Abstract: Scanned barcodes represented by an electrical signal are preprocessed in a PLA and delivered to a microprocessor in a form that permits efficient final processing of the data. High speed edge detection produce edge markers for the control logic and counting circuits coupled with a Johnson state counter to logically sequence the processor. Logarithmic conversion compresses the counted time interval to a single data word that can most efficiently be processed by the host microprocessor. Logic between the preprocessor and the microprocessor transfer digital representations of each bar and space to preassigned respective areas in the microprocessor memory. Bar/space margin detection performs a ratiometric comparison of each bar and space to determine every occurrence of 10:1 ratios of both bar/space and space/bar. Pointer signal information is transferred to the microprocessor indicating precisely where in memory each 10:1 margin ratio is located. A digital filter excludes spurious bar/space width in the preprocessor.

Abstract: An apparatus (10) is disclosed comprising a base capable of receiving a camera including a lens, and a projector coupled to the base and adapted to project a plurality of beams of light 12, 14) onto a plane positioned at a focus distance from the base, wherein the projections of the beams of light on the plane are geometric shapes (16, 18), and wherein an intersection of the geometric shapes is at the center of the field of view of the lens when the lens is installed on the base. In addition, an apparatus is disclosed comprising a base capable of receiving a camera including a lens, an image processor capable of being coupled to the camera for processing an image of a target captured by the camera, and a confirmation projector coupled to the image processor, wherein the projector projects a confirmation beam onto the plane of the target when the image processor signals the confirmation projector that it has processed the image.

Abstract: The disclosure describes an apparatus and method for automatic gain control during scanning. The apparatus comprises an optical detector to receive an optical signal reflected from a symbol positioned within a scan window by an optical beam scanned from a leading edge of the scan window to a trailing edge of the scan window; and a processor coupled to the optical detector to adjust the gain of the optical detector during the beam scan. The process comprises receiving an optical signal using an optical detector, wherein the optical signal comprises optical energy reflected from a symbol positioned in a scan window as an optical beam scans from a leading edge of the scan window to a trailing edge of the scan window, and adjusting the gain of the optical detector during receipt of the optical signal. A calibration process is disclosed comprising calibrating the optical detector to obtain a plurality of gain corrections, each gain correction corresponding to a different position between a leading edge and a trailing edge of a scan window, and storing the plurality of gain correction.
