    Abstract: A contact lens, e.g., of the scleral type, having user-controllable colour changing. An electro-optical structure including at least one layer of a bistable electro-optical absorbent material, which, under the effect of the application of an electric field, can pass from at least one first stable state to at least one second stable state having different colorimetric absorption properties, and vice versa under the effect of the application of an electric field of opposite polarity. This change in state of the material leading to an alteration to the visible colour of the contact lens. The electro-optical structure extending in an annular region intended to cover the iris at least partially while leaving a central zone clear. An electronic circuit encapsulated in the lens and configured to subject the material to an electric field causing the change in state thereof in response to receiving a corresponding control signal.

    Abstract: A precoder for precoding a vector of information symbols is provided. The precoder includes a radius determination unit configured to determine a search sphere radius, the determination of the search sphere radius comprising applying a machine learning algorithm to input data dependent on the vector of information symbols and on a predefined precoding matrix; a sphere encoding unit configured to determine a perturbation vector from lattice points found inside a spherical region by applying a sphere search-based sequential algorithm, the spherical region having as a radius the search sphere radius, and a precoding unit configured to precode the vector of information symbols using the perturbation vector and a precoding matrix.
