Abstract: A contact lens, intended to be worn on the eye of a person, for automatically aiming in the direction of the eye. The contact lens includes:—a membrane suitable for covering the pupil and the iris of the eye;—at least two light sources encapsulated in the membrane, each suitable for emitting a light beam whose divergence is controlled in relation to the axis of the lens;—at least one interface for collecting and supplying electrical energy to the light sources, from outside the lens;—at least one electronic circuit suitable for activating the sources from the interface.

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 method for coding (k, r) data and a method for reconstructing data are provided. The coding method includes steps consisting in: dividing an initial datum a into k data blocks ai; grouping the k data blocks into r−1 subsets Sj of data blocks; generating, for each subset Sj, a linear function gj(a) defined as a linear combination of the data blocks assigned to said subset Sj; and generating r parity functions comprising a primary parity function f0(a) as a linear combination of the k data blocks ai, and r−1 secondary parity functions, each secondary parity function fj(a) being defined as the sum of the primary parity function f0(a) and of a linear function gj(a).
