A pneumatic tire in accordance with the present disclosure comprises a first sound damper fixed to a tire inner surface and being made of a sponge material; a second sound damper disposed on a tire internal space side of the first sound damper, and being made of a sponge material; and a communication device retained between the first sound damper and the second sound damper, wherein the second sound damper has a hardness greater than a hardness of the first sound damper.

A tire electronics assembly includes a base and a plurality of modules. The base is mechanically attached to the tire and includes an electronic device. The base also includes a plurality of mechanical attachment elements arranged side-by-side in a row. Each module includes an electronic device and a mechanical attachment element. Each mechanical attachment element on a module is configured to releasably mechanically attach to any one of the mechanical attachment elements on the base. In this configuration, the modules are interchangeably mechanically attachable to the base in side-by side positions in row. The base further includes a plurality of electrical contacts arranged side-by-side in a row. Each module has an electrical contact that is configured to releasably electrically connect with any one of the electrical contacts on the base, whereby the modules are interchangeably electrically connectable with the base in side-by-side positions in a row.

An electronics assembly includes a base and a plurality of modules. The base is configured for mechanical attachment to a tire. The base includes an electronic device, and also includes a mechanical attachment element. Each module includes an electronic device, a lower mechanical attachment element, and an upper mechanical attachment element. The lower mechanical attachment element on each one of the modules is configured for attachment to the upper mechanical attachment element on any other one of the modules. In this configuration, the modules are interchangeably mechanically attachable to each other in a stacked arrangement. Each lower mechanical attachment element is also configured for attachment to the mechanical attachment element on the base. The modules are thus mechanically attachable to the base interchangeably with each other, which enables any one of the modules to be installed as the lowermost module in the stacked arrangement.

An electronics assembly is provided for use with a tire. The assembly includes a plurality of printed circuit boards, each of which includes an electronic device configured to sense a condition of the tire. Attachment pegs are provided to attach the printed circuit boards together in stacked positions that are spaced apart by the attachment pegs. Each attachment peg has a lower end portion configured to attach to any one of the printed circuit boards. Each attachment peg further has an upper end portion configured to attach to any other one of the printed circuit boards. This enables the printed circuit boards to be attached interchangeably between the stacked positions.

A tire electronics assembly includes a base and a plurality of modules. The base is mechanically attached to the tire and includes an electronic device. A plurality of mechanical attachment elements are arranged on the base in a circular array. Each module includes an electronic device and a mechanical attachment element. Each mechanical attachment element on a module is configured to releasably mechanically attach to any one of the mechanical attachment elements on the base. In this configuration, the modules are interchangeably mechanically attachable to the base in the circular array. The base further includes a plurality of electrical terminals arranged in a circular array. Each module has an electrical terminal that is configured to releasably electrically connect with any one of the electrical terminals on the base, whereby the modules are interchangeably electrically connectable with the base in the circular array.

A method or system configured for assessing the integrity of a sensor module mounted in a tire of a wheel or on an inner surface of the tire of the wheel.

A tire sensor dock for installing an electronic tire sensor module on the inner surface of a tire, including a base portion with an upper side and an underside, the underside configured for affixation on the inner surface of a pneumatic tire, and a body portion integrally formed on the upper side and configured to receive and securely capture a tire sensor in a fixed position and unchanging orientation relative to the tire sensor dock. The tire dock may include an energy generator which converts tire kinetic energy into electrical current provided to the tire sensor module.

An apparatus and method for measuring pressure and/or humidity, having at least one sensor for measuring pressure and/or humidity. The sensor has at least one capacitor having at least two electrodes that are arranged in a horizontal direction relative to one another along and on a flexible support material. At least one dielectric layer is arranged between the electrodes. At least one at least partially moisture-permeable and/or moisture-absorbing layer is arranged in some places on a side, facing away from a support material, of the electrode and/or the dielectric layer. The at least one electrode and/or the dielectric layer are arranged transversely between the support material and the moisture layer. In this way, a capacitance is at least partially changed by moisture hitting the dielectric layer, and a processing unit is designed and provided to measure and/or store this change, so as to create a capacitive moisture sensor.

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.

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.
