Patent number: 11913182Abstract: A force-absorbing barrier includes a plurality of chambers at least partially filled with fluid. The walls defining the chambers are flexible. Fluid passages in the interior walls between chambers allow fluid flow between the chambers. Alternatively, the chambers are filled with structures instead of or in addition to a fluid. The fluid flow from chamber to chamber and/or the deformation of the structures will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.Type: GrantFiled: August 23, 2021Date of Patent: February 27, 2024Assignee: Ohio UniversityInventors: Muhammad Ali, Sean R. Jenson, Khairul Alam

Patent number: 10799884Abstract: A fluid processing system and method of processing a fluid includes a tank having an outer wall, a heating element, and an insulating element. The heating element is situated within the tank and includes a first electrode and a second electrode. The insulating element is positioned between the first electrode and the second electrode. As such, powering the heating element directs an electric current through the fluid within the tank for heating the fluid, while the insulating element provides electrical and thermal insulation to the outer wall of the tank.Type: GrantFiled: October 15, 2015Date of Patent: October 13, 2020Assignee: Ohio UniversityInventors: Khairul Alam, Hajrudin Pasic

Patent number: 10625197Abstract: A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.Type: GrantFiled: April 21, 2016Date of Patent: April 21, 2020Assignee: Ohio UniversityInventors: Hajrudin Pasic, Khairul Alam

Patent number: 10022727Abstract: A discharge electrode with equal or better performance to conventional discharge electrodes, but at significantly lower cost uses carbon fiber composite tapes suspended around support rings attached to a support at the top and a bias at the bottom. The tape is in a loop and extends around the support rings, causing the rings to be pulled apart in tension by the bias to keep the tape taut. The tape, and preferably the top ring, and alternatively the lower ring, are conductively connected to a power supply.Type: GrantFiled: September 25, 2014Date of Patent: July 17, 2018Assignee: Ohio UniversityInventor: Khairul Alam

Patent number: 9950325Abstract: A discharge electrode using carbon fibers, nanofibers and/or nanotubes to generate the corona discharge. The invention contemplates conductive fiber, such as carbon strands with or without a polymer matrix to form a composite, and a supporting configuration in which the strand is extended along or wrapped helically around a supporting rod that extends along the length of the electrode. A mechanical bias is applied to each strand to maintain tension on the strand. Preferably this includes coil springs extending between bushings mounted on the rod and moveable hemispherical supports slidably mounted on the rod that seat against the strand.Type: GrantFiled: June 19, 2014Date of Patent: April 24, 2018Assignee: Ohio UniversityInventor: Khairul Alam
