Publication number: 20240122276Abstract: Aspects herein are directed to an apparel item that promotes thermo-regulation through the use of engineered openings, venting, and/or stand-off structures. In exemplary aspects, 20-45% of the apparel item may comprise the engineered openings. Vents may be positioned on the apparel item in areas that experience high amounts of air flow to help channel air into the apparel item. The stand-off structures may be positioned on an inner-facing surface of the apparel item where they help to create a space between the apparel item and the wearer's body surface in which air can flow and help cool the wearer by promoting evaporative cooling.Type: ApplicationFiled: December 8, 2023Publication date: April 18, 2024Inventors: Collin Bailey, Kim D. Baschak, Olivia A. Echols, Stacey L. Hansen, Lucas Hartman, Rebecca P. Hurd, Adam Parkinson, Shannon K. Redell, David Sagan, Susan L. Sokolowski, Stuart B. Brown, Matthew J. Hancock

Patent number: 11727386Abstract: A transaction is detected on a transaction terminal. A first code is presented on a display of the transaction terminal that is encoded with an identifier and a passcode for a wireless connection between the transaction terminal and a mobile device operated by a customer. The mobile device processes the code to wirelessly connect to the transaction terminal using the identifier and the passcode. A second code is presented on a display of the transaction terminal. The second code when captured by the mobile device causes a transaction interface to be remoted from the transaction terminal to the mobile device over the wireless connection. The transaction continues with interactions provided on the mobile device and processed on the transaction terminal without any customer touching of the display of the transaction terminal and without any customer touching of any keys or keypad of the transaction terminal.Type: GrantFiled: May 18, 2020Date of Patent: August 15, 2023Assignee: NCR CorporationInventors: William Harrison McGraw, IV, Deepak Aladahalli Puttaswamy, Michael David Hartman

Publication number: 20230138933Abstract: A cable reel for retaining a continuous length of cable is preferably constructed using an inexpensive plastic material, such as corrugated plastic. In one embodiment, the cable reel includes a hollow tubular core with a set of outward radial tabs integrally formed at each of its ends. A single, disc-shaped, interior support flange is mounted within the interior of the core in circumferential contact therewith to provide structural rigidity. Additionally, on each end of the core, an annular inner flange and a disc-shaped outer flange are disposed in coaxial alignment with one another against opposing surfaces of its corresponding set of radial tabs and are fixedly secured together as part of the assembly process. The multi-flange construction enables the thickness, diameter and/or material properties of the ends of the cable reel to be adjusted, as needed, to accommodate the strength and dimensional requirements of the intended application.Type: ApplicationFiled: November 3, 2022Publication date: May 4, 2023Inventors: Fred Dowd, Roger L.

Patent number: 11616187Abstract: Test structures and methods for superconducting bump bond electrical characterization are used to verify the superconductivity of bump bonds that electrically connect two superconducting integrated circuit chips fabricated using a flip-chip process, and can also ascertain the self-inductance of bump bond(s) between chips. The structures and methods leverage a behavioral property of superconducting DC SQUIDs to modulate a critical current upon injection of magnetic flux in the SQUID loop, which behavior is not present when the SQUID is not superconducting, by including bump bond(s) within the loop, which loop is split among chips. The sensitivity of the bump bond superconductivity verification is therefore effectively perfect, independent of any multi-milliohm noise floor that may exist in measurement equipment.Type: GrantFiled: February 5, 2021Date of Patent: March 28, 2023Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: Aurelius L.
