  • Patent number: 8976257
    Abstract: An automatic process for calibrating the optical image exposure value to compensate for changes in machine vision systems to maintain optimal exposure of captured images and adjust for the different characteristics among cameras components, such as imaging sensor sensitivity, LED strength, external lighting, reflective functions of any background material, different external lighting conditions, possible changes or updates of the systems over the years, such as LED changes, and even the aging of camera sensor and LEDs over time. A series of images of a target are captured with a predetermined sequence of exposure values, the saturation exposure percentage of a region of interest is calculated in each of the images, and the saturation exposure percentages are compared to determine the exposure value that has a saturation exposure percentage that varies the least from the saturation exposure value of the preceding and following exposure values.

  • Patent number: 8814047
    Abstract: A method for expediting the barcode interpretation process implemented on conventional optical imaging barcode readers. The method involves interrupting the mainline processing of the conventional barcode detection, obtaining a copy of the captured image, scaling the image, locating the barcode in the scaled image, scaling the image back to normal proportions, calculating the location of the barcode in the scaled up image, and reporting the barcode location back to the mainline processing for decoding of only the region of interest. The mainline processing of the optical imager may then proceed with barcode interpretation in the area identified by the method of the present invention without wasting time applying complicated decoding algorithms to areas within the image that do not contain any barcode information.

  • Patent number: 8321055
    Abstract: A machine vision system for controlling the alignment of an arm in a robotic handling system. The machine vision system includes an optical imager aligned to simultaneously capture an image that contains a view of the side of an object, such as a test tube, along with a view of the top of the object provided by a mirror appropriately positioned on the robotic arm. The machine vision system further includes a microcontroller or similar device for interpreting both portions of the image. For example, the microcontroller may be programmed to determine the location of the object in the reflected portion of the image and transpose that information into the location of the object relative to the robotic arm. The microcontroller may also be programmed to decode information positioned on the object by interpreting visual information contained in the other portion of the captured image.

  • Patent number: 7942329
    Abstract: An optical barcode and/or RFID reader having at least two sets of illuminating LEDs that are directed toward a target object to reflect whether the barcode and/or RFID reading was successful or unsuccessful. The reader is provided with a set of red LEDs and a set of green LEDs for illuminating targets, such as barcodes or RFID tags. In addition to using these LEDs to illuminate the target, the reader will illuminate the target with a particular color of light to signify a successful read, such green light, or an unsuccessful read, such as red light. A third color may be provided to indicate a successful RFID interrogation, such as blue light. The reader thus uses the built-in illumination LEDs to cast differently colored light on the target, rather than having to provide additional LEDs in a user interface positioned on the housing of the reader.

  • Patent number: 7842890
    Abstract: A one-piece housing for the enclosure and protection of an optical imager or other device and a method for locking a one-piece housing assembly in a folded configuration. The housing comprises three segments permanently joined by flexible hinges that allow the housing to quickly fold into a box to enclose an optical imager. To releasably maintain the housing in closed position, the assembly contains two locking tabs that snap-fit into depressions on a platform extending away from the main housing segment. One tab snap-fits directly into a depression on the top surface of the platform while the other tab snap-fits into a depression on the reverse surface of the platform. By locking into depressions on the top and reverse surfaces of the platform, the opposing tabs tightly grip the surfaces and releasably maintain the housing in the folded configuration.
