Abstract: A reduced performance monitoring system for a tiltrotor aircraft includes a physical component of the tiltrotor aircraft configured to displace over time in response to an input, a simulation component configured to generate a simulated displacement response of the physical component, and a comparison module configured to compare a measured physical displacement response of the physical component to the simulated displacement response of the physical component.

Abstract: Generally, embodiment(s) disclosed herein may include modular luminaires and customizable luminaire combinations to produce desired overall illumination patterns, modular luminaires interchangeable between one or more lighting systems/luminaires having differing configurations, and/or luminaires with portions thereof formed primarily by optical waveguides, e.g., a wall sconce where primarily only waveguides extend from the wall. Further, contemplated throughout this disclosure is modification of panel-style and/or blade-style waveguide(s) for use with luminaire configurations having different sizes, shapes, and structural elements including as modular luminaires for use in creating further customizable lighting systems/luminaires.

Abstract: A lighting fixture incorporates a peripheral light emission feature, such as a peripheral waveguide and/or a peripheral reflector region. A peripheral light emission feature may at least partially surround a non-peripheral feature that may include a light-transmissive panel. At least one first light source may illuminate a peripheral light emission feature, and at least one second light source may illuminate a light transmissive panel. Control circuitry is configured to selectively adjust intensity and/or color temperature of the light sources to cause aggregate emissions of the lighting fixture (or a lighting system with multiple lighting fixtures) to dynamically change over time (e.g., with different intensities and color temperature), so as resemble a skylight or window. A viewer may thereby perceive at least portions of a space as being naturally illuminated.

Abstract: In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

Abstract: According to an aspect of the present disclosure, a luminaire comprises a housing and at least one waveguide comprising first and second opposite waveguide ends, a coupling portion disposed at the first waveguide end, and a light emitting portion disposed between the first and second waveguide ends. The luminaire is further arranged such that the first waveguide end is disposed adjacent a first luminaire end and the second waveguide end is disposed at a second luminaire end opposite the first luminaire end. Still further, the luminaire comprises at least one LED element disposed within the housing adjacent the coupling portion of the at least one waveguide such that the at least one waveguide provides a first illumination pattern and the at least one waveguide is interchangeable with another waveguide that provides a second illumination pattern.

Abstract: An edge lit fixture. A light engine comprises a compartment and at least one elongated lens that are attachable to a mount plate. The mount plate, an exterior surface of the compartment, and the lens define an internal optical cavity. A light strip is mounted to the mount plate within the optical cavity. One or more legs can be used to attach the fixture to an external surface, such as a ceiling T-grid. The light engine can be used with legs of varying size such that it can fit within ceiling openings having different dimensions. The assembled fixture defines an open area. One or more light engines are arranged around or through the open area such that light is emitted into the open area. The open area of the fixture allows for existing materials, such as a ceiling tile, for example, to function as a back side reflector panel.

Abstract: An edge lit fixture. A housing provides the basic shape and structure of the fixture. The housing is constructed from discrete segments including lens frames, side frames, and end frames, which can be used in many different combinations to create the desired fixture. The assembled housing defines an open central area. One or more light panels are arranged around the perimeter of the housing such that at least some of the light is emitted toward the central area. The open central area of the housing allows for existing materials, such as a ceiling tile, for example, to function as a back surface of the fixture.

Abstract: portable social distancing devices are described herein which, in some embodiments, are wearable by a user to maintain proper social distancing in any environment.

Abstract: A lighting fixture includes a fixture body, a lighting bay, a light source, and an auxiliary bay. The lighting bay is in a first portion of the fixture body. The light source is in the lighting bay, and is configured to provide light suitable for general illumination. The auxiliary bay is adjacent to the lighting bay in a second portion of the fixture body. The auxiliary bay includes a mounting surface suitable for mounting an auxiliary device in the auxiliary bay and an auxiliary bay frame surrounding the auxiliary bay, which supports and therefore allows for the installation of a removable auxiliary bay cover over the auxiliary bay. Providing the auxiliary bay in the fixture body allows auxiliary devices to be installed in a ceiling without any changes to the ceiling.
