Abstract: Method and systems for dynamic current redistribution in electronic devices with external power storage devices are disclosed. The dynamic current redistribution system includes a set of policies for each state of the electronic device. Depending on a device state, the system identifies the policies to be put in place, and directs current according to the policies. The electronic device may be connected to an external power source in one state, an external battery device in another state, and may be connected to both in a third state.

Abstract: A small capacity battery for powering electronic devices, such as an e-book reader, is provided. This small capacity battery is designed to produce low area-specific resistance, which maintains usable operating voltages even during periods of high current draw. As a result, a lighter and smaller form-factor battery may provide the same battery capacity as a larger and heavier conventional battery. A user may then be provided with a lightweight and small form-factor electronic device that achieves an extended battery life.
Abstract translation: 提供了用于为诸如电子书阅读器的电子设备供电的小容量电池。 该小容量电池设计用于产生低面积电阻，即使在高电流耗散期间也能维持可用的工作电压。 结果，更轻和更小的形状因子电池可以提供与较大和较重的常规电池相同的电池容量。 然后，可以向用户提供实现延长的电池寿命的轻量级和小尺寸的电子设备。

Abstract: Method and systems for configuration and control of an inter-integrated circuit (I2C) bus interface are described. An electronic device that may be connected to an external battery device via a modified connector is also described. The connector has multiple interconnect pins, and one of the interconnect pins of the connector is multiplexed to receive data operation and interrupt or signaling operation on a single line. The single line is configured to not only detect a connection with the external battery device, but also to perform data operations including read/write operations between the electronic device and the external battery device.
