Abstract
A method includes transmitting first wireless signals towards a conveyor belt having multiple layers of material. The first wireless signals penetrate one or more layers in the conveyor belt. The method also includes receiving second wireless signals that have interacted with the conveyor belt. The method further includes identifying a condition of the conveyor belt using the second wireless signals and outputting an indicator identifying the condition of the conveyor belt. Identifying the condition of the conveyor belt could include identifying a thickness of at least one of the layers in the conveyor belt. This could be done by identifying pulses in the second wireless signals and using time of flight calculations.
