Publication number: 20220042632Abstract: A fluid connection apparatus, in which a carrier body and washer configuration are overmolded together, is configured for use in a fluid transfer assembly. The carrier body may be generally U-shaped, having two substantially parallel portions connected by a bridging portion. Each substantially parallel portion of the fluid connection apparatus includes a washer configuration including one or more washers. The fluid connection apparatus may be used to connect a fluid line fitting to an apparatus intended to provide or receive fluid through the fluid line, using a connector having a fluid passage formed therein. The fluid line fitting is placed between the two substantially parallel portions, and a connector having a fluid passage formed therein is inserted through one side of the fluid connection apparatus, through the fluid line fitting, and through the other side of the fluid connection apparatus.Type: ApplicationFiled: October 12, 2021Publication date: February 10, 2022Inventor: John R. Churchill

Patent number: 9897666Abstract: An optomechanical oscillator for measuring a magnetic field may include a fixed substrate, a moveable mass separated from the fixed substrate by a slot, a photonic crystal comprising an optomechanical cavity formed at the slot, and a current source operably coupled to provide current to the photonic crystal. The moveable mass may be moveable responsive to placement of the optomechanical oscillator in a magnetic field based on interaction of the magnetic field and the current. The magnetic field may be measureable based on displacement of the moveable mass.Type: GrantFiled: December 15, 2014Date of Patent: February 20, 2018Assignee: The Johns Hopkins UniversityInventors: Daniel J. Rogers, Stergios J. Papadakis, Layne R. Churchill, Chee Wei Wong

Publication number: 20150338329Abstract: An apparatus and method to analyze fluid degradation in a closed system is disclosed. The method includes collection of a sample fluid from the closed system. The sample fluid collected is maintained at a sample fluid pressure, which is substantially equivalent to a pressure of the closed system. Thereafter, a change of a volume of the sample fluid is caused, which generates a change in the sample fluid pressure. A series of sample fluid pressures and volumes of the sample fluid are taken. Next, a bulk modulus of the sample fluid is determined. The bulk modulus of the sample fluid is compared with a baseline bulk modulus. Lastly, the method involves generation of a communication when the bulk modulus of the sample fluid breaches a tolerance.Type: ApplicationFiled: July 30, 2015Publication date: November 26, 2015Applicant: Caterpillar Inc.Inventors: EMILY A. MORRIS, JEFFREY L. KUEHN, MARTIN J. MORRIS, MARIO MEDINA, EMERY P. HALVERSON, TYLER R. PORT, CHRISTOPHER R. CHURCHILL, JOHN REVALLO, V, CHRISTOPHER L. ADOLPHSON

Publication number: 20070083202Abstract: An intramedullary bone plate with sheath having an intramedullary stem, a bone plate head and a neck that connects the intramedullary stem to the bone plate head in a manner where the stem and head are offset from each other longitudinally and axially in the sagittal plane. The bone plate head includes a sheath recess wherein non-threaded bone screw holes and a threaded sheath screw hole are located. Bone screws are inserted through the sheath recess and oriented at set angles allowing for bone fragment fixation and fracture reduction. A sheath element is placed within the boundaries of the sheath recess and secured with the sheath screw. The intramedullary stem includes longitudinal flutes in its distal portion and a bi-arced geometry in its proximal portion providing for stabilization of the implanted device. The bone plate head configuration provides for more complete fracture capture and multiple fixation modalities.Type: ApplicationFiled: September 20, 2005Publication date: April 12, 2007Inventors: Donald Eli Running, Jeffrey Ondrla, Thomas Hunt, R.

Patent number: 4643428Abstract: In combination with a golf glove, a strap for maintaining a golfer's hands in close relatively tight relation to each other when the golf club is gripped for hitting a golf ball. The strap includes a loop at one end into which the golfer's right thumb is placed, if the golfer is right handed and the left thumb if the golfer is left handed. The strap is provided at its other end with an attachment device for detachably securing that end of the strap to the golfer's glove overlying the back of the left hand of the golfer or right hand if the golfer is left handed. The attachment device comprises a plurality of hook and loop members mounted on a pad attached to the free end of the strap and arranged to intermesh with a material including loops and hooks secured to the golfer's glove closure.In use the attachment device is detachably pressed into the hooks and loops on the golf glove meshing therewith.Type: GrantFiled: July 3, 1985Date of Patent: February 17, 1987Inventor: George R.
