    Abstract: Various embodiments of methods and systems for estimating environmental ambient temperature of a portable computing device (“PCD”) from electrical resistance measurements taken voice coils in a speaker or microphone component are disclosed. In an exemplary embodiment, it may be recognized that the PCD is in an idle state, thus producing little or no thermal energy. Electrical resistance measurements are taken from a voice coil and used to estimate the environmental ambient temperature to which the PCD is exposed. Certain embodiments may simply render the estimated ambient temperature for the benefit of the user or use the estimated ambient temperature as an input to a program or application running on the PCD. It is envisioned that certain embodiments of the systems and methods may use the estimated ambient temperature to adjust temperature thresholds in the PCD against which thermal management policies govern thermally aggressive processing components.

    Abstract: A device that includes a region comprising an integrated device, and a heat dissipating device coupled to the region comprising the integrated device. The heat dissipating device is configured to dissipate heat away from the region. The heat dissipating device includes a fluid, an evaporator configured to evaporate the fluid, a condenser configured to condense the fluid, an inner wall coupled to the evaporator and the condenser, an outer shell encapsulating the fluid, the evaporator, the condenser and the inner wall, an evaporation portion configured to channel an evaporated fluid from the evaporator to the condenser, wherein the evaporation portion is at least partially defined by the inner wall, and a collection portion configured to channel a condensed fluid from the condenser to the evaporator, wherein the collection portion is at least partially defined by the inner wall. The heat dissipating device may be a multi-phase heat dissipating device.

    Abstract: Because the touch temperature of a wearable computing device (“WCD”) may be an insignificant factor for user experience when the WCD is not being worn by a user, embodiments of the solution seek to modify thermal management policies based on an inferred user proximity state. Exemplary embodiments monitor one or more signals from readily available sensors in the WCD that have primary purposes other than measuring user proximity. Depending on embodiment, the sensors may be selected from a group consisting of a heart rate monitor, a pulse monitor, an O2 sensor, a bio-impedance sensor, a gyroscope, an accelerometer, a temperature sensor, a pressure sensor, a capacitive sensor, a resistive sensor and a light sensor. Using the signals generated by such sensors, relative physical proximity of the WCD to a user may be inferred and, based on the user proximity state, thermal policies either relaxed or tightened.
