A rim for wheel is described including a measuring system for detecting the vertical load applied to the wheel. The measuring system includes a sensor adapted to detect a deformation of the rim and to transmit a deformation signal to a processing unit. The processing unit receives an output signal of the sensor related to the deformation of the rim detected, and determines the vertical load applied to the wheel.

An apparatus includes a grid circuit having dimensions corresponding to an inner surface of a tire, a computational device coupled to the grid circuit, and a wireless communications device coupled to the computational device. The wireless communications device is configured to transmit detection of damage to the grid circuit. A computer-implemented method includes monitoring a grid circuit positioned in a tire to detect damage to conductors of the grid circuit, detecting damage to at least one of the conductors of the grid circuit, and transmitting information about the damage to a computer of a vehicle. A computer-implemented method includes receiving, from a computational device coupled to a grid circuit in a tire, information about damage to the grid circuit and outputting an indication that the tire is damaged.

A radiofrequency transponder comprises a radiating antenna consisting of a single-strand helical spring having an axis, a median plane, a pitch and a diameter for a given wire diameter, and an electronic portion located inside the radiating antenna. The electronic portion comprises an electronic chip electrically connected to a primary antenna that is electromagnetically coupled to the radiating antenna. The primary antenna has an axis parallel to the axis of the radiating antenna and a median plane superposed with the median plane of the radiating antenna. The primary antenna is circumscribed by a cylinder the diameter of which is larger than one third of the inside diameter of the radiating antenna. The radiofrequency transponder is characterized in that, in a first region of the radiating antenna, in which the latter is not located plumb with the electronic portion, the inside diameter of the radiating antenna is smaller than the inside diameter of the radiating antenna that does not form part of this first region.

A heavy goods vehicle tire has a radial carcass reinforcement, made up of a single layer of metal reinforcing elements anchored in each of the beads by a turn-up around a bead wire. The turn-up of the carcass reinforcement layer and the main part of the carcass reinforcement layer are coupled, and a radiofrequency communication module is placed in the coupling region at the interface between the turn-up of the carcass reinforcement layer and axially outwardly adjacent layer of rubber compound.

A functional component attachment seat (100) is used for attaching a functional component (200) to a tire inner surface (30) of a pneumatic tire. The functional component attachment seat (100) includes a surrounding wall (110) extended from the tire inner surface (30) to an inner side in a tire radial direction to surround a side face (210) of the functional component (200), and a flange (130) continued to the surrounding wall (110) to lock a peripheral part (221) at the inner side in the tire radial direction of the functional component (200). The functional component attachment seat (100) includes an engagement protruded part (131, 132) to be engaged with a notched part (231, 232) formed in a part of the peripheral part (221) and extended in a tire width direction or a tire circumferential direction.

A reader system for a tire with an integrated radio frequency identification (RFID) and tire pressure monitoring system (TPMS) sensor, in which the integrated RFID and TPMS sensor is mounted on the tire, is provided. The reader system includes at least one antenna that is external to the tire. The at least one antenna is mounted on a vehicle on which the tire is mounted in a location proximate the tire. The at least one antenna is in electronic communication with the integrated RFID and TPMS sensor. A reader is mounted on the vehicle and is also in electronic communication with the at least one antenna. The at least one antenna relays a signal from the integrated RFID and TPMS sensor to the reader. A display device is in electronic communication with the reader to receive and display data from the integrated RFID and TPMS sensor.

A pneumatic tire with a radio frequency identification and tire pressure monitoring system sensor combination includes a pneumatic tire. The tire includes a pair of bead areas, a ground-contacting tread disposed radially outwardly of the pair of bead areas, a pair of sidewalls, in which each sidewall extends from a respective bead area to the tread, a carcass extending toroidally between each of the bead areas radially inwardly of the tread, and an innerliner formed on an inside surface of the carcass. An integrated RFID and TPMS sensor is mounted on the innerliner and includes an RFID tag. The RFID tag includes an integrated circuit carried on a printed circuit board. The printed circuit board is formed with at least one opening to facilitate secure mounting of the circuit board to the innerliner. The integrated RFID and TMPS sensor also includes a TPMS sensor mounted on the RFID tag.

An assembly for mounting an electronics package to a tire includes an electronics package, a mount with a peripheral flange, and an attachment patch. The electronics package is connected to the mount, which is in contact with the tire. The attachment patch is connected to the mount and includes a central opening that is smaller than the peripheral flange. The attachment patch is further affixed to the tire.

This disclosure provides a tire formed of a body having multiple plies and a tread that surrounds the body. In some implementations, the plies and/or the tread include a resonator that generates a resonant signal in response to being activated by locally generated power or by an externally generated excitation signal. Multiple resonators formed of carbon-containing materials are distributed in the plies and/or tread to respond to changes to the tire by altering a characteristic of the resonant signal. Such alterations include frequency shifting of the resonant signal and/or attenuation of the resonant signal. The resonator can be configured to resonate at a first frequency when a structural characteristic of a respective ply or tread is greater than a level, and to resonate at a second frequency different than the first frequency when the structural characteristic of the respective ply or tread is not greater than the level.
