Eye-tap for electronic newsgathering, documentary video, photojournalism, and personal safety

A novel system for a new kind of electronic news gathering and videography is described. In particular, a camera that captures light passing through the center of a lens of an eye of the user is described. Such an electronic newsgathering system allows the eye itself to, in effect, function as a camera. In wearable embodiments of the invention, a journalist wearing the apparatus becomes, after adaptation, an entity that seeks, without conscious thought or effort, an optimal point of vantage and camera orientation. Moreover, the journalist can easily become part of a human intelligence network, and draw upon the intellectual resources and technical photographic skills of a large community. Because of the journalist's ability to constantly see the world through the apparatus of the invention, which may also function as an image enhancement device, the apparatus behaves as a true extension of the journalist's mind and body, giving rise to a new genre of documentary video. In this way, it functions as a seamless communications medium that uses a reality-based user-interface.

Agile-beam laser array transmitter

An Agile-Beam Laser Array Transmitter (ABLAT) uses an array of emitters and an array of lenses to project electromagnetic beams over a wide angular coverage area in the far field. Differences in the separation pitches of the two arrays allows the ABLAT to project beams to contiguous and / or overlapping positions, depending on the ratio of the separation pitches and the lens focal length. Compared to other beam steering technology, the ABLAT is a smaller, lighter, and more efficient means of projecting beams over wider angular coverage areas. Various embodiments can be used in any beam steering application, including, but not limited to: free-space optical communications; light detection and ranging (lidar); optical scanning (e.g., retinal or bar-code scanning); display projection; image capture; optical character recognition; scanning laser microscopy; non-destructive testing; printing; facsimiles; map making; web inspection; color print processing; phototypesetting and platemaking; laser marking; material processing; DNA analysis; and drug discovery.
