    摘要： An illumination time of an illumination system and/or an exposure setting of an imaging system are adjusted by a proximity system operative for detecting a product entering a field of view in a bi-optical, dual window, point-of-transaction workstation. The proximity system includes an infrared emitter for emitting infrared light to the product, and an infrared sensor for sensing return infrared light from the product. Multiple predefined thresholds are stored for the sensed return infrared light, and a predefined illumination time and/or exposure setting are stored and assigned to each predefined threshold. Adjustment of the illumination time and/or of the exposure setting is performed by comparing the sensed return infrared light from the product in real time operation with the stored predefined thresholds.

    摘要： 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.

    摘要： A lensholder holds at least one fixed optical lens and a variable focusing element in a spaced relation along an optical path through which light passes in an electro-optical reader. The variable focusing element has a pair of electrodes across which a voltage is applied to optically modify the light passing through the fixed optical lens and the variable focusing element. The lensholder directly electrically conductively contacts the electrodes and establishes an electrically conductive path between each electrode and an exterior of the lensholder.

    摘要： A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color. The pixels are rendered symmetrical in cross-section by aligning a narrow dimension of a beam spot of a laser beam along scan lines of the raster pattern.
