Abstract: A scale and scanner system includes a controller to control operation of the scale and scanner system. A scale calibration parameter memory for storing scale calibration parameters is coupleable to the controller. A scanning module and a scale module are coupleable to the controller. When the controller is not coupled to the scanning module or scale module, the scale calibration parameter memory remains in the system.

Abstract: An imaging optical code scanner is presented that includes improved vertical optics for capturing images of items being presented for scanning. The improvements include multiple image capture devices, multiple illumination modules and viewing of items being scanning from four different directions. This allows for high pass-by scanning of items.

Abstract: An apparatus and methods are presented for improving image scanning. A point of sale terminal apparatus, including an imaging scanner, provides information to an operator indicating the optimal scanning position for an optical code for efficient first pass scanning by the imaging scanner. The information includes real-time video from an image capture device of the imaging scanner displayed on an operator's display device.

Abstract: A low profile tri-aperture optical code scanner and operating method are presented. The scanner includes three scanning apertures and a front and a rear low profile housing component. Each housing component includes a scanning aperture tilted toward a point about the center of the scanner. A third scanning aperture is located in a horizontal top surface of the scanner. The low profile housing elements allow an operator to scan items by standing either on the front side or the rear side of the scanner. When used in a convertible point of sale terminal, a cashier operates the scanner from the front side of the scanner when the terminal is in the assisted mode and a customer operates the scanner from the rear side of the scanner when the terminal is in the self-service mode.

Abstract: Improved systems and techniques for imaging bar code processing. One or more cameras are deployed in a bar code scanner, oriented so that an imaging device of each camera is oriented such that rows of data elements in the imaging device are oriented nonorthogonally with respect to a preferred orientation of a bar code. One or more imaging devices captures bar code data representing light and dark spaces of the bar code. The captured bar code data is analyzed to create one or more rows of data completely transecting the bar code, and the rows of data are processed to generate a scan signal which is in turn processed to extract bar code data.

Abstract: Systems and techniques for multiple laser and multiple detector bar code scanning. multiple laser sources generate multiple laser beams directed to a rotating spinner and along optical paths to emerge from a scanner as multiple scan beams. The scan beams trace out a scan pattern within a scan volume. As the multiple scan beams strike an object within the scan volume, reflected light rays are produced representing reflections of the multiple scan beams. As the reflected light rays enter the scanner, they are directed to a collector and focused onto a plurality of detectors so that reflected light rays representing reflections of each scan beam are focused onto a detector associated with the laser source from which the scan beam originates.

Abstract: Techniques for using imaging information computed from examining a scanner signal are described. When one or more objects passes within a field of view of a scanner, scan patterns emerging from one or more scanner windows and reflected from the objects back into the scanner windows produce one or more scanner signals. The scanner signals are processed to obtain beam position and beam length information to improve the accuracy of bar code decoding and to compute imaging information for objects within the field of view of the scanner. The imaging information for the objects is compared with bar code information for the objects. The expected number, size and shapes of objects indicated by the bar code information is compared with the actual number, size and shapes of objects in order to determine if valid scans occurred or if missed, double or otherwise erroneous scans occurred.
