Patent number: 8730088Abstract: Techniques disclosed herein include systems and methods for accurately scheduling radar and radio events against each other. Specifically, a scheduling manager can schedule radar events based on scheduled radio events (wireless network communication events). A given radio schedule for a compact radar sensor can be a relatively complicated schedule, especially when the compact radar sensor operates as part of an ad hoc network. In certain embodiments, the scheduling manager identifies a radio transmission schedule of neighboring radar nodes or compact radar sensor units. Such a radio transmission schedule of neighboring nodes can include information on when neighboring nodes will be receiving or transmitting data. The scheduling manager then schedules radar events to be executed by the radar device at available times, or at times that do not overlap with scheduled radio events.Type: GrantFiled: January 5, 2011Date of Patent: May 20, 2014Assignee: Raytheon BBN Technologies Corp.Inventors: Stephen D. Milligan, Jason Redi, Jonathan Fisher, Daniel Sumorok, Steven W. Weeks

Patent number: 8732330Abstract: A system for performing packet based data communications over a parallel set of sublinks is provided. A transmitter unit separates the sublinks into an available set of sublinks and a busy set of sublinks. This transmitter avoids processing delays by utilizing sublinks in the available sublink set and not waiting for sublinks in the busy sublink set to be released. To receive the packets, a receiver unit utilizes a sequence number associated with each packet. Accordingly, the receiver extracts the one or more packets of data received in parallel over the set of sublinks in sequential order. A packet window buffer is used to store packets in sequence if they are initially received out of order. The receiver utilizes a sliding window to provide packets in continuous sequential order and transmits the packets serially over a single communication link.Type: GrantFiled: March 12, 2002Date of Patent: May 20, 2014Assignees: Verizon Corporate Services Group Inc., Level 3 Communications, LLC, Raytheon BBN Technologies Corp.Inventor: Craig Partridge

Publication number: 20140115687Abstract: A method and apparatus is disclosed for increasing the security of computer networks through the use of an Intrusion and Misuse Deterrence System (IMDS) operating on the network. The IMDS is a system that creates a synthetic network complete with synthetic hosts and routers. It is comprised of a network server with associated application software that appears to be a legitimate portion of a real network to a network intruder. The IMDS consequently invites inquiry and entices the intruder away from the real network. Simulated services are configured to appear to be running on virtual clients with globally unique, class āCā IP addresses. Since there are no legitimate users of the virtual network simulated by the IMDS, all such activity must be inappropriate and can be treated as such. Consequently, the entire set of transactions by an intruder can be collected and identified rather than just those transactions that meet a predefined attack profile.Type: ApplicationFiled: June 6, 2011Publication date: April 24, 2014Applicants: VERIZON CORPORATE SERVICES GROUP INC., RAYTHEON BBN TECHNOLOGIES CORP., LEVEL 3 COMMUNICATIONS, LLCInventors: Martin F.

Publication number: 20140099033Abstract: An approach to computation of kernel descriptors is accelerated using precomputed tables. In one aspect, a fast algorithm for kernel descriptor computation that takes O(1) operations per pixel in each patch, based on pre-computed kernel values. This speeds up the kernel descriptor features under consideration, to levels that are comparable with D-SIFT and color SIFT, and two orders of magnitude faster than STIP and HoG3D. In some examples, kernel descriptors are applied to extract gradient, flow and texture based features for video analysis. In tests of the approach on a large database of internet videos used in the TRECVID MED 2011 evaluations, the flow based kernel descriptors are up to two orders of magnitude faster than STIP and HoG3D, and also produce significant performance improvements. Further, using features from multiple color planes produces small but consistent gains.Type: ApplicationFiled: October 4, 2013Publication date: April 10, 2014Applicant: Raytheon BBN Technologies Corp.Inventors: Pradeep Natarajan, Shuang Wu, Rohit Prasad, Premkumar Natarajan

Patent number: 8657235Abstract: The systems and methods of the invention modulate atmospheric gases to temporarily increase the amount of atmospheric particles in the path of the debris, in order to decelerate the debris and accelerate natural orbital decay to the point of atmospheric re-entry. In one aspect of the invention, clearing the space debris includes propelling a plume of atmospheric gases substantially orthogonal to the path of the debris such that the debris collides with the gaseous plume as it passes through the plume. Increased atmospheric drag from the gaseous particles of the plume in the path of the debris obstructs a forward propagation of the debris and gradually decelerates the debris, leading eventually to atmospheric recapture.Type: GrantFiled: January 7, 2011Date of Patent: February 25, 2014Assignee: Raytheon BBN Technologies Corp.Inventors: Daniel Alan Gregory, John-Francis Mergen

Patent number: 8659424Abstract: A system to detect subsurface activity. The system employs vibration sensor pairs, with each sensor pair having a shallow sensor and a deep sensor. Outputs of the sensors of a pair are processed together and events are detected based on the relative values detected by the sensors of the pair. When signal energy departs from a detected background level, the relative amplitude and frequency content of vibrations measured at the shallow and deep sensors may be compared. The comparison may be performed, at least in part, using a classifier that discriminates between subsurface activity and surface activity. The outputs of sensor pairs may be aggregated to make a determination of whether subsurface activity exists and/or its location. Aggregation may involve comparing the outputs of the same sensor pair at multiple time intervals or may involve comparing the outputs of arrayed sensor pairs.Type: GrantFiled: February 9, 2010Date of Patent: February 25, 2014Assignees: Raytheon BBN Technologies, Corp., US Army Corps of EngineesInventors: Peter Allen Krumhansl, William Coney, Richard Mullen, Jason R.
