Abstract: Electronic devices and accessory devices designed for communication with electronic devices are disclosed. An accessory device suitable for use with an electronic device can receive the electronic device. Subject to authentication, the electronic device can read information stored on the accessory device through respective wireless communication circuitry of the electronic device and the accessory device. For example, the accessory device can store information related to the material makeup of the accessory device, dimensional information of the accessory device, and other integrated features. This information can be read and received by the electronic device. As a result, the electronic device can adjust a control system (that regulates thermal energy generation) by increasing a set point temperature that allows one or more processors to operate in a manner consistent with additional thermal energy generation.

Abstract: An electronic module includes an operational subunit, having upper, lower and lateral surfaces, and including one or more electronic components, which are adjacent to the lower surface of the operational subunit and generate heat when the module is in operation. A heat sink is disposed in proximity to the lower surface of the operational subunit. A heat spreader, including a continuous sheet of a heat-conducting material, is folded to wrap around the operational subunit so that a lower side of the sheet is interposed between the lower surface of the operational subunit and the heat sink and a lateral side of the sheet extends around at least one of the lateral surfaces of the operational subunit.

Abstract: This application relates to an enclosure for a portable electronic device is described. The enclosure can include metal bands included along the enclosure and a support structure. The support structure can include a thermally conductive core that is capable of conducting thermal energy generated by the operational components and rails that are bound between the metal bands and the thermally conductive core, where the rails are characterized as having a rate of thermal conductivity that is less than a rate of thermal conductivity of the thermally conductive core so that the thermal energy generated by the operational component is directed away from the operational component and away from the metal bands.

Abstract: Systems and methods are disclosed for determining a current machine state of a processing device, predicting a future processing task to be performed by the processing device at a future time, and predicting a list of intervening processing tasks to be performed by a first time (e.g. a current time) and the start of the future processing task. The future processing task has an associated initial state. A feed-forward thermal prediction model determines a predicted future machine state at the time for starting the future processing task. Heat mitigation processes can be applied in advance of the starting of the future processing task, to meet the future initial machine state for starting the future processing task.

Abstract: An electronic device may have electrical components that produce heat during operation. An electronic device may also be heated by sunlight incident on the device. A thermal management model may take into account device structures such as housing materials in modeling the thermal behavior of the device. Temperature sensors in the device may be used to measure internal temperatures. The model may use temperature measurements and other data such as environmental data measured with sensors in predicting temperatures for one or more regions in a device. In response to prediction of a temperature greater than a predetermined threshold, the device may take remedial action to avoid overheating. Remedial action may include adjusting electrical components so that they produce less heat, activating a heat blocking component such as an electronic shutter, and reducing communications activity levels and other software activity levels.

Abstract: Embodiments described herein are directed to determining an ambient temperature of an environment in which a device is operating. In some embodiments, the ambient temperature of the environment is determined by determining an initial temperature of the device and also determining when the temperature of the device reaches a first temperature threshold. When the temperature of the device reaches the first temperature threshold, the device is allowed to cool for a predetermined amount of time. Upon expiration of the amount of time, a change in temperature of the device over the amount of time is detected. The detected change in temperature is then used to determine an ambient temperature of the environment in which the device is operating.
