Definitions

  • the present invention relates to improvement in the structure of roulette wheels and more specifically to a roulette wheel equipped with an electronic control system.
  • Roulette is a game which is very common all over the world. In order to monitor the progress of the game and ensure the correctness thereof, electronic control systems have been developed over time, these being intended to detect automatically the position of the ball on the moving roulette wheel.
  • These systems are based on detector devices adapted to receive the reflections of a controlled light beam which are produced by the outer numbered ring and the inner ring provided with pockets able to receive the ball, forming part of the roulette wheel, and by the ball itself.
  • the reflections are analysed in order to determine the instantaneous angular position of the wheel and the position of the ball with respect thereto.
  • EP 0 757 582 describes a method and a system for detecting the position of the ball on a roulette wheel based on the use of LED light sources adapted to emit non-coherent light in the visible range at one or more specific wavelengths which are predetermined depending on the relative chrominance parameter for the ball and the rotating wheel, with a view to maximizing the colour contrast between the ball and background.
  • WO 01/19470 discloses a roulette wheel of the type of the present invention.
  • the maximum contrast can be obtained with blue or yellow illuminating light, while detection of the angular position of the wheel can be obtained by illuminating the numbered ring (with red, black and green compartments) using red-light emitting sources.
  • All the light emitters and detectors are incorporated in a single device adapted to be installed on the edge of the roulette rim and having three light sources, two of which are directed towards spaced positions on the numbered ring and the remaining one of which is directed towards the ring provided with pockets for receiving the ball.
  • the object of the present invention is to provide a roulette wheel equipped with an improved electronic system adapted to analyse the progress of the game in a rapid and efficient manner also in the case of non-traditional roulette wheels, and ensure the correctness of the game.
  • this object is achieved by means of a roulette wheel having the characteristic features described in Claim 1.
  • Reference numeral 10 denotes generally a roulette wheel structure comprising a fixed rim 12 which is bounded by an upper ring 13 and with, arranged inside it, a wheel 14 having a first outer ring 20 on which numbered compartments are shown and a second, concentric, inner ring 22 with pockets corresponding to the numbered compartments of the first ring and adapted to receive and retain a ball during the course of the game.
  • the numbered compartments have a background which is alternately coloured red and black, except for the compartment representing the number "0" which has a green coloured background.
  • the numbered compartments may also have a bronze or silver coloured background.
  • Optical sensor devices 24 forming part of a first group, visible in Figure 2a are arranged in the roulette wheel structure underneath the wheel and include LED transmitters and corresponding receivers which are adapted to detect the position of the roulette wheel by means of the detection of printed notches on a marker disc 25 fixed thereto (shown in Figure 2b ).
  • sensors 24a, 24b which are arranged radially aligned, the outer sensor 24a being designed to detect a plurality of black notches 26 alternating with a corresponding plurality of white spaces 28 on the disc mounted underneath the wheel, and the inner sensor 24b being designed to detect a single additional marker notch 30 situated opposite the "0" compartment of the wheel.
  • the outer sensor 24a allows to detect the position of the wheel as fractions of a revolution corresponding to the subdivision of the numbers, while the inner sensor 24b, owing to the single notch 30 positioned at the "0", allows to detect the absolute position of the wheel 14.
  • the sensors are of the digital optical type, based on an LED transmitter and a corresponding receiver.
  • Reference numeral 32 denotes optical sensor devices forming part of a second group, arranged along the upper ring 13 which acts as a rolling track for the ball, and including laser transmitters and associated receivers which are oriented towards the circumference of rotation of the ball at rest 22 and adapted to detect the ball during play.
  • the optical sensors 32 are two or more in number, preferably three in number, and are arranged at angular intervals which are typically, but not necessarily equivalent to 12/37ths, 12/37ths and 13/37ths of a revolution in single "0" roulette wheels and 13/38ths, 12/38ths and 13/38ths of a revolution in double "0" roulette wheels.
  • the sensors 32 are coherent-light digital optical sensors based on a pulsed semiconductor laser transmitter.
  • Both sensors 24, 32 operate by means of detection of a variation in luminance in the direction of observation, due to the alternating succession of black notches 26 and white spaces 28, or the succession of the reflecting surface of the ball receiving pockets (regarded as a background irrespective of their colour) and the reflecting surface of the ball itself. They have a high degree of precision, of the order of 1 mm at a distance of 300 mm, also in the case where the ball is distant from the light beam source.
  • the first and second sensors 24, 30 are linked to respective control panels 35, 36 which are connected to a data collection and processing unit 40 designed for the synchronous acquisition and analysis of the position signals, of the wheel and ball respectively, during the various stages of evolution of the game.
