Abstract: An optical scanner which is configurable to produce a single pattern or a plurality of patterns. The scanner includes an optics engine with first and second laser mounts, first and second detector mounts, a first laser in the first laser mount for producing a first scanning light beam, a mirrored spinner for directing the first scanning light beam, and a first detector in the first detector mount for converting first light reflected from an item with a barcode label into first electrical signals. The scanner further includes pattern mirrors for receiving the first scanning light beam from the mirrored spinner, for producing a first scan pattern from the first scanning light beam for scanning the item, and for directing the first light reflected from the item to the mirrored spinner, and control circuitry for controlling operation of the first laser and the mirrored spinner.

Abstract: Systems and techniques for scanner scale implementation and operation using a plurality of load cells mounted in a planar arrangement. A plurality of load cells is mounted to a scanner base. The load cells are secured within a mounting chassis in such a way that the load bearing elements of the load cells extend through the protective cover. The mounting chassis and load cells may be mounted to the scanner base. A scanner top plate may be secured to the load cells such that the weight of the scanner top plate and any object placed on the scanner top plate is borne by the load bearing elements of the load cells, part of the weight being borne by the load bearing element of each load cell. Upon presentation of an object for weighing, weight signals generated by the load cells are processed to produce a weight reading for the object.

Abstract: An optical scanner having enhanced item side coverage which scans all six sides of an item and an intermediate side. The optical scanner includes a scanner housing, a first optics assembly within the scanner housing including a horizontal aperture, and a second optics assembly including a second housing within the scanner housing including a substantially vertical aperture. The first and second optics assemblies are capable of scanning six sides of an item. At least one of the first and second optics assemblies additionally generates third scan lines for scanning an intermediate side of the item.

Abstract: A bar code scanner and method of operation thereof is disclosed. The bar code scanner comprises a housing including a surface having a transparent scanning window; and optical components including a spinner located within the housing. The optical components are arranged to produce both a first set of scan lines focused outside of the housing and remote from the scanning window; and a second set of scan lines focused outside of the housing and adjacent the scanning window. The method includes the steps of placing a bar code to be read in either a first position where said first set of scan lines are focused or in a second position wherein said second set of scan lines are focused.

Abstract: A barcode scanner window includes a transparent window pane having an electrically connecting loop laminated to the back side thereof. The loop extends around the perimeter of the pane and includes opposite ends to which electrical leads are joined.

Abstract: A spinner for a barcode scanner includes a plurality of mirror facets arranged oppositely in pairs in a polygon, with adjoining facets having different angles of inclination and different lengths for reflecting a laser beam in correspondingly different, variable sweep arcs. The spinner cooperates with a plurality of pattern mirrors in a barcode scanner embodiment for effecting a scan line pattern with extended coverage.

Abstract: A dual aperture optical scanner which employs a single laser beam to produce horizontal and vertical scan patterns. The optical scanner includes a housing having first and second apertures, a laser beam source, a mirrored spinner having a plurality of facets with different elevation angles for reflecting the laser beam in a plurality of directions, and a plurality of pattern mirrors within the housing for reflecting the laser beam from the spinner through the first and second apertures to an article having a bar code label to be scanned. The optical scanner also includes an optical transceiver for passing the laser beam and for collecting reflected light from the scanned article and a photodetector for generating signals representing the intensity of the light reflected from the article.

Abstract: A compact dual aperture scanner is disclosed. The scanner includes a horizontal cabinet including a horizontal aperture and a vertical cabinet including a vertical aperture. The vertical cabinet contains a laser source and deflecting mirror in a lower portion of the vertical cabinet and a polygonal spinner in an upper portion of the vertical cabinet. The laser source directs a laser beam at the deflecting mirror, which deflects the laser beam to the spinner. The spinner rotates, deflecting the laser beam into a plurality of rays. The rays strike a series of primary and secondary mirrors within the vertical and horizontal cabinets, which deflect the rays to produce a scan pattern at each of the horizontal and vertical apertures. When scattered light, such as may be reflected from a bar code, enters the vertical or horizontal aperture, the light is deflected by the secondary and primary mirrors to the spinner, where it is deflected to a collection lens and directed to the deflecting mirror.
