  • Driving mechanism for a camera lens
    Patent number: 7145738
    Abstract: A camera lens drive mechanism includes a lens cylinder, and the lens hollow is able to fit over a lens. A conductor coil is wound around an outer surface of the lens cylinder, and a coil spring is surrounding the lens hollow cylinder. A magnetic body is opposite to the conductor coil for the magnetic line of force from the magnet can cut across the conductor coil. An active force is induced on the coil when a current is conducted in the conductor coil, and then the lens cylinder is pushed also. The magnitude of the active force can be controlled by adjusting the magnitude of the current in the conductor coil.

  • Engaging mechanism for heat-dissipating member
    Patent number: 6644386
    Abstract: A heat-dissipating member includes a sheet, an upper extension, and a lower extension. Each extension includes an engaging portion having a pair of opposed engaging hooks with an engaging slot defined therebetween. Each engaging hook is connected to an associated extension via a slant lug. Each engaging portion includes a rear portion extending into an associated extension, thereby leaving a notched portion on an associated end of the sheet. The slant lugs of the engaging portion of the heat-dissipating member are extendible into a rear portion of an engaging slot of another similarly constructed heat-dissipating member, with two edges of a notched portion of another similarly constructed heat-dissipating member being engaged with the engaging hooks of the heat dissipating member.
