Patent number: 11964692Abstract: A vehicle hitching assistance system includes a controller executing an initial alignment process including searching for a trailer within a specified area of image data that is less than a total field of the image data in directions corresponding with both a longitudinal distance between the vehicle and the trailer and a lateral direction perpendicular to the longitudinal distance, presenting an indication to a driver of the vehicle to reposition the vehicle when the trailer is not identified within the specified area, and removing the indication when the trailer is identified within the specified area. The controller further executes an automated backing process upon identifying the trailer within the specified area, including identifying a coupler of the trailer and outputting a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler of the trailer during reversing.Type: GrantFiled: September 22, 2022Date of Patent: April 23, 2024Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Luke Niewiadomski, Douglas Rogan, Shannon Brooks-Lehnert, Chen Zhang, Roger Arnold Trombley, Peter Ling, Kenneth Michael Mayer, Seyed Armin Raeis Hosseiny, Bo Bao, Steven Wayne Friedlander

Patent number: 11923183Abstract: Dynamic skimmer pulsing and dynamic equilibration times are used for MS and MS/MS scans. A target percentage transmission of the ion beam is calculated based on a previous percentage transmission and a previous TIC or a previous highest intensity of a previous cycle time. An equilibration time is calculated based on the current percentage transmission and the target percentage transmission. A skimmer of a tandem mass spectrometer is controlled to attenuate the ion beam to the target percentage transmission to prevent saturation of a detector of the tandem mass spectrometer and to increase the dynamic range of the tandem mass spectrometer. The tandem mass spectrometer is controlled to perform an MS scan or an MS/MS scan after the calculated equilibration time to reduce the cycle time.Type: GrantFiled: April 14, 2022Date of Patent: March 5, 2024Inventors: Douglas Arnold Simmons, Nic G. Bloomfield

Patent number: 9977683Abstract: In one embodiment, a first thread of execution on a computing device receives a user-interface input. The first thread of execution is associated with a user interface of the computing device. The first thread of execution identifies a second thread of execution on the computing device to process the user-interface input. The second thread of execution is associated with the user interface and is de-coupled from the first thread of execution. The first thread of execution sends the user-interface input to the second thread of execution. The second thread of execution also processes the user-interface input to generate a user-interface output associated with the user-interface input.Type: GrantFiled: December 14, 2012Date of Patent: May 22, 2018Assignee: Facebook, Inc.Inventor: Robert Douglas Arnold
