A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process includes acquiring first sound data collected by a first microphone and second sound data collected by a second microphone during traveling of a vehicle in which the first microphone is provided in vicinity of a front wheel and the second microphone is provided in vicinity of a rear wheel; and detecting a cavity under a road surface where the vehicle has traveled based on a difference between the acquired first sound data and the acquired second sound data.

A TPMS sensor for towable asset is configured to not only report a tire pressure but also whether the tire has moved. A telematics transceiver may then maintain a GNSS receiver in a sleep mode of operation (e.g., powered down) while the TPMS sensor does not report any motion.

Provided is a tire information acquisition device that includes a sensor unit including a sensor that acquires tire information, a first band that is for fixing the sensor unit (1) to a rim (R) and has an adjustable band circumferential length by fastening another end reversibly with a fastening portion provided to one end, and at least one second band that fastens the sensor unit and the first band integrally.

A system (1) for the management of data pertaining to a wheel service comprises: a database (2) including, for each tyre of a plurality of tyres, a tyre identification code; at least one tyre measurement parameter representing a physical quantity linked to the tyre or to the use thereof, and a related time mark, which indicates the time the tyre measurement parameter was captured; a knowledge dataset (3) containing reference data; a processor (4) having access to the database (2) and to the knowledge dataset (3) and programmed to process the at least one tyre measurement parameter and the reference data and to generate derived data.

Provided is a container structure for attaching sensors to tires and, more particularly, to a container structure for attaching sensors to tires, the container structure being able to prevent sensors attached to tires from being damaged by intense heat. The container structure can include: a bottom container that is attached to the inner liner of a tire; a top container that extends from the top of the bottom container and has an insertion space in which a sensor can be inserted; and a channel part that is formed on the inner side of the top container, in which the channel part is provided such that air can cool the sensor by flowing inside and outside with the sensor inserted in the top container.

A tire temperature monitoring system, method, and associated devices for installation into a vehicle. The system and method adapted to determine the optimal tire temperature for increased vehicle performance through the collection of tire temperature, various external conditions, historical data, and predictive algorithms to inform a user to the optimal temperature through a visual display.

A duplex Bluetooth transmission tire pressure system and a method thereof are provided. The system includes a Bluetooth tire pressure detector and a transceiver host, and the two can duplex Bluetooth transmit to each other, so that to complete locating and tire condition detecting. The transceiver host controls a locating program that controls the Bluetooth tire pressure detector to start or stop and limit the transmitting packet of the tire condition program of the Bluetooth tire pressure detector.

A power feeding device includes: a generator, the generator including a stator fixed to a wheel and a cylindrical rotor that rotates around a rotation axis of the wheel; an inertial member that is fixed to the cylindrical rotor and maintains a constant attitude by its own weight; a circuit board that is fixed to the stator and is mounted with a power feeding circuit to supply an output of the generator to a load; and a circuit receiving space that is provided inside the cylindrical rotor and receives a whole of the circuit board or an element that is mounted on the circuit board and protrudes from the circuit board.
