Patent TW-521241-B (TW)
Title: Liquid crystal display apparatus, its driving method, and liquid crystal display system
Inventor: KITAGAWA HIDEYUKI
IPC: G09G3/36
Filed: 2000-03-02
Granted: 2003-02-21
Abstract: The first invention of the case is to improve a defective picture, wherein an optical domain is formed at the corner of the opening portion due to the polarity difference of the image signals written into the adjacent right and left pixels in point inverse driving such that the opening ratio of a pixel is lowered and its transmittance is decreased. In an active matrix type TFT liquid crystal display device of a point-sequential driving system, gate lines Vg1 to Vg5 are snake-wired between the pixels of the upper/lower lines; a Cs line is wired in the state of a matrix; video signals video 1 and 2 of mutually opposite polarity are simultaneously written in pixels of different upper/lower lines; adjacent right and left pixels are the same in their polarity while the upper and lower pixels are opposite to each other in their polarities in a pixel array after writing. The second invention of the case is to realize a two-step precharge even when a graphic display standard with a short horizontal blanking period for a video format is used. In the active matrix type TFT liquid crystal display device by a dot-sequential driving method, sampling switches Pb1A to Pb4A and Pg1A to Pg4A in two series are connected among each signal line sig1A to sig4A arranged for every line, a precharge signal line 18-1A for inputting a black level precharge signal Psig-black, and the precharge signal line 18-2A for inputting the gray level precharge signal Psig-gray. Additionally, for every signal line of Sig1A to Sig4A, the black level precharge signal Psig-black and the gray level precharge signal Psig-gray are successively written, and then the video signal video is written.

Filed: 2000-03-14
Granted: 2001-10-01
Abstract: To provide an electronic watermark method and system for which the detection reliability of embedded information does not depend on the strength of signals that are measured in frames. To achieve the above object, information is prepared for embedding as a bit stream, the sign of the bit stream being changed in accordance with a sign inversion cycle, and the bit stream being embedded in a frame. As for detection of information, values obtained through observation of frames are accumulated, and the accumulated values are compared with threshold values that are varied in accordance with the accumulated values obtained by observation. The comparison results are then employed to detect the embedded information.

Patent TW-515199-B (TW)
Title: Method and apparatus for efficient video processing
Inventor: PRAKASH ADITYO
IPC: H04N7/26
Filed: 2000-07-10
Granted: 2002-12-21
Abstract: A video compression method and apparatus is disclosed. The present invention includes a ""smart"" or active decoder that performs much of the transmission and the instructional burden that would otherwise be required of the encoder, thus greatly reducing the overhead and resulting in a much smaller encoded bitstream. Thus, the corresponding (i.e., compatible) encoder of the present invention can produce an encoded bitstream with a greatly reduced overhead. This is achieved by encoding a reference frame based on the structural information inherent to the image (e.g., image segmentation, geometry, color, and/or brightness), and then predicting other frames relative to the structural information. Typically, the description of a predicted frame would include kinetic information (e.g., segment motion data and/or associated residues representing information in previously occluded areas and/or inexact matches and appearance of new information, and portion of the segment evolution that is not captured by motion per se etc.). Because the decoder is capable of independently determining the structural information (and relationships thereamong) underlying the predicted frame, such information need not be explicitly transmitted to the decoder. Rather, the encoder need only send information that the encoder knows the decoder cannot determine on its own.

Title: Display lamp
Inventor: KAWASHIMA TOKIO
IPC: F21S8/04
Filed: 2000-05-22
Granted: 2003-10-21
Abstract: Since a number of LEDs are required in a display lamp that comprises a light source comprised of LED (light emitting diode), the present invention is aimed to provide an LED display lamp which uses reduced number of LEDs while securing visibility by making efficient use of the light from the LEDs. To this end, with Figure 2 as an example, a display lamp 2 comprises an arcuate (like gutter mounted along an eave) globe 5 surrounding a front surface 2c of a flat non-display portion 2a and housing light sources 4 therein. The light sources 4 are fixed to a case 3 by a base board 6 and comprises a pair of end LEDs 42, 43 disposed at both sides which sandwich the transverse center. Each LED irradiates lights to the zones of the globe 5 at transversely opposite sides so as to increase the area irradiated by the light. As a result, the number of the LEDs required for the display lamp 2 is reduced. Moreover, the center of the globe 5, at which the irradiation of light is insufficient, can be sufficiently irradiated with the light by a center LED 41 or a reflector 82 to secure visibility. Further, a reflector 81 (see figure 4) redirects light and thus realizing effective utilization of the light.

Granted: 2001-12-11
Abstract: A method and apparatus provide polishing of a semiconductor wafer or other substrate. The apparatus includes multiple wafer carriers provided on the top surface of a table. A semiconductor wafer is seated face-up in the wafer carrier. Each wafer carrier is driven by an electric motor to rotate at a low speed. During operation, each wafer carrier is positioned at a work station where a specified task is performed. The table rotates when the task at each station is completed to move the wafers from station to station. Thus multiple tasks relating to polishing (e.g., buffing and drying) can be carried out in parallel. At one station, a polishing pad is positioned by a polishing pad carrier face-down to polish the surface of the semiconductor wafer. A motor drives the polishing pad to move in a high-speed circular motion.

Abstract: To analyze faults occurring in a semiconductor device, an expectation function is derived from bitmap data produced by a tester which is for the semiconductor device. The expectation function represents a distribution of the fault bits and has factors including a predetermined factor. On the basis of the expectation function, it is judged whether or not the distribution of the fault bits has a regular profile. If the distribution of fault bits has a regular profile, by the use of the predetermined factor, a period of the regular profile is automatically provided as an additional parameter to interpret the regular profile and to identify what causes the faults.
