Abstract: A method and apparatus for associating received pulses with one of a plurality of emitters emitting pulses at periodic intervals. Periodic pulse trains are detected by computing the difference in arrival times between each received pulse and a fixed number of previously received pulses. In the simplest embodiment, a periodic pulse train is detected when one of the computed differences is one-half of another computed difference. In other embodiments, further processing is performed to detect staggered pulse trains or other periodic patterns.

Abstract: An enclosure for the end opening of a vehicle having one or more interior elevated decks includes a pair of door assemblies each comprising a plurality of pivotally joined panels. The door assemblies are suspended in a vertical manner by means of hanger assemblies having tracking elements guided within a rail member disposed above the level of a vehicle elevated deck. Transverse movement of any panel concurrently displaces the entire associated door assembly, as a unitary articulated assembly, between a closed position sealing off the end opening, and an open position with the door assembly well-spaced from a lateral edge of the deck, in which latter position maximum lateral clearance is provided for lading carried by all decks or levels. With the vehicle provided with a raised top section or pitched roof, an enclosure is obtained for the upper portion of the end opening by the inclusion of inwardly directed top panel sections extending above each of the panels and which substantially conform to the pitch of the adjacent roof section when the door assembly is disposed in the open position.
