Abstract: An improved prismatic polygonal reflector with increased aerodynamic properties and reduced scattering of reflected light is provided. The reflector may be used for scanning, and may include a first end, a second end, a plurality of side surfaces located circumferentially about a center axis of the reflector, and a plurality of intersections joining the plurality of side surfaces. Each of the plurality of intersections includes a curved or a flat portion and a pointed portion aligned circumferentially with other pointed portions on the plurality of intersections to provide a circumference around the reflector for light to reflect and form a scanning beam without light scattering. A system and method for scanning with the reflector is also provided.

Abstract: A system for scanning objects having at least two linear array sensors, adapted to detect light input signals, is provided. A lens is optically connected to each of the linear array sensors, and are adapted to receive and transmit an optical image located in a respective lens field of view along a respective lens axis to the respective one of the at least two linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis across a depth of the field of view is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe. This arrangement provides a wider system field of view with generally more uniform resolution.

Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored. A second scanned code data is searched for a second string matching at least part of the first string in the cluster. If a match is found, then the second string is added to the end of the cluster. The cluster is closed upon detection of a stop pattern and is then decoded.

Abstract: A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code by relatively shifting the code fragments until they are in registration.

The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code. The registration device relatively shifts the code fragments until they are in registration. Thus one of the fragments provides a beginning portion of the code and the other an ending portion. Both fragments provide a registered middle portion of the code.
