摘要： The invention is optical assembly for use in a barcode reader that includes a frame having a rear housing and a pair of arms outwardly extended from the housing. An optical card containing an imaging lens is slidably received in a rear guideway situated between the arms. An aperture card is slidably received in a front guideway situated between the arms in front of the lens. Lamp support brackets are also mounted to either side of the arms. Each bracket contains a pair of LEDs that are aligned in coplanar relation with the imaging lens. A cylindrical lens is mounted in front of the lamp support brackets within the arms of the frame to magnify and focus the illumination from the LED upon a target in barcode space. A horizontally extended field stop aperture is positioned in front of each LED.

摘要： The present invention relates to an optical reader that includes a color imaging assembly that generates color imaging data. An image analysis circuit determines if the acquired image should be characterized as a color photograph or as including a graphical symbol. A processing circuit processes the imaging data based on the image analysis circuit's determination of whether the image is a graphical symbol or a color photograph. The present invention allows a user to acquire and process both color images and graphical symbols, such as bar codes, text, OCR symbols or signatures. The optical reader of the present invention is also configured to associate an acquired image with at least one other acquired image.

摘要： The present invention is an imaging device equipped with decode funtionality configured to operate in at least one of four user selected modes. In a first, nullmessage onlynull mode, the device stores into a designated memory location a decoded-out message corresponding to a decodable indicia. In a second, nullimage onlynull mode, the device stores into a designated frame storage memory location an image representation of a scene. In a third, nullimage plus messagenull mode the device stores into a designated frame storage memory location an image representation comprising a representation of a decodable symbol and into the same or other memory location the decoded-out message decoded from the decodable indicia, or data corresponding to the same. In the fourth, nulltwo-step message and imagenull mode, the device is controlled to capture an image a first time for decoding a decodable indicia and a second time for capturing an image that is associated with the decoded-out message corresponding to the decodable indicia.

摘要： A data collection network featuring a plurality of cordless optical scanners communicating to a base terminal is disclosed. The cordless optical scanners are used for reading 2D optically encoded symbols. The optical scanner converts the 2D optically encoded symbol into decoded data. The optical scanner has a packet assembly component that converts the decoded data into packets. A communications component transmits the packets to the base terminal. The decoded data is packetized to accommodate 2D data codes such as PDF417, microPDF, Code One, DataMatrix, MaxiCode, or other 2D symbols. All of these symbols have maximum data capacities exceeding 1,000 bytes of information per symbol. Thus, the data collection network of the present invention provides users with the data transmission capacity required to use high-density data optical bar code symbols in an untethered working environment.

摘要： The invention relates to an optical reading system comprising an optical reader and a host processor. In one aspect of the invention, the host processor may be configured to transmit a component control instruction in response to a user input command input by a user of the host processor to remotely control the reader. The optical reader subsequently receives the transmitted component control instruction and executes the component control instruction substantially on receipt thereof. In one embodiment, execution of the component control instruction by the optical reader has the same effect as the reader trigger being manually pulled by a reader operator.

摘要： Briefly stated, the operating depth of field for a bar code scanner, preferably a laser scanner, is increased by placing a cubic phase mask (CPM) in the scanning beam. The masked beam is then scanned and reflected off a bar code and received by a photodetector. The received signal is then processed to recover the original unperturbed representation of the bar code pattern. The processed signal has an increased depth of field over an unmasked scanner signal.

摘要： In the present invention, the control unit of an optical reader analyzes image data being generated by the imaging element of the reader and changes the mode of operation of the reader if the image data indicates that machine readable indicia, such as a bar code symbol or a text character, is likely in the field of view of the reader. Normally, analysis of image data includes the step of detecting for edge transitions in the image information. If the control unit determines that the image data includes more than a predetermined number of edge transitions, then the control unit imparts appropriate control over various reader elements to change the mode of operation of the reader. Normally, the control unit changes the mode of operation of the reader from a first mode, wherein the reader does not operate to decode or recognize image data to a second mode, wherein the reader operates to decode and/or recognize image data.
