Abstract: A disclosed gaming machine presents pachinko games to a player playing the gaming machine. In some embodiments, a player may initiate a new pachinko game on the gaming machine while the outcome of a previous pachinko game is being presented to the player. The wagers on each game may be different. Also, a player may input parameters into the gaming machine that affect the game outcome presentation. For a number of different games, two or more game outcomes may be presented simultaneously to the player on the gaming machine. However, the game outcomes determined by the gaming machine are independent of one another and do not depend on the game outcome presentation. Normally, the game outcomes are determined using a random number generator and a pay table stored in a memory on the gaming machine.

Title: Smart bathroom fixtures and systems
Inventor: MANN STEVE
IPC: E03D9/00
Filed: 2001-08-29
Abstract: Image sensors, processors, and control systems facilitate automatic sensor operated bathroom fixtures, systems for controlling bathroom fixtures, and methods of bath-room fixture design, control, and management, as well as the control and manage-ment of hygiene and water resources. The networked plumbing systems also help facility managers and law enforcement personnel monitor the operation of various bathrooms in a facility or at remote facilities. Image sensors are used for control-ling several showers, faucets, urinals, or water closets in large bathroom complexes. Image based intelligent bathroom fixtures and systems help enhance the privacy of users by ensuring that law abiding users need not be disturbed by police foot patrols into the restroom areas, or by security guards entering simply to make inspections. An aquionics bathroom control system of the invention maintains the cleanliness, safety, security, and privacy of the occupants in a smart bathroom environment. Ad-ditionally, in some embodiments, a bathroom facility of the invention may be used for mass decontamination during times of emergency for processing victims of a nu-clear, biological, or chemical incident. Once ubiquitously installed for routine control of fixtures, the apparatus facilitates a secondary usage such as monitoring by triage staff, medical personnel, decontamination officers, or law enforcement officers during times of terrorist consequence management.

Patent CA-2363465-A1 (CA)
Title: Digital file management and imaging system and method including secure file marking
Inventor: BORROWMAN COLIN D
IPC: H04L9/32
Filed: 2000-02-24
Abstract: A digital file management and imaging system records additional independent data with each stored image (200) including a true date gleaned from a secur e clock (202) not settable by a user, a number derived from a cyclic redundanc y code (CRC) algorithm for the image data (210) and the true date (212). This additional data is recorded within each digital file as soon as possible aft er the file is acquired. If the file is altered in any way after the recording of the additional data, recalculation of the image CRC on the altered file will  not match the original image CRC recorded within it. Thus, the fact that it has been altered can be detected. Likewise, if the true date is altered in a ny way, recalculation of the date CRC will similarly reveal this fact.

Title: Stent having a multiplicity of undulating longitudinals
Inventor: FISCHELL ROBERT E
IPC: A61F2/82
Filed: 1995-02-20
Abstract: The present invention provides for an expandable stent for use in an artery or other vessel of a human body. The stent structure maintains the patency of the vessel within which the stent is expanded radially outward. One embodiment of the present invention is a stent having a multiplicity of frames joined together by at least two undulating longitudinal structures which can readily change their length in the longitudinal direction so as to provide increased longitudinal flexibility for the stent for easy passage through and placement within a curved vessel such as a coronary artery. The stent is an embodiment of the present invention having frames joined with longitudinal structures and formed from a single, thin- walled piece of metal by laser cutting or chemical etching. Because the stent is fabricated from a single piece of metal, it provides a multiplicity of closed perimeter cells that are formed as a continuous metal structure.

Title: Method and system for forming strings of pocketed coil springs
Inventor: WELLS THOMAS J
IPC: B68G9/00
Filed: 2000-03-31
Abstract: A string (12) of pocketed coil springs (14) is formed by inserting compressed springs between upper and lower plies of a folded, preferably thermally weldable fabric (16). The springs are maintained in a compressed configuration while a longitudinal seam (54) joins the free edges of the thermally welded fabric (16) together. Subsequently, the compressed springs (14) are allowed to relax into an expanded configuration after which a transverse seam (80) is formed in the fabric (16) between the adjacent springs (14) thereby encapsulating each spring (14) within a fabric pocket (86). The string (12) of pocketed coil springs (14) is advantageously formed without the need for reorienting the springs (14) after being inserted between the plies (24, 26) of the fabric (16) and thereby avoiding the disadvantages and complications associated with turning or reorienting the pocketed coil spring (14).

Abstract: An intraocular lens (38) having focusing capabilities permitting focusing movement of the lens (38) in response to normal ciliary muscle movement incident to changes in the distance between the eye and an object under observation is provided. The lens (38) is designed for surgical implantation  within the capsule (22) of an eye (10) and includes an optic (40) and a resilient body (46) which cooperate to form a discoid shaped lens (38) that generally conforms to the shape of the natural capsule (22). When distant objects are viewed, the ciliary body (32) is retracted and the capsule (22) flattens, thus causing the lens (38) to likewise flatten, moving the optic (40) posteriorly, closer to the fovea (26). When viewing near objects, the ciliary body (32) contracts, causing the capsule (22) and thus the lens (38)  to expand to their original shape, shifting the optic (40) anteriorly, away from the fovea (26). The inventive lens (38) is preferably a unitarily forme d, seamless body preferably comprising a flexible material which has elastic memory. Suitable materials comprise acrylates and silicone blends.

Abstract: L'invention concerne un système d'analyse des données relatives à un champ de pétrole basé sur un modèle logiciel à quatre niveaux comprenant un "modèle des terres partagées" et une fédération de "services répertoire". Le premier niveau est une interface utilisateur graphique universelle qui peut tourner sur n'importe quel ordinateur (12) bon marché ou sur une station (14) de travail coûteuse équipée d'un "navigateur Web". Le deuxième niveau est un serveur applicatif (18) qui est couplé aux utilisateurs via le Web et qui offre des applications logicielles géoscientifiques. Le troisième niveau est un système (20) de modélisation géométrique au niveau duquel les données géométriques sont stockées et traitées. Le troisième niveau est la réalisation du "modèle des terres partagées". Le quatrième niveau est un système (22) de gestion de base de données où sont stockées les données non géométriques. Selon l'invention, chacun de ces niveaux peut comporter (et de préférence, comporte) plusieurs instances. La communication des données entre les différents niveaux s'effectue par un échange de données XML. Selon le mode de réalisation préféré de la présente invention, les applications dans le domaine des sciences de la terre offertes par le deuxième niveau sont écrites sous la forme de servlets JAVA et ces applications peuvent communiquer les unes avec les autres sans intervention humaine grâce à l'enregistrement des demandes par les "services répertoire". Les applications portant sur certains types de données "écoutent" les "événements de données" enregistrés par les services répertoire. Le coût d'utilisation d'une application peut être basé sur une opération de facturation temps-location réalisée automatiquement via les services répertoire.
