Patent number: 9951599Abstract: Methods and apparatuses for determining surface wetting of a metallic material with changing well fluids. In general, the methods according to the invention include measuring electrical impedance spectroscopy (“EIS”) for a system simulating downhole conditions for the wetting of a surface. Methods and apparatuses for making EIS measurements model double-layer capacitance at a downhole surface in a well, from which the nature and quantification of the wetting of the surface can be inferred.Type: GrantFiled: October 26, 2015Date of Patent: April 24, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Sairam KS Pindiprolu, Dennis Willie Gray, Venkata Gopala Rao Palla

Patent number: 9724659Abstract: A stirring device and method for stirring a material using an applicator with an electrically controllable element placed on an outside surface of the applicator so that a controllable power source coupled to the electrically controllable element provides a controlled electrostatic charge to the element. The controlled electrostatic charge provided by the power source creates a variable electric field exterior to the outside surface of the applicator. The variable electric field induces a stirring movement to the material.Type: GrantFiled: December 18, 2014Date of Patent: August 8, 2017Assignee: Flextronics AP, LLCInventors: Susan Abraham, Dennis Willie

Patent number: 9609738Abstract: A formed graphite sheet is shaped and sized as a protective shield positioned over an electronic component coupled to a PCB. The formed graphite sheet is used to protect a body of the electronic component from heat applied during the assembly of the electronic component to the PCB, such as the heating steps used in SMT and through-hole technology. The formed graphite sheet is shaped to selective direct impinging heat. The heat can be directly away from the entire electronic component. Alternatively, the heat can be selectively directed away from some portions of the electronic component and toward other portions of the electronic component.Type: GrantFiled: December 4, 2014Date of Patent: March 28, 2017Assignee: Flextronics AP, LLCInventors: Dennis Willie, Richard Loi, David Geiger, Anwar Mohammed, Murad Kurwa, Hector Rene Marin Hernandez

Patent number: 9566764Abstract: Two substrates are mechanically and electrically coupled together using a combination of a fast cure electrically non-conductive epoxy for mechanical attachment and a slow cure electrically conductive epoxy for electrical interconnects. The two epoxies are selectively applied between the two substrates as a stack, and the stack is subjected to a temperature that is sufficient to cure the fast cure electrically non-conductive epoxy in a short period of time but does not damage the substrates or components coupled thereto. In some applications, the temperature is less than 100 degrees Celsius and the time period is less than 5 seconds. The stack is removed from the heat and the slow cure electrically conductive epoxy continues to cure over a longer second period of time, such as a few hours to a day.Type: GrantFiled: December 22, 2014Date of Patent: February 14, 2017Assignee: Flextronics AP, LLCInventors: Anwar Mohammed, Weifeng Liu, David Geiger, Dennis Willie, Gervasio Mutarelli, Murad Kurwa

Patent number: 9560897Abstract: A test apparatus and method for testing a shoe comprises a base, with a shoe fixture for fixing a shoe against displacement, and an actuator, including a shoe contactor, mounted to the movable portion of the actuator connected to the base so that a shoe fixed to the shoe fixture can be placed in alternating stress conditions. The movable portion of the actuator is displaceable between a first position in which the shoe contactor is positioned away from the shoe fixture and a second position in which the shoe contactor is positioned proximate to the shoe fixture to contact and deflect the shoe.Type: GrantFiled: December 19, 2014Date of Patent: February 7, 2017Assignee: Flextronics AP, LLCInventors: Cat Le, Dennis Willie

Publication number: 20160318092Abstract: Described are embodiments of a portable crimping device for creating frame assemblies. The device includes in embodiments a rod that is movable from a first position to a second position. A head is connected to the rod, and a stud is connected to the head. When the rod is moved from the first position to the second position the stud engages a rail of a frame and deforms a portion of the rail, which secures a bracket in a channel of the rail. A second rail can then be secured to a second side of the bracket in a similar way to create a corner of a frame. The process can be repeated to generate an enclosed frame assembly for holding items such as photovoltaic panels.Type: ApplicationFiled: April 29, 2016Publication date: November 3, 2016Inventors: Dave Messick, Dennis Willie

Patent number: 8347693Abstract: Disclosed is a fluid testing device which utilizes a small, cross-section fluid interface to separate a test fluid chamber from a drive and measuring chamber. The test fluid chamber contains the test fluid and a paddle-type fluid test assembly. The drive and measuring chamber contains a second fluid and assemblies for moving the paddle and for determining the resistance movement. The two chambers are connected together by a narrow cross-section passageway allowing for continuous testing while test fluids are flowed through the test chamber and for successive testing of different samples without breaking down the device between tests. A pair of coaxial shafts extends between the test fluid chamber and the drive and measuring chamber. The shafts are connected together by a spring located in the drive chamber whereby the resistance to movement is determined by measuring the deflection in the spring. The shafts are magnetically coupled to a motor to rotate the shafts.Type: GrantFiled: August 26, 2010Date of Patent: January 8, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Sairam K S Pindiprolu, Dennis Willie Gray, Christopher Lynn Gordon, Balasundaram Balaraman
