Abstract: A system and method for processing a machine-readable code associated with an object moving relative to an imaging device may include imaging the machine readable code. A determination may be made as to whether image data of the machine-readable code is clipped along a leading edge of a first image frame. If the machine-readable code is determined to be clipped, (i) image data of the machine-readable code in the first image frame may be skipped, and (ii) image data contained in a subsequent image frame may be processed. Otherwise, if the code is not determined to be clipped, processing image data in the subsequent image frame may be skipped.

Abstract: A system and method for reading a machine readable code associated with an object moving relative to an imaging device may include capturing a first image of the machine readable code at a first resolution. A second image of the machine-readable code with a non-integer pixel shift in alignment at the first resolution may be captured. An interleaved image may be formed from the first and second images. An image of the machine-readable code may be generated at a second resolution using the interleaved image, where the second resolution is higher than the first resolution.

Abstract: Disclosed is a linear barcode scanning system and associated methods for reading a linear barcode borne by an item during transport of the item along a direction of transport by a transport system. A displacement between consecutive scanline samples is determined based on movement imparted to the item from an item-transport system. Image data representing an area of the linear barcode located between positions of the linear barcode corresponding to the consecutive scanline samples is synthesized by quantizing a portion of a first one of the consecutive scanline samples and extending the quantized portion along a direction of the displacement to provide for a depiction of the area of the linear barcode.

Abstract: A scanning system has a collimated light source and a movable reflective surface. The surface receives light from the light source, reflects the received light to a target surface, receives light reflected from the target surface, and reflects this light to a detector. An aperture disposed between the reflective surface and the target surface has a non-transmissive portion with a width in a direction perpendicular to the laser scan direction that varies over the scan direction.

Abstract: A conveyor system including a rack having a first level with an input conveyor being moveable with respect to the rack in a first direction of travel, a first storage conveyor being moveable with respect to the rack in a second direction of travel, a second storage conveyor being moveable with respect to the rack in a third direction of travel, and a cross transfer assembly being movable with respect to the input conveyor in both the second direction of travel and the third direction of travel so that the cross transfer assembly moves the object from the input conveyor onto one of the first storage conveyor and the second storage conveyor. The second direction of travel and the third direction of travel are transverse to the first direction of travel.

Abstract: A conveyor system for processing items on which radio frequency identification tags are disposed has a conveyor that conveys items through a path of travel, and an antenna disposed proximate the path of travel. Circuitry in communication with the antenna may associate RFID tag data with a package on the conveyor based on a difference signal from elements in the antenna.

Abstract: A system and method for auto-calibrating a barcode scanning tunnel to determine the orientation of one or more cameras with respect to a range finder and a conveyor belt comprises providing a scanning tunnel having a moveable surface, at least one range finder having an orientation, at least one camera having an orientation and at least one calibration object having at least one indicia disposed in a predetermined relationship to one or more features of the at least one calibration object, capturing at least one image of the at least one calibration object by the at least one camera, electronically detecting the at least one calibration object at least one indicia and the one or more object features and electronically calculating at least one component of the at least one camera orientation with respect to the moveable surface in response to information obtained from the image and the at least one calibration object at least one indicia.

Abstract: A system for scanning objects having at least two linear array sensors, adapted to detect light input signals, is provided. A lens is optically connected to each of the linear array sensors, and are adapted to receive and transmit an optical image located in a respective lens field of view along a respective lens axis to the respective one of the at least two linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis across a depth of the field of view is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe. This arrangement provides a wider system field of view with generally more uniform resolution.

Abstract: An apparatus and method for calibrating a barcode scanning tunnel has a conveyor structure and a scanning system. The scanning system has a laser light source, an optics system, and a processor. In a calibration mode, the processor locates a central area of the conveyor structure and identifies a first location at which there is a height above the level of the central area according to a predetermined criteria. The processor identifies a second location that is offset, by a predetermined distance in a direction transverse to the direction of travel of the conveyor structure, from the first location.
