Abstract

There is disclosed an electronic calculator capable of implementing a handicap formula for selecting and computing the probability of success of an entry in a racing contest based on past performance and earnings. The calculator can be used as an ordinary calculator or by means of a selector circuit, be placed in a handicapping mode to enable a user to compute the purse level of an entry at any one of a plurality of different tracks. The calculator is electronic and hence, performs all functions with great speed and ease.

Claims

1. A calculator of the digital type particularly adapted for indicating a rating of an entry in a racing contest by operating on the past performance of said entry as regarding past wins (W), past seconds (S) and past thirds (T) and total monies earned by said entry in said past performances, comprising:

a. a keyboard for keying in a code having a given number of digits of a predetermined length indicative of past wins (W), past seconds (S) and past thirds (T),

b. means responsive to said code for multiplying said keyed digits associated with said wins W, said seconds S and said thirds T each by a separate corresponding factor, to provide a separate product for W, S and T,

c. means responsive to said products for adding the same to provide a total sum,

d. means responsive to said total sum for dividing the same into unity to produce at an output, a class factor,

e. means responsive to said class factor for multiplying the same by said total monies earned to obtain a rating number, and

f. means for displaying said rating number.

2. The calculator according to claim 1 wherein said means for multiplying said digits include a plurality of digital multiplying circuits to multiply said W digits by a factor of X, said S digits by a factor of Y and said T digits by a factor of Z.

3. The calculator according to claim 2, wherein:

X = 0.60, y = 0.22, z = 0.12

4. the calculator according to claim 2 wherein said different preselected factors are selected according to a purse distribution at a given contest location whereby X is indicative of the percentage of the purse paid to an entry securing a win in a previous contest and Y is indicative of the percentage of the purse paid to a second place, and Z is indicative of the percentage paid to a third place.

5. The calculator according to claim 1 further including at least one additional digit for indicating past fourths (F).

6. Apparatus for indicating a rating of an entry in a racing contest by operating on the past performance of said entry as regarding past wins (W), past seconds (S) and at least one other position as thirds (T) and total monies earned by said entry in past performances, said rating provided according to predetermined factors selected according to the money distributed at a particular racing location or track in regard to the percentage of the purse (X) given for a WIN, the percentage of the purse (Y) given for a SECOND (S) and the percentage of the purse (Z) given for said other position, comprising:

a. a numerical keyboard for keying in a number indicative of said past wins (W), past seconds (S) and said other past position (T), said keyboard further having a plurality of separate keys for selecting a purse distribution as determined by said racing location,

b. a memory coupled to said keyboard and having a plurality of storage locations, each separate one associated with one of said separate keys for storing therein a predetermined number of said factors, each determined according to said purse distribution as X, Y and Z, and each location selectable by the activation of said associated key, said memory responsive upon said key selection to store therein said number indicative of said past wins W, seconds S and other position T,

c. logic means responsive to said indications (W,S and T) being stored to process the same to provide a total number for an entry according to the summation of the products of said factors and said past positions as related to XW + YS + ZT,

d. arithmetic means responsive to said total number for providing the reciprocal thereof indicative of a class factor

e. means responsive to said arithmetic means providing said class factor for multiplying said class factor by said total monies earned for providing a rating, and

f. display means coupled to said means for displaying said rating.

7. The apparatus according to claim 6, wherein:

X = 0.60, Y = 0.22, Z = 0.12.

8. The apparatus according to claim 6 wherein W,S and T can be any integer between 0 to 99.

9. The apparatus according to claim 6 wherein X is a number between 0.1 and 0.8, Y is a number between 0.05 and 0.5, Z is a number between 0.05 and 0.5.

10. The apparatus according to claim 6 wherein X, Y and Z are predetermined according to the purse distribution at a given place of contest wherein X is equal to the decimal equivalent of the percentage of said purse given to a WIN (W), Y the decimal equivalent of the percentage of the purse given to a SECOND (S) and Z the decimal equivalent of the percentage of the purse given to a THIRD (T).

11. Apparatus for indicating the rating of an entry in a racing contest at a desired racing location by operating on the past performances of said entry as regarding past wins (W), past seconds (S) and at least one other finishing position as thirds (T), comprising:

a. a memory having a plurality of selectable storage locations, each location capable of storing a set of numbers indicative of past wins (W), past seconds (S) and said at least one other finishing position (T), each location permanently storing a set of factors determined according to said desired racing location,

b. a keyboard coupled to said memory and having a first set of keys operative to select any one of said storage locations and a second set of keys operative to key in code indicative of said numbers as past wins (w), past seconds (S), and at least said one other finishing position (T),

c. logic means responsive to said selection of said memory location and said keyed code to provide at an output, a class factor manifesting an arithmetic combination of said stored factors as operating on said code, whereby said class factor is indicative of a rating for an entry, and

d. means for displaying said factor.

12. A calculator of the digital type particularly adapted to indicate a rating for any one of a plurality of entries in a racing contest at a predetermined racing location, said rating derived from past performance data as to position finished by said entry in previous contests, comprising:

a. a keyboard for keying in a predetermined number of digits indicative of a given position finished by said entry in previous contests as derived from said past performance data as (W) for past wins, (S) for past seconds and (T) for another past position,

b. memory means coupled to said keyboard for storing said predetermined digits, said memory means further having at least one storage location, indicative of said racing location, to store therein a plurality of factors associated with each of said past positions as X for wins, Y for seconds and Z for said another past position,

c. logic means responsive to said predetermined number of digits as stored to provide an output proportional to;

##EQU7## and d. display means responsive to said output for displaying the same to provide an indication of a rating for said entry.

13. The calculator according to claim 12 wherein said plurality of factors as X, Y and Z are determined according to the percentage of a purse distribution at said racing location wherein X is proportional to the percentage of said purse allocated a winner, Y is proportional to the percentage of said purse allocated to a second and Z is proportional to the percentage of said purse allocated to said another position.

14. The calculator according to claim 12 further including means for multiplying said displayed output by the total earnings of said entry as determined by said past performance data.
