Abstract

A digital measuring device is provided for electronically determining measured distances, such as the dimensions of people or objects, as an integral part of a comprehensive system for manipulating and/or recording the measurement data. The digital measuring system of the present invention includes a digital tape measure for transforming measured distances into electrical signals or representations, and a control and display means for manipulating and recording the data received from the digital tape measure into a useful format. The digital tape measure includes a measuring tape with regularly-spaced markers and an electronic sensing means for detecting the passage of the markers. The control and display means can be incorporated into the digital tape measure itself, or alternatively it can be a separate unit.
