摘要： Indicia are imaged at a workstation having windows arranged in intersecting planes. The workstation also has solid-state imagers with fields of view that are split into intersecting subfields that look out through the windows, as well as illumination assemblies each having multiple light sources that illuminate each subfield with illumination light over an illumination field that overlaps a respective subfield. Light-modifying elements, such as lenses or baffles that are radially offset from the multiple light sources, condition the illumination light from the multiple light sources to be generally uniform in light intensity over at least one illuminated subfield.

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： An apparatus for and method of electro-optically reading targets arbitrarily oriented in a workstation, such as a dual window workstation, employs a solid-state imager for capturing return light from the targets over a field of view. The imager has an array of sensors arranged along mutually perpendicular array axes. An optical system splits the field of view into a plurality of subfields of view that extend through a workstation window to a target. One subfield is optically configured to enable the imager to capture light from the target along one array axis. Another subfield is optically configured to enable the imager to capture light from the target along the other array axis. A controller processes the captured light in both the one and the other subfields to enable the reading of the arbitrarily oriented target in the workstation independently of target orientation relative to the array axes.

摘要： A checkout system employs a bi-optical workstation having dual windows and a main reader for electro-optically reading indicia on products to be processed at the workstation through at least one of the windows. The workstation is supported by a countertop and has a raised housing extending upwardly away from the countertop. An auxiliary cordless reader is used for electro-optically reading the indicia in a handheld mode when the main reader is not operated. A cradle bounds a compartment in which the auxiliary cordless reader is removably received when not in the handheld mode. The cradle is supported by the raised housing above and remote from, and out of direct contact with, the countertop to form a zero-footprint therewith.

摘要： A solid-state imager is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing light along an optical axis over a field of view from diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. An optical converter is located within the housing, for optically modifying and asymmetrically magnifying the field of view along mutually orthogonal directions generally perpendicular to the optical axis, and for increasing resolution of the imager along one of these directions.

摘要： A hand-held bar code reader including a housing bounding an interior, a window, a generally planar printed circuit board mounted in the interior, and an optical scanning assembly mounted on the board and including a scanner for directing a light beam through the window at an acute angle relative to the board. A scanning element of the reader is manufactured by spacing a first and second support element apart by a gap bounded by edges of the support elements; injection molding a curable, elastomeric material in flowable form over the edges and into the gap; and allowing the curable, elastomeric material to cure and bond to the edges, and form a flexible hinge in the gap for enabling movement of the support elements relative to one another both away from and toward a stable rest initial position.
