摘要： A decodable indicia reading terminal can comprise a multiple pixel image sensor, an imaging lens configured to focus an image of decodable indicia on the image sensor, an analog-to-digital (A/D) converter configured to convert an analog signal read out of the image sensor into a digital signal, a communication interface, and a microprocessor configured to output decoded message data corresponding to the decodable indicia by processing the digital signal. The decodable indicia reading terminal can be configured, responsive to a triggering event, to transmit via the communication interface a decoding result and an indicia readability rating. The triggering event can be provided by a failure to detect decodable indicia, the indicia readability rating being less than a pre-defined threshold, exceeding a pre-defined time period to decode decodable indicia, a user interface action, and a command received via said communication interface.

摘要： A method and system for reading code symbols using a code symbol reading system having a programmable decode time-window filter mode of operation. During this mode of operation, only decoded code symbols that have been scanned within a selected (e.g. central) portion of the laser scan line field are processed according to a special decode time-window filtering function. In particular, if the decoded bar code symbol is a programming-type bar code symbol, then the system controller applies the function represented by the programming-type bar code symbol; and if the decoded bar code symbol is a non-programming-type bar code symbol, then the system controller either transmits symbol character data associated therewith to the host system or stores the symbol character data within memory aboard the bar code symbol reading system.

摘要： A retail information network includes one or more POS scanning and checkout systems, each including (i) a bar code symbol reading subsystem, and (ii) a cash register computer subsystem interfaced with the bar code symbol reading subsystem and a network infrastructure, and each having access to product and price data maintained in a product/price database. The bar code symbol reading subsystem includes a local predictive error event (PEE) data store for logging and storing predictive error events (PEEs) detected within the bar code symbol reading system, wherein said PEEs are subsequently sent to POS information servers used to create predictive error alerts (PEAs) and corresponding instructions to maintain and/or repair certain aspects of the bar code symbol reading system.

摘要： A laser scanning symbol reading system includes an analog scan data signal processor for producing digital data signals, wherein during each scanning cycle, a light collection and photo-detection module generates an analog scan data signal corresponding to a laser scanned symbol, a multi-channel parallel scan data signal processor/digitizer processes the analog scan data signal along multiple cascaded multi-stage signal processing channels, to generate digital data signals corresponding thereto, while a synchronized digital gain control module automatically processes the digital data signals in response to start of scan (SOS) signals generated by a SOS detector. Each signal processing channel supports different stages of amplification and filtering using a different set of band-pass filtering and gain parameters in each channel, to produce multiple digital first derivative data signals, and/or multiple digital scan data intensity data signals, having different signal amplitudes and dynamic range characteristics for use in decode processing.

摘要： A hybrid-type bi-optical bar code symbol reading system has a vertical housing section with a vertical scanning window and a horizontal housing section with a horizontal scanning window from which laser scanning planes are projected and intersect within a 3D scanning volume defined between the vertical and horizontal scanning windows. An automatic object edge-motion detection subsystem is provided for detecting the entry and exit of objects at the edge of the 3D scanning volume and generating control signals in response thereto. A digital imaging subsystem is supported within the system housing and automatically projects a field of view (FOV) within the 3D scanning volume in response to control signals generated by the automatic object edge-motion detection subsystem and timer settings managed by a system controller.
