  • Publication number: 20090273950
    Abstract: A power-saving device for power supply, including a transformer having a primary coil and a secondary coil. The primary coil is electrically connected with a power supply circuit of the power supply. The secondary coil is serially connected with a diode to electrically connect with a load via a load circuit. The power supply circuit controls powering on/off of the primary coil by means of a switch element. The load circuit includes a ?-type filter circuit, which is chargeable and dischargeable. A power indicator circuit is forward parallel connected between the secondary coil of the transformer and the load circuit. The power indicator circuit includes a light-emitting diode. One terminal of the light-emitting diode is connected with P-pole of the diode. The diode acts as a barrier to the discharge of the ?-type filter circuit so as to effectively reduce energy consumption of the power indicator circuit.

  • Publication number: 20090163080
    Abstract: A power plug adapter structure including: a power plug having a mating face and a set of first conductive members disposed on the mating face, two lateral recesses being respectively formed on two lateral faces of the power plug, a locating dent being formed on a wall of at least one lateral recess; and a plug adapter having second conductive members and insertion slots extending to the second conductive member corresponding to the first conductive members. The plug adapter further has two lateral extension sections disposed on two sides of the plug adapter in parallel to the insertion slots corresponding to the lateral recesses. A locating rib is formed on at least one lateral extension section corresponding to the locating dent. When plug adapter is combined with the power plug, the lateral extension sections extend into the lateral recesses with the locating rib inlaid and chucked in the locating dent.

  • Publication number: 20090073659
    Abstract: A structure comprises a high thermally conductive case with a receiver space for a power module, a thermally conductive part being provided on the case to contact a heating component of the power module in the power supply to induct the heat by the heating component to the case and contact the exterior air through the outside surface of case to dissipate the heat; and a housing the inner surface of which directly contact and cover the outside of high thermally conductive case, a grid-formed structure being formed at most of the region of housing to prevent the heat from scalding the person who touches or takes the power supply. With the large heat dissipation area, the heat is transferred through the external air to increase the efficiency of heat dissipation, and further all power parts may operate in a lower temperature to increase the work efficiency of power supply.

  • Patent number: 6773896
    Abstract: The present invention generally provides a method of measuring the biological activity of Coagulation Factor VIIa (Factor VIIa). Specifically, the present invention provides a method for directly measuring the activity of Factor VIIa in a plasma sample. More specifically, the present invention provides a method for utilizing Factor VIIa activity as a bio-marker to monitor Factor VIIa inhibition to screen compounds which are able to inhibit the biological activity of Factor VIIa.
