    Abstract: An automatic omni-directional bar code symbol reading system for use in a POS environment. The system comprises a system housing having a horizontal housing section with a first light transmission window, and a vertical housing section with a second light transmission window. A plurality of linear-type bar code symbol reading stations are disposed in the horizontal housing section, for generating and projecting a complex of linear illumination planes through the first light transmission window and into a 3D volume definable relative to the system housing. At least one area-type bar code reading station is disposed in the vertical housing section, for generating and projecting an area illumination beam through the imaging window, and into the 3D volume. The complex of linear illumination planes and the area illumination beam enable the omni-directional reading of bar code symbols on an object passing through the 3D volume, and generation of symbol character data representative of the read bar code symbol. An object detection subsystem automatically detects the object passing through the 3D volume, and generates motion data representative of the detected object motion within the 3D volume. A control subsystem controls operations within the linear-type and area-type bar code symbol reading stations using control data derived from the motion data generated by the object motion detection subsystem.

    Abstract: A method of generating a complex laser scanning pattern from a bioptical laser scanning system for providing 360° of omnidirectional bar code symbol scanning coverage at a point of sale station that employs a plurality of laser scanning stations about two independently controlled rotating polygonal mirrors. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generates a 3-D omnidirectional laser scanning pattern between the bottom and side-scanning windows during system operation. The laser scanning pattern of the present invention comprises a complex of laser scanning planes, including a plurality of substantially-vertical laser scanning planes for reading bar code symbols having bar code elements (i.e. ladder type bar code symbols) that are oriented substantially horizontal with respect to the bottom-scanning window, and a plurality of substantially-horizontal laser scanning planes for reading bar code symbols having bar code elements (i.e. picket-fence type bar code symbols) that are oriented substantially vertical with respect to the bottom-scanning window.
