  • Patent number: 8976030
    Abstract: A checkout system is provided for carrying out a two-factor authentication process where coded products are purchased and theft activity might be pursued. The system typically includes an identification code reader for reading product identification codes (e.g. UPC bar code symbols or EPC-encoded RFID tags) on products that are passed through the point of sale (POS) and a security code detector/reader for automatically detecting/reading a security code (e.g. implemented as an EAS tag or an RFID tag) at the POS. During product checkout operations, the identification code reader reads identification codes, and the security code detector/reader detects or reads security codes applied to products. Collected identification and security data is automatically processed using identification and security data stored in a database to determine whether or not each product being purchased at the POS is in compliance or not in compliance with a two-factor authentication process supported by the checkout system.

  • Patent number: 8950678
    Abstract: 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.

  • Publication number: 20150014416
    Abstract: An image capture and processing system supports a multi-tier modular software, and plug-in extendable, architecture. The image capture and processing system can be realized as an image-capturing cell phone, a digital camera, a video camera, mobile computing terminal and portable data terminal (PDT), provided with suitable hardware platform, communication protocols and user interfaces. A third-party customer can write and install a software plug-in into the application layer so as to enhance or modify the behavior of the image capture and processing system without any required knowledge of the hardware platform, communication protocols and/or user interfaces.
