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...

As a result of performing IV&V (Independent Verification and Validation) on Space Station software, a number of interface faults were found during integrated testing or actual software deployment. Faults found at this late phase of the software development lifecycle are very expensive to...

Simple, Scalable, Script-based, Science Processing (S4P) Archive (S4PA) is a disk-based data-archiving system for remote sensing data. It is based on the data-driven framework of S4P. The system is used for new data transfer, data preprocessing, metadata generation, and data archival. The...

The Planetary Data System (PDS) has undertaken an effort to overhaul the PDS data architecture (e.g., data model, data structures, data dictionary, etc.) and deploy a software system (online data services, distributed data catalog, etc.) that fully embraces the PDS federation as an integrated...

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 at MIT and Northeastern University have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port.The sensor is an adaptation of a technology called GelSight, which was developed by the lab of Edward Adelson, the...

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...

Speed and agility are hallmarks of the cheetah: The big predator is the fastest land animal on Earth, able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop.Now MIT researchers have developed an algorithm for...

A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy.The device is called a transparent luminescent solar concentrator and can be used on buildings, cell phones, and any other device that has a clear...

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...

Short block codes are in demand by international space agencies for transmission of command and control data to spacecraft in the uplink channel. Codes that outperform currently used binary codes with the same block lengths and code rates are desirable. A design method constructs...

A method has been developed for resolving algebraic loops that occur in closed-loop systems when using MathWorks Simulink modeling and simulation tools. This variable fidelity method improves accuracy and reduces runtime significantly for users of Simulink Coder...
