  • Patent number: 7152796
    Abstract: A holographic laser scanner of ultra-compact design capable of reading bar and other types of graphical indicia within a large scanning volume using holographic optical elements and visible laser diodes. The holographic optical elements are arranged on the scanning disc in such a manner so that none of the laser scanning planes generated within the 3-D scanning volume of the system are spatially and temporally coincident with any other laser scanning plane within the 3-D scanning volume. This novel feature of the present invention ensures that there is substantially zero cross-talk at the plurality of photodetectors provided within the system, significantly improving the performance of the system.

  • Patent number: 7143943
    Abstract: Methods of and systems for illuminating objects using planar laser illumination beams (PLIBs) having substantially-planar spatial distribution characteristics that extend throughout the field of view (FOV) of image formation and detection modules employed in such systems. Each PLIB is produced from a planar laser illumination beam array (PLIA) comprising a plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD), a focusing lens, and a cylindrical optical element arranged with each PLIM, which is adjustable relative to other PLIMs so as to permit precise positioning of each PLIM relative to the optical axis of the imaging optics of the image formation and detection module. The individual PLIB components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system.

  • Patent number: 7140543
    Abstract: A device including at least one image detection array and image formation optics that provide a field of view corresponding to the image detection array. At least one illumination module (which includes at least one source of coherent illumination) produces planar light illumination that substantially overlaps the field of view corresponding to the image detection array. Illumination control circuitry modulates the power level of illumination produced by the source of coherent illumination during each photo-integration time period of the image detection array to thereby reduce speckle noise in images captured by the image detection array. The illumination control circuitry preferably modulates the power level of illumination by controlling the number and/or duration of time periods corresponding to different power levels of illumination produced by the source of coherent illumination during each photo-integration time period of the image detection array.

  • Patent number: 7137561
    Abstract: Disclosed is an automatically-activated wireless code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner.

  • Patent number: 7112200
    Abstract: An electro-cauterizing cannula assembly for use in a power-assisted liposuction instrument having a hand-holdable housing and a mechanism for reciprocating the cannula assembly. The electro-cauterizing cannula assembly includes an inner and an outer cannula, each having a distal and proximal end and at least one aspiration aperture about the distal end. The inner cannula is disposed within the outer cannula and the inner and outer aspiration apertures are in at least partial registration to form an effective aspiration aperture. During aspiration of tissue, high-voltage RF power signals are supplied to the inner and outer cannulas to effect hemostasis about the reciprocating aspiration aperture. Such hemostasis is achieved by causing protein molecules within aspirated tissue to coagulate in response to the high-voltage RF signals being supplied across the reciprocating cannulas. The cannula assembly is releasably detachable from the hand-holdable housing to facilitate cleaning and sterilization of the same.

  • Patent number: 7111786
    Abstract: An automatically-activated wireless code symbol reading system comprising a hand-supportable housing having a manually-activatable data transmission switch under automatic communication range dependent control. When a bar code symbol is read, the bar code reader is located inside the predetermined RF data communication range of the system, then the symbol character data string, produced at substantially the same time as the manual activation of the data transmission switch, is transmitted to the base station over the wireless RF communication link. If the device is outside the range, then an audible and/or visual indication is automatically generated, and the packaged symbol character data string is packaged and transmitted to a data storage buffer aboard the bar code reader. Then when the bar code symbol reader is moved within the communication range of the system, the buffered/packaged symbol character data is automatically transmitted to the base station by the RF-based data communication link.

  • Patent number: 7104453
    Abstract: A fully automated package identification and measuring system (300), in which an onmidirectional holographic scanning tunnel (100) is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem (500, 600) is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identificaton data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.
