20080212037 | MINIATURE COLOR DISPLAY APPARATUS - A miniature color display apparatus are disclosed. In accordance with an embodiment of the present invention, the miniature color display apparatus can include N light sources, emitting each two-dimensional color beam of light, N is a natural number and is the same as or larger than 3; a path adjusting material, adjusting an emission path of each color beam of light to allow each color beam of light emitted from the N light sources to be emitted though the same path; an optical modulator, optically modulating each incident color beam of light according to light intensity information; and a beam converter, converting the two-dimensional color beam of light to a one-dimensional color beam of light to allow each color beam of light having the emission path adjusted by the path adjusting material to be one-dimensionally incident on the optical modulator. | 09-04-2008 |
20080266862 | ILLUMINATION OPTICAL APPARATUS - Disclosed is an illumination optical apparatus that can enlarge a beam divergence angle. In accordance with an embodiment of the present invention, the illumination optical apparatus can include a light source, emitting a beam of light in a predetermined direction at a beam output point; a ball lens, arranged in a forward direction of the beam of light emitted from the light source; and a condensing lens group, condensing the beam of light which has passed through the ball lens on a predetermined point. With the present invention, the size and the volume of the illumination optical apparatus can be reduced by enlarging the beam divergence angle by further including a ball lens. | 10-30-2008 |

20080225182 | ANALOG TELEVISION DEMODULATOR WITH OVER-MODULATION PROTECTION - Various embodiments are described herein for a universal television receiver that is capable of processing television channel signals broadcast according to a variety of analog and digital broadcast standards. An overmodulation handling mode is used that modifies operation when locking onto a picture carrier signal frequency in the presence of overmodulation. | 09-18-2008 |
20130223572 | DIGITAL SIGNAL PROCESSOR WITH ADJUSTABLE DATA RATE AND METHODS THEREOF - As a digitized representation of an intermediate frequency television signal moves through a demodulator it undergoes a number of processes, including conversion from an analog signal to a digitized data, digital signal processing of the digitized data, and the like. The rate at which the digitized data moves through the digital signal processor of the demodulator for processing is referred to as the data rate of the DSP. The demodulator can vary the data rate based on a selected television channel, thereby reducing the level of interference at the demodulator resulting from noise. | 08-29-2013 |
