NASA’s Langley Research Center researchers have developed a measurement acquisition system that uses magnetic fields to provide power to sensors and to acquire physical property measurements from them. Unlike traditional acquisition devices, this system has the ability to make multiple measurements of different, non-related physical properties without the constraint of a limited number of data acquisition channels. Winner of the prestigious R&D 100 award, this technology has been demonstrated with a leading aircraft landing gear manufacturer to wirelessly measure the fluid levels in landing gear shock struts. In addition to fluid level, rotation, temperature, material phase changes, proximity, position, and volume measurements have all been demonstrated.

This measurement acquisition device uses magnetic fields to power and interrogate passive inductor-capacitor ...

The device consists of a wireless-type battery charger, compatible with the interface of most mobile devices (cell phone, Tablet), with a mechanical platform to control the distance between charger and device to give an optimal electrical current flow. The MWC provides a special device that avoids damaging current values in the charger for continuous use of the system. Wireless charger replaces the need to charge the phone via a socket electrical bonding to the wall.

Current wireless Chargers devices require that the charging device has a compatible charger receiver element. Initially, only phones made since 2013 have wireless loading devices. The benefit is then for those devices manufactured before this date, which will have access to the benefits that ...

In the present day scenario, Agriculture uses 85% of fresh water resources and this percentage will increase in the future years. Hence the water and food demand should be met by the recent technologies for sustainable use of water. The proposed method is based on an irrigation control system to optimize the water use for agriculture. Irrigation control system that consists of a distributed wireless network of soil moisture and temperature sensors deployed in plant root zones. Each sensor node involved a humidity sensor probe, a temperature sensor, a microcontroller for data acquisition, and a radio transceiver. The sensor measurements are transmitted to a microcontroller-based receiver. This gateway permits the automated activation of irrigation when the threshold values humidity ...

Flexible field effect transistors (FET) reported till date contains polymers like PDMS (Poly-dimethyl siloxane) or PS (Polystyrene) as substrate or gate material. This possess serious limitations in terms of their fabrication procedure, repeatability, bio-degradability, bending and long-term aging response. In this work, we have conducted one pot fabrication of solution processed FET on paper substrate without use of any additional polymer for substrate or gate dielectric for the first ever time. Filter paper with adsorbed ionic liquid (1-butyl-3-methyimidazolium octylsulphate), silver nanoparticles (AgNP) and reduced graphene oxide (rGO) were used as substrate as well as the gate material for three different fabricated FETs. Pencil markings on these substrates acted as the channel for fabricated FETs. Metallic silver paint painted on ...

The National Aeronautics and Space Administration (NASA) seeks partners interested in the commercial application of the Polyimide Wire Insulation Repair System technology. NASAs Kennedy Space Center is offering companies licensing for this innovative wire repair technology.

The Polyimide Wire Insulation Repair System is a kit consisting of thin film polyimide patches, which are applied to damaged areas of wire insulation that have been damaged, along with a heating device that adheres the polyimide repair film into place. The technology has been prototyped and successfully tested by NASA and the Naval Air Systems Command (NAVAIR). Wire repairs made with this system are permanent, flexible, and much less intrusive than repairs made using current techniques and materials. The technology is well ...

Enthusiasts and Hobbyists generally while working with electronics face a common problem to test their circuit designs, which is getting a right power source which could power their system.

And we try to get batteries and try to combine them to get the right supply, but still we rarely get a combination of battery for most digital logic supply like 5v, 3.3v or 1.8v etc.

Sometimes we need supply like 12v also for running some high power electronics or may be just to run an old opamp.

But getting a bulky, bench-top power supply is not possible for everyone, because first of all they are costly not in average hobbyists budget most of the times, and also that they ...

People who travel for business often have the need to send and receive fax documents when away from the office. “Fax by email” services may satisfy this need in some locations, but the hazards of finding an appropriate Internet signal make this solution unsatisfactory in many places. Privacy is too often an issue (doing business at Starbucks, anyone?), and one never knows who might be snooping on the signals. Another solution would be to find a Kinko’s store or other public service facility, which can be a problem, especially late at night. Many business-oriented hotels have a communications room available for use – which may be fine if you can find an open desk and don’t mind doing your ...

The Internet of Things (IoT) promises a world in which everything is connected by sensors to everything. The cost and logistics associated with installed wiring or using batteries to power these systems represent a significant cost. Our proprietary SemperCell technology, harvests or scavenges environmental energy and converts this energy to stored electrical power and eliminates the need for expensive wiring and battery changes. This greatly reduces customer operational costs. Our technology enables industrial clients to monitor their assets utilizing this new capability. There is a need to power these billions of sensors. Traditional methods are impractical due to the cost. Our state of the art technology solves this problem.

We have spent the last three years developing proprietary knowledge ...

Pre-assembled hermetic chip carrier for MMIC or ASIC or general purpose chips silicon base or quartz or other type electronic circuit chips.The advantage is that the chip carrier design is pre wired with lead wires pre bonded to the chip carrier itself that contact the pads of the chip itself when inserted.The fully pre assembled chip carrier is designed to be hermetically sealed after chip installed and the base applied.To use one simply unpacks the chip carrier then places the chip inside with the correct orientation then places the other half of the chip carrier on and close together the two halfs both the top and the bottom half and then socket tests the Assembly for chip performance for ...
