Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored. A second scanned code data is searched for a second string matching at least part of the first string in the cluster. If a match is found, then the second string is added to the end of the cluster. The cluster is closed upon detection of a stop pattern and is then decoded.

Abstract: The present invention provides an inexpensive scanner that can scan at near to medium focal lengths. A light beam is generated to illuminate a target area on the scanned object. A mirrored surface directs the light beam towards the object and light reflected from the object to a detector. The detector is positioned to receive a constant amount of reflected light from the mirrored surface.

Abstract: A presentation imaging system used for imaging machine readable information on an object is provided. The system includes an imaging device coupled to a processor. The imaging device senses the presence of an object within a field of view. A light source projects a structured beam at a first intensity to define an imaging area generally co-extensive with the field of view. Upon detection of the object, the processor signals the light source to project the beam at a second, higher intensity for imaging.

Abstract: An automatic focusing camera which includes an image sensor is provided having a fixed lens system with a lens having an object side and an image side. The fixed lens system is located in a fixed position relative to the image sensor. A mirror is moveably positioned between the image side of at least one lens and the image sensor. The mirror is located at an angle such that an image observed through the fixed lens system is reflected toward the image sensor. An actuator is connected to the mirror and moves the mirror relative to the lens system to change a distance between the lens system and the image sensor to adjust an object focal length between an object and the object side of the lens.

Abstract: The invention refers to a method and device for identification and authentication of an object by means of coded information applied to the object. The function of said method and device is based on the principle of a laser scanner comprising two photoelectric detectors provided with decoding devices. In a first measuring channel and in classical manner an open coding in the form of a barcode is registered based on the different reflection/absorption of light at dark and light spots. In a second measuring channel the coded safety information applied on the same object is detected. By preference, the latter information is applied in form of luminescent safety pigments/coloring substances. By means of the source of light of the barcode scanner said safety pigments/coloring substances are excited at a defined optical wave length and show a specific luminescence in another wave length band. By preference, the detector device of the second measuring channel is provided with a wave length selecting element.

Abstract: A scanning system utilizes a randomly addressable image sensor which is selectively positioned at the Scheimpflug angle in the image plane in order to detect focused light reflected from an object. Light reflected from the object is focused onto the sensor through an objective lens. Since the sensor is mounted at the Scheimpflug angle, each strip within the depth of field of the object plane has corresponding pixels on the sensor which are in focus.

The dimensioning system is comprised of a light source which generates a scan beam that is moved by a mirrored wheel. A line scan camera whose field of view tracks the moving scan beam receives images of the scan beam and outputs a signal which is processed to compute a three dimensional box structure of the scanned object.
