Patent number: 8525648Abstract: A backscatter passive wireless control system and method employs frequency coding using frequency components generated from an interrogating field using a passive nonlinear element such as a diode in a passive transponder tag. In particular, InterModulation Distortion (IMD) frequency components may be generated which are shifted in frequency from the interrogating signal to assist in backscatter detection at a receiver but are still in band, e.g., in an ISM band. The shifted frequency components may be swept or stepped over a range and passive elements in the tag encode a tag ID by selecting specific frequencies to be backscattered. A manually operated switch may couple an antenna to the transponder to allow battery free control.Type: GrantFiled: June 24, 2009Date of Patent: September 3, 2013Assignee: Ezero Technologies LLCInventor: David L.
