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 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: 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 transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device includes at least one layer of discrete transmitter coils. The wireless transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more discrete transmitter coils in the wireless 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 wireless power system has a wireless power transmitting device that uses an inverter to apply alternating-current signals to a coil. In response, the coil generates wireless power signals that are received by a coil in a wireless power receiving circuit of a wireless power receiving device. While wireless power is being transferred to the receiving device, the receiving device communicates with the wireless power transmitting device using in-band communications. The wireless power receiving device can issue a halt-wireless-power-transmission command using in-band communications to direct the wireless power transmitting device to stop transmitting wireless power. When power is not being transferred, the wireless power transmitting device transmits a series of short impulses that are monitored by the receiving device. The receiving device can direct the transmitting device to resume power transmission by adjusting an adjustable impedance circuit coupled to the wireless power receiving circuit.

Abstract: A wireless power transmitting device transmits wireless power signals modulated at a given power frequency to a wireless power receiving device using a wireless power transmitting coil. The wireless power receiving device may transmit data signals to the wireless power transmitting device. The wireless power transmitting device may include a data receiver that is coupled to the wireless power transmitting coil and that receives the transmitted data. The data receiver may include an input stage, bandpass filter circuitry, demodulator circuitry, and a data stream combiner. The data receiver may further include a power supply noise cancellation circuit. The power supply noise cancellation circuit may include an input stage, a baseband filter, a window filter, a down-sampler, and a difference filter. The power supply noise cancellation circuit may be coupled to the data stream combiner and is configured to mitigate power supply noise interference in the received data.

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 translation: 感应能量传递系统中的接收器装置可以包括触摸感测装置。 如果触摸感测装置的输入表面被触摸，则发射机装置可以周期性地停止传送能量，以允许触摸感测装置感测触摸样本，同时感应能量传递不活动。 附加地或替代地，发射机设备可以通过在第一占空比步骤和在不同的第二第一占空比步骤的一个或多个周期将能量传送到接收机设备来产生平均占空比。 另外或替代地，如果由DC-AC转换器接收的电流等于或超过阈值，则发射机设备可以降低DC-AC转换器接收的电流电平。 附加地或替代地，发射机设备可以仅在从接收机设备接收到响应信号之后对接收机设备进行ping，并传送能量。
