Patents by Inventor Daniel James Graves

Daniel James Graves 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: 12680836
    Abstract: A normal interface surface mating sensor includes a power source, a plurality of electrically conductive sensing elements, and at least one of an ammeter or a voltmeter. The voltmeter is connected in parallel with the first terminal and the second terminal of the power source. The plurality of electrically conductive sensing elements is coupled to the first terminal of the power source, is arranged on a first contact face in a pattern such that a spatial location of each sensing element generates an electrical signal when a conductive area on an opposing contact face physically contacts the first contact face at the spatial location of the sensing element contacted. Measurements from the ammeter and the voltmeter together are output as a contact event indicator that includes a conductivity measurement corresponding to the electrical signal generated by the physical contact at a sequence of the NISMSs contacted.
