A method of operating a multi-junction photovoltaic cell with junctions connected in series includes operating each junction at a different, respective maximum power point. A photovoltaic circuit includes: at least one multi-junction photovoltaic cell, comprising at least first, second, and third terminals; a first junction of the photovoltaic cell positioned intermediate the first and second terminals; a second junction of the photovoltaic cell positioned intermediate the second and third terminals; and a device for independently setting current flow through the first junction and the second junction to allow for maximum power point operation of each junction, the device for setting current flow being connected to the second terminal.

Three-terminal two-junction photovoltaic cells and method of use

One embodiment provides a method that includes displaying Boolean combinations of two or more bit planes.

Hybrid data planes

Disclosed are embodiments of a system and method for processing an image. An image processing unit includes a processor unit and a control unit. The processor unit receives an incoming video signal. The control unit defines image frames from the video signal. The image frames have bit planes in a plurality of spatial segments for manifestation on a spatial light modulator. The control unit also defines on and off states for a solid state light source. The control unit modulates the solid state light source at a modulated level during at least one bit plane such that illumination of the solid state light source at the modulated level is equally applied during the at least one bit plane for each of the plurality of spatial segments.

Image display system and method

A projection system includes a modulator and an Offner relay. The modulator is to modulate light in accordance with sub-frames of a frame of image data. The Offner relay is to differently aim, in accordance with each sub-frame, the light as modulated.

Offner relay for projection system

A projection assembly includes a dichroic beam splitter having first and second crossed dichroic surfaces, at least one interference type light modulator panel optically coupled to the dichroic beam splitter, and at least one filter at least partially between the light modulator panel and the dichroic beam splitter.

Light modulator assembly

A beam splitter includes a first member having at least a first dichroic layer, and a second member having at least a second dichroic layer, the first member being crossed relative to the second member.

Beam splitter

A projection lens assembly is provided that includes first, second, third, fourth, fifth, and sixth lenses. The second, third, fifth, and sixth lenses of the projection lens assembly form a double gauss-type lens assembly. The first lens is configured to provide telecentricity and the fourth lens in configured to correct aberrations due to variations in the third lens.

Projection lens assembly

A floor printer has a printing device and a fiducial nozzle along a bottom of a housing. The fiducial nozzle deposits a marks on a medium. The printing device forms an image on the medium.
