Ohio State University researchers report that they have succeeded in combining a battery and a solar cell into one hybrid device.Key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode....

The autonomous self-healing (eDNA) hardware platform is a reconfigurable field-programmable gate-array (FPGA)-type platform developed by Technical University of Denmark (patent: WO/2010/060923). It is capable of autonomously reconfiguring itself in case a fault is detected...

GPS receivers must compensate for the delay a GPS signal experiences as it passes through the ionosphere in order to accurately determine the position of the receiver. Receivers limited to terrestrial operation may utilize the Klobuchar parameters transmitted by...

Wafer-level integration was employed to mount the microshutter array for the James Webb Space Telescope (JWST) and the detector-read-out hybrid for TIRS (Thermal Infrared Sensor). In the case of the JWST substrate, two conductors (polysilicon and aluminum) separated by a silicon oxide...

A concept was developed for a multi-gigabit-rate, radiation-hardened (RH) bus that would support open-system architecture and provide a cost-effective, high-speed interconnect. This concept is based on Advanced Science and Novel Technology Company’s SerDes system, which supports a variety of interfaces, and...

New York, NY – Contour Crafting, a computerized construction method that rapidly 3D prints large-scale structures directly from architectural CAD models, has been awarded the grand prize of $20,000 in the 2014 "Create the Future" Design Contest. Contour Crafting...

Researchers from North Carolina State University have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable electronic circuits, antennas and other technologies. The technique hinges on the...

Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. A team of engineers at the University of California, San Diego, are trying to accomplish just that, in partnership with a local San Diego...

ZONE (Zeroing Out Negative Effects) is a method of biofeedback training for optimal athletic performance. ZONE is designed to improve athletes’ responses to stress, anxiety, and loss of concentration during competition. In the training environment, when the user successfully attains an optimal...

In high-integrity systems, a method of assuring integrity called a self-checking pair is employed. A self-checking pair is a logical grouping of two of the same devices performing the same operation and cross-checking each other to ensure correct operation. In this manner, a...

The system and method of reconfigurable Auditory-Visual Display creates a multi-mode communications environment with the express intent of increasing situational awareness for the operator (controller), and for reducing operator fatigue. Situational awareness is increased by a...

In this innovation, a method makes use of a new technique for describing analog information based on the roots of polynomial functions of infinite degree. Monotonic analog signals are transformed into characters that are fused into a two-dimensional composite visualization of the generating signal...

A fast Fourier transform (FFT) was developed as part of the Soil-Moisture Active/Passive (SMAP) project. The FFT was created on 16-bit data arriving at a rate of 48 MHz to run on a resource-constrained, space-grade field programmable gate array (FPGA).

An Integrated Modular Avionics (IMA) architecture provides a common platform for software partitions with shared processing and input/output (I/O) resources. A key feature of the IMA architecture is I/O partitioning. An IMA system will prevent one...

Smart sensors for measuring temperature and pressure have been developed as part of the Advanced Ground Systems Maintenance (AGSM) project. The sensors have flash memory for storing firmware, calibration data, and configuration information....

An updated software model has been developed for predicting the single-event effect (SEE) rates in circuit designs as they are being designed. This tool will be used for estimating the frequency of the various SEEs, such as logic upsets and circuit latch-up. It may also be used to estimate the total...
