Title: Cell searching in a cdma communications system
Inventor: NYSTROM JOHAN ANDERS
IPC: H04B/
Filed: 1998-08-29
Granted: 2000-06-11
Abstract: A special coding scheme is disclosed for more effectively acquiring a long code and frame timing during a cell search in a CDMA communications system.  A code set of length M Q-ary code words including symbols from a set of Q-short codes is defined with certain properties.  The primary property to be satisfied is that no cyclic shift of a code word yields a valid code word.  The other properties to be satisfied are that there is a one-to-one mapping between a long code message and a valid code word.  And a decoder should be able to find both the random shift (thereby implicitly finding the frame timing) and the transmitted code word (I.e., its associated long code indication message) in the presence of interference and noise, with some degree of accuracy and reasonable complexity.

Granted: 2002-10-01
Abstract: A computationally efficient method for minimizing the visible effects of texture LOD transitions across a polygon. The minimization is accomplished by adding a dithering offset value to the LOD value computed for each pixel covered by a graphics primitive to produce a dithered pixel LOD value. The dithering offsets mat be generated from a table look-up based on the location of the pixel within a span of pixels. The dithered pixel LOD value is used to as an index in the selection of a single LOD texture map from which a textured pixel value is retrieved. The range of dithering offset values can be adjusted by modulating the values in the table look-up.

Abstract: The present invention relates to a measurement method and device of capacitance for manufacturing capacitor, wherein the relationship between the surface area of thin film and the height of hemispherical grain on the thin film surface is utilized to monitor the area variation of the thin film, so as to obtain the desired capacitance value close to the actual value. The method of calculating the area variation in the present invention is to use the area variation obtained from the height of hemispherical grain t and the porosity fv to measure the capacitance of a capacitor. According to the method, the area variation of thin film can be obtained approximately close to the actual value by measuring the height of the hemispherical grain formed on the thin film surface, and the variation of capacitance can be obtained accurately before completing the capacitor. In addition, the approximate value which is close to the actual value of the surface variation can be monitored in the step of forming hemispherical grain on the thin film surface by the present invention, which has the effect of improving the reliability and productivity of capacitor.

Title: Dynamic pipelining approach for high performance circuit design
Inventor: JOU JE-MIN
IPC: G06F17/00
Filed: 1999-05-14
Granted: 2001-06-23
Abstract: Pipelining is a well-known efficient technique for optimally designing high performance digital circuits. However, conventional pipelining techniques are difficult to pipeline the execution of a loop with variant iteration execution lengths in a circuit. The invention presents a new pipeline design approach, called dynamic pipelining, to design and pipeline this kind of loop in a circuit efficiently. Instead of assuming a fixed latency (or data initiation interval), the approach pipelines the loop using run-time determined latencies to achieve a high performance. The general controller architecture of it is also introduced. It consists of two interactive finite state machines to allow the pipeline datapath to execute at variant latencies. Experimental results show that the approach can obtain about 2 times speedup with acceptable area overhead.

Title: Binart controller for crystal body
Inventor: ONOUE SHUJI
IPC: C30B15/22
Filed: 1999-10-15
Granted: 2002-11-01
Abstract: A binary controller for a crystal body used for a single crystal pull-up production method represented by the Czochralski method for converging the crystal growth diameter and the seed lift speed to their desired values. The seed lift speed controlled variable (SLC) and the temperature controlled variable (TC) are generated independently of each other on the basis of the deviation signal (DEV) of the diameter control parameter. As a result, the seed lift speed acts on the convergence of the crystal growth diameter, and the temperature controlled variable suppresses the variation of the shortage of heat energy and converges the seed lift speed varied by the convergence action of the crystal growth diameter. Hence the binary control of both the crystal growth diameter and the seed lift speed are preferably achieved.
