Boeing: New Enclosure ‘Keeps Us From Ever Having a Fire’

By Charles Murray – The Boeing Co. took the issue of 787 battery fires head-on last night, definitively declaring that with pending modifications to its lithium-ion battery packs, a “fire can’t begin, develop, or be sustained.”

The key to preventing fires is to carefully control the amount of available oxygen, Mike Sinnett, vice president and chief engineer of the 787 program said. Describing a potential scenario, he explained that the pressure disc in the rear of the enclosure would open after about 1.5 seconds of cell venting. Vented electrolyte would then entrain the air inside the enclosure and “take it overboard… So as long as we keep the vented air out of the battery enclosure, there’s no oxygen to support combustion.” more> http://tinyurl.com/cp5q43s

Military Radar Comes to Home Security Market

By Kristin Lewotsky – The SPEXER 1000 brings military-class performance to security applications, allowing facilities to monitor a 120° field of view economically across a range as long as 17km (10.6 miles). The complete system is designed for easy installation and integration with command and control systems on stationary and mobile platforms monitoring land, sea, or air.

Conventional radar systems often rotate to cover 360°, but that’s not always necessary in security applications. Often, perimeters can be secured by monitoring specific areas of vulnerability, which speeds up the process while reducing power demand and avoiding the acquisition and processing of unnecessary data. An airport system, for example, could ignore passenger entry points but would need to cover regions at the ends of runways or around the fuel depot. more> http://tinyurl.com/cfwg9xc

Failure Is Not An Option
