A system and method are disclosed for computing a vehicle's motion in four dimensions (e.g., three spatial dimensions and time) and reliably predicting the vehicle's arrival time at a predetermined location, by providing a graphical display to an operator of the vehicle's progress that enables the operator to adjust the vehicle's movement and achieve the desired arrival time. Specifically, a system and method are disclosed for computing the movement of an aircraft in four dimensions, predicting its arrival time at a predetermined waypoint, and displaying (in a highly intuitive format) the aircraft's progress in achieving that desired arrival time. The pilot can then adjust the movement (e.g., speed) of the aircraft in accordance with the parameter(s) displayed, in order to achieve the desired arrival time. Thus, for example, numerous aircraft could be scheduled to arrive at a specific final approach waypoint at a predetermined rate (e.g., one aircraft per minute), which would enable the traffic controllers to optimize runway traffic without having to stack the aircraft in holding patterns and thereby waste fuel. Notably, although an example of an aircraft navigation and control system and method is disclosed, the system and method can be implemented for any type of vehicle (e.g., aircraft, spacecraft, ship, submarine, bus, train, automobile, etc.) whose operator desires to reach a particular location at a specified time.

Methods and apparatus for providing an Anti-Flooding Flow-Control (AFFC) mechanism suitable for use in defending against flooding network Denial-of-Service (N-DoS) attacks is described. Features of the AFFC mechanism include (1) traffic baseline generation, (2) dynamic buffer management, (3) packet scheduling, and (4) optional early traffic regulation. Baseline statistics on the flow rates for flows of data corresponding to different classes of packets are generated. When a router senses congestion, it activates the AFFC mechanism of the present invention. Traffic flows are classified. Elastic traffic is examined to determine if it is responsive to flow control signals. Flows of non-responsive elastic traffic is dropped. The remaining flows are compared to corresponding class baseline flow rates. Flows exceeding the baseline flow rates are subject to forced flow rate reductions, e.g., dropping of packets.

A safety net that includes at least one illuminating element. The safety net is intended to be stored in a rolled-up fashion (similar to a roll-up window shade) in the trunk of a vehicle. When illuminated, the safety net provides a completely new and unique means of alerting oncoming traffic to a road hazard or other situation requiring traffic control. The safety net provides a warning means that will not be knocked over by the wind, as wind blows freely through the voids of the net. In addition, the safety net screens the scene from the view of those in oncoming traffic. The device may include a solid state controller that provides a variety of patterns or symbols to further enhance the visual safety features of the device. This can be accomplished by placing fiber optic strands in the net voids, or within the side illuminating fiber optic conduit itself. The device may also include metal cables to form a physical barrier.

A method and a system for assisting air traffic controllers that automatically detects conflicts between aircraft trajectories and selects the conflicts that can be solved by minor modification(s) of aircraft speed, climbing rates or descending rates and lateral shifts of route. Minor modifications are selected so as to not interfere with current controllers' decision making process thereby circumventing the basic rule of uniqueness of control in a given piece of airspace. The minor modifications are automatically transmitted to aircraft for execution without requiring controllers' prior agreement. Thus, the method solves most conflicts, such that the air traffic delivered to the controllers is free of most of the pre-existing conflicts.
