摘要： An adaptive optics phoropter is aligned with a Badal optometer and an adjustable aperture component to subjectively determine an optimal vision correction as a power profile for an ophthalmic lens or ablating a cornea. The optimal power profile is preferably determined in an iterative process by adjusting the vergence of the Badal optometer and aperture size of the adjustable aperture component for power profiles with presbyopic power zones having different amplitudes, shapes, widths, and/or de-centering. Also included is a method of recursively computing a refractive surface with a regular presbyopic power zone (e.g., according to the optimal power profile) and adding it onto an underlying irregular Zernike-basis-set aberration-corrected surface in a linear fashion for fabricating an ophthalmic lens.

摘要： Techniques for determining a position for a rotating optical element, or spinner, of a bar code scanner are described. A diffractive element is positioned so as to be struck by a laser beam produced by a laser source and reflected from the spinner when the spinner is in a reference position. The diffractive element diffracts the reflected beam to produce a diffracted line which strikes a reference position photodetector, thereby causing the reference position photodetector to produce a reference position photosignal. The reference position photosignal can be read by a controller to determine when the spinner is in the reference position and used by the controller as a signal to deactivate the laser source. The position of the spinner during its rotation can be computed based on the speed of the spinner and the time elapsed since the occurrence of the reference position photosignal, and the laser source can be activated when timing information indicates that the spinner is in an appropriate position to begin a single line scan pattern and deactivated when the reference position photosignal indicates that the spinner is in the correct position to terminate the single line scan pattern.

摘要： A bar code scanner includes a window and a rotary spinner mounted therebelow having a plurality of circumferentially adjoining mirrored facets for sweeping light along a scanned arc. A light source projects a scan beam on the spinner, and a plurality of pattern mirrors are optically aligned with the spinner along the scanned arc in a forward path for diverting the scan beam outwardly through the window to a bar code for effecting a scattered beam therefrom. A collection mirror is optically aligned with the spinner along the scanned arc for receiving the scattered beam in a return path from the pattern mirrors and spinner in turn. A detector is optically aligned with the collection mirror for receiving the scattered beam, and a decoder is provided for decoding the scattered beam.

摘要： The present invention provides a system, method and apparatus for identifying a product through reading of the product label by a retail terminal. The product/product label is scanned by an imager of a retail terminal. An attribute recognition program such as an optical character recognition (OCR) program is used on the scanned product label which generates text strings from alphanumeric label information and graphics maps/images from graphics/logos. Text strings and/or graphics data are then compared to various text strings and graphics data in a database or look-up table to return information relative to the scanned text string(s)/graphic(s). In one form, kiosks, incorporating an imager and the necessary hardware and software to scan a product label and process the scanned information in accordance with the present principles, may provide printouts of product information, instructions, order forms or the like for the scanned product. Additionally, standard queries or user-generated queries may be answered relative to the scanned product label. Data, stored either locally or at a remote site accessible via a network or the like, is correlated to a plurality of text strings/graphics that correspond to alphanumeric text/graphics on a plurality of product labels.

摘要： A method for optimizing the reading ability of an omnidirectional optical scanner for various bar code label aspect ratios which can effectively double the angular coverage of an ordinary scan module. For high aspect ratio bar code labels, the method involves increasing the speed ratio between a first scanner motor within a scan module and a second scanner motor within a tilted mirror assembly by decreasing the speed of the second scanner motor by a predetermined amount. For other bar code labels, the method involves decreasing the speed ratio between the first scanner motor and the second scanner motor by increasing the speed of the second scanner motor by the predetermined amount. The method uses programming tags and speed control circuitry to change the speed of the second motor. The method also includes the steps of decreasing the swipe speed of articles having high aspect ratio bar code labels and increasing the swipe speed of other articles.

摘要： A portable bar code scanner includes a housing member having a supporting surface which includes an aperture extending in a horizontal direction through the housing member. The supporting surface includes a recessed portion which is in communication with the aperture and which supports a portable bar code scanner. A mirror member mounted within the aperture and at an angle to the supporting surface deflects the scanning light beams through the aperture for scanning coded indicia positioned adjacent the aperture. A second embodiment discloses a support member slidably positioned within the aperture from either end of the aperture in which is mounted a mirror member for deflecting the scanning light beams through the support member and the aperture.
