A novel and useful acquisition and synchronization mechanism for spread spectrum communication systems whereby a synchronization sequence comprising a plurality of known symbols spaced apart by predefined time delay intervals is transmitted as the start of packet signal. The composite canopy halves, when assembled into a spray booth additionally including either a floor or a utility base and one or a pair of end units in the form of aperture bulkheads, vestibules, or a combination of both, are structurally sufficiently strong that no external support frame is required. The monitor circuit can detect a change of decrease of a potential difference between the pair of power source wires. The opinion rating and the user identification are added to a database and the data in the database is used to calculate a reputation for the container. This assembly is lowered into the borehole on the pipe string. If the midpoint wavelength is greater than the decision threshold wavelength, the presence of ice is indicated on the surface.
