Assignee:

Rockwell Collins, Inc. - Cedar Rapids IA

International Classification:

G02B 5/32
G02B 5/18
G09G 5/00

US Classification:

359 15, 359566, 359568, 345 7

Abstract:

An apparatus for providing an optical display includes an optical substrate for propagating light received from a light source, a first set of one or more switchable diffractive elements in the substrate, and a second set of one or more switchable diffractive elements in the substrate. Each diffractive element in the second set corresponds to a diffractive element in the first set. Each of the diffractive elements in the first and second sets is configured to switch between on and off states. One of the states is for diffracting light and the other state for allowing light to pass through. Each of the first set of diffractive elements is configured to diffract the light at an angle for propagation in the substrate. Each of the second set of diffractive elements is configured to diffract the light for display.

Appl. No.:

7/678759

Inventors:

Steven Robbins - Miami FL

Assignee:

Solar Outdoor Lighting, Inc. - Boca Raton FL

International Classification:

F21L 1508

US Classification:

362183

Abstract:

A self-contained solar powered light having a battery system where the battery container is mounted between two cantilevered arms on an upright vertical support. The light element is mounted at the distal end of one of the cantilevered arms. The photovoltaic panels are mounted on the upper cantilevered arm and point upward toward the sun. A computer is operably connected between the battery and the photovoltaic panels and the light element to determine when the light element should be actuated and deactuated based upon amperage produced by the photovoltaic panels. The vertical support has a U-shaped cross member which can engage poles with circular cross section or poles with external side flats. Threaded fasteners fix the vertical support onto the pole member.

International Classification:

G02B 27/01
G02B 5/18
G02B 27/10

Abstract:

A near eye optical display includes a waveguide comprising a first surface and a second surface, an input coupler, a fold grating, and an output grating. The input coupler is configured to receive collimated light from a display source and to cause the light to travel within the waveguide via total internal reflection between the first surface and the second surface to the fold grating; the fold grating is configured to provide pupil expansion in a first direction and to direct the light to the output grating via total internal reflection between the first surface and the second surface; and the output grating is configured to provide pupil expansion in a second direction different than the first direction and to cause the light to exit the waveguide from the first surface or the second surface.
