Title: A braked castor
Inventor: SCREEN STAFFORD
IPC: B60B33/02
Filed: 2001-09-03
Abstract: A braked castor has a body 10 to which one or more wheels (16) is mounted, a stem (36) for fixing the castor to an article and being rotatable relative to the body, a carriage 62 which can slide relative to the body, and a pivotable actuator 92 for moving the carriage. In one condition of the sliding part and carriage the castor wheel and stem are free to rotate and in another condition at least one of these movements is locked and the actuator resists movement of the carriage from its locked position. The actuator may have a cam surface which co-operates with a corresponding formation on the carriage. The carriage may be spring-biassed to its free position. Locking may involve engagement of teeth 84,85 on the carriage with corresponding teeth on the stem and wheel respectively.

Title: Musical instrument sound detection
Inventor: HODDER BENJAMIN
IPC: G10H3/18
Filed: 2002-01-09
Abstract: A pickup for a guitar or the like comprises a fibre optic acoustic sensor 160. In one embodiment the fibre is in the form of a coil. A laser pump emits pulses of electromagnetic different frequencies at different times. Acoustic waves falling on the fibre causes changes in its refractive index and thus changes in the interference between the two frequencies. In another embodiment the fibre is erbium doped and provided with two Bragg gratings thereby forming either a Distributed Feedback (DFB) fibre laser or a distributed Bragg reflector (DBR) fibre laser. Acoustic waves cause changes in the length of the fibre and thus a shift in the wavelength of the laser light. A third embodiment makes use of a Mach-Zehnder interferometer (MZI) with an acousto-optic modulator (AOM) in each limb of the MZI.

Title: Printer with vacuum platen having selectable active area
Inventor: SMITH DAVID E
IPC: B41J11/00
Filed: 2002-01-24
Abstract: A printer 10 with a media transport has a rigid, air-transmissive platen 60. A movable air-transmissive flexible web 24 overlies the platen 60 and moves along a feed axis 36. A suction device 22 communicates with the platen 60 to draw air through the web 24 and through the platen 60 so that a sheet of media 42 carried on the web 24 is biased toward the platen 60. A manifold 20 underlies the platen 60 and has a number of separate chambers 76,78 open to the platen 60, so that the suction device 22 is connected to each of the chambers 76,78. Controllers 82 operate to selectably prevent communication between the suction device 22 and at least some of the chambers 76,78. This arrangement stops air being draw in areas which bypass the sheet.

Title: Surface Microfilter
Inventor: HOLDICH RICHARD GRAHAM
IPC: C23C18/32
Filed: 2002-02-07
Abstract: A surface microfilter membrane comprises a lamina substrate possessing through pores having a filtering dimension of no more than 10 microns; the surface of the pores being formed by a metallic plating. The metallic plating may be of nickel or nickel alloy and formed on a metal or plastic substrate. Preferably, the substrate is in the form of a net, the membrane is formed by bending and the pore openings are non-circular (e.g. slotted) in shape. A method of making the surface microfilter includes reducing the pore size of the substrate by coating it with a metal; this method forms non-tortuous pores in a seive type microfilter. Electroless plating is preferred wherein a solution is passed though the substrate under a pressure difference; ultrasonic energy may also be applied to remove gas bubbles from the pores.

Title: A method of constraining a heterogeneous permeability field representing an underground reservoir by dynamic data
Inventor: LE RAVALEC-DUPIN MICKAOLE
IPC: G01V1/28
Filed: 2003-07-10
Abstract: A method of constraining a stochastic model of Gaussian or related type, representing a porous medium such as an underground reservoir, to data characteristic of the displacement of the fluids. The method is based on an iterative development in two stages. The first one consists in carrying out a flow simulation, in identifying zones inside the reservoir and in estimating the modification to be brought to the effective permeabilities of these zones so as to improve calibration between the real data and the corresponding responses obtained with the flow simulator. The second stage involves an intermediate optimization problem intended to minimize an intermediate objective function (implemented from a gradual deformation technique) measuring the difference between the effective permeabilities calculated for the zones and the effective permeabilities identified during the first stage for better calibration. This intermediate optimization allows to propagate the desired modification at the level of the effective permeabilities of the zones to the absolute permeabilities of the whole of the reservoir grid cells. It is possible, during the second stage, to disturb several times the reservoir model without having to carry out flow simulation. Applications include oil reservoirs development for example.

Title: Method for performing a square root operation
Inventor: EBERGEN JOSEPHUS C
IPC: G06F7/552
Filed: 2004-05-07
Abstract: One embodiment of the present invention provides a system that performs a carry-save square root operation that calculates an approximation of a square root, Q, of a radicand, R. The system calculates Q by iteratively selecting an operation to perform based on higher-order bits of a remainder, r, and then performs the operation. This operation can include subtracting two times a square root calculated thus far, q, and a coefficient, c, from r, and adding c to q. During this operation, the system maintains r in carry-save form, which eliminates the need for carry propagation while updating r, thereby speeding up the square root operation. Furthermore, the selection logic, which decides what operation to perform next, is simpler than previous square-root implementations, thereby providing a further speedup.
