Abstract
A plastic cube supports a seven-segment numeric display on each of its six facets. Within the cube, an electronic circuit including a random number generator and motion sensing switch are supported. During cube motion, the electronic circuit is operative to impress various numbers on the numeric displays. Once motion ceases, the last occurring number is displayed on all six numeric displays.
Claims11
An electronic playing die for use by a player in tumbling said electronic playing die across a playing surface, said electronic playing die comprising:
- an insulative housing defining an interior and a plurality of external facets;
- a plurality of electrically operable numeric displays, each capable of displaying a selected one of a plurality of numbers in response to a coded electrical signal, supported on at least some of said facets in said plurality of external facets;
- and
- circuit means, supported within said insulative housing interior and coupled to said plurality of numeric displays, including means responsive to motion of said electronic playing die for selecting a common number independent of die position and for causing said numeric displays to display said common number on said plurality of numeric displays following cessation of playing die motion.
1 more element
An electronic playing die comprising:
- an insulative multi-faceted housing having a number display on each facet thereof;
- and
- circuit means for causing rapid blinking of said numeric displays during playing die motion and for causing a single number selected by chance which is independent of playing die position to be simultaneously displayed on all the number displays at each cessation of playing die motion.
An electronic playing die comprising:
- a multifaceted housing defining a plurality of facets and an interior cavity;
- a motion sensing means producing an output signal indicative of playing die motion;
- a number generator producing a rapidly changing series of electrical signals corresponding to numeric digits;
- a plurality of multisegment numeric displays supported on said facets of said multifaceted housing;
- and
- a display driver coupled to said motion sensing means and said numeric number generator, causing said numeric displays to simultaneously display the number corresponding to an electrical signal produced by said number generator at interruption of said output signal of said motion sensing means said number displayed being independent of playing die position.
