  • Fluid absorption and distribution enhancement systems
    Patent number: 9237976
    Abstract: Embodiments of a fluid absorption and distribution enhancement (FADE) product comprises at least one flow media layer, and at least one superabsorbent polymer layer.
    Type: Grant
    Filed: March 15, 2013
    Date of Patent: January 19, 2016
    Assignee: Cornerstone Research Group, Inc.

  • Variable performance vaneaxial fan with high efficiency
    Patent number: 9017038
    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.
