Processor Temperature Measurement Through Median Sampling

Temperature readings obtained within a computer system from the location of monitored circuit elements may be oversampled at least three times, and a median average of the three parameter readings rather than the arithmetic mean may be used for controlling a device, e.g. a fan, configured to regulate the environmental parameter, e.g. temperature, a the location of the monitored circuit elements. For example, when a CPU temperature reading is requested by the system comprising the CPU, a thermal monitoring system may acquire at least three consecutive temperature readings of the CPU, discard the highest temperature reading and the lowest temperature reading, and return the median reading to be used in controlling a fan configured to regulate temperature at the location of the CPU, resulting in more accurate temperature readings and more accurate fan control. In various implementations, more than three readings may be considered at a time, and running averages based on median values may be computed in a variety of ways to obtain a temperature control value to control the fan.

Thermally activated electrical interrupt switch

A thermally activated electrical interrupt device incorporates a thermally activated portion engaging with an electrical interrupt portion. The thermally activated material expands when heated, causing an interrupt control rod to open an electrical contact. When the interrupt device is placed into an interrupt state, a reset mechanism maintains the interrupt control rod in the interrupt state until specifically reset. An actuating shaft is in operational communication with at least one electrical contact. The actuating shaft is maintained in a thermal monitoring position until an interrupt control rod is moved via a thermally expanding material and engages with the actuating shaft, releasing it from the thermal monitoring position. The actuating shaft is projected via a biasing member to cause a change in state of the electrical contact. The actuating shaft remains in the interrupt state until the user resets the switch.

Control of voltage regulator thermal condition

A system and method for automatically adjusting microprocessor activity following thermal stress of a voltage regulator is disclosed. A thermal monitoring circuit determines whether the voltage regulator has exceeded a predetermined temperature. The thermal monitoring circuit may employ a temperature-sensing component such as a thermistor to determine the temperature or may derive the temperature indirectly, based on the average input (or output) current. When the over-temperature condition occurs, a signal activates the PROCHOT#, or similar, pin on a microprocessor, throttling the microprocessor clock. Where the microprocessor includes no internal power-reducing feature, the signal throttles an external clock coupled to the microprocessor. In either case, execution of the microprocessor is slowed down. At all times, the voltage regulator maintains the ability to supply continuous current to the microprocessor.
