Title: Electronic game method and apparatus with hierarchy of simulated wheels
Inventor: BAERLOCHER ANTHONY J
IPC: G07F17/32
Filed: 1997-03-19
Granted: 2003-03-18
Abstract: A computer implemented electronic game includes a wheel of fortune game with odds of a jackpot greatly in excess of the number of indicia on a simulated wheel. In one embodiment, a virtual mapping allows a bonus indicium of the wheel to be given a 1:M chance of being landed on, even though the bonus position is one of N positions on the simulated wheel. A random number L is chosen between 1 and M and this number is mapped to a number between 1 and N. The display of the wheel if controlled to simulate stopping of the wheel at the 1th indicium where L is mapped to 1. In one embodiment, by using successive wheel spins, the odds of moving to the next round are multiplied to achieve an overall odds of winning a jackpot. In one embodiment there is a 1:50 chance of entering a bonus screen from a main slot machine/phrase completion screen, a 1:20 chance of landing on a bonus position in a first wheel spin, a 1:40 chance of landing on a bonus position for a second wheel spin and a 1:200 chance of landing on a bonus position for a last wheel spin to provide an overall odds of a jackpot of 1:8 million.

Title: Method, reagent and kit for evaluating susceptibility to premature atherosclerosis and treatment of same using gene therapy
Inventor: LIU GUOQUING
IPC: C12Q1/683
Filed: 1995-10-11
Granted: 2007-04-17
Abstract: A single point mutation in the human lipoprotein lipase gene which results i n an A .fwdarw. G nucleotide change at codon 291 (nucleotide 1127) of the lipoprotein lipase gene, and a substitution of serine for the normal asparagine in the lipoprotein lipase gene product is seen with increased frequency in patients with coronary artery disease, and is associated with an increased susceptibility to coronary artery disease, including in particular premature atherosclerosis. This is expressed as a diminished catalytic activity of lipoprotein lipase, lower HDL-cholesterol levels and higher triglyceride levels. Thus, susceptibility of a human individual to premature atherosclerosis can be evaluated by: (a) obtaining a sample of DNA from the individual; and (b) evaluating th e sample of DNA for the presence of nucleotides encoding a serin residue as amino acid 291 of the lipoprotein lipase gene product. Patients found to be suffering from or likely to suffer from premature atherosclerosis and other forms of coronary artery disease as a result of a lipoprotein lipase deficiency can be treated using gene therapy.

Title: Method and apparatus for detecting and identifying microbial colonies
Inventor: BRAIER ROBERT A
IPC: C12Q1/06
Filed: 1995-09-20
Granted: 2008-01-29
Abstract: A method and system for detecting and identifying microbial colonies in an inoculated growth medium first acquires a first image of the inoculated growth medium (100). After a selected incubation time interval (110), a second image of the growth medium is acquired (100). A difference image is produced by taking the difference between corresponding pixels in the first and second images (112). Potential colonies are identified within the difference image by locating peak pixels having local maximum pixel intensities within the difference image and having decreasing gradients in a predetermined number of directions (118). The potential colonies are validated as actual colonies by eliminating those potential colonies that are noise spikes or noise around previously validated colonies (120).

Title: Device for dispensing a volatile active ingredient
Inventor: DANCS IMRE J
IPC: B01F3/04
Filed: 1996-05-08
Granted: 2000-07-18
Abstract: A dispensing device for dispensing a volatile active ingredient from an airtransmitting substrate that forms a part of a refill assembly. The dispensing device includes a housing with an intake vent and an exit vent and an air flow path extending between them. Refill assembly support means are provided for removably supporting the refill assembly with its substrate located in the air flow path. Battery-powered fan means are provided for propelling air from the intake vent through the substrate and out the exit vent. A battery holder holds a fan battery in such a manner that a refill assembly not fully inserted within the refill assembly support means blocks the placement of a battery in the battery holder, while a battery correctly held in the battery holder blocks the removal from the air flow path of a refill assembly supported by the refill assembly support means. Thus, successful placement of a battery in the battery hold serves to both verify and maintain the correct placement of the refill assembly in the air flow path. An air-transmitting refill assembly for use with the dispensing device includes an air-transmitting substrate and a tab attached to the margin of the substrate. The tab has a brace surface facing generally away from the substrate and shaped to engage the surface of a battery being held within the battery holder of the dispensing device.

Abstract: The present invention is an occlusion device (10) adapted for implantation into a fluid flow-supporting body lumen. The occlusion device (10) comprises a flexible support structure (13) and a flexible fluid flow-occluding membrane (20) that is positioned concentric with the flexible support structure (13). The support structure (13) is formed from a plurality of interwoven filaments (16) that form an axially flexible and radially compressible structure that, in its expanded state, engages the lumen. The membrane (20) generally includes a constricted region (24) and constriction means, such as a mechanical seal (28), for closing the membrane (20) at one end. The membrane (20) is formed from a plurality of filaments (26), and in one embodiment, the membrane filaments (26) are tightly interbraided with the structure filaments (16) to form the occlusion device (10). Alternatively, the membrane (20) is separately fabricated of interwoven filaments, and is positioned either within the support structure or without the structure so as to surround the support structure.

Title: Method for treating contaminated water
Inventor: O'HANNESIN STEPHANIE FRANCES
IPC: B09C1/00
Filed: 1996-10-18
Granted: 2005-08-09
Abstract: Groundwater, or other water contaminated with chlorinated organic contaminants, is passed through a permeable body of iron particles. The particles are coated with nickel, but the coating is incomplete, in that, in patches, the iron is directly exposed. The contaminants break down under prolonged proximity to the iron, the nickel enhancing the catalytic effect. The rate of breakdown is much faster than when bare iron particles were used. When the nickel is alloyed with phosphorus, or boron, even more rapid breakdown rates are achieved.

Abstract: A local language is pre-stored in permanent memory (24). Equivalent data is transmitted in the vertical blanking interval (VBI) to television receivers (17). Each equivalent data set comprises a unique language identifier (38) and a foreign language translation (36) of, or graphical representative of, the local language pre-stored in permanent memory. The viewer selects the language to be displayed from an on screen menu with a remote controller (23). The selected equivalent data is retrieved from the VBI and stored in a RAM (18) for future display. When the microprocessor calls up the text of a command for display, the equivalent data is substituted for the local language data so the foreign language version of the command can be displayed in a seamless manner.  If no equivalent data is stored in the RAM, the local language pre-stored in permanent memory is displayed on the television screen in accordance with the normal operation of the microprocessor.

Abstract: L'invention concerne des articles de brosserie comportant un support pour les poils et un ensemble de poils constitué de poils individuels en matière plastique. Le procédé de production de ces articles de brosserie consiste à introduire les extrémités côté fixation de chaque poil individuel dans un trou d'un gabarit perforé, dont le diamètre des trous est légèrement supérieur à celui d'un poil individuel et dont le motif de perforation correspond au positionnement des poils dans un ensemble de poils ou une partie de cet ensemble. Les poils sont introduits de sorte que leurs extrémités côté fixation dépassent d'une longueur pratiquement égale du côté opposé du gabarit perforé. Les poils sont ensuite fixés dans le gabarit perforé de façon à empêcher tout déplacement axial et radial. Une couche de matériau liquide durcissable est préparée au moins sur la surface côté fixation du support de poils, et entoure les poils dont les extrémités côté fixation sont plongées dans la couche, puis cette dernière est durcie.
