Abstract: The invention relates to a method for controlling the production of a magnet (12) using a sensor able to emit a presence signal for a magnetic induction and defining a measuring axis, the magnet (12) being a permanent magnet with symmetry of revolution relative to its axis, called mechanical axis, the magnet (12) having a center and a maximum dimension, the method comprising at least the following step: a) performing a first measurement of a component of the magnetic induction produced by the magnet u(12) sing the sensor, b) performing a second measurement of a component of the magnetic induction produced by the magnet (12) using the sensor, and c) calculating the angular deviation of the equivalent magnetic moment of the magnet (12) from the first measurement and the second measurement.

Abstract: An electrochemical accumulator, including a casing, at least two electrodes and an electrolyte contained in the casing. There is a ferromagnetic material contained in the casing and having remanent magnetization. There is also a magnetic sensor arranged outside the casing and capable of measuring a remanent magnetic field of said ferromagnetic material. There is further included a circuit configured to determine the temperature inside the casing as a function of the measured remanent magnetic field.

Abstract: 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.
