Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
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.
Claim 2
Dependent Claim
135 words
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.
Claim 3
Dependent Claim
39 words
An electronic playing die as set forth in claim 1 wherein said circuit means includes blinking means responsive to motion of said electronic playing die for causing said plurality of numeric displays to blink rapidly during playing die motion.
Claim 4
Dependent Claim
47 words
An electronic playing die as set forth in claim 2 wherein said circuit means includes a number generator responsive to playing die motion for producing a rapid sequence of numbers and means for applying said rapid sequence of numbers to said numeric displays during numeric display blinking.
Claim 5
Dependent Claim
40 words
An electronic playing die as set forth in claim 3 wherein said circuit means includes means responsive to playing die motion for disabling said blinking means and number generator in the absence of playing die motion for a predetermined interval.
Claim 6
Dependent Claim
118 words
An electronic playing die as set forth in claim 1 wherein said circuit means includes: a motion switch responsive to playing die motion; a multivibrator coupled to said motion switch producing an active signal during playing die motion; an oscillator producing a clock signal; a frequency divider, coupled to said oscillator, producing frequency divided signal lower in frequency than said clock signal; a number generator producing a sequence of electrical signals representative of numeric digits; a display driver, coupled to said plurality of numeric displays and said number generator; a display blinking and blanker circuit coupled to said multivibrator, said frequency divider, and said display driver; and a display latch coupled to said display blinking and blanker circuit.
Claim 7
Dependent Claim
64 words
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.
Claim 8
Dependent Claim
64 words
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.
Claim 9
Dependent Claim
32 words
An electronic playing die as set forth in claim 6 further including means for sensing absence of playing die motion exceeding a predetermined interval and deactivating said circuit means in response thereto.
Claim 10
Dependent Claim
113 words
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.
Claim 11
Dependent Claim
113 words
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.
Claim 12
Dependent Claim
31 words
An electronic playing die as set forth in claim 8 wherein said housing is a six-faceted cube and wherein said number generator produces a rapid sequence of numbers one through six.
Claim 13
Dependent Claim
19 words
An electronic playing die as set forth in claim 9 wherein said numberic displays are light emitting diode displays.
Claim 14
Dependent Claim
18 words
An electronic playing die as set forth in claim 9 wherein said numeric displays are liquid crystal displays.
