Abstract: This disclosure relates to suspended linear lighting fixtures that are arranged to accept lighting elements. Lighting fixtures according to the present disclosure comprise at least one body and at least one suspension mechanism. These lighting fixtures can be arranged such that electrical and mechanical connections can be provided at various locations along their length, rather than only at the distal ends of the fixtures. The fixtures can also comprise various connectivity features that allow further arrangements, designs and spatial adjustments. Lighting systems utilizing these fixtures are also disclosed.

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: 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: A sensor module is integrated into a lighting fixture. The sensor module includes one or more environmental sensors and can be readily installed in or removed from the lighting fixture. In one embodiment, a heatsink of the lighting fixture is configured to receive the sensor module. Readings from the environmental sensors may be passed to control electronics associated with the lighting fixture and used to control the light output of the lighting fixture. The readings may also be passed on to other lighting fixtures, which may also use the readings to control their light output.

Abstract: A lighting fixture is disclosed. In one embodiment, the lighting fixture includes a motorized pan-tilt mechanism having a head unit. The head unit either includes a light source or a receptacle for receiving and powering a light source. The motorized pan-tilt mechanism is capable of moving the head unit to control the direction in which light emitted from the light source is directed.

Abstract: Solid state downlights include a fixture that has a solid state lighting housing, a plurality of light emitting diodes within the solid state lighting housing and a junction box, and at least one mounting structure that is configured to releasably attach the fixture directly to a ceiling to mount the fixture within an opening in the ceiling.

Abstract: A suspension seat comprises a structural layer and a stretchable top layer above the structural layer. The structural layer comprises a cut-out. The perimeter of the cut-out is defined by a plurality of discrete members. The discrete members allow the buttocks (i.e., the tissue surrounding the ischial sacrococcygeal aspects of the skeleton) of a wheelchair user to enter into the cut-out with gradual pressure minimizing high pressure concentrations at the edges of the cut-out. The stretchable top layer bears load via tension as the wheelchair user buttocks deflects into the cut-out.

Abstract: Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.

Abstract: A mobile support assembly disposable between a stored orientation and an operative orientation including a frame having a front leg assembly including a pair of front legs, and a rear leg assembly including a pair of rear legs. At least one but preferably each of the front and rear leg assemblies include at least one cross member spanning the corresponding legs thereof. Each cross member is structured to have a variable length so as to effectively vary an overall width of the mobile support assembly and thereby facilitate a compact configuration of the frame when in the stored orientation. Further, at least one of the leg assemblies includes a lower portion wherein the wheels are included, the lower portion disposable into a non-operative storage position that at least partially defines a reduced longitudinal dimension of the frame when in the stored orientation.

Abstract: A multi-use mobile support assembly structured to be selectively used as a walker or a wheelchair including a frame having at least one adjustable frame segment structured to be disposed in either a first orientation or a second orientation. The frame may be foldable and includes at least a first front leg and at least a first rear leg, having wheel assemblies connected thereto for travel of the frame, whether used as a walker or wheelchair, over a different ground or support surfaces. In one embodiment, the first rear leg includes an upper member having a first end a second end and a lower member having a first end and a second end. The first end of the upper member may be pivotally connected to the first end of the lower member, and the lower member is removable with a corresponding wheel assembly or pivotal between an extended use position and a folded storage position.
