ABSTRACT:
This invention relates to resonant LC responders that are placed inside objects such as toys. The device includes an interrogation or base unit which sends a pulse and passive responders which reply with their unique frequency which is sensed by the base unit. The base unit senses the frequency and triggers a response in the play pattern of the object such as speaking or turning on a motor. The invention can discriminate multiple responders based on their frequency or location. Further, the device can interface with active responders as well. The invention provides a low cost, simple device to provide recognition particularly at a distance in interactive toys.
