Title: Method for controlling power source of power source system and device therefor
Inventor: GORDON N G O
IPC: G06F1/26
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To satisfy high speed insertion/high speed swapping requirements, to improve reliability in simple design, and to attain cost down by operating the output control of a reset output logical means according to an output enable control signal, and controlling the power source supply of a reset output logical means according to a control pulse. SOLUTION: When a control pulse(board reset) is inactive in a power-up sequence, power supply to a reset output logical circuit 25 is controlled by a power source control circuit 20, and a reset(RESET) output is turned into a high impedance. The control pulse is made active after a +5V power source reaches a normal level. An output enable control signal from an output enable control logic circuit 40 is made active before the +5V power source reaches a constant level, and the control pulse is made active. Therefore, the reset output logic circuit 25 can be moved from the high impedance output disable state to a RESET output generation enable state after the +5V power source reaches the normal level and the control pulse is made active.

Title: Method and equipment for detecting two-dimensional speed vector
Inventor: MUSHA YOSHINORI
IPC: G06T7/20
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a correct two-dimensional speed vector field by extending a gradient method to be applicable to a plurality of images. SOLUTION: A gradient method is extended such that a plurality of images, e.g. images of R, G and B, obtained at one time can be used as one image. More specifically, a sample quantizing function 102 samples and quantizes the image data from an image-pickup unit 101. First and second frame butter functions 103, 104 select two images at different time from a sequence of dynamic image obtained continuously. Vector pixel generating functions 105, 106 use the R, G, B of a color image as vector elements. An image differentiating function 107 operates the time and space derivatives of image composed of the vector pixels obtained through the functions 105, 106. A speed vector operating function 108 determines an optical flow by solving a recursive operational expression derived by gradient method.

Filed: 1990-11-30
Abstract: PURPOSE:To separate a signal from a noise level and to reproduce practical multilevel recording information by allowing the difference of a modulation degree between respective recording parts to depend on a prescribed value. CONSTITUTION:A reproducing signal processor 40 is provided with an LPF 401 which eliminates the high frequency component of the signal regenerated from a recording medium, a circuit 402 which generates a demodulation clock corresponding to a recording pulse when the information is recorded on the recording medium and a circuit 403 which generates the level of the regenerated signal synchronously with the demodulation clock. Then, when an information bit is reproduced from the waveform of the regenerated signal, the size of the regenerated signal from a non-recording part is set to be (a) and the regenerated signal of respective recording marks where the multilevel information is recorded is set to be (b). The multilevel information is reproduced by detecting the signal so as to make the difference of the modulation degree between the respective recording levels >=5% when the modulation degree at that time is set to be the absolute value of (a-b)/(a).

IPC: G02F1/1365
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To make a liquid crystal display device possible to display with high quality while preventing the generation of colors due to the change of visual field at the time of displaying white color, by forming plural liquid crystal layers whose layer thicknesses are different in one pixel. SOLUTION: In this liquid crystal display device 21, one pixel 22 is formed out of first and second subpixels 23, 24 and layer thicknesses of first and second liquid crystal layers 25, 26 forming these pixels 23, 24 individually are different. Concretely, since a printed thin film is protrudingly provided in the inner surface of an upper glass substrate at positions of the subpixels 23, 24, the layer thickness of the second liquid crystal layer 26 to be positioned here is made thinner than that of the first liquid crystal layer 25.  Since layer thicknesses of the liquid crystal layers 25, 26 are made different in such a manner, transmissivities with respect to the wavelength of a transmission light are different and the wavelength-tranmissivity obtained by averaging wavelength-transmissivities of the first and second subpixels 23, 24 is made to be the wavelength- transmissivity characteristic of the whole of the pixel 22.
