Vehicle Passenger Detection System

Abstract

A passenger transport system comprising at least one electromechanical self-powering RF signal generator having a push & return mechanism, and at least one passenger seat having a seat region, wherein said push & return mechanism is installed, said generator, which is provided with an RF transmitter, is equipped to self-generate electric power based on a mechanical force applied on the push & return mechanism by a passenger sitting in the seat region, and whereby said generated electric power is used for the RF transmitter to transmit an RF signal on an adjustable frequency in case the passenger sitting in the seat region thereby presses a switch of the push & return mechanism, and which passenger transport system further comprises: a central RF receiver for receiving transmitted RF signals which have features to identify the individual passenger seats he RF signals are transmitted from, and means for based on the received RF signals deriving information indicating which of the passenger seats are and/or are not occupied.
