  • Publication number: 20240122276
    Abstract: 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.

    Abstract: A method of forming a multi-chip system is disclosed. The method includes forming one or more bumps on respective conductive contact pads of a first electronic device, forming one or more mini-bumps on respective conductive contact pads of a second electronic device, and aligning respective one or more mini-bumps with respective one or more bumps. The method further includes performing a bump bonding process that exerts compression force on one or both the first electronic device and the second electronic device to compress the one or more mini-bumps into the one or more bumps to form one or more bump bond structures that bond the second electronic device to the first electronic device.

  • Patent number: 11727386
    Abstract: 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.

  • Publication number: 20230138933
    Abstract: 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.

  • Patent number: 11616187
    Abstract: 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.

  • Patent number: 10340568
    Abstract: An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, ?r that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.
