Publication number: 20210246755Abstract: A harsh environment integrated MPD riser joint includes a dynamic annular sealing system, a static annular sealing system disposed directly below the dynamic annular sealing system, and a flow spool, or equivalent thereof, disposed directly below the static annular sealing system. The dynamic annular sealing system may be a conventional ACD-type, RCD-type, or other conventional annular sealing system. The static annular sealing system may include one or more annular packer systems and one or more connection sealing elements that engage drill pipe during connection or non-rotation operations only. The dynamic annular sealing system may maintain annular pressure during drilling operations while the static annular sealing system is disengaged. The static annular sealing system may maintain annular pressure during connection operations while the dynamic annular sealing system is disengaged.Type: ApplicationFiled: April 29, 2021Publication date: August 12, 2021Inventors: Austin Johnson, Justin Fraczek

Publication number: 20210230963Abstract: An integrated managed pressure drilling (“MPD”) riser joint includes an annular sealing system that allows for the installation, engagement, service, maintenance, disengagement, removal, or replacement of one or more sealing elements while maintaining a pressure tight seal on the annulus without a drill string isolation tool, or equivalent thereof. The integrated MPD riser joint is limited to the annular sealing system and a flow spool, or equivalent thereof, disposed directly below the annular sealing system, without any intervening pressure containment devices or systems. Advantageously, the integrated MPD riser joint does not require a drill string isolation tool, or equivalent thereof, and may be substantially shorter in length and weigh substantially less than a conventional integrated MPD riser joint. The reduction in size and weight enables adoption of MPD technology in applications where conventional integrated MPD riser joints are not economically feasible or are otherwise precluded from use.Type: ApplicationFiled: April 16, 2021Publication date: July 29, 2021Inventors: Austin Johnson, Justin Fraczek, Robert H. J. Pinkstone

Patent number: 11053768Abstract: A seal assembly for use in a pressure containment device for containing a fluid pressure in an annular space around a drill string whilst allowing the drill string to rotate in the pressure containment device. The seal assembly includes a seal with an inner surface and a tubular body, and a wear sensor embedded in the tubular body of the seal. The wear sensor emits an alert signal when the inner surface of the seal has been worn away by a first preset amount. The alert signal includes a pressure signal and/or a chemical signal.Type: GrantFiled: December 3, 2018Date of Patent: July 6, 2021Assignee: MANAGED PRESSURE OPERATIONS PTE. LTDInventors: Christian Leuchtenberg, Austin Johnson, Patrick David Savage

Publication number: 20210153498Abstract: An improved packaging assembly for storing, distributing, treating, mixing, and dispensing tissue and/or cellular material and/or implantable material. The packaging assembly may include pouches, tubes, and a bag made of a sealable, flexible polymeric material that is open at one end and a needle-free swabable connector attached to the pouch at the other end and acting as a port to allow for the introduction or discharge of biological solutions, rinsing solution, and/or preservation solutions into the packaging assembly. The designed thickness of the wall of the packaging assembly facilitates efficient heat/cold transfer, which is useful for successful controlled rate freezing, quick thawing, and resuscitation of viable cells or tissue. The packaging assembly is also useful for combining additional biological fluids with the cellular material or tissue, and for efficient mixing of the biological fluids with the tissue and/or cellular material in the assembly.Type: ApplicationFiled: January 6, 2021Publication date: May 27, 2021Inventors: Silvia Chen, Austin Johnson, Roberto Bracone

Patent number: 10971500Abstract: A method used in fabrication of integrated circuitry comprises forming metal material outwardly of a substrate. At least a majority (i.e., up to and including 100%) of the metal material contains ruthenium in at least one of elemental-form, metal compound-form, or alloy-form. A masking material is formed outwardly of the ruthenium-containing metal material. The masking material comprises at least one of nine specifically enumerated materials or category of materials. The masking material is used as a mask while etching through an exposed portion of the ruthenium-containing metal material to form a feature of integrated circuitry that comprises the ruthenium-containing metal material.Type: GrantFiled: June 6, 2019Date of Patent: April 6, 2021Assignee: Micron Technology, Inc.Inventors: Ying Rui, Tong Liu, Yi Fang Lee, Davide Colombo, Silvia Borsari, Austin Johnson

Publication number: 20200300052Abstract: A method of seal condition monitoring may determine the state of the annular seal, the state of one or more sealing elements, take actions to maintain the annular seal as one or more sealing elements transition from new to worn, and provide advance notice of the impending failure of one or more sealing elements so as to avoid a catastrophic annular seal failure while the marine riser is pressurized. Advantageously, operations may be conducted proactively rather than reactively, and one or more sealing elements may be replaced well in advance of failure, but potentially later than a conventional maintenance schedule would dictate. The one or more failing sealing elements may be proactively replaced without depressurizing the marine riser, prior to seal failure or replacement may be planned well in advance and coordinated with other rig operations to improve efficiency and maintain the safety of the drilling rig and personnel.Type: ApplicationFiled: June 9, 2020Publication date: September 24, 2020Inventors: Austin Johnson, Justin Fraczek, Waybourn Anderson, JR., Brian Piccolo, Saravanan Sundaramoorthy, Alexander John MacGregor, Kareem Ahmed Ameen Amer, George James Michaud

Publication number: 20200054520Abstract: Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user.Type: ApplicationFiled: November 10, 2017Publication date: February 20, 2020Inventors: Michael Austin Johnson, Jason Adams, Jean-Pierre Delplanque, Justin Koos, Gregory Rehm
