Abstract:
Heat dissipating devices and methods are disclosed. An example method may include evaporating a liquid working fluid, a resulting vapor phase to absorb heat. The method may also include condensing the vaporized working fluid back to a liquid phase to release the heat to an external environment. The method may also include returning the liquid working fluid back to the evaporation zone.
Abstract:
A first electrical path has a terminal, and a second electrical path has a terminal. First photovoltaic (PV) dies are electrically connected within the first electrical path. Each first PV die is adapted to convert light having a first wavelength range to electrical energy. Second PV dies are electrically connected within the second electrical path. Each second PV die is adapted to convert light having a second wavelength range different than the first wavelength range to electrical energy. A circuit is electrically connected between the terminals of the first and the second electrical paths to limit an absolute voltage difference between the terminals to no greater than a threshold voltage.
Abstract:
A substrate for an optical film stack is disclosed herein. A method of preparing a substrate for an optical film stack includes placing a polymer base material in a vacuum chamber, the polymer base material having a glass transition temperature (Tg) that is lower than a deposition temperature of an optical film layer to be deposited on the substrate to form the optical film stack. The method further includes depositing a capping layer on the polymer base material, the depositing taking place at a temperature that is less than or equal to 10% above the Tg of the polymer base material.
Abstract:
A color sensor array includes a plurality of sensors. Each of the plurality of sensors has a width dimension and a length dimension that is elongated with respect to the width dimension. The length dimensions of the sensors are substantially equal to one another and parallel to an illumination plane. Each of the plurality of sensors includes a face defined by opposing first and second elongated sides and opposing first and second non-elongated sides. The first non-elongated sides of the plurality of sensors are aligned with one another along an axis that is substantially perpendicular to the illumination plane.
Abstract:
A color measurement device includes a light pipe and a light source. The light pipe is oriented length-wise towards a color sample surface along a first axis that is non-perpendicular to the surface. A color sample is positioned on the surface. The light pipe has a near opening, a far opening, and a face at the far opening. The near opening is closer to the color sample than the far opening. The light source is positioned near the far opening of the light pipe, and is to output light along a second axis and into the light pipe at the far opening. The light reflects off the surface after exiting the light pipe at the near opening. The second axis is non-perpendicular to the face of the light pipe at the far opening. The light non-uniformly illuminates the color sample after exiting the light pipe at the near opening.
Abstract:
A device includes a pair of two partially transmitting optical surfaces positioned approximately parallel to each other and spaced apart. A high reflectance metal etalon coating is formed on each of the optical surfaces. An enhancing stack is coupled to the metal etalon coating on each of the optical surfaces.
Abstract:
An optical beam having a randomly and unpredictably variable input polarization state propagates through an optical system containing a first optical surface, for example a diffraction grating, a first adjustable mirror, and means for rotating the respective parallel (P) and perpendicular (S) plane polarization components of the optical beam relative to the first optical surface by ninety degrees, thereby generating a polarization rotated optical beam having reversed orientations of the S and P polarization components relative to the input. The optical beam is reflected from the first adjustable mirror, which redirects the optical beam onto an optimized location on the first optical surface, thereby reducing PDL due to propagation through the optical system. In some embodiments the optical beam location on the first adjustable mirror remains substantially constant during adjustment.
