AUTOMATIC TIRE IDENTIFIER WITH THRESHOLD SETTING PROPORTIONAL TO THE RECEIVED SIGNALS

摘要

An automatic tire identification system starts with a tire having a black code printed on the tire tread. The tread and code are illuminated and the reflected energy is read and detected. The reflected energy from the tire tread and code is differentiated to produce a signal representative of the code read from the tire. The code is then decoded to determine the code printed on the tire tread.
