Title: Method and apparatus for verifying static signatures using dynamic information
Inventor: KASHI RAMANUJAN S
IPC: G06T7/00
Filed: 1997-12-18
Abstract: In a process of signature verification, an off-line test signature is compared to one or more on-line reference signatures. Dynamic data obtained fromthe reference signature or signatures may be used to improve the thinning of the test signature. Such data may also be used for segmenting the test signature and sequencing the resulting strokes. In some embodiments, the invention includes evaluating a dynamic error, based at least in part on such sequencing of the test signature. In some further embodiments, the invention includes producing a rendering of at least one on-line reference signature as a two-dimensional image, and evaluating a static error based, at least in part, on shape-matching between therendered image and the test signature.

Title: Coin validator
Inventor: BELL MALCOLM REGINALD HALLAS
IPC: G07D5/08
Filed: 1996-04-02
Abstract: A coin validator (1) is provided with at least two reference positions (U, D) for determining a diameter related characteristic of a coin being validated. In order to reduce the running to the testing station, the timing of a trailing point of the coin passing a first reference position (U) is used to determine the diameter related characteristic. Embodiments using optical (6, 8, 9, 11, 30, 32), inductive (50, 51, 52) and piezo-electric (55) sensors associated with the reference positions are disclosed. An inductive sensor (12) for a coin validator comprises an elongate coil, which, when in use, is arranged such that the magnetic field is substantially constant across the width of the passageway. The use of coils of this type have the advantage of wrap around coils but enable the coin passageway to be shallower and be opened. A coin validator (1) is described wherein the backwall of a coin passageway (2) is movable to and fro so that the depth of the coin passageway (2) can be adjusted. In an embodiment, a cam (63) bears against the backwall (62) of the coin passageway (2) to set the depth thereof.

Title: Nucleic acid encoding gai gene of arabidopsis thaliana
Inventor: RICHARDS DONALD ERNEST
IPC: C12N15/00
Filed: 1997-02-12
Abstract: The GAI gene of Arabidopsis thaliana has been cloned, along with mutant and homologue gene sequences. Expression of such genes in plants affects characteristics of the plants including growth. GAI  expression inhibits growth of plants, which inhibition is antagonised by gibberellin (GA). Expression of gai mutants confers a dwarf phenotype which is GA-insensitive. Manipulation of expression of GAI and gai genes in plants results in tall or dwarfed plants. Dwarf plants are useful in particular for reduction in crop losses resulting from lodging.

Title: Cylinder color printing method and product using improved misregistration detection
Inventor: DELLI VENNERI NICOLA
IPC: G09F3/10
Filed: 1998-08-14
Abstract: A method of printing multi-color images on pressure sensitive labels carried on a web uses a disk shaped mark for each color which is printed to form the image.  The disks (spots) are printed on the image, or elsewhere on the top layer of the web, with one disk being printed on top of the other, so that the marks coincide in size, shape and position.  If a color is misregistered, it appears as a crescent which extends beyond the multi-colored disk.  Such misregistration may be immediately viewed on a video magnifier, using at least 400X magnification, and the misregistration corrected.

Abstract: Methods and apparatus that blend graphics data.  In a printing device, a first object is received and rendered into a frame buffer; a second object including blending instructions is received for blending with the first object; and rendered data associated with the first object is retrieved from the frame buffer and a blend of the two objects is rendered according to a user-selectable blending algorithm.  The frame buffer may be a deep frame buffer. The blended data printed may be of a bit depth reduced from that of the frame buffer.  The reduced bit depth may be achieved by halftoning the blended data.  The blending algorithm may be transparency, shadow, overprinting, darkening, lightening, screen effect or additive effect. The blending instructions may include a blend operator defining a blend algorithm for blending two objects.  In another aspect, a printing device includes an interpreter for receiving object data associated with a background and a foreground of an image; a render engine for rendering object data; a frame buffer for storing rendered data; and a blend processor for retrieving rendered data from the frame buffer and for blending it with rendered data from a foreground object prior to printing.

Title: Detection of water constituents
Inventor: TORKILDSEN BERNT HELGE
IPC: G01N23/12
Filed: 1997-08-01
Abstract: A method of calculating the salt content of water in a multiphase flow which comprises irradiating a body of the multiphase flow with radiation of three distinct energy levels; measuring the intensity of the transmitted radiation at each of the energy levels; and using the measurements of transmitted radiation as obtained from calibration and radiation mass attenuation coefficients for hydrocarbons for each of the energy levels, to calculate a unique function representing the salt content of the water. The three energy levels can as an example be provided by the radioactive isotope Barium 133 and the radiation mass attenuation coefficients for hydrocarbons can be calculated theoretically or derived from static calibration measurements. The invention is particularly suited for the measurement of water salinity in a stream comprising a mixture of oil, water and gas, i.e. a multiphase flow, without separating the phases. It is required to accurately determine the water phase salinity and to use the measurement to calibrate the other sensors or measuring equipment. In addition the water salinity is often of interest to the well operators as an absolute value which may then be compared with other wells or monitored over a period of time.

Title: Agonist-dependent internalization of human somatostatin receptors types 1-5
Inventor: PATEL YOGESH C
IPC: A61K51/08
Filed: 1997-08-20
Abstract: The present invention relates to the uses of human somatostatin receptors types 1-5 in the diagnosis and/or treatment of diseases and more particularly to tumor cells, e.g. breast cancer and in cases of Alzheimer's. The present invention relates to (i) recombinant host cells (CHO-Kl cells) individually expressing the 5 hSSTR subtypes; (ii) the use of these cells as tools for testing the ability of synthetic SST agonists or antagonists to induce receptor internalization or upregulation; (iii) the use of the internalization property of hSSTR subtypes to target tumors for selective targeted destruction. For instance, subtypes such as hSSTR3 and 5 which are extensively internalized could be targeted with selective .alpha. or .beta.-emitting SST  radioligands for radiotherapy of, for example, breast cancers which display a rich concentration of these receptors; (iv) the use of the ability of hSSTR1 (in particular) and hSSTR2 and 4 (to a lesser extent) to be upregulated at the cell surface upon prolonged treatment with agonist as a test for increasing the sensitivity of receptor scans for detection and diagnosis of tumors and inflammatory conditions; (v) the use of the differential ability of the hSSTR  subtypes to be upregulated or internalized as a means for producing enhanced images in receptor scans by subtraction analysis to recruit, for example, SSTR1 selective to the membrane whilst internalizing others such as hSSTR3, hSSTR4, and hSSTR5.

Title: Hydrostatic shoe for controlled crown roll
Inventor: ALFANO JAMES P
IPC: F16C13/00
Filed: 1997-07-18
Abstract: A controlled crown roll utilizes a crown support piston (76) with a glide shoe (78) with a cavity (80) in the face of the glide shoe centered under the nip loading line. The cavity is surrounded by a land area (83), the majority of which is located away from the nip load. Use of a low vis-cosity hydraulic fluid, for example, 15.6 cP, with a hydraulic film thickness of 0.002 inches, results in significantly lower fric-tion between the glide shoe and the interior surface (40) of the rotating mantle. Re-cesses in the piston sides form hydrostatic thrust bearings (82) which perform the cen-tering function for the piston and the glide shoe.
