This disclosure relates to a molecular sieve comprising a framework of tetrahedral atoms bridged by oxygen atoms, the tetrahedral atom framework being defined by a unit cell with atomic coordinates in nanometers shown in Table 3. The GPS receiver is mounted in the vehicle and measures the horizontal velocity of the vehicle as well as its attitude. This allows for realizing an atomic device which can facilitate integration of atomic circuits and reduce disturbances or the like. The invention also pertains to an apparatus that may be used to preserve the quality of a perishable product.
