Patent number: 7664512Abstract: A geolocation system (10) includes an emitter (12), a plurality of collection nodes (14,16,18), and a control station (20). Each collection node includes a receiver (24) that is operable to receive signals transmitted from the emitter (12), generate a reduced data stream that includes only signal data, and communicate the reduced data stream to the control station (20) along with navigation data. The receiver (24) identifies signal data by detecting an energy level of the raw collection data. More specifically, the receiver (24) determines a bandwidth and a signal-to-noise ratio of each portion of the collection data, and identifies each portion as including signal data if both the bandwidth and the signal-to-noise ratio exceed predetermined threshold amounts. The receiver (24) includes a digital signal processing component (36) for performing calculations used by the receiver (24) to determine the bandwidth and the signal-to-noise ratio.Type: GrantFiled: August 10, 2006Date of Patent: February 16, 2010Assignee: L3 Communications Integrated Systems, L.P.Inventors: Hyo K Chung, Phuong H Le, John M Parker, David L Reid, Mark A Robertson

Patent number: 7651401Abstract: The method of forming self-attaching female fasteners by rolling a continuous metal strip including a central pilot portion having parallel sides and flange portions on opposed sides, severing at least the pilot portion and cold forming the rectangular pilot portion into a cylindrical end portion. Wing-shaped radial portions are formed in the pilot portion which may be severed or remain for anti-rotation features. The strip may remain continuous, wherein the severed pilot portions are spread and the flange portions are thinned or the strip may be severed into discrete fasteners. The female fasteners thus include generally cylindrical pilot portions and rectangular flange portions which may include rolled grooves.Type: GrantFiled: November 24, 2003Date of Patent: January 26, 2010Assignee: Whitesell International CorporationInventors: Harold A.

Patent number: 7626546Abstract: Systems and methods for detection and geolocation of multiple emitters that are emitting RF signal energy on a common frequency, and that may be implemented to separate, geolocate, and/or determine the number of emitters (e.g., radio users) emitting on a common RF frequency. Real-time signal qualification processing may be employed to continuously monitor and collect incoming receiver tuner data for signal activity and ignore irrelevant noise data. Each set of data blocks from an emitter transmission signal may be defined as an emission cluster, and a set of time difference of arrival (TDOA)/frequency difference of arrival (FDOA) pairs may be computed for each emission cluster with each TDOA/FDOA pair yielding a geolocation result. A statistical qualification method may be used to produce a final geolocation answer from each set of emission cluster geolocation results, and a geolocation error ellipse computed for the final geolocation answer of each emission cluster.Type: GrantFiled: September 27, 2007Date of Patent: December 1, 2009Assignee: L-3 Communications Integrated Systems L.P.Inventors: Hyo K.
