Abstract
An in-motion measuring system for determining the length and width of linearly-moving cuboidal objects through the use of object speed, the times during which four light beams oriented across the path of the object are obstructed by the object, and the angles of the light beams with respect to the direction of object movement. The height of an object may also be determined through use of a vertically-extending light curtain with horizontally-oriented light beams, or via an ultrasonic sensor.
