A device (D) fixes, to the internal wall of a tire (P), an electronic box (100) for measuring parameters inside the tire, the device (D) associating the box (100) with a flexible receptacle (200) which, being fixed to the internal wall by an adhesion means (300), is preformed so as to accept and hold said box (100), remarkable in that said flexible receptacle (200) forms a compartment (210) equipped with an opening (220), by means of which said box (100) is introduced and which is bordered by an edge (221) extending externally and offering a contact surface (222) for the adhesion means (300) so that, once the receptacle (200) is fixed, said opening (220) is closed by the internal wall on which the receptacle (200) is fixed.

An apparatus for monitoring deflection of a tyre including a non-transitory memory, storing tyre behavior information which relates tyre deflection to tyre load and tyre pressure; and a controller in communication with the memory. The controller is configured to: receive load information which relates to a load on the tyre; receive pressure information which relates to a pressure of the tyre; and determine a deflection of the tyre based on the received load information, the received pressure information, and the stored tyre behavior information.

A method for pairing a measurement module with a wheel of a vehicle including, for each angular orientation signal associated with a specific wheel received by a computer, the steps of transmitting, by the computer, a measurement signal or a request to transmit a measurement signal to each module, measuring, by the computer or each module, a value of at least one parameter differentiating the signal, performing repetitions of the transmissions of measurement signals for each angular orientation signal received by the computer and storing values of the parameter, pairing a specific wheel with a measurement module when the values are substantially constant with a variation of less than 10% for the values, each wheel being associated with a module at the end of the method.

A flexible sensor unit is embedded in a tire. The flexible sensor unit includes a plurality of individual circuit boards. Each circuit board includes at least one electronic component. The at least one electronic component includes a radio frequency identification integrated circuit, a microcontroller unit, at least one sensor, a power source and a boost converter. Each one of a plurality of electrically conductive flexible connecting ribbons extends between the circuit boards. An end ribbon is electrically connected to at least one of the circuit boards. An antenna is disposed on the end ribbon. The antenna transmits data from the at least one sensor, as processed by the microcontroller unit, and identification data from the radio frequency identification integrated circuit, to an external reader.

A tire high temperature forecasting system includes at least one tire that supports a vehicle, and at least one sensor mounted on the tire for measuring a temperature of the tire. An electronic memory capacity is in a unit mounted on the tire for storing tire identification information. A processor is in electronic communication with the sensor and the electronic memory capacity, in which the processor receives and correlates the measured temperature, a time of the temperature measurement, and the tire identification information. Transmission means transmit the measured temperature, a time of the temperature measurement, and the tire identification information to a remote processor. The remote processor executes a forecasting model, and the forecasting model generates a forecast estimate. If the forecast estimate includes a predicted high temperature that is greater than a predetermined high temperature threshold for the tire, an alert is generated by the forecasting model.

A module includes a first partial housing and a second partial housing, wherein the first partial housing and the second partial housing together form a recess, a circuit board disposed in the recess; and an encapsulation mass, which closes the recess. A material from which the first partial housing is manufactured and a material from which the second partial housing is manufactured have a difference in thermal expansion coefficients that is at most 10% of the largest value of the two thermal expansion coefficients, the first partial housing includes a sealing structure and the second partial housing includes a counter-sealing structure, and at least one of the sealing structure and the counter-sealing structure is configured to extend into the other of the sealing structure and the counter-sealing structure.

The invention relates to a wireless tire pressure monitoring system provided on a tire or a rim of a vehicle. The system includes: a magnetometer for measuring a magnetic flux value; a pressure sensor for measuring a pressure value within the tire; a controller for receiving the magnetic flux value measured by the magnetometer and the pressure value measured by the pressure sensor, and determining whether the magnetic flux value fluctuates; and a wireless signal transmitter in signal communication with the controller, and controlled by the controller, wherein when the controller determines that the magnetic flux value fluctuates, the controller activates the wireless signal transmitter or raises the transmitting times per minute of the wireless signal transmitter and the wireless signal transmitter transmits a signal which represents the pressure value. The invention also relates to a method for operating a wireless tire pressure monitoring system.

An inflator disposed within a tubeless tire for inflating the tubeless tire. A rechargeable electric storage disposed within a tubeless for providing electricity. An electric air compressor is mounted on an inside surface of the rim of the tubeless tire within the pressure cavity of the tubeless tire. The electric air compressor and an air pressure sensor disposed within the tubeless tire runs by a controller. The electric air compressor has a compressed air inlet vented to atmosphere in a custom valve stem through a conventional hole of a valve stem in the rim of the tubeless tire. A motion activated power generator recharges the rechargeable electric storage. A short-range radio transmits measured pressure data for each tire to a central OBD module plugged into in the vehicle. The central OBD module connects through a smartphone indirectly or directly to a central server via a networked cellular radio tower.

A transmitter is attached to each of wheel assemblies of a vehicle and transmits transmission data to a receiver. The transmitter includes a nonvolatile memory that stores multiple types of protocols, a volatile memory that stores selection information, and a transmitting unit. The selection information represents a protocol that is selected from the multiple types of protocols stored in the nonvolatile memory and corresponds to the receiver. The transmitting unit transmits transmission data conforming to a protocol. The transmitting unit transmits the transmission data conforming to the protocol represented by the selection information when the selection information is stored in the volatile memory. Also, the transmitting unit transmits the transmission data conforming to all the protocols stored in the nonvolatile memory when the selection information is not stored in the volatile memory.
