Title: Quantizing phase of speech signal using perceptual weighting function
Inventor: KIM DOH-SUK
IPC: G10L19/093
Filed: 2000-10-05
Abstract: The present invention provides an apparatus and a method for quantizing the phase of a speech signal using a perceptual weighting function. The apparatus includes a phase information extractor (100) for obtaining the phase of each harmonic frequency in a speech signal represented by the discrete sum of periodic signals having different harmonic frequency components, a quantization noise shaping unit (110) for controlling the amount of quantization noise of each phase using a perceptual weighting function, which makes quantization noise less than a predetermined just noticeable difference (JND) of the phase, a quantization bit assigner (120) for assigning quantization bits to each phase according to the controlled amount of quantization noise, and a scalar quantizer (130) for quantizing each phase by the assigned quantization bits. In an alternative arrangement (fig. 2) for vector quantization, the components (120), (130) are replaced by a comparator, a quantization estimation codebook and a minimum value detector. It is possible to improve the quality of encoded speech by quantizing phase information using a perceptual weighting function.

IPC: G01F15/18
Filed: 2001-02-06
Abstract: An electromagnetic flowmeter is configured as an insert (18) for insertion into a pre-existing housing (10) connected in a flow line. The insert is intended for direct replacement of a mechanical flowmeter previously located in the housing. The insert (18) comprises a flow measurement duct (24) of non-magnetic material, magnetic field generating means for generating a field across the duct, and electrodes to detect a voltage induced in the flowing fluid by the magnetic field.

Title: CDMA receivers with subtractive suppression of interpath interference (IPI) and multiple access interference (MAI)
Inventor: FITTON MICHAEL PHILIP
IPC: H04B1/707
Filed: 2002-01-25
Abstract: Spread spectrum receivers for reducing interference are described, particularly the interference observed at a user-end terminal in a W-CDMA 3G mobile communications system. Interpath interference which arises due to non-zero cross and auto correlation of more than one spreading code is suppressed by estimating a transmitted signal stream for a number of CDMA channels and/or multipaths, respreading this estimated signal and subtracting non-orthogonal interference contributions from a received signal before despreading a desired signal. Alternatively the estimated signal streams can be multiplied by the cross correlation between their spreading code and the desired signal spreading code and subtracted from an already despread symbol. The techniques provide an improved bit error rate or equivalently, enhanced capacity for a digital mobile communications network, and is particularly useful for cancelling pilot interference.

Title: Generating a handover decision in response to a desired handover probability in response to a cell load condition
Inventor: CHEUNG COLLEEN
IPC: H04W36/22
Filed: 2003-01-20
Abstract: The invention relates to a system for performing handovers in a cellular communication system. A desired handover probability is determined 303 for a cell (201) in response to a cell load condition which specifically is a relative load of the cell (201). A handover decision is generated 307 by a stochastic process resulting in a decision corresponding to the desired handover probability. The desired handover probability for handovers away from the cell (201) increases for increasing congestion, and the desired handover probability for handovers to the cell (201) decreases for decreasing congestion of the cell. If the handover decision is a decision to perform a handover, this is instigated 311. The process is repeated for a plurality of subscriber units thereby providing a flexible and gradual congestion relief that increases for increasing congestion levels.

Title: Inspection system
Inventor: GIBBONS NIGEL
IPC: G06Q10/00
Filed: 2003-08-08
Abstract: An inspection system has a map (10) showing an area to be inspected, the map being provided on a substrate carrying a non-uniform background pattern (20). The pattern encodes location information at each location. A reading/writing device is used for writing over the map and for reading the background pattern at or adjacent the locations at which the markings are written. Background pattern information is stored for the locations of all written markings; and inspection information is derived from the stored information. In this system, the user is simply required to write over a map showing the area being inspected. The system recognises the location of marks made on the map, and the system can then determine the physical units which have been inspected based on the location of the markings over the page. The system may be used to record information relating to the condition of streetlights (16) along roads (12,14) shown on the map (10).

Title: Integrated diagnostics in a process plant having a process control system and a safety system.
Inventor: SCOTT CINDY
IPC: G05B9/03
Filed: 2004-01-27
Abstract: A process plant includes a safety system 14 that is physically and logically integrated with a process control system 12 such that the safety system and the process control system can use common communication, diagnostic and display hardware and software within the process plant while still providing functional isolation between the safety system controllers 50-56 and the process control system controllers 24. This integrated process control and safety system uses a common data communication structure for both the safety system and the process control system so that applications can send data to and receive data from devices in either system in the same manner, e.g., using the same communication hardware and software. However, the common data communication structure is set up to distinguish process control system devices from safety system devices using tags, addresses or other fields within the messages sent to or received from the devices, which enables data associated with the process control system to be distinguishable from data associated with the safety system, thereby enabling a diagnostic application 82 within a user interface to automatically treat this data differently depending on the source (or destination) of the data.

Title: Circuit and method of a turn-on coil driver for controlling an ignition coil.
Inventor: MORGANTI CARL R
IPC: F02P3/09
Filed: 2004-08-23
Abstract: A circuit for controlling an ignition coil, comprises a coil driver 18 in communication with the ignition coil 30; a first node 12 for receiving a coil control signal; a second node 14 connected to the coil driver; a capacitor 16 in communication with the second node; and a first diode 22, preferably a Zener diode, having its cathode in communication with the first node and its anode in communication with the capacitor for providing a discharge path to discharge the capacitor after the ignition coil has been energized. Preferably a resistor 24 is in communication with the said diode and capacitor. As the capacitor is charged it gradually increases the voltage provided to the ignition coil driver. The rate of increase in voltage is controlled by the selection of resistor and capacitor. The slowing of the voltage supplied to the ignition coil driver has the effect of attenuating the feed forward voltage. Additionally a second resistor 20, which is in communication with the cathode of the said diode and electrical ground, determines the rate of discharge of the capacitor.
