Software called Micropilot may help researchers struggling to pinpoint particular cells in their microscopes. The technology, developed by European Molecular Biology Laboratory (EMBL) scientists, searches for cells with specific features. After detecting the cells that a researcher is interested in, the...

This week's Question focuses on a new service from T-Mobile that, for just 4.99 a month, automatically disables rings and messages, and sends calls to voicemail when the phone is in a moving car. The services being tested and deployed are voluntary and can be overridden if a driver...

Fuel cells use the chemical energy of hydrogen or other fuels to efficiently produce electricity or heat with minimal byproducts, primarily water. The DOE is accepting applications for a total of up to $74 million to support the research and development of clean, reliable fuel cells for...

Researchers from Northwestern University and the University of Illinois at Urbana-Champaign have developed a nickel-size, curvilinear camera with a 3.5x optical zoom. Or, to put it simply, an eyeball camera. The lens and photodetectors are on flexible substrates. A hydraulic system then changes the shape of the substrates, allowing the...

This week's question addresses last week's news that Verizon will soon sell the iPhone 4. Although some analysts say the move may double Apple's market share, many enterprises and financial institutions have held back on the mobile device due to concerns of its...

The 2010 Create the Future Design Contest, sponsored by COMSOL, Inc., PTC, and Tech Briefs Media Group (publishers of NASA Tech Briefs), recognized innovation in product design in six categories: Consumer Products, Machinery & Equipment, Medical, Safety & Security, Sustainable Technologies, and...

Photoelectrochemical cells convert sunlight into electricity, but their light-absorbing dyes, called chromophores, eventually degrade because of sunlight exposure. For plant cells, the degradation of chromophores isn't a big deal - they simply self-regenerate. Now, Purdue researchers are in the early stages of creating a...

A Distributed Aerodynamic Sensing and Processing (DASP) toolbox was designed and fabricated for flight test applications with an Aerostructures Test Wing (ATW) mounted under the fuselage of an F-15B on the Flight Test Fixture (FTF). DASP monitors and processes the aerodynamics with the...

Intelligent sensor technology and systems are increasingly becoming attractive means to serve as frameworks for intelligent rocket test facilities with embedded intelligent sensor elements, distributed data acquisition elements, and onboard data acquisition elements....

The Autonomous Landing and Hazard Avoidance Technology (ALHAT) Project is developing a system for safe and precise manned lunar landing that involves novel sensors, but also specific algorithms. ALHAT has selected imaging LIDAR (light detection and ranging) as the sensing modality for onboard hazard...

Collaboration methods for distributed machine-learning algorithms involve the specification of communication protocols for the learners, which can query other learners and/or broadcast their findings preemptively. Each learner incorporates information from its neighbors into its own training...

A method detects and isolates in-flight sensor, actuator, and component faults for advanced propulsion systems. In sharp contrast to many conventional methods, which deal with either sensor fault or component fault, but not both, this method considers sensor fault,...

A wireless avionics interface provides a mechanism for managing multiple broadcast transceivers. This interface isolates the control logic required to support multiple transceivers so that the flight application does not have to manage wireless transceivers. All of the logic...

A sequencer for a radar altimeter provides accurate attitude information for a reliable soft landing of the Mars Science Laboratory (MSL). This is a field-programmable-gate-array (FPGA)-only implementation. A table loaded externally into the FPGA controls timing, processing, and decision structures....

High precision SAD5 stereo computations can be performed in an FPGA (field-programmable gate array) at much higher speeds than possible in a conventional CPU (central processing unit), but this uses large amounts of FPGA resources that scale with image size. Of the two key resources in an FPGA,...

A room temperature sapphire acoustics resonator incorporated into an oscillator represents a possible opportunity to improve on quartz ultrastable oscillator (USO) performance, which has been a staple for NASA missions since the inception of spaceflight. Where quartz technology is very mature and shows...
