Patents by Inventor Edwin James Harris, IV

Edwin James Harris, IV 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: 7258819
    Abstract: The present invention provides an improved voltage variable material (“VVM”). More specifically, the present invention provides an improved printed circuit board substrate, an improved device having circuit protection an improved data communications cable having circuit protection and a method for mass producing devices employing the VVM substrate of the present invention. The VVM substrate eliminates the need for an intermediate daughter or carrier board by impregnating conductive particles and possibly semiconductive and/or insulative particles associated with known volatage variable materials into the varnish or epoxy resin associated with known printed circuit board substrates.

  • Patent number: 6547597
    Abstract: An apparatus and method for incorporating surface mount components into connectors. In an embodiment, an apparatus that houses a printed circuit board having a surface mount component is provided. The apparatus includes a body. A plurality of leads are fixed to the body so that an external electrical device is enabled to electrically communicate with the leads. A clip extends from each lead and receives an end of a printed circuit board.

  • Patent number: 6351011
    Abstract: A number of integrated circuit dies having on board protection against electrical overstress (EOS) transients are provided. Generally, the devices have an integrated circuit die with an outer periphery and a functional die area. A plurality of conductive input/output pads are formed on the integrated circuit die. Typically, a first conductive guard rail is disposed on the integrated circuit die and forms a gap between each one of the input/output pads. A voltage variable material is disposed in the gaps between the conductive guard rail and the input/output pads. Typically, a plurality of electrical leads are electrically connected to a respective one of the plurality of conductive input/output pads. At normal operating voltages, the voltage variable material is non-conductive. However, in response to an EOS transient, the voltage variable material switches to a low resistance state, providing a conductive path between the conductive guard rail and the input/output pads.

  • Patent number: 5977860
    Abstract: A surface-mount fuse for protecting a circuit, which includes a substrate having first and second surfaces, each surface having first, second, third, and fourth ends, the substrate also having first, second, third, and fourth sides. The fuse includes a metal strip attached to the first surface of the substrate with a layer of adhesive material, the layer of adhesive material being disposed between the metal strip and the first surface of the substrate, the metal strip having a first connection region, a second connection region, and a non-linear fuse link therebetween. The fuse further includes first and second wire leads, the first wire lead being conductively connected to the first connection region and horizontally projecting away from the first connection region, the second wire lead being conductively connected to the second connection region and horizontally projecting away from the second connection region, for connecting the fuse to the remainder of the circuit.

  • Patent number: 5699032
    Abstract: A surface-mount fuse for protecting a circuit, includes a substrate having first and second surfaces, each surface having first, second, third, and forth ends, the substrate also having first, second, third, and fourth sides. The fuse also includes a metal strip evenly attached to the first surface of the substrate with a layer of adhesive material, the layer of adhesive material being disposed between the metal strip and the first surface of the substrate, the metal strip having a first connection region, a second connection region, and a non-linear fuse link therebetween.
