20130015705 | CONTACTLESS POWER SUPPLY SYSTEMAANM Abe; HideakiAACI OsakaAACO JPAAGP Abe; Hideaki Osaka JP - A contactless power supply system includes a device and a power supply apparatus that supplies power contactlessly to the device. The power supply apparatus includes a plurality of primary coils provided in a planar or linear manner, a plurality of power supply modules respectively corresponding to the plurality of primary coils, each of the power supply modules configured to receive an excitation request signal for requesting excitation of the primary coil and excite the primary coil based on the excitation request signal, and a system control section configured to integratedly control the plurality of power supply modules. The device includes a secondary coil and a transmitter circuit that sends the excitation request signal to the power supply apparatus. When the device is mounted on the power supply apparatus, the contactless power supply system excites primary coils corresponding to one or more power supply modules, generates secondary power in the secondary coil of the device by electromagnetic induction, and supplies the secondary power to a load of the device. When the excitation request signal from the device mounted on the power supply apparatus is received at the one or more power supply modules, the system control section sends an enable signal for exciting the primary coils to the one or more power supply modules that received the excitation request signal | 01-17-2013 |
20130099592 | CONTACTLESS POWER SUPPLYING SYSTEM AND METAL FOREIGN OBJECT DETECTION DEVICE OF CONTACTLESS POWER SUPPLYING SYSTEM - A contactless power supplying system, which excites a primary coil of a power supplying device to generate an induced electromotive force at a secondary coil of an appliance arranged on the device and supply the induced electromotive force to a load of the appliance, includes a metal foreign object detection device. The metal foreign object detection device includes an antenna coil, an oscillation circuit, and a detection circuit. The oscillation circuit includes a component having a design value that generates oscillation in a range of oscillation conditions from immediately after the oscillation circuit starts to generate oscillation to just before a stable and continuous oscillation condition. The detection circuit detects a suspension of the oscillation or an attenuation in amplitude of the oscillation based on a change in an electric characteristic of the antenna coil caused by a metal foreign object on the power supplying device. | 04-25-2013 |
20130175877 | POWER SUPPLYING MODULE FOR CONTACTLESS POWER SUPPLYING DEVICE, METHOD FOR USING POWER SUPPLYING MODULE OF CONTACTLESS POWER SUPPLYING DEVICE, AND METHOD FOR MANUFACTURING POWER SUPPLYING MODULE OF CONTACTLESS POWER SUPPLYING DEVICE - Coil units equipped with primary coils having the same specification are provided in a power feeding module. Coil-unit intermeshing recess sections are formed on a printed circuit board to match each of the coil units. Pads for joining together with electrodes formed on the coil units are formed on the bottom faces of each of the coil-unit intermeshing recess sections. A plurality of coil units can be mounted onto the printed circuit board easily, by fitting each of the coil units into each of the coil-unit intermeshing recess sections and joining them together, which will enable manufacturing efficiency to be improved. | 07-11-2013 |
20140339911 | CONTACTLESS POWER SUPPLYING SYSTEM, ELECTRIC APPLIANCE, REPEATER, AND ADAPTOR - A contactless power supplying system includes a contactless power supplying device provided with a high-frequency inverter and a primary coil and an electric appliance provided with a secondary coil and a power receiving circuit that supplies induced electromotive force generated by the secondary coil to a load. The system further includes a structure having a variable shape and adapted to be independently secured, and at least one of a connecting wire for connecting the primary coil to the high-frequency inverter, a connecting wire for connecting the secondary coil to the power receiving circuit, and a connecting wire for connecting the power receiving circuit to the load. The at least one of the connecting wires is arranged along the structure. The secondary coil is spatially positioned with respect to the primary coil depending on the shape of the structure. | 11-20-2014 |
