Abstract: A whole building air quality control system includes an indoor air quality (IAQ) component having at least one control state, a plurality of sensors configured to measure a plurality of building conditions of a building space, and a controller communicably coupled to the IAQ component and the plurality of sensors. The controller includes memory storing a desired air quality index (AQI). The AQI includes a categorical variable. The controller is configured to iteratively modify a control state of the IAQ component using a machine learning algorithm until the plurality of building conditions of the building space satisfy the desired AQI.

Abstract: A system can determine a first measure of particulate matter generated from particulate sources disposed within a structure based at least in part on occupant data for the structure. The system can determine a second measure of particulate matter generated from an environment comprising particulate sources disposed outside the structure. The system can predict a service life for a filter based at least in part on the first measure of particulate matter, the second measure of particulate matter, and properties of the filter. The system can present an indication of the predicted service life for the filter.

Abstract: A method for limiting loads in a wind turbine by using measured loads or wind speed to increase the minimum pitch angle for extended periods. The minimum pitch angle will be allowed to relax down to the default when load excursions diminish. The method will allow turbines to capture more energy by operating in higher wind speeds and/or utilizing larger rotors without additional loss of fatigue life.

Abstract: A swivel mount for a spray head configured to be at least partially recessed within a mounting surface of a wall.

Abstract: An aspirator configured to be received within a shower fitting for generating a negative pressure in response to water flow.

Abstract: A faucet assembly including a mounting base and an upper faucet assembly. A cam fastener releasably couples the upper faucet assembly to the mounting base.

Abstract: A plaster guard for a wall mounted faucet valve assembly. The plaster guard includes a body having a central opening configured to receive the valve assembly, and a coupler configured to couple the body to the valve assembly.

Abstract: A top mounting faucet assembly comprising a mounting plate that may be mounted to a sink surface, a waterway tube, a faucet body housing, and a locking mechanism. The waterway tube is housed within the faucet body housing, to form a removable faucet assembly. The locking mechanism is attached to the mounting plate. This removable faucet assembly is mounted upon the mounting plate by attaching the faucet assembly to the locking mechanism.

Abstract: A plaster guard configured to define a recess within a wall around a pipe nipple for the subsequent recessed mounting of a fluid delivery device.

Abstract: A pivoting sleeve assembly for aligning a fluid delivery device perpendicular to a mounting surface when the fluid delivery device is mounted to a wall, the pivoting sleeve assembly made up of a fluid delivery device housed within a sleeve, the sleeve having a lower tubular portion and an upper arcuate portion, and an annular pivot ring, the inner surface thereof having an arcuate shape to conform to the shape of the upper arcuate portion of the sleeve, so that the sleeve may pivot within the contours of the pivot ring. This allows the sleeve to orient the fluid delivery device for proper mounting to the surface.

Abstract: A twist-on or wire-nut electrical connector having a rigid, electrically insulative shell, a flexible, heat-shrinkable, electrically insulative skirt, and a coil spring within the body for gripping wires which are inserted therein. The provision of a flexible, heat-shrinkable electrically insulative skirt allows for a safer, more secure connection into which more wires or wires with larger diameter insulation can be inserted. When heat is applied, the skirt will shrink around the inserted wires forming better insulation from moisture, providing a more secure mechanical connection, providing a better electrical insulation for wires with their own electrical insulation removed to insert into the connector, and allowing more or larger diameter wires to be inserted and secured. Unlike prior art connectors, the lower skirt either entirely contains or is directly adhered to the open end of the shell and is heat shrinkable.

Abstract: A pivoting sleeve assembly for aligning a fluid delivery device perpendicular to a mounting surface when the fluid delivery device is mounted to a wall, the pivoting sleeve assembly comprising a fluid delivery device attached to a fluid supply, a sleeve, attached to and surrounding the fluid delivery device, the sleeve having an inner surface and an outer surface, and having a lower tubular portion and an upper arcuate portion directly above the lower tubular portion, the arcuate portion curving upwards and outwards from the top of the lower tubular portion, and an annular pivot ring having an outer surface and an inner surface, the inner surface having an arcuate shape to conform to the shape of the upper arcuate portion of the sleeve, so that the sleeve may pivot within the contours of the pivot ring. This allows the sleeve to orient the fluid delivery device for proper mounting to the surface.
