    Abstract: An automatic automatically-triggered digital video-imaging based code symbol reading system for use in point of sale (POS) environments, employing an adaptive control process involving the real-time analysis of the exposure quality of captured frames of digital image data and the real-time reconfiguration of system control parameters (SCPs) based on the results of such exposure quality analysis. By virtue of the present invention, the system enables the reliable reading of code symbols graphically represented in digital images, under demanding point-of-sale lighting conditions and other challenging environments.

    Abstract: A laser power control arrangement and method in an electro-optical reader for reading indicia includes an energizable laser for emitting a laser beam having an output power along a path. An internal light detector, e.g., a monitor photodiode, is mounted inside the laser for monitoring the output power of the laser. An external light detector, e.g., an auxiliary photodiode, is mounted outside the laser for monitoring the output power of the laser independently of the internal light detector. A guide, advantageously a light pipe or a diffuser, is positioned outside the laser in the path of the laser beam for guiding the laser beam from the laser to the external light detector. A controller is operatively connected to each light detector, for controlling a monitored output power of the laser beam by deenergizing the laser when the monitored output power of the laser beam exceeds a safe power level limit.

    Abstract: A stop motion sensor supported by a mobile electro-optical reader is operative for sensing when the mobile reader is supported in a steady state by the operator for a predetermined time period, and for automatically actuating the mobile reader in response to sensing the steady state to initiate reading of indicia while the mobile reader is supported in the steady state by the operator for the predetermined time period.
