Abstract: A turbomachinery engine can include a fan assembly with a plurality of variable pitch fan blades. The fan blades are configured such that they define a first VPF parameter and a second VPF parameter. The first VPF parameter is within a range of 0.10 to 0.40 and is defined as the hub-to-tip radius ratio divided by the fan pressure ratio. The second VPF parameter is within a range of 1-30 lbf/in2 and is defined as the bearing spanwise force divided by the fan area. In certain examples, the turbomachinery engine further includes a pitch change mechanism, a vane assembly, a core engine, and a gearbox.

Abstract: An audio stream is received from one or more of a plurality of microphones. A relationship between the audio stream and a user is detected. The detection is based on the audio stream from the plurality of microphones. The user wears a wearable device that includes the plurality of microphones. A direction of the audio stream is determined. The determination is based on the audio stream from the plurality of microphones. An alert to the user wearing the wearable device is output. The output is based on the direction of the audio stream. The output is also based on the relationship between the audio stream and the user.

Abstract: A security device is configured to limit access and prevent removal of a backflow preventer connected to a fire hydrant. The security device includes an upper enclosure rotationally and detachably coupled to a lower enclosure. The upper enclosure has an upper enclosure left end and the lower enclosure comprises a lower enclosure left end each being configured to accommodate a portion of the fire hydrant. An upper access door is attached to the upper enclosure and permits and restricts access to the backflow preventer. A side door is attached to the lower enclosure and permits and restricts access to the backflow preventer to install a hose to the backflow preventer. A plurality of height adjustment legs are attached to the lower enclosure to adjust a height of the lower enclosure from ground and to carry weight of the security device which avoids plastic deformation of the backflow preventer.

Abstract: A centrifugal processor is disclosed with includes an outer frame having an inner surface and an axis. At least one inner vessel positioned within the outer frame and is adapted to receive an object to be processed. A drive system rotate the inner vessel with respect to the outer frame and along the inner surface of the outer frame. The drive system includes a central shaft engaged with the vessel for rotating the vessel about the axis. An environmental control system is included which channels a secondary medium to or from the vessel to assist in the processing of the object. The environmental control system includes a manifold formed in at least a portion of the central shaft and adapted to channel the secondary medium. At least one port is formed in the central shaft and connected to the manifold. A conduit connects the port and the inner vessel for channeling the secondary medium between the manifold and the interior of the vessel.
