Abstract

An enhancement to a typical four-function calculator. With this enhanced calculator, lottery players may generate psuedo-random integer combinations for their use in selecting numbers on which to place their bets. The enhanced calculator allows users to select the type of lottery game for which the number combinations will be generated by specifying the quantity of numbers generated and the bounds of the range within which the numbers will be generated through two key strokes of dedicated keys. The first key stroke utilizes a key designated by the particular lottery game. The second key stroke utilizes a key designated by a popular range of numbers used by the various lotteries. This invention relieves the user from having to rely on his limited supply of "magical" dates, ages, social security numbers and so forth.

Claims

1. An electronic numeric generator, comprising:

first means for calculating psuedo random integer combinations;

second means connected to said first means for allowing a user to select a quantity of integers for forming said psuedo random integer combinations;

third means connected to said first means for allowing a user to select bounds of the range of said integers for said psuedo random integer combinations;

fourth means connected to said first means for visually displaying said psuedo random integer combinations;

a display multiplexer counter;

fifth means connected to said first means for selecting a random seed for said psuedo random integer combinations from said display multiplexer counter; and

sixth means connected to said first means for choosing random integers within a range based on the probability of the occurrence of each integer, and sequencing through said range of integers in ascending order and choosing those integers which fall within a specified probability.

2. An electronic numeric generator as recited in claim 1 wherein said second and third means comprise a keyboard having dedicated keys to allow a user to select the quantity of integers generated in integer combination and the bounds of the range of generated integer combinations;

said dedicated keys being comprised of eight (8) keys placed on two (2) rows, four (4) keys per row;

one of said rows comprised of keys designated with four (4) popular lottery games;

said other row comprised of keys designated with bounds of four (4) popular ranges of lottery game numbers.

3. An electronic numeric generator as recited in claim 1 which further comprises means for displaying said integers in ascending order on said display.

4. Apparatus for numerical generation and calculation, comprising:

a keyboard having a plurality of keys thereon;

a first set of keys of said plurality of keys on said keyboard operative to select a quantity of randomly generated numbers;

a second set of keys of said plurality of keys in said keyboard operative to define a range containing all of said randomly generated numbers;

a display presenting visual indicia of said randomly generated numbers;

means connected to said first and second sets of keys for generating said quantity of randomly generated numbers within said range, generating a seed number from which said randomly generated numbers are evolved, and assuring that said quantity of randomly generated number does not include any two (2) identical numbers; and

wherein said keyboard further includes a set of keys bearing the digits 0-9 and the indicia of the four (4) basic arithmetic functions.
