Abstract: A flight processor that calculates a 4-dimensional trajectory having a sequence of two or more position, time and cost (x, y, z, t, c) tuples that minimize a defined cost. Some embodiments generate cost-optimized trajectories with simple or complex constraints and bounds such as fixed AGL altitude; minimum AGL altitude; maximum AGL altitude; minimum MSL; maximum MSL; avoidance of restricted airspace; adherence to non-restricted airspace such as easements; adherence to ground-based guideways, if applicable; and the constraint to maintain adequate radio frequency signal-to-noise needed for communications to the ground station or backhaul systems.

Abstract: A center deflector for a front bumper of a truck or tractor vehicle includes a thickened portion extending upward from the inner deflector surface and extends laterally across a deflector section, preferably spanning substantially an entire width of the deflector section thereof. The thickened portion comprises a cross-sectional shape having a height that gradually declines from an intermediate maximum height to a reduced height along a rear edge thereof, and preferably resembles an airfoil. The thickened portion may include a hollow interior containing a pressurized gas.

Abstract: A system and method of vehicular wireless communication over a Dedicated Short Range Communication service band is provided. The system includes a vehicle having a navigation means, a processor, and a communication means for transmitting a message via a wireless communications link. The system includes a control channel for communication a safety communication and a service channel for communicating a non-safety communication. The control channel is subdivided into a contention-free period having a safety exchange interval of time for transmitting a safety communication and a contention period having a non-safety service interval of time for transmitting a non-safety communication. The system further includes an access point in communication with the vehicle via the communications link within region.
