Raphael Bennes 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).

  • PTC heating device without electronic power control
    Patent number: 9210739
    Abstract: Foil-based PTC heaters are self-regulating, i.e. do not need any electronic control unit (ECU) to limit the maximum heating current. In order to establish different heating power levels the present invention proposes to choose different PTC ratio/onset characteristics. In addition, the print design of the PTC ink can be adjusted accordingly.

  • POLYMER THICK FILM DEVICE
    Publication number: 20150163862
    Abstract: A PTF (polymer thick film) device (10) comprises a substrate (22, 32), a functional PTF layer (24,34) applied on the substrate and a protective cover (25, 35) applied over the PTF layer, the protective cover being an adhesive tape comprising a carrier layer (27, 37) and a layer of adhesive (26, 36), the carrier layer being coated with the layer of adhesive (26, 36), the layer of adhesive (26,36) having a thickness comprised in the range from 10% to 100% of the print thickness of the PTF layer (24, 34). The PTF layer is a carbon ink layer, a silver ink layer, a graphite ink layer, a carbon-silver ink layer, a carbon-graphite ink layer, a graphite-silver ink layer, a carbon-graphite-silver ink layer or a PTC layer (Positive Temperature Coefficient). The PTF device can be used as an electric heater, e.g for car seats.

  • SHEET-TYPE OHMIC HEATING ELEMENT
    Publication number: 20140326709
    Abstract: A sheet-type ohmic heating element (10) comprises a substrate sheet (12) having applied thereon a layer of PTC material (14) and a protective cover sheet (16) laid over the layer of PTC material. The protective cover sheet extends beyond the boundary of the layer of PTC material and is affixed to the substrate sheet circumferentially around the boundary of the layer of PTC material. The protective cover sheet and the layer of PTC material are arranged in non-adhesive contact with each other.
