Abstract: Device for detecting neutrons with ionization chamber and with optical transduction comprising a plurality of optical cavities, each accommodating the free end of an optical fiber. The invention relates to a device (1) for detecting neutrons comprising at least one sealed ionization chamber (2) and with optical transduction with a plurality of cavities whose operation is each based on optical transduction using an optical fiber whose free end is within the cavity, which allows multipoint neutron-flux measurement, the measurement points being axially distributed.

Abstract: A vehicle brake mechanism that includes a pedal, a piston attached to the pedal, a spring associated with the piston and exerting a longitudinal force on the piston in a direction opposite the braking direction in order to bring the pedal to a resting position, and an autonomous brake module. A manual braking force on the pedal causes a longitudinal movement of the piston and displaces a transmitter element integrally joined to the piston. The autonomous brake module causes a movement of an intermediate plate that displaces the transmitter element and the piston, exerting a longitudinal force on the piston in the braking direction. The brake mechanism determines the force in the direction opposite the braking direction using a sensor situated on or in the intermediate plate and/or the transmitter element.
