Acceleration Sensors for Airbags
A family of intelligent acceleration sensors for front and side crash detection in advanced airbag systems has been developed by Freescale Semiconductors.
A family of intelligent acceleration sensors for front and side crash detection in advanced airbag systems has been developed by Freescale Semiconductors. The Xtrinsic MMA65xxKW family of accelerometers is designed to be integrated into a vehicle’s electronic control unit (ECU) as main crash sensors. They’re based on high-aspect-ratio micro-electromechanical systems (HARMEMS), which offer better precision and a wider dynamic range compared to current sensors, which means enhanced performance. The sensors are expected to enter production in Q2 2012.

Ram Truck chief exterior designer Joe Dehner talks about how they’ve developed the all-new pickup. “We’ve been building trucks for over 100 years,” he says. “Best I could come up with is that this is our 15th-generation truck.”
This is not a piece of modern art: Rather, it is an image from Blackmore Sensors and Analytics of Bozeman, Montana, micro-Doppler signatures of pedestrians (or maybe that’s a pedestrian, singular) walking (see it now?). Blackmore is a company that is developing FMCW lidar.
