Abstract: A system and method of aligning and calibrating sensor measurements to determine motion characteristics of a moving object. The method involves calibrating a plurality of sensors for a multi-dimensional field of interest, based on one or more of motion data of the moving object, and spatial data and timing synchronization of the plurality of sensors, to obtain first measurements. The method also includes determining initial estimate of one or more of location, velocity, spin, and spin axis of the moving object from the first measurements. It compares succeeding sets of measurements with the determined initial estimate to modify the initial estimate, wherein the succeeding set of measurements are obtained from the plurality of sensors. It then determines the motion characteristics of the moving object based on the modification of the initial estimate.

Abstract: A local area network/wide area network (LAN/WAN) switch is presented which aggregates LAN traffic onto SONET/SDH transport streams in a programmable manner. The system can concentrate Ethernet packets and map the data onto SONET streams at data rates varying from STS-1 to STS-12C. Depending on the bandwidth available in the WAN interface, different numbers and combinations of STS-n streams can be formed. The system allows for efficient and flexible mapping of LAN traffic onto a WAN for transport over fiber optic networks.
