Patent number: 11572780Abstract: Impedance is used to determine the performance of paraffin inhibitors in oil containing paraffin. The method and system can use a specially designed impedance cell having a cell constant of less than 1 cm?1. Further, the method can include obtaining at least impedance measurements above the wax appearance temperature (WAT) for an oil sample treated with a paraffin inhibitor and an oil sample not treated, and impedance measurements below the WAT for the treated oil sample and the untreated oil sample. Thereafter, the impedance measurements are correlated to determine paraffin inhibitor performance.Type: GrantFiled: April 27, 2020Date of Patent: February 7, 2023Assignee: The University of TulsaInventors: Marc Tappert, Dale Teeters

Patent number: 11031581Abstract: A process of sputter deposition of both a cathode material and an anode material from a single target source. The process includes the steps of deposition sputtering on a porous substrate from a lithiated metal oxide target source to produce an anode. In addition, deposition sputtering on a porous substrate from the same lithiated metal oxide target source is utilized to produce a cathode. A nanostructured battery may be produced having a metal oxide anode and a lithiated metal oxide cathode, wherein the anode and the cathode are generated from a single target source.Type: GrantFiled: February 1, 2019Date of Patent: June 8, 2021Assignee: The University of TulsaInventors: Mark Poyner, Dale Teeters

Patent number: 9293759Abstract: A three-dimensional nanobattery formed by individually wiring nanostructured electrodes and combining them with an electrolyte. Short, capped nanotubes termed ‘nanobaskets’ are formed by sputtering coating onto nanoporous templates. Metallic nanowires are grown by electrochemical deposition from the nanobaskets and through the template, making electrical contact with each nanobasket electrode. The same procedure can be used to fabricate both a battery anode and a battery cathode. A thin layer of electrolyte is placed between the two nanobasket electrodes, and electrical contact is made through the nanowires.Type: GrantFiled: November 4, 2013Date of Patent: March 22, 2016Assignee: The University of TulsaInventors: Dale Teeters, Paige Johnson

Patent number: 7736724Abstract: A method of producing a nanobasket and the applications or uses thereof. The method includes the steps of providing a substrate with at least one (1) pore having diameters of about one (1) nanometer to about ten (10) micrometers. Material is deposited by sputter-coating techniques along continuous edges of the pores to form a capped or partially capped nanotube or microtube structure, termed a nanobasket. Either a single material may be used to form nanobaskets over the pores or, alternately, a layered structure may be created wherein an initial material is deposited followed by one or more other materials to form nanobaskets over the pores.Type: GrantFiled: May 12, 2006Date of Patent: June 15, 2010Assignee: The University of TulsaInventors: Paige Lea Johnson, Dale Teeters

Patent number: 6776056Abstract: A seat belt tension sensor for measuring the magnitude of tension in a seat belt. The seat belt tension sensor has a housing with a cavity. An anchor plate has a portion located in the cavity. The housing moves relative to the anchor plate between a first position and a second position. A sensor is mounted to the housing. The housing presses on the sensor as the housing moves from the first to the second position. The sensor generates an electrical signal in response to the housing moving between the first and second positions. The electrical signal changes as a function of tension on the seat belt. The sensor is a strain gage. The housing engages the anchor plate in the second position to protect the sensor from damage in a vehicle crash situation.Type: GrantFiled: June 28, 2002Date of Patent: August 17, 2004Assignee: CTS CorporationInventors: Ryan Garver, Murray Kaijala, Dale Teeters
