| 20090084851 | Imaging reader for and method of improving visibility of aiming pattern - An aiming light assembly supported by a mobile imaging reader projects an aiming light pattern on a symbol. A controller modulates the aiming light pattern to render the aiming light pattern more visibly discernible to an operator, especially in a brightly lit ambient environment, to enable the operator to position the aiming light pattern on the symbol prior to reading. | 04-02-2009 |
| 20100019041 | Arrangement for and method of guiding an operator to move an imaging reader to an optimum reading position - An operator is guided to move an imaging reader to an optimum reading position in which to read a symbol by image capture. Optimum image capture occurs substantially at an imaging plane of an imaging assembly, and the operator is visually guided so that the symbol is located substantially at the imaging plane in a working range of distances. | 01-28-2010 |
| 20100078481 | Imaging reader and method with enhanced aiming pattern detection - An image capture system for, and a method of, reading an optical code during a reading mode, comprise an aiming assembly including a laser for emitting a laser beam having a variable intensity, and for generating an aiming pattern from the laser beam during an aiming mode prior to the reading mode, and an imager for detecting and capturing an image of the aiming pattern and the code over a field of view by exposure over an exposure time period during the aiming mode, and for detecting and capturing an image of the code over the field of view during the reading mode. A controller is operative for controlling the intensity of the laser beam during the aiming mode by increasing the intensity of the laser beam during the exposure time period to enhance detection and capture of the aiming pattern by the imager, and by decreasing the intensity of the laser beam frame outside the exposure time period for user safety. | 04-01-2010 |
| 20100130266 | Device and Method for Battery Life Management Using Global or Local Positioning System - A device includes a memory, a wireless transceiver and a positioning system. The memory stores a first area in which a wireless network lacks coverage. The wireless transceiver is adapted to communicate with the wireless network. The positioning system determines a position of the device to determine whether the device is located within the first area. The wireless transceiver does not attempt to communicate with the wireless network if the positioning system determines that the device is located within the first area. | 05-27-2010 |
| 20100163625 | Minimizing misdecodes in electro-optical readers - An arrangement for, and a method of, minimizing misdecodes of GS1 DataBar Limited (Databar-limited) symbols in a reader for electro-optically reading symbols of different symbologies, such as Universal Product Code (UPC) Version A (UPC-A) symbols, includes a data capture assembly for capturing light from a target symbol, and for generating an electrical signal indicative of the captured light; and a controller for processing and decoding the electrical signal, and for determining whether the decoded signal is indicative of a Databar-limited symbol, and for determining whether the decoded signal has characteristics indicative of a different symbology, such as the UPC-A symbol, to indicate whether a misdecode of the Databar-limited symbol has occurred. | 07-01-2010 |
| 20110049242 | METHOD AND APPARATUS FOR ESTIMATING EXPOSURE TIME FOR IMAGING-BASED BARCODE SCANNERS - A method and apparatus for estimating an optimized exposure time for an imaging-based barcode scanner. The method includes (1) determining a SNR decodability function that enables a decodability value be determined from a signal-to-noise ratio; (2) determining a blur decodability function that enables a decodability value be determined from a blur value; (3) measuring a blur and a signal-to-noise ratio for an image captured with a first exposure time; and (4) determining an optimized exposure time based on the measured blur, the measured signal-to-noise ratio, and a combined decodability function that depends upon both the SNR decodability function and the blur decodability function. | 03-03-2011 |
| 20110073657 | METHOD AND APPARATUS FOR DETECTING A BARCODE - A method and apparatus for detecting a barcode like region contained in a target object. The method includes capturing an image of the target object, calculating a total confidence value for the captured image, and determining a presence of a barcode in the captured image based on the total confidence value, wherein the total confidence value is calculated as a function of at least one of a first, second, and third confidence values. The method of calculating the confidence values includes calculating the first confidence value based on a vertical projection signal of the barcode like region in the captured image, the second confidence value based on a horizontal projection signal of the barcode like region in the captured image, and the third confidence value based on a start and stop pattern of the barcode like region in the captured image. | 03-31-2011 |
| 20110101099 | METHOD AND APPARATUS FOR MONITORING AN EXIT WINDOW OF A SCANNER - A method, system, and apparatus for monitoring an exit window of a scanner using a plurality of imaging devices. The method includes capturing a first image through the exit window using a first imaging device, capturing a second image through the exit window using a second different imaging device, and detecting at least one of a plurality of features in both the first and second images. The method further includes matching the plurality of features detected in both the first and the second images, determining whether the at least one matched feature is present on the plane of the exit window, and monitoring a physical condition of the exit window based on the at least one feature. | 05-05-2011 |
