An actuator device including: a case housing an expandable material, a moving part that can move in translation as a result of the expansion and/or contraction of the expandable material, and a heater to heat the expandable material. The device also includes: a position sensor which measures the current position of the aforementioned moving part; and a positioner to position the moving part, including a controller acting on the above-mentioned heater according to the current measured position.

A location device is provided, in which the device is configured to be carried by a tire and wheel assembly so as to locate a right or left position of the assembly in a vehicle. The device includes two magnetic sensors with axes of maximum sensitivity; a measurement circuit for measuring a signal across terminals of each of the magnetic sensors, the measurement circuit being able to deliver two periodic signals phase-shifted with respect to one another and each periodic signal being representative of variations in values of a magnetic field detected by a corresponding magnetic sensor during a revolution of the tire and wheel assembly; and a calculation processor programmed to determine, based on the phase shift between the two periodic signals, a direction of rotation of the tire and wheel assembly, and to deduce from the direction of rotation and a direction of travel of the vehicle, a right or left location of the tire and wheel assembly. The two magnetic sensors have their axes of maximum sensitivity oriented in parallel, and in the two magnetic sensors are configured to be placed on the tire and wheel assembly at distinct azimuths.
