Abstract: An example configurable lighting device includes a controllable general illumination device configured to output illumination light sufficient for general illumination of an area and a display configured to output light as a representation of an image into the area. The display is co-located with the general illumination device such that an available output region of the display towards the area at least substantially overlaps an available output region of the general illumination device towards the area. The lighting device has a light output surface configured and located such that light output from the general illumination device and light output from the display propagate out via the light output surface. The lighting device also has a noise reduction structure.

Abstract: Lighting devices are disclosed. One lighting device includes a housing, a light source, and a panel. The light source is mounted within the housing and configured to emit light sufficient for general illumination of an area. The panel is supported by the housing at a location to receive light from the light source at one or more light input surfaces of the panel and output the received light from the light source via a light output surface of the panel facing the area. The light propagates within material of the panel from the one or more light input surfaces to the light output surface. The light output surface of the panel comprises a noise reduction structure.

Abstract: Disclosed herein is a lighting system including a luminaire having a lighting device and a sound reduction device. The lighting device includes an illumination output surface, which is at least partially reflective with respect to an audio wave from outside the luminaire. The lighting device also includes an illumination light source configured to generate illumination light for emission through the illumination output surface for illumination of an area. The sound reduction device includes a pick up microphone and an audio output source. The pick up microphone is configured to detect incoming audio waves in a vicinity of the luminaire. The lighting system further includes a circuitry including a sound reduction controller coupled to the pick up microphone and the audio output source of the sound reduction device. The sound reduction controller is configured to operate the audio output source to control sound at least in vicinity of the illuminated area associated with the incoming audio waves.

Abstract: An example lighting device has a luminaire. The luminaire includes an illumination light source matrix including illumination light sources configured to be driven by electrical power to emit light rays for illumination lighting. The luminaire further includes an optical lens positioned and configured to extend over the illumination light source matrix and including an input surface coupled to receive incoming light rays emitted by the illumination light sources and an output surface. Both the input surface and the output surface each include various portions to refract or total internally reflect the incoming light rays emitted by the illumination light sources passing through to shape or steer the illumination lighting into an outputted beam pattern. A coupled illumination light source driver selectively controls the illumination light sources individually or in combination to adjust the outputted beam pattern from the optical lens.

Abstract: An example lighting device has illumination light sources, each configured to be independently driven. The device further includes an optical lens positioned over the illumination light sources. The optical lens has a number of aspheric or spheric convex surfaces, including an input surface and an output surface. The input surface includes an input peripheral portion and an input central portion. The input peripheral portion extends from the illumination light sources and curves from a region of the illumination light sources towards the input central portion. The input central portion curves towards the illumination light sources. The output surface includes an output lateral portion, an output shoulder portion, and an output body portion. Another example uses optical-to-electrical transducers, e.g. light detector or photovoltaic devices, in combination with the optical lens, for light reception transducer applications.

Abstract: The examples herein relate to assembly techniques and structures for an electrowetting cell, e.g. a fluid lens, a fluid prism or a single cell that may support both variable lens and variable prism functions. The resulting cell structure, for example, may support both beam shaping and steering functions, e.g. supporting use of the same electrowetting cell structure for a wider variety of optical processing applications. The resulting cell may be used in combination with an optical/electrical transducer or an array of cells may be used with a transducer in systems for a various light input and/or output applications.

Abstract: A supercavitating projectile is disclosed that has deployable fins. The fins are pivotally coupled to the body of the projectile. The fins have two primary states: stowed within a recess at the surface of the projectile and deployed to a radially-extended position relative to the body of the projectile. The fins deploy as the projectile leaves its launch tube. The fins function as a control surface, interacting with the wall of the vapor cavity in which the supercavitating projectile travels.

Abstract: A surface ship, deck-launched anti-torpedo projectile is disclosed. The projectile has a blunt-end nose to create a cavitating running mode. The nose has a gradual, stepped, right-circular cylindrical or conic geometry. In some embodiments, the projectile includes a plurality of tail fins that are dimensioned and arranged to be within the generalized elliptical cavity that shrouds the projectile in the cavitating running mode.
