Publication number: 20130330229Abstract: A method for decontaminating bioaerosol with high concentrations of bacterial, viral, spore and other airborne microorganisms or biologic contaminants in flight at high flow rates. A plasma screen created across the flow of air contaminated with airborne biologic agents renders contaminants non-culturable within milliseconds. The technology may cooperate with heating, ventilation, and air conditioning (HVAC) systems. It may be particularly beneficial in preventing bioterrorism and the spread of toxic or infectious agents, containing airborne pandemic threats such as avian flu, sterilizing spaces such as hospitals, pharmaceutical plants and manufacturing facilities, treating exhaust ventilation streams, minimizing biological environmental pollutants in industrial settings, improving general air quality, preventing sick building syndrome.Type: ApplicationFiled: March 30, 2011Publication date: December 12, 2013Applicant: Drexel UniversityInventors: Gregory Fridman, Alexander Fridman, Yurii V.

Patent number: 8603403Abstract: A reactor for reforming a hydrocarbon, and associated processes and systems, are described herein. In one example, a reactor is provided that is configured to use non-equilibrium gliding arc discharge plasma. In another example, the reactor uses a vortex flow pattern. Two stages of reforming are described. In a first stage, the hydrocarbon absorbs heat from the wall of the reactor and combusts to form carbon dioxide, carbon monoxide, and water. In a second stage, a gliding arc discharge is use to form syngas, which is a mixture of hydrogen gas and carbon monoxide. The heat generated by the combustion of the first stage transfers to the wall of the reactor and heated products of the second stage mix with incoming hydrocarbon to provide for partial recuperation of the reaction energy.Type: GrantFiled: August 30, 2012Date of Patent: December 10, 2013Assignee: Drexel UniversityInventors: Alexander F.

Publication number: 20130310731Abstract: Method for the non-thermal treatment of human or animal tissue with high-voltage electrical discharge plasma is disclosed. The disclosed method employs current through plasma and through tissue not for the purpose of heating the tissue, but instead to maintain the plasma proximate to the tissue being treated. Also disclosed is a method of limiting the current through plasma and through tissue to minimize tissue heating by placement of an insulator or semiconductor between an electrode and tissue resulting in generation of a high-voltage discharge similar to a dielectric barrier discharge. The disclosed non-thermal plasma treatment can be employed to promote coagulation of blood, sterilization, disinfection, re-connection of tissue, and treatment of tissue disorders without causing significant thermal tissue damage.Type: ApplicationFiled: July 25, 2013Publication date: November 21, 2013Applicant: DREXEL UNIVERSITYInventors: ALEXANDER F.

Patent number: 8554419Abstract: In the event that the brake pedal and accelerator pedal are depressed simultaneously, powertrain output is decreased monotonically with brake pedal input. In a lower range of brake pedal input, the brakes are prevented from actuating or are allowed to actuate minimally. In a higher range of pedal input, the powertrain output continues to be decreased and the brakes are allowed to actuate. In yet another higher range of pedal input, the powertrain output is substantially decreased such that a minimal powertrain output is achieved. The powertrain may include an internal combustion engine and/or an electric motor. The brake pedal input is determined based on a sensor associated with the brake pedal, the brake booster, or the master cylinder.Type: GrantFiled: May 28, 2010Date of Patent: October 8, 2013Assignee: Ford Global Technologies, LLCInventors: Dale Scott Crombez, Moses Alexander Fridman, Douglas Raymond Martin

Patent number: 8388618Abstract: The use of non-thermal plasma to treat mucus membrane bleeding is described herein. A non-thermal plasma is generated using an apparatus having a first electrode that receives alternating electrical potentials from a power supply. When placed in an appropriate location proximate to tissue, a non-thermal plasma is generated, the second electrode being human tissue, blood, etc. To reduce the likelihood of an arc being generated, potentially causing tissue damage or pain, the first electrode is partially encapsulated by a dielectric.

Publication number: 20120156091Abstract: Methods and devices for treating surfaces of objects using a non-thermal plasma are disclosed herein. The non-thermal plasma is generated through the use of an apparatus configured to generate a non-thermal plasma on its surface.

Publication number: 20120116656Abstract: Power brakes are typically vacuum assisted, with the vacuum provided from the intake manifold. If the engine is commanded to operate for a long period at a condition with low intake manifold vacuum, the vacuum within the brake booster may drop to a level which is marginal or insufficient for a present or subsequent braking operation. To ensure sufficient vacuum in the intake manifold to provide to the brake booster, the engine may be commanded to operate at a condition to increase intake manifold vacuum by one of: adjusting cam timing, increasing engine speed, and increasing EGR. In the case of a stop-start vehicle, the engine speed is increased from zero to a condition that provides the desired vacuum.Type: ApplicationFiled: November 8, 2010Publication date: May 10, 2012Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Douglas Raymond Martin, Dale Scott Crombez, Moses Alexander Fridman
