A driver's head position sensor is used to control deployment of safety airbags in a vehicle. An array of thermal imaging detectors provides a thermal image of a driver and detects both his head and position of his head relative to the airbags. Movement of the head towards the airbags, for example during manual operation of a radio, is measured and used to control the amount of airbag deployment. The detector array may be a 32 by 32 or 64 by 64 array of detectors such as microbridge resistance bolometer detectors. |
