Demick McMullin 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: 9742091
    Abstract: A method and structure is provided for constructing elastomeric pin arrays using solder interconnects and a non-conductive medium. Pin to pin interconnects are constructed using a solder connection through a non-conductive medium. This structure eliminates the need for PCB structures as the medium, reducing manufacturing cost. In another embodiment one or more elastomeric columns extend through holes or openings in the non conductive medium. The elastomeric columns are fixed securely within the holes preferably with adhesive material. Compression stops are provided on both sides of each elastomeric column for both the upper and bottom surfaces of the non conductive medium.

  • Patent number: 9680245
    Abstract: A method and an electrical interconnect mechanism in which elastomeric pins are printed onto metal retainer tabs having at least one protrusion or tab extending laterally therefrom to engage a catch or recess of the laminated housing so as to locate each of the elastomeric pins and secure them within the housing. In one embodiment a champher may be employed with a catch or recess to engagely secure a second protrusion or tab extending laterally from another side of said elastomeric pin. In another embodiment the elastomeric pin may have a solid metal ring or a slide collar around the center of the pin wherein the ring has one or two tabs for engaging the recess in the housing and if preferred also the recess of a champfer.

  • Publication number: 20150295337
    Abstract: A method and structure is provided for constructing elastomeric pin arrays using solder interconnects and a non-conductive medium. Pin to pin interconnects are constructed using a solder connection through a non-conductive medium. This structure eliminates the need for PCB structures as the medium, reducing manufacturing cost. In another embodiment a non conductive medium has holes therein and serves as a compression stop. One or more first elastomeric column is formed on an upper side of a conductive disc. The conductive disc is fixedly adhered to a pad located on an underside of the non conductive medium aligned so that the one or more first elastomeric column extends through said holes of the non conductive medium. One or more second elastomeric column is formed on an underside or bottom of the conductive medium or disc.
