Abstract: Systems and methods are provided for analyzing particulates. A liquid having a plurality of particulates substantially linearly ordered in a streamline can be externally controlled to provide flow in first and second directions, where, generally, the first direction is opposite to the second direction.

The flow direction can be reversed and measured at the measurement area while flowing in the second direction. The particulates substantially retain the same linear order during at least one cycle, a cycle being defined by movement in the first direction followed by movement in the second direction.

Abstract: Techniques and systems for decoding optical codes using symbol-based algorithms are described. In one example, a method includes acquiring a signal representative of light reflected from an optical code comprising one or more symbols of a finite set of symbols and applying a decoding model to the signal. The decoding model may relate measured signals to the finite set of symbols, such that each of the symbols of the finite set of symbols are associated with a respective encoded character of a finite set of encoded characters. The method may also include determining, by a processor, a sequence of one or more of the encoded characters based on the application of the decoding model to the signal. In this manner, the optical code may be decoded by directly fitting an acquired signal from the optical code to possible symbols within the optical code and the associated encoded characters.
