The RF tag known in the art incorporated in a tire has a problem that it can easily get distorted when the stresses occurring in the running tire converge on its vicinity. The present invention provides a tire (1) configured to prevent distortion from occurring in the RF tag (50) incorporated therein. The tire (1) includes an RF tag structure (50A) which is constructed of the RF tag (50) covered with a coating rubber (51). The modulus of elasticity of the coating rubber (51) is higher than that of the rubbers of the adjacent members (13, 32) located adjacently on the respective axial sides of the coating rubber (51).

An assembly (8) for a central tire inflation system includes a housing having a first end and a second end. The housing defines a fluid conduit disposed through the first and second ends. The assembly also includes one or more sensors (205, 210) having a portion disposed in the fluid conduit. Further, a power source (245) is in electrical communication with the sensor. The assembly additionally includes a kinetic energy device (220) in electrical communication with the power source. The kinetic energy device may comprise a magnet (255) sliding on a guide (265). As an alternative, the kinetic energy device may comprise a turbine (275).

A method of performing a diagnostic test on a vehicle having at least one tire includes providing the vehicle with at least one sensor configured to detect a vehicle operating characteristic, a receiver configured to receive AM signals, a notification system, and a controller in electronic communication with the at least one sensor, the receiver, and the notification system, receiving sensor data from the at least one sensor and AM signal data from the receiver, analyzing the sensor data and the AM signal data, determining whether a first condition is satisfied, and in response to the first condition being satisfied, generating a first control signal to control the notification system to generate a notification.

A retightening notification apparatus include: a travel distance acquiring part that acquires a distance traveled after attachment, which is a distance that a vehicle traveled from when a wheel of a tire was attached to the vehicle by tightening a fastening component such as a nut or a bolt, to the present moment; and a notification control part that provides notification prompting retightening of the fastening component if the acquired distance traveled after attachment becomes equal to or greater than a retightening distance, which is determined in accordance with a state of use of the fastening component.

Systems and methods are provided for providing a tire pressure enhancing device for increasing the air pressure of tires mounted on a vehicle. For example, an air compressor may be coupled to an engine of a vehicle to compress air. The compressed air is then stored in the frame of the vehicle. The compressed air may be transferred to each tire through a hose via an access point in the frame.

A tire pressure monitoring system (30) includes a data acquisition portion (101) that acquires data indicating a tire pressure and a tire temperature of the tire, from a sensor (50FL), a sensor (50FR), a sensor (50RL), and a sensor (50RR) mounted to the tire; a puncture determination portion (103) that determines whether the tire is punctured, based on a puncture determination threshold defined by a relationship between the tire pressure and the tire temperature; and a warning processing portion (105) that generates a warning indicating that the tire is punctured apart from a warning of a drop of the tire pressure when the puncture determination portion (103) determines that the tire is punctured.

A tire pressure monitoring device includes a display, a receiver, a memory, and a processor. The receiver is configured to receive a first signal from a first sensor and a second signal from a second sensor. The memory stores a first and second communication protocols corresponding to the first and second sensors, respectively. The processor is in communication with the display, the receiver, and the memory and is configured to perform operations. The operations include selecting the first and second communication protocols based on the first and second signals, respectively, converting the first and second signals into first and second sets, respectively, of at least one of temperature data or pressure data corresponding to a first tire, and transmitting the first set and the second set of at least one of temperature data or pressure data to the display.

A Bluetooth tire pressure monitoring system (TPMS) includes a sensing host and a receiving host, and the sensing host includes a battery, a control unit, a Bluetooth transceiver unit, a boost/regulation circuit, a pressure sensing unit, an operational amplifier, a gravity sensing unit, a temperature sensing unit and a Bluetooth antenna. The Bluetooth TPMS utilizes low-power Bluetooth wireless communication technology to transmit and receive signals, so as to meet the requirement in low power consumption.

An aircraft tire monitoring system including a processor, and a data carrier having machine readable instructions that, when executed, cause the processor to, based on a plurality of sets of values indicative of tire parameters of aircraft tires, each set of values corresponding to an aircraft comprising a plurality of the aircraft tires, perform operations including determining a remedial action associated with each set of values. The operations include determining a priority associated with the determined remedial actions, and generating, based on the determined remedial actions, a list of aircraft, the list of aircraft ranked based on the determined priority of remedial action. The operations include causing a display device to display the list of aircraft, such that aircraft with a relatively higher priority remedial action are shown higher up the list on the display than aircraft with a relatively lower priority remedial action.
