Patent number: 9092982Abstract: An apparatus for measuring speed of movement of an object deforming lines of Earth's magnetic field includes a first and second magnetometer disposed on either side of a traffic roadway for the object and substantially perpendicular to the object. The magnetometers are configured for measuring deformation of Earth's magnetic field by the object travelling over the roadway. The apparatus also includes a processing unit configured for extracting, from each of the magnetometers, a measurement value corresponding to a quotient defined by a distance of the object with respect to the magnetometer divided by a speed of movement of the object, and for calculating a speed of the object from the measurement values and a geometrical disposition of the magnetometers with respect to one another and with respect to the traffic roadway.Type: GrantFiled: January 7, 2011Date of Patent: July 28, 2015Assignee: Commissariat à l'énergie atomique et aux énergies alternativesInventors: Antoine Robinet, Roland Blanpain

Method and system for locating a person and medium comprising instructions for performing the method
Patent number: 8476897Abstract: A method for localizing a person in surroundings equipped with fixed electrical appliances includes measuring an electromagnetic field radiated by one or more of these fixed electrical appliances with a magnetometer carried by the person, identifying a fixed appliance operating near the magnetometer by comparing the measured field with pre-recorded magnetic signatures. Each pre-recorded magnetic signature is associated with an electrical appliance present in the surroundings.
