Bioptical laser scanning system for providing six-sided omnidirectional bar code symbol scanning coverage at a point of sale station
First Claim
1. :
- A method of providing six-sided 360-degree omnidirectional bar code symbol scanning coverage from a bioptical laser scanning system located at a point of sale (POS) station, said method comprising the steps of;
supporting at a POS station, a bioptical laser scanning system including a horizontal section integrally connected to a vertical section, a horizontal-scanning window formed in said horizontal section, a vertical-scanning window formed in said vertical section, and being substantially orthogonal to said bottom-scanning window, a first laser scanning plane generation mechanism disposed within said horizontal section, and a second laser scanning plane generation mechanism disposed within said vertical section; and
generating a first plurality of laser scanning planes from said first laser scanning plane generation mechanism, and projecting said first plurality of laser scanning planes through said horizontal-scanning window, and also generating a second plurality of laser scanning planes from said second laser scanning plane generation mechanism, and projecting said second plurality of laser scanning planes through said vertical-scanning window, so that (i) said first and second pluralities of laser scanning planes (i) intersect within predetermined scan regions contained within a 3-D scanning volume defined between said horizontal-scanning and vertical-scanning windows, and (ii) generate a plurality of groups of quasi-orthogonal intersecting laser scanning planes within said 3-D scanning volume, and (ii) said plurality of groups of intersecting laser scanning planes form a complex omni-directional 3-D laser scanning pattern within said 3-D scanning volume capable of scanning a bar code symbol located on the surface of any object, including a six-sided rectangular box-shaped object, presented within said 3-D scanning volume at any orientation and from any direction at said POS station so as to provide six-sided 360-degree omni-directional bar code symbol scanning coverage at said POS station; and
where at least one of said plurality of groups of quasi-orthogonal intersecting laser scanning planes are projected onto each of the six sides of a six-sided rectangular box-shaped object as said six-sided rectangular box-shaped object is passed through said 3-D scanning volume while one side of said box-shaped object is facing said horizontal-scanning window and another side of said six-sided rectangular box-shaped object is facing said vertical-scanning window.

Abstract
A bioptical laser scanning system at a point of sale (POS) station, that generates and projects a first plurality of laser scanning planes through a horizontal-scanning window, and a second plurality of laser scanning planes through a vertical-scanning window. The first and second pluralities of laser scanning planes intersect within predetermined scan regions contained within a 3-D scanning volume defined between the horizontal-scanning and vertical-scanning windows, and generate a plurality of groups of intersecting laser scanning planes within the 3-D scanning volume. The plurality of groups of intersecting laser scanning planes form a complex omni-directional 3-D laser scanning pattern within the 3-D scanning volume capable of scanning a bar code symbol located on the surface of any object, including a six-sided rectangular box-shaped object, presented within the 3-D scanning volume at any orientation and from any direction at the POS station so as to provide six-sided 360-degree omni-directional bar code symbol scanning coverage at said POS station.
