Abstract
Abstract A system of the so-called "operator-unassisted" type, for processing articles selected for purchase and bearing an identification code, includes a code reader generating output signals indicative of the article identification codes, a sensor generating output signals indicative of measurable characteristics of the articles, a memory for storage, for each of the articles, of a signal indicative of the measurable characteristic thereof correlated with the article identification code, an article rejector for rejecting the selection of an article for purchase on failure of correspondence of the sensor output signal and the corresponding stored measurable characteristic signal and a control unit operable selectively on such rejection of the article purchase selection for substituting the output signal generated by the sensor for the stored measurable characteristic signal. The control unit effectively introduces an "override capacity" to heretofore known systems.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
A system for processing articles selected for purchase and bearing an identification code, comprising: (a) code reader means for generating output signals indicative of said article identification codes; (b) sensing means for generating output signals indicative of measurable characteristics of said articles; (c) storage means for storage, for each type of article, a signal indicative of a standard or predetermined characteristic thereof correlated with the article identification code; (d) article rejection means for rejecting the selection of an article for purchase on failure of correspondence of one of said sensing means output signals and the corresponding stored characteristic signal; and (e) control means operable selectively on such rejection of said article purchase selection for substituting the one output signal generated by said sensing means for the stored characteristic signal.
Claim 2
Independent Claim
129 words
A system for processing articles selected for purchase and bearing an identification code, comprising: (a) code reader means for generating output signals indicative of said article identification codes; (b) sensing means for generating output signals indicative of measurable characteristics of said articles; (c) storage means for storage, for each type of article, a signal indicative of a standard or predetermined characteristic thereof correlated with the article identification code; (d) article rejection means for rejecting the selection of an article for purchase on failure of correspondence of one of said sensing means output signals and the corresponding stored characteristic signal; and (e) control means operable selectively on such rejection of said article purchase selection for substituting the one output signal generated by said sensing means for the stored characteristic signal.
Claim 3
Dependent Claim
20 words
The invention claimed in claim 1 wherein said sensing means generates said output signals thereof as indicative of article size.
Claim 4
Dependent Claim
20 words
The invention claimed in claim 1 wherein said sensing means generates said output signals thereof as indicative of article weight.
Claim 5
Independent Claim
280 words
A system for processing articles selected for purchase and bearing an identification code, comprising: (a) code reader means for generating output signals indicative of said article identification codes; (b) sensing means for generating output signals indicative of measurable characteristics of said articles; (c) storage means for storage, for each type of article, a signal indicative of a standard or predetermined characteristic thereof correlated with the article identification code; (d) processor means for receiving said code reader means output signals and said sensing means output signals and connected to said storage means, said processor means being responsive to receipt of each said code reader means output signal to fetch from said storage means the stored signal indicative of the characteristic correlated with the article identification code indicated in said code reader means output signal; (e) comparator means for receiving one of said sensing means output signals and one of said stored signals fetched by said processor means, for comparing the indications therein of article characteristics and for providing output signals indicative of the result of such comparison; (f) rejection means for receiving said output signals of said comparator means for rejecting the selection of said article for purchase where said comparison result is negative and providing an output signal indicative of said rejection; and (g) override means operative selectively on such rejection of article purchase selection for effecting substitution of the output signal generated by said sensing means for the stored characteristic signal, said processor means being further responsive to the receipt of said rejection means output rejection-indicative signal to enable operation of said override means and, upon operation thereof, to convey said sensing means output signal to said storage means.
Claim 6
Independent Claim
280 words
A system for processing articles selected for purchase and bearing an identification code, comprising: (a) code reader means for generating output signals indicative of said article identification codes; (b) sensing means for generating output signals indicative of measurable characteristics of said articles; (c) storage means for storage, for each type of article, a signal indicative of a standard or predetermined characteristic thereof correlated with the article identification code; (d) processor means for receiving said code reader means output signals and said sensing means output signals and connected to said storage means, said processor means being responsive to receipt of each said code reader means output signal to fetch from said storage means the stored signal indicative of the characteristic correlated with the article identification code indicated in said code reader means output signal; (e) comparator means for receiving one of said sensing means output signals and one of said stored signals fetched by said processor means, for comparing the indications therein of article characteristics and for providing output signals indicative of the result of such comparison; (f) rejection means for receiving said output signals of said comparator means for rejecting the selection of said article for purchase where said comparison result is negative and providing an output signal indicative of said rejection; and (g) override means operative selectively on such rejection of article purchase selection for effecting substitution of the output signal generated by said sensing means for the stored characteristic signal, said processor means being further responsive to the receipt of said rejection means output rejection-indicative signal to enable operation of said override means and, upon operation thereof, to convey said sensing means output signal to said storage means.
Claim 7
Dependent Claim
20 words
The invention claimed in claim 4 wherein said sensing means generates said output signals thereof as indicative of article size.
Claim 8
Dependent Claim
20 words
The invention claimed in claim 4 wherein said sensing means generates said output signals thereof as indicative of article weight.
