Patents by Inventor Rick A. Lorenz

Rick A. Lorenz 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: 9000611
    Abstract: One embodiment of the present application is directed to a protection technique for an electric power generation system. In one or more implementations, an electric power generator, generator control circuitry, electrical output sensors to provide one or more corresponding signals, electrical switching equipment to selectively couple the generator to an electrical load, and electric power feeder or branch circuit conductors, to route electric power from the generator to the switching equipment, are provided. The control circuitry is responsive to the sensor signals to determine if a shutdown condition exists as a function of a protection profile determined for the system. This profile may account for damage thresholds of the generator, the feeder or branch circuit conductors, the electrical switching equipment for each of a number of different combinations of level and duration of electrical output as represented by the sensor signals.

  • Patent number: 7521822
    Abstract: One embodiment of the present application is directed to a protection technique for a back-up electric power generation system. This system includes an electric power generator, generator control circuitry, electrical output sensors to provide one or more corresponding signals, electrical switching equipment to selectively couple the generator to an electrical load, and electric power feeder conductors to route electric power from the generator to the switching equipment. The control circuitry is responsive to the sensor signals to determine if a shut-down condition exists as a function of a protection profile determined for the system. This profile may account for damage thresholds of the generator, the feeder conductors, and the electrical switching equipment for each of a number of different combinations of level and duration of electrical output as represented by the sensor signals.
