  • Patent number: 8520367
    Abstract: Provided are a method of manufacturing a lithium ion capacitor and a lithium ion capacitor manufactured using the same. The method of manufacturing a lithium ion capacitor includes forming a lithium thin film on one surface of a separator; making the lithium thin film in contact with an anode, and alternately disposing the anode and a cathode with the separator interposed therebetween to form an electrode cell; and enclosing the electrode cell and an electrolyte into a housing, and pre-doping lithium ions to the anode from the lithium thin film.

  • Patent number: 8091477
    Abstract: A detonator assembly includes a capacitor, an initiator, a transformer and an addressable chip. The initiator is electrically connected to the capacitor, the transformer is mechanically and electrically connected to the capacitor and the addressable chip is mechanically and electrically connected to the transformer. The initiator may be bonded or fused to the capacitor, and the transformer may be bonded or fused to the capacitor. The capacitor, initiator, transformer and addressable chip form a unified integrated detonating unit.

  • Patent number: 7961452
    Abstract: The semiconductor photoelectrode of the present invention includes a metallic substrate having irregularities in a surface and a semiconductor layer which is formed on the surface of the metallic substrate and composed of a photocatalytic material. This can increase the light absorption efficiency and, furthermore, prevent recombination of charges.

  • Patent number: 7913623
    Abstract: A MEMS fuze having a moveable slider with a microdetonator at an end for positioning adjacent an initiator. A setback activated lock and a spin activated lock prevent movement of the slider until respective axial and centrifugal acceleration levels have been achieved. Once these acceleration levels are achieved, the slider is moved by a V-beam shaped actuator arrangement to position the microdetonator relative to a secondary lead to start an explosive train in a munitions round.
