Abstract
Abstract A monitoring system, particularly for use with document sorting apparatus, comprises a sensor assembly including a sensor (33) for sensing a respective characteristic of an article and for generating a corresponding first output signal, and a detector controller (42) for applying at least one of a predetermined set of algorithms to the first output signal from the sensor (33), in conjunction with data supplied to the detector controller (42), to generate one or more second output signals. A detector processor (41) common to each of the sensor assemblies supplies the data and algorithm selection information to the detector controllers (42) to control which of the set of algorithms is applied by the detector controller (42) and to generate in response to the or each second output signal and reference data a third output signal representative of the characteristic of the article being monitored.
