|---|---|---|---|
| 7216810 | Hand-supportable multi-mode digital imaging-based bar code symbol reader employing an automatic illumination and exposure control subsystem that automatically controls the operation of a multi-mode led-based illumination subsystem so that detected objects are sufficiently illuminated and good quality digital images thereof are formed and detected | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2007-05-15 |
| 7213762 | Hand-supportable imaging-based bar code symbol reader employing a CMOS-type image sensing array in combination with a band-pass optical filter subsystem, narrow-band illumination subsystem, and automatic light exposure measurement and illumination control subsystem | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2007-05-08 |
| 7188770 | Hand-supportable semi-automatic imaging-based bar code reading system wherein an led-based illumination subsystem automatically illuminates a detected target object in a narrow-area field of illumination, and illuminates the detected target object in a wide-area field of illumination upon manual activation of a trigger switch | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2007-03-13 |
| 7185817 | Hand-supportable digital imaging-based bar codes symbol reader employing multi-mode subsystems | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2007-03-06 |
| 7178733 | Hand-supportable imaging-based bar code symbol reader employing automatic object presence and range detection to control the generation of near-field and far-field wide-area illumination during bar code symbol imaging operations | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2007-02-20 |
| 7128266 | Hand-supportable digital imaging-based bar code symbol reader supporting narrow-area and wide-area modes of illumination and image capture | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2006-10-31 |
| 7086595 | METHOD OF AND APPARATUS FOR PROCESSING CAPTURED DIGITAL IMAGES OF OBJECTS WITHIN A SEMI-AUTOMATIC HAND-SUPPORTABLE IMAGING-BASED BAR CODE SYMBOL READER SO AS TO READ 1D AND/OR 2D BAR CODE SYMBOLS GRAPHICALLY REPRESENTED THEREIN | Xiaoxun Zhu, Yong Liu, Ka Man Au, Rui Hou, Hongpeng Yu +12 more | 2006-08-08 |
