  • Patent number: 6717819
    Abstract: A solderable flexible adhesive interposer having solderable contacts includes low-modulus-of-elasticity (i.e. molecularly flexible) conductive adhesive vias to which contacts of an electronic device, such as a semiconductor chip or die or other component, are connected. The flexible adhesive interposer substrate includes a sheet or layer of a molecularly flexible dielectric adhesive having via holes therein through which the flexible conductive adhesive vias reside. A thin layer of solderable metal, preferably a plating of gold or nickel-gold, on at least one exposed surface of the flexible conductive adhesive vias provides the solderable contacts connecting electrically to the conductive vias. The electronic device may be covered by a lid or by an encapsulant attached to the flexible adhesive interposer substrate and/or the electronic device.

  • Publication number: 20040046021
    Abstract: The voting apparatus, system and method of the invention provides at least two independently means for recording and counting votes, e.g., one associated with the voting apparatus and one separate therefrom. A preferred voting apparatus, system and method may provide triple data redundancy in that each vote is recorded by three independent and verifiable means: i.e. by recording in one or more electronic memory devices included in the voting machine and/or system, by recording in the memory of a smart card separate from the voting machine and/or system, and/or by a confirmatory printed record for each voter. The invention may utilize a voting session identifier to provide transparency of the vote and to maintain the anonymity of the votes and voters.
