| 20110273909 | FULL-BRIDGE PHASE-SHIFT CONVERTER WITH AUXILIARY ZERO-VOLTAGE-SWITCHING CIRCUIT - A full-bridge phase-shift converter with an auxiliary zero-voltage-switching circuit includes a full-bridge switching circuit, an isolated transformer, an auxiliary zero-voltage-switching (ZVS) circuit, a full-wave rectifying circuit, and a low-pass filtering circuit. The full-bridge phase-shift converter is used to send energy which is supplied from a DC input voltage to a load. Therefore, an auxiliary inductor of the auxiliary ZVS circuit is provided to reinforce sufficient inductive energy on a leading-edge leg, thus achieving normally zero-voltage-switching operations of the full-bridge phase-shift converter. | 11-10-2011 |

| 20090106875 | GOALTENDER'S BLOCKER WITH TRAVERSING GLOVE - A goaltender's blocker has a blocking pad resiliently attached to a goaltender's stick-hand glove, such that the glove is movable from a neutral or unstressed position toward to a displaced position nearer the lower end of the blocking pad. The blocker incorporates biasing means tending to return the glove to the neutral position. This construction allows the glove to traverse downward relative to the blocking pad when the blocking pad is pressed against a playing surface such as an ice hockey rink, thus making it easier for a goaltender to perform the paddle-down manoeuvre or to pick up a dropped hockey stick in a comfortable, economically correct, and technically sound manner. | 04-30-2009 |

| 20110187395 | CORROSION SENSORS - A corrosion sensor includes an insulating substrate, a thin film of a first metallic material formed on the substrate; and an array of areas what includes a second metallic material provided at the surface of the thin film. A method for manufacturing such a sensor is also disclosed. An exemplary embodiment is disclosed in which the thin film is patterned to define a number of tracks, the resistance of which can be monitored in order to determine the degree to which the thin film has corroded. | 08-04-2011 |

| 20110076691 | TWO STEP LATERAL FLOW ASSAY METHODS AND DEVICES - A two step lateral flow assay method for identifying IgE antibodies in a sample comprises applying a sample to a sample port of a device, wherein the device is adapted to deliver the sample to a lateral flow matrix having a plurality of IgE antigen species immobilized at respective positions at a first location; allowing the sample to travel along the lateral flow matrix through the immobilized plurality of IgE antigen species to a second location downstream of the first location; and, after a predetermined period of time, applying liquid buffer to the lateral flow matrix to mobilize labeled reagent which is adapted to bind anti-IgE antibody and which is dried on the lateral flow matrix at a location upstream of the sample port delivery of the sample to the lateral flow matrix, and allowing labeled reagent mobilized by the liquid buffer to travel along the lateral flow matrix through the immobilized plurality of IgE antigen species and bind with any IgE antibody bound to the immobilized IgE antigen species, and to travel to a second location downstream of the first location where the mobilized labeled reagent causes a visible change to occur at the second location. | 03-31-2011 |
