Abstract
A record is prepared recording certain findings to provide an object record. The information of the object record is compared with stored information which comprises a function of the probability of occurrence of these certain findings in a particular class. An index of matching is established between the stored information relating to the class and the information of the object record to provide readout information.
Claims26
A data processing system comprising:
- storage means storing retrievable information in the form of data representing a quantity for each of a plurality of items, said quantities being linearly related and each of which is a measure of the probability of the presence of a respective item within a category and of the probability of the non-presence of said item in said category, the sum of the quantities for each item representing substantially one,
- means for reading out said quantities from said storage means,
- means for converting each of the quantities being read out from the storage means to a logarithmic output,
- means for receiving and adding the converted quantities to provide an output of a value indicative of the logarithm of the product of said quantities, and
- sample means for transmitting to the means for receiving and adding only selected ones of the logrithmic output which correspond respectively to those items probably present in said category and to other items probably not present in said category.

A data processing system comprising:
- storage means storing retrievable information representing a quantity related to the probability of the presence of each of a plurality of items within a category and the probability of the non-presence of each of said items in said category, the sum of quantities for each item representing substantially one,
- means for reading out said quantities from said storage means,
- means for converting the quantities being read out from the storage means to a logarithmic output,
- means representing a sample in which at least some of the items are present for inhibiting the read-out from predetermined items not present in said sample and passing the read-out from the remaining items, and
- means for receiving and adding all of the converted quantities corresponding to the remaining items, wherein the storage means is surface means on which the information is carried in the form of radiation transmitting areas having radiation transmitting properties corresponding to the respective quantity and the means for reading out comprises means for producing radiations to illuminate said areas, and
- the means for converting comprises a radiation transmitting area for logarithmically modifying the amount of radiation passing through each of said areas of the storage means.

A data processing system comprising,
- storage means storing retrievable information in the form of data representing a quantity for each of a plurality of items, each of the quantities being the logrithm of a numerical value representing the probability of the presence of a respective item within a category and the probability of the absence of each such item from said category, the sum of such numbers for each item representing substantially one,
- means for receiving and adding logarithmic quantities to provide an output of a value indicative of the logarithm of the product numbers,
- and sample means for reading out and transmitting to the means for receiving and adding only selected ones of the logarithmic quantities which correspond respectively to those items probably present in said category and to other items probably not present in said category.
A data processing system for processing recorded information comprising:
- class card means having recorded thereon the probability of occurrence of certain findings in a class which comprises openings in alignment with each finding representing the total probability of occurrence thereof;
- logarithmic modification card means having recorded thereon openings in correspondence with said class card openings which modify radiations which pass through each opening to functional values of probabilities'
- object card means having areas in correspondence with said class card and function modification card openings which are adapted to be rendered lucent to said radiations;
- means for aligning said card means,
- means for producing radiant energy and transmitting said energy through said openings, the amount of energy being transmitted through aid aligned openings depending on the transmittance of each of the aligned openings;
- and
- sensing means for sensing the amount of energy being transmitted through the aligned openings.

A data processing system comprising:
- storage means storing retrievable information representing a plurality of quantities, each of which is a measure of the probability of the presence of an item within a category and of the probability of the non-presence of a respective item in said category, the sum of the quantities for each item representing substantially one,
- means for reading out said quantities from said storage means,
- means for converting each of the quantities being read out from the storage means to a logarithmic output,
- means representing a sample in which at least some of the items are present for passing only those quantities from the output corresponding to the items present in the sample and those quantities from the output corresponding to those items not present in said sample, and
- means for receiving and adding all of the converted quantities thus passed to provide a single output of a value indicative of the logarithm of the product of said quantities, wherein the storage means is surface means on which the information is carried in the form of radiation transmitting areas having radiation transmitting properties corresponding to the respective quantities and the means for reading out comprises means for producing radiations to illuminate said areas wherein the means for converting comprises a radiation transmitting area for logarithmically modifying the amount of radiation passing through each of said areas of the storage means.
