Friedrich Von Der Luehe 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: 10509424
    Abstract: Disclosed is a switch device that includes or is formed by a switchgear. Two sensors of the switchgear monitor two measured values and a switch of the switchgear is switched depending on these measured values. The adjustable thresholds for the measured values are displayed on a digital display integrated in the switchgear or arranged on an external input device. Both thresholds are adjusted digitally via the input device. The input device can be a commercially available smartphone with an app or a laptop.
    Type: Grant

  • Patent number: 7865073
    Abstract: A heating module is provided for integrating into an electrical appliance, for example in a household appliance such as a coffee machine, or in a laboratory apparatus. Said module includes at least one heating surface formed from a body, at least one heating element that comprises at least one PTC element and is fixed in the body, and a flow heater that is integrated into the heating module. The heating module is configured to be easy to mount and have a wide range of applications. In one embodiment, the body is embodied as an extruded shape having at least one tube receiving element and a tube through which a fluid flows arranged on or in the tube receiving element.

  • Patent number: 7335855
    Abstract: An electric PCB heating component for a heating electric component is coupleable to an electronic circuit board. The PCB heating component includes a fastening element, a heating element for generating thermal energy, and a heating body. The heating body emits thermal energy via a heat radiating surface. For a low cost PCB heating component, the heating element is a PTC heating element. A plurality of heating projections of the heating element cooperate to form a relatively large heat radiating surface such that thermal energy can be emitted in a substantially directional mode. The heating projections can be convection or radiation elements.
