摘要： A system for testing a fan interface on a motherboard is provided. A fan simulator receives a PWM signal from a fan interface of the motherboard, converts the PWM signal to a TACH signal and outputs the TACH signal to a computer via a fan connector. A difference between the actual rotation speed from the TACH signal and a preset desired rotation speed of the fan simulator is determined and analyzed by comparing the difference with a preset allowable error margin.

摘要： A projector and method adjusts light. The projector obtains coordinates of each pixel of an image of a projection screen captured by a camera. Furthermore, the projector converts the coordinates of the pixels of a predetermined shape in the image into the coordinates of the pixels of a DMD chip. The projector adjusts an angle of micromirrors corresponding to the converted coordinates of the pixels of the DMD chip to direct light away from a lens of the projector.

摘要： A projector includes an infrared camera. Projected infrared rays on a screen are detected and the projector calculate coordinates of a center point of a projection area of the infrared ray projected on the screen. The coordinates of the center point is transformed to coordinates of a pixel point on the screen corresponding to a resolution of a projection lens of the projector. The projector determines the pixel point on the screen according to the converted coordinates. A light source of the projector is controlled to highlight the pixel point on the screen.

摘要： A system for detecting a work status of a computer system is provided. The system includes a super input/output (Super I/O) chipset, a complex programmable logic device (CPLD), a South Bridge chipset and a device driver. The device driver is configured for driving the Super I/O chipset to generate and send a start signal to the CPLD, and is further configured for driving the Super I/O chipset to periodically generate and send a test signal to the CPLD. The CPLD is configured for receiving the start signal and triggering a clock to start timing from an initial time, monitoring whether a predetermined amount of test signals have been received in a predetermined time, and is further configured for sending a reboot signal to the South Bridge chipset when the predetermined amount of test signals have not been received in the predetermined time. The South Bridge chipset is configured for rebooting the computer system when receiving the reboot signal. A related method is also provided.
