    Abstract: A control system for hazardous environments decreases flame paths, decreases punctures to the control system when installing interfaces, and increases safety. The control system may be characterized as a “one size fits all” controller that is able to automatically recognize a plurality of user interfaces. The controller has an enclosure to which the interfaces can be attached. The interfaces may interact with control electronics wholly contained in the enclosure using a variety of “wireless” mechanisms. Such mechanisms include reflecting light waves, infrared (IR) communication, radio-frequency identification, inductive coils, short-range wireless communication, camera images, piezoelectricity, and magnetism, and the like. The interfaces may include switches, indicator lights, smoke detectors, and the like.

    Abstract: A system includes a hot wire and a neutral wire configured to establish a closed circuit between a power source and a load. The system further includes first and second transformers as well as a sensor. The first current transformer is coupled to the hot wire and is configured to introduce a first test current, with a first polarity, into the hot wire. The second current transformer is coupled to the neutral wire and configured to substantially simultaneously introduce a second test current into the neutral wire. The second test current has the same polarity as the first test current. The sensor is configured to sense an asymmetry between the first and second test currents and is further configured to cause interruption of the closed circuit upon sensing the asymmetry.

    Abstract: A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.

    Abstract: A outdoor lighting fixture includes an enclosure, a heatsink, and an end-cap. The enclosure includes a cabinet and a cover that enclose control and power circuitry to provide power to illuminate a light source. The cabinet further includes an attachment face, and the extruded heatsink can be coupled to the attachment face. The extruded heatsink includes sides, a discontinuous plane of material formed with sides of the heatsink to provide a recessed mounting tray, and heat-conducting fins extending from the plane of material. The light source, which can include an LED light source, is coupled to the heatsink. The extruded heatsink can be coupled at one end to the attachment face of the cabinet at a position such that a space remains between the plane of material and a bottom edge of the attachment face, to permit water to drain from between the heat-conducting fins of the extruded heatsink.

    Abstract: A variable diameter termination includes an elastomeric tubular housing having a first portion with a first inner diameter, a second portion with a second inner diameter, and a third portion disposed between the first portion and the second portion and with a transition inner diameter. The elastomeric tubular housing is disposed on a tubular core that includes a first portion with a third outer diameter, a second portion with a fourth outer diameter, and a third portion disposed between the first portion and the second portion and with a transition outer diameter. The first portion of the elastomeric tubular housing is disposed over the first portion of the tubular core, the second portion of the elastomeric tubular housing is disposed over the second portion of the tubular core, and the third portion of the elastomeric tubular housing is disposed over the third portion of the tubular core.

    Abstract: A retrofitted light fixture can include a power source that delivers primary power. The retrofitted light fixture can also include at least one light fixture component of an existing light fixture, where the at least one light fixture component, as part of the existing light fixture, was directly coupled to the power source. The retrofitted light fixture can further include an adapter coupled to the power supply and the at least one light source, where the adapter comprises a controller, where the adapter receives the primary power from the power source, where the controller delivers power to the at least one light fixture component based on instructions.

    Abstract: A fitting for use with channel framing including an outer surface and a fitting groove formed in the outer surface includes a base comprising an inner face, an outer face, and sides extending between the inner face and outer face. The base is configured for insertion into the fitting groove of the channel framing. A spring member is mounted on the base and disposed generally above the outer face of the base. The spring member is configured to engage the outer surface of the channel framing when the base is inserted into the fitting groove. The base and the spring member form a clamp for securing the fitting in the fitting groove.

    Abstract: A frame piece of a frame for a luminaire is disclosed. The frame piece can include an inner surface, a first frame coupling feature disposed at a first end of the frame piece, and a second frame coupling feature disposed at a second end of the frame piece. The first frame coupling feature can be configured to mechanically couple to the second frame coupling feature of a first adjacent frame piece. The second frame coupling feature can be configured to mechanically couple to the first frame coupling feature of a second adjacent frame piece. The inner surface forms a partial opening through which a light source component can traverse.
