Patents by Inventor Larry Klusman

Larry Klusman 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).

  • Method and apparatus for measuring the voltage and charge of a battery
    Patent number: 5315253
    Abstract: Method and apparatus for measuring the voltage and state of charge of a secondary battery. The voltage and state of charge values are taken by a circuit every four (4) seconds by reading voltage, waiting two (2) seconds, reading current, waiting two (2) seconds, and repeating the voltage readings and the current readings. The circuit includes a 4-bit microprocessor, CMOS analog switches, and two operational amplifiers. The voltage and current readings are taken from dual-sloped converters, and the values determined by software algorithms in the microprocessor.
    Type: Grant
    Filed: August 28, 1992
    Date of Patent: May 24, 1994
    Assignee: Alexander Manufacturing Company
    Inventors: Richard B. Alexandres, Dennis P. Kindschuh, Larry Hall, Perry B. Peden, Larry Klusman, Steve Potratz
