Abstract
A comparing device for comparing major landmarks and the orientation of a master object to like characteristics of test objects includes a plurality of master sensors arranged in a predetermined pattern corresponding to a desired orientation and/or landmarks of a fixed master object for producing an output representative of the orientation of the fixed master object. A plurality of test sensors are arranged in the same pattern as the plurality of master sensors for sensing major landmarks and the orientation of a test object and for producing an output representative of the orientation and major landmarks of the test object. In addition, a comparison device compares the output of the plurality of master sensors to the output of the plurality of test sensors for providing a signal to indicate incorrectness of the test object corresponding to the desired characteristics of the fixed master object and subsequent ejection of the incorrect test object from the processing line.
