Abstract:
An illumination pump source is disclosed. The illumination pump source includes a set of power sources configured to generate a set of laser beams, with at least some of the set of laser beams configured to include illumination having different wavelengths. The illumination pump source also includes an optical fiber. The illumination pump source also includes one or more optical elements, the one or more optical elements configured to couple the illumination from at least some of the laser beams to one or more regions of the optical fiber.
Abstract:
A dual-mode active and passive gimbaled optical system including a mechanism for coupling an optical signal from an off-gimbal active-mode source into the on-gimbal passive-mode optical path. One example of the system includes a passive off-gimbal detector assembly configured to image emissive electromagnetic radiation from a viewed scene, and a receiver-path optical assembly, including on-gimbal objective optics, that directs the electromagnetic radiation to the off-gimbal detector assembly. The system further includes an off-gimbal active source that generates an optical signal, a gimbal bearing assembly that supports rotation of the gimbal and includes a centrally-located output ferrule mated to an optical fiber that transports the optical signal from the active source to the output ferrule, and an on-gimbal optical coupling element that receives the optical signal from the output ferrule and couples the optical signal into the receiver optical path to direct the optical signal toward the on-gimbal objective optics.
Abstract:
In one embodiment, a distance sensor includes a projection light source, a first light guiding means positioned to guide light emitted by the projection light source, a diffractive optical element positioned to split the light guided by the first light guiding means into a plurality of projection beams traveling in different directions, and an image capturing device positioned to capture an image of a field of view, including a projection pattern created by an incidence of the plurality of projection beams on an object in the field of view.
Abstract:
Illuminating devices are disclosed having plastic light-transmitting article(s) formed from a thermoplastic composition including a polycarbonate having repeating structural carbonate units according to the formula (I): in which at least 60 percent of the total number of R 1 groups contain aromatic moieties and the balance thereof are aliphatic, alicyclic, or aromatic. The composition also includes an epoxy additive having at least two epoxy groups per molecule and a phenolic diphosphite derived from pentaerythritol. The thermoplastic composition exhibits a dE (2000hrs.) value of less than 1.5 after 2000 hours of heat aging at 130°C, measured according ISO 11664-4:2008(E)/CIE S 014-4/E:2007 using CIE illuminant D65 and a 2.5 mm thick molded plaque of the thermoplastic composition.
Abstract:
Die Erfindung betrifft eine Beleuchtungseinrichtung für ein Kraftfahrzeug, umfassend einen Lichtleier (1) zur totalreflektierenden Leitung von Licht entlang einer Lichtausbreitungsrichitung, wobei das Licht von zumindest einer Lichtquelle (2) stammt und über zumindest eine Einkoppelfläche (3) an einer Stirnseite des Lichleiters (1) einkoppelbar ist. Der Lichtleiter umfasst ferner eine entlang der Lichtausbreitungsrichitung angeordnete Auskoppelfäche (4) zum Auskoppeln von Licht, welches an einer entlang der Lichtausbreitungsrichtung angeordneten Austrittsfläche (5) unter Aufhebung der Totalreflexionsbedingung aus dem Lichtleiter (1) austritt. Die erfindungsgemäße Beleuchtungseinrichtung zeichnet sich dadurch aus, dass die zumindest eine Lichtquelle (2), deren Licht über die zumindest eine Einkoppelfläche (3) einkoppelbar ist, eine Laserlichtquelle ist.

Abstract:
An interactive electronic device shell and light source may enable personalization and increased functionality of an electronic device. The shell may at least partially cover a light source and attach to an electronic device. The shell includes at least some transparent or translucent portions (e.g., light stencils) that enable light from a matrix of the light source to emit through the shell, thus causing a display of light from the shell. In some aspects, the electronic device may be linked with the shell and/or the light source to control light emission through the shell. In various aspects, an illumined portion of the shell may have significance, such as revealing an artistic design or indicating a message based on activity of the electronic device.
Abstract:
This disclosure generally pertains to a method for manufacturing a distributed optical fiber scrim comprising a functional optical fiber, the functional optical fiber scrim thus manufactured, and composites in which an optical fiber scrim is incorporated. The present disclosure describes a variety of textile scrims, particularly adhesively bonded nonwoven scrim materials, each comprising at least one optical fiber with a continuous path across at least the length or width of the fabric. Such optical fiber scrims may be useful as sensor components (for example, as a detector of breakage, strain, pressure, or torque), as illumination components (for example, in a variety of light-providing applications), or as data-distribution components, either alone or in combination with other materials, such as fabrics, films, foams, and the like.
