Consumer shopping path pattern shopping trolley mounted position detection system having transmitter periodically sending signal and receiver time stamping and information processor transmitting information

摘要

The moving object positioning system has transmitters (2) which are activated periodically and a receiver unit (3) on the moving object, for instance a shopping trolley. The position of each receiver is determined from the time at which the transmit signal is received, and the position information passed by radio transmitter to a central location (6) for information processing.
