  • Patent number: 11941339
    Abstract: Described is technology for automatically generating a routing for an integrated circuit (IC) design. Information describing pin-pairs of an integrated circuit (IC) design is received. An initial routing of the IC design is determined by (i) defining connected wires between each pin-pair in the set of pin-pairs, and (ii) evaluating a target resistance for the pin-pair over the connected wires, wherein each connected wire is routed with other connected wires. A resistance adjustment is applied to adjust wire resistance of the connected wires of the initial routing. The resistance adjustment can be based on a square routing in response to a wire resistance being below the target resistance; or the resistance adjustment can be based on a multi-layer stacking in response to the wire resistance being above the target resistance. The routing is provided in patterns as generated by the initial routing and the resistance adjustment.

  • Patent number: 9366840
    Abstract: A method for manufacturing a base structure of lens-focusing mechanism first prepares a conductive member having at least two conductive parts, interconnection part, contacts and two conductive pins. The conductive parts have proximity ends separated and staggered to each other. An insulating base is formed by injection molding and encapsulates the conductive member wherein the conductive pins, the interconnection part and the contacts are exposed out of the insulating base. The interconnection part is cut and then a spring member is mounted to the insulating base and electrically connected to the conductive pins through the contacts. The present invention can solve the problem of difficulty in assembling conductive pins and connecting the spring member for the insulating base. The conductive member is arranged within the insulating base such that plastic material can be saved, the flatness, the stability and the anti-damage ability of base can be enhanced.

  • Publication number: 20080157609
    Abstract: A plate spring for voice coil motor includes a flat plate having a central opening and provided around the central opening with an even number of identically shaped slits. The slits are so bent and staggered on the flat plate that the flat plate is divided into an inner movable portion and an outer fixed portion, which are connected via an even number of three-section linear elastically bendable portions. When the inner movable portion is subjected to an external force, the elastically bendable portions are elastically bent to allow the inner movable portion to move forward or backward relative to the outer fixed portion without sideward inclining; and when the external force is released, the inner movable portion is automatically and quickly returned to an original position by an accumulated restoring force of the elastically bendable portions.
