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 device for converting radio-frequency energy into DC current, receiving at least one radio-frequency signal at input and generating at output a DC current capable of powering at least one load. The device has at least two conversion stages, each including: a radio-frequency filtering module, connected to a first input node of the conversion stage, configured to filter the radio-frequency signal; a voltage shift module, connected between a second input node of the conversion stage, the radio-frequency filtering module and an intermediate node of the conversion stage, configured to shift a voltage present at the first input node to the intermediate node; a voltage rectifier module, connected between the intermediate note, the second input node and an output node of the conversion stage, configured to rectify the voltage of the intermediate node and deliver a rectified voltage on the output node.
Abstract:
An optical system for detecting and tracking the eye movements of an individual. The system includes a frame, intended to be worn on the face of the individual, that includes a plurality of illumination sources. The system includes at least one contact lens, intended to be worn by an eye of the individual facing the frame, in which are encapsulated: an autonomous integrated circuit, a plurality of photoreceptors and a wireless communication transmitter. Variation in a signal (e.g., voltage or current) delivered by the photoreceptors allows not only the closure of the eyelid but also eye movements to be detected.
