  • Patent number: 8410632
    Abstract: The present invention discloses a power adapter has a power converter, a power output cable, a first DC power connector and multiple second DC power connectors. The power converter has a casing, a power converting circuit mounted in the casing, and an AC power inlet and DC power outlet electronically connected to the power converting circuit. The power output cable has a DC output and selective connector having two DC power pinholes and multiple selective pinholes surrounding the two DC power pinholes. The first DC power connector has two DC voltage pins and is selectively connected to the DC output and selective connector. Each of the second DC power connectors has a body, a DC plug formed on the body, two DC voltage pins formed on the body and one jumper pin formed on the body and corresponding to the selective pinholes of the power output cable to change voltage of the DC power output from the power converting circuit.

  • Patent number: 7632152
    Abstract: A DC/AC adapter assembly has a DC/AC adapter and a cable. The cable transmits a power-overloading signal to the DC/AC adapter indicating whether power-overloading is occurring in the cable. The DC/AC adapter includes a controller circuit for controlling and adjusting an output alternating current of the DC/AC adapter based on the power-overloading signal to reduce power-overloading occurring in the cable.

  • Patent number: 6775957
    Abstract: A hydrophobic, compressible, resilient filler for keeping pills from movement in a container during handling is provided in the form of a tube that is cut to a desired length and axially compressed in horizontal orientation. The tube is compressed and inserted through the neck portion of the container and allowed to expand to become entrapped within the container so as to apply pressure to keep the pills from movement or damage. An apparatus and method is disclosed for extending a desired length of filler in flattened tubular form from a large supply, to cut the length of tube from the supply, to reconfigure the cross-sectional shape of the filler tube, to axially compress the rounded tube, and to insert the axially compressed filler into a container that is aligned with the insertion ram.

  • Patent number: 6553959
    Abstract: A stratified exhaust gas re-circulation (EGR) engine uses an exhaust port per cylinder for exhausting exhaust gases and to re-circulate exhaust gas. The EGR valve may be phased from the exhaust stroke to the intake stroke. The EGR valves that control the exhaust gas re-circulation ports may be on a separate camshaft from the other valves. The EGR ports and an intake port for each of the cylinders may be helical or tangential ports that stratified the exhaust gas and the air in the cylinder. The engine may be a direct injection or a port fuel injection engine with one or more exhaust manifolds. The exhaust gas re-circulation ports may be controlled by a single flow valve or each port may have a separate flow valve. The intake ports may be controlled by a single flow valve or each intake port may have a separate flow valve.
