Abstract: A luminaire including an acoustic base,a lens in the acoustic base, and at least one light emitting device above the lens.

Abstract: A syringe pump to deliver heparin to into the blood circuit of a hemodialysis system. The syringe pump is configured to receive a syringe having a plunger movable within a lumen of an elongate tubular member. The syringe pump may include a housing having a recess configured to receive at least a portion of the syringe, a drive mechanism for moving the plunger within the lumen, the drive mechanism comprising a motor and a lead screw; and a grabber mechanism. The grabber mechanism includes a control arm, back panel, and upper and lower control fingers, the control fingers each have first and second ends, and a curved portion therebetween having a width, an interior edge, and an exterior edge, wherein the first ends of the upper and lower control fingers are coupled to the control arm via first and second spring hinges.

Abstract: A luminaire configured for perimeter lighting, and having improved features for adjusting one or more lighting characteristics of said luminaire. In one example, the luminaire comprises a light bar structure that may be rotated relative to a housing structure of the luminaire. Additionally, the luminaire may have a light scoop structure for redirecting a portion of light emitted from the light bar structure. Further, an angle of the light scoop structure may be adjusted relative to the housing structure of the luminaire, and independently of the light bar structure.

Abstract: A liquid mixing unit including a base unit, a magnet in a magnet recess in the base unit, an outer cylinder, an inner cylinder that is sized to fit in a central cavity in the outer cylinder, and a mixing unit in the inner cylinder.
