Patents by Inventor William Jeffreys

William Jeffreys 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).

  • Patent number: 8266577
    Abstract: A radio frequency identification (“RFID”) reader includes a hardware platform having a transceiver, an input/output interface, a controller, and a memory. The transceiver receives communication signals from at least one RFID tag. The controller is communicatively coupled to the transceiver and the input/output interface and controls the operation of the RFID reader. The memory is communicatively coupled to the controller and contains a software development framework for developing a software application. The framework includes a plurality of predefined encapsulated functional components that interact with at least one of the transceiver and the input/output interface, to allow the software application to operate in a manner that is independent of a specific embodiment of the RFID reader hardware platform.
    Type: Grant

  • Patent number: 6862719
    Abstract: Automatic tuning of an EAS antenna pedestal without the use of special tools or advanced training is provided. The capacitance of the antenna circuit is adjusted to tune the resonant frequency to the desired frequency. Measurement of the current level is used to validate that the antenna is resonant at the desired frequency. If the current level indicates that the antenna is not resonant at the specified frequency, LEDs located on a capacitor tuning board light to indicate where jumpers should be placed to add or remove capacitance from the circuit. Alternately, the capacitance values can be electronically added or removed from the circuit.
