Abstract: An array of electrodes is comprised of a plurality of electrodes. Each electrode extends along a first direction X, and is periodically arrayed along a second direction Y perpendicular to X at a pitch pe. Each electrode further comprises a continuous periodic metal mesh having a square unit cell of edge length pm, the square unit cell having axes displaced by an oblique angle ? from X and Y The array is configured such that ?=arctan (a/b) and pm=n*pe/(m*sqrt(a2+b2)), where a, b, m, and n are positive integers. In this way, the electrodes repeat with a finite repeat length, while rendering the common edges of the repeating units visually imperceptible by a user.

Abstract: An illumination source includes a number of light emitting diodes (LEDs) operating at a first wavelength. Light from the LEDs illuminates a phosphor material that generates light at a second wavelength. A reflective polarizer transmits light at the second wavelength in a first polarization state and reflects light at the second wavelength in a second polarization state orthogonal to the first polarization state. The light at the second wavelength reflected by the reflective polarizer is directed back towards the phosphor material without an increase in angular range. In some embodiments the LEDs, having a conformal layer of phosphor material, are attached directly to the first surface of a liquid cooled plate. A liquid coolant contacts a second surface of the plate.

Abstract: The invention provides systems and methods for cooling semiconductor devices, such as those provided in concentrated photovoltaic (CPV) systems using a cold plate. The invention also provides using a material, such as a ceramic, to form that cold plate that matches or nearly matches the coefficient of thermal expansion (CTE) of a photovoltaic cell. Additionally, the cooling system may include fluidic passageways through which a fluid may flow, which may result in a transfer of heat between the fluid and the solid structure.

Abstract: A projection display system employs one or more color modifying aperture stops, such as apodizing aperture stops, to provide high contrast, balanced color and high throughput. One projection system includes a reflective liquid crystal-on-silicon light valve positioned with a polarizing beam splitter, such as a wire grid polarizing beam splitter, for each of the primary color component light paths to separately impart image information into each of the primary color components of light. A color combiner receives and combines the primary color components of light with imparted image information to provide light representing a polychromatic display image. At least one aperture stop is positioned along at least one of the primary color component light paths to balance relative intensities of the primary color components of light.

Abstract: Projection lenses and projection lens systems are telecentric between an illumination subsystem and a set of imagers. The lenses and systems can exhibit color fringing correction, uniform imager illumination, athermalization, and component articulation for improved imaging. The lenses and systems may be employed in display apparatuses, such as folded display apparatuses that have decreased footprint size, but long effective projection lengths.
