摘要： A code symbol reading device includes a portable housing that contains a light source. Light from the light source is projected into a scan field external to the housing and onto a code symbol on an object located within the scan field. The light reflected off the code symbol is detected within the housing to produce scan data that is indicative of the detected light intensity. The scan data is processed to detect and decode the code symbol and to produce symbol character data that are representative of the decoded code symbol. A data packet utilizing the symbol character data is synthesized and modulated onto a carrier signal that is transmitted to a base unit where the carrier signal is demodulated and the data packet recovered. The received data packet is analyzed to recover the symbol character data, and an acknowledgment signal is produced to acknowledge the receipt of the symbol character data at the base unit.

摘要： A novel optical filtering system for a laser bar code scanner having narrow band-pass characteristics is disclosed. The optical filtering system has two different optical filtering elements which are disposed in a scanner housing in a spatially separate relationship. One of the optical filtering elements is positioned inside of the scanner housing in front of and close to the light detection element. The other optical filtering element is positioned in the light transmission aperture of the scanner housing and forms the scanning window. The optical filtering characteristics of the scanning window obscure the internal components of the scanner from plain view making the scanner appear more aesthetically pleasing. Together the optical filtering element cooperate to form a narrow-band pass filter to provide for better light collection and scanning.

摘要： Bar code symbol reading system with automatic modes of hand-held (i.e., hands-on) and stand-supported (i.e., hands-free) operation. In the hand-held mode of automatic operation, the user initiates laser scanning by simply bringing the object within at least a portion of the scan field of the automatic bar code symbol reading device. In the stand-supported mode of automatic operation, a scanner support stand is used to support the automatic bar code symbol reading device relative to a countertop surface so that the scan field is projected away from the scanner support stand and the hand-supportable housing, and extends above the countertop surface permitting the automatic reading bar code symbols on goods passed thereby. This way, during the scanner-supported mode of automatic operation, a bar code symbol on an object of virtually any size can be automatically read when the object is automatically detected in the outwardly projected scan field while the hand-supportable bar code symbol reading device is supported within the scanner support stand.

摘要： A fully automatic bar code symbol reading system which has an automatic (i.e., triggerless) portable bar code symbol reading device with an omnidirectional projection laser scanning engine mounted within the head portion of its hand-supportable housing, and an associated base unit positioned within the data transmission range of the portable unit without a physical wiring connection to the portable unit. The hand-supportable bar code symbol reading device produces a narrowly confined scanning volume for omnidirectional scanning of code symbols presented within the scanning volume, while preventing unintentional scanning of code symbols on nearby objects located outside of the scanning volume.

摘要： A laser scanning bar code symbol reading system for scanning and reading poor quality or damaged bar code symbols. The system includes a housing having a light transmission window; an extremely-elongated laser beam production module for producing an extremely-elongated laser beam having (i) a direction of propagation extending along a z reference direction, (ii) a height dimension being indicated by the y reference direction, and (iii) a width dimension being indicated by the x reference direction, where x, y and z directions are orthogonal to each other. Each extremely-elongated laser beam is characterized by an elongation ratio (ER) that is defined as Y/X>4.5 for any point within the working range of the laser scanning bar code symbol reading system, extending along the z direction; where (i) Y indicates the beam height of the extremely-elongated laser beam measured in the Y reference direction, and X indicates the beam width of the extremely-elongated laser beam measured in the X reference direction, and (iii) the beam height (Y) and the laser beam width (X) are measured at 1/e2 intensity clip level. A laser scanning mechanism is provided for scanning the extremely-elongated laser beam out the light transmission window and across a scanning field defined external to the housing, in which a bar code symbol is present for scanning by the extremely-elongated laser scanning beam.

摘要： A digital image capture and processing system includes a housing having an imaging window with an illumination-focusing lens structure integrated therewithin. A printed circuit (PC) board is mounted in the housing and has a front surface, a rear surface, and a light transmission aperture spatially aligned with the imaging window. An area-type image detection array is mounted on the rear surface of the PC board. A linear array of light emitting diodes (LEDs) is mounted on the front surface of the PC board, adjacent the light transmission aperture and aligned with the illumination-focusing lens structure. The LEDs produce a plurality of illumination beams which are transmitted through the illumination-focusing lens structure to generate a field of illumination that is projected within the FOV of the system. Illumination reflected and/or scattered off an object within the FOV is retransmitted through the imaging window and the light transmission aperture, and detected by the area-type image detection array.

摘要： A digital image capture and processing system including a housing having an imaging window; and an image formation and detection subsystem with an area-type image detection array having a periodic snap shot mode of the operation supporting the periodic occurrence of snap-shot type image acquisition cycles at a high-repetition rate, during object illumination and imaging operations. The system also includes an illumination subsystem, with a LED illumination array, for producing a field of illumination within the FOV, and illuminating the object detected in the FOV. In the illustrative embodiment, the time duration of illumination of an object within the FOV by the illumination subsystem while the area-type image detection array detects each 2D digital image frame of the object formed on the area-type image detection array, is substantially equal to the time duration that the digital image processing subsystem is allowed to process the detected 2D digital image frame and read a 1D and/or 2D code symbol graphically represented therein.

摘要： A method of capturing processing digital images of an object, using a hand-supportable digital image capture and processing system having a trigger switch, an imaging window and a field of view (FOV) projected therethrough and onto an area-type image detection array. The method involves automatically detecting an object within the FOV, and generating a first trigger event indicative of automatic object detection within the FOV. In response to the generation of the first trigger event signal, the object targeting illumination subsystem automatically generates and projects a visible targeting illumination beam within the FOV. The human operator aligns the visible targeting illumination beam with the object in the FOV, and then manually actuates the trigger switch to generate a second trigger event signal. In response to the generation of the second trigger event signal, a field of illumination is automatically generated and projected through the imaging window and within the FOV, while the targeting illumination beam is momentarily ceased, and 2D digital images of the object are formed and detected on the area-type image detection array, and one or more of the detected 2-D digital images are captured, buffered and processed, so as to read one or more 1D and/or 2D code symbols graphically represented in the one or more detected 2D digital images.
