Boosting Energy Efficiency of Multi-Hop Wireless Networks
Posted in Batteries, Power Management, Energy Efficiency, Communications, Wireless, News on Wednesday, 25 April 2012
Multi-hop wireless networks can provide data access for large and unconventional spaces, but they face significant limits on the amount of data they can transmit. North Carolina State University researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.

Transient Voltage Suppressor Arrays
Posted in Power Management, Products, MDB on Sunday, 01 April 2012
Microsemi (Aliso Viejo, CA) has introduced two new non-magnetic, 500-watt transient voltage suppressor (TVS) arrays. The devices were designed specifically for MRI machines to guard against circuit damage caused by electrostatic discharge, electrical fast transients, and the effects of secondary lighting. The USBQNM504xx and USBQNM504xxC TVS arrays protect uni- and bi-directional lines, respectively. They are offered in a non-ferrous, quad flat no-lead 143- pin metal lead frame. Additional features include peak power rating of 500 watts for an 8/20 microsecond pulse and protection against electrostatic discharge (ESD).
