System and method for zero latency, high fidelity emergency assessment of airborne chemical, biological and radiological threats by optimizing sensor placement

Patent image
NRL

Networked groups of sensors that detect Chemical, Biological, and Radiological (CBR) threats are being developed to defend cities and military bases. Due to the high cost and maintenance of these sensors, the number of sensors deployed is limited. It is vital for the sensors to be deployed in optimal locations for these sensors to be effectively used to analyze the scope of the threat. A genetic algorithm, along with instantaneous plume prediction capabilities meets these goals. An analyzer's time dependant plumes, upwind danger zone, and sensor capabilities are used to determine the fitness of sensor networks generated by the genetic algorithm.

System and method of improved kalman filtering for estimating the state of a dynamic system

Patent image
NRL

Embodiments include systems and methods of estimating at least one state of a modeled dynamic system. In particular, in one embodiment, an observer such as an extended Kalman filter is used to estimate the state of a modeled dynamic system. A covariance matrix associated with state variables of the observer is periodically checked for compliance with a specified condition, e.g., positive definiteness. If the matrix deviates from the specified condition, the matrix is set to a specified value.

Patent image
ACERDEC

An information system, method, and computer program product is provided for the semi-distributed warning of existing or developing significant events and/or threats to all network bridges in the system, and then to affected users carrying a user warning and positioning device, while reporting the location of all user's carrying the user warning and positioning devices of the system to existing command and control systems. The present invention's future event warning capabilities permit those same users to be warned of impending events in enough time for the users to take positive actions in response to these events and/or address those events. The system of the present invention includes a pager-like user warning and positioning device, worn by or carried by the individual user, or mounted in a vehicle or vessel, having a geographical positioning means therein, which periodically transmits the geographical location of the individual user, vehicle or vessel to local network bridges, and listens for warning/notification event messages transmitted by the local network bridge. When an event/threat warning is received by an affected user warning and positioning device, the pager-like user warning and positioning alerts the user via indicia relative to the event/situation, including audible spoken warnings and instructions on how to react, and may retransmit the event/threat warning to other user warning and positioning devices in the network, provided the threat has not occurred and the event/threat warning has not been previously relayed.

System and method for navigating an unmanned undersea vehicle (UUV) using three-dimensional acoustic reflectivity data sets and a beam steered downward looking sonar capturing sub-bottom features and creating three-dimensional representations to compare with the reflectivity data sets to general navigation corrections. Acoustically senses and exploits sub-bottom features for navigation of UUVs that can provide more reliable navigation than using surface features alone, since much of the sea floor is flat (e.g. on continental shelves and abyssal plains).
