Abstract: A knowledge-based hierarchical method for detecting regions of interests (ROIs) uses prior knowledge of the targets and the image resolution in detecting ROIs. The result produces ROIs that contain only one target that is completely enclosed within the ROI. The detected ROI can conform to the shape of the target even if the target is of irregular shape. Furthermore, the method works well with images that contain connected targets or targets broken into pieces. The method is not sensitive to contrast levels and is robust to noise. Thus, this method effectively detects ROIs in common real world imagery that has a low resolution without costly processing while providing fast and robust results.

Abstract: A method and system for detecting GPS interference is disclosed. In one exemplary embodiment, a method for detecting interference in a Global Positioning System comprises the steps of receiving at least one satellite signal from one or more satellites in a Global Positioning System; identifying a noise floor value from the at least one satellite signal; identifying an interference signal based on the noise floor value; determining an interference value for the interference signal from the noise floor value wherein a level of the noise floor value corresponds to a level of interference; and providing the interference value to at least one user for informing the user of the interference signal.

Abstract: The present invention pertains to a battery adapter that may include a battery housing. The housing may be made essentially of a substantially rigid material. This housing may be configured to hold one or more batteries. A bottom portion may be provided and may be configured to be disposed at a first end of the housing. The bottom portion may include a venting portion configured to permit the flow of gasses from within the housing to the exterior of the housing. Alternatively, the venting portion may be located anywhere on the housing. A membrane may be disposed over the venting portion. This membrane may be configured to rupture when a high pressure builds up within the housing.

Abstract: The present invention relates to an agent for distributed networking and a processor-readable software code. The agent may include, for example, a cosite analyzer, an EMI sniffer, an asset controller module, an asset discovery module, and a link negotiator. The agent may be configured to initiate and optimize network configurations for radio communications systems based on parameters. The software code may receive data associated with a network plan, may determine if any planned links are included in the network plan and may establish connectivity of a confirmed link between at least two nodes in the network. Additionally, the software code may determine if a non-planned link should be added to the network and may establish connectivity for the non-planned link based on a priority associated with the non-planned link.

Abstract: A method and apparatus for storing and updating information in a multicast system is represented by a tree data structure. The method and apparatus defines and populates a set of keys for each node in the tree. The number and content of the set of keys may vary depending on whether a node is an internal node or a leaf node. The method and apparatus can use these keys to update information in some leaves while excluding the information from other leaves. The method and apparatus can analyze the system to determine a minimum number of messages that need to be sent in order to update the information stored in leaves. The method and apparatus then sends the minimum number of messages throughout the system where each message can only be read by a particular subset set of the leaves that have the correct key to read that particular message.

Abstract: A satellite positioning system and method of maintaining the positioning and clock data of a satellite using as few as one or two monitoring stations is disclosed. Each satellite of the positioning system determines its own positioning and clock data relative to other satellites in a constellation. One or more satellite signal monitoring stations receive relative clock and positioning data from a plurality of satellites in the constellation. A constellation solution which is applicable to all of the satellites in the constellation is calculated by treating the constellation as a rigid body at a fixed point in time. The constellation solution is transmitted to a satellite of the constellation which disseminates the solution through a crosslink network within the constellation for use by each satellite to update its individual positioning and clock data as needed.

Abstract: The inventions relate to systems and methods for providing interactive media content with an easy-to-use graphical user interface. The inventions include simplifying improvements to the user interface of a networked system of servers providing advertising, games, internet, video, and other services. Improvements include a plurality of panels for the simultaneous display of a plurality of media, a promotion scheduler for controlling the content of the panels, a simplified means for making purchases, and a simplified means for navigating through layers of multiple options.
