Patent number: 7453041Abstract: A superconducting cable assembly includes a first annular passage disposed concentrically around the superconducting cable and having first and second ends and an inlet, a second annular passage disposed concentrically around the first passage and having first and second ends, wherein at least one of the first and second ends of the second passage is in communication with at least one of the first and second ends of the first passage, the second passage further having an outlet. A coolant provided by a cryogenic refrigeration system is directed through the inlet, passes through the first passage in a first direction, passes through the second passage in a second direction opposite to the first direction and exits the assembly through the outlet. With this arrangement, the superconducting cable is cooled to the critical temperature by coolant flowing through the first passage and the coolant flowing through the second passage intercepts ambient heat so as to act as a heat shield for the first passage.Type: GrantFiled: June 16, 2005Date of Patent: November 18, 2008Assignee: American Superconductor CorporationInventors: James F.

Patent number: 6850269Abstract: A process and a system for receiving compressed streaming video image data, simultaneously and continuously from a plurality of mobile sources, which stamp the data with time, location, and source identification. The data is processed by converting the location stamps to road vector identifications. The time, road vector and source are compared with those of other data received previously and being received concurrently to develop and revise a record comprising a reference to the most recent data, for each road vector and the speed of the mobile source. The data is stored and is retrieved by selected road vector, to display a continuous and coherent video image of the most recently recorded view at the selected road vector, together with the speed of the data source.Type: GrantFiled: December 3, 2001Date of Patent: February 1, 2005Inventor: James F.

Patent number: 6625992Abstract: A cryogenic cooling system is configured to control the flow of a heat transfer fluid through a remote thermal load, such as a superconducting magnet or rotor. The cryogenic cooling system includes a refrigerator including a cryogenically cooled surface and a cryogenic fluid transport device disposed for circulating a heat transfer fluid between the cryogenically cooled surface and the remote thermal load. The cryogenic fluid transport device advantageously serves as device for providing the necessary mechanical force necessary to move the heat transfer fluid from the cryogenically cooled surface (e.g., end of a cryocooler) to the remote thermal load. Thus, unlike conventional cooling arrangements the heat transfer fluid does not require a phase change.Type: GrantFiled: January 29, 2002Date of Patent: September 30, 2003Assignee: American Superconductor CorporationInventors: James F.
