摘要： A method of evaluating the Polarization Mode Dispersion (PMD) of an optical fiber by arranging the optical fiber at substantially zero tension on a surface, propagating prescribed evaluation optical signals along the optical fiber, measuring fiber Differential Group Delay (DGD) values in response to the evaluation optical signals, repeating at least once the acts of propagating and measuring, each time preliminarily inducing a change in a mode coupling of the fiber, and determining the fiber PMD on the basis of a calculated DGD average value. Changes in the polarization mode coupling of the fiber are induced by, moving at least a section of the fiber substantially orthogonally to the surface. An improved PMD evaluation apparatus includes a fiber arrangement surface adapted to have a fiber under test arranged thereon at substantially zero tension, and, operatively associated with the fiber arrangement surface, a fiber moving device activatable for moving the at least a section of the fiber substantially orthogonally to the fiber arrangement surface.

摘要： An apparatus for measuring the weight of a preform for optical fibres during a chemical deposition process for the formation of a preform is disclosed. The apparatus has at least one elastic constraint associated with at least one end portion of an elongated element made of a chemical deposition substrate for the formation of the preform, a device for inducing an oscillation, for example axial, on said elongated element, a device for detecting the frequency of oscillation of said elongated element, and a device for calculating the weight of the preform according to the detected frequency of oscillation. Advantageously, the device allows the realisation of a method for measuring the weight of the preform wherein the errors in measurement caused by thermal drift effects, by the axial distribution of the masses on the preform and by loads which are different from the mass of the preform in formation are reduced to below the required precision in measurement.

摘要： A timepiece movement with a movable element capable of being momentarily immobilized in any one of N discrete positions, and with a device including a lever and a first magnet integral with the lever, with N second magnets integral with the movable element and arranged along an axis of displacement, and with a magnetically permeable element arranged facing one polar end of the first magnet located on the side of the movable element. The polarity of the first magnet is reversed with respect to that of the second magnets. A first magnetic torque exerted on the lever has a first direction over a first section and a second direction, opposite to the first direction, over a second section of the distance between two successive stable positions, the first direction defining a return torque towards the movable element for a contact portion of the lever.

摘要： Timepiece movement including a mechanism, a spring barrel for driving the mechanism, and an equalization device connected to the spring barrel. The spring barrel includes a drum and a motor spring to exert a driving torque which is variable as a function of the degree of winding-up of the motor spring. The equalization device is driven by the spring barrel and exerts an auxiliary torque which varies as a function of the degree of winding-up of the motor spring to counter variations in the motor torque. The equalization device includes a first and second magnetic elements being displaced from each other by exerting a magnetic force which varies as a function of the relative position of the first and second magnetic elements and produces the auxiliary torque.
