Patent number: 8254847Abstract: Ad-hoc networks employing cooperative signal processing are configured for detecting, identifying, and visualizing radio communication networks used by an adversary, such as enemy combatants or criminals. These networks are further configured for performing a non-passive tactical response to an adversary's communication capabilities. Such ad-hoc networks are particularly useful for identifying radio communication resources, establishing radio links, and subverting an adversary's communication capabilities in environments lacking available communication infrastructure, including battlefield environments, and locations where communication infrastructure is non-existent or has been compromised by natural disasters or terrorists attacks.Type: GrantFiled: April 16, 2008Date of Patent: August 28, 2012Assignee: Department 13, LLCInventor: Robi Sen

Patent number: 8254738Abstract: The present application is directed towards systems and methods for efficient installation of optical and electrical cable in watercraft. A manufacturer may terminate one end of a cable in a location removed from the watercraft, allowing use of automated cable termination machines for efficiency and consistency of terminations. The single-terminated cable may then be brought to the watercraft and installed by pulling or routing the unterminated end through ductwork and pipes, watertight bulkhead throughways, and cable trays and ladders as necessary, prior to termination. Accordingly, more difficult and expensive on-site labor is reduced, and reliability is greatly increased. Furthermore, many cable tests that require termination but cannot be executed post-installation can be performed prior to installation, to ensure that at least the first termination, performed off-site, is error-free, reducing later troubleshooting and further increasing installation efficiency.Type: GrantFiled: August 27, 2010Date of Patent: August 28, 2012Assignee: kSARIA CorporationInventors: Sebastian J.

Patent number: 8215847Abstract: Communications connectors communicatively and physically join a plurality of network elements. Communications connectors are substantially flangeless so as to provide a substantially continuous surface between the connector and network elements joined thereto. Communications connectors may include or be modified with a grounding surface or a seating member. Communications connectors include a variety of communicative contact surfaces and joining mechanisms, including those compatible with known 7/16 DIN connections. Methods include installing network elements to connection interfaces on connectors without the use of a flange or other exterior part. Methods optionally include applying an adhesive to connection interfaces to provide a breakable, locked connection between network elements and connectors.Type: GrantFiled: January 28, 2010Date of Patent: July 10, 2012Assignee: Alcatel LucentInventors: Michael J.
