Patent number: 11927076Abstract: A method of reducing condensate accumulation in a natural gas well may include a first step of determining a pressure and a temperature of the natural gas well. The method may further include a second step of determining a dew point temperature based on the pressure of the natural gas well. The method may also include a third step of determining a cricondentherm temperature of the natural gas well. The method may also include a fourth step of heating the natural gas well to a temperature above the dew point temperature; and a fifth step of limiting the temperature of the natural gas well to the cricondentherm temperature.Type: GrantFiled: July 19, 2022Date of Patent: March 12, 2024Assignee: Salamander IP Holdings LLCInventors: John Michael Karanikas, Robert Guy Harley, Guillermo Pastor

Patent number: 6644137Abstract: A sampling probe includes a housing, a cover and a guide. The housing defines a trough having an opening, at least a portion of the opening being in an insertion direction of the probe. The cover is axially movable with respect to the housing between an open position in which a substance is allowed to pass into the trough and a closed position in which the cover covers the opening to retain a predetermined volume of the substance in the trough. The cover is flexible. The guide is configured to guide axial movement of the cover between the open and closed positions. The guide is configured to direct the cover in a curved path.Type: GrantFiled: June 14, 2000Date of Patent: November 11, 2003Assignee: University of Puerto RicoInventors: Michael Bellamy, Robert Pastor, Norman Mortensen

Patent number: 5941919Abstract: In a vehicle with a first operating mode in which all vehicle wheels have substantially no lateral movement on a road surface and a second operating mode in which at least some of the vehicle wheels have lateral movement on the road surface, and with an actuator capable of affecting vehicle yaw rate, a vehicle yaw rate control method comprising the steps of: measuring an actual vehicle yaw rate; measuring vehicle steering wheel position; in the second mode of operation, determining a desired yaw rate command linearly responsive to the measured steering wheel position; wherein the actuator is controlled to minimize a difference between the measured vehicle yaw rate and the desired vehicle yaw rate.Type: GrantFiled: October 16, 1996Date of Patent: August 24, 1999Assignee: General Motors CorporationInventors: Stephen Robert Pastor, Ronald Paul, Michael Douglas Rizzo, Edward John Bedner, Vivek Jaikamal, Kevin Austin O'Dea, Edmund Stanley Browalski, Howard Hans Ludwig, Scott Douglas Morrison, Hsien Heng Chen, Yuen-Kwok Chin, Youssef Ahmed Ghoneim, William Chin-Woei Lin, Mutasim Abdurrahman Salman, David Michael Sidlosky, Michael Paul Turski

Patent number: 5857160Abstract: A sensor-responsive control method for use on a motor vehicle, comprising the steps of: measuring a vehicle yaw rate; measuring a vehicle lateral acceleration; responsive to the measured yaw rate and lateral acceleration, estimating a steering wheel angle; determining an error signal responsive to the difference between the estimated steering wheel angle and an adaptive steering position signal; and updating the adaptive steering position signal responsive to the error signal, wherein the adaptive steering position signal is quickly determined after the vehicle begins to move.Type: GrantFiled: May 23, 1996Date of Patent: January 5, 1999Assignee: General Motors CorporationInventors: John E. Dickinson, Douglass L. Carson, Mutasim Abdurrahman Salman, Stephen Robert Pastor, Gordon Leo Tierney, Hong Xing Hu, Todd Brown, Alan James Lee, Eldon Gerrald Leaphart

Patent number: 5746486Abstract: A brake control system method according to the steps of: determining driver commanded yaw rate; measuring actual yaw rate; determining a yaw rate error; determining, in response to vehicle conditions, a yaw rate dead band wherein the yaw rate dead band varies with vehicle conditions; comparing the yaw rate error to the dead band; and if the yaw rate error exceeds the dead band, controlling the vehicle responsive to the yaw rate error, wherein yaw rate control only occurs when the yaw rate error exceeds the dead band.Type: GrantFiled: August 29, 1997Date of Patent: May 5, 1998Assignee: General Motors CorporationInventors: Ronald Paul, Stephen Robert Pastor, Michael Douglas Rizzo, Duane Edward Bassett, Edward John Bedner, Douglass L. Carson, Hsien Heng Chen, Yuen-Kwok Chin, Youssef Ahmed Ghoneim, Alan James Lee, William Chin-Woei Lin, Howard Hans Ludwig

Patent number: 5720533Abstract: In a vehicle with first and second front vehicle wheels and third and fourth rear vehicle wheels and at least one member of a first group comprising anti-lock brake control and positive acceleration traction control, a brake control method comprising the steps of: determining a desired vehicle yaw rate; determining an actual vehicle yaw rate; responsive to the desired and actual vehicle yaw rates, determining an axle command; responsive to the desired and actual vehicle yaw rates, determining a torque command; applying the axle command during activation of one of the anti-lock brake control and the positive acceleration traction control to one member of a second group comprising (i) the two front wheels and (ii) the two rear wheels, wherein wheel-to-road traction is increased and a difference between desired vehicle yaw rate and actual vehicle yaw rate is minimized; and applying the torque command to at least one of the vehicle wheels independently of the axle command to create a yaw torque moment on the vehiType: GrantFiled: October 15, 1996Date of Patent: February 24, 1998Assignee: General Motors CorporationInventors: Stephen Robert Pastor, William Chin-Woei Lin, Michael Douglas Rizzo, Duane Edward Bassett, Edward John Bedner, Edmund Stanley Browalski, Douglass L. Carson, Hsien Heng Chen, Yuen-Kwok Chin, Youssef Ahmed Ghoneim, Hong Xing Hu, Vivek Jaikamal, Ronald Paul, Steven Lee Tracht, Michael Paul Turski
