  • Patent number: 7344071
    Abstract: A voting system for storing voter input data on a voter selection card, which is capable of storing data for a plurality of candidates, and the system, subsequently, prints a ballot marked in accordance with data on the voter selection card. A voter-assist terminal receives a blank voter selection card, and then presents candidate selection options to the voter visually by means of an LCD touch screen menu and aurally by means of a synthesized speech menu. Candidate selections entered by means of the touch screen menu or by means of the audio menu are stored on the voter selection card, and the voter selection card is returned to the voter to take to a reader terminal. The reader terminal sends the stored data on the voter selection card to an attached printer which prints a marked ballot corresponding to the voter's selections. The ballot is inserted in a ballot scanning device, wherein the ballot is tallied and deposited in a locked ballot box.

  • Patent number: 7275693
    Abstract: 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.

  • Patent number: 7264169
    Abstract: A security mark having multiple optically orthogonal coaligned bar codes is produced using a reflection hologram visible substantially at only a first wavelength that is layered over a wavelength sensitive filter, which blocks light transmission at the first wavelength but transmits light at a second wavelength, and having beneath it an additional bar code visible through the hologram and the wavelength sensitive filter at the second wavelength. A validation means reads multiple holographic bar codes with light at the first wavelength by illuminating the hologram separately from multiple directions, and further reads the bar code beneath the wavelength sensitive filter by illuminating the mark with light of the second wavelength. By suitable choice of multi-directional and multi-wavelength illumination, multiple coaligned bar codes may be read in the same physical location with no mutual interference.

  • Patent number: 6119943
    Abstract: A substrate capable of receiving and retaining imaging is coded so as to maximize the amount of the scannable information that can be packed into an area, and/or to provide an effective security feature. A first machine readable identification code (e.g. bar code) is imaged on a predetermined area of the substrate, and is opaque to a first predetermined wavelength range of electromagnetic energy (e.g. the infra-red region of light). An overlay is applied over and at least partially covering the first code. The overlay is transparent to the first wavelength range, and opaque to a second wavelength range (e.g. the visible spectrum of light). The overlay may be a security block which substantially completely covers the first code, or may be a second bar code (or additional codes) which is transparent to the second range.

  • Patent number: 6105863
    Abstract: A method of processing transaction charges from continuing billing arrangements that allows such charges to continue to be authorized after the account number to which the charges are directed has been invalidated, such as would result if the account number related to a credit or debit card that was lost, stolen or expired, or to a checking or savings account that was closed or transferred. A security key is used to indicate charges that are to be authorized after the account number has been invalidated. Charges that include the key are authorized, while charges that do not include the key are rejected.

  • Patent number: 6098885
    Abstract: A bar code scanner for stationary disposition at a counter to projecting a scanning pattern comprising first, second, third, fourth and fifth groups of parallel scan lines within a relatively narrow, yet diverging, volume, e.g., pyramid, cone, etc., centered about a projection axis. The scanner includes a compact housing mounted on an adjustible base. The housing includes a window, five stationary mirrors, a laser diode, a rotating reflective polygon for sweeping the laser beam from the diode across the mirrors and out a window so that the projection axis is substantially but not precisely perpendicular to the window. The scanner also includes a fixed curved collecting mirror and a concentrating lens to focus light which is reflected off of a bar code to a photodetector. One mirror extends along an axis parallel to the transverse axis to produce the first group of scan lines.

  • Patent number: 6073848
    Abstract: The present invention relates to a multi-stage digital Automatic Gain Control (AGC)circuit for selectively sampling the outputs of a serially connected amplification stages and for selectively controlling the gain of one or more stages in order to keep the amplitude of the final stage output within a predetermined range. The AGC provides a "quick" adjustment to overall system gain so that the system can produce a regulated signal within a short period of time, thereby improving the regulation response time. The AGC includes a number of serially connected amplification stages, and a gain controller. The output of each amplification stage, in addition to feeding the next amplification stage, is also an input to the gain controller. The gain controller receives the amplification-stage outputs, processes the outputs, determines the required gains of the various amplification stages and adjusts the gains via a number of gain control signals.

  • Patent number: 6062481
    Abstract: Bar codes, comprised of black and white stripes, are shown to be a finite topic, and the optimum bar code methodology is binary coded binary, BCB. Binary digits are utilized to represent bar coded messages and each binary digit is immediately complemented, forming two independent but binarily complemented messages in one bar code symbol. BCB represents given information in less space than, e.g., Interleaved 2 of 5 and Code 39, while using the same x width (the width of a module), and BCB is far more versatile and is easier and less expensive to print and scan. BCB avoids misreads more reliably and achieves a dramatically higher first time read rate through use of error correcting bar codes.

  • Patent number: 6047893
    Abstract: A method wherein an image of an object bearing an optical code is divided into a number of elementary images for which a brightness gradient vector is calculated. The calculated gradients of a magnitude above a given threshold value (Glim) are transformed to eliminate the information relative to the direction of the vector, while maintaining the information relative to the path of the vector. The transformed and quantized vectors of a subimage including a number of elementary images are added to calculate a total gradient vector, which is compared with reference values to select significant subimages containing a sufficient number of gradient vectors of substantially the same path.
