Abstract: A code made up of wedge-shaped elements representative in binary code for character reading of information. The area covered by the wedges is equivalent to selected printed characters and the reading is accomplished by a scanner which is pulsed at precise intervals or which is dynamic in operation, i.e. continuously reading or sensing the wedge as the scanner or the code is moved in a direction from one to the other end of the wedge in either an increasing or a decreasing area thereof. The scan profiles of the wedges are indicated during continuous reading thereof or from the reading or sensing thereof at precise points therealong and such profiles are then changed into transition profiles to determine polarity of change in timing or position of the information.
