摘要： Laser light reflected from a bar code symbol pattern is detected by a photodetector mounted in a portable scanning head of a laser scanning system. By selecting appropriate threshold values on the analog signal generated by the photodetector, the analog signal is converted to a series of pulses, each pulse width accurately corresponding to the width of a bar from the scanned pattern. A plurality of functions can be determined from the series of pulses, each function being independently selected by keyboard entry from the head, displayed on the head, and/or recorded by a printer remote from the head. Single line or multiple line scans in two orthogonal directions relative to the pattern may be selected. A bimorph or speaker-type oscillatory element may be utilized as a miniature scanning element. Circuitry for synchronizing scanning along both axes, and for generating a signal to drive the bimorph in a uniform, constant velocity manner is also disclosed.

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 bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products over a full coverage scan zone by splitting each field of view of only two imagers into three subfields that pass through each window and fill the scan zone and minimize dead areas therein. Twisting of the subfields relative to the windows is minimized so that the subfields fit fully with minimal clipping through each window. Splitting of each field of view is remotely performed well away from each imager. The imagers have lens assemblies of substantially the same optical power and are spaced from their respective windows by substantially the same distance.

摘要： A reader for and method of electro-optically reading symbols aim a front of a handheld housing at a symbol during reading. A solid-state, low resolution image sensor having a linear array of pixels is arranged in the housing and has less than 2000 pixels in number. The pixels sense return light returning along an optical path away from the symbol that is located in an extended range of working distances relative to the front of the housing. An imaging lens is positioned deep in the housing at an increased spacing of at least one inch as measured along the optical path away from the front of the housing, for capturing the return light over a reduced scan angle that is less than 40 degrees, and for projecting the captured light onto the sensor. A controller processes the return light sensed by the imager into data relating to the symbol.

摘要： 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.

摘要： Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of an over-power condition not conforming to preestablished regulatory standards. In one embodiment, during an operational mode, a difference between laser drive currents at two operating points is compared to a difference between laser drive currents at the same two operating points during a calibration mode. The over-power condition is recognized when the difference during the operational mode exceeds the difference during the calibration mode by a predetermined amount. In another embodiment, the laser is only energized to emit the beam at a reduced power level well below regulatory standards for staring at even if a motor drive failed.
