  • Test board and method for testing rotation speed of fan
    Patent number: 8803547
    Abstract: A method for testing rotation speed of a fan receives a duty cycle ratio related to the fan sent from a dial switch on a test board connected to the fan. The method transmits a pulse width modulation (PWM) signal based on the duty cycle to the fan to power rotation of the fan, then detects the PWM signal transmitted to the fan and a tachometer (TACH) signal transmitted from the fan. The method gathers the duty cycle ratio related to the fan from the PWM signal and an actual rotation speed of the fan from the TACH signal, and displays the duty cycle ratio and the actual rotation speed together on the test board.

  • Method for determining axial direction of bore of bone fixator
    Patent number: 8768023
    Abstract: A method for determining an axial direction of a bore of a bone fixator includes the following steps: obtaining X-ray images of the bore, calculating perpendicular bisectors, determining spatial planes, and obtaining the axial direction of the bore. After X-ray images of the bore are taken from two X-ray source positions, two overlapping images of the bore are obtained for calculating two perpendicular bisectors therein respectively. Each perpendicular bisector and its corresponding X-ray source position define one spatial plane. The intersection of the two spatial planes defines the axial direction of the bore. Now that the axial direction of the bore can be derived from only two X-ray images of the bore taken during an orthopedic surgery, radiation exposure of the patient and of the medical personnel involved can be significantly reduced.

  • Fan control circuit
    Patent number: 8757985
    Abstract: A fan control circuit of a computer includes a fan interface connected to a connector of a fan, a fan controller and an electronic switch chip. The fan controller outputs a pulse width modulation (PWM) signal to the fan interface to control the operation of the fan, and includes a general purpose input/output (GPIO) interface to output a voltage control signal to the electronic switch chip to switch the electronic switch chip on or off. The voltage control signal is at a low level at the start up moment of the computer, and thus does not turn on the fan via the electronic switch chip. After a preset delay period, the voltage control signal becomes a high-level signal under the control of the fan controller so that the fan interface receives the PWM signal.
