James W. Griggs, III 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: 6622628
    Abstract: A smart igniter bus system has a repeater connected by a bus to a controller, and one or more smart igniters connected by the bus to the repeater so that the repeater is between the smart igniters and the controller. The repeater receives data transmitted on the bus by the controller and processes the signal sent by the controller with onboard logic. Utilizing the onboard logic, the repeaters are preprogrammed to rebroadcast control signals sent by the controller or to only rebroadcast selected signals, or to generate and transmit new command signals.
    Type: Grant

  • Patent number: 6588342
    Abstract: A frequency addressable ignitor control device utilizes electronic bandpass filters tuned to a unique center frequency and bandwidth for each ignitor. Energy generated by the system's controller comprises one or more narrow pulses whose center frequency corresponds to one or more bandpass filter/ignitor assemblies and sufficient energy for activation. A plurality of bandpass filter/ignitor assemblies are connected in parallel in the system. The controller generates electrical pulses of different frequencies transferred to the plurality of bandpass filter/ignitor assemblies via a two wire ignitor bus. Bandpass filter/ignitor assemblies whose filter allows sufficient energy to pass to an ignitor bridge element initiates the ignitor's explosive charge.
