Abstract:
A heat dissipating assembly for dissipating heat from a graphic card and a hard disk driver (30), includes a heat sink (10) for contacting the graphic card and a fan duct (20) fixed on the heat sink. The fan duct is made by bending a planar metal plate and has a first portion soldered to a top face of the heat sink and a second portion slantwise and upwardly extending from the first portion. When a fan (40) generates an airflow towards the heat sink, a part of the airflow flows through the heat sink to remove heat in the heat sink, and another part of the airflow is guided slantwise and upwardly by the second portion of the fan duct to flow through the hard disk driver, thereby to cool the hard driver.

Abstract:
A resistance-measuring circuit includes a controller for outputting a PWM signal and further for adjusting the duty cycle of the PWM signal, and a sampling circuit for processing the PWM signal and transmitting the processed PWM signal to the sensor. The sampling circuit samples the signal outputted from the sensor to generate a sampled signal with the voltage thereof changing according to any change in the duty cycle of the PWM signal, and further transmits the sampled signal to the controller. The controller obtains the real-time duty cycle of the PWM signal when the voltage of the sampled signal reaches a threshold voltage, and further calculates the exact resistance of the sensor according to the obtained real-time duty cycle of the PWM signal and the threshold voltage. An electronic device with the resistance-measuring circuit is also provided.
