John T. Grzan 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: 8026454
    Abstract: A linear pressure switch is described that has two conductors separated by strips of insulation. The conductors are resilient members that can vary in thickness and material along with the insulation to provide a range of switch sensitivities. The switch can include connectors and an attachment mechanism that facilitates the installation and removal the switch from a given application. In addition, the switch can ergonomically enhanced actuation. The switches can be stacked in layers and selectively have different sensitivities to provide a desired signal output for each switch in a given application. The switch can also include external coatings on the jacket which enhance the feel and resistance of the jacket to wear and misuse.
    Type: Grant
