Abstract
Abstract An improved control for an electronic computing scale which computes, for example, the value of an article based upon a predetermined price per unit weight for the article. The weight of the article is multiplied times the predetermined price to obtain the article value which is displayed on a visual readout device. The weight used in computing the value is stored in a memory. The weight of the article is periodically measured and compared with the stored weight. A new value is computed only when a measured weight differs from the weight stored in the memory. The memory is cleared if the predetermined price is changed or the article is removed from the scale. In addition to the value, the predetermined price and the weight stored in the memory are displayed on visual readout devices.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
98 words
An improved computing scale which displays desired data calculated from a predetermined weight factor for an article and a measured weight of such article comprising, in combination, means for periodically measuring the weight of the article, computing means for calculating the desired data from such measured weight and the weight factor, memory means for storing such calculated daTa until new data is calculated, means for displaying the data stored in said data memory means, and means for inhibiting said computing means from calculating new data when a measured weight is the same as the immediately preceding measured weight.
Claim 2
Dependent Claim
98 words
An improved computing scale which displays desired data calculated from a predetermined weight factor for an article and a measured weight of such article comprising, in combination, means for periodically measuring the weight of the article, computing means for calculating the desired data from such measured weight and the weight factor, memory means for storing such calculated daTa until new data is calculated, means for displaying the data stored in said data memory means, and means for inhibiting said computing means from calculating new data when a measured weight is the same as the immediately preceding measured weight.
Claim 3
Dependent Claim
85 words
An improved computing scale, as set forth in claim 1, wherein said inhibiting means includes memory means for storing the measured weight from which the stored data was calculated, means for comparing each periodic measured weight with such weight stored in said weight memory means, means for causing said computing means to calculate new data from any periodic measured weight which differs from such stored weight, and means for storing in said weight memory means any periodic measured weight which differs from such stored weight.
Claim 4
Dependent Claim
24 words
An improved computing scale, as set forth in claim 2, and including means for displaying the article weight stored in said weight memory means.
Claim 5
Dependent Claim
42 words
An improved computing scale, as set forth in claim 3, wherein said weight measuring means has a maximum weight capacity, and including means for blanking at least a portion of said weight displaying means when such maximum weight capacity has been exceeded.
Claim 6
Dependent Claim
37 words
An improved computing scale, as set forth in claim 2, wherein said weight measuring means has a maximum weight capacity, and including means for clearing said data memory means when such maximum weight capacity has been exceeded.
Claim 7
Dependent Claim
29 words
An improved computing scale, as set forth in claim 2, and including means for clearing said weight memory means when the article is removed from said weight measuring means.
Claim 8
Dependent Claim
36 words
An improved computing scale, as set forth in claim 2, and including means for clearing said weight memory means in response to a change in successive weight measurement from a negative value to a positive value.
Claim 9
Dependent Claim
50 words
An improved computing scale, as set forth in claim 2, and including memory means for storing the predetermined weight factor, means for changing the stored weight factor, and means responsive to a change in the stored weight factor for clearing both said weight memory means and said data memory means.
Claim 10
Dependent Claim
39 words
An improved computing scale, as set forth in claim 2, wherein said data memory means has a maximum memory capacity, and including means for clearing said data memory means in response to calculated data exceeding such maximum memory capacity.
Claim 11
Independent Claim
91 words
A method for calculating and displaying the value of an article having a predetermined price per unit weight comprising the steps of: periodically measuring the weight of the article; comparing each successive measured weight with a weight stored in a weight memory; in the event that any measured weight differs from the stored weight, calculating a new value from such measured weight and the predetermined price per unit weight; displaying the most recent calculated value; and storing in said weight memory the measured weight from which such displayed value was calculated.
Claim 12
Independent Claim
91 words
A method for calculating and displaying the value of an article having a predetermined price per unit weight comprising the steps of: periodically measuring the weight of the article; comparing each successive measured weight with a weight stored in a weight memory; in the event that any measured weight differs from the stored weight, calculating a new value from such measured weight and the predetermined price per unit weight; displaying the most recent calculated value; and storing in said weight memory the measured weight from which such displayed value was calculated.
Claim 13
Dependent Claim
41 words
A method for calculating and displaying the value of an article having a predetermined price per unit weight, as set forth in claim 10, and including the step of clearing said weight memory when the article exceeds a predetermined maximum weight.
Claim 14
Independent Claim
100 words
A method for calculating data based upon the weight of an article and a weight factor, comprising the steps of: storing the weight factor in a memory; periodically measuring the weight of the article; comparing each successive measured weight with a weight stored in a weight memory; in the event that any measured weight differs from the stored weight, calculating new data from such measured weight and the stored weight factor; storing the most recent calculated data in a memory; displaying the stored data; and storing in said weight memory the measured weight from which such displayed data was calculated.
