Albert F. Conard 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).

  • Ground fault interrupt analyzer method and apparatus
    Patent number: 6734680
    Abstract: A method and apparatus for testing whether a particular outlet is connected to a particular GFCI, which eliminates the need for having the electrical network turned on.
    Type: Grant

    Date of Patent: May 11, 2004
    Inventor: Albert F. Conard
  • Low voltage switching circuit for controlling a high voltage electrical load
    Patent number: 4360740
    Abstract: Solid state high voltage electronic switching means, preferably a triac, is connected in series with a high voltage load, for instance, a light, across a high voltage alternating current power source. Contacts of a relay having a low voltage coil are operably connected for controlling the triac. A diode and solid state voltage limiting and storage means, preferably a zenier diode, are also connected in series across the high voltage alternating current power source converting alternating current to direct current and reducing and storing the now direct current providing a low voltage direct current power source. A capacitor may be connected in parallel with the zenier diode for aiding in storing and stabilizing the low voltage direct current.
