Title: Linked gaming machines having a common feature controller
Inventor: PIECHOWIAK ROBERT J
IPC: G07F17/32
Filed: 1995-02-21
Granted: 2006-08-01
Abstract: The preferred embodiment of the present invention operates on a system of interconnected gaming machines. In a normal operation mode, the individual machines provide awards to individual players based on the generation of symbol combinations in a first group of symbol combinations. The linked gaming machines are polled by a feature controller to determine whether symbol combinations in a second group of combinations are generated. These symbol combinations in the second group of combinations are accumulated until a level is reached such that a bonus award will be given to the next player whose machine generates a symbol combination within said second group of symbol combinations. The first machine to generate a winning symbol combination within said second group of symbol combinations is given a bonus award. The feature is then reset. The status of the feature is displayed for all players of the linked gaming machines.

Abstract: L'invention a pour objet une méthode de recherche de gisements pétroliers comprenant la réalisation d'un modèle déterministe numérique de type diffusif permettant la simulation en 2D ou 3D du remplissage des bassins sédimentaires par des sédiments siliclastiques et carbonatés. A partir de données connues sur l'architecture d'un bassin et de données de mesures choisies parmi des diagraphies de puits et campagnes sismiques. On constitue un ensemble de données d'entrée portant sur l'espace disponible créé par subsidence et eustatisme, sur l'apport et la production de sédiments fluviatiles ou marins, et sur des paramètres physiques de transport tels que des coefficients de diffusion des différentes lithologies. Cet ensemble de données est appliqué à un modèle numérique. Les résultats que l'on peut en déduire sur la géométrie et les lithologies des unités sédimentaires, sont confrontés avec les données de mesure et, de proche en proche, par inversion, on affine les données d'entrée. Le modèle ainsi construit permet de restituer par exemple le partitionnement volumétrique, la distorsion des unités génétiques ou les géométries sédimentaires observées.
Patent CA-2204819-C (CA)

IPC: B41J17/12
Filed: 1997-05-08
Granted: 2001-10-23
Abstract: A thermal printer for printing on a continuous print medium by ink transfer from a thermal print ribbon has a print head which is pivotally mounted and which is driven in an oscillatory nodding motion by means of a stepper motor so as repeatedly to bring a linear array of energisable printing elements to bear against a platen roller. Both the element array and the platen extend transversely to respective paths of travel of the print medium and the ribbon. The print medium is fed through the printer from an inlet region, between the platen and print head, and thence to an outlet region. The instantaneous rate of travel of the print medium past the print head is substantially the same as the rate of feed of print medium to the printer. Typically this rate is of the order of 250 to 400 mm per second. The ribbon also travels between the print head and the platen, overlying the print medium and is driven in such a manner that it travels at the same rate as the print medium during each printing operation up to a speed equivalent to the maximum printing speed of the print head. This is achieved by driving the ribbon with a motor the speed of which is controlled according to the sensed speed of travel of the print medium, e.g. by coupling the motor to processing circuitry which takes an input signal from a shaft encoder associated with the platen roller. These methods of driving the ribbon have the advantage that the ribbon speed can be varied to take account of different print medium speeds, e.g. due to the requirements of differing packaging processes, and also in response to transient variations in print medium speed during each printing operation. To restore the aspect ratio of characters when the print medium is travelling faster than the speed equivalent to the maximum speed of the print head, lines of dots are skipped.

Title: Rcc-type switching power supply
Inventor: SHIMAMURA TAKASHI
IPC: H02M3/335
Filed: 1997-04-10
Granted: 2000-10-24
Abstract: An RCC-type switching power supply has a main switch means 9 which is repeatedly rendered conductive and cut off to cause a switching current to flow through a primary winding 31 for transferring energy from a primary side to a secondary side due to flyback operation. A snubber circuit 5a - 5c has a snubber capacitor 7 and an auxiliary switch means 3 which are connected in series with each other and parallel to primary winding 31. When the auxiliary switch means 3 is rendered conductive by an auxiliary winding 4 when the main switch means 9 is cut off, the auxiliary charge the snubber capacitor 7 with energy stored in a leakage inductance of the primary winding 31, and then effects first-quadrant operation to discharge the snubber capacitor 7 to cause a current to flow through the primary winding 31. The current transfers the energy to the secondary winding 32 or charges a smoothing capacitor 21 on the primary side to transfer the energy to a rectifying and smoothing means 18 on the primary side. Since no surge voltage is applied to the main switch means 9 and the energy stored in the leakage inductance is not wasted, the RCC-type switching power supply 2a - 2c produces low noise and is highly efficient.

Abstract: A system (43) and method for improving handoff performance of a cellular telecommunications network (20) having a serving exchange and a serving cell (C) in which a mobile station is engaged in a call.      The system adapts a first timeout period during which signal strength measurements are collected from a plurality of cells (A, B, D, G and H) that neighbor the serving cell. A variable timing mechanism (45) measures time periods starting when a handoff measurement request is generated. The system then sets the variable timing mechanism (45) to measure a specified time period for each of the plurality of cells, collects the signal strength measurements during the specified time period, and processes the signal strength measurements when the specified time period expires. The system (43) also adapts a second timeout period during which a handoff request from the mobile station is queued while awaiting an available voice channel in a target cell for handoff. The system (43) measures a default value for the second timeout period, changes the default second timeout period to an adapted second timeout period for which there is a maximum probability of handing off a call associated with the handoff request, and determines whether the handoff request should be queued for the default second timeout period or the adapted second timeout period.

Abstract: A roller is provided for a pressure treatment of a web of paper, textile, plastic film, or the like, and is composed of a rotary hollow cylinder which can be distinctly deformed under the effect of line forces in the roll nip. The roller includes a non-rotary cross-head which penetrates the rotary hollow cylinder over its length. On the side of the roll nip, hydraulic supporting elements are provided which can be pressed against the inside circumference of the hollow cylinder in the manner of piston/cylinder units. These supporting elements have a length of not more than 20 cm in the longitudinal direction of the cross-head, and are closely arranged next to one another in the longitudinal direction of the cross-head. The supporting elements can be driven independently of one another at least in several groups. A sealing strip is also provided which continues in one piece over several supporting elements (which follow one another in the longitudinal direction of the cross-head). The supporting elements rest against the sealing strip from below, and the sealing strip acts against the inside circumference of the hollow cylinder, at the top. At the top, the sealing strip has a bearing pocket (which has an all-around edge and is open towards the inside circumference of the hollow cylinder)above each supporting element. The edges at the adjacent sides of bearing pockets which follow one another in the longitudinal direction of the roller are formed by a transverse edge common to both bearing pockets.
