  • Patent number: 8686292
    Abstract: The method and system of high-resistance, multiple-conductor flat cables which contain integral tunable resistance sections suitable for fine tuning the resistance of a conductor to match the resistance of the conductors to one another within a specified target value. The method involves the design and creation of the high-resistance, multiple-conductor flat cables and the tuning of the resistance of the conductor.
    Type: Grant

  • Patent number: 6931727
    Abstract: This invention is an electrical connection method for connecting multiple conductor cable, ideally flat flexible cable. The method involves using an actuator for pressing the cable against multiple contacts in a base, each of which contacts has a sharp edge for removing insulation from the cable.

  • Publication number: 20020160648
    Abstract: This invention results from the realization that a multiple conductor cable connector can be made more compact than previously available connectors by using a more narrow contact for each conductor in the cable, can be made more convenient by enabling all conductors contained in the cable to be connected with a single user motion, and can connect to cable without damaging the mechanical or electrical integrity of the cable conductors. This invention is an electrical connector for connecting multiple conductor cable, ideally flat flexible cable. The contacts are positioned substantially in parallel with each other and are located at least partially within the base of the electrical connector. Each contact has at least one cutting edge. The cutting edge is preferably a part of the contact with a sharp edge capable of removing insulation from flat flexible cable.
