Patent number: 11891038Abstract: A method for finding an optimum trailer gain, comprising: applying trailer brake pulses to a trailer while a vehicle is coasting using a trailer brake of a trailer, wherein the trailer is coupled to the vehicle; monitoring an average deceleration of the vehicle and the trailer brake gain of the trailer brake pulses applied to the trailer while the vehicle is coasting; generating a graph of the average deceleration of the vehicle versus the trailer brake gain, wherein the graph includes a curve that illustrates a relationship between the average deceleration of the vehicle and the trailer brake gain of the trailer brake pulses applied to the trailer while the vehicle is coasting; and finding a bend point of the curve in the graph to determine an optimum trailer brake gain.Type: GrantFiled: May 27, 2021Date of Patent: February 6, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Avesta Goodarzi, Hasan Alper Hepguvendik, Patrick G.

Patent number: 11686159Abstract: A gap sub assembly for electromagnetic telemetry used in downhole drilling. The gap sub comprises a female part comprising a female mating section and a male part comprising a male mating section. The male mating section is matingly received within the female mating section and electrically isolated therefrom. One or more electrically insulating bodies secure the male part axially and torsionally relative to the female part. The electrically insulating bodies also electrically isolate the male part from the female part. The electrically insulating bodies can be installed through apertures in the female part or at least some of the electrically insulating bodies can be installed before the male mating section is inserted into the female mating section. The electrically insulating bodies can be held in place on the male mating section using a retention apparatus such as a ring, a scarf, pods or an adhesive.Type: GrantFiled: August 20, 2021Date of Patent: June 27, 2023Inventors: Luke A. Stack, Aaron W. Logan, Justin C. Logan, Mojtaba Kazemi Miraki, Patrick R. Derkacz, Gavin Gaw-wae Lee, Hasan Alper Hepguvendik, Daniel W. Ahmoye, Angelica J. B. Francoeur

Patent number: 11280437Abstract: One or more seals may be provided in a gap sub to prevent the ingress of drilling fluid into an insulating gap between a male member of the gap sub and a female member of the gap sub. A first seal may comprise an internal gap sub seal provided near the tip of the male member of the gap sub. A second seal may comprise an external gap sub seal provided near the tip of the female member of the gap sub. The first and second seals may comprise non-conductive materials. The first and second seals may each comprise one or more O-rings. The first and second seals may comprise one or more lips, protrusions or flanges to engage the male and/or female members of the gap sub for maintaining contact with the male and/or female members during deformation of the gap sub.Type: GrantFiled: December 22, 2017Date of Patent: March 22, 2022Assignee: Evolution Engineering Inc.Inventors: Luke A.

Publication number: 20190322317Abstract: A hitch angle module determines a hitch angle based on an input from at least one of a vehicle rear camera and a hitch angle sensor. The hitch angle is an angle between a longitudinal centerline of a trailer and a longitudinal centerline of a vehicle. A trailer load sensor measures a load on a trailer hitch of the vehicle. A trailer wheel speed sensor measures a wheel speed of the trailer. A trailer dimension module determines at least one of a width of the trailer, a mass of the trailer, a drawbar length of the trailer, a height of the trailer, and a trailer hitching length of the vehicle based on at least one of the hitch angle, the trailer load, and the trailer wheel speed. The trailer hitching length is a distance from a rear axle of the vehicle to a distal end of the trailer hitch.Type: ApplicationFiled: April 18, 2018Publication date: October 24, 2019Applicant: GM Global Technology Operations LLCInventors: Sepehr POURREZAEI KHALIGH, Hasan Alper HEPGUVENDIK, Akram M.
