Abstract: In an embodiment, a system on a chip (SOC) may include one or more central processing units (CPUs), a memory controller, and a circuit configured to remain powered on when the rest of the SOC is powered down. The circuit may be configured to receive audio samples and match those audio samples against a predetermined pattern. The circuit may operate according to a first clock during the time that the rest of the SOC is powered down. In response to detecting the predetermined pattern in the samples, the circuit may cause the memory controller and processors to power up. During the power up process, a second clock having one or more better characteristics than the first clock may become available. The circuit may switch to the second clock while preserving the samples, or losing at most one sample, or no more than a threshold number of samples.

Abstract translation: 在一个实施例中，芯片上的系统（SOC）可以包括一个或多个中央处理单元（CPU），存储器控制器和被配置为当SOC的其余部分断电时保持通电的电路。 该电路可以被配置为接收音频采样并将这些音频样本与预定模式相匹配。 在SOC的其余部分断电的时间内，电路可以根据第一时钟进行操作。 响应于检测样本中的预定模式，电路可以使存储器控制器和处理器加电。 在上电过程中，具有比第一时钟具有一个或多个更好特征的第二时钟可以变得可用。 电路可以切换到第二时钟，同时保持采样，或者丢失至多一个采样，或者不超过阈值数量的采样。

Abstract: A wireless power system may include power transmitting devices, power receiving devices, and power transmitting and receiving devices. During a configuration phase (e.g., when placed adjacent to another device), a battery-powered transmitting device may transmit information to the additional device that identifies a presence of the battery in the transmitting device. The battery-powered transmitting device may periodically report its state of charge to a power receiving device using in-band communication. The battery-powered transmitting device may report its state of charge before a power transfer phase (e.g., in the configuration phase) or during the power transfer phase. The battery-powered transmitting device may report its state of charge to the power receiving device in response to a state of charge query from the power receiving device. The power receiving device may display the state of charge of the battery of the power transmitting device.

Abstract: Wireless power transfer devices may be configured to negotiate with each other to operate. For example, a wireless power standard may provide for various levels of power delivery, various frequencies for power transfer, various operating voltages, and so forth. There may be instances in which it is desirable to provide wireless power transfer devices (both PTx and PRx) that are capable of enhanced performance when paired with a compatible device. For example, devices can be configured to operate at higher or more granular power levels, different frequencies, and so forth.

Abstract: A wireless power system may include power transmitting devices, power receiving devices, and power transmitting and receiving devices. Control circuitry in the power transmitting and receiving device may determine whether to operate in a power receiving mode or a power transmitting mode. The preferred mode for the power transmitting and receiving device may depend on the types of devices within the system, the state of charge of the batteries of the devices in the system, whether or not one or more devices in the system are connected to a wired power source, etc. Each power transmitting and receiving device may have a default mode. Upon detection of an adjacent device, the wireless power transmitting and receiving device enters a configuration phase in its default mode. Before or during a power transfer phase, the power transmitting and receiving device may swap roles from its default mode to another mode.

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 may include devices that transmit and/or receive wireless power. The devices in the wireless power system may exchange packets in order to transfer various types of data. The data may be transmitted using in-band communication. The devices may use locally assigned addresses to communicate with any other device in the wireless power system. During a network discovery process, device lists may be exchanged between the devices until each device has a complete list of all other devices in the network. The list of all other devices in the network may include a respective address for each device that is based on the topology of the network. Even if a first device is not inductively coupled to a second device, the locally assigned addresses may identify an inductive coupling path from the first device to the second device that includes at least one intervening device.

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.
