Abstract: A method for designing an electrode pattern for obtaining an optical element, the method including: determining a refractive index profile for an active material included in the optical element; determining, based on the refractive index profile, a voltage profile indicative of a voltage distribution to be applied along the radius or optical axis of the active material to cause a variation in a refractive index of the active material corresponding to the refractive index profile; generating an electrode pattern, with a pair of end-terminals, constituting a set of segments associated with a set of resistances; and obtaining the optical element by depositing the electrode pattern on the active material for application of the voltage distribution along the radius or optical axis of the active material when a set of drive voltages are applied to the pair of end-terminals.

Means for selectively controlling the active material in a central portion and a plurality of sectors of the active optical element is employed. The central portion and the plurality of sectors are arranged around an optical axis of the active optical element, wherein the plurality of sectors surround the central portion. A processor of the optical apparatus is configured to generate a drive signal to drive said means to selectively control the active material in at least one of: the central portion, at least one of the plurality of sectors to produce a given optical power thereat.

Abstract: An eye-tracking apparatus. At least one light source and a plurality of sensors are arranged at a periphery of a first surface of at least one lens. A frame is employed to hold the at least one lens. A processor coupled to the at least one light source and the plurality of sensors is configured to control the at least one light source to emit light towards the user's eye, control the plurality of sensors to sense reflections of the light off a surface of the user's eye, and process sensor data pertaining to the sensed reflections to determine a gaze direction of the user's eye.

Abstract: An electronic device or electronic device assembly may comprise a first portion and a second portion, a first magnet disposed inside the first portion and rotatable about a pivot axis with respect to the first portion, and a second magnet disposed inside the second portion and rotatable about a pivot axis with respect to the second portion. The first and second magnet may be configured to rotate so that the first and second magnets magnetically engage each other when the distance between the first and second magnet is equal to or smaller than a first distance.

Abstract: A peripheral display apparatus that is wearable by a user. The peripheral display apparatus includes at least two light sources and at least one processor coupled to at least two light sources. The at least two light sources include a first light source and a second light source arranged at a first peripheral portion and a second peripheral portion of a field of view of user, respectively, first peripheral portion and second peripheral portion being positioned at opposite horizontal ends of field of view. The at least one processor or at least one external processor communicably coupled to at least one processor is configured to generate at least two images including a first image and a second image, wherein at least one processor is configured to display first image and second image simultaneously at first light source and second light source, respectively.

Abstract: A display system including eye-tracking means, first image renderer, second image renderer, optical combiner and processor is described. Eye-tracking data is processed to determine gaze directions of user's eyes. Gaze location and gaze velocity and/or acceleration of user is determined based on gaze directions of user's eyes. It is detected whether or not gaze has been fixated for predefined time period based on gaze location and gaze velocity and/or acceleration of user. If gaze has been fixated, input image is processed to generate and render first image and second image substantially simultaneously. Projection of rendered first image and projection of rendered second image are combined optically by optical combiner to create extended-reality scene. If gaze has not been fixated, input image is processed to generate and render first image via first image renderer, whilst switching off or dimming second image renderer.
