    摘要: The invention relates to a microprocessor-based decoder board for an optical reader having in one embodiment a plurality of imaging modules that provide frames of image data having a plurality of formats. In one method for operating the decoder board of the invention, and a multiple imaging module reader comprising the decoder board, a frame of image data captured by a selected imaging module is decoded. The decoder board determines the format of the frame of image data from information about which of the plurality of imaging modules provided the frame of image data or from information about the frame of image data, activates as necessary a command to prepare the decoder board to decode the frame of image data according to the format provided by the imaging module, and performs the decoding.

    摘要: The invention is a system and method for providing optimized accuracy and precision in analog-to-digital conversions of data. In an embodiment of the invention, an A/D converter is configured by setting two separately definable reference voltages that are controlled by a microprocessor. The A/D converter range is as wide as, or slightly greater than, a dynamic range of the analog signal to be converted. The microprocessor adjusts at least one reference voltage. The A/D converter receives analog signals from a sensor. The dynamic range of the signal from the sensor, or the sensor operating conditions, are used to define the reference voltages. The converted data is provided to a data processor at a rate controlled by a clocking signal. In a method according to the invention, the A/D converter is operated using the features described above. The accuracy and the precision of the converted data are thereby optimized.
