Abstract
Abstract Bar codes are shown for measurement of volumes of liquids, e.g., the amount of milk collected in a dairy milking operation, and correlation therewith to identification of the source of the liquid, such as a cow. In the preferred embodiment, infrared or laser scanners are used to scan bar codes to provide an input to a computer for correlating the container or the source of liquid with the volume of liquid, whereby complex volume measuring devices and operator measurements can be substantially eliminated. Similar techniques can be used to provide computer input data representing a wide variety of analog inputs; e.g., by providing a bar code scale for juxtaposition to a thermometer, the segments of the code along the scale being selected in accordance with the mercury level at a given temperature, simple analog-to-digital temperature data conversion and input is obtained. Methods and apparatus for providing machine-readability for a number of differing types of analog instrumentation are described.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
209 words
A method for converting an analog instrument that is adapted for visual-readability, to machine-readability, wherein the analog instrument is of the class having one or more means for indicating an analog quantity, each of the indicating means moving with respect to respective visually-readable scale indicia responsive to a total analog quantity being measured, the total analog quantity being represented by all of the one or more indicating means when read together, said method comprising the steps of: providing a plurality of bar-coded scales, one said scale for each of the one or more indicating means, each said scale comprising a plurality of bar-coded segments, each bar-coded segment encoding a number corresponding to a value for the analog quantity indicated by the corresponding indicating means when juxtaposed to the corresponding indicia; providing an encoded means for pointing to all of the one or more indicating means simultaneously in such a manner so as to point out a single one of said segments from each said scale; providing a programmable and freely movable bar code scanner; and programming said scanner to scan only predetermined combinations of said segments and encoded pointing means, such that said scanner is enabled to scan only said single one of said segments from each said scale.

Independent Claim
209 words
A method for converting an analog instrument that is adapted for visual-readability, to machine-readability, wherein the analog instrument is of the class having one or more means for indicating an analog quantity, each of the indicating means moving with respect to respective visually-readable scale indicia responsive to a total analog quantity being measured, the total analog quantity being represented by all of the one or more indicating means when read together, said method comprising the steps of: providing a plurality of bar-coded scales, one said scale for each of the one or more indicating means, each said scale comprising a plurality of bar-coded segments, each bar-coded segment encoding a number corresponding to a value for the analog quantity indicated by the corresponding indicating means when juxtaposed to the corresponding indicia; providing an encoded means for pointing to all of the one or more indicating means simultaneously in such a manner so as to point out a single one of said segments from each said scale; providing a programmable and freely movable bar code scanner; and programming said scanner to scan only predetermined combinations of said segments and encoded pointing means, such that said scanner is enabled to scan only said single one of said segments from each said scale.
Claim 3
Dependent Claim
101 words
Apparatus for converting an analog instrument which includes visually-readable quantity indicator means to machine-readability, said apparatus comprising a bar-coded scale having a plurality of bar-coded segments, each said segment encoding a unique number that is indicative of an amount of an analog quantity measured by said instrument, and means, responsive to said quantity indicator means, for ensuring that an unguided bar code scanner reads a single segment of said bar-coded scale upon scanning instrument, such that said segment read by said scanner correctly corresponds to said amount indicated for the analog quantity at its respective position by said quantity indicator means.
Claim 4
Dependent Claim
101 words
Apparatus for converting an analog instrument which includes visually-readable quantity indicator means to machine-readability, said apparatus comprising a bar-coded scale having a plurality of bar-coded segments, each said segment encoding a unique number that is indicative of an amount of an analog quantity measured by said instrument, and means, responsive to said quantity indicator means, for ensuring that an unguided bar code scanner reads a single segment of said bar-coded scale upon scanning instrument, such that said segment read by said scanner correctly corresponds to said amount indicated for the analog quantity at its respective position by said quantity indicator means.
Claim 5
Dependent Claim
76 words
The apparatus of claim 2 wherein said means for ensuring that a scanner reads a single segment of said bar-coded scale comprises additional bar coded indicia, said indicia being a part of a complete bar code, each of said segments comprising the remaining part of said complete bar code, whereby a bar code scanner is enabled to scan one of said segments only when said single segment is in juxtaposition to said additional bar code indicia.
Claim 6
Independent Claim
94 words
A system for converting an analog instrument having visually-readable quantity indicia to machine-readability, wherein the analog instrument also includes indicator means for pointing to one of the visually-readable quantity indicia responsive to an amount of the quantity, said system comprising a bar code scale having a plurality of bar code segments, each said bar code segment encoding a unique number corresponding to the quantity of a single indicium, and means for ensuring that an unguided bar code scanner scans only said bar code segment corresponding to the indicium pointed to by said indicator means.
