Patents by Inventor JAN ROBIN FISCHER

JAN ROBIN FISCHER 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).

  • Sensor for detecting immersion in F.O.G. or water
    Patent number: 10830718
    Abstract: An apparatus for discriminating between liquids having differing thermal conductivities includes a thermally conductive substrate, a resistor and a thermistor mounted to the thermally conductive substrate. Two leads on the resistor enable a current to be passed through the resistor to generate heat, and two leads on the thermistor enable a current to be passed through the thermistor to generate a datum indicative of thermistor temperature. An electrical insulator encapsulates the resistor, the thermistor and part of the thermally conductive substrate. A remainder of the thermally conductive substrate may extend beyond the electrical insulator to provide a thermal path from the resistor and thermistor to a liquid in which the apparatus may be immersed.
