Patents by Inventor Rick L. Oppor

Rick L. Oppor 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: 9306561
    Abstract: A touch switch apparatus emulating a mechanical switch includes a field effect sensor and an electric field stimulator mechanically associated with the field effect sensor. A field generation signal applied to the field effect sensor causes an electric field to be generated thereabout. The electric field stimulator can be moved between first and second positions with respect to the field effect sensor. When moved into proximity with the field effect sensor, the electric field stimulator disturbs the electric field. A detection circuit coupled to the field effect sensor detects and responds to the disturbance to the electric field.

  • Patent number: 7364322
    Abstract: A lighting apparatus includes multiple point light sources housed in a reflector housing. The reflector housing diffuses the light produced by the point light sources to emulate a linear light source. Power supplies are provided to energize the light sources, to control heat generation and energy usage, and to provide thermal protection.

  • Patent number: 4983811
    Abstract: An auxiliary control system for an oven or similar device that is separate from the primary control circuitry and operates independently when the condition occurs that could be hazardous or unsafe. The control acts to prevent the temperature of a known point to rise above a predetermined set point, or points, and the primary circuitry failed to take corrective action.
