Abstract: An imager (30) for illuminating and imaging encoded symbology to facilitate decoding of the symbology and which provides both 'bright field' and 'dark field' illumination patterns is provided with an illumination directing device to direct the 'bright field' illumination pattern into an alternative 'dark field' illumination pattern. In one embodiment the illumination directing device takes the configuration of a disc that is selectively positionable in front of the imager (30) and removable therefrom depending upon whether or not the illumination pattern is to be changed. The disc snap fits into a position at the front of the imager housing (32) and includes a fresnel configured outer ring, a light blocking inner ring, and a light transmissive center. The fresnel configuration (520) receives light and redirects the light forward of the imager and towards a centerline passing through the device to provide the alternative illumination pattern.

Abstract: A system for imaging an object is described. The system includes a light source (200) for illuminating the object (210) with light, the light from the light source (200) having a first wavelength. The system further includes an image capturing device (240) and a filter device (220). The filter device (220) is transmissive for light having a wavelength which is different than the first wavelength, and reflective for light having the first wavelength, the image capturing device (240) capturing an image of at least a portion of the object (210) using light transmitted through the filter device (220). The system may further include a dark field illumination system (400) for illuminating the object (210) either simultaneously with the illumination by the first light source (200), or sequentially with respect to the illumination by the first light source (200).

Abstract: A system for simultaneously obtaining (PD1-n) a plurality of images of an object (501) from a plurality of different viewpoints. With such a system, bright-field images and dark-field images may be simultaneously obtained. This is accomplished by positioning a plurality of light receiving devices (PD1-n) are spaced substantially equally along at least a portion of a surface of an imaginary hemisphere surrounding the object. Another aspect of the invention generates composite images from simultaneously obtained images. Equivalent regions of each image, corresponding to geographically identical subpictures, are compared. The subpicture having the highest entropy is selected and stored, with the process continuing until all subpictures have been considered.

Abstract: A multiple output reel module includes a reel wheel (50) supporting a plurality of spindles (116). Mounted to each spindle is a reel (74). The reel wheel is rotatable to position one of the spindle and reel combinations in a loading position in which output media (16) from a nearby machine is interconnected to the reel. The spindle and reel are rotated to load the reel with output media (16). A CPU monitors the status of the reel, and stops the loading when the reel is full. The CPU then rotates the reel wheel to position a second spindle and reel combination in the loading position. The output media is automatically positioned over a portion of the second reel, and the output media is automatically interconnected to the second reel with an over-center finger assembly (248). Then output media between the two reels is cut and the second reel is loaded with output media.

Abstract: A method of operating a charge coupled device in an accelerated mode is provided, and in particular in connection with an optical symbology imager (10), so as to minimize variations in the position of the imager relative to the code. The CCD (93) has two horizontal shift registers, each receiving every other scan line so that the output of each horizontal shift register equals the number of scan lines for normal television signals (262). The method skips through multiple lines of image data (fig. 22), then provides a black reference signal then images a series of lines at a slower speed, these lines being the lines of interest (fig. 23) for focusing and illumination operations in the optical symbology imager. Finally, the remaining lines are passed through quickly. The imager goes back into reset mode after either normal or fast mode operation, and is thereby immediately ready to perform another scan. The fast mode operation enables the imager to obtain the approximately ten lines of image data of concern in only approximately 5.5 milliseconds, a significant time savings. This operation can be performed for some or all of the multiple optical positions.

Abstract: Diffuse 'dark field' illumination (90) and 'bright field' illumination (162, 164) are each provided for a hand-held encoded symbology imager/reader; to be projected therefrom upon symbology disposed on a target (component part, goods, package, etc.). The imager/reader (30) is encased in a housing ergonomically configured to be gripped in more than one manner and to thus facilitate holding the imager/reader steady. The symbology to be imaged (40, 42, 44) is targeted by a line that not only spots the symbology, but by extending a length commensurate with that of the symbology, indicates that the symbology is in the field of view of the imager/reader. A CCD (252), disposed to receive light reflected from the symbology, has its readout controlled so that only selected portions of the CCD need to be analyzed for illumination and focusing purposes. To optimize imaging and decoding time, and to optimize use of power, readout from some portions of the CCD is accomplished in relatively rapid time by speeding up the readout of the CCD in some of its active area; while reverting back to a slower readout for data to be analyzed for illumination and focusing control and decoding purposes. In addition, special application of entropy principles facilitate determining the optimum focus and illumination conditions for the imager/reader.

Abstract: In a method for defining the spatial location of points comprising an object surface, radiant energy is projected onto the object (10) in successive steps with the energy projected in each step having a unique change in intensity with distance along an axis (TA) extending transversely of the projection field. The spatial locations of surface points (P 1 , P 2 , P 3 , P 4 ) are derived by comparison of reflected intensity information derived from records (20) of the object so irradiated and predetermined patterns derived in accordance with the intensity changes with transverse distance in the respective energy projections.
