Vehicle object detection system and method

摘要: System for obtaining information about an object in the vehicle including one or more resonators reflectors arranged association with object, each resonator emitting energy signal upon receipt of a at excitation frequency, transmitter device transmitting signals least frequency resonator, detector detecting emitted by and processor coupled to analysis detected detector. The obtained may be distance between detector, which positional is useful controlling components such as occupant restraint protection device. If seat, seat indication position back cushion bottom angular orientation other parameters. resonator(s) within SAW device, antenna and/or RFID tag. When several are used, designed emit different frequency. tuned acoustic cavity vibrating mechanical element.
