Abstract
The present invention is a novel technique and system that allows the pressure of a tire to be remotely monitored by sensing a tire parameter indicative of the tire's pressure without mounting any device on the tire itself, while the tire is or is not rotating. In the illustrative embodiment, a tire parameter indicative of the pressure inside the tire, such as the temperature, acoustical signature, or shape of the tire, is measured remotely with a remotely mounted sensor. The measured parameter is compared to a range of known acceptable limits for that particular parameter, and a warning signal is generated if the measured parameter is not within that range of acceptable limits.
Claims6
An apparatus for remotely monitoring a parameter of a tire, said apparatus comprising:
- an acoustical transducer located remotely from said tire which detects and converts vibrational sound waves from said tire into an electrical signal indicative of an acoustical signature of said tire;
- a measurement processor which monitors said electronic signal, compares said monitored electronic signal with a set of acceptable threshold limits for said electronic signal, and generates a warning signal if said monitored electronic signal is not within said set of acceptable threshold limits.
A method for detecting an unacceptable condition of a tire, comprising:
- remotely detecting vibrational sound waves from said tire;
- converting said detected vibrational sound waves into an electrical signal indicative of an acoustical signature of said tire;
- comparing said electronic signal with a set of acceptable threshold limits;
- and
- generating a warning signal if said electronic signal is not within said set of acceptable threshold limits.
