Abstract: A complex device that integrates a beam shaping aperture in a printed circuit board of the complex device (e.g., scanner or barcode reader or optical module) is provided. The complex device has a light-emitting diode pattern projection system. The pattern projection system includes one or more light-emitting diodes and a printed circuit board. The printed circuit board has one or more apertures and one or more receptacles. The one or more receptacles are positioned behind the aperture and receive the one or more light-emitting diodes. The printed circuit board with receptacle offer self-alignment for the light emitting diodes. The beam shaping aperture in front of the light-emitting diodes allows light to pass through the aperture that is part of the printed circuit board layer of the complex device.

Abstract: The present invention relates to an active alignment method of a receiving device (2, 2?) including a sensor (4) and of a illumination device (6, 6?) including at least one light source (18, 8?) suitable for emitting a beam of light, including: —Assembling said receiving device (2, 2?); —Stably fixing said receiving device (2, 2?) on a chassis (30); —Actively aligning an optical group (11, 11?) of said illumination device (6, 6?) with respect to said light source (18, 18?); —Fixedly connecting said optical group (11, 11?) of said illumination device to said light source (18, 18?); —Actively aligning said illumination device (6, 6?) with respect to said receiving device (2, 2?); and —Stably fixing said illumination device (6, 6?) to said chassis (30).

Abstract: Systems and methods of operation for a machine-readable symbol reader for estimating the distance of a scanned target object or item labeled with indicia, such as a machine-readable symbol. The reader may include an illumination subsystem which projects a light pattern (e.g., line) out from the reader. The reader may capture an image of the target object while the light pattern is projected thereon and analyze at least one detectable characteristic of the pattern to estimate distance of the target object relative to the reader. A one-dimensional sensor array of the reader may be exploited in part for imaging a symbol and in part for imaging detectable characteristics (e.g., edges) of the projected illumination pattern which allows for estimation of the reading distance. A central portion of the one-dimensional sensor array may be dedicated to imaging a machine-readable symbol and lateral portions may be dedicated to implementing a range finder.
