Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
An electronic card dealer comprising an electronically operated device having a display panel for displaying a deck of six differently valued translucent playing cards; a device which continuously and automatically generates games for visual entertainment whereby a small fraction of a second after the beginning of a game, all of the cards displayed will become illuminated green, means for flashing said illuminating device unsynchronized for a period of time, means for causing any one of four selected cards to instantly turn red at random, and means for then selecting one of the remaining five cards at rAndom and causing it to remain illuminated green, the comparison of the chance selected green illuminated card with the chance selected red illuminated card determining the outcome of the game.
Claim 2
Dependent Claim
126 words
An electronic card dealer comprising an electronically operated device having a display panel for displaying a deck of six differently valued translucent playing cards; a device which continuously and automatically generates games for visual entertainment whereby a small fraction of a second after the beginning of a game, all of the cards displayed will become illuminated green, means for flashing said illuminating device unsynchronized for a period of time, means for causing any one of four selected cards to instantly turn red at random, and means for then selecting one of the remaining five cards at rAndom and causing it to remain illuminated green, the comparison of the chance selected green illuminated card with the chance selected red illuminated card determining the outcome of the game.
Claim 3
Dependent Claim
154 words
In a device as described in claim 1, having a time controlled opening and closing electronic switch composed of two diodes, said electronic switch adapted to be open when the diodes conduct and adapted to be closed when the diodes do not conduct and electronic means whereby when the electronic switch is closed during a particular instant of time the resultant green selected card will be higher in value than the resultant red selected card, and when the electronic switch is open during the same particular instant time the resultant green selected card will be lower in value than the resultant red selected card, said time controlled opening and closing of the electronic switch being such that the probability of a green result selected card being higher in value than the resultant red selected card is inversely proportional to the value of the resultant red card, the magnitude of the inverse proportionality being arbitrary.
Claim 4
Dependent Claim
79 words
A device as described in claim 1, in which the random selection of the cards that determine outcome of the game is determined by the minute noise voltages which exist inherently in electronic circuits and components, such as tubes, transistors, resistors, and capacitors as applied to binary circuits, said random selection being manifested by the electrical state which a binary circuit acquires when power is initially applied to it, the randomtivity of selection not determined by any mechanical means.
