Patent number: 11306190Abstract: A method for modifying a polymeric surface is disclosed. The polymeric surface is activated utilizing atmospheric pressure plasma. An atom transfer radical polymerization initiator is then coupled to the activated surface. A monomer is then polymerized on the activated surface utilizing an activators regenerated by electron transfer (ARGET) atom transfer radical polymerization (ATRP) process. The method enables brush-modification of the polymeric surface, even if the polymeric surface is substantially chemically inert. By way of example, the method enables a chemically inert, substantially hydrophobic polymer surface to be functionalized with substantially hydrophilic polymer brushes. The methods of the present disclosure have general applicability to a myriad of implementations where tunable surface chemistry is advantageous, such as filtration membranes, marine surfaces, and medical devices seeking a biocompatible coating.Type: GrantFiled: September 8, 2017Date of Patent: April 19, 2022Assignee: Rensselaer Polytechnic InstituteInventors: John Joseph Keating, Georges Belfort, Istvan Zsolt Kocsis, Mirco Sorci, Alexander Kenneth Lee

Publication number: 20210237002Abstract: Functionalized membranes are produced via grafting of polymer brushes to the membrane surface for use, e.g., in separation and purification of biomolecules. One or more initiators are attached to the membrane surface. A reactant substrate, such as a copper metal plate, is placed adjacent the membrane. A reaction medium is then provided in fluid contact with the membrane and the reactant substrate, the reaction medium including one or more monomers, one or more ligands, and one or more solvents. The polymer brushes are grown on the membrane via Cu(0)-mediated controlled radical polymerization involving the reactant substrate and the reaction medium. This reaction process uses fewer numbers and amounts of chemicals compared to other controlled radical polymerization reactions such as ATRP. The reaction can take place at room temperature, which is more energy efficient than other CRPs which occur at a much higher temperatures.Type: ApplicationFiled: June 5, 2019Publication date: August 5, 2021Applicant: RENSSELAER POLYTECHNIC INSTITUTEInventors: Somdatta Bhattacharya, John Joseph Keating, Georges Belfort

Patent number: 9851407Abstract: The invention relates to a power management system for supplying backup DC power to peak and/or high current demand battery applications, such as motor starting or an uninterruptible power supply (UPS) used to power a critical load, such as, a data bus or other critical load, after an event, such as loss of primary AC or DC input, during relatively cold ambient temperatures. Two or more heaters can be provided; for example, a low power heater and a high-power heater. In a maintenance mode, the low power heater is used to maintain batteries at a predetermined temperature. In this mode, a battery charger is used to power the low power heater. In a boost mode, after the primary AC or DC input is restored, and battery temperature is too low to back up the critical load, the battery charger supplies power to one or both of the heaters.Type: GrantFiled: May 4, 2015Date of Patent: December 26, 2017Assignee: ICC-NEXERGY, INC.Inventors: Joseph Keating, I, Chris Turner, Robert F.

Publication number: 20150377971Abstract: A power management system is disclosed for providing an indication of the required available capacity (RAC) available from a backup battery unit (BBU) for backup or peak loading as required by a critical DC load, such as a computer bus. The power management system is configured to repeatedly determine the gross remaining capacity of the backup battery unit (BBU). The system processes this information and other measured or known battery parameters to determine the required available capacity (RAC). The RAC is based upon the required capacity of the critical load to which the BBU is connected. In general, the RAC is the difference between the gross remaining capacity of the battery at a given point in time and the required capacity of the critical load. In accordance with an important feature of the power management system, an indication of the RAC is provided.Type: ApplicationFiled: June 29, 2015Publication date: December 31, 2015Applicant: ICC-NEXERGY, INC.Inventors: Joseph Keating, Tai-Guang Huang, Julie JoAnn Lee, Michael Krzywosz, David Wilczewski

Publication number: 20150111431Abstract: Briefly, the present invention relates to a cigarette lighter adapter (CLA) configured to be received in a CLA socket in a vehicle. The CLA includes a positive contact and a negative contact and housing, for example, a plastic housing. The negative contacts are formed as springs, which extend from the housing and are configured to exert spring force against an interior wall of a socket to assure a solid connection. The positive contact is also formed as a spring and is connected in series with a thermal sensor. In accordance with an important aspect of the invention, the thermal sensor, for example, a bi-metallic strip, is in thermal contact with a tip, which is serially connected to the positive contact and which extends outwardly from the plastic housing, the thermal sensor causes the CLA to be disconnected from the socket when an excessive temperature is sensed.Type: ApplicationFiled: October 23, 2014Publication date: April 23, 2015Applicant: ICC-NEXERGY, INC.Inventors: ROBERT F.
