Patent number: 11914402Abstract: The present disclosure generally relates to dynamic power curve throttling. In an exemplary embodiment, a computer-implemented method for enabling dynamic throttling of an engine includes graphically displaying a graph of a linear throttle line for the engine including an idle speed in revolutions per minute (RPM) and one or more operating speeds in revolutions per minute; using a graphical user interface to alter the linear throttling line into a non-linear dynamic throttling line; and generating a table based on the non-linear dynamic throttling line, the table including dynamic throttle increments that vary based on RPM and that are usable by a controller for dynamic throttling of the engine.Type: GrantFiled: October 15, 2021Date of Patent: February 27, 2024Assignee: Cattron North America, Inc.Inventors: Brett Allen Davis, James Leighton Staggs, John Edward Geertsema, Jr.

Patent number: 11814920Abstract: A technique facilitates patching of a tubing (42), e.g. casing (36), in a downhole environment (32). The technique employs a patching system comprising a plurality of expansion rings (48). The expansion rings (48) are moved downhole to a patch zone (38) along the tubing (34). Once in a desired position at the patch zone, the expansion rings (48) are expanded into engagement with an inner surface of the tubing. For example, the expansion rings may comprise seal elements (52) and/or anchor elements which are expanded into engagement with the inside surface. The patching system further comprises a patch (68) which may have a tubular shape. The patch is radially expanded in a manner which maintains a sealing engagement with the plurality of expansion rings (48) to create a sealed patch across a desired region in the patch zone.Type: GrantFiled: January 21, 2020Date of Patent: November 14, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Samuel Roselier, James Leighton, Benjamin Saltel, Robin McGowan, Juan Miguel La Rotta Marin, Gareth Brown

Patent number: 11668930Abstract: Optical hyperfocal reflective systems and methods are provided. One such optical hyperfocal reflective system has an optical substrate; an optical input coupling portion configured to input couple a collimated display image to the optical substrate; and an optical hyperfocal output coupling portion integrated with said optical substrate. The optical output coupling portion includes at least one hyperfocal reflective view port formed from a discrete optical hyperfocal reflector spot integrated with the optical substrate. The discrete optical hyperfocal reflector spot is sized to form a reflected discrete optical spot beam with a diameter at a target area such that a view of a discrete virtual display image portion, as seen by a lens-detector system locatable at the target area, is hyperfocused.Type: GrantFiled: July 12, 2021Date of Patent: June 6, 2023Assignee: Meta Platforms Technologies, LLCInventors: Brennon Pennell, James Leighton, Adrian Stannard, Louahab Noui, Iain Wright, Lawrence Hoar

Publication number: 20230161163Abstract: Optical devices and methods for expanding input light and outputting the expanded light include a waveguide and an input optical element to receive light incident on a first side of the waveguide. The input optical element includes an input reflective surface to reflect the received light into the waveguide. An intermediate diffractive optical element receives light in the waveguide from a first direction, and provides an expansion of the received light in a second direction perpendicular to the first direction. An output optical element includes an output reflective surface to reflect the expanded light out of the waveguide towards a viewer. The waveguide guides light along an optical path from the input optical element to the intermediate diffractive optical element and from the intermediate diffractive optical element to the output optical element.Type: ApplicationFiled: April 7, 2021Publication date: May 25, 2023Inventor: James Leighton

Publication number: 20230152536Abstract: Optical devices and methods include a first waveguide having a first surface and a second waveguide including a second surface. The first waveguide is at a fixed position relative to the second waveguide with the first surface at least partly facing the second surface, and the first surface includes a first positioning element. The first positioning element is a NanoImprint Lithography (NIL) structure. The optical device further includes an adhesive arranged for attaching the first surface to the second surface, whereiu the first positioning element is arranged to control a position of the adhesive. The first positioning element includes a philic region adapted to attract the adhesive, or a phobic region adapted to repel the adhesive.Type: ApplicationFiled: April 7, 2021Publication date: May 18, 2023Inventor: James Leighton
