Abstract: An improved infrared occupant detection system that provides accurate and reliable occupant intrusion information at a speed sufficient to timely inhibit or otherwise control deployment of occupant restraints. An array of infrared emitters is selectively activated to emit a predetermined pattern of IR beams in an area between the passenger seat and the point of deployment of the restraint, and the reflected IR energy is detected by a photo-sensitive receiver and analyzed to determine whether an occupant is out of position for deployment of the restraint. In the preferred embodiment, the intensity of the received beam energy and the position of the respective beam are used to construct a table of individual intrusion factors, and a composite intrusion factor based on the individual intrusion factors is categorized by magnitude to form an indication of occupant intrusion level, which in turn, is used to determine whether, or how forcefully, to deploy the restraint in the event of a serious crash.

Abstract: A sensor including at least two active areas for receiving light energy and a resistive layer disposed on each of the at least two active areas for providing a pair of current signals corresponding to a position of light energy of a predetermined wavelength striking the active area. The two or more active areas are electrically isolated from each other and operate independent of each other. Preferably, the two or more active areas are electrically isolated with silicon dioxide.

Abstract: A user discrimination control system controls functionality made available by a vehicle infotainment device by reducing functionality provided to the driver while allowing enhanced functionality to another passenger in the vehicle. The system includes a human machine interface located in a vehicle for allowing an occupant to interface with the infotainment device. A passenger detection sensor senses a condition indicative of a passenger other than the driver interfacing with the human machine interface. A video imaging system detects a driver distraction condition. A controller controls functions made available by the infotainment device by allowing one of first and second levels of functionality based on the sensed conditions.
