Richard L. Piekarz 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: 10680547
    Abstract: The disclosed examples provide an easy and low-loss solution to reduce voltage stress on motor and cable in inverter-fed motor systems by suppressing resonances on the motor cable with apparatus coupled between the inverter output and the motor cable. Disclosed examples include various methods to mitigate voltage stress on both motor and cable, including an output filter circuit with a cable side parallel RL circuit between an inverter output and a motor cable, and an inverter to provide an inverter output signal to the output filter circuit to drive a load through the motor cable, where the cable side parallel RL circuit includes a resistor coupled in series between the inverter output and the motor cable, and an inductor connected in parallel with the resistor.

  • Publication number: 20090325156
    Abstract: The invention provides methods and materials for screening for polymorphic variants in ABCB1 and diagnosing altered susceptibilities for drug-induced heart rhythm irregularities based on the same. These methods allow better treatment regimens for using drugs that bind a protein encoded by the ABCB1 and/or induce heart rhythm irregularities such as the anti-cancer drug FK228.
