Abstract: A wearable device may include a first side, a second side, at least one electrode, and at least one thermocouple. The first side may be the side in contact with a subject, and the at least one electrode and the at least one thermocouple may be arranged on the first side.

Abstract: A luminaire having a diffuser structure configured to adjust a shadow cast from one or more LED light sources such that the shadow cast has a gradated transition between an area of illumination and an area of shadow. Accordingly, diffuser teeth may be configured to cast a plurality of shadows from a plurality of LED light sources such that a complex overlap pattern of shadows from the plurality of LED light sources forms a shadow gradient between an area of illumination and an area in shade.

Abstract: In an embodiment, a light fixture is provided that includes a housing, a lens configured to mount to the housing, a plate, and a light source located inside the housing. The housing may include a top panel, a pair of side panels, and a pair of end panels. The lens may have a length shorter than a longitudinal length of the housing, thereby creating a gap between the lens and at least one end panel of the housing. The plate may be attached to one of the pair of end panels. The plate may include a flat portion that attaches to the end panel and an angled portion that is angled away from the end panel. The angled portion may cover the gap between the lens and the housing.
