An electronic device may receive wireless power from a wireless charger device by bypassing an external device in which a coil is isolated. The electronic device may directly supply power received from the external device to an element for executing an operation, without passing through a battery, according to a battery state, or wirelessly share its own power with the external device.

An inductive power transfer system is arranged to transfer power from a power transmitter to a power receiver via a wireless power signal. The system supports communication from the power transmitter to the power receiver based on load modulation of the power signal. The power receiver transmitting a first message to the power transmitter which comprises a standby power signal requirement for the power signal during a standby phase. The power transmitter receives the message, and when the system enters the standby phase, the power transmitter provides the power signal in accordance with the standby power signal requirement during. A power receiver configurable standby phase is provided which may for example allow devices to maintain battery charge or to provide fast initialization of the power transfer phase.

A personal digital ID device provides a digital identifier to a service for a predetermined duration in response to user interaction. The user interaction may include a button press. The personal digital ID device may be in the form of a bracelet, a key fob, or other form factor. The service may be provided by a mobile device, in the cloud, or elsewhere.

Systems and methods for vendor-agnostic access to non-volatile memory of a wireless memory tag are provided. A wireless memory host includes a radio and controller. The controller generates vendor-agnostic commands to access a register-based interface that ultimately results in access to the non-volatile memory.

A method for operating a wireless control device includes the starting up of a control circuit following the actuation, by a user, of a control unit coupled to an energy harvesting device to recharge an energy reserve which electrically powers the control device; the sending of a control message including a control command; the comparison of the elapsed time since the starting up of the control circuit with a first threshold value; when the elapsed time is greater than or equal to the first threshold value, the sending of a pairing request message to the electronic unit.

A magnetic alignment system can include a primary annular magnetic alignment component and a secondary annular magnetic alignment component. The primary alignment component can include an inner annular region having a first magnetic orientation, an outer annular region having a second magnetic orientation opposite to the first magnetic orientation, and a non-magnetized central annular region disposed between the primary inner annular region and the primary outer annular region. The secondary alignment component can have a magnetic orientation with a radial component.

A wireless power transmission method executed by a power transmitter comprising multi-coils, according to one embodiment of the present invention, comprises the steps of: detecting a second power receiver while transmitting power to a first power receiver; determining at least one primary coil adequate for power transmission; by using the determined at least one primary coil, determining whether the second power receiver supports a shared mode protocol; and if the second power receiver supports the shared mode protocol, transmitting power to the first and second power receivers according to the shared mode protocol, wherein the shared mode protocol may be a protocol for simultaneously managing information exchanges between the power transmitter and multiple power receivers.

Apparatuses including multiple selectable circuit elements are described. In an example, an apparatus may include a power supply configured to output a voltage. The apparatus may further include a controller connected to the power supply and a transmission unit connected to the controller. The transmission unit may be configured to output power. The transmission unit may include comprising an inverter connected to the power supply. The inverter may include a high-side switching element. The transmission unit may further include a circuit element a circuit connected to the power supply. The circuit may be configured to select the circuit element. The circuit may include a switch connected between the inverter and the circuit element. The switch and the high-side switching element may be configured to be driven by the voltage outputted by power supply. The controller may be configured to control the power being outputted by the transmission unit.

A method for programming a network transceiver is provided. The method includes: providing a network transceiver having a programming interface; obtaining transceiver identification information via a radio-frequency transceiver programming system (RTPS); obtaining, via the RTPS, configuration data for the network transceiver based on the transceiver identification information; transmitting, via the RTPS, at least some of the configuration data via a radio-frequency (RF) interface; and programming the network transceiver via the programming interface using the at least some of the configuration data received via the RF interface. Corresponding systems, apparatuses (including smart labels, host devices, and transceivers) are also provided.
