  • Patent number: 8146824
    Abstract: A floating trigger assembly is mounted on a housing of an ergonomically triggered reader for electro-optically reading a target to initiate the reading when manually actuated by an operator. The trigger assembly includes a trigger support in the housing, and a floating trigger engageable by the operator exteriorly of the housing and mounted for initial translatory motion toward the trigger support upon initial actuation by the operator, and for turning motion about an axis after the floating trigger contacts the trigger support.

  • Patent number: 8146822
    Abstract: A multi-imaging scanner (12) and method for imaging indicia (14) located on target objects (16) is featured in the present disclosure. The multi-imaging scanner (12) includes one or more cameras (30) for imaging indicia (14) on target objects (16) and a sensor array (48) associated with each of the one or more cameras (30) for capturing a series of frames (FR1-FR6) within a respective field of view of each of the one or more cameras (30). The multi-imaging scanner (12) further includes a processor (44) coupled the one or more cameras (30) for imaging and decoding the indicia (14) on the target objects (16) captured in the frames by the one or more cameras. The frames (FR1-FR6) include a first frame having a first pre-set exposure time and a second frame having a second pre-set exposure time such that first and second pre-set exposure times are of different duration.

  • Patent number: 8030630
    Abstract: A method and apparatus comprising an imaging system (10) with safety control for imaging target objects having a scanning arrangement (14) including a sensor assembly (22) for capturing an image from a target object. The sensor assembly (22) has a field-of-view focused by an optical arrangement (24) onto a sensor array (28). The imaging system further comprises an illumination assembly (18) having a housing (30), illumination source (38), light pipe (42), and projection lens (36). The illumination assembly (18) provides light energy toward the sensor assembly field-of-view for illuminating the target object to be imaged on the sensor array (28). The light pipe (42) comprises a multi-walled tapered body (52) having an input face (40). The walls of the body (52) create mirrored images of the illumination source (38), together with the projection lens redistribute the amount of light energy directed at the eyes of a human.

  • Patent number: 8028919
    Abstract: The disclosed bar code reader includes an auto-focusing component for rapidly producing in focus images. An imaging system makes use of an aiming pattern that impinges upon the coded indicia of a target. The imaging system includes a light monitoring pixel array and a focusing lens that is fixed with respect to the pixel array for transmitting an image of the target object onto the pixel array. The imaging system also includes a moveable prism mounted for movement along a path of travel to transmit light passing through the focusing lens onto the pixel array. A drive motor moves the prism relative the lens to adjust a focus of an image of the object formed at the pixel array.

  • Patent number: 8028915
    Abstract: A current data capture system has a set of configuration parameters operative for enabling the current data capture system to capture transaction data. A configuration host is operative for pulling the set of configuration parameters from the current data capture system, and for pushing a pulled set of configuration parameters to at least one additional data capture system to enable the at least one additional data capture system to capture the transaction data.

  • Patent number: 8028917
    Abstract: An imaging reader includes an illuminating light assembly, an illuminating control operative to control either the intensity or the duration of the illumination light projected by the illuminating light assembly, and a solid-state imager. The solid-state imager includes a matrix of optical-sensors and a signal processing circuit coupled to the matrix of optical-sensors. The controller is operative to determine the optimized exposure level of the illuminating control and the optimized gain of the signal processing circuit based on a measured voltage of a voltage power source for the solid-state imager.

  • Patent number: 8025234
    Abstract: An arrangement for, and a method of, enhancing performance of an imaging reader for imaging symbols to be read, includes a solid-state imager supported by the reader and having an array of image sensors for capturing return light from a symbol as pixel data over a two-dimensional field of view, an application specific integrated circuit (ASIC) operatively connected to the imager for receiving the pixel data, and a controller operatively connected to the ASIC for mapping the ASIC with at least one virtual scan line, and preferably a plurality of virtual scan lines, each extending over the field of view in an omnidirectional scan pattern. 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.

  • Patent number: 8025519
    Abstract: A cable release accessory releases an electrical cable that is connected to an electrical device, such as a handheld moving beam reader or a handheld imaging reader for electro-optically reading symbols. The cable is terminated by a male connector that engages a female socket in the housing during reading. The male connector has a movable locking clip that releases the cable when moved. The accessory includes a holder mounted on the cable exteriorly of the device, and an elongated actuator supported by the holder and extending into the device into an overlying relationship with the locking clip. The actuator is movable against the locking clip for depressing the locking clip to release the cable.
