Patent number: 10542093Abstract: Embodiments of a sensor network system provide surveillance capabilities in multiple contexts/environments (e.g., military, commercial, scientific, civic, urban, wilderness, etc.). Network nodes may include devices such as sensors, network routers, network controllers, etc. Network sensors may be configured so that power management objectives are maximized. Network sensors (both individually and as a group) may be capable of intelligent and cooperative information gathering, so that the output of the sensor network does not contain high levels of irrelevant information. The network nodes may communicate among one another via one or more communication links, and in some cases, multiple routes between any two network nodes may be available. The sensor network may include aspects of both high data rate and low data rate network features.Type: GrantFiled: September 1, 2011Date of Patent: January 21, 2020Assignee: The Boeing CompanyInventors: Arun Ayyagari, Kevin Y.

Patent number: 7164656Abstract: Techniques for communicating data through a network so as to satisfy various Quality Of Service (“QOS”) levels are described. The QOS levels may be selected based on a determined type of the data or the data communication, such as by a network manager after the data communication is registered, and QOS communication parameters are selected for the data communication to ensure that the QOS levels are achieved. Other techniques may also be used to ensure that a selected QOS level is achieved, including selecting an appropriate path through the network, controlling other data communications that use some or all of the selected path, and/or enabling preemption of such other data communications. QOS levels that are actually achieved may also be monitored, and the QOS communication parameters and/or path for a data communication may be dynamically modified based on differences between actual achieved QOS levels and desired QOS levels.Type: GrantFiled: April 19, 2002Date of Patent: January 16, 2007Assignee: The Boeing CompanyInventors: Michael S.

Patent number: 7068667Abstract: A method and system for managing an interconnect fabric that connects nodes. A network manager manages an interconnect fabric or network of routing devices (e.g., interconnect fabric modules, switches, or routers) to allow source nodes to transmit data to destination nodes. The network manager receives registration requests from source nodes to send data to destination nodes, configures the routing devices of the network to establish a path from each source node to its destination node, and provides a virtual address to each source node. The virtual address identifies a path from the source node to the destination node. The source node sends the data to its destination node by providing the data along with the virtual address to a routing device of the network.Type: GrantFiled: October 26, 2001Date of Patent: June 27, 2006Assignee: The Boeing CompanyInventors: Michael S. Foster, Michael A. Dorsett

Patent number: 7068666Abstract: An interconnect fabric module (“IFM”) with high-speed switching capabilities. An interconnect fabric module can be dynamically configured to interconnect its communications ports so that data can be transmitted through the interconnected ports. Multiple interconnect fabric modules can be connected to form an interconnect fabric through which nodes (e.g., computer systems) can be interconnected. In one embodiment, data is transmitted through the interconnect fabric as frames such as those defined by the Fibre Channel and InfiniBand standards. The interconnect fabric module allows the creation of an interconnect fabric that is especially well suited for interconnecting devices utilizing multiple information types such as might be required by the devices of an enterprise data network (“EDN”).Type: GrantFiled: October 26, 2001Date of Patent: June 27, 2006Assignee: The Boeing CompanyInventors: Michael S.

Patent number: 7042877Abstract: A method, system, and computer-readable medium for integrating multiple techniques for processing data communications is described in which the processing steps shared by multiple of the techniques do not have to be duplicated by each of the techniques. In some situations, some or all of the multiple processing techniques are performed in parallel, such as on different processors. In some situations, a Multi-Protocol Edge Switch (“MPEX”) is used to integrate multiple processing techniques for received data communications that are to be forwarded to a destination, such as by performing protocol translation, performing load balancing between multiple alternative destinations on one or more of the networks to which the MPEX belongs, performing firewall and other content-based analysis for any or all of the nodes on one or more of the networks to which the MPEX belongs, and/or providing content-based routing of data communications in order to identify appropriate destinations.Type: GrantFiled: October 26, 2001Date of Patent: May 9, 2006Assignee: The Boeing CompanyInventors: Michael S. Foster, Michael A. Dorsett

Patent number: 7034938Abstract: A Non-Scanning Computed Tomography Imaging Spectropolarimeter (NS-CTISP) measures all spatial, spectral and polarimetric information simultaneously in an image scene allowing measurement of dynamically changing scenes. In particular, NS-CTISP uses division of aperture to polarimetrically analyze each divided image, all of which are thereafter diffracted to measure irradiance on a focal plane array. The Stokes object cube data for each voxel is thereafter estimated from an inverse of the voxel polarimetric calibration matrix for the optical components.Type: GrantFiled: February 4, 2002Date of Patent: April 25, 2006Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Brian H.
