| 20110309717 | TWO-DIMENSIONAL COMB-DRIVE ACTUATOR AND MANUFACTURING METHOD THEREOF - A two-dimensional comb-drive actuator and manufacturing method thereof are described. The two-dimensional comb-drive actuator includes a supporting base, a frame and a movable body. The supporting base has first comb electrodes and the frame has internal comb electrodes and external comb electrodes. The external comb electrodes of the frame are interdigitated to the first comb electrodes of the supporting base. The movable body has second comb electrodes which are interdigitated to the internal comb electrodes of the frame. The thicknesses of the second comb electrodes of the movable body are unequal to the internal comb electrodes of the frame and the external comb electrodes of the frame are unequal to the first comb electrodes of the supporting base. The two-dimensional comb-drive actuator utilizes a conducting layer for the above-mentioned comb electrodes in order to increase the rotation angle and operation frequency thereof. | 12-22-2011 |
| 20090034087 | HEAD-UP DISPLAY SYSTEM - A head-up display system is described. The head-up display system includes an image projection device, a diffusion unit, and a frame demonstration medium. The image projection device emits the visible light, containing text or image information, for generating a real image on the diffusion unit. The frame demonstration medium receives the visible light reflected from the diffusion unit. By adjusting the received visible light reflected from the diffusion unit, the frame demonstration medium generates a virtual image corresponding to the real image. The distance between the real image corresponding to the diffusion unit and the frame demonstration medium is preferably equal to the distance between the virtual image and the frame demonstration medium. Alternatively, the visible light is projected to the frame demonstration medium and then reflected to the diffusion unit. The frame demonstration medium again reflected visible light from the diffusion unit to generate a virtual image corresponding to the real image. | 02-05-2009 |
| 20080278783 | STABILIZING OSCILLATION AMPLITUDE OF TORSION OSCILLATOR AT PREDETERMINED FREQUENCY - A control method of stabilizing the oscillation amplitude of a torsion oscillator is described. The method includes the steps of: driving a torsion oscillator at a predetermined frequency with a drive energy level by a control module to generate a scanning angle of the incident light beam, wherein the drive energy level is associated with the predetermined frequency; comparing the scanning angle corresponding to the drive energy level with a designate scanning angle by the control module; and adjusting the drive energy level based on the comparison result until the scanning angle of the torsion oscillator is equal to the designate scanning angle. | 11-13-2008 |
