摘要： Embodiments relate generally to determining a location of a computing device. An example system may include a processor. The processor may be configurable to receive a current state of the computing device. The current state may be a charging or non-charging state. The charging state may be a state in which an energy source of the computing device is connected to and/or being charged by an external energy source. The non-charging state may be one in which the energy source is not connected to and/or not being charged by the external energy source. The processor may be configurable to receive information pertaining to wireless signals of a WLAN. The information may include an identification of a nearest transmitting device. The processor may also be configurable to derive a location status of the computing device based on the current state of the computing device and identification of the nearest transmitting device.

摘要： An un-interruptible power supply (UPS) with indication of battery internal resistance includes a processor, a display, an internal resistance sensor assembly and a battery pack. The internal resistance sensor assembly is connected to the processor and the battery pack. The processor is connected to the display, generates a reference internal resistance according to multiple internal resistances detected by the internal resistance sensor assembly within a stable time after installation, generates a stable internal resistance according to an internal resistance of the battery pack detected by the internal resistance sensor assembly after the stable time, compares the stable internal resistance with the reference internal resistance to generate a status of internal resistance of the battery pack, and instructs the display to display the status for user's timely awareness of the condition of the battery pack and prompt action when the performance of the battery pack deteriorates.
