A system can include a model to represent a volumetric deformation of a brain corresponding to brain tissue that has been displaced by at least one of disease, surgery or anatomical changes. The method includes decelerating the substrate from a process velocity to a low velocity, where the transfer velocity is greater than the low velocity and less than the process velocity, registering the substrate via the substrate registration system, and accelerating the substrate to the transfer velocity for image transfer. The moved polynomials ) are mapped into a polynomial ) of a polynomial ring)),obtained by applying an isomorphism between the fields of polynomials))and the polynomial ring))based upon the Chinese remainder theorem. The elastic joint for eyeglasses will maintain a comfortable tension to retain the eyeglasses on the user. In accordance with this invention the device comprises at least one input optical system comprising a collimating element receiving light rays emitted by the source and transmitting a beam of parallel rays towards an output optical system which forms a lighting or indicator lamp beam. A demodulator is provided to provide an estimation signal representative of an estimation of at least one parameter of the channel information.
