Abstract: A flexible scan element for a laser scanner is disclosed. The flexible can element may be made from a non-linear elastomeric material that twists sufficiently for scan operation but resists unwanted motion from shock/vibration through the use of a rigid motion-limiting member encapsulated, at least partially, within the body of the flexible scan element. In this way, no external components are required for limiting excess motion.

Abstract: A method for operating an indicia reader such as a laser scanner is provided. The method affords a simplified technique for monitoring the offset between the drive frequency and the resonant oscillation frequency of the laser scanner. The phase offset between the drive frequency and the sense frequency is monitored to derive the drive frequency's offset from the resonant oscillation frequency.

Abstract: A hand-held indicia-reading device includes a housing and a cable having a unitary-construction. The indicia-reader has a head portion with an indicia-reading system including a printed circuit board. The entire handle portion of the reader is typically over-molded onto a host-connector cable. The host-connector cable includes a circuit board connector on one end and a connector for connecting to a host at an opposite end extending from a base portion of the handle.

Abstract: A method for manufacturing laser scanners is provided. Laser scanners are configured to drive their light-deflecting assemblies at a fixed drive frequency. By selecting for inclusion in the laser scanners only those light-deflecting assemblies that have resonant oscillation frequencies falling within a specified range, operation of the laser scanners remains within engineering tolerances even through extreme environmental changes. Moreover, the method results in laser scanner having greater unit-to-unit consistency during operation even in extreme environments.

Abstract: A system for selectively reading code symbols includes a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem's field of view. The system also includes a code-symbol-decoding processor that detects a marked region of interest within the code-symbol-capturing subsystem's field of view. After initialization, the code-symbol-decoding processor decodes only those code symbols falling within the marked region of interest.

Abstract: The system includes a housing having a light transmission window and produces an extremely-elongated laser beam having an elongation ratio (ER) that is defined as greater than 4.5 for any point within the working range of the laser scanning bar code symbol reading system. A laser scanning mechanism is provided for scanning the extremely-elongated laser beam out the light transmission window and across a scanning field defined external to the housing, in which a bar code symbol is present for scanning by the extremely-elongated laser scanning beam.

Abstract: A laser scanning bar code symbol reading system for scanning and reading poor quality or damaged bar code symbols. The system includes a housing having a light transmission window; an extremely-elongated laser beam production module for producing an extremely-elongated laser beam having (i) a direction of propagation extending along a z reference direction, (ii) a height dimension being indicated by the y reference direction, and (iii) a width dimension being indicated by the x reference direction, where x, y and z directions are orthogonal to each other. Each extremely-elongated laser beam is characterized by an elongation ratio (ER) that is defined as Y/X>4.
