  • Publication number: 20120265363
    Abstract: The present invention relates to a method of controlling a heat-dissipating fan of a computer device, which is provided with a heat-dissipating fan, a controller, a first sensor unit, and a second sensor unit. The method of the present invention includes the following steps. First, the controller accepts a first signal and a second signal and controls the rotating speed of the heat-dissipating fan according to the first signal. Subsequently, the controller determines the first signal and the second signal. Next, the controller reduces the rotating speed of the heat-dissipating fan corresponding to the first signal to temporarily maintain the rotating speed at a constant to thereby reduce a noise value produced by the heat-dissipating fan.

  • Patent number: 8284235
    Abstract: A method for modifying images for display on a three dimensional display includes receiving a first image and a corresponding second image which together represent a three dimensional image when displayed on the three dimensional display. Based upon the first and second image, the method determines whether their content is expected to cause substantial discomfort to a viewer when displayed on the three dimensional display. At least one of the first and second images are modified based at least in part on a physical value related to the pixel pitch of the display, in such a manner to reduce the expected discomfort to the viewer.
