A communications system having a data transfer pipeline apparatus for transferring data in a sequence of N stages from an origination device to a destination device. The method utilizes a non-electrical source of energy to effect the switching transformation. The method also includes spatially resolved automatic determination of confidence values for a plurality of positions on the segmentation contour using the characteristic values determined for the corresponding positions. The half with the convex shape is used to view vehicles that are close to the driver’s vehicle. Room temperature operable quantum cellular automata and qubits are constructed therefrom. In one embodiment, shared security information is stored on a local system and on a cloud computer system to allow secure communications between software applications on the two systems.
