwidth
