A controller defines a power-transmission-mode of operation and a foreign-object-detection-mode of operation. In the power-transmission-mode of operation: a power-stage provides a potential-difference across a first-end and a second-end of the LC circuit. In the foreign-object-detection-mode of operation: for a recuperation-time-interval, the power-stage provides a potential-difference across the first-end and the second-end of the LC circuit that has the opposite polarity to the current through the power-transmitting-coil; after expiry of the recuperation-time-interval, the first-end of the LC circuit is connected to the second-end of the LC circuit such that the LC circuit is short-circuited and defines a closed-LC-circuit; and the controller receives measured-signalling that is representative of an operating parameter of the power-transmitter-unit. The controller further processes the measured-signalling in order to provide an indication of whether or not a foreign object has been detected. | 2019-10-10 |
20190312468 | FOREIGN SUBSTANCE DETECTION METHOD FOR WIRELESS CHARGING AND APPARATUS THEREFOR - The present invention relates to a foreign substance detection method, and an apparatus and a system therefor. A foreign substance detection method in a wireless power transmitter, according to an embodiment of the present invention, may comprise the steps of: if an object placed in a charging area is detected, searching for a current peak frequency with a maximum quality factor value in an available frequency band; receiving, from a wireless power receiver, a foreign substance detection state packet including a reference peak frequency; determining a foreign substance detection reference frequency on the basis of the reference peak frequency; and determining whether or not a foreign substance is present by comparing the current peak frequency with the foreign substance detection reference frequency. Therefore, the present invention has an advantage of being capable of detecting a foreign substance more effectively and accurately. | 2019-10-10 |
20190312469 | POWER RECEIVING APPARATUS, POWER TRANSMISSION APPARATUS, CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM - A power receiving apparatus, which has a first communication function and a second communication function, controls the first communication function to receive a first signal including information representing whether a power transmission apparatus can execute control communication using a second method, controls, based on the information representing that the power transmission apparatus can execute the control communication using the second method, the first communication function to transmit, to the power transmission apparatus, a second signal to request identification information of the power transmission apparatus for the communication of the second method and receive the identification information from the power transmission apparatus, and determines which one of the first communication function and a second communication function should be used for the control communication, based on the first signal and whether the identification information is received. | 2019-10-10 |
20190312470 | METHOD AND APPARATUS FOR RECEIVING AND TRANSMITTING DATA INFORMATION - Methods and terminals for receiving and transmitting data information are provided. The method for receiving data information includes: determining whether information of a wireless power receiving module of a mobile terminal, obtained within a power transmission range by a wireless power transmitting module, satisfies a preset condition; and in response to the information of the wireless power receiving module satisfying the preset condition, performing a preset function of the mobile terminal. The preset function includes receiving and outputting a prompt message that is originally supposed to be outputted on the mobile terminal. | 2019-10-10 |
20190312471 | ELECTRIC MACHINE - An electrical machine includes a casing including a base wall provided with a projection projecting from the base wall towards the inside of the casing. A stator includes a core having a plurality of pole shoes, a plurality of conductors wound on the pole shoes to form a plurality of coils constituting a stator winding. Insulators are interposed between the core and the stator winding. A coil of the winding has an end portion engaged with the projection for heat exchange. The insulators include a housing for a first number of turns of the coil and a second housing for a second number of turns of the coil. The first and second housings are shaped such that a layer of the turns of the end portion abutted against the projection is defined by stretches of the conductors all substantially coplanar with each other. | 2019-10-10 |
