Abstract: A sensor includes a first pendular system articulated along a first axis, bearing at least one detector, and a second pendular system articulated along a second axis collinear with the first axis. Collector rings are mounted around the second axis, and electrical wires connect the terminals of the detector to the rings.
Abstract: A device for determining an angle of inclination of a ship has a curved guiding member fixedly connected with the ship and inclinable together with the latter, a rolling member arranged to roll on said guiding member in response to inclination of the ship and thereby inclination of said curved guiding member between a plurality of positions, and a recorder for recording the angle of inclination of the ship and operative in dependence upon a position of said rolling member on said curved guiding member.
