Abstract
Circuits, methods, and apparatus that can control components of headset computing devices and other devices. An example can determine whether a headset computing device is being worn. If the headset computing device is not being worn, a fan can be stopped. If the headset computing device is being worn, a determination can be made as to whether a temperature of the headset computing device is above a first temperature. If it is, the fan can be turned on. If the temperature of the headset computing device is below the first temperature, the fan can be turned off.
Claims20
A headset computing device comprising:
- a fan controller for controlling a fan of the headset computing device, wherein the fan controller is configured to:
- stop the fan while the headset computing device is detached;
- run the fan while the headset computing device is attached and a temperature of the headset computing device is above a first temperature threshold;
- and
- stop the fan while the headset computing device is attached and the temperature of the headset computing device is below the first temperature threshold.
A headset computing device comprising:
- a system context module to receive inputs from components of the headset computing device to determine whether the headset computing device is attached or detached;
- a power management system daemon to receive the determination of whether the headset computing device is attached or detached;
- a temperature sensor to provide temperature information;
- a fan;
- a system management controller comprising a fan controller to control the fan, wherein:
- when a determination is made that the headset computing device is detached, the power management system daemon instructs the fan controller to turn off the fan;
- when a determination is made that the headset computing device is attached and the temperature information is that the headset computing device is above a first temperature threshold, the fan controller turns on the fan;
- and
- when a determination is made that the headset computing device is attached and the temperature information is that the headset computing device is below the first temperature threshold, the fan controller turns off the fan.
A headset computing device comprising:
- a processor;
- a display;
- a camera;
- an audio circuit;
- a temperature sensor;
- a system management controller comprising a fan controller;
- and
- a fan controlled by the fan controller;
- wherein the fan controller determines that the headset computing device is attached or detached based on inputs from one or more of the display, camera, or audio circuit, and:
- when the headset computing device is detached, the fan controller enters a state where the fan is off;
- when the headset computing device is attached, the fan controller enters a state where the fan can turn on;
- when the headset computing device is attached and temperature sensor detects a temperature above a first temperature threshold, the fan controller runs the fan;
- and
- when the headset computing device is attached and the temperature sensor detects a temperature below a second temperature threshold, the fan controller turns the fan off, wherein the second temperature threshold is equal to or less than the first temperature threshold.
