Patent number: 11962079Abstract: The embodiments include an array in intimate adjacent contact with a substrate foundation. The array has a plurality of radio frequency (RF) witness films overlain on the substrate foundation. Each RF witness film is a unit cell defined in a three-dimensional coordinate frame of reference, and is centered at an origin of the three-dimensional coordinate frame of reference. Each RF witness film in the plurality of RF witness films is equally-spaced from adjacent RF witness films.Type: GrantFiled: January 25, 2022Date of Patent: April 16, 2024Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Zachary A. Sechrist, Christopher G. Yelton, Mark B. Moran, Linda F Johnson, Joseph E. Estevez, Gretchen H. Hefley

Patent number: 10197490Abstract: An apparatus for measuring volumes of two or more immiscible fluids, a lighter fluid and a heavier fluid, in a core sample includes a fluid separator and two volume pressure actuators. The lighter fluid accumulates in an upper portion of the fluid separator and the heavier fluid accumulates in a lower portion of the fluid separator, with a meniscus forming between the lighter fluid and the heavier fluid. The first and second volume pressure actuators have fluid volume encoders that determine a net volumetric flow of the fluids to and from the fluid separator. The first and second volume pressure actuators also collectively maintain constant back pressure on the fluid separator and maintain the meniscus between the two immiscible fluids in the fluid separator at a constant position.Type: GrantFiled: May 16, 2016Date of Patent: February 5, 2019Assignee: DCI CORPORATIONInventors: Christopher F. Johnson, Christopher Scott Johnson, Andrew C. Johnson, Steven W. Derr

Patent number: 9693921Abstract: A patient transfer sled has a support structure including at least one air cushion adjacent a major surface thereof. The air cushion includes a flexible material at least partially surrounding a rigid material, and a portion of the flexible material has a plurality of holes extending therethrough. Systems for patient transfer may include a support surface, such as a table, a patient transfer sled having at least one air cushion, and a source of pressurized air. Methods for moving a patient relative to a support surface include positioning a patient on a patient transfer sled having at least one air cushion, and inflating the air cushion with air to form a sheet of flowing air between the patient transfer sled and the support surface. The methods may be used, for example, to move a patient on an air film over a surface within a system.Type: GrantFiled: January 29, 2014Date of Patent: July 4, 2017Assignee: DIACOR, Inc.Inventors: Michael R. Koger, Kevin R. Anderson, Frederic A. Gibbs, Jr., Christopher F. Johnson

Patent number: 9382762Abstract: A subterranean drilling system may include a drill string and a rotary drill bit coupled to the drill string. The rotary drill bit may include a bit body and a cutting element coupled to the bit body, with the cutting element being structured to rotate in response to torque applied to the cutting element. The system also may include a cam assembly coupled to the drill string, a cam follower assembly in contact with a cam surface of the cam assembly, and a torque-applying structure coupled to the cam follower assembly. The torque-applying structure may be configured to apply torque to the cutting element in response to relative rotation between the cam assembly and the cam follower assembly.Type: GrantFiled: December 4, 2014Date of Patent: July 5, 2016Assignee: US Synthetic CorporationInventors: Craig H. Cooley, Timothy N. Sexton, S. Barrett Peterson, Jeffrey Lund, Christopher F. Johnson

Patent number: 8656528Abstract: A patient transfer board including an elongated board body that extends lengthwise along a longitudinal axis between leading and trailing ends of the board body. The transfer board has a top side and an underside of the board body. The underside includes first and second side edges that extend along the longitudinal axis. The underside includes alignment slots having respective openings at the first side edge. The alignment slots are defined by interior sidewalls. The alignment slots are configured to receive reference elements of the patient table through the respective openings when the transfer board is moved in a lateral direction that is generally transverse to the longitudinal axis. The sidewalls are configured to engage the corresponding reference elements and direct the transfer board toward a designated position.Type: GrantFiled: June 5, 2012Date of Patent: February 25, 2014Assignee: General Electric CompanyInventors: Benjamin Perelman, Liyong Wu, Roman I.
