  • Patent number: 8082380
    Abstract: A transceiver that reduces power consumption when data is transferred between devices in different modes. The transceiver is arranged in a first node and in a second node, which communicate between each other. A first control unit generates a first signal transmitted from the first node in predetermined time intervals during a first period that establishes an environment for communication between the first node and the second node. The second node transmits a second signal transmitted in response to the first signal. The first control unit generates a third signal upon detection of the second signal. A second control unit gradually decreases amplitude of the first signal based on the third signal to set the amplitude of the first signal to a predetermined amplitude so that the second node is receivable of the first signal.

  • Patent number: 7921566
    Abstract: A hair trimmer includes a main body, a cutter block and a comb attachment. The cutter block has a stationary blade and a movable blade, both of which are comb-shaped and are slidably in contact with each other. In addition, the cutter block is protrudingly installed at one end of the main body. The comb attachment has a plurality of comb tooth-shaped sections and covers the cutter block. The comb tooth-shaped sections are provided with cut-off hair deflectors to prevent hairs cut by the cutter block from outwardly scattering away from the comb attachment. Furthermore, cut-off hair deflectors located between two neighboring comb tooth-shaped sections are disposed at relatively inner and outer positions.

  • Publication number: 20110067241
    Abstract: A nose hair trimmer that can be washed with a washing liquid without removing a blade unit from the trimmer. The nose hair trimmer, which improves washability, includes a main body case including an interior cavity, which accommodates a rotational inner blade body and collects nose hair clippings, and a disposal port, which communicates the cavity with the exterior. The rotational inner blade body includes an inner blade base, which supports inner blades and has two holding pieces functioning as vanes. Rotation of the rotational inner blade body rotates the holding pieces and produces a flow of washing liquid directed from slits in an outer blade via the interior cavity and toward the disposal port. The washing liquid washes the interior cavity and discharges nose hair clipping from the nose hair trimmer.
