  • KILLSWITCH ARRANGEMENT FOR AND METHOD OF REGULATING LASER OUTPUT POWER IN ELECTRO-OPTICAL READERS
    Publication number: 20140126594
    Abstract: Output power of a laser beam emitted by a laser in an electro-optical reader is regulated by storing a killswitch byte in non-volatile memory, and by checking whether the killswitch byte is in a default state or a kill state prior to performing reading. A controller detects a fault condition and responsively changes the killswitch byte to the kill state, in order to permanently deenergize the laser and to maintain the laser permanently deenergized after the killswitch byte has been changed to the kill state.

  • NON-ECHO ULTRASONIC DOPPLER FOR CORRECTED INERTIAL NAVIGATION
    Publication number: 20140121961
    Abstract: A method and device for non-echo ultrasonic Doppler used for corrected inertial navigation includes providing at least one ultrasonic emitter within an environment, each emitter configured for transmitting an ultrasonic tone of a predefined frequency. An initial location of the mobile device is established within the environment. Dead reckoning procedures are initiated using sensors within the mobile device. The device receives at least one ultrasonic tone from an emitter, and converts the at least one ultrasonic tone into a digital waveform. The device determines at least one peak frequency of the digital waveform, and subtracts the at least one peak frequency from each predefined frequency to determine at least one Doppler shift, which is used for correcting the dead reckoning of the mobile device.

  • 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.

    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.
