Abstract: Optical systems and methods are provided, which combine see-through view of the real world and display source images using a conical optical combiner cut to have flat surfaces normal to the viewer line of sight. The conical shape minimizes interferences in the view of the real world as the edges of the optical combiner are tangent to the viewer vision field of view and the inner part of the optical combiner is semitransparent. Additionally, the optical system comprises a beam splitter, a shutter(s) for attenuating or blocking the see-through path and may employ polarizing element to improve the contrast between the scene observation and the projected display and thus enabling selective viewing of either. The system may also be configured to enable diopter adjustment and virtual display distance adjustments.

Abstract: A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.

Abstract: A map data structure and method and system for obtaining geographic information. Raw map data is converted into map data structure by generating an attribute layer for each geographic attribute according to a defined line pattern and line width, and defining a bit-array of fixed bit-length for each element of a grid representing geographic coordinates, where a bit value of “1” is assigned if a respective attribute is present at the grid element location and a bit value of “0” is assigned if the respective attribute is absent. A map image depicting selected geographic attributes may be generated and displayed from map data structure, by sequentially scanning each bit in bit-array in descending order of priority, for each grid element of selected location, and if binary value of scanned bit is “1” then attribute layer associated with bit is displayed according to assigned color value if attribute selected for display.
