Abstract: A receiver device in an inductive energy transfer system can include a touch sensing device. If the input surface of the touch sensing device is touched, a transmitter device can periodically stop transferring energy to allow the touch sensing device to sense touch samples while inductive energy transfer is inactive. Additionally or alternatively, a transmitter device can produce an averaged duty cycle by transferring energy to the receiver device for one or more periods at a first duty cycle step and for one or more periods at different second first duty cycle step. Additionally or alternatively, a transmitter device can reduce a current level received by a DC-to-AC converter if the current received by the DC-to-AC converter equals or exceeds a threshold. Additionally or alternatively, a transmitter device can ping a receiver device and transfer energy only after a response signal is received from the receiver device.

Abstract: The embodiments set forth a technique for coordinating notifications across computing devices placed onto a wireless charging apparatus. According to some embodiments, the technique can involve the wireless charging apparatus (1) receiving, from a first computing device, first information that includes (i) a first unique identifier (ID) associated with the first computing device, and (ii) one or more unique IDs that are each associated with a respective auxiliary computing device known to the first computing device. Subsequently, the wireless charging apparatus can receive, from a second computing device, second information that at least includes a second unique ID associated with the second computing device. Finally, the wireless charging apparatus can, in response to determining that the second unique ID is included in the one or more unique IDs, and cause both the first and second computing devices to display respective notifications in a coordinated manner.

Abstract: Embodiments describe electromagnetic shielding for wireless charging systems. A wireless charging system includes a transmitter coil configured to generate a magnetic flux, a receiver coil positioned coaxial with the transmitter coil to receive the generated magnetic flux, where electrical interaction between the transmitter coil and the receiver coil generates electric fields, a transmitter shield positioned between the transmitter coil and the receiver coil to intercept some of the electric fields directed away from the transmitter coil and allow the magnetic flux to pass through the transmitter shield, and a receiver shield positioned between the transmitter shield and the receiver coil to intercept some of the electric fields directed away from the receiver coil and allow the magnetic flux to pass through the receiver shield.

Abstract: A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more conductive traces in the transmitter device based on the position of the receiver device on the charging surface. The size and shape of each section of the charging surface that is used to transfer energy to a receiver device can change dynamically based on each receiver device. Additionally, the process of transferring energy to each receiver device may be adjusted during energy transfer based on conditions specific to each receiver device.

Abstract: A method for operating an inductive energy transfer system that includes a transmitter device and a receiver device can include the transmitter device transmitting (500) a ping during a first time period, and within a given time period after the first time period, the transmitter device detects (504) the receiver device is transmitting a signal. The transmitter device may then extend (508) the given time period, and the transmitter device can determine (510) if it receives a complete signal from the receiver device. If the transmitter device receives a complete signal, the transmitter device can transfer (512) energy to the receiver device based on the receipt of the complete signal.
