Patents by Inventor Fred Garber

Fred Garber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Uncontrolled passive radio frequency identification tag and system with 3-D positioning
    Patent number: 7988055
    Abstract: Passive radio frequency identification tags comprising a simple antenna and a circuit with a unique frequency-dependent response, in place of an RF-powered integrated circuit with control logic, is disclosed. The unique frequency-dependence of the circuit, which may simply be a feature of the antenna, conveys the tags identification. Multiple frequency-dependent circuit RFID tags can be simultaneously identified and located in 3-D space through use of antenna arrays and sampling at multiple frequencies in order to provide spatial resolution.
    Type: Grant
