Abstract: A method for determining the angular position of a vehicle including a towing vehicle, a towing platform articulated on the towing vehicle, and a trailer articulated on the towing platform. The method includes camera acquiring a first image in a first reference position of the vehicle, and detecting at least one characteristic point of the trailer in the first position. The camera acquires a second image in a second position of the vehicle, and detects the characteristic point in the second position, the detected characteristic point being the same for each position. A position of the characteristic point is estimated in the first position and the second position of the vehicle by minimizing a cost function based on an iteration of different values of the height of the characteristic point in the first position of the vehicle and of the characteristic point in the second position of the vehicle. The angle of rotation between the trailer and the towing platform is determined based on the estimated position of the characteristic point estimated during the estimation step.

Abstract: A rotary position encoder includes a detection unit and a scale co-configured and co-operative to detect a relative rotational position and to generate a position output accordingly. The scale has a scale pattern according to a linear-feedback shift register (LFSR) pseudo-random code, which is a non-maximal length code having a seed value, tap positions, and modified least-significant bit position(s) of code words that satisfy rotary constraint by which each code word follows in sequence from the adjacent code word.

Abstract: A flatness roller includes a body having at least one cavity opening onto an outer surface of the body through a plurality of slots, two successive slots defining a lamella between them, each lamella being connected to the body by two connection portions. The flatness roller also includes at least one optical fibre having at least one strain sensor having a measurement axis. Each strain sensor is housed in a cavity and attached at a connection portion of a lamella, the measurement axis forming an angle less than or equal to 20° with a plane orthogonal to the axis of revolution of the body. Each strain sensor is configured to send an optical response wave representative of a strain of the strain sensor according to the measurement axis thereof.

Abstract: An optical tilt measurement apparatus includes an optical tilt sensor for use in sensing a tilt angle of a flat reflective surface around a pivot axis. The optical tilt sensor includes an optical emitter arrangement for emitting at least three beams of light so that each emitted beam of light is incident on, and reflected from, the flat reflective surface to form a corresponding reflected beam of light. The optical tilt sensor also includes an image sensor having a sensor area for detecting an intensity distribution of each of the reflected beams of light and outputting one or more signals representative of the detected intensity distribution of each of the reflected beams of light. The at least three emitted beams of light are emitted along at least three corresponding different emission paths. Each emission path extends from a corresponding emission point along a different corresponding emission direction.

Abstract: There is provided an optical encoding system including a photodiode array and a code disk opposite to each other. The code disk is arranged with multiple code slits at a ring area corresponding to the photodiode array. A length direction of each photodiode of the photodiode array has at least one deviation angle with respect to a length direction of the multiple code slits to reduce the total harmonic distortion in photocurrents.
