Systems, methods, and apparatuses for high-speed navigation. The present invention preferably encompasses systems, methods, and apparatuses that provide for autonomous high-speed navigation of terrain by an un-manned robot. By preferably employing a pre-planned route, path, and speed; extensive sensor-based information collection about the local environment; and information about vehicle pose, the robots of the present invention evaluate the relative cost of various potential paths and thus arrive at a path to traverse the environment. The information collection about the local environment allows the robot to evaluate terrain and to identify any obstacles that may be encountered. The robots of the present invention thus employ map-based data fusion in which sensor information is incorporated into a cost map, which is preferably a rectilinear grid aligned with the world coordinate system and is centered on the vehicle. The cost map is a specific map type that represents the traversability of a particular environmental area using a numeric value. The planned path and route provide information that further allows the robot to orient sensors to preferentially scan the areas of the environment where the robot will likely travel, thereby reducing the computational load placed onto the system. The computational ability of the system is further improved by using map-based syntax between various data processing modules of the present invention. By using a common set of carefully defined data types as syntax for communication, it is possible to identify new features for either path or map processing quickly and efficiently.

An apparatus and methods for balancing current in multiple negative impedance gas discharge lamp loads. Embodiments advantageously include balancing transformer configurations that are relatively cost-effective, reliable, efficient, and good performing. Embodiments include configurations that are applicable to any number of gas discharge tubes, such as cold cathode fluorescent lamps. The balancing transformer configuration techniques permit a relatively small number of power inverters, such as one power inverter, to power multiple lamps in parallel. One embodiment of a balancing transformer includes a safety winding which can be used to protect the balancing transformer in the event of a lamp failure and can be used to provide an indication of a failed lamp.

A SONET network terminated by routers includes working paths and backup paths. The routers pre-establishes in their link state data bases the links in both for both the working and backup paths. However, the links involved in the backup paths are given higher costs, then the links working paths, that the routers select only the links in the working path. If there is a failure in a link in a working path, an APS arrangement provides rapid switchover of the optical links so as to substitute one or more links in the corresponding backup path. This is accomplished by changing the relative costs of the working and backup links involved, so that the routers select the backup links for their routing tables.

A fault management system is directed to the access network part of a communications network where terminating lines in the form of pairs of copper wires extend from a local switch through a series of nodes to terminal equipment provided for user of the network. Each night, a test head performs a series of tests on each of the terminating lines. The results of the tests are transmitted to an access network management system where they are analyzed with respect to a set of parameters to identify characteristics that would indicate that a fault is likely to occur on the associated circuit within a predetermined period e.g. 1 year. Further analysis can then be carried out to establish the probability of the fault actually occurring and/or whether the potential fault analyzed is going to occur in either the underground or the over-ground part of the network. Further analysis determines relative costs of repair for circuits or network elements in which faults or potential faults have been identified.

A system and method for performing content aware cropping or expansion may be applied to translate an object within an image. The object may be selected by defining an approximate bounding box of the object. The method may receive input indicating a lowest priority edge or corner of the object to be translated (e.g., using a drag operation). Respective energy values for pixels in regions of the image adjacent to a region comprising the selected object may be weighted based on their distance from the region and/or lowest priority edge/corner, on a cropping or expansion graph, and/or on the translation dimension and direction. Relative costs may be determined for seams of these regions dependent on the energy values. Low cost seams may be removed from one region and replicated in another region, and the region comprising the translated object may be combined with these resized regions in a modified image.

In a communications network, each network node includes a first module that handles a group of channels between its input and output ports as a route decision unit and a second module that handles a channel between its input and output ports as a route decision unit. A module state database stores module cost data of the first and second modules and a link state database stores link cost data of the links. Using the module and link state databases a route of minimum cost is determined and a connection is established between an incoming link and one of the input ports of the first and second modules and a connection is established between one of the output ports of the first and second modules and an outgoing link. The contents of the module and state databases are broadcast to the network.
