Abstract: A device for reducing sound from an air treatment unit includes, in one embodiment, an air treatment system, including a wall mount HVAC unit with a supply air opening and a return air opening. A supply air sound reducer is provided in communication with the supply air. The supply air sound reducer includes a housing defining a supply interior provided with sound reducing material. The sound reducing material is overlaid with a layer of perforated material. A return air sound reducer is provided in communication with the return air opening. The return air sound reducer includes a housing defining an interior return volume provided with sound reducing material applied to one or more inside surfaces of the interior return volume and a layer of perforated material disposed over the sound reducing material. Mid-structure including sound reducing material is disposed in each of the supply and return air assemblies.

Abstract: According to one or more aspects of DC-to-DC voltage conversion as taught herein, a DC-to-DC converter selectively operates in a first mode wherein an included linear pass output circuit supplies the output power from the DC-to-DC converter, in a second mode wherein an included charge pump output circuit supplies the output power, and in a third mode wherein the linear pass and charge pump output circuits operate in parallel to supply the output power. With this third mode, also referred to as a “dual” mode, wherein the linear pass and charge pump output circuits operate in parallel, the DC-to-DC converter keeps the more efficient output circuit on after it has begun switching to operation with the less efficient output circuit. Such switchover may be performed dynamically in response to changing operating conditions. Detected operating conditions may include input voltages, output voltages, and output load conditions.

Abstract: A sprinkler including a sprinkler head incorporating a nozzle; a spool fixed to the sprinkler head in proximity to the nozzle; a cage assembly loosely mounted on the spool, the assembly including a distribution plate at a first end of the assembly downstream of the nozzle and a first magnet at a second opposite end of the assembly upstream of the spool; a mounting element fixed to the assembly between the first and second ends, an inner edge of the mounting element loosely confined between upper and lower flanges of the spool; and a second magnet fixed to the sprinkler head, axially between the spool and the first magnet.

Abstract: A sprinkler head includes: a body assembly including an adapter, a nozzle, a spindle and a first magnet, the spindle supporting a spool having a pair of axially-spaced radially-oriented spool flanges; a nutating cage loosely mounted on the spindle, between the radial flanges of the spool, the nutating cage supporting a second magnet in close proximity to the first magnet; a water distribution plate carried by the nutating cage and adapted to be impinged upon by a stream emitted from the nozzle. The first and second magnets are arranged with like poles facing each other such that the second magnet is repulsed from the first magnet, but when the stream impinges on the water distribution plate, the second magnet is moved towards the first magnet, with magnetic repulsion force increasing and causing the nutating cage and the water distribution plate to tilt off axis.

Abstract: A sprinkler head includes a base; an arc adjustment ring; a nozzle and a stream deflector supported by an elongated stem carried by the base, the nozzle and the stream deflector cooperating to define an adjustable nozzle orifice; a water distribution plate secured to a shaft and located downstream of the nozzle; and a drive train operatively connected between the arc adjustment ring and the nozzle to rotate the nozzle relative to the stream deflector to adjust the nozzle orifice between limit positions. The stem is rotatable within the base upon over-rotation of the arc adjustment ring beyond the limit positions. The sprinkler head also incorporates a throttle control member movable axially relative to a flow restriction seat, to thereby adjust flow rate through the nozzle, and means for permitting rotation of the throttle control member with the shaft upon over-rotation of the shaft.
