Patent CA-2014435-A1 (CA)
Inventor: MACECEK MIREK
IPC: G01M17/02
Filed: 1990-04-11
Abstract: A method and apparatus for non-destructive ultrasonic testing of tires is disclosed wherein an ultrasonic transmitter is positioned outside of the tire and applies pulses of ultrasound to the tire at a plurality of locations around the tire's circumference for transmission through the tire wall and receipt by an ultrasonic receiver located within the tire. The ultrasonic receiver generates signals in response to the received ultrasonic tranmissions and a computer processes these signals to generate characterizing data from which defects in the tire may be determined.  Signals representative of the defects are then processed to generate a graphic display illustrating the location of the defects within the tire.
