Title: Video signal decompression system with high efficiency memory access capability
Inventor: CHEN WEN-KUAN
IPC: H04N7/24
Filed: 2000-08-08
Granted: 2002-03-01
Abstract: The present invention relates to a kind of video signal decompression system that has high efficiency memory access capability. The invented system has a memory apparatus for storing the reference picture such that the reference picture can be read to conduct movement compensation when performing the decompression process. The reference picture is stored in the memory apparatus by using the pixel of the horizontal line as a unit. When one horizontal-line pixel of the reference picture can not be completely placed in one column of the memory apparatus, the pixel, which is the same as the pixel of one bulk length at the beginning of the next line, is repeatedly stored at the broken point of the column so as to avoid the broken problem of reading the entire page generated when the memory is read.

Patent TW-496034-B (TW)
Title: Low power mode and feedback arrangement for a switching power converter
Inventor: HWANG JEFFREY
IPC: H02M3/158
Filed: 2001-05-08
Granted: 2002-07-21
Abstract: A low power mode and feedback arrangement for a switching power converter. Two or more main power switches, such as transistors, transfer energy from a supply to load by their opening and closing. When the load requires a relatively low power level, this condition is detected. In response, one or more of the transistor switches is disabled from switching and the reduced power requirements of the load are handled by the remaining one or more transistor switches. As a result, switching losses are reduced. This is because parasitic gate capacitance and on-resistance associated with the disabled switches no longer consume power from the power source. The invention provides significant efficiency advantages during periods when the load draws a low level of power. This is especially useful for battery-powered devices which may operate in a low power mode for extended periods of time, such as standby mode as in a portable telephone. This is because the prevention of power loss in may contribute considerably to operating time before battery re-charging is needed. However, when additional power is required, one or more previously disabled switches may be brought back into play to ensure that the power requirements of the load are met. In an audio amplifier having a H-bridge arrangement for provding a differential output signal, the invention also provides a feedback path from only one side of the load. This reduces distortion associated with open-ended operation.

Title: Improved overlay alignment apparatus and method using polarization schemes
Inventor: YIN XIAOMING
IPC: G03F9/00
Filed: 2001-05-15
Granted: 2002-07-11
Abstract: An optical alignment system used in the manufacture of semiconductor integrated circuits determines and adjusts the alignment between features which have been formed on a semiconductor wafer and features on a mask which is being projected onto the semiconductor wafer. Light which illuminates the semiconductor wafer is scattered and diffracted into a dark-field detector system. This results in the generation of electrical signals which are used to position the mask relative to the semiconductor wafer. The use of polarized light in the present system results in an increase in the magnitude of the desired signals and a decrease in the magnitude of the spurious signals. To improve the quality of the signals, the angle of polarization of the light is adjusted to a specific relationship with respect to the geometry of the alignment marks on the semiconductor wafer.

Title: Air managing systems and methods for gas depolarized power supplies utilizing a diaphragm
Inventor: PEDICINI CHRISTOPHER STEVEN
IPC: H01M8/04
Filed: 2001-06-21
Granted: 2003-05-11
Abstract: Air managers for gas depolarized power supplies such as metal-air batteries or fuel cells are described utilizing a resilient diaphragm moving in one direction by the force of an electromagnetic field and in the opposite direction by the resiliency of the diaphragm. The movement of the diaphragm causes air to be exchanged between the interior of the casing adjacent to the air electrode and exterior of the casing through the ventilation passageway. An electrical circuit may be employed containing a pair of contacts with one of the contacts connected to the diaphragm. The contacts are closed when the current flow through the coil is less than a predetermined level, however, when the current flow through the coil is greater than a predetermined level, the diaphragm moves. As the diaphragm moves, the contacts are opened, thus breaking the circuit, de-energizing the coil, and allowing the resiliency of the diaphragm to return it to the original position and remaking the circuit. The de-energizing and re-energizing of the coil may be repeated to cause the diaphragm to oscillate. The metal-air power supply may have two modes of operation drawing different levels of current from the power supply. In this case, the passageway permits a predetermined low flow rate of air from the exterior to the interior of the casing adjacent to an air electrode of the cell during a low current draw mode of operation while the air mover is inoperative. The air mover, however, becomes operative responsive to the initiation of a high current draw mode of operation.
