Patent number: 8747126Abstract: An adapter is provided for electrically connecting an interior surface of a conduit and an external surface of a cable. The adapter includes a flat strip extending longitudinally from first to second ends with first and second transverse edges and composed of an electrically conductive and mechanically flexible material. The strip includes a longitudinal ribbon that forms a ring for wrapping around the cable by curling the first and second ends together in a direction transverse to the sheet, and a plurality of first and second incisions from the transverse edges towards the ribbon, the incisions being disposed at respective intervals that correspond to a longitudinally regular pattern. The first incisions form tapering tabs for bending in the direction transverse to the sheet to produce petals that extend radially inward from the ring to engage the cable.Type: GrantFiled: October 10, 2013Date of Patent: June 10, 2014Assignee: The United States of America as Represented by the Secretary of the NavyInventors: Blaise L.

Patent number: 8723390Abstract: A flux compression generator (FCG) is provided for producing an electromagnetic pulse (EMP). The FCG includes an environmental case, a reactive load, a dielectric core, a superconducting stator, an electric energy source, a load switch, and a transition device. The reactive load transmits the EMP in response to an electric current pulse. The dielectric core has proximal and distal ends within the case, with the stator disposed coaxially around the core that provides structural support. The case contains the electrical energy source, the stator, the core and the transition device. The energy source connects to the stator at the proximal end and powers the transition device. The load switch connects the reactive load to the stator at the distal end. The energy source initially provides an electric current to the stator. The device upon activation heats at least a portion of the stator to reversibly transition the portion from a superconducting state to a non-superconducting state.Type: GrantFiled: November 10, 2010Date of Patent: May 13, 2014Assignee: The United States of America as Represented by the Secretary of the NavyInventors: Blaise L.

Patent number: 7483671Abstract: In one general aspect, a communications system as described herein provides a wide-band jamming signal that is digitally created, conditioned, and modified by a processing based system to provide open data channels to authorized parties within a jammed communications band. The communications system modifies and maintains the open data channels to sustain communications between authorized devices. In addition, the communications system provides frequency hopping using the open data channels to supply secure data links to authorized devices within the jammed communications band while denying service to unauthorized communication nodes or devices.Type: GrantFiled: May 19, 2005Date of Patent: January 27, 2009Assignee: The United States of America as represented by the Secretary of the NavyInventors: Blaise L.

Patent number: 7417707Abstract: An intermediary layer is introduced between a lens and a wafer for an immersion lithography process. A non-supercritical gas is provided and condensed to form a layer of liquid between the lens and the wafer. The substrate may be irradiated through the lens and intermediary layer. In addition, the intermediary layer may then be evaporated. The non-supercritical gas may include superheated steam which may be condensed to form a layer of water between the lens and the wafer. The wafer may be irradiated with one of a EUV light and UV light. A system for introduction of an intermediary layer between a lens and a wafer for an immersion lithography process is also provided. The wafer for use in the immersion lithography process may includes a hydrophobic and hydrophilic surfaces to provide enhanced contact angles between the wafer and the intermediary liquid layer condensed on the wafer and to reduce light aberration provided from a light source through the intermediary liquid layer.Type: GrantFiled: June 29, 2006Date of Patent: August 26, 2008Inventor: Blaise L.

Patent number: 7388497Abstract: Radio frequency identification (RFID) includes far-field systems associated with an RFID interrogator and an RFID tag. The RFID interrogator produces continuous wave (CW) unmodulated signals selected from frequencies comprising a predetermined frequency band. The RFID tag includes reception and transmission antenna circuits, a signal processor, and an oscillator. The reception antenna circuit receives the reception signals from the RFID interrogator. The signal processor determines whether the reception signals correspond to a plurality of tag identification frequencies as a correlation. The signal processor also produces responsive signals in response to the correlation. The oscillator supplies a carrier frequency. The transmission antenna circuit combines the carrier signal with the response signals to produce transmit signals, and then dispatches the transmit signals.Type: GrantFiled: February 1, 2006Date of Patent: June 17, 2008Assignee: The United States of America as represented by the Secretary of the NavyInventors: Blaise L.