  • the beams of light reflected by the objects to be detected are received by the sensors via a semi-reflective mirror arranged inside the sensor and are amplified and analysed by the unit 40.
  • the levelling system 50 is connected to the data collection and processing unit 40 so as to signal in real time any anomaly detected, anomaly being understood as meaning the deviation from the predetermined position.
  • An internal accelerometer is also connected to the unit 40 and is adapted to detect accelerations of the roulette wheel structure in the two or three spatial directions with respect to the original rest condition, for example owing to sudden impacts.
  • the measuring precision is about 1mg over a maximum scale of 2g, corresponding to +/-1.5 mm/m of inclination with respect to the equipotential surface of the gravitational field for a dual-axis (planar) sensor and about 2mg over a maximum scale of 3g per axis, corresponding to +/-2.0 mm/m of inclination for a three-axis sensor.
  • a dual-axis accelerometer is adapted to detect raising of the roulette wheel structure on one side (and consequent loss of the original position) or a lateral impact.
  • a three-axis accelerometer allows to determine also the acceleration or displacement along the vertical axis. It should be noted that in most cases a dual-axis accelerometer may be sufficient since it is very difficult to manage to raise a roulette wheel structure without inclining it in a manner detectable by the instrument owing to its sensitive nature.
  • the unit 40 is designed to store the instant in time when an anomaly occurs, whether it be detected by the levelling system or the accelerometer, its magnitude and duration.
  • a temperature sensor (not shown) associated with the roulette wheel structure and connected to the unit 40, for detecting the temperature of the roulette wheel in order to monitor possible thermal deformations.
  • a magnetic field sensor such as a compass, also connected to the unit 40 and adapted to determine the orientation of the roulette wheel structure with respect to the earth's magnetic field and detect any variation in the magnetic field close thereto.
  • the data collection and processing unit 40 is able to communicate, in a network having similar units associated with other roulette wheel structures of different tables, with a central processing system 70 adapted to execute a computer program or set of computer programs designed to supply the collected data to the surveillance personnel, for example by means of a simple and immediate graphics interface, and store the progress of the game conditions and any alarm situations requiring intervention of the personnel.
  • a geographical positioning system similar to a GPS satellite positioning system, is incorporated in the roulette wheel structure, in order to monitor any displacement of the structure, for example transportation of the structure from a warehouse to a games room, or transfer between different rooms.
  • the positioning system is adapted to be connected to the data collection and processing unit 40 so as to signal in real time any displacement and store the temporal data relating to the displacements which occur over time.
  • the roulette wheel is rotated in the desired direction and then the ball is thrown in the direction opposite to that of rotation of the wheel.
  • the wheel In order for the game to be valid, the wheel must rotate at a speed greater than a predetermined threshold speed which can be personalized and, similarly, the ball must be thrown so as to initiate its own rotation within the wheel at a speed which is greater than a predetermined threshold speed which can also be personalized on the basis of the regulations existing at the place of installation.
  • the control system depending on the data supplied by the sensors for detecting the kinematic data of the wheel and the ball, identifies the following stages in the game essentially as follows:
  • the direction of rotation of the wheel is detected by the sensors 24 of the first group and acquired once only with each rotation of the wheel and it is therefore necessary to wait at the most for one complete rotation in order to define the direction of rotation of the wheel.
  • the direction of rotation of the ball is instead detected by means of the sensors 32 of the second group and determined after the passing movement of the ball has been detected by at least two sensors and, therefore, in the example of embodiment described, after about 2/3rds of a revolution, namely about 240 degrees.
  • the signal of the outer sensor 24a of the first group is sent to a digital counter of the control unit 40 which is able to increment stored data, indicating the physical position of the wheel, every two notches (internally the number of pulses is divided by 2).
  • This signal is also used, by means of a dedicated input of the unit, to calculate the speed of rotation of the wheel, measuring the time which lapses between the passing movement of two notches in front of the sensor.
  • the signal of the inner sensor 24b of the first group is used to synchronize the counter of the unit 40 with the "0" compartment of the wheel.
  • the signals of the sensors of the second group 32 are sent to three separate inputs of the unit 40.
  • the angular position of the wheel is stored and this is converted into the number of the compartment of the wheel in which the ball is situated, on the basis of the predefined succession of the numbers on the ring.
  • the three signals are sent to an adder circuit, the output of which is used to calculate the speed of rotation of the ball, calculating the time which has lapsed when passing from one sensor to the adjacent sensor.
  • the data processed by the unit 40 is supplied via a serial output to an external processor for display and statistical processing.
  • a computer program or set of computer programs adapted to be executed by the central processing system manages the data processed by each control unit 40 of a roulette table, analysing the progress of the game and signalling to the competent personnel any anomalies which may adversely affect the correctness thereof
