  • Patent number: 9740903
    Abstract: An illumination light source emits illumination light toward a target to be read by image capture. An imaging assembly captures the illumination light returning from the target along an imaging axis over a field of view that extends along mutually orthogonal, first and second directions that are generally perpendicular to the imaging axis. A compound parabolic reflector receives, and optically modifies, the emitted illumination light to generate a generally uniform illumination light pattern that is substantially congruent to, and substantially overlaps, the field of view along both of the first and second directions. The compound parabolic reflector has first and second pairs of parabolic segments for respectively reflecting the emitted illumination light over first and second illumination angles along the first and second directions.

  • Publication number: 20030001015
    Abstract: All data registering devices, including voting machines, are subject to error, either from human lapses or mechanical malfunction. The object of the present invention is to disclose a device that incorporates features that immediately alert the user to the fact that an error has occurred, before it is too late or too inconvenient for the user to correct it. In voting devices that produce a machine-processable record card, such as the Votomatic and the Poll Star, votes are counted photo-electrically by shining a light through holes punched in the ballot card. According to the present invention, the greatest certainty regarding what punch-outs represent a valid vote can be obtained only if the same principle is employed to inform the voter as to whether his punch-out is or is not in the intended position and is a complete punch-out. To provide the voter with this verification, backlighting is introduced that directs a beam of light upward through each punch-out toward the voter's eye.

  • Patent number: 4176783
    Abstract: A column sensor includes a disc which is rotatably supported at one end of a lever arm and in proximity to a card reading station of a manually operable card reader. The lever arm is itself supported for rotation and biased by a spring bearing on an end of the lever arm so that a circumferential surface of the disc is urged into contact with one of the major boundary surfaces of an elongated passageway in the card reader. As a card is moved through the passageway, incremental rotation of the disc due to contact of the circumferential surface thereof with a surface of the card is detected by a light source - light detector pair mounted on the lever arm and on opposing sides of the disc, with light being coupled from the light source to the light detector through a plurality of circumferentially-spaced, axially-extending apertures in the disc so that the light detector accordingly provides an alternating electrical output signal representative of the spacing of data columns on the card.

  • Patent number: 4172553
    Abstract: An apparatus for verifying the tolerance of the positions of holes in in form of a continuous web is moved over an opaque plate on which there are a plurality of transparent areas in the form of slits. The slits in the plate are illuminated by light sources placed above the plate. Photocells are placed below the plate in position with the slits so as to be responsive to the light coming therethrough. The moving web of punched material is positioned with respect to the plate such that when the holes are in tolerance they pass between pairs of slits, thereby blocking the light from reaching the photocells. If a hole position is out of tolerance, it passes over one or more of the slits, thereby permitting the corresponding photocells to provide an output. This indicates the presence of an out-of-tolerance hole.

  • Patent number: 4154396
    Abstract: The tape in a tape reader is braked to a stop relatively slowly instead of being stopped on one character. Two sprocket reading photocells are mounted on the tape reader to provide quadrature sprocket waveforms which are applied to a bi-directional sprocket counter coupled to the address conductors of a buffer memory. The data read off the tape by the tape reader is written into the buffer memory at the addresses indicated by the sprocket counter. An output pointer counter is also coupled to the buffer memory address conductors in parallel with the sprocket counter through a time division multiplexer. During the time interval in which the output pointer counter is connected to the buffer memory address conductors, data can be read out of the buffer memory at the address indicated by the output pointer counter independently of the sprocket counter.

  • Patent number: 4150783
    Abstract: The method for reading information from a punched carrier, consists of modulating a radiation flux emitted by a radiation source by information holes of the punched carrier and then additionally modulating by an additional modulation means. The double-modulated radiation flux is then reflected by a reflector to a photosensitive input of a main converter which converts the radiation flux into a primary information signal. The primary information signal is then compared to a reference signal which changes according to the law of additional modulation, whereupon the preset signal is discriminated. The proposed device for effecting the method comprises a radiation source optically connected to a reflector through the information holes of the punched carrier, as well as through an additional modulation means. The additional modulation means can performthe functions of the reflector.

  • Patent number: 4148434
    Abstract: A method of representing decimal numbers in a quasi binary coded decimal (BCD) form is disclosed along with apparatus for using the same. The value assigned to a combination of binary bits is dependent on the location of the combination on the medium which is encoded. Use is made of the direction of motion of the medium to determine the position and hence the decimal value of specific combinations of binary bits. By interpreting certain combinations of bits in two different ways, an additional binary bit of information can be obtained from a given number of bits increasing the obtainable information from conventional BCD codes.

  • Patent number: 4142673
    Abstract: In a high speed document printing system a hole mask circuit is provided to compensate for erroneous indications of the entry of additional documents into the system due to the sensing of a discontinuity or aperture within the body of a valid document. The hole mask circuit receives a document present signal from an associated sensor and employs a retriggerable timing means to inhibit the recognition of an additional document unless the sensor has previously signaled the continuous absence of a document for a preselected time interval. The circuit is capable of discriminating between a valid document having apertures of a preselected maximum size, documents having invalidly sized apertures and spacings between successive documents.
