Patents by Inventor Mark A. Shadle

Mark A. Shadle 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: 6243192
    Abstract: Printed electrochemical display cells are arranged in layer form with two electrode layers and an electrolyte layer occupying distinct areas of a substrate. When activated, an electrochemical reaction progressively increases the area occupied by the electrolyte layer and progressively decreases the area occupied by the thin-film electrode layer. The thin-film electrode layer recedes at a boundary in common with the electrolyte layer and provides an irreversible indication of change at a rate governed by the electrochemical reaction.
    Type: Grant
    Filed: July 26, 1999
    Date of Patent: June 5, 2001

  • Patent number: 6136468
    Abstract: Printed electrochemical cells including both power cells and display cells are arranged in a partially assembled condition to extend shelf life of the cells. The partially assembled condition is also used as a switching mechanism for controlling activation of some of the cells. The active components of the cells include two electrodes and an electrolyte layer that is maintained out of contact with at least one of the electrodes for interrupting an ionically conductive pathway between the electrodes. The electrolyte is preferably an electrolytic adhesive that is protected by a release layer until the cells are needed for service.

  • Patent number: 5930023
    Abstract: Printed electrochemical display cells are arranged in layer form with two electrode layers and an electrolyte layer occupying distinct areas of a substrate. An electrolyte layer overlaps most of one electrode layer but contacts a smaller portion of the other electrode layer, which is made of a thin film. When activated, an electrochemical reaction progressively increases the area occupied by the electrolyte layer and progressively decreases the area occupied by the thin-film electrode layer. The thin-film electrode layer recedes at a boundary in common with the electrolyte layer and provides an irreversible indication of change at a rate governed by the electrochemical reaction.

  • Patent number: 5912759
    Abstract: An electrochemical display cell has a layered construction including two electrode layers separated by a dielectric layer. Concentric openings are formed in the dielectric layer and one of the electrode layers exposing a designated portion of the other electrode layer. An electrolyte layer overlaps the one electrode layer and the designated portion of the other electrode layer. When activated, current flow cascades through the openings in the one electrode layer and the dielectric layer to the designated portion of the other electrode layer supporting an electrochemical reaction that erodes the designated portion revealing underlying visual information.

  • Patent number: 5747103
    Abstract: A printing station conveys a supply of molten lithium from a heated tank to a nozzle within a protective shroud. A web traverses a chiller also within the shroud. The nozzle dispenses discrete amounts of the molten lithium onto successive portions of the web in contact with the chiller. The chilled lithium solidifies into solid lithium patterns. A sealer also within the shroud prevents exposure of the solid lithium patterns to ambient air. The station can be incorporated into an in-line press for forming a succession of electrochemical cells.
