A vehicle information system which includes an in-vehicle system 105 and a centralized server system 120. The systems and methods include the removal of arsenic from a source by contact with either a chemically treated natural or synthetic zeolite, for example a ferric-loaded zeolite. By rotationally switching the fast and slow axes of the half-wave plate, the present invention can also expose n-phase-shifted fiber grating by the same system. Depressing the plunger pushes the sheath, via the arms, into the covered position. Various devices and methods are further provided to permit tracking and reporting of disinfection events. Several slit embodiments suitable for producing edge-to-face engagement support and precise bending are disclosed, as is the use of the slit sheets to produce various three-dimensional structures and to enhance various design and fabrication techniques.
