A method for detecting a change in the rolling radius of a tire and a method for monitoring the state of the tire are based on the analysis of signals representing an actual speed of a vehicle on which the tyre is fitted and a speed of rotation of the wheel bearing the vehicle.

An inspection device comprises movable equipment (6) driven relative to a stand (7) and fitted with at least one inspection gauge (14, 15). The device also includes a measurement system (30) comprising a contactless transceiver system (30a) for emitting and receiving a light beam (F) along a path in which there is arranged a target (30b) that is securely mounted to the first inspection gauge, the transceiver system being secured to the stand, and delivering measurements continuously of the position of the first inspection gauge relative to the stand (7). A processor unit (31) is provided that means for detecting when the measurements of the position of the inspection gauge delivered by the transceiver system (30a) cease varying, in order to determine that contact has occurred between the inspection gauge and the container.

An overhead transport vehicle includes a lift stage to transfer an article, a winding drum to overlap and wind a suspension attached to the lift stage, and a controller to control a rotation amount of the winding drum to control a lifting/lowering amount of the lift stage. The controller is configured or programmed to execute a first processing including calculating, as individual values of the overhead transport vehicle, an individual value of an entire length of the suspension, an individual value of a diameter of the winding drum, and an individual value of a thickness of the suspension, and a second processing including calculating a rotation amount of the winding drum with respect to a lifting/lowering amount of the lift stage.

A device (9, 9a) for estimating a current wheel diameter of a wheel of a rail-based vehicle on a predetermined network of routes includes an interface (8) for collecting vibration data (5) of at least one wheel acting on the rail-based vehicle as an acceleration of the rail-based vehicle. The vibrations detectable using at least one wireless sensor (2a, 2b, 2c, 2d) arranged proximate the at least one wheel. A computing unit is configured for generating a predicted speed on the basis of the vibration data (5). A comparator unit is configured for estimating a wheel diameter based on differences between the predicted speed and an identified, corresponding ground truth speed (17).

A method comprises checking whether a motor vehicle is driving based on the incremental sensor units, checking whether the motor vehicle is driving in a straight line based on a driving direction sensor unit, checking whether each wheel is slide-free and slip-free based on the incremental sensor units, determining the distance driven by each wheel based on the sensor value of the respective incremental sensor unit and the radius to be iteratively determined of the wheel of a previous iteration, determining the distance driven by the motor vehicle based on the distance driven by each wheel, determining the radius to be iteratively determined of the wheel based on the distance traveled by the motor vehicle and the sensor value of the respective incremental sensor unit, verifying that a validation condition is met and then repeating the aforementioned steps.
