Bet sensors
A bet sensor for determining the value of a wager includes an at least partially transparent cover having a bet placement surface configured and oriented to support a stack of gaming tokens thereon. The bet sensor includes a mirror arrangement disposed on an opposing side of the at least partially transparent cover from the bet placement surface. The mirror arrangement is located and configured to provide a view greater than 180 degrees of a lateral side surface of the stack of gaming tokens when supported on the bet placement surface. Another bet sensor may include an at least partially transparent cover having a bet placement surface and an image sensor located substantially directly below the bet placement surface, the image sensor configured to capture a view greater than 180 degrees of a lateral side surface of the stack of gaming tokens when supported on the bet placement surface.
1. A bet sensor, comprising:
an at least partially transparent cover having a bet placement surface configured and oriented to support a stack of gaming tokens thereon; and
a mirror arrangement disposed on an opposing side of the at least partially transparent cover from the bet placement surface, the mirror arrangement located and configured to provide a view greater than 180 degrees of a lateral side surface of the stack of gaming tokens when supported on the bet placement surface.
2. The bet sensor of claim 1 , wherein the mirror arrangement comprises a first mirror facing a second mirror.
3. The bet sensor of claim 2 , wherein the first mirror includes an annular reflective surface facing inward with respect to and about a longitudinal axis of the mirror arrangement.
4. The bet sensor of claim 3 , wherein the second mirror is located concentrically within the first mirror.
5. The bet sensor of claim 4 , wherein the second mirror includes an outward-facing reflective surface extending greater than 180 degrees about the longitudinal axis of the mirror arrangement.
6. The bet sensor of claim 5 , wherein the outward-facing reflective surface of the second mirror is frustoconical in shape.
7. The bet sensor of claim 6 , wherein the second mirror comprises a structure having an aperture extending longitudinally therethrough, the second mirror and the aperture each extending coaxially with the longitudinal axis of the mirror arrangement.
8. The bet sensor of claim 7 , wherein the first mirror has at least one surface defining a second aperture about the longitudinal axis of the mirror arrangement, wherein the mirror arrangement is configured to reflect light rays from greater than 180 degrees of the lateral side surface of the stack of gaming tokens from the annular, inward-facing reflective surface of the first mirror to the outward-facing reflective surface of the second mirror and through the second aperture.
9. The bet sensor of claim 3 , wherein the annular reflective surface of the first mirror has a concave, arcuate profile in a cross-sectional plane containing the longitudinal axis of the mirror arrangement.
10. The bet sensor of claim 9 , wherein the concave, arcuate profile includes a portion of a prolate spheroid.
11. The bet sensor of claim 1 , wherein a portion of the at least partially transparent cover is adjacent a reflective structure, the reflective structure selectively configured to redirect light rays emitted from a light source associated with the bet sensor and to cause the redirected light rays to pass through the at least partially transparent cover and to locations wherein the redirected light rays would impinge on the lateral side surface of the stack of gaming tokens when supported on the bet placement surface.
12. A bet sensor, comprising:
an at least partially transparent cover having a bet placement surface configured and oriented to support a stack of gaming tokens thereon; and
an image sensor located substantially directly below the bet placement surface, the image sensor configured to capture an image greater than 180 degrees of a lateral side surface of the stack of gaming tokens when supported on the bet placement surface.
13. The bet sensor of claim 12 , wherein the image sensor comprises a complementary metal-oxide-semiconductor (CMOS) image sensor.
14. The bet sensor of claim 12 , further comprising a mirror arrangement disposed on an opposing side of the at least partially transparent cover from the bet placement surface, the mirror arrangement located and configured to reflect the image greater than 180 degrees of the lateral side surface of the stack of gaming tokens onto the image sensor.
15. The bet sensor of claim 14 , further comprising at least one optical element located between the mirror arrangement and the image sensor, wherein the at least one optical element comprises a lens.
16. The bet sensor of claim 12 , further comprising a processor in communication with the image sensor, the processor configured under control of a computer program to determine a sum value of a stack of gaming tokens supported on the bet placement surface of the at least partially transparent cover using the image.
17. The bet sensor of claim 16 , wherein the image sensor is mounted to a printed circuit board, the printed circuit board in electronic communication with the processor.
18. The bet sensor of claim 16 , further comprising a light source located and configured to illuminate at least 180 degrees of the lateral side surface of the stack of gaming tokens.
19. The bet sensor of claim 18 , wherein the light source comprises a plurality of light-emitting diodes (LEDs), and wherein the processor is configured under control of a computer program to control illumination of each LED of the plurality of LEDs.
20. The bet sensor of claim 19 , further comprising an optical element configured to transmit visible light emitted by the light source to a player responsive to a state of a game played in association with the bet sensor.
