Provided is a tire information acquisition device. A sensor unit substrate on which a sensor for acquiring tire information and a power supply unit for supplying electric power to the sensor are disposed is provided, and a heat-insulating material is disposed at at least a periphery of the power supply unit.

The invention relates to a method for detecting the underflation state of a tire fitted on a vehicle, the method comprising the following steps: the step of determining a first contact patch measurement of a first tire fitted on the vehicle, the step of determining a second contact patch measurement of a second tire fitted on the vehicle, the step of comparing the first and second contact patch measurements and of inferring an underinflation situation therefrom if the difference between the two measurements is greater than a predetermined signalling threshold.

A pressure sensing assembly configured to be attached to a bicycle wheel having a tire and a rim mounted to the tire. The pressure sensing assembly includes a housing, a pressure transmitting member, a sensing chamber defined by the housing and the pressure transmitting member, and a sensing element. The pressure transmitting member is coupled the housing and has a central portion offset from the plane in a first direction. The sensing element is offset from the plane in a second direction opposite the first direction. The pressure transmitting member is configured to transmit a pressure in the tire to the sensing element via the sensing chamber.

A modular pavement slab comprises a body, a strain sensor array, and a sensor processor. The body includes a top surface, a bottom surface, and four side surfaces. The modular pavement slab is configured to be coupled to at least one other modular pavement slab via connectors along at least one of the side surfaces. The strain sensor array is retained within the body and is configured to detect a plurality of strains on the body resulting from vehicular traffic across the top surface of the body. The sensor processor is in communication with the strain sensor array. The sensor processor is configured to communicate input signals to the strain sensor array, receive output signals from the strain sensor array, and determine a plurality of time-varying strain values, each strain value indicating a strain experienced over time by a successive one of a plurality of regions of the body.

A tyre pressure sensing module for fitting to a rim of a wheel of a vehicle, the rim configured to accommodate a tyre. The tyre pressure sensing module comprises a pressure sensor apparatus configured to sense a pressure of a fluid retained within the tyre, and a sensor mount. The sensor mount is for securing the pressure sensor apparatus to the rim of the wheel. The sensor mount comprises a mounting area configured to be adhered to the rim and that is deformable to accommodate a radius of the rim.

A tire, cellular member, and sensor combination includes a tire. The tire includes a pair of sidewalls, a circumferential tread, in which the pair of sidewalls extends to the tread, and an innerliner. A cellular member is disposed on the innerliner and is formed with a sensor opening. A sensor is disposed in the sensor opening and is affixed to the innerliner.

A tire monitoring system may include first and second sensor elements, a circuit board, and a housing. The circuit board includes control circuitry coupled with at least one of the first and second sensor elements, wherein the control circuitry is configured to generate tire tread information based on an electrical response of at least one of the first and second sensor elements. The housing includes a housing material that surrounds the circuit board in a direction parallel with respect to a surface of the circuit board. Related methods are also discussed.

Provided are an in-vehicle reporting apparatus and a reporting system configured to prevent errors in reporting. The in-vehicle reporting apparatus stores a mounting position of each tire in association with identification information identifying the tire, a vehicle height acquisition unit acquires a vehicle height of the vehicle, a vehicle height determination unit determines whether the vehicle height is greater than or equal to a predetermined height, and a reporting unit reports information that depends on the mounting position of a tire stored in the storage unit in association with acquired identification information and on acquired air pressure information of the tire when the acquired vehicle height is not greater than or equal to the predetermined height, and does not report information that depends on the mounting position of the tire, when the acquired vehicle height is greater than or equal to the predetermined height.
