Title: Method and arrangement for automatic gain control of received signals
Inventor: HE NING
IPC: H04B1/707
Filed: 2000-09-05
Abstract: The present invention relates to a code division multiple access (CDMA) communication system, more particularly to an arrangement and a method in a receiver (10) to simplify and improve signal processing in the demodulator (11) of the receiver (10) by means of reducing the long term dynamic range of received signals and, thus, reducing the number of bits needed for coding of said signals. This is accomplished by a signal processing means (16) in the signal input paths in front of the demodulator (11), said means (16) including at least an improved digital AGC-unit (161), which scales incoming signal samples to a common and constant power level, and including a subsequent quantizer unit (162), which transforms the scaled signal samples to samples using a reduced number of bits. Due to this, the transmission bandwidth in the receiver unit is reduced and the signal processing in the demodulator is less complex.

Title: Dust sampling device and method
Inventor: KOGURE NOBUYUKI
IPC: G01N15/02
Filed: 2002-03-11
Abstract: A dust sampling device, and method of use thereof, comprising a nozzle (1) with a variable inlet diameter. The nozzle is inserted into the interior of a flue gas duct and is connected to a dust measuring device. The variable inlet diameter is such that the gas entering the nozzle is at the same velocity as the flue gas in the duct whilst maintaining a constant sampling flow rate. The nozzle may be composed of a stationary nozzle (1) and a slippage nozzle (9); the slippage nozzle preferably being driven by a gear mechanism including a rotary shaft (6) provided with a gear (8) and teeth (7) so that it can be moved back and forth with respect to the stationary nozzle. The nozzle diameter is capable of instantaneous change in response to a change in flue gas duct velocity so as to maintain a constant sampling flow rate and allow isokinetic sampling to be achieved. Examples of measuring devices that may benefit from use with the sampling device are filter oscillation monitors, carbon particle monitors, cascade impactors, multi-cyclones and JIS type dust samplers where large errors are accrued due to non-uniform sampling rates. The sampling device may be particularly useful for measuring flue gas from factories or a vehicle exhaust.

Title: Method of controlling engine torque during a gear shift
Inventor: HEMMINGSEN FRED ROAR
IPC: B60W10/10
Filed: 2002-03-28
Abstract: A method of controlling engine 10 torque during a gear shift comprises applying a load generated by an electric machine 100, eg a starter/alternator to the engine, so that torque transmitted through a clutch 14 is matched to the torque transmitted by the clutch 14, thereby avoiding engine flare. To provide a smooth take up of drive, the torque applied to the engine 10 by the starter/alternator 100 is varied in accordance with the difference between the engine speed and the speed of the clutch 14 driven plate or, for example, an input shaft of a transmission 12. The starter/alternator 100 is controlled by a closed loop feedback circuit which varies a field winding current of the starter/alternator 100. Gears 104, 106 may be used to connect the starter/alternator 100 to a crankshaft 102 of the engine 10, alternatively a belt or chain (114, fig 2b) may be employed. In another embodiment a rotor (202) of the starter/alternator 100 is mounted directly on a drive shaft (204) and it may be a hybrid electrical drive.

IPC: G11C16/34
Filed: 2002-09-27
Abstract: The controller of a non-volatile memory system stores lists of erased and recently erased data blocks in a volatile memory. The lists are transferred to the control data structures in the non-volatile less frequently than the contents of the lists changes, this is to reduce the number of read and write accesses to the memory for control data so as to speed up the write speed of data to the memory system. The controller can reconstruct the block control data from the control data stored in the non-volatile memory at any time. The lists can be transferred to the control data structures in the non-volatile memory at the same time as the other data such as the logical to physical mapping data. Also the controller can use the lists to storage data in blocks that have not been used so as to even out the block usage. Also disclosed is a method of operating a non-volatile memory using the controller.

Title: A method of classifying a set of data
Inventor: ADAMS BARRY DAVID OTLEY
IPC: G06F17/00
Filed: 2002-11-08
Abstract: A two-stage method of classifying a set of data comprises: in a training phase: estimating from pre-classified sets of training data the probability of at least two features occurring together in each of at least two categories; and calculating, from the appropriate estimated probability and a measure of the probability of the features occurring together in the sets of training data if the features were independent, an error factor for the two features for each category. This involves comparing a vector of the estimated probabilities of the features occurring together in each of the categories with a vector of the probabilities, if the features were independent, of the two features occurring together in each category. In a recognition phase, the error factor is used to classify the set of data. The error factor is a measure of the falsehood of the assumption of independence assumed by the Na¤ve Bayes algorithm. Using the error factor in the recognition phase can then correct at least partially for this falsehood, resulting in improved classification of sets of data, compared to the classic Na¤ve Bayes algorithm.
