Patent TW-483050-B (TW)
Title: Semiconductor structure
Inventor: RAMDANI JAMAL
IPC: H01L21/20
Filed: 2001-02-09
Granted: 2002-04-11
Abstract: High quality epitaxial layers of compound semiconductor materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates, strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline compound semiconductor layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer.

Granted: 2002-07-11
Abstract: A device and method for calibrating linear velocity and track pitch for optical disc is disclosed. The device comprises a frequency divider, a Synchronous Bit-Clock generator, a bit counter and a linear velocity and track pitch calculator. The frequency divider receives a motor frequency generator (FG) pulse and generates a motor rotation period signal (FG/X). The Synchronous Bit-Clock generator generates high frequency Bit-Clock according to Reproduced signal from disc. The bit counter counts the pulse of the Bit-Clock for each period of the motor rotation period signal and generates data amount M. The linear velocity and track pitch calculator calculates the linear velocity by a linear velocity function with the information of the data amount M and the motor rotation period. Then, the linear velocity and track pitch calculator calculates the track pitch by a pitch function with the information of the data amount, radius and linear velocity at different tracks.

Title: Method and apparatus for puncturing code symbols in a communications system
Inventor: LUNDBY STEIN
IPC: H03M13/00
Filed: 2001-06-01
Granted: 2004-11-21
Abstract: Techniques for puncturing symbols in a communications system. S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. A number of puncture distances, D1 through DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. P1 through PN symbol punctures are then performed at the distances of D1 through DN, respectively. For a more even distribution of the symbol punctures, each of the distances D1 through DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as Dmin=[S/P], where [] denotes a floor operator. The symbol punctures at each computed distance can be performed together or distributed with symbol punctures at other distances.

Title: Apparatus and method for detecting defects in a multi-channel scan driver
Inventor: BIELSKI SCOTT A
IPC: H04N17/00
Filed: 2001-07-11
Granted: 2006-01-21
Abstract: A technique is described for detecting defects such as short circuits in a device such as a discrete pixel detector used in a digital x-ray system. The technique employs test circuits associated with each row driver of the detector. The test circuits are enabled by a test enable input signal, and the row driver sequentially enables the rows of the detector, along with the individual test circuits. In a test sequence, output signals from the row test circuits are monitored to identify whether a defect, such as a short circuit, is likely to exist in the row or row driver. The test circuitry adds only minimal area and complexity to the row driver function, providing a high degree of test coverage at a low cost, with minimal likelihood of test circuitry-induced failures.

Title: Single-stage PFC+ballast control circuit/general purpose power converter
Inventor: NADD BRUNO C
IPC: H05B41/392
Filed: 2002-03-21
Granted: 2003-11-21
Abstract: Two switching half-bridges are operated to achieve constant power delivered to a resonant load while achieving a high power factor. A half-bridge connected to a circuit input draws a sinusoidal current that is in phase with the input voltage to achieve the high power factor. The two half-bridges are composed of two switches each, which are operated to obtain constant load power in satisfaction of calculated conduction angles. Alternatively, the switches are operated on complementary 50% duty cycles to regulate output voltage and shape the input current waveform. Output regulation is achieved by frequency control while input current wave shaping is realized by phase shifts between the two half-bridges.
