Patent number: 11236723Abstract: The present invention provides a system of wind turbines connected to a single unit electric generator to produce electrical power whereby the wind turbine blades rotate coaxially with a main rotor shaft instead of perpendicular to the shaft axis. In this respect, the wind turbine rotor can face the wind from any direction and does not need to be pointed into the wind to be effective, thus, eliminating the need for a yaw system. Moreover, translation of mechanical to torque of the main rotor drive allows the drive components such as the gearbox and generator to be placed near the ground of each wind turbine improving accessibility for maintenance.Type: GrantFiled: July 2, 2018Date of Patent: February 1, 2022Assignee: WiSys Technology Foundation, Inc.Inventor: Md Maruf Hossain

Publication number: 20210000637Abstract: An external urine collection system for collecting urine excreted by a user through the user's external urethral orifice includes a urinary assembly having a sleeve and a cup that define a collection chamber. The sleeve can be attached to an area around the user's external urethral orifice by an adhesive. The cup can be coupled to the sleeve through a male connector and female connector that form a liquid tight seal between the sleeve and the cup. An outlet is defined by at least one of the sleeve and the cup for draining urine excreted by the user into the urinary assembly.Type: ApplicationFiled: September 22, 2020Publication date: January 7, 2021Inventors: Eric Jon VanMiddendorp, Taylor S. Sims, Abby A. Merritt, Phillip N. Keshavarzi, Matthew S. Dykstra, Tyler D. Kramer, Amanda E. Stark, Chelsea M. Edge, Brandon D. Johnson, Jill M. Morris, John Farris, Andrew T. Heuerman, Kevin T. Weaver, Md Maruf Hossain

Patent number: 9599092Abstract: A system for generating wind energy or wind power through multiple wind turbines. Each wind turbine can be smaller than a single conventional wind turbine. A series of wind turbines are mechanically connected by a chain, cable, or similar mechanical linkage to each other and to a single generator, which is located elsewhere (i.e., not in the nacelle or on the turbine tower). This permits the size and weight of each turbine to be reduced, resulting in the ability to generate electricity at lower wind speeds (e.g., where the wind speed is below the cut-in wind speed of 4 m/s or 9 mph for conventional wind turbines). The reduction in size and weight also reduces the inertia of each turbine, increasing its efficiency.Type: GrantFiled: June 19, 2014Date of Patent: March 21, 2017Inventors: Md Maruf Hossain, Mohd Hasan Ali

Patent number: 8470459Abstract: The present invention describes processes for coating substrates with a nanocomposite SiCON material. In addition, the present invention describes the dielectric nanocomposite coatings.Type: GrantFiled: March 25, 2009Date of Patent: June 25, 2013Assignee: The Curators of the University of MissouriInventors: Shubhra Gangopadhyay, Maruf Hossain, Keshab Gangapadhyay

Patent number: 8066831Abstract: A method of generating power uses a nanoenergetic material. The nanoenergetic material comprising thermite is obtained and deposited on a substrate. An igniter is placed on the nanoenergetic material. When power is desired, the nanoenergetic material is ignited. A transducer receives thermal, sonic, magnetic, optic and/or mechanical energy from combustion of the nanoenergetic material and converts it into electrical energy. Preferably, the transducer is a thermoelectric, piezoelectric or magneto device. Preferably, multiple transducers are integrated in one power generators to maximize the power from nanoenergetic thermites.Type: GrantFiled: October 27, 2006Date of Patent: November 29, 2011Assignee: The Curators of the University of MissouriInventors: Shubhra Gangopadhyay, Steven Apperson, Keshab Gangopadhyay, Andrey Bezmelnitsyn, Rajagopalan Thiruvengadathan, Michael Kraus, Rajesh Shende, Maruf Hossain, Senthil Subramanian, Shantanu Bhattacharya, Yuangang Gao

Patent number: 7879721Abstract: The present process for rapidly heating and cooling a target material without damaging the substrate upon which it has been deposited. More specifically, target material is coated onto a first substrate. A self-propagating nanoenergetic material is selected that combusts at temperatures sufficient to change the target material and creates a flame front that propagates sufficiently quickly that the first substrate is not substantially heated. The nanoenergetic material is deposited on the target material, such that the target material and the nanoenergetic material is sandwiched between the substrate and the target material. The nanoenergetic material is ignited and the flame front of the nanoenergetic material is allowed to propagate over the second substrate and change the target material.Type: GrantFiled: October 27, 2006Date of Patent: February 1, 2011Assignee: The Curators of the University of MissouriInventors: Shubhra Gangopadhyay, Maruf Hossain, Keshab Gangopadhyay, Rajesh Shende
