A device for measuring the tire pressure in a wheel of a vehicle provided with a pneumatic tire is accommodated in a shell-shaped housing which is arranged at the valve base of a tire valve. Provision is made that there is only a single location on the housing by which the housing can rest on the rim well of a rim of the wheel.

An adjustable tire inflation assembly for precisely inflating a tire to a desired pressure includes a tire inflation fitting that is fluidly attachable to a valve stem on a tire for inflating the tire. A pressure adjustment unit is integrated into the tire inflation fitting that is settable between a minimum pressure and a maximum pressure. The pressure adjustment unit senses the pressure within the tire when the tire is being inflated with the tire inflation fitting. A light emitter is coupled to the tire inflation fitting and the light emitter is turned on when the pressure adjustment unit senses air pressure within the tire inflation unit that matches the pressure to which the pressure adjustment unit is set. In this way the light emitter alerts the user that the tire has been inflated to the desired pressure.

A pressure array sensor module, comprising an array electrode board, a plurality of pressure sensing elements, at least one first conductive structure and at least one second conductive structure is provided. The array electrode board comprises a substrate and an electrode array disposed on the substrate and having a first electrode pattern and a second electrode pattern. Each pressure sensing element is disposed at a sensing position on the array electrode board, and comprises a top electrode layer, a bottom electrode layer and at least one pressure sensing layer disposed between the top electrode layer and the bottom electrode layer. The top electrode layer has a first lead. The bottom electrode layer has a second lead. The first conductive structure electrically connects the first lead and the corresponding first electrode pattern. The second conductive structure electrically connects the second lead and the corresponding second electrode pattern.

There are provided a system and a method of automatic tire inspection, the method comprising: obtaining at least one image capturing a wheel of a vehicle; segmenting the at least one image into image segments including a tire image segment corresponding to a tire of the wheel; straightening the tire image segment from a curved shape to a straight shape, giving rise to a straight tire segment; identifying text marked on the tire from the straight tire segment, comprising: detecting locations of a plurality of text portions on the straight tire segment, and recognizing text content for each of the text portions; and analyzing the recognized text content based on one or more predefined rules indicative of association between text content of different text portions at given relative locations, giving rise to a text analysis result indicative of condition of the tire.

In a tire inflation pressure detection device, a receiver functions such that, when an ignition switch is on, power is generated by a power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of a tire, and such that, when the IG is off, in each predetermined intermittent cycle power is generated by the power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of the tire. A transmitter determines whether a decrease in tire inflation pressure occurs, and when the decrease occurs, the transmitter transmits frames more frequently than before the occurrence of the decrease in tire inflation pressure at a shorter frame transmission time interval than a regular transmission cycle during a high-frequency transmission period.

A module for detecting a vibrational behavior of a mechanical component includes an attachment component configured to be rigidly mechanically connected to the mechanical component in order to absorb a mechanical vibration of the mechanical component, a circuit board including a circuit, the circuit board being configured to detect the mechanical vibration of the mechanical component and, based on the detected vibration, to wirelessly transmit a signal indicative of the vibrational behavior, and at least one spacer mechanically connecting the circuit board to the attachment component such that the mechanical vibration is transferable from the attachment component to the circuit board.

A vehicle measurement station utilizing at least one displacement sensor disposed on each opposite side of a sensor region of a vehicle inspection lane to acquire displacement measurement data, associated with a moving vehicle passing through the sensor region. Each displacement sensor is configured to acquire measurement data along at least three discrete and vertically spaced measurement axes. A processing system receives the acquired data for evaluation, identification of outlier data points, and for determining a measurement associated with a characteristic of the moving vehicle, such as vehicle velocity, axle alignment, wheel alignment, or dimensions.

A system to perceive the structure of a tire chamber is presented herein. The system includes: a memory, controller, wheel, vehicle tire, and sensor. The memory includes executable instructions. The controller is in turn configured to read and execute the executable instructions. The wheel is adapted to connect to a vehicle axle. The tire is connected to the wheel. The sensor is located within the interior chamber of the tire. The sensor is moreover configured to measure a selected portion of the tire chamber. The sensor is further configured to communicate the measurement to the controller. The executable instructions enable the controller to: operate the sensor so as to make measurements of the tire chamber; retrieve (from the sensor) measurement information of the tire chamber; and generate tire-chamber-perception information from the measurement information of the tire chamber.
