Summary:
Penn State engineers have shown that broadband, wireless, indoor, local area communication networks that rely on non-line-of-sight infrared (IR) signal transmission can offer low error rates as well as safe, low – below one Watt – power levels.

University Park, Pa. --- Penn State engineers have shown that broadband, wireless, indoor, local area communication networks that rely on non-line-of-sight infrared (IR) signal transmission can offer low error rates as well as safe, low – below one Watt – power levels. Dr. Mohsen Kavehrad, professor of electrical engineering and holder of the W. L. Weiss (AMERITECH) chair, says, "Line-of-sight or point-to-point infrared signal transmission, which is used, for example, in television remote controls, is highly efficient at low power levels but suffers from the need for alignment between the transmitter and receiver. If someone ‘shadows' or blocks the remote control beam while you're trying to change the channel, the signal can't get through.

Porsche CEO Says Supercar Is Not Dead: Cue the Spyder 918

TheStreet (Apr. 16, 2014) The Porsche Spyder 918 proves that, in an automotive world obsessed with fuel efficiency, the supercar is not dead. Porsche North America CEO Detlev von Platen attributes the brand's consistent sales growth -- 21% in 2013 -- with an investment in new technology and expanded performance dynamics. The hybrid Spyder 918 has 887 horsepower and 944 lb-ft of torque, but it can run 18 miles on just an electric charge. The $845,000 vehicle is not a consumer-targeted vehicle but a brand statement.
