  • Patent number: 9659200
    Abstract: A scanning code symbol reading system includes an analog scan data signal processor for producing digitized data signals, wherein during each laser beam scanning cycle, a light collection and photo-detection module generates an analog scan data signal corresponding to a laser scanned code symbol, an analog scan data signal processor/digitizer processes the analog scan data signal to generate digital data signals corresponding thereto, and a synchronized digital gain control module automatically processes the digitized data signals in response to start of scan (SOS) signals generated by a SOS detector. The synchronized digital gain control module generates digital control data which is transmitted to the analog scan data signal processor for use in controlling the gain of a signal processing stage in the light collection and photo-detection module and/or analog scan data signal processor, during the corresponding laser beam scanning cycle.

  • Publication number: 20170116449
    Abstract: An image capture and processing system supports a multi-tier modular software, and plug-in extendable, architecture. The image capture and processing system can be realized as an image-capturing cell phone, a digital camera, a video camera, mobile computing terminal and portable data terminal (PDT), provided with suitable hardware platform, communication protocols and user interfaces. A third-party customer can write and install a software plug-in into the application layer so as to enhance or modify the behavior of the image capture and processing system without any required knowledge of the hardware platform, communication protocols and/or user interfaces.

    Abstract: An illumination control process for use in a digital image capture and processing system includes illuminating an object in the field of view with different pulses of illumination over a pair of image frames, detecting digital images of the illuminated object over these image frames, and decode processing the digital images. In an embodiment, upon failure to read a symbol in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the exposure time is adjusted during subsequent image frames. In another embodiment, upon failure to read a symbol in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the energy level of the illumination is adjusted during subsequent image frames.

    Abstract: There is set forth herein an indicia reading terminal having data format conversion capabilities. The indicia reading terminal includes an image sensor integrated circuit with an image sensor array comprising a plurality of pixels. The image sensor integrated circuit is configured to output image data in a first data format to a data formatting circuit for conversion to image data in a second data format. The data formatting circuit is configured to provide the image data in the second data format to the at least one data interface of a microprocessor integrated circuit, which is operative to transfer image data received by the at least one data interface into memory of the indicia reading terminal. A CPU of the microprocessor integrated circuit is operative for executing a decoding algorithm for processing image data in the memory for attempting to decode at least one symbol represented in the memory.

  • Patent number: 9104930
    Abstract: An optical code symbol reading system includes a housing having a light transmission aperture, and at least one sound port formed in the housing. The system includes an optical code symbol reading subsystem for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. An electro-acoustic transducer is disposed in the housing for producing sonic energy. Also, an acoustic-waveguide structure is disposed in the housing, for coupling the sonic energy produced from the electro-acoustic transducer, to the at least sound wave port formed the housing, to audibly signal the reading of a code symbol to the operator of the optical code symbol reading system.
