A power transmitting apparatus that transmits power to a power receiving apparatus executes intermittent wireless transmission of power. The power transmitting apparatus operates according to one of a first power transmitting method including detecting a signal load-modulated by the power receiving apparatus using an ID in response to the transmitted power during the intermittent transmission and a second power transmitting method including transmitting the power having modulated the power according to an ID determined in advance so that the power receiving apparatus detects the ID determined in advance.

A method of controlling a wireless power receiver. The method includes receiving, by a power receiver, power from a wireless power transmitter; receiving, from the wireless power transmitter, a time set value that is set for checking cross connection; in response to receiving the time set value, generating a power variation in the wireless power receiver by converting a load status from a first load status to a second load status; and maintaining the second load status for a time corresponding to the received time set value.

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.

Multi-port power adapters. At least one example is a method including: supplying a first bus voltage to a first device by way of a DC-DC converter coupled to a link voltage; supplying a second bus voltage to a second device by way of a second DC-DC converter coupled to the link voltage; converting an AC voltage to the link voltage by way of an AC-DC converter; selecting, by a shunt regulator, a setpoint for the link voltage based on the first bus voltage and the second bus voltage; and regulating the link voltage to the setpoint by the AC-DC converter.

A computer implemented method for managing charge availability of a charge unit (CU) to obtain charge for a battery of an electric vehicle (EV) is provided. The CU includes a computer for processing at least part of the method and for communicating with a server over a network. The method includes receiving, by the server, status information from the computer of the CU. The method includes sending to the computer of the CU instructions to make a reservation for the CU. The reservation is for a user account that has requested a desire to charge the battery of the electric vehicle of the user at the CU or another CU. The method includes sending, by the server, a confirmation for the reservation to the user account. The confirmation is viewable via a device having access to the server via the user account. The method includes sending, by the server, a data regarding a time of availability of the CU to the user account for the reservation. The computer of the CU is configured to display a visual indicator regarding the reservation of the CU.

A system includes a first AC bus configured to supply power from a first AC power source. A second AC bus is configured to supply power from a second AC power source. A first transformer rectifier unit (TRU) connects a first DC bus to the first AC bus through a first TRU contactor (TRUC). A second TRU connects a second DC bus to the second AC bus through a second TRUC. A ram air turbine (RAT) automatic deployment controller is operatively connected to the first TRUC and to the second TRUC to automatically deploy a RAT based on the combined status of the first TRUC and the second TRUC.

A system and method for contextually aware charging of mobile devices. In accordance with an embodiment, the system comprises a base unit having one or more charger coils, for use in inductive charging; and one or more components within the base unit for providing context-aware connectivity and/or other capabilities with a mobile device. When a mobile device having one or more receiver coils or receivers associated with, is placed in proximity to the base unit, the charger coil is used to inductively generate a current in the receiver coil or receiver associated with the mobile device, to charge or power the mobile device, and at the same time the context-aware connectivity and/or other capabilities are initiated. In accordance with various embodiments, the base unit and/or the mobile device can adapt to a location or use model of interest to provide different functionalities, applications and features.

A method including controlling a wireless energy transfer apparatus to synchronize energy transfer with at least one further wireless energy transfer apparatus to wirelessly transfer energy to at least one load in combination with the at least one further wireless energy transfer apparatus.
