Exclusive Interview With the Director of 'Westinghouse'

Westinghouse is a fascinating new feature-length documentary about the life and times of George Westinghouse, one of America's greatest inventors, entrepreneurs, and industrialists. Listen to our interview with the writer and director, Mark Bussler, as he discusses this "forgotten giant" -- his amazing legacy, greatest inventions, and competition with Thomas Edison, which culminated in the Battle of the Currents at the Chicago World's Fair and set the stage for the entire future of electric power.

Hand-Held Units for Short-Range Wireless Biotelemetry

These units would power surgically implanted sensors. Special-purpose hand-held radio- transceiver units have been proposed as means of short-range radio powering and interrogation of surgically implanted microelectromechanical sensors and actuators. These units are based partly on the same principles as those of the units described in “Printed Multi-Turn Loop Antennas for RF Biotelemetry” (LEW-17879-1), NASA Tech Briefs, Vol. 31, No. 6 (June 2007), page 48. Like the previously reported units, these units would make it unnecessary to have wire connections between the implanted devices and the external equipment used to activate and interrogate them.

Wearable Wireless Telemetry System for Implantable BioMEMS Sensors

Physiological monitoring would entail minimal risk, discomfort, or restriction of mobility. Telemetry systems of a type that have been proposed for the monitoring of physiological functions in humans would include the following subsystems: Surgically implanted or ingested units that would comprise combinations of microelectromechanical systems (MEMS)- based sensors [bioMEMS sensors] and passive radio-frequency (RF) readout circuits that would include miniature loop antennas. Compact radio transceiver units integrated into external garments for wirelessly powering and interrogating the implanted or ingested units.

Electronic Escape Trails for Firefighters

Routes would be traced among RFID tags equipped with sensors showing temperatures. A proposed wireless- communication and data-processing system would exploit recent advances in radio- frequency identification devices (RFIDs) and software to establish information lifelines between firefighters in a burning building and a fire chief at a control station near but outside the building. The system would enable identification of trails that firefighters and others could follow to escape from the building, including identification of new trails should previously established trails become blocked.

Deployable Wireless Camera Penetrators

Disposable, wireless camera darts can be used in zero G, or for surface surveys. A lightweight, low-power camera dart has been designed and tested for context imaging of sampling sites and ground surveys from an aerobot or an orbiting spacecraft in a microgravity environment. The camera penetrators also can be used to image any line-of-sight surface, such as cliff walls, that is difficult to access.
