Abstract: 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. The person is then localized at least in part based on pre-recorded items of information that correspond to localization, in the surroundings, of the fixed electrical appliance as identified by its magnetic signature.

Abstract: This invention relates to a continuously tunable external cavity light source and a process for adjusting the source. The source includes a laser, a diffraction grating placed on the laser's axis that together with the laser forms an external cavity, and an arm rigidly connected to the diffraction grating and having a mobile end permanently in contact with a slide plane perpendicular to the laser's optical axis. The source is tuned by shifting the diffraction grating. Fine adjustment of the slide plane is achieved by simultaneously rotating the grating and measuring the emissive power of the source as a function of the grating rotation. The number of jumps of the emissive power is counted with respect to the current injected, fine adjustment means are used in accordance with result of the count, and the counting and fine adjustment steps are repeated until the result of the count is zero.
