Patent number: 8499173Abstract: A method and system for protecting a printed circuit board (PCB) from tampering positions a physical sensor proximal to the PCB. An initialization period is established and an output signal from the sensor is continuously monitored to establish threshold parameter data. Periodically, the sensor is polled and an output signal received which is compared to the threshold parameter data. A detected intrusion signal is generated if the received signal exceeds the threshold by a predetermined level. A detected intrusion is validated using a sent of validation rules which analyze the detected intrusion based on historical sensor output values and factors such as duration or frequency of intrusion detections. If the detected intrusion is validated, a validated signal is generated which triggers a reset processor to output a reset signal that causes erasure of at least a portion of onboard memory.Type: GrantFiled: November 23, 2010Date of Patent: July 30, 2013Assignee: Lockheed Martin CorporationInventor: J.

Patent number: 8279100Abstract: A Complex Analog to Digital Converter System on Chip (CADC SoC) implemented into a microcircuit system is provided. A series of stagger clock signals can be fixed on either a rising or falling edge of the system clock and a plurality of A/D converters can be grouped by sets (i.e. odd and even) and assigned to odd or even stagger clocks. A complex I&Q data manager is provided for controlling the system. A clock management system is responsive to an external signal to select from a set of stagger clock settings, thereby improving anti-alias performance.Type: GrantFiled: September 30, 2010Date of Patent: October 2, 2012Assignee: Lockheed Martin CorporationInventors: J. Claude Caci, Byron W. Tietjen, Kevin H. Wilson

Patent number: 7599289Abstract: An electronic communication control device suitable for embedding into a network interface card or a line card of a switch or router. The electronic communication control device is capable of communications in multiple protocols. The processing architecture of the electronic communication control device may be adapted for any communications protocol and may be well suited for Internet protocol. The electronic communication control device may perform protocol translation, for example, between IPv4 and IPv6. An exemplary embodiment of the electronic communication control device includes a parallel processing chipset operating on multiple busses with embedded software. The electronic communication control device provides a hardware architecture upon which embedded software may operate to provide services, such as, for example, system control, packet analysis, packet filtering, translation services, switching, routing and/or multiplexing control.Type: GrantFiled: May 13, 2005Date of Patent: October 6, 2009Assignee: Lockheed Martin CorporationInventor: J.

Patent number: 7272468Abstract: A method and apparatus for housing an electronic device are provided. The apparatus includes an environmentally sealed chamber to protect the electronic device from harsh environments. The environmental conditions of the chamber are controllable using environmental controls which are controlled by digital processor with a stored program coupled with sensors. The digital processor may also control the application of power from an external interface. The apparatus also includes a self-contained power source running from a primary fuel. A control system is provided for managing power production and energy storage to maintain continuity of environmental conditions.Type: GrantFiled: January 12, 2005Date of Patent: September 18, 2007Assignee: Lockheed Martin CorporationInventors: J. Claude Caci, David L. Vos

Patent number: 7224985Abstract: Disclosed is an antenna segment system for communicating between fixed antenna segments and wireless mobile devices. The antenna segments may be embedded in lighting fixtures distributed in a building. Each lighting fixture may emanate a visible light pattern related to an antenna pattern of an antenna segment embedded in the respective lighting fixture. The system includes a computer that can automatically assign addresses to the distributed antenna segments based on time domain reflection signals returned over a wire path between a controller and the segments.Type: GrantFiled: January 16, 2003Date of Patent: May 29, 2007Assignee: Lockheed Martin, Corp.Inventor: J.

Patent number: 7050787Abstract: Disclosed is a cooperative element location system especially useful for locating a cellular telephone making a call from an unknown location. The call may be a request for emergency assistance, or for location-based commercial services, for example. Various embodiments may optionally include a mobile location component, a cellular telephone enabled to chirp-on-demand, and/or an interferometer link. A mobile location component may include a directional antenna. The directional antenna may be mounted on an antenna boom on top of an emergency vehicle, for example. The mobile location component may alternately or additionally comprise a hand-held unit. System elements may cooperate to generate a situation awareness map or other display. The mobile location component may be moved in the general direction of a first location calculation associated with a first circular error of probability.Type: GrantFiled: October 30, 2003Date of Patent: May 23, 2006Assignee: Lockheed Martin CorporationInventor: J.
