Tread depth sensing device and method for measuring same
First Claim
1. A tread depth measurement system for measuring a depth of a tread provided to a tire on a vehicle, the system comprising:
- an energy source for emitting a wireless signal to be transmitted to the tire;
a sensor for detecting a return wireless signal emitted from the tire to be transmitted in response to the wireless signal from the energy source;
a housing over which the tire is to roll while attached to the vehicle, said housing maintaining a separation between the tire and the sensor to prevent the tire from making direct physical contact with the sensor while the tread depth is being measured; and
a control unit operatively coupled to the sensor for determining the depth of the tread as a function of at least the return wireless signal detected by the sensor.

Abstract
A tread depth measurement system for measuring a depth of a tread provided to a tire on a vehicle. The system includes an energy source for emitting a wireless signal to be transmitted to the tire; a sensor for detecting a return wireless signal emitted from the tire to be transmitted in response to the wireless signal from the energy source; and a housing over which the tire is to roll while attached to the vehicle, said housing separating the sensor from the tire while the tread depth is being measured. A control unit is operatively coupled to the sensor for determining the depth of the tread as a function of at least the return wireless signal detected by the sensor.
