The imaging module includes a solid-state imager having an array of image sensors for capturing return light from the indicia during reading. A laser scanning module is also supported by the housing and includes a scanner for scanning at least one of a laser beam from a laser and a field of view of a light detector in a scan pattern across the indicia during reading. A controller is operatively connected to the modules, and is operative for preventing reading interference between the modules during reading. | 01-01-2009 |
| 20090078775 | Electro-optical imaging reader having plural solid-state imagers with shutters to prevent concurrent exposure - A bioptical workstation includes plural image capture modules for capturing images of indicia along different fields of view. Each module includes an illuminator for illuminating the indicia with illumination light, a megapixel imager with a rolling shutter for sequentially capturing the return light, and a shutter element for passing the return light to its imager in an open state, and for blocking the return light from other modules from reaching its imager in an closed state. A controller prevents interference among the modules by controlling the shutter element to assume the open state only during a respective exposure time period during which its imager produces an electrical signal indicative of the indicia, and by controlling the shutter element to assume the closed state at all times other than the respective exposure time period to prevent capture of the return light from the other modules. | 03-26-2009 |

The ASIC is operative for storing the pixel data received by the ASIC that lies on each virtual scan line as stored pixel data. The controller is operative for decoding the stored pixel data on each virtual scan line. | 04-22-2010 |

| 20110089244 | ELECTRO-OPTICAL READER WITH VISIBLE INDICATION OF SUCCESSFUL DECODE IN LINE OF SIGHT OF OPERATOR - A coded symbol is electro-optically read by a moving beam reader or an imaging reader that employs a light source for emitting light to the symbol and a detector for detecting return light from the symbol. The light source can be a laser used in a moving beam reader, or an illuminator or an aiming source used in an imaging reader. A controller decodes the symbol by processing the return light, and controls the light emitted from the same light source to generate a visible indication signifying a successful decoding of the symbol on a surface bearing the symbol within a line of sight of an operator. | 04-21-2011 |

The docking station includes a universal serial bus (USB) socket interface supported by the docking station, and a USB extension cable connected to the USB socket interface. The USB cable extends away from the docking station and terminates in a USB plug interface. A radio frequency (RF) peripheral is inserted into the USB socket interface, for wireless RF communication with the reader when the reader is not supported on the docking station. The USB cable is connected to power contacts on the docking station for mating with charging contacts connected to a rechargeable battery in the reader to charge the battery when the reader is supported by the docking station. | 05-05-2011 |
