Patent number: 11971056Abstract: A head unit device for controlling motion of an object includes a chamber filled with a shear thickening fluid (STF) and a piston. The piston is housed within the chamber and exerts pressure against the STF from a force applied to the piston from the object. The STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates. The piston includes at least one piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston to selectively react with a shear threshold effect of the first range of shear rates or the second range of shear rates.Type: GrantFiled: October 29, 2021Date of Patent: April 30, 2024Assignee: Moshun, LLCInventors: Timothy John Boundy, Steven Michael Barger, Terence Michael Lydon, Richard Michael Lang, Wilfredo Gonzalez, Jr., Darren Michael Boundy, Eric McHugh, David Schuda, George L Wilson, IV, Gary W.

Patent number: 10053961Abstract: A method and apparatus for removing debris from a wellbore using a cleaning tool. The tool may comprise an inner mandrel and a cup member coupled to the inner mandrel. The cup member is moveable between a collapsed position where fluid may flow across the exterior of the cup member, and an extended position where fluid is diverted into a flow path disposed between the inner mandrel and the cup member. The fluid is diverted through a filter member that is coupled to the inner mandrel below the cup member.Type: GrantFiled: September 15, 2014Date of Patent: August 21, 2018Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Timothy L.

Patent number: 9382769Abstract: A method of drilling a wellbore includes drilling the wellbore by injecting drilling fluid through a drill string extending into the wellbore from surface and rotating a drill bit of the drill string. The drill string further includes a circulation sub having a port closed during drilling. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to the surface via an annulus formed between an outer surface of the tubular string and an inner surface of the wellbore. The method further includes after drilling at least a portion of the wellbore: halting drilling; sending a wireless instruction signal from the surface to a downhole portion of the drill string by articulating the drill string, acoustic signal, or mud pulse, thereby opening the port; and injecting drilling fluid through the drill string and into the annulus via the open port.Type: GrantFiled: January 23, 2012Date of Patent: July 5, 2016Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Timothy L.

Patent number: 9328579Abstract: A method and apparatus for circulating fluid in a wellbore includes a bottom sub having a bottom sub port and a mandrel, wherein the mandrel substantially forms an inner bore of the circulating tool and includes a mandrel port. The circulating tool may also include an activation piston that is movable in a first direction and a port piston movable in a second direction when the activation piston moves in the first direction. The circulating tool may further include an inner sleeve coupled to the port piston and movable with the port piston, the inner sleeve having an inner sleeve port in selective communication with the mandrel port. When the inner sleeve port is in communication with the mandrel port at least partially, circulating fluid is allowed to flow through the bottom sub port to the wellbore.Type: GrantFiled: July 13, 2012Date of Patent: May 3, 2016Assignee: Weatherford Technology Holdings, LLCInventor: Timothy L.

Patent number: 7258171Abstract: A holding member provides for releasably positioning a rotating control head assembly in a subsea housing. The holding member engages an internal formation in the subsea housing to resist movement of the rotating control head assembly relative to the subsea housing. The rotating control head assembly is sealed with the subsea housing when the holding member engages the internal formation. An extendible portion of the holding member assembly extrudes an elastomer between an upper portion and a lower portion of the internal housing to seal the rotating control head assembly with the subsea housing. Pressure relief mechanisms release excess pressure in the subsea housing and a pressure compensation mechanism pressurize bearings in the bearing assembly at a predetermined pressure.Type: GrantFiled: November 21, 2005Date of Patent: August 21, 2007Assignee: Weatherford/Lamb, Inc.Inventors: Darryl A.

Patent number: 6135217Abstract: A jar up, bump down hydraulic drilling jar is described. A hydraulic tripping valve arrangement permits the storage of large amounts of static force before releasing a hammer to strike an anvil surface with substantial force. The hammer is positioned on the mandrel and interacts with the anvil surface in the housing to deliver upward jarring forces, to the drill string. During a downward jarring movement, the tripping valve is opened to prevent pressure buildup and accidental downward jarring; thus, a single-acting drilling jar is formed.Type: GrantFiled: January 19, 1999Date of Patent: October 24, 2000Inventor: Timothy L.

Patent number: 6076606Abstract: The present invention, in certain embodiments, discloses a whipstock system which is hydraulically settable in a tubular or wellbore and mechanically retrievable. In one aspect it is a "through-tubing" system. In certain aspects systems according to this invention have a concave to a lower end of which is secured an anchor housing bendable member, movable connection, or with an anchor body therein that is in fluid communication, via a flexible hose within the anchor housing, with a fluid channel running through the concave. An upper end of a mandrel is housed in a recess in the anchor body. The mandrel's lower end may extend out from the anchor housing. A setting slip is disposed below the anchor body within an opening in the anchor housing. A pusher sleeve below the slip is selectively displaced up by a piston below the pusher sleeve to push the slip out from the opening in the anchor housing to set against an interior of a tubular or of a wellbore. Fluid under pressure flows, e.g.Type: GrantFiled: September 10, 1998Date of Patent: June 20, 2000Assignee: Weatherford/Lamb, Inc.Inventors: Thomas F. Bailey, Timothy L. Wilson, Dustin G. Howell

Patent number: 5696938Abstract: A computer system is disclosed that permits multiple write buffer read-arounds. The system comprises a CPU (Central Processing Unit) for executing cycles for the computer system, a cache coupled to the CPU for storing data, a write buffer coupled to the CPU for receiving write data from the CPU, an arbiter to control bus accesses to the slave, and processing signals coupled between the cache and the write buffer for permitting the CPU to read-around the write buffer a plurality of times before the write data in the write buffer is flushed therefrom. The processing signals determine when the data stored in the write buffer is also stored in the cache, and, therefore, the cache is permitted to read-around the write buffer more than one time as long as the write buffer has the same data stored therein as exists in the cache.Type: GrantFiled: July 31, 1996Date of Patent: December 9, 1997Assignee: VLSI Technology, Inc.Inventors: David K. Cassetti, Timothy L. Wilson

Patent number: 5345495Abstract: A telephone includes means for switching the LEDs, on the face of the phone, between a normal operating mode in which the lights indicate the status of telephony features, such as mute or hold, to a diagnostic operating mode in which the LEDs indicate the status of the telephone's data communications signals. The modes are toggled by entry of a code on the telephone keypad or by way of a command from a workstation coupled to the telephone by way of a data communications port.Type: GrantFiled: August 28, 1992Date of Patent: September 6, 1994Assignee: ROLM CompanyInventors: David C.
