Abstract

Abstract A computer weigher system employs a continuously operating digital computer which multiplies unit price information supplied via a manual keyboard times the weight information supplied via a weigher which incorporates a digitizer for converting the weight information to digital form. From the moment that the article is first placed on the weigher scale until the weigher platform comes to balance, successive intermediate weight measurements are made as the platform moves to balance, and the computer arithmetic unit continuously operates to develop the total price for each such weight measurement. A display device continuously displays the unit price together with the weight measurement as it varies from the zero ;measurement to the final balance measurement, as well as the total price at each measured weight. An operator can determine when the weigher platform has come to balance from the displayed weight, and when the later is unchanged, the operator presses a print button which initiates the operation of a printer to print out the weight and total price as well as the input unit price.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 94 words
A computer weigher system comprising: a weigher including means for producing digital representations of the weight of an article being weighed before and after the weigher comes to balance, manual keyboard means for generating a digital representation of unit price of the article; means for repeatedly multiplying said weight representations by said unit price representations to obtain total price representations; and means for repeatedly displaying said weight representations and said total price representations, whereby the data display appears to change continually before the weigher comes to balance and appears to remain unchanged after balance.
Claim 2
Dependent Claim 94 words
A computer weigher system comprising: a weigher including means for producing digital representations of the weight of an article being weighed before and after the weigher comes to balance, manual keyboard means for generating a digital representation of unit price of the article; means for repeatedly multiplying said weight representations by said unit price representations to obtain total price representations; and means for repeatedly displaying said weight representations and said total price representations, whereby the data display appears to change continually before the weigher comes to balance and appears to remain unchanged after balance.
Claim 3
Dependent Claim 55 words
A computer weigher system as recited in claim 1 and further comprising: means for printing a record of said weight and total price representations, including a manually operated print-controlling switch for actuating the printing of the record, whereby an operator can initiate the printing of said record when the displayed representations appear to remain unchanged.
Claim 4
Dependent Claim 37 words
A computer weigher system as recited in claim 1 wherein said multiplying and displaying means each operate repeatedly at least about 30 times per second whereby the image of the display is effectively continuous for the operator.
Claim 5
Dependent Claim 43 words
A computer weigher system as recited in claim 1 and further comprising: selectively operable means for sorting digital tare weight representations; and wherein said multiplying means includes means for repeatedly subtracting said tare representations from said weight representations prior to each repeated multiplication.
Claim 6
Dependent Claim 49 words
A computer weigher system comprising the process steps of: repeatedly generating electrical representations of the weight of an article while it is being weighted; repeatedly multiplying said weight representations by a certain unit price factor to obtain total price representations; and repeatedly displaying said weight and total price representations.
Claim 7
Dependent Claim 49 words
A computer weigher system comprising the process steps of: repeatedly generating electrical representations of the weight of an article while it is being weighted; repeatedly multiplying said weight representations by a certain unit price factor to obtain total price representations; and repeatedly displaying said weight and total price representations.
