Abstract:
1. An arrangement for minimizing misdecodes of GS 1 DataBar Limited (Databar-limited) symbols in a reader for electro-optically reading symbols of different symbologies, comprising: a data capture assembly for capturing light from a target symbol, and for generating an electrical signal indicative of the captured light; a controller for processing and decoding the electrical signal, for determining whether the decoded signal is indicative of a Databar-limited symbol, and for determining in the event that the decoded signal is indicative of the Databar-limited symbol whether the decoded signal has characteristics indicative of a fragment of a Universal Product Code (UPC) Version A (UPC-A) symbol, and for performing in the event that the decoded signal is indicative of a fragment of a UPC-A symbol at least one additional operation including one of (1) determining whether a context is compatible with a UPC-A symbol and (2) repeating decoding of the same target symbol at least one more time, wherein said repeating decoding of the same target symbol includes capturing light from the same target symbol and decoding the electrical signal generated from the captured light of the same target symbol.
