Abstract: The subject matter of the disclosure relates to low temperature power throttling at a mobile device to reduce the likelihood of an unexpected power down event in cold weather environments. A mobile device employing a power management solution may be configured to determine that a monitored temperature at the mobile device (at the battery of the mobile device) is below a first threshold level, and whether a hardware component (such as a camera) is active or inactive. Then, based on these determinations, the mobile device can select a throttle setting from a first set of throttle settings when the hardware component is active, and a second set of throttle settings when the hardware component is inactive. Subsequently the mobile device can throttle power consumption for one or more components of the mobile device according to the selected throttle setting.

Abstract translation: 本公开的主题涉及在移动设备处的低温功率节流，以减少在寒冷天气环境中意外停电事件的可能性。 采用电源管理解决方案的移动设备可以被配置为确定移动设备（在移动设备的电池处）处的监控温度低于第一阈值水平，以及硬件组件（诸如照相机）是否是活动的 或不活动。 然后，基于这些确定，当硬件组件处于活动状态时，移动设备可以从第一组节气门设置选择节气门设置，以及当硬件组件不活动时可以选择第二组节气门设置。 随后，移动设备可以根据所选择的节气门设置来节省移动设备的一个或多个组件的功率消耗。

Abstract: A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.

Abstract: The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During, operation, the system monitors indicators of user behavior associated with charging and discharging of the battery in the portable electronic device by a user, wherein the indicators of user behavior can include a state-of-charge of the battery, a charging pattern associated with charging of the battery, usage of applications on the portable electronic device, a user setting on the portable electronic device, a scheduled event or alarm on the portable electronic device, a power consumption pattern on the portable electronic device, a time of day, or the location of the portable electronic device. Next, the system modifies a charging technique for the battery based on the monitored indicators of user behavior to manage at least one of a cycle life of the battery, swelling in the battery, and a runtime of the battery.

Abstract: Capacitors, including multilayer ceramic capacitors, may be subject to faults and failures that create short circuits between their dielectrics. Capacitors having fuses that protect the capacitors or the electrical devices using the capacitors when such faults occur are described herein. Embodiments include the presence of monolithic and non-monolithic structures including the fuse. Embodiments also include capacitors with multiple fuses that may prevent or mitigate capacitor failure. Methods for manufacturing and using the capacitors are also described.

Abstract: A system that displays a video signal on a display for a computer system is presented. During operation, the system receives a signal to switch from displaying a video signal from an internal video source to displaying a video signal from an external video source. In this system, the internal and external video sources are coupled to a bi-directional video port for the computer system, wherein the internal video source generates an output video signal and the external video source generates an input video signal. The system then determines whether the external video source is coupled to the bi-directional video port. If so, the system couples the external video source to the display and determines whether the external video source is a valid video source. If the external video source is a valid video source, the system displays the video signal from the external video source on the display.

Abstract: The present disclosure describes systems and methods associated with selective powering of an electronic display in response to operating conditions, additional data, and/or predicting that the electronic display is not going to be viewed or visible. By selectively enabling the electronic display between power states based on a prediction of when a viewer is expected to view the electronic display, a perceivably always-on electronic display may be provided without the electronic display being always-on, thereby balancing consumer interests with technical requirements of a relatively long battery life and correspondingly low power consumption.
