A system, method and apparatus for training a swing movement of a club includes storing a desired swing data in a measuring device, capturing a training swing data in the measuring device, comparing the training swing data to the desired swing data to determine a set of differential data, outputting a signal to a user corresponding to the set of differential data.

System, method and apparatus for capturing and training a swing movement of a club

Novel methods are disclosed for designing and constructing miniature optical systems and devices employing light diffractive optical elements (DOEs) for modifying the size and shape of laser beams produced from a commercial-grade laser diodes, over an extended range hitherto unachievable using conventional techniques. The systems and devices of the present invention have uses in a wide range of applications, including laser scanning, optical-based information storage, medical and analytical instrumentation, and the like. In the illustrative embodiments, various techniques are disclosed for implementing the DOEs as holographic optical elements (HOEs), computer-generated holograms (CGHs), as well as other diffractive optical elements.

DOE-based systems and devices for producing laser beams having modified beam characteristics

A bioptical holographic laser scanning system employing a plurality of laser scanning stations about a holographic scanning disc having scanning facets with high and low elevation angle characteristics, as well as positive, negative and zero skew angle characteristics which strategically cooperate with groups of beam folding mirrors having optimized surface geometry characteristics. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generate a 3-D omnidirectional laser scanning pattern between the bottom and side scanning windows during system operation. The laser scanning pattern of the present invention comprises a complex of pairs of quasi-orthogonal laser scanning planes, which include a plurality of substantially-vertical laser scanning planes for reading bar code symbols having bar code elements (i.e. ladder-type bar code symbols) that are oriented substantially horizontal with respect to the bottom scanning window, and a plurality of substantially-horizontal laser scanning planes for reading bar code symbols having bar code elements (i.e. picket-fence type bar code symbols) that are oriented substantially vertical with respect to the bottom scanning window.

Bioptical holographic laser scanning system

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.

Laser scanning based bar code symbol reading system for producing a 3-D scanning volume substantially free of spatially and temporally coincident laser scanning planes

A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem 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 identification 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.

AUTOMATED METHOD OF AND SYSTEM FOR DIMENSIONING OBJECTS OVER A CONVEYOR BELT STRUCTURE BY APPLYING CONTOURING TRACING, VERTICE DETECTION, CORNER POINT DETECTION, AND CORNER POINT REDUCTION METHODS TO TWO-DIMENSIONAL RANGE DATA MAPS OF THE SPACE ABOVE THE CONVEYOR BELT CAPTURED BY AN AMPLITUDE MODULATED LASER SCANNING BEAM

Disclosed is a holographic laser scanner of ultra-compact design. The scanner has a scanner housing having width, length and height dimensions, and a holographic scanning disc for scanning and focusing a plurality of laser beams so as to produce a plurality of laser scanning planes. A plurality of beam folding mirrors are disposed about the holographic scanning disc, for folding the laser scanning planes so as to project a complex scanning pattern within the spatial extent of a predefined 3-D scanning volume. A plurality of parabolic light collecting mirrors are disposed beneath the holographic scanning disc for collecting laser light reflected from scanned code symbols. In accordance with principles of the present invention, the geometrical dimensions of the beam folding mirrors in conjunction with the geometrical dimensions of the holographic scanning disc determine the width and length dimensions of the scanner housing, whereas the geometrical dimensions of the beam folding mirrors and parabolic light collecting mirrors beneath the holographic scanning disc determine the height dimension of the scanner housing. By virtue of the present invention, it is now possible to design and construct holographic laser scanner having minimized height and width dimensions hitherto unachievable using prior art design methodologies.
