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: A wireless power system includes a wireless power transmitting device such as a wireless charging mat for charging devices such as a cellular telephone and an earbuds battery case. The earbuds battery case receives earbuds and charges the earbuds from a battery. The wireless charging mat supports bidirectional in-band communications between the cellular telephone and the earbuds battery case. The earbuds battery case provides the cellular telephone with information on the battery charge level associated with the battery in the earbuds battery case and a battery charge level associated with each earbud in the earbuds battery case. The cellular telephone receives battery charge level information through the wireless charging mat and displays corresponding indicators. The earbuds battery case has a visual output device such as a light-emitting diode that is illuminated to indicate that the earbuds battery case is being charged.

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: Multiple wireless power receiving devices operating in accordance with potentially different wireless charging protocols may be placed on a wireless power transmitting device. The wireless power transmitting device sends a frequency-shift-keying packet. If a wireless power receiving device is compliant with a first wireless charging protocol, the device responds to the frequency-shift-keying packet with an amplitude-shift-keying response packet. If the wireless power receiving device is compliant with a second wireless charging protocol, the wireless power receiving device will fail to respond to the frequency-shift-keying packet and the wireless power transmitting device responds by stopping and starting wireless power transmission and awaiting an amplitude-shift-keying packet from the wireless power receiving device in accordance with the second wireless charging protocol.

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.
