The Keyence PX Series rugged photoelectric sensors from Keyence Corp. of America have been selected as NTB's Product of the Month for May. The sensors feature an IP-69K environmental rating for high pressure (1,400 psi) applications at temperatures to 176 degrees F. They feature stainless steel casings, sensor heads backfilled with epoxy under vacuum conditions, and scratch-resistant lenses. A dual-output feature enables users to see when the sensor activates and when the low-light alarm turns on.

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.
