Patents by Inventor Perry B. Peden

Perry B. Peden 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).

  • Methods and systems for automated pipeline testing
    Patent number: 7068052
    Abstract: A method for testing a cathodic protection system is disclosed where the system includes a cathodic protection rectifier configured to apply a voltage across a pipeline and a reference point. The method includes measuring a magnitude of an output voltage of the cathodic protection rectifier, transmitting to a site remote from the rectifier, the measured output voltage magnitude using a cellular control channel, receiving the transmitted measurement at the remote site, and using the transmitted measurement to determine whether the cathodic protection system is operational.
    Type: Grant
    Filed: June 22, 2004
    Date of Patent: June 27, 2006
    Assignee: NTG, Inc.
    Inventors: Thomas N. Hilleary, Perry B. Peden, Jr.

  • 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.
