Stephen A. Scearce 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: 11277918
    Abstract: In one implementation, a multilayered printed circuit board is configured to redirect current distribution. The current may be distributed by steering, blocking, or otherwise manipulating current flows. The multilayered printed circuit board includes at least one power plane layer. The power plane layer does not distribute current evenly. Instead, the power plane layer includes multiple patterns with different resistances. The patterns may include a hatching pattern, a grid pattern, a directional pattern, a slot, a void, or a continuous pattern. The pattern is a predetermined spatial variation such that current flows in a first area differently than current flows in a second area.
    Type: Grant

    Date of Patent: March 15, 2022
    Assignee: CISCO TECHNOLOGY, INC.

  • Patent number: 7054127
    Abstract: A cable device includes an integrated surge protection circuit. In the event that, communication signals conveyed by the cable include (potentially damaging) transient voltages, the surge protection circuit integrated in the cable suppresses the transient voltages at a distance from a corresponding electronic circuit to which the cable is attached. Consequently, potentially damaging voltage transients imparted on the communication signals are clamped before reaching potentially sensitive inputs of the electronic circuit.
