  • Publication number: 20220164011
    Abstract: The disclosed computer-implemented method may include (1) obtaining, within a local environment in which a user is in physical contact with an electronic device, a current value for each of a plurality of measurable characteristics associated with at least one of the user or the local environment, (2) determining, based on the current value for each of the plurality of measurable characteristics, a temperature threshold for the electronic device, (3) measuring a current temperature of the electronic device, (4) comparing the current temperature to the temperature threshold, and (5) initiating, in response to the current temperature exceeding the temperature threshold, a heat mitigation operation of the electronic device to lower the current temperature. Various other methods, electronic devices, and computer-readable media are also disclosed.

  • Patent number: 11042174
    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.

  • Patent number: 10649503
    Abstract: A device that includes a die, a thermal interface material (TIM) coupled to the die, and an electromagnetic (EMI) shield coupled to the thermal interface material (TIM). The electromagnetic (EMI) shield is configured to compress the thermal interface material (TIM). The electromagnetic (EMI) shield comprises a flexible portion. In some implementations, the thermal interface material (TIM) is compressed by the electromagnetic (EMI) shield such that the thickness of the thermal interface material (TIM) is reduced by about at least 10˜20 percent.

  • Publication number: 20180143862
    Abstract: A method includes generating temperature information from a plurality of temperature sensors within a computing device, wherein a first one of the temperature sensors is physically located at a first processing unit of the computing device; processing the temperature information to identify that the first temperature sensor is associated with temperature that is at or above a threshold; and assigning a processing thread to a first core of a plurality of cores of a second processing unit in response to identifying that the first temperature sensor is associated with temperature that is at or above the threshold and based at least in part on a physical distance between the first core and the first temperature sensor.

  • Patent number: 9943008
    Abstract: An electronic device includes an integrated circuit, a flexible heat spreader, an actuator, and a controller. The actuator is coupled to the flexible heat spreader and the controller is configured to control the actuator between a first actuation mode and a second actuation mode. When in the first actuation mode, the actuator positions the flexible heat spreader with an air gap between the flexible heat spreader and the integrated circuit such that the flexible heat spreader is thermally separated from the integrated circuit to increase a thermal impedance between the flexible heat spreader and the integrated circuit. When in the second actuation mode, the actuator positions the flexible heat spreader in thermal contact with the integrated circuit without the air gap there between to reduce the thermal impedance between the flexible heat spreader and the integrated circuit.
