An eye model system for remotely predicting the in-vivo performance of a vision altering optic includes a representative cornea, a dispersion medium, and a retinal surface. The corneal surfaces provide anatomical shape, optical power, and higher order aberration content. The dispersion medium mimics chromatic dispersion in an actual eye. The retinal surface is moveable to provide selected defocus. A humidity and temperature enclosure may be provided. Model eye elements can be tilted or decentered to simulate actual conditions. An associated method for remotely measuring the performance of a vision altering optic to predict its performance in-vivo includes making topography, wavefront, interferometry, PSF, MTF, or other optical and / or physical measurements of the model eye system with and without the optic in combination.

According to the invention, the process includes the steps of: a) taking a sagittal preoperative x-ray of the vertebral column of the patient to be treated, extending from the cervical vertebrae to the femoral heads; b) on that x-ray, identifying points on S1, S2, T12 et C7; c) depicting, on the said x-ray, curved segments beginning at the center of the plate of S1 et going to the center of the plate of C7; e) identifying, on that x-ray, the correction(s) to be made to the vertebral column, including the identification of posterior osteotomies to make; f) pivoting portions of said x-ray relative to other portions of that x-ray, according to osteotomies to be made; g) performing, on said x-ray, a displacement of the sagittal curvature segment extending over the vertebral segment to be corrected; h) from a straight vertebral rod (TV), producing the curvature of that rod according to the shape of said sagittal curvature segment in said displacement position.

There is described a one-piece friction body having a support and at least one friction pad disposed thereon, based on friction materials containing reinforcing fibers, thermoset binders and customary additives, in which the at least one friction pad is joined to the support integrally and positive-locking by means of reinforcing fibers penetrating the boundary layer between the support and the friction pad. There is further described a method of manufacturing this friction body, comprising the steps of bonding together the friction materials containing reinforcing fibers, thermosetting binders and customary additives for the support and the at least one friction pad in the desired shape and arrangement, needling the reinforcing fibers contained in the friction materials of the composite in such manner that at least the reinforcing fibers of the friction material of the at least one friction pad penetrate at least in part the friction material of the support and of the other friction pad, respectively, and curing the needled intermediate under heat and pressure in a pressing mold corresponding to the friction body to be manufactured.

An optical image stabilizer, in which a magnet and a coil are arranges such that they oppose each other. The Hall sensor is arranged such that one face thereof is opposed to one face of the magnet. The Hall sensor can easily detect the location of a group of lenses by generating a corresponding signal in response to a variation in magnetic force following a variation in the gap between magnets depending on the direction in which a group of lenses is driven, and simultaneously, in response to a variation in magnetic force that occurs when the group of lenses is displaced in the direction that intersects the direction of the gap.

A macrocell structure 20 having a honeycomb form is preheated to cure to a cure depth falling within a range where a flexibility of prepregs in the macrocell structure remains. Subsequently, prepregs 31, 32 are arranged along a side wall of the preheated macrocell structure 20, so as to make a preliminary structure 40. Then, the preliminary structure 40 is heated while the inside of the prepregs 31, 32 in the preliminary structure 40 is vacuumed. Thereafter, the preliminary structure 40 is heated while imparting an internal pressure thereto within a mold 5, so as to be cured, whereby a resin structure 1 is produced.
