  • Apparatus for and method of electro-optically reading direct part marking indicia by image capture
    Patent number: 8690063
    Abstract: An apparatus and method electro-optically read indicia, such as a direct part marking (DPM) code, that is raised or sunken relative to a target surface on a target. A solid-state, distance imaging sensor captures a target image comprised of a first set of pixels having first distance values that correspond to a first distance of the code from the sensor, and a second set of pixels having second distance values that correspond to a second distance of the target surface from the sensor. A controller reads the indicia by distinguishing between the first set of pixels and the second set of pixels within the image, by determining abrupt changes in the distance values among neighboring pixels.

  • ARRANGEMENT FOR AND METHOD OF MANAGING A SOFT KEYBOARD ON A MOBILE TERMINAL CONNECTED WITH A HANDHELD ELECTRO-OPTICAL READER VIA A BLUETOOTH(R) PAIRED CONNECTION
    Publication number: 20140091147
    Abstract: A wireless Bluetooth® paired connection is established between a Bluetooth® module in an electro-optical, handheld reader and a Bluetooth® module in a mobile terminal via a human interface device (HID) profile. Data capture from a target is initiated upon one type of manual actuation, e.g., a single pull, of a trigger on the reader. A soft keyboard is caused to appear on a display on the terminal, either immediately, or after a predetermined event, after the establishment of the Bluetooth® paired connection. The soft keyboard is caused to disappear upon manual actuation of the trigger with a different type of manual actuation, e.g., a double pull, of the trigger. Another double pull of the trigger will cause the soft keyboard to reappear.

  • ARRANGEMENT FOR AND METHOD OF ALERTING A USER TO CONTEXT-BASED TRANSACTIONAL INFORMATION UNDER WHICH PRODUCTS ARE TO BE TRANSACTED AT A POINT-OF-TRANSACTION SITE
    Publication number: 20140089121
    Abstract: A user is alerted to context-based transactional information under which products are to be transacted at a point-of-transaction site by a speaker on an electro-optical reader. The speaker announces, as an audible message, to the user a detailed context under which each product identified to the reader is to be transacted. The audible message is broadcast as a sound wave either corresponding to a pattern of original speech, or to a sound effect. The detailed context can, for example, be a reminder to deactivate an electronic article surveillance (EAS) tag associated with each identified product, or a reminder that the identified product is on sale.
