Abstract: Human stabilization platforms may include a support structure configured to rigidly support a person. A rail may extend longitudinally from proximate a portion of the support structure configured to receive the person's head thereon to proximate a portion of the support structure configured to receive the person's lower legs thereon on each lateral side of the support structure. Each rail may include selectable attachment structures distributed along at least a portion of the longitudinal length of the rail. The selectable attachment structures may be configured to receive modular accessories to be secured to the human stabilization platform. The selectable attachment structures may include a channel including alternating enlarged sections and constricted sections.

Each handle may be configured to enable manual handling and transport of the human stabilization platform.

Abstract: The design of a high efficiency, variable performance vaneaxial fan, requires the utilization of typical fan and single stage compressor design methodologies. To be able to replace multiple fans, the variable vaneaxial fan design must be capable of operation at several different flow rates and total pressures. These operation points can be met by varying motor revolutions per minute (RPM) or geometric parameters such as the hub diameter, tip diameter, as well as blade geometry including number of blades, pitch, spacing, and length. An ideal design with variable performance can replace a family of current fan designs by providing the capability for efficient operation over a range of flow rates and total pressures. This level of variability would not only allow the fan to respond to changing environmental conditions but also to be fit into systems with different characteristics.
