| 20090084848 | Arrangement for and method of uniformly illuminating direct part markings to be imaged and electro-optically read - Performance of an imaging reader for electro-optically reading direct part markings on workpieces is enhanced by uniformly illuminating the markings. An illuminator is operative for emitting illumination light of greater and lesser intensity toward the indicia. A diffuser is operative for diffusing the illumination light en route to the indicia. The diffuser includes a plurality of diffusing elements adjacent the illuminator for diffusing the illumination light of greater intensity more than the illumination light of lesser intensity. | 04-02-2009 |
| 20090084854 | Multiple Camera Imaging-Based Bar Code Reader - A multicamera imaging-based bar code reader for imaging a target bar code on a target object features: a housing supporting a plurality of transparent windows and defining an interior region, a target object being presented to the plurality of windows for imaging a target bar code; an imaging system including a plurality of camera assemblies coupled to an image processing system, each camera assembly of the plurality of camera assemblies being positioned within the housing interior position. Each camera assembly includes a sensor array and an imaging lens assembly for focusing a field of view of the camera assembly onto the sensor array and wherein the sensor array is read out at a predetermined frame rate. The predetermined frame rate of at least one camera assembly is less than the predetermined frame rates of the other camera assemblies. | 04-02-2009 |

| 20090218403 | Arrangement for and method of accurately aiming at direct part markings prior to being imaged and electro-optically read - Aiming of an imaging reader at direct part markings (DPM) on workpieces is enhanced by emitting an aiming light beam during aiming, and by optically modifying the aiming light beam during the aiming to generate an aiming light pattern having an outer bright region illuminated by the aiming light beam and visible to an operator to enable the operator to manually position the bright region to entirely surround at least part of the DPM, and an inner dark region not illuminated by the aiming light beam and surrounded by the bright region. The dark region contains the part of the DPM code to be imaged and read by the reader after the aiming. | 09-03-2009 |

| 20100138557 | Method and Apparatus For Implementing Alerts on a Browser Running on a Portable Handheld Device - A method and apparatus for implementing alerts on a browser running on a portable handheld device is disclosed. The method generates an asynchronous notification action from the server and in response transmits an alert containing a message indicating availability of HTML pages that describe the nature of the alert. The alert is received at a node on a network and translated into the original message. An alert receipt acknowledgment is transmitted to the server. Access to the alert HTML page is provided through a URL containing the appropriate query strings necessary to present the appropriate HTML page. The invention also discloses a wireless local area network (WLAN) adapter associated with a wireless network that receives paging signals from a server on the network and returns an acknowledgment signal back to the server. The invention also discloses a client/server based method of delivering messages initiated by a client. After a connection is established between a client and server, the client requests a message from the server. In response, the server retrieves and returns the message back to the client. | 06-03-2010 |
| 20100237150 | POINT-OF-TRANSACTION WORKSTATION FOR ELECTRO-OPTICALLY READING ONE-DIMENSIONAL AND TWO-DIMENSIONAL INDICIA BY IMAGE CAPTURE - A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation. | 09-23-2010 |
| 20110121077 | INCREASING IMAGING QUALITY OF A BAR CODE READER - The exemplary system requires a 2D barcode be located on an object, a portion of which is to be captured in an image. The module size of the 2D barcode is chosen to match the smallest feature to be preserved on the output image. While the target is moving with respect to the imager the 2D bar code is also moving and the resulting image is degraded. The imager will properly decode the 2D barcode only if the bar code is stationary (or moving very slowly) and hence will provide an acceptable image in the region of the 2D bar code. | 05-26-2011 |
| 20110127335 | IMAGING-BASED SCANNER INCLUDING BORDER SEARCHING FOR IMAGE ACQUISITION - A method utilizing an imaging-based bar code reader to identify a desired acquisition area within a captured image frame, the desired acquisition area including a target bar code and an extent of the desired acquisition area bounded by a border featuring: identifying a region of the captured image frame corresponding to an image of the target bar code; determining a reference point within the imaged target bar code; determining a reference point within an image of the desired acquisition area; searching for an image of the border of the desired acquisition area; identifying the imaged border of the desired acquisition area; and saving in memory a portion of the captured image frame corresponding to an image within the imaged border. | 06-02-2011 |
