Title: Proximity transaction control
Inventor: CASTLE ROBERT JOHN
IPC: H04B5/02
Filed: 2001-07-31
Abstract: A method is disclosed of controlling a proximity transaction between first and second communications devices (P1 and M1), each of which is provided with a short-range transceiver (3, 1). The first communications device (P1) has an RF/ID reader (5), and the second communications device (M1) has an RF/ID tag (6), the RF/ID tag containing the same identifier information as the second communications device. The second communications device (M1) is positioned within the range of the reader (5) of the first communications device (P1). Then, the transceiver (1) of the second communications device (M1) transmits a transaction request and the identifier information of that device to the first communications device (P1). The reader (5) of the first communications device (P1) then interrogates the tag (6) of the second communications device (M1), and the transaction is completed upon the reader (5) of the first communications device (P1) receiving identifier information from the tag (6) of the second communications device (M1) that is identical to the identifier information already received.

Title: Scanner illumination nonuniformity compensation
Inventor: SPEARS KURT E
IPC: H04N1/401
Filed: 2002-03-20
Abstract: A scanner scans a first calibration strip 204 prior to a main document scan in order to determine a first set of gain calibration values required to compensate for nonuniform illumination. After scanning a document 200 a second calibration strip 206 is scanned in order to determine a second set of gain calibration values at the end of the main scan. The calibration values are then used to determine how the image data obtained from the document scan should be corrected to compensate for nonuniformities in illumination detected during the calibration scans. In order to enable this process first and second calibration strips are located on the platen 202 at first and second ends respectively. The compensation process described enables scanning to be carried out without necessarily waiting for the illumination lamp to reach optimum working temperature, as the differences in luminance before and after scanning are accounted for by the calibration steps. A third optional calibration strip is described which may be mounted parallel to scanning direction 222 in order that illumination may be monitored continuously during scanning.

Title: Cleaning water filter using brush, scraper, spray, reverse flow or ultrasound
Inventor: BENENSON JR JAMES
IPC: B01D29/15
Filed: 2002-05-31
Abstract: A water filter for use in a desalination plant has a cylindrical screen 36. A brush 62, scraper or other particulate removing means running the length of the screen is disposed between two confining walls 64A, 64B also running the length of the screen to form a chamber 50. A partition 200 with apertures 212 divides the chamber into two dislodge chambers 50A, 50B and a drain chamber 50C in communication with a drain. During cleaning, the screen is rotated in direction 161 against the brush to liberate screened particulates and a limited amount of water into the dislodge chambers 50A, 50B, through the apertures 212, into the drain chamber 50C and out to the drain. The brush or scraper may be augmented or replaced by a spray (151, Figs 9, 10). The screen 36 is made of wedge wire, wire cloth or perforated metal, and traps particulates as small as 25 microns. Two such filters in parallel are used in series with filters of different porosity, a cyclone separator and a reverse osmosis membrane (Fig 1). Alternative methods of cleaning the screen using reverse flow of clean water and/or an ultrasonic generator are disclosed (Figs 14-18).

Title: Adjusting resource threshold (maximum available resource per terminal) according to cell load
Inventor: DANEEL JEROME
IPC: H04W28/06
Filed: 2002-08-14
Abstract: In a mobile telecommunications network where a base transceiver station carries out two way communication with mobile terminals in a cell and shares resources among the terminals, e.g. Wideband-Code Division Multiple (W-CDMA), a threshold value for resources available per terminal is dynamically adjusted on the basis of cell loading. For example, where the resource is transmit power, the maximum available transmit power per terminal may be varied in inverse proportion to the cell loading, preferably in a stepwise fashion. A further resource may be bit rate, where the availability range for the highest bit rate increases as load decreases (figs. 1, 3). The use of a dynamically adjusted threshold rather than a fixed one enables a better service to be offered to some users when the network has sufficient capacity to accommodate them, e.g. allows admission of new calls, prevents termination or bit rate reduction in existing calls.

Title: Suppressing a background colour in an image
Inventor: SEVIGNY BENOIT
IPC: G06T15/04
Filed: 2002-09-13
Abstract: Apparatus is provided to colour-suppress a source frame that is composed of a plurality of pixels, each pixel being represented by three components defining a position within a colour space. The source frame, comprising a foreground image against a background of a substantially uniform backing colour, is provided to a processing means via an input means. A distance value is defined that for any pixel describes how close its colour is to a specified colour, and the processing means calculates a transformation that maximises the distance value of a selected background pixel. Then, for each pixel, the processing means calculates a transparency value that is a function of the distance value of the corresponding transformed pixel. The transparency value is used to calculate how much of the backing colour should be subtracted. The foreground image can then be composited with a replacement background using the same transparency values.

IPC: G02B5/30
Filed: 2003-02-19
Abstract: An optical element is constituted by a multilayer structure (1) having a periodic structural portion as at least one region constituted by repetition of a predetermined period. An end surface (1a) of the multilayer structure (1) not parallel to layer surfaces of the multilayer structure (1) is used as a light input surface whereas one or each of opposite surfaces (1b) of the multilayer structure (1) parallel to the layer surfaces is used as a light output surface. The periodic structural portion of the multilayer structure (1) can be regarded as a one-dimensional photonic crystal. Refracted light 4, 5 from the one-dimensional photonic crystal has good directivity and the direction of the refracted light 4, 5 has strong dependence on wavelength. When this wavelength dependence property is used, a spectroscopic device or a polarized light separating device of high resolution can be achieved without increase in device size. Transparent parallel plane substrate 2 is shown. Medium M1 may be air.

Title: Multiple processor visibility search system and method
Inventor: SOWIZRAL HENRY A
IPC: G06T15/00
Filed: 2001-11-29
Abstract: A system and method for performing visible object determination based upon a dual search of a cone hierarchy and a bound hierarchy performed by multiple processors. Each processor is configured to read a (global and/or local) problem queue to access a bound-cone pair. The bound-cone pair points to a bound in the bound hierarchy and a cone in the cone hierarchy. The processor computes a bound-cone distance between the bound and the cone, and compares the bound-cone distance to a visibility distance associated with the cone. If the bound-cone distance is smaller than the visibility distance, the processor may write two or more refined bound-cone pairs corresponding to a refinement of the original pair to the global or local problem queue. When the processor detects a leaf bound and a leaf cone, it updates a nearest object pointer and the visibility distance associated with the leaf cone.
