US Patent:

7738750, Jun 15, 2010

Filed:

Apr 30, 2008

Appl. No.:

12/113033

Inventors:

Alan C. Graham - Cupertino CA, US
Ronald P. Bevis - Morgan Hill CA, US

Assignee:

Agilent Technologies, Inc. - Santa Clara CA

International Classification:

G02B 6/28

US Classification:

385 24, 385 48

Abstract:

The multiplexer/demultiplexer has a planar reflector, a planar first filter element and a planar second filter element offset from the first filter element in a first direction to receive light reflected and transmitted from a first location on the first filter element. The first and second filter elements have orthogonal surface normals. The reflector is parallel to the second filter element and is offset therefrom in a second direction, orthogonal to first direction, to receive light reflected and transmitted from a second location, offset from the first location in the second direction, on the first filter element. The first and second filter elements each transmit and reflect light in non-overlapping wavelength ranges, and one of them has a band-pass or band-stop transmission characteristic.

International Classification:

G02B 6/34

US Classification:

385 24, 385 15, 385 31, 385 33, 385 36

Abstract:

The optical multiplexer system comprises an optical multiplexer, an output path and an adjustable beam steering element. The optical multiplexer comprises an input port characterized by an original acceptance range. The output path is disposed relative to the optical multiplexer such that a light beam incident on the input port within the original acceptance range enters the output path. The adjustable beam steering element is located adjacent the input port and is adjustable such that a light beam incident on the beam steering element within an enhanced acceptance range enters the output path as an output beam. The enhanced acceptance range is at least angularly greater than the original acceptance range.

International Classification:

G02F 1/1335

US Classification:

349 9

Abstract:

A light modulation assembly and an image projector utilizing a plurality of such light modulation assemblies are disclosed. The light modulation assembly includes an optical element, a pre-polarization filter, an image modulator, and an analyzer polarization filter. The optical element has an input port for receiving a light beam. The optical element directs the light beam onto the pre-polarization filter that removes light having a linear polarization in a first direction. The light leaving the pre-polarization filter illuminates the image modulator. The light leaving the image modulator is filtered by the analyzer polarization filter to remove light having a linear polarization with a predetermined direction relative to the first direction. The light leaving the analyzer polarization filter exits the optical element through an output port. A plurality of such assemblies can be combined with a beam splitting assembly to provide an image projector.

International Classification:

F24J 302

US Classification:

126445

Abstract:

A method of making a solar heat energy collecting system which comprises: forming a potentially foamable, resinous base layer containing a blowing agent; applying a printing composition to the surface of the potentially foamable, resinous base layer in the form of at least one continuous path extending from one edge point to another edge point of the potentially foamable, resinous base layer, the printing composition comprising a blowing inhibitor and a release agent; applying a top surface layer to the surface of the printed potentially foamable, resinous base layer which adheres thereto except in those areas containing the blowing inhibitor and release agent; heating the potentially foamable, resinous base layer to decompose or to activate the blowing agent in those portions of the potentially foamable, resinous base layer not lying under the blowing inhibitor and release agent, whereby such portions are blown and expand to extend and stretch upwardly so as to form upright walls of foamed, relatively lower density resinous material extending substantially vertically from the main portion of the resinous base layer, while those other portions of the potentially foamable, resinous base layer lying under the blowing inhibitor and release agent remain relatively unaffected; and supplying a fluid medium to those printed areas of the potentially foamable, resinous base layer lying over the blowing inhibitor and release agent, whereby the top surface layer is moved upwardly to form at least one continuous open channel extending from one edge point of the resinous base layer to another edge point of the resinous base layer and capable of conducting a heat transfer fluid medium therethrough. The inventive concept also relates to the solar heat energy collecting systems resulting from such methods.
