  • Patent number: 10558492
    Abstract: A system and method for planning radar missions. The system includes a processing unit and a display. The method includes estimating the execution time of a plurality of radar tasks to be executed periodically at respective planned repetition rates, and assessing, using rate monotonic scheduling, whether the tasks can be executed at their respective planned repetition rates. The display may be employed to display a graphical representation of a path to be flown repeatedly by the aircraft, and, superimposed on the displayed path, symbols indicating whether at any point on the path the radar will be able to execute each task at its respective planned repetition rate, and whether each of a plurality of areas to be surveyed by the radar, each corresponding to a respective radar task, is in the field of view pattern of the radar.

  • Patent number: 9418174
    Abstract: According to one embodiment, a computer-executed system includes a relationship identification tool coupled to one or more data storage systems and a user interface. Each data storage system has multiple data entities that are organized in at least one folder according to a particular taxonomy scheme. The relationship identification tool is operable to receive data entities from the data storage systems, and determine relationship intimacy values for each data entity relative to the other plurality of data entities according to its taxonomy scheme. These relationship intimacy values are then displayed on the user interface.

  • Patent number: 8725649
    Abstract: A system and method encrypt a license file associated with computer software using a private key. The license file includes one or more license keys, and each license key is associated with a feature of the computer software. The license file associated with the computer software is decrypted at runtime using a public key. A module determines whether a user is permitted to execute the computer software. The module is authenticated by one or more of a determination of whether a hash code included within the module matches a hash code generated by a user of the computer software at run time of the computer software, and an encryption of the module prior to run time of the computer software using the private key and a decryption of the module at run time of the computer software using the public key.

  • Patent number: 8577905
    Abstract: A method may include subscribing each of a plurality of users to receive native-format geospatial information from a data source. The method may also include receiving native-format geospatial information from the data source. The method may further include analyzing native-format geospatial information and previously-rendered geospatial data file fragments to determine whether to update one or more previously-rendered geospatial data file fragments. The method may additionally include translating native-format geospatial information into geospatial data file fragments in response to a determination to update one or more previously-rendered geospatial data file fragments, and storing such geospatial data file fragments.

  • Patent number: 7865487
    Abstract: In one embodiment, a database access system includes a remote client application, a database having a plurality of data records, and a data event agent. The database has a plurality of data records and is coupled to the data event agent. The data event agent is remotely coupled to the remote client application through a firewall and operable to receive a query from the remote client application. In response to receipt of the query, the data event agent stores the query in memory in order to continually filter additions and modifications to data records against the one or more filter criteria included in the query. In the event that a data record matches the query, the data event agent transmits the data record to the remote client application.

  • Publication number: 20100191765
    Abstract: A method for processing digital images includes receiving from one of a plurality of sensors a first image in a first format. A first set of metadata is associated with the first image. The method also includes generating a second set of metadata based on at least the first set of metadata and a configuration file. The configuration file identifies metadata to be included in the second set of metadata. Additionally, the method includes converting the first image in a first format into a second image in a second format and storing the second set of metadata in a metadata database. The method further includes receiving search parameters from clients, identifying one or more sets of metadata corresponding to the search parameters, and transmitting to a client one or more images associated with the identified sets of metadata.

  • Publication number: 20080074423
    Abstract: According to one embodiment of the invention, a method for displaying graphical objects on a digital map includes receiving, for a graphical object, metadata comprising a parameter indicating a type of the graphical object, a parameter indicating a size of the graphical object, and a group of parameters indicating a geographic location of the object represented by the graphical object. The type of the graphical object is one of a group of stored types. The method further includes rendering the graphical object on the digital map by generating, based the received metadata, a group of geographic coordinates for the graphical object.
