Wager recognition system having ambient light sensor and related method
First Claim
1. A token sensor assembly for detecting presence of a token in variable light conditions, comprising:
- a container having side walls that define an inside perimeter and an outside perimeter between a top end and a bottom end of the container;
a translucent cover coupled to the top end of the container, the translucent cover configured to pass wavelengths of a predetermined range within a visible spectrum for transmission through the translucent cover;
a passive ambient light sensor disposed on a circuit board within the container, the passive ambient light sensor configured to;
operate in a high gain mode within the variable light conditions having a light range of 11 lumens per square meter (lux) to at least 400 lux;
generate a signal responsive to detecting an absence of light entering the container when a token is placed on the translucent cover; and
transmit the signal indicative of placement of the token on the translucent cover to a game controller; and
a plurality of light sources operably coupled with the passive ambient light sensor, the plurality of light sources configured to provide a visual indication of a wager responsive to the signal, wherein the token sensor assembly is configured to poll a condition of the passive ambient light sensor if the plurality of light sources is off and not poll the condition of the passive ambient light sensor if the plurality of light sources is on.

Abstract
A gaming table apparatus has a gaming table with a gaming table support surface. A token sensor assembly includes a container having a height and side walls that define an inside and outside perimeter of the container, and a top surface and bottom surface, a translucent cover disposed on the top surface of the side walls, a circuit board secured to the inside perimeter of the container, a plurality of lights disposed on a top side of the circuit board, and a passive ambient light sensor disposed on the top side of the circuit board. The passive ambient light sensor and the translucent cover may operate within predetermined wavelength ranges for receiving and passing light, respectively. A condition of the passive ambient light sensor may not be polled if the plurality of lights is emitting light.

14. A method of controlling a token sensor assembly, the method comprising:
-
operating a passive ambient light sensor in a high gain mode over variable ambient light conditions between 11 lux and at least 400 lux; detecting ambient light within a subset of a visible light spectrum passing through a translucent cover of the token sensor assembly indicative of absence of a token being positioned on the translucent cover for the token sensor assembly; detecting absence of the ambient light indicative of the token being positioned on the translucent cover for the token sensor assembly; transmitting a signal to at least one of a game controller or a light controller indicating whether the token is positioned on the translucent cover; generating light with a plurality of light sources from within the token sensor assembly, the generated light passing through the translucent cover and out from the token sensor assembly if a presence of a wager is detected; and ceasing to poll a condition of the passive ambient light sensor while the plurality of light sources is generating the light. - View Dependent Claims (15, 16, 17)
