Abstract: A compass output in a first portable electronic device is monitored as the first device and a second electronic device come closer to each other. It is determined, by a process running in the first device, whether a magnetic field signature that is based on the monitored compass output is associated with a previously defined type of electronic device with which a network device discovery process is to be conducted. Other embodiments are also described and claimed.

Abstract: An asymmetric multiphase boost that provides flash functionality for display backlights. A backlight power management module for a display backlight may implement and control an asymmetric multiphase boost that includes two boost phases: a primary boost phase for typical display backlighting, and a secondary or flash boost phase that provides flash functionality via the display backlight when needed. The primary boost phase may be sized to provide high low-load efficiency, high inductance, and low switching frequency for normal display backlight operations. The flash boost phase may be sized for high current and peak power, low inductance, and high switching frequency for pulsed current applications. Via the asymmetric multiphase boost, the backlight power management module may, for example, be used to provide a camera flash function for front facing cameras.

Abstract: In some implementations, a mobile device can be configured with virtual motion fences that delineate domains of motion detectable by the mobile device. In some implementations, the mobile device can be configured to invoke an application or function when the mobile device enters or exits a motion domain (by crossing a motion fence). In some implementations, entering or exiting a motion domain can cause components of the mobile device to power on or off (or awaken or sleep) in an incremental manner.

Abstract: Measurement data is collected from a magnetic sensor in a portable device, while the device is being carried by its end user and without requiring the end user to deliberately rotate or position the device while the output data is being collected. For example, the device may be held in the user' s hand while walking or standing, or it may be fixed to the dashboard of an automobile or boat. Measurement data may also be collected from one or more positing, orientation or movement sensors. The collected measurement data from one or both of the magnetic sensor and the position, orientation or movement sensor is processed. In response, either a 2D compass calibration process or a 3D process is signaled to be performed. Other embodiments are also described and claimed.

Abstract: The described embodiments include a power-management unit that receives and stores a representation of a temperature state of a battery pack from a battery-monitoring mechanism in a battery pack. For example, an interface circuit (such as a single-wire-interface or SWI circuit) may receive the information from the battery-monitoring mechanism via a signal line, and the information may be stored in a memory (such as a non-transitory computer-readable memory). This stored information is then used by a temperature-monitoring mechanism or circuit to determine the temperature state of the battery pack, which may be used to control or gate charging of a battery in the battery pack.

Abstract: A power-management unit is described that allows a common signal line to communicate data between an integrated circuit (which may be external to the power-management unit) and a battery-monitoring mechanism in a battery pack, and to convey a signal that represents a temperature state of the battery pack to a temperature-monitoring circuit or mechanism that monitors the temperature state of the battery pack. The power-management unit may include a single-wire interface or a multiplexer that, at a given time, selectively couples the signal line from the battery pack either to the integrated circuit or the temperature-monitoring circuit based on a control signal provided by the integrated circuit (for example, via an I2C bus or interface). In this way, the power-management unit may reduce the number of signal lines needed to communicate with the battery-monitoring mechanism and to convey the signal.
