Abstract: A transparent optical module system or device comprising an optical architecture hierarchy based on a patch unit. In aspects, the transparent optical module comprises a display sparsely populated with pixels. The patch unit comprises one or more regions of display pixels, or a pixel pattern(s), and an associated lenslet, for example on a microlens array. The lenslet is capable of transmitting display-emitted light to an eye of the wearer of the transparent optical module, which then focuses the light to form a retinal image, which is seen or perceived by the wearer. The patch units can be combined further into patch groups, wherein members of a group serve a similar role in retinal image production as a patch unit and/or lenslet. This hierarchy allows the system to be scaled to larger and more complex systems.

Abstract: A near-eye display including a light source, an optical system, and a phase map including multiple pixels. The optical system is configured to receive illumination light from the light source and output the illumination light as an in-phase wavefront. Control logic of the near-eye display is coupled to variously program different phase patterns of the phase map at different times. The phase patterns are each to variously adjust phases of respective portions of the in-phase wavefront. For each of the phase patterns, the phase map is to form a different respective image in response to being illuminated by the in-phase wavefront.

Abstract: Systems and processes for measurement of the eyelid movements of a subject, which explores eyelids' electrical conductivity, namely the established fact that eyelids are acting as sliding electrodes moving over the cornea, is comprised of a system for generating a high frequency weak and harmless oscillating electromagnetic field in the proximity of the eyelid movement path without interference with the vision or activity of any such subject, therefore induces so-called Eddy Currents in the eyelid, which in its turn produce its own electromagnetic field with a value depended on the eyelid position; the interaction between the basic oscillating electromagnetic field and the field generated by the eyelid is changing electromagnetic field inductance, which will be measured with very high accuracy by means of resonance sensing electronics; such systems can transmit data from its detecting electronics to a remote monitor that compels no restrictions on operator activity.
