Abstract: A tool for evaluating the internal surfaces of tubular is provided, wherein one or more arms extend outwardly from the tool into contact with an inner wall of the tubular, and changes in the dimensions or condition of the inner wall result in changes in the position of the ends of the arms relative to the tool. This motion is converted, through an electromagnetic transducer, into an electrical signal, the accuracy of which deteriorates as the temperature of the tool changes. Calibration transducers are provided on the tool to provide correction factors to convert the electromagnetic transducer output into an accurate reading of the distance of the end of the arms from the tool thereby increasing the accuracy of the assessment of the inner wall of the tubular.

Abstract: Systems and methods allow units of produce to be traced back to the fields in which the produce was grown. In the field, a harvest form is completed with harvest information at the time of the harvest. In some instances, labels having unique codes are used to label the produce in the field, and an additional label is placed on the harvest form to associate a range of unique codes for an entire roll of labels with the harvest information on the form. In the alternative, the label can be read, such as with a hand-held device and associated with harvest information also entered through the hand-held device.
