摘要:
An optical reader for decoding an encoded symbol character of a symbology includes a scan data signal processor having as an input a scan data signal encoding information representative of the encoded symbol character. The scan data signal processor includes a first time delay stage adapted to provide a primary phase waveform from the scan data signal, a second time delay stage adapted to provide an early phase waveform from the scan data signal, and a third time delay stage adapted to provide a delayed phase waveform from the scan data signal. The early phase waveform has a propagation delay less than the primary phase waveform, and the delayed phase waveform has a propagation delay greater than the primary phase waveform. The scan data signal processor further includes a peak window detection stage for generating a peak window timeframe when an amplitude of the primary phase waveform is greater than, less than, or equal to both an amplitude of the early phase waveform and the delayed phase waveform. The optical reader further includes a digitizer circuit adapted to accept, within the peak window timeframe, the scan data signal processor output.

An indicia-reading system is provided that adjusts the intensity of an indicia signal to an optimal level in an efficient and timely manner. The indicia-reading system incorporates an indicia-capturing subsystem for acquiring an indicia signal, a gain adjustment subsystem, and an indicia decoding subsystem. The gain adjustment subsystem derives a plurality of derivative signals from the indicia signal. At least two of the derivative signals have different gain adjustments from one another. The indicia-decoding subsystem is configured to decode at least one of the derivative signals.

An indicia-reading module is capable of integration into the smallest face of thin-profile smart device. The module employs chip-on-board packaging and a customized sensor enclosure to eliminate the stack-up height found in conventional packaging. The module also employs a customized frame to reduce volume by integrating circuit subassembly circuit boards into a unique architecture and by serving as the lenses for the illuminator and the aimer, thereby eliminating the need for any extra lenses or holders.

Indicia-reading systems include an auxiliary reading apparatus with wireless charging capability. The systems are configured to couple, transfer, and receive energy wirelessly between a base charging station and auxiliary indicia reader via resonating coils that include an impedance matching network. Wireless charging capability can save space at the point-of-sale and add convenience for the operator.

A self-checkout shopping system improves the retail shopping experience, permitting the self-serve customer to perform checkout tasks that are typically performed at the retailer's checkout area as the customer is selecting items for purchase. The system includes a mobile computer device and an indicia reader. The customer uses the mobile computer device to scan items selected for purchase. The item numbers are then compiled onto a list of acquired merchandise. When the customer has finished shopping, the system transmits the list of acquired merchandise, and any additional information such as customer financial information, to a point-of-sale terminal to facilitate the customer's payment for the merchandise.
摘要:
A digital-imaging based code symbol reading system includes a planar laser illumination and imaging module (PLIIM) employing a 2-D image detection array to capture narrow-area 2D digital images, and then automatically processes the pixels of the narrow-area 2D digital images so as to generate composite single-column 1D digital images for decode processing. The system employs a method of capturing and processing narrow-area 2D digital images using semi-redundant sampling based pixel processing techniques, to composite single-column linear images on a 2D image detection array.
