Abstract: An at least one acoustic sensor in form of a microphone configured for coupling with a tire pressure monitoring system and tire pressure monitoring system unit sensor to generally detect an acoustic signal within a tire interior space generated by a tire as the tire travels across a road surface. The detected signal can be used by various vehicle systems to generally determine a tire condition, such as, but not limited to, tread wear, tread depth, tire health, road condition, road characterization, status of noise reducing foam, and active noise cancelling.

Abstract: A tire mountable on a vehicle wheel includes: a tread section; and a tire side section to be mounted on the vehicle wheel, the tire side section being continuous with the tread section. The tire side section includes: a first area extending in a circumferential direction with substantially equal radii from an axis of the tire and being adjacent to the tread section; and a second area extending in the circumferential direction with substantially equal radii from the axis of the vehicle wheel and disposed between the first area and the vehicle wheel. The second area includes discontinuous recesses in an outer surface of the tire side section.

Abstract: A tire damage detection system for a vehicle includes: a tire; at least one sensor disposed in association with the tire to detect a noise signal when the tire rolls on a road surface to move the vehicle, the noise signal having a plurality of frequency peaks in a frequency spectrum of the noise signal; and a processor to monitor target frequency peaks of the frequency spectrum to detect damage of the tire, and to generate an alert signal in response to the detection of the damage of the tire.

Abstract: A method for rapid differential diagnosis of infection using supercritical fluid chromatographic separation of quorum sensing molecules as biomarkers for infection agents.

Abstract: A tire for a vehicle includes: a tread extending in a circumferential direction about a rotational axis of the tire; and wear indicators disposed in the tread and spaced apart from each other to be arranged in the circumferential direction. A harmonic noise signal caused by the tire when the tire rolls on a road surface to move the vehicle has neighboring first and second frequency peaks in a frequency spectrum of the harmonic noise signal, and the number of the wear indicators is in a range of 16 to 96 to generate, and when the tire rolls to move the vehicle at a speed in a target range, the wear indicators cause an additional frequency peak positioned between the first and second frequency peaks in the frequency spectrum when the tread is worn to reach a wear threshold.

Abstract: An acoustic sensor for coupling with a tire pressure monitoring system to generally detect an acoustic signal corresponding to a noise generated by a tire as the tire travels across a road surface. The detected signal can be used by various vehicle system to generally determine tire tread wear or depth and for use in active noise cancelling within the vehicle.
