Temperature threshold adjustment based on human detection
View Patent ↗A system comprises a first proximity sensor adapted to detect a human. The system further comprises logic coupled to the first proximity sensor. The logic adjusts a temperature threshold based on whether a human has been detected.
1. A method, comprising:
determining whether a human is in contact with a computer based on a signal from a proximity sensor in the computer; and
in response to determining the human in contact with the computer:
decreasing a temperature threshold for the computer from a first temperature threshold to a second temperature threshold;
based on a signal from the proximity sensor indicating continued contact of the computer by the human for more than a predetermined period of time, further decreasing the temperature threshold from the second temperature threshold to a third temperature threshold; and
detecting whether the temperature threshold has been exceeded and, in response to detecting that the temperature threshold has been exceeded, throttling a processor.
2. The method of claim 1 further comprising in response to determining that the human is not in contact with the computer, increasing the temperature threshold.
3. The method of claim 1 further comprising in response to detecting that the temperature threshold has been exceeded, causing at least one of turning on a fan, and increasing fan speed.
4. A computer, comprising:
a fan;
a processor;
a proximity sensor to detect when a human is in contact with the computer; and
logic coupled to said proximity sensor, said fan, and said processor, said logic to adjust a temperature threshold based on whether a human has been detected, and said logic to control the fan and to throttle the processor;
wherein, based on a signal from the proximity sensor indicating presence of a human, the logic is to decrease the temperature threshold from a first temperature threshold to a second temperature threshold, and based on a signal from the proximity sensor indicating continued presence of the human for more than a predetermined period of time, the logic is to further decrease the temperature threshold from the second temperature threshold to a third temperature threshold.
5. The system of claim 4 wherein, based on a signal from the proximity sensor indicating that the human is not in contact with the computer, the logic is to increase the temperature threshold from the third temperature threshold to the second temperature threshold, and based on a signal from the proximity sensor indicating that the human still is not in contact with the computer, the logic is to further increase the temperature threshold from the second temperature threshold to the first temperature threshold.
6. The system of claim 4 wherein the proximity sensor comprises at least one of a capacitive sensor and an optical sensor.
7. The computer of claim 4 wherein the computer is a laptop computer.
