Filed: 1998-12-03
Granted: 2000-08-01
Abstract: This invention can block erasing memory devices, which provide small capacity and low power consumption. The solution is that in order to access the mapping relation between the logical addresses and the physical addresses of the memory grid array 1, the address change table with the corresponding relation and the block table with the empty blocks are memorized in the random blocks of the memory grid array. The physical address is found and its data is read with reference to the address change table during reading data in the memory grid array 1. Additionally, whenever a data is written, the empty block is determined from the empty block table stored in the memory grid array;, and is written with the data. Furthermore, the updated address change table and the empty block table are written into the empty block table.

Title: Search window delay tracking in code division multiple access communication systems
Inventor: POPOVIC BRANISLAV
IPC: H04B1/711
Filed: 1999-04-07
Granted: 2001-04-01
Abstract: The present invention provides a search window delay tracking procedure for use in a multipath search processor of a CDMA radio receiver. A channel impulse response is estimated for a received signal containing plural paths, each path having a corresponding path delay. A search window defines a delay profile that contains the plural paths of the received signal. A mean or average delay is calculated for the estimated channel impulse response (CIR), and an error is determined between the mean CIR delay and a desired delay position corresponding to the center of the CIR search window. An adjustment is made to reduce that error so that the center of the search window and the mean CIR delay are aligned. The error may be processed either linearly (in one embodiment) or non-linearly (in another embodiment) to minimize the error and to reduce an influence of noise. A non-linear filtering process includes calculating a delay spread from the mean CIR delay calculated for successive processing cycles of a window delay tracking procedure corresponding to each new input. A difference is determined between the successive delay spreads. Adjustment signal is set equal to the error signal if the difference is less than or equal to a threshold. Alternatively, the adjustment signal is set to zero if the difference is greater than the threshold. Consequently, if the delay spread in the current iteration is significantly different from the delay spread in the previous iteration, the new error sample calculated in the current iteration is considered unreliable, and no adjustment is made.

Title: Motor
Inventor: NITTA ISAMU
IPC: H02K15/12
Filed: 1999-09-01
Granted: 2002-04-11
Abstract: A split stator core is formed of three unit cores placed adjacent to one another with a minute space in-between. Because magnetic fluxes passing through the respective adjacent portions of unit cores are substantially the same, the number of salient poles is a positive integral multiple of the number of winding phases. The number of winding phases is set to 3 and the number of salient poles is set to 3. As a result, magnetic noise is prevented by such a structure. The adjacent parts of each unit core adjacently arranged in a ring shape are supported by a holding space member made of an electrically insulating material or by the supporting frame made by embedding each unit core in the electrically insulating material, thereby providing an electrical insulation between the adjacent parts of unit cores, so as to reduce the core loss.
