Publication number: 20120073657Abstract: Extremely high efficiency solar cells are described. Novel alternating bias schemes enhance the photovoltaic power extraction capability above the cell band-gap by enabling the extraction of hot carriers. In conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. In solar cells incorporating quantum wells (QWs) or quantum dots (QDs), the alternating bias scheme has the potential of extending such solar cell power extraction coverage, possibly across the entire solar spectrum, thus enabling unprecedented solar power extraction efficiency. Within such cells, a novel alternating bias scheme extends the cell energy conversion capability above the cell material band-gap while the quantum confinement structures are used to extend the cell energy conversion capability below the cell band-gap.Type: ApplicationFiled: September 26, 2011Publication date: March 29, 2012Applicant: OSTENDO TECHNOLOGIES, INC.Inventors: Hussein S.

Publication number: 20120033113Abstract: Emissive quantum photonic imagers comprised of a spatial array of digitally addressable multicolor pixels. Each pixel is a vertical stack of multiple semiconductor laser diodes, each of which can generate laser light of a different color. Within each multicolor pixel, the light generated from the stack of diodes is emitted perpendicular to the plane of the imager device via a plurality of vertical waveguides that are coupled to the optical confinement regions of each of the multiple laser diodes comprising the imager device. Each of the laser diodes comprising a single pixel is individually addressable, enabling each pixel to simultaneously emit any combination of the colors associated with the laser diodes at any required on/off duty cycle for each color. Each individual multicolor pixel can simultaneously emit the required colors and brightness values by controlling the on/off duty cycles of their respective laser diodes.Type: ApplicationFiled: October 21, 2011Publication date: February 9, 2012Applicant: OSTENDO TECHNOLOGIES, INC.Inventors: Hussein S. El-Ghoroury, Robert G.W. Brown, Dale A. McNeill, Huibert DenBoer, Andrew J. Lanzone

Patent number: 7889430Abstract: The dilemma encountered in most projection systems of having the etendue of the LED-based light source used often being much larger than the etendue of the imager used, causes such systems to have poor throughput efficiency. The etendue folding illumination systems of this invention being comprised of at least one folded collimator/concentrator having coupled into its input aperture an LED-based light source and having an output aperture characteristics that match the target etendue, overcome this dilemma by folding the light source etendue to match the target etendue of the projection system imager while efficiently conserving the flux generated by the light source.Type: GrantFiled: August 9, 2006Date of Patent: February 15, 2011Assignee: Ostendo Technologies, Inc.Inventors: Hussein S.

Patent number: 7835079Abstract: The viewing angle brightness sensitivity typically encountered in tiled rear projection display systems cannot be solely overcome by edge blending and calibration techniques. The rear projection array display-screen system of this invention, being comprised of a micro-structure array screen combined with a conventional diffusion screen, overcomes this viewing angle brightness sensitivity in both linear as well as matrix tiled rear projection display systems including those that use wide field-of-view projectors. The latter capability enables low form-factor and compact packaging of tiled rear projection display systems.Type: GrantFiled: April 10, 2007Date of Patent: November 16, 2010Assignee: Ostendo Technologies, Inc.Inventors: Hussein S.

Patent number: 5867400Abstract: The architecture and design method of an application specific processor having an instruction set which is matched to the needs of a specific application is provided. The application specific processor design method is based on using a library of pre-designed function blocks (111-113). These pre-designed function blocks encapsulate complex processing functions most commonly used by a specific application. Each of the pre-designed application specific function blocks is designed such that values of certain parameters of the encapsulated processing algorithm are implemented using registers which can be programmed with any desired value. Each of the pre-designed application specific function blocks is designed such that it can interface with a multi-purpose bus (110) through which the function block can accept invocation, reconfiguration, and data input/output routing commands.Type: GrantFiled: May 19, 1997Date of Patent: February 2, 1999Assignee: International Business Machines CorporationInventors: Hussein El-Ghoroury, Dale A.

Patent number: 5623684Abstract: The architecture and design method of an application specific processor ("ASP") is disclosed. The ASP is designed by integrating selected pre-designed application elements contained in a library. These selected application elements can communicate with each other via a bus. Post-synthesis tailoring of the synthesized ASP is accomplished by using an instruction program which sequences the invocation of each application element and provides reconfiguration and data input/output routing commands thereto. A power management design is incorporated within the application elements allowing the majority of the application elements to be turned on only during periods of invocation.Type: GrantFiled: May 17, 1994Date of Patent: April 22, 1997Assignee: Commquest Technologies, Inc.Inventors: Hussein S.
