摘要： A method of operating a power and data transfer system includes determining, by a wireless transmission system, presence of a wireless receiver system. The method further includes starting wireless power and data transfer via the wireless transmission system, if presence of the wireless receiver system is detected. The method further includes determining if power at a load associated with the wireless receiver system exceeds a threshold for out of band communications. The method further includes, if the power at the load exceeds the threshold for out of band communications, handing over wireless data transfer to an out of band communications system that is in operative communication with the wireless transmission system.

摘要： Assembly of non-galvanically coupled networks, having two electrical networks and having a coupling device via which the electrical networks which are each galvanically connected to the coupling device by means of two connecting points are coupled to one another without being galvanically interconnected. The coupling device consists of two active electrical dipoles which are interconnected via at least one data link, can be operated both as a source and as a sink, and have measurement means for current and voltage. The dipoles are designed to provide current and/or voltage for the respective electrical network which are galvanically connected thereto in accordance with a target value received for this purpose from the respective other active electrical dipole, and to transmit the current and/or voltage values subsequently measured at the connecting points to the respective other active electrical dipole as a target value for the source/sink formed by this dipole.

摘要： An exemplary embodiment includes a method of communication between a wireless power receiver to a wireless power transmitter. The method includes receiving, by an antenna of the wireless power receiver, radio frequency (RF) signals from the wireless power transmitter, wherein the wireless power receiver substantially matches an impedance of the wireless power transmitter. The method further includes, while receiving the RF signals from the wireless power transmitter: (a) determining whether a communication criterion is satisfied, and (b) in accordance with a determination that the communication criterion is satisfied, introducing an impedance mismatch between the wireless power receiver and the wireless power transmitter that causes a portion of the RF signals to be reflected by the antenna as a modulated signal, wherein the wireless power transmitter is configured to receive and interpret the modulated signal without using a separate communication radio.

摘要： A wireless power receiver according to some embodiments includes an integrated circuit which includes: a full-bridge rectifier coupled to receive wireless power from a receiver coil; a wireless receiver controller coupled to control the full-bridge rectifier; a pass device coupled between the full-bridge rectifier and an output; and a configurable controller coupled to the switch, the configurable controller configurable as a LDO controller or a Buck controller. A second controller can be coupled to the configurable controller that interfaces to an external Buck low-side transistor if the configurable controller is the Buck controller and provides GPIO if the configurable controller is the LDO controller. A third controller can be coupled to the full-bridge rectifier, which operates as a full-bridge sync rectifier driver multiplexer to select an external driver for one or more of the rectifier transistors. Other features are also provided.

摘要： An antenna configured for wireless power transmission has a puzzled configuration and has a first antenna molecule and a second antenna molecule. The first and second antenna molecules are formed to define a first and second pluralities of coil atoms. The pluralities of coil atoms include a first coil atom and a second coil atom, wherein the second coil atom is positioned substantially diagonally opposite with respect to the first coil atom. The first antenna molecule and the second molecule are overlain to form a first atom row and a second atom row and to form a first atom column and a second atom column. The first and second antenna molecules are substantially inverted versions of one another.
