Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
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.
Claim 2
Independent Claim
86 words
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.
Claim 3
Dependent Claim
17 words
An apparatus in accordance with claim 1 , wherein: said parameter comprises a pressure of said tire.
Claim 4
Dependent Claim
16 words
An apparatus in accordance with claim 1 , wherein: said acoustical transducer comprises an ultrasound detector.
Claim 5
Dependent Claim
15 words
An apparatus in accordance with claim 1 , wherein: said acoustical transducer comprises a microphone.
Claim 6
Dependent Claim
15 words
An apparatus in accordance with claim 1 , wherein: said acoustical transducer comprises an accelerometer.
Claim 7
Independent Claim
66 words
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.
