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 the two 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.
