  • Publication number: 20230058810
    Abstract: A gaming system and method that provides an extra award feature in a gaming environment, wherein the extra award feature provides an easier way than known methods for providing non-linear adjustments to the average expected return for the player for a play of a game without changing or reconstructing the underlying components of the game or any related game. The extra award feature provides for these non-linear adjustments to the average expected return to the player that can be based in part on wager level increases by the player. The extra award feature can include a determination of whether to provide the player a first extra award, and in certain instances, a determination of whether to provide the player a second extra award based in part on an escrow pool.

  • Publication number: 20230017168
    Abstract: A device for connecting a laboratory animal to at least one experimentation system including a body provided with a base for fastening to a bone surface of the animal and at least one element for connection to the experimentation system. The base comprises a perforated fastening structure that has a proximal face with a shape complementary to that of the bone surface and, opposite the proximal face, a distal face that delimits at least two fastening openings emerging at the proximal and distal faces. A method for fastening such a device to a laboratory animal is also disclosed.

  • Patent number: 10423017
    Abstract: Method for determining the characteristics of a system for generating at least one pattern of light, the method comprising: a) providing a desired pattern of light, b) expressing the amplitude and the phase of the output pulse of the system as a function of the input laser pulse and in function of the characteristics of the system to obtain a calculated output pulse, the input laser pulse having a duration below or equal to 1 nanosecond, c) determining at least one characteristic of the system by minimizing a distance between the calculated output pulse and the desired output laser pulse.

  • Patent number: 10191268
    Abstract: The present invention concerns a method for generating a pattern of light, this method comprising the following steps: a) emitting an input laser pulse (P1), b) deflecting the input laser pulse (P1) by a first deflector (22) to obtain a first laser pulse, c) deflecting the first laser pulse (P3) by a second deflector (24) to obtain a second laser pulse (P4), and d) focusing the pulse (P4) by an optical element characterized in that: —the first deflector (22) shapes the first laser pulse (P3) according to a first function, —the second deflector (24) shapes the second laser pulse (P4) according to a second function, and—the first function f(x) and the second function g(y) are computed and/or optimized to obtain the desired pattern of light.

  • Patent number: 9990807
    Abstract: A community gaming system including a central controller and a plurality of gaming terminals each with a graphical user interface operating. The system determines that a bonus event is triggered and which of the terminals qualify. The central controller transmits a trigger signal to each of the qualified gaming terminals in the sequence in turn, in response to which each qualified gaming terminal initiates scrolling of a bonus event graphic across its respective graphical user interface such that as the bonus event graphic scrolls across the graphical user interface of one of the qualified gaming terminals to reach an edge of that graphical user interface a next one of the qualified gaming terminals in the sequence then initiates scrolling of that bonus event graphic across its graphical user interface. The bonus event graphic appears to scroll across successive graphical user interfaces of the sequence of terminals.

  • Patent number: 9886815
    Abstract: A computer-implemented method for enhancing game components in a gaming system using various three-dimensional enhancements. The three-dimensional enhancements may involve stacks of gaming components to provide and integrate additional symbols, multi-faceted gaming components, multi-faceted gaming surfaces running multiple games in parallel, items animating to simulate real-world physics, merging components, shapes to push up or down gaming components to create stacks, and so on. Further example three-dimensional enhancements are described.

  • Patent number: 5450048
    Abstract: A removable calibrating unit comprises a body, a front panel and a part in the form of a reversible ramp. The reversible ramp comprises an end close to the front panel and an end away from the front panel. Extraction of the removable unit is achieved by means of a pin comprising an extraction lug. When the pin is subjected to rotational movement in one direction, the lug moves from the end close to the front panel to the end away from the front panel and results in extraction of the unit by applying thereon a force separating the unit from the circuit breaker.
