Title: a direct sequence spread spectrum (ds-cdma) receiver which uses linear equalization with parallel and iterative interference cancellation
Inventor: FRANK COLIN D
IPC: H04B1/7107
Filed: 2002-07-29
Abstract: The present invention provides linear MMSE equalization with parallel interference cancellation for symbol determination in a forward link of a CDMA communication system which has a plurality of code channels in use. Use of the linear MMSE equalization with parallel interference cancellation of the present invention provides significantly increased performance. The preferred method linearly filters a received signal to form a first filtered signal (410), despreads and demodulates the first filtered signal (415, 420) and provides a plurality of symbol estimates for all corresponding code channels (430). An estimated transmitted signal is generated from the plurality of symbol estimates (435), and with a channel estimate (405), an estimated received signal is generated (440). A residual signal is determined as a difference between the received signal and the estimated received signal, is linearly filtered (445), and then combined with the estimated transmitted signal to form a next, enhanced estimated transmitted signal (450 Figure 4B). This next estimated transmitted signal is despread (455, 460 Figure 4B) and utilized to provide a next plurality of symbol estimates, for a selected code channel of the plurality of channels, for subsequent use in error correction and decoding, and further use by a subscriber (465, 475 Figure 4B).

Title: Image correlation system having reduced computational loads
Inventor: NAHUM MICHAEL
IPC: G06K9/64
Filed: 2002-08-05
Abstract: Two images are obtained and correlated only at offset positions corresponding to a sparse set of image correlation function value points 402. One or more correlation value points 402a, 402b, 402c, 402d of the sparse set will have correlation values that indicate that those points lie within a peak portion 420 of the correlation function 400. Once one or more such points are identified, the images are correlated at offset positions corresponding to a second, dense, set of correlation function value points. The correlation function values of these points are then analysed to determine the offset position of the correlation function peak. In other embodiments, after one or two pairs of images are obtained, an auto-correlation function for one of those images is generated to determine a smear amount and possibly a smear direction. The smear amount and direction are also used to identify potential locations of a peak portion of the correlation function between the pair of images. The pair of images is then correlated only at offset positions corresponding to the one or more of the potential peak locations.

Title: Fire extinguishing nozzle with non-radial outlets
Inventor: DUNSTER ROBERT GEORGE
IPC: A62C31/05
Filed: 2002-11-28
Abstract: A fixed fire extinguishing nozzle has a body 101 with a central cavity 103 from which a plurality of fluid outlets 109B extend. The outlets extend non-radially with respect to the central axis 135 of the cavity 103, i.e. at least a portion of each outlet is inclined with respect to any plane parallel to and passing through the central axis of the cavity which intersects the portion of the outlet. The extinguishant from the non-radial outlets 109B is thrown towards the walls of the chamber 139, along the paths 141. The jets of the fluid induce a rotational movement within the ambient fluid (for example, air) already present in the chamber, thus creating a vortex or rotational movement of the fluid within the chamber 139, in which the fire exists. The non-radial outlets may be at 45{ to the radius, Fig 5, or tangential (Fig 7) or in the form of a tube (Fig 12) with a radial portion (M) followed by a non-radial potion (O).

Title: Magnetic sensor with suppressed side reading
Inventor: HASEGAWA NAOYA
IPC: G11B5/39
Filed: 2003-04-17
Abstract: A magnetic sensor includes a free magnetic layer 28 with ferromagnetic layers 30 formed on either side portion A, B. Antiferromagnetic layers 31 are formed over the ferromagnetic layers 30. The layers 30, 31 are configured so that distance C is greater than distance D and the ferromagnetic layer 30 extends further towards the centre of the sensor in the track width direction (x) than the inner end surface 31b of antiferromagnetic layer 31. This structure gives good sensitivity in the central portion aligned with the track to be read, but reduced tendency to pick up adjacent tracks to the side. The sensor is therefore suited for narrower tracks used in higher data density media. A method for manufacturing the sensor is also disclosed.

Title: Improved cutting machinery
Inventor: MARSHALL ADRIAN RICHARD
IPC: B26D1/46
Filed: 2003-04-29
Abstract: Food products 9 such as cheese are cut using a tensioned wire 1 moved laterally and reciprocally along its length. A combination of motors 4, 5 and sprung or pneumatic components may control the lateral speed and tension of a cutting wire. The use of lateral motion reduces the force required to cut products, so there is less product damage and finer cutting wires can be used.

Title: Device for purifying fluids, in particular water
Inventor: GRANT JON
IPC: B01D71/56
Filed: 2004-05-24
Abstract: The fluid purification device comprises a cylindrical filter member 12 made of porous plastic material. The filter member is tubular in construction and has an inner longitudinally extending channel 14. The outside surface of the filter member has a chemically treated fabricated nylon resin 30 adhered, or otherwise attached, thereto. The resin is chemically treated by, for example, bonding nylon beads with penta-iodide. Water, or another fluid, which passes through the resin is treated and purified by iodine leaking into the water. Other similar chemicals could be used instead of iodine such as chlorine. Any harmful compounds still in the water after it has passed through the resin are removed by the filter member as it passes into the inner channel. The purified water is safe to be drunk by humans. One end of the filter member 12 may be closed by a removable base member (16, Fig. 1). The base member has incorporated therein an umbrella valve. The base member has a central aperture 18 extending therethrough. The base member may have further apertures in the vicinity of the central aperture and a cap (20, Fig. 4) which has a plurality of small apertures (21, Fig. 4) which allow air to flow down the channel and out through the base member while preventing fluid to flow back thorough the base member into channel 14. In use, fluid contained with channel 14 can flow through outlet (28, Fig. 1) via a stem (24, Fig. 1). A lid portion (26, Fig. 1) may engage with the rim of an outer casing of a water bottle so that the filter member may be encased therein. The water can be accessed from the inner channel 14 by simply sucking on the outlet 28 of the stem 24.

Title: Tubular expansion
Inventor: COOK ROBERT LANCE
IPC: E21B43/10
Filed: 2002-01-02
Abstract: A mono-diameter wellbore casing is formed by plastically deforming and radially expanding a first tubular member 155 within a wellbore 10 using an expansion cone 115 with an over-expansion sleeve 130. The over-expansion sleeve 130 may be made of a frangible or elastic material or be composed of arcuate inserts separated by resilient members. After a predetermined time period and/or a predetermined axial displacement of the cone 115, the over-expansion sleeve 130 is forced off the cone 115 due to the frangible or resilient nature of the over-expansion sleeve. Continued movement of the cone 115 expands the first tubular member 155 by a lesser amount than that provided by the combination of the over-expansion sleeve 130 and the cone 115. A tubular member 200 may then be plastically deformed and radially expanded to form a mono-diameter casing. Other embodiments are described in which the initial expansion is done by an inflatable bladder or a roller expansion device.
