| 20110199045 | POWER TRANSFER DEVICE AND METHOD - The present invention provides a power transfer device that wirelessly transfers AC power for charging at least one load, and an associated method of wirelessly transferring power. The device and method of the invention use phase-shift control to control the wireless transfer of the AC power. | 08-18-2011 |
| 20110187318 | POWER TRANSFER DEVICE AND METHOD - The present invention provides a power transfer device for charging a wireless communication device having a communication bandwidth, and an associated method of transferring power. The device and method of the invention use a spread-spectrum technique to reduce or minimize interference signals within the communication bandwidth and within the power transfer device. | 08-04-2011 |
| 20110134673 | AC-DC CONVERTER AND AC-DC CONVERSION METHOD - The present invention provides an AC-DC converter and AC-DC conversion method for converting an AC input provided by a power transfer winding. The AC-DC converter includes a rectifying means for rectifying the AC input into a rectified output, and a control means for controlling the rectifying means based on a comparison between a reference signal and a voltage feedback signal, the voltage feedback signal being based on the rectified output. | 06-09-2011 |
| 20110084655 | PORTABLE ELECTRONIC DEVICE WITH ANTENNA AND POWER TRANSFER COIL - The present invention provides a portable electronic device including an antenna having a major planar cross-section, and a power transfer coil having windings parallel to a coil plane, the coil plane extending to the perimeter of the power transfer coil. The antenna and the power transfer coil are arranged such that the major planar cross-section is substantially perpendicular to the coil plane if a line directed perpendicularly from the coil plane intersects the major planar cross-section. An associated method of assembling a portable electronic device is also provided. | 04-14-2011 |
| 20110070830 | ANTENNA NETWORK FOR PASSIVE AND ACTIVE SIGNAL ENHANCEMENT - The present invention provides an antenna network for passively or actively enhancing signal transmission or reception of one or more portable transceiver devices. The antenna network includes one or more antennas, each having a coupling portion and a radiating portion, the coupling portion being distributed across a coupling area and the radiating portion being located away from the coupling area, whereby signal transmission or reception of the one or more portable transceiver devices can occur through the radiating portion when the one or more portable transceiver devices are located within the coupling area. | 03-24-2011 |
| 20100046264 | GENERALIZED AC-DC SYNCHRONOUS RECTIFICATION TECHNIQUES FOR SINGLE- AND MULTI-PHASE SYSTEMS - Various circuit configurations and topologies are provided for single and multi-phase, single-level or multi-level, full and half-bridge rectifiers in which diodes are replaced by combinations of voltage-controlled self-driven active switches, current-controlled self-driven active switches and inductors in order to reduce the effects of conduction loss in the diodes. | 02-25-2010 |
| 20100046259 | SINGLE-PHASE SELF-DRIVEN FULL-BRIDGE SYNCHROUNOUS RECTIFICATION - A full-bridge rectifier is configured to provide synchronous rectification with either a current-source or a voltage-source. The rectifier has an upper branch and a lower branch and two current loops, with each of the branches including voltage- or current-controlled active switches, diodes or combinations thereof that are selected such that each loop includes one active switch or diode from the upper branch and one active switch or diode from the lower branch, and each current loop comprises at least one diode or current-controlled active switch, and at least one voltage- or current-controlled active switch is included in one of the upper or lower branches. | 02-25-2010 |
