Abstract: A trigger-operated or triggerless scanner reads symbols with a first scan pattern in a first intended position of hand-held use. Either scanner may be mounted on a stand-alone fixture wherein the first scan pattern is converted to a second, different scan pattern, again for reading indicia in a second intended position of workstation use. Various signal processing digitizing circuits for faithful digital reconstruction of the symbols are disclosed.

Abstract: An optical scanner (30) has a scanner component mounted to a leaf spring (34) for oscillatory motion about an axis. An electromagnetic coil (58) and permanent magnet (56) cause a force to be applied to the scanner component away from a central, neutral position. Bending of the leaf spring provides a restoring force biasing the scanner component back towards the neutral position.

Abstract: The disclosure relates to systems and techniques for reading optical codes, and more particularly to code reading systems with plural imaging or scanning modules pointed in various directions toward a target volume, which increase the likelihood that a code symbol on an arbitrarily oriented object in the target volume will be read. Other aspects of the invention relate to use and configuration of hand held readers, docking devices, operator side rails, arched tunnels and mirrors for increasing the coverage of the system. Additional aspects of the invention relate to components associated with point of sale installations or code reading terminals including integrated scales, input pads, system controls and displays.

Abstract: A plurality of the areas of different light reflectivity of a bar code symbol, or the like, are simultaneously illuminated, using, e.g., a beam of laser light that has an elongated cross-section. The laser light beam is swept over the symbol in a direction transverse to the elongated dimension of the illuminated region so that a two-dimensional area of the symbol is illuminated over time, until the symbol is read. The light that reflects from the illuminated region of the symbol is imaged on a linear sensor array, which is then scanned or read out to produce signals representative of spatial intensity variations of the imaged light along a linear path in the field of view.

Abstract: An optical scanner such as a bar code scanner includes a segmented mirror (14), the individual sections of which have different profiles (16,18,20). By directing the scanning laser beam across the mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.
