  • OBJECT DETECTING SYSTEM FOR IMAGING-BASED BARCODE READERS
    Publication number: 20140097337
    Abstract: An apparatus includes a light emitting diode operative to emit mostly invisible light within an invisible bandwidth, and a scattering surface configured to scatter a first portion of the invisible light from the light emitting diode out of the window. The scattering surface is also partially transparent to allow a second portion of the invisible light from the light emitting diode to pass through the scattering surface and strike the reflector that is configured to reflect at least some of the second portion of the invisible light towards the window. The apparatus further includes a photodetector configured to detect returned invisible light from the target object.

  • 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 PREVENTING OVERHANGING WEIGHING PLATTER OF SCALE FROM TIPPING AT PRODUCT CHECKOUT SYSTEM AND METHOD OF MOUNTING AND REMOVING THE WEIGHING PLATTER WITHOUT TOOLS
    Publication number: 20140090902
    Abstract: A checkout system includes a workstation having a data capture arrangement for capturing through a horizontal window a target associated with a product to identify the product being checked out at the workstation, and a scale for weighing the product at the workstation. The scale has a scale mechanism, and a weighing platter on which the product is placed for weighing. The weighing platter is integrated with the horizontal window and overlies the scale mechanism. The weighing platter projects past the scale mechanism and has a front end that overhangs the scale mechanism. Non-threaded, interlocking connectors, which are provided on the weighing platter and the scale mechanism, prevent the weighing platter from tipping if a force is exerted on the front end of the weighing platter. The weighing platter is mounted on, and removed from, the scale mechanism without the aid of tools.

  • 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.

    Publication number: 20140084050
    Abstract: A method and system for locationing of a mobile device (100) within an environment includes light sources (116) disposed within the environment and modified to provide a plurality of unique identity patterns (202) associated with particular locations within the environment. A camera (106) and image processor (102) of the mobile device can obtain images of a modified light source (200) and recognize the unique identity patterns in the image and a horizontal and vertical angle of a position of the light source in the image from a center position. An accelerometer (300) can capture the gravity vectors of the camera. A locationing engine (102, 130) can determine a location of the mobile device using the unique optical pattern, gravity vectors, and the horizontal and vertical angles.

  • 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.
