A code reading system capable of signaling exception handling procedures for products being handled in a work environment, such as, for example, consumer product being purchased in a retail store or a product or package being sorted by a logistics company. The system includes a system housing containing one or more one or more signal sources for generating distinctive visual and/or audible exception handling signals for special classes of products identified in the environment. Such special products may include: EAS tagged products requiring EAS tag deactivation: alcohol and tobacco products requiring proof of age; controlled products requiring additional customer tracking; age restricted products requiring identification; product purchases requiring personnel to show up and approve or assist in a product transaction; and the like.

The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

A portable adapter that provides non-repudiable telecommunications services to bar-code reading hand-held computers and palm-top or tablet-type mobile computers is disclosed. The adapter provides supplemental power supply and processing capacity that supports API communications functions, such as interactive voice recognition, conference calling, data encryption, VoIP packetization and other signal-format conversions that are not implemented on mobile computers. In particular, the device automatically logs IP packet identifiers and DOV dialing and status signals, without the user having access to edit this information, thereby providing a "non-repudiation" record of all communications. The adapter also supports intensive use of the host computer's serial port by supplementing the power available from the host computer's battery, or replacing that battery with a connector. For plant inspection and inventory auditing, ground-based cellular communications are implemented for supporting on-site work, including conference calling to discuss apparent pilferage or imminent safety hazards, and removable WORM recording media for documenting these discussions. For repair shop use, a standard phone jack or 10-base-T connector allows the device to upload engine test-data, with reports or estimates dictated by the mechanic to the repair shop's LAN server. For hospital use, the device includes removable WORM media for logging patient test results and examination reports. The hospital device also uses a dedicated local-area RF or IR transmitter, with location-specific encryption, to protect the privacy of lab reports received by the device, and to limit use of these devices to hospital's own premises.

An optical code reading system having an auto-exposure system for use with a variable resolution imaging sensor in which very low resolution images are used to determine exposure parameters is presented. The very low resolution images can be transferred much faster than high resolution images which results in a very fast auto-exposure system. The optical code reading system further includes an optical zoom system for zooming in and out of a target without the use of any moveable components. The optical zoom system makes use of a binning and/or subsampling feature of the imaging sensor for zooming in and out of the target. High-speed decoding methodologies are also presented for the optical code reading system. One decoding methodology utilizes low resolution images for performing high-speed decoding. Other methodologies utilize low resolution images and higher resolution images, if the optical code imaged by the low resolution images is not decoded successfully.

An optical code reading system and method are provided for reading and decoding an optical code. The system includes a plurality of light sources, a color image sensor, a processor and a decoder. Each light source produces a unique wavelength/color of light to illuminate the optical code, such as a direct mark optical code. The image sensor detects the reflected light from the optical code and generates an integrated multi-colored image. The processor separates the integrated image into individual color channels, where each color channel includes data representative of the imaged optical code in one color. The processor analyzes the contrast for each color channel and determines which color channel has the optimum contrast. The data corresponding to the color channel having the optimum contrast is then decoded by a decoder.
