  • Patent number: 8880381
    Abstract: Systems and methods for optimizing processor requirements for a complex hardware system are disclosed. A set of complex hardware system configuration constraints are formulated as an objective function and a set of linear inequalities, and a convex polytope is formed from the set of linear inequalities. The objective function is optimized over the convex polytope using mixed integer linear programming means to obtain an optimal solution. Processor requirements for the complex hardware system are determined based on the optimal solution.

  • Patent number: 8686854
    Abstract: A software module apparatus for enabling a user to generate a virtual tripwire through a geographic area of interest using a plurality of sensors. The apparatus may make use of an input for allowing a user to input a digital elevation model (DEM) of the area of interest. An input responsive to a user controlled device may also be used for defining a swath of the area of interest, the swath representing a subregion laying over, or adjacent to, a border to be monitored. A display may be generated for illustrating computed locations of a plurality of independent sensors used to form the virtual tripwire through the swath of the area of interest.

  • Patent number: 8666699
    Abstract: A method for optimum sensor layout for detecting an intruder may include selecting candidate sensor locations within a representation of an area of regard. The method may also include determining a sub-region of detection for each sensor based on a preset probability of detection of the intruder traversing a sub-region associated with each sensor. The method may additionally include determining each pair of sensors with overlapping sub-regions of detection and determining a lowest probability of detection for any path between each pair of sensors with overlapping sub-regions of detection. The method may further include determining an optimum layout of sensor locations or sensors from candidate sensor locations based on a path of the lowest probability of detection for any path between each pair of sensors with overlapping sub-regions of detection.

  • Patent number: 8370111
    Abstract: A method for forming a virtual tripwire through a subregion of an area of interest. The method may involve performing a geometric analysis of terrain in the subregion, the geometric analysis determining a location for each one of a pre-designated plurality of candidate sensors that may potentially be used in forming the virtual tripwire. A viewshed for each candidate sensor is determined. Each viewshed represents a coverage region for its associated candidate sensor. A geometric beginning point and a geometric end point within the subregion are each defined for the virtual tripwire. The viewsheds are analyzed to determine a number of the candidate sensors required to form a path for the virtual tripwire from the beginning point to the end point.

  • Publication number: 20040260813
    Abstract: An embodiment of the present invention includes a method to generate a network design. Candidate hubs for a wireless network are generated from a database of available hubs using a first set of criteria. A service level availability (SLA) is associated to each of the candidate hubs using a second set of criteria. A set of network configurations is generated from the candidate hubs. Each of the network configurations maximizes customer coverage and satisfies the associated SLA.
