Latest Patents
His latest patents include a system for the detection of multiple articles. This identification system comprises an interrogator and a plurality of transponders. The interrogator features a transmitter that transmits at least two independent interrogation signals to the transponders, along with a receiver for receiving response signals from them. The system also includes processor means for identifying the transponders based on data in the received response signals. Each transponder is equipped with receiving means, a code generator, and transmitter means connected to the code generator. Upon receiving at least one of the transmitted interrogation signals, the transponder sends a response signal containing identifying data. The interrogation signals can be transmitted continuously or intermittently, and in a preferred embodiment, they are narrow bandwidth signals at different frequencies. The receiving means of each transponder has a broad reception bandwidth, allowing it to respond to one or more of the interrogation signals.
