Abstract: According to an aspect, there is provided a superconductor connector assembly for electrically connecting a first superconductor cable and a second superconductor cable, the superconductor connector assembly comprising: at least one first superconducting cable terminal, the first superconducting cable terminal comprising at least one first opening for receiving an end of the first superconductor cable; at least one second superconducting cable terminal, the second superconducting cable terminal comprising at least one second opening for receiving an end of the second superconductor cable; and a surrounding part that is configured to receive and surround the first superconducting cable terminal and the second superconducting cable terminal, wherein the first and second openings overlap when the first superconducting cable terminal and the second superconducting cable terminal are received in the surrounding part, wherein the surrounding part is made from a material that has a thermal expansion coefficient diff

Abstract: A duct stringer assembly with a bulkhead. The duct stringer assembly has duct walls providing a duct with a closed cross-section. The duct is adapted to transport fluid. A bulkhead is in the duct, and the bulkhead is adapted to block the flow of fluid along the duct. The bulkhead has a bulkhead body, and a gasket sealing a gap between the bulkhead body and the duct walls.

Abstract: A self-contained hand held mobile payment electronic device and method eliminates any use of cash or credit in making a payment from one party to another party who are both members of an association of parties, each party possessing one of the devices to execute a financial transactions between those parties. The devices all are capable of storing a credit balance deposited therein from a financial institution or other source of funds owned by the parties and transferring a payment from one party to another party of the association when the respective devices are positioned adjacent each other. A biometric sensor on each device enables transactions to be executed only when the paying party holds a finger or thumb on the biometric sensor which also indentifies the party.
