An information handling system includes a memory module having a first thermal sensor for a first memory channel, and a second thermal sensor for a second memory channel. A processor receives a first temperature from the first thermal sensor and a second temperature from the second thermal sensor, and performs a first high bandwidth access of the first memory channel. In response to a predetermined amount of time ending, the processor: receives a third temperature from the first thermal sensor and a fourth temperature from the second thermal sensor; determines a first temperature delta based on a difference between the third and first temperatures; and determines a second temperature delta based on a difference between the fourth and second temperatures. Based on the first and second temperature deltas, the processor determines whether the first or second memory channel is an upstream memory channel.

A method for detecting a wearable device's contact with a living body may be provided, including obtaining a decreasing rate of body temperature and a decreasing a rate of environmental temperature measured by a wearable device worn on a living body; and determining the wearable device's contact with the living body based on a comparison of the decreasing rate of body temperature and the decreasing rate of environmental temperature. A corresponding apparatus and computer program product for detecting a wearable device's contact with a living body may also be provided.

A control method and a control system for temperature trajectory tracking are provided. The method includes: drawing a target temperature trajectory, discretizing the target temperature trajectory, and performing temperature trajectory control based on the discretized target temperature trajectory. The system includes a preset temperature trajectory processor for drawing a target temperature trajectory, a controlled object for characterizing an actual temperature, a platinum resistance sensor for detecting the actual temperature of the controlled object and inputting the actual temperature into a controller, and the controller for drawing an actual temperature trajectory, discretizing the target temperature trajectory, and operating a PID control program to complete temperature trajectory control. The traditional static constant temperature control can be realized, and close tracking of a preset temperature process trajectory in a second-level time level can be realized, thereby meeting requirements of application occasions with strict requirements on temperature change processes in a short time.

The disclosure relates to a life prediction system for a fan of a lamp. The system comprises a fan signal detecting module to detect at least one working parameter of the fan; and a micro control unit to receive the working current signal, the environment temperature signal and the working rotation speed signal of the fan. The detecting module comprises a current detecting unit to detect a working current of the fan and output a working current signal; a temperature detecting unit to detect a working environment temperature of the fan and output an environment temperature signal; and a rotation speed detecting unit to detect and output a working rotation speed signal of the fan.
