  • Patent number: 4431882
    Abstract: A more transparent capacitance membrane switch in which capacitance elements are offset from their associated switch locations so as to be out of the transparent field of view through the switch.
    Type: Grant
    Filed: August 12, 1982
    Date of Patent: February 14, 1984
    Assignee: W. H. Brady Co.
    Inventor: Norman J. Frame
  • Patent number: 4415781
    Abstract: A membrane switch in which switch activation produces a change in the combined resistance and capacitance across leads of the switch.
    Type: Grant
    Filed: November 20, 1981
    Date of Patent: November 15, 1983
    Assignee: W. H. Brady Co.
    Inventors: Norman J. Frame, James P. Walber, Jan M. Janick
  • Patent number: 4412209
    Abstract: A switch assembly with a different combination of resistance and capacitance associated with each of a plurality of switches and with as few as two leads connecting the plurality of switches to external circuitry. The external circuitry detects switch activation by sensing combined resistance and capacitance across the switch leads.
    Type: Grant

    Assignee: W. H. Brady Co.
    Inventors: Norman J. Frame, James P. Walber, Jan M. Janick
  • Patent number: 4405849
    Abstract: A flexible multilayered membrane switch having electrically conducting contacts comprising Ti.sub.2-x N or Ta.sub.2-x N, to reduce oxidation of the surfaces of the contacts.
    Type: Grant
    Filed: March 8, 1982
    Date of Patent: September 20, 1983
    Assignee: W. H. Brady Co.
    Inventor: Norman J. Frame
  • Patent number: 4400758
    Abstract: A capacitance-type membrane switch in which ordinarily spaced-apart contacts are positioned other than directly over an associated capacitance spacing element with an inner insulating layer and outer conductive portions.
    Type: Grant
    Filed: June 29, 1981
    Date of Patent: August 23, 1983
    Assignee: W. H. Brady Co.
    Inventor: Norman J. Frame
  • Patent number: 4376145
    Abstract: An electroluminescent display device is provided in which electroluminescent portions are defined by first laying down a layer of electroluminescent host material and thereafter doping this layer in selected portions with an electroluminescent activator.
    Type: Grant
    Filed: January 18, 1982
    Date of Patent: March 8, 1983
    Assignee: W. H. Brady Co.
    Inventor: Norman J. Frame
  • Patent number: 4373124
    Abstract: A capacitance-type switch in which an integral capacitance spacer layer element extends over and is severally movable toward and away from separate contact elements of separate switches.
    Type: Grant
    Filed: May 11, 1982
    Date of Patent: February 8, 1983
    Assignee: W. H. Brady Co.
    Inventor: Norman J. Frame
  • Patent number: 4373122
    Abstract: A capacitance switch in which a capacitance spacing element is bent around an end of a spacer centrally relieved for strain relief.
    Type: Grant
    Filed: October 16, 1981
    Date of Patent: February 8, 1983
    Assignee: W. H. Brady Co.
    Inventor: Norman J. Frame
  • Patent number: 4369393
    Abstract: An electroluminescent display which includes a thin film layer of a material which, if undue current passes through a portion of it, that portion is converted from a semiconductor into an insulator.
    Type: Grant
    Filed: November 28, 1980
    Date of Patent: January 18, 1983
    Assignee: W. H. Brady Co.
