Title: Energy-conserving power-supply system
Inventor: LEE HOWARD HONG-DOUGH
IPC: G06F1/32
Filed: 1999-02-24
Granted: 2002-03-01
Abstract: An energy-conserving power-supply system utilizes a keep-alive DC power to consistently power a control circuit so as to render a main power supply readily actuatable for either distributing AC power or supplying regulated DC power. The energy-conserving power-supply system allows any one of modern information-processing or entertainment electronic products to be readily operable manually, remotely, or automatically from a standby state; while, it totally eliminates any unnecessary energy waste because AC power is neither transmitted nor wasted not only within but outside the power-supply system. The latter allows an external line-operated device to be concurrently operable from a no-power state, i.e., without consuming any standby energy at all. Not only can the energy-conserving power-supply system conserve energy usage to the greatest extent, it will also correspondingly extend the life spans of electronic circuitry and electromechanical components.

Title: Apparatus and method for describing the motion parameters of an object in an image sequence
Inventor: CHALOM EDMOND
IPC: G06V10/26
Filed: 2000-01-28
Granted: 2001-09-11
Abstract: An apparatus (170) and method for implementing object trajectory segmentation for an image sequence. Specifically, block-based motion vectors for a pair of adjacent frames are used to derive optical flow, e.g., affine, motion parameters. The object trajectory segmenter applies the optical flow motion parameters to form a new prediction or method for predicting the positions of all the points on an object over time within an interval. The new prediction is then applied and the result is compared with an error metric. The results from such comparison with the error metric will dictate the proper intervals (temporal boundaries) of the image sequence at which the motion parameters are valid for various key objects.

Title: Method of manufacturing active matrix substrate
Inventor: HANAZAWA YASUYUKI
IPC: G02F1/136
Filed: 2000-04-14
Granted: 2002-09-01
Abstract: This invention provides a method of manufacturing an active matrix which uses a thin film transistor as a switch device. To manufacture the active matrix substrate, a metal film is formed on a glass substrate. The metal film has a first region and a second region, which lie between other regions of the metal film that will be gate lines and auxiliary capacitance lines. The first and second regions are removed in a process of making, in the metal film, through holes achieving ion doping. Thereafter, the metal film including the first and second regions is patterned, thereby forming gate lines and auxiliary capacitance lines. Hence, the first and second regions of the metal film are etched twice, without increasing the number of steps of manufacturing the active matrix substrate. The probability of short-circuiting between any gate line and the adjacent auxiliary capacitance line is therefore low.
