Reports: Lumedyne Technologies Acquired By Google

San Diego-based Lumedyne Technologies, a developer of MEMs-based, inertial direction sensors, has quietly been acquired by Google, according to multiple reports. The deal reportedly happened in November, and was worth $85M. Neither Google nor Lumedyne Technologies have announced or acknowledged the deal. Lumedyne's sensors are being used for very fine tracking of direction changes, using a method called Time Domain Switched (TDS) sensing. The company had been aiming that technique at indoor cell phone navigation, military navigation and sensing in satellites and airplanes, as well as other areas. The company was founded by Brad Chisum and Dr. Richard Waters.
