A track collision avoidance control system including a train having an onboard control system for controlling one or more characteristics of the train. The track collision avoidance control system can further include a warning indication system comprising a transmitter linked to a communication system supported about the train, the communication system comprising a receiver operable to receive a signal from the transmitter, the signal comprising information pertaining to a potentially dangerous condition. The transmitter can be operable alone or in combination with a warning indicator, an actuator and their associated logic circuitry, such that the transmitter is caused to transmit upon the warning indicator being activated. The communication system can interface with an onboard control system of the train. The communication system can receive the signal, which can be used to facilitate an avoidance action to be taken relative to the train.

A system and method for providing DTN services to legacy applications is provided. According to one example, a method for providing delay tolerant networking (DTN) services to legacy applications includes acts of intercepting a packet addressed to a software application, the packet including a payload, the software application being resident on a first computer, determining suitability of the packet for DTN processing and encoding the payload into a DTN bundle. According to another example, a system for providing delay tolerant networking (DTN) services to legacy applications includes a network interface, a memory and a controller coupled to the network interface and the memory. In this example, the controller is configured to intercept a packet addressed to a software application, the packet including a payload, the software application being resident on a computer, determine suitability of the packet for DTN processing and encode the payload into a DTN bundle.

Automatic invocation of DTN bundle protocol

An apparatus for map zooming includes instructions stored in a memory that when executed by a processor render a zoom bar. The zoom bar includes a plurality of map scale hash marks arranged along an axis of the zoom bar and indicative of a map scale range of a geographic map. The plurality of map scale hash marks include a first map scale hash mark representative of a first map scale, a second map scale hash mark offset along the zoom bar axis from the first map scale hash mark and representative of a second map scale, and a map transformation hash mark located between the first and second map scale hash marks and representative of a transformation of the geographic map from a first map data set defined with reference to the first map scale to a second map data set defined with reference to the second map scale. The zoom bar further includes a map zoom bar indicator located relative to the first and second map scale hash marks and corresponding to a current map display scale and a zoom level of the geographic map.

Methods for determining paths that satisfy a reliability requirement are generally described herein. The methods may include receiving path information. A reliability requirement is established, and paths that satisfy the reliability requirement are determined. Each path comprises nodes. Configuration of the nodes of the paths according to the reliability requirement is facilitated. A code rate may be determined that corresponds to the reliability requirement. The code rate may indicate network coding to be performed by least a subset of the nodes. The method may also include sending the code rate to the nodes of the paths.
