Logistics system and method

A logistics method is disclosed that provides logistics computer programming for controlling a plurality of transports to supply a plurality of delivery locations from one or more bases. Each of the bases and delivery locations are in communication with a central database, preferably an Internet server database, that contains updated logistics information. The central database is preferably automatically updated at selectable intervals as to transport location, destination, fuel level, speed, and heading. Manifests may be originated at the respective delivery location or at an associated base and are stored in the central database. Each material on the manifest is associated with information such as the authorized vendor, a description, storage preferences, units, hazardous designations and additional information if the material is hazardous. Given information about each transport such as load capacity, fuel level, location intelligence, and the like that is stored in the central database and information about the materials, manifest status, and other factors, potential least cost delivery routes using capable transports can be automatically produced for selection by an operator. The logistics computer programming automatically designates where each manifested material is stored on the transport. The computer programming associates a status designation with each manifest such as outstanding, staged, printed, loaded, unloaded, and cancelled. Each manifest is also associated with a priority which may range from emergency to routine. Updated logistics information concerning materials, manifests, vendors, transports, delivery locations, and operating companies is available from the central database.

Microwave signal phase shifting method based on polarized light interference technique

The invention discloses a microwave signal phase shifting method based on polarized light interference technique in the technical field of microwave photonics. Photonic microwave signals generated by modulating a single sideband are transmitted by a polarization maintaining fiber and generate a group of optical carrier with locked phase and vertical polarization in a polarization manner by using the high birefringence characteristics and an appointed fusion angle. The input vertically-polarized optical carriers can generate different phase shift under the bias voltage of a phase modulator according to the polarization relativity of the modulation efficiency of the phase modulator, so that the phase difference among the optical carriers can be changed by adjusting the bias voltage. Then, the optical carriers are received by an analyzer with an appointed polarization angle to generate a group of parallel-polarized phase-shifting optical carriers. A photoelectrical detector can generate an electrical domain microwave phase-shifting signals after receiving beat frequency and isolating DC components, wherein the phase shifting magnitude depends on the bias voltage of the phase modulator. The invention further lowers the complexity of the microwave phase shifting system, and improves the phase shifting accuracy.
