  • Patent number: 10256913
    Abstract: An optical driving device and an optical communication system are provided which can improve signal quality of laser light that uses a PAM method. A laser driver drives a semiconductor laser by using an N-level (N is an integer of 3 or more) PAM signal. A clock control circuit determines a driving timing of the laser driver. In a case where N=4, for example, the clock control circuit determines a driving timing in association with a transition of the PAM signal from a fourth level to a first level to be earlier than a driving timing in association with a transition in an opposite direction by a first time, assuming that levels are the first level, . . . , and the fourth level in an order from a level at which light intensity is minimum.

  • Patent number: 10152622
    Abstract: A system and method for providing visual feedback to facilitate multi-code (e.g., barcode) reading (i.e., scanning) is presented. The visual feedback will project a read status for each code scanned. The visual feedback for a particular code will be projected onto that code. For example, an “X” projected onto a code would indicated that this code was not read and needed to be scanned again. This visual feedback minimizes the number of codes that need to be rescanned in the case of a read error.

  • Patent number: 10007823
    Abstract: Embodiments of the present disclosure provide code readers for reading codes provided as patterns imprinted on objects. Light interacts with a pattern by e.g. being reflected from or transmitted through the pattern, and at least some of the light that has interacted with the pattern is incident on photosensitive element(s) of one or more photodetectors of a code reader. The code reader employs centroid-measuring photodetector(s), i.e. photodetectors that detect light in such a manner that centroid of a pattern can be obtained directly from the photocurrents generated as a result of the photosensitive elements detecting light incident thereon. The code reader is then configured to process the detected light to determine a centroid of the pattern from the detected light and to decode data encoded in the pattern based on a position of the centroid. Such code readers are substantially less complex than camera-based devices and avoid mechanical scanning.

  • Patent number: 8939372
    Abstract: A mobile terminal and a decoding method thereof are disclosed. The decoding method comprises: capturing an image of a target barcode; invoking built-in decoding software to decode the target barcode; determining whether the decoding is successful, wherein if the decoding is successful, then barcode information of the target barcode is displayed and the process ends; and otherwise, if the decoding is unsuccessful, then the target barcode is sent to a decoding server; receiving barcode information obtained by the decoding server through decoding the target barcode; and displaying the barcode information of the target barcode. In this way, the present disclosure can decode various types of barcodes quickly and effectively so that the user can be informed of the barcode information of the various types of barcodes quickly and accurately.

  • Publication number: 20150021400
    Abstract: A barcode reader comprises a first lens assembly with a first field of view and a first optical path for first illumination from the first field of view to project to a first image sensor section. The barcode reader further comprises a second lens assembly with a second field of view and a second optical path for second illumination from the second field of view to project to a second image sensor section. The barcode reader further comprises a first illumination system positioned outside of the first field of view projecting the first illumination into the first field of view at a first angle from the first optical path. The barcode reader further comprises a second illumination system positioned between the second lens assembly and a point from which the first illumination system projects the first illumination into the first field of view.

  • Patent number: 8910872
    Abstract: An imaging reader for, and a method of, imaging targets, include a solid-state imager supported by a housing for capturing return light from a target over a field of view. An illumination light assembly performs both illumination and aiming functions. Illumination light is projected along an optical path through a passage in the housing to illuminate the target. The housing has boundary walls spaced along the optical path away from the imager and the illumination light assembly for clipping the illumination light projected through the passage to form on the target an aiming light distribution that visually indicates a periphery of the field of view to assist in positioning the target entirely within the field of view.

  • Publication number: 20140361085
    Abstract: An electro-optical code reading terminal for dynamically switching mode of operation from a printed code reading mode to an electronically displayed code reading mode is provided. The electro-optical code reading terminal measures and monitors, using one or more magnetic sensors, a magnetic field experienced at the electro-optical code reading terminal. When the electro-optical code reading terminal device determines that a change in the measured magnetic field exceeds a predetermined threshold within a predetermined time period, the electro-optical code reading terminal device infers presence of an electronically displayed code. The electro-optical code reading terminal device then switches its mode of operation from the printed code reading mode of operation to the electronically displayed code reading mode of operation.

  • Patent number: 8899484
    Abstract: 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.

  • Patent number: 8857719
    Abstract: A method of decoding a barcode includes generating a first illumination towards a target object with a first illumination level, capturing a first image during a first exposure time period, and determining a first location and a second location on a scan line in the first image to find a switchover condition. If the switchover condition indicates the presence of a mobile display device, the method further includes generating a second illumination towards the target object with a second illumination level, capturing a second image during a second exposure time period, and decoding the barcode in the second image. Here, at least one of the second illumination level and the second exposure time period is determined based on values of pixels on the scan line between the first location and the second location.

  • Patent number: 8857720
    Abstract: One aspect of the present disclosure is related to a barcode reader that includes a bright field illumination system, a dark field illumination system, and an additional illumination system that is better able to illuminate an area of the reader's field of view between the far zone (where bright field illumination is optimal) and the close zone (where dark field illumination is optimal). In this “center zone,” the dark field illumination may not be bright enough and the bright field illumination may not be diffuse enough for reading a barcode.
