  • Publication number: 20140211455
    Abstract: An image display device with organic light-emitting diodes (OLEDs) includes a first cover and an organic light-emitting diode (OLED) module. The first cover has a first light transparent zone and a first mask zone. The first light transparent zone forms a first image. The first mask zone is complementary with the first light transparent zone. The OLED module is positioned against the first cover and includes a plurality of juxtaposed organic light emitting diode (OLED) pixels emitting light to project to the first cover. The light includes transmission light and reflective light. The transmission light passes through the first light transparent zone to display the first image. The reflective light is blocked by the first mask zone. Thus the first image can be displayed with a continuous and smooth border on the curvature contour to improve resolution and visual appeal.

  • Publication number: 20050030858
    Abstract: The invention uses a thermistor to detect the ambient temperature of a pickup head. When the temperature is higher than a first predetermined temperature, the speed of the spindle motor of the optical disk drive is decreased for eliminating the heat produced from the power driver and actuator. In this way, the pickup head can be protected from burning out or suffering heat-related damage.

  • Publication number: 20040100891
    Abstract: A method of startup for an optical drive with an auto-balance system. When an optical disk is provided in the optical drive with the auto-balance system, a startup procedure, which includes a servo activating procedure and a system parameter adjustment procedure, is performed. Further, a rotation speed control procedure is performed cyclically according to a spindle motor RPM profile when the system parameter adjustment procedure is performed, so that data stored in the optical disk is correctly retrieved by the optical drive. Preferably, an interrupt subroutine is performed cyclically to perform the rotation speed control procedure.

  • Patent number: 5363946
    Abstract: An automation device for automobile manual shift system, which comprises a shift key to control an intake electric valve to cause a highly compressed air to enter a power cylinder for driving a clutch pump; such automation device is used for replacing the conventional clutch pedal. There are exhausting electric valves, which will be opened upon the accelerator pedal being stepped down so as to have a highly compressed air exhaust out of the power cylinder to pull back the clutch pump, and the shift change is done; the automation device also comprises a shift-removing key for clearing the shift set if necessary.
