Abstract:
A method of detecting one or more objects including an occupant of a vehicle and identifiable parts of the occupant, comprising the steps of:a) transmitting a first pulse having a determinable signature in the direction of an occupant;b) establishing a received signal threshold;c) sensing a received signal reflected from an object including a received signal reflected from the targeted occupant;d) determining when the amplitude of the received signal exceeds the threshold and storing numbered time increments during which the received signal exceeds the threshold;e) evaluating the stored increments and grouping contemporaneous increments together, each group of increments being indicative of one target which reflected the first pulse;f) determining a first group of increments, from those grouped in step e, corresponding to the highest numbered increments and correlating same with the position of the torso of the occupant.
