摘要： This document discusses, among other things, apparatus, systems, and methods to prevent a voltage of a charging battery from exceeding a voltage threshold, including receiving charging information from a battery and controlling an output current of a travel adapter, including adjusting the received battery current information using a load current to prevent the voltage of the battery from exceeding a voltage threshold, and providing output current limit information to the travel adapter using the adjusted battery current information.

摘要： This document discusses, among other things, apparatus and methods to optimize charging of a battery, including providing a first charge profile configured to provide charge current pulses to a battery in a plurality of steps. In the first charge profile, the charge current pulses can be stepped down in the plurality of steps using a comparison of a terminal voltage of the battery to a clamp voltage. When the terminal voltage meets or exceeds the clamp voltage, a high time current of the charge current pulse can be decreased and the clamp voltage can be increased before providing a subsequent charge current pulse.

摘要： This document discusses among other things, methods and apparatus to conserve energy when providing proximity information. An example apparatus can include an energy emitter configured to emit a first pulse of energy, an energy sensor configured to receive reflected energy from the first pulse of energy, a control circuit including a processor, the processor configured to provide first proximity information of the apparatus with respect to an object using the reflected energy. The control circuit can be configured to control the energy emitter, to compare the first proximity information with second proximity information, and to modulate a delay between the first pulse of energy and a subsequent pulse of energy using the comparison.

摘要翻译： 本文件尤其讨论了优化电池充电的装置和方法，包括提供配置成以多个步骤向电池提供充电电流脉冲的第一充电曲线。 在第一充电曲线中，通过将电池的端子电压与钳位电压进行比较，可以在多个步骤中降低充电电流脉冲。 当端子电压达到或超过钳位电压时，可以减小充电电流脉冲的高时间电流，并且在提供随后的充电电流脉冲之前可以增加钳位电压。
