  • Patent number: 4459474
    Abstract: An electronic identification system having a portable identifier with the ability to transmit by radio or audio signal the contents of an included memory upon interrogation or command to identify the user. The identifier transmits a plurality of radio frequencies intermittently to represent the memory data in digital form. The transmitted data includes a description of the proper bearer of the identifier so that a local check can be made to ascertain that the identifier is being carried by the proper person. The reader system not only identifies the bearer, but also makes a proportional recording of the transmitted data. With dual receivers and dual receiving antennas together with the proportional recording, it is possible to determine the direction of movement of the identifier through a portal into a limited access area. With proportional recording it is also possible to analyze the memory data and separate the signals from several identifiers which may have been transmitted in a time overlapping manner.

    Abstract: A system for reading binary digital data, represented by two possible spacings between abrupt flux reversals appearing on a magnetic track of a credit card, as the credit card is transported by hand by and in engagement with a magnetic head of the system. A read head having an unusually large read aperture is used to translate the two possible encoded lengths into two possible waveform amplitudes which are independent of transport speed. Then, by means of amplitude discrimination, the "0" bits are detected; and by zero slope detection, the "1" bits are detected. Mechanically, the read head is located centrally in an obtusely angled long side of a housing and is opposed by a contoured Teflon pillow that substitutes for one-half of the usual card slot. This unidirectional pillow is shaped and spaced from the head so as to cause the credit card to be slightly bent around the head's face in passing.

  • Patent number: 4239959
    Abstract: A uniformly distributed magnetic recording medium is carried on or in an initially fluidizable support. During or after magnetically writing information upon the medium, the support is changed to a fluidized state, sufficient to permit some physical translational movement of the medium in localized areas corresponding in pattern to characteristic magnetic non-uniformities caused in medium by the magnetic writing. The support is then set or otherwise converted to a state in which such movement is no longer possible. Thereafter, even if the medium is degaussed, the now set non-uniformities in physical distribution of the recording medium, will permit the information that had been magnetically written, to continue to be read e.g. by magnetic analysis of the medium.

  • Patent number: 4239151
    Abstract: This specification describes apparatus for reading and decoding data encoded in terms of the spacing between adjacent code bars on a document. The apparatus contains reading means for producing an electrical pulse for each bar recorded on the document as the bar passes the reading element. A counter is used to measure the time between each two pulses and the resultant counts are stored in a memory in the order in which the pulses were produced by the reading means. A microprocessor then compares this stored data with microcoded data representative of properly coded digits. If there is a compare the stored data is shifted out of the memory and into a computer for use. However if there is a no-compare the microprocessor alters the data on the assumption that a particular type of error has occurred and again compares the modified data with the microcoded data. If this results in a compare the modified data is again read out and into the using computer.

  • Patent number: 4213039
    Abstract: A dynamic card reader adapted for use in reading information magnetically recorded on a card in two rows or tracks parallel to the longer dimension of the card. The information is read as the card is being inserted into the slot by two Hall effect sensors disposed in side-by-side relation at the entrance to the card slot. One row of magnet information generates a data signal and the other row generates a clock signal which is used to strobe the data signal into a shift register. The Hall sensors are connected to the detection circuitry through differentiating capacitors, such that the detection circuitry is responsive to transition of magnetic polarities as the card is inserted into the slot.

  • Patent number: 4197988
    Abstract: This invention discloses a magnetic stripe card reader/writer apparatus comprising a card reader/writer device and a basic interface circuit. The recording head of the card reader/writer device is mounted on the end of a sensor arm and is driven over the magnetic stripe in an arcuate path by a head drive motor. The card reader/writer device includes a unique card locking mechanism which allows insertion of the card in only one manner and locks the card in place before initiating the reading or writing operation of the device. The interface circuit controls the forward and reverse motion of the head drive motor, converts magnetic data previously recorded on the card into digital information and records digital information onto the magnetic stripe card in the form of magnetic data.

  • Patent number: 4193099
    Abstract: The recorded content of a magnetic card is transferred directly to a magnetic tape simply by bringing the magnetic card into contact with the magnetic tape and applying a magnetic field to the contacting area with the aid of a copy magnet or a magnetic printing head energized by D. C. current or A. C. current, on the condition that the coercive force of magnetic material on the card is larger than that on the tape, and a reproducing head mounted along the path of the tape reproduces the transferred content. Thus, the recorded content of a magnetic card can be reproduced many times just by engaging the card in the device once.

  • Patent number: 4183254
    Abstract: A drive reducer for a tape recorder accomplishes a large reduction from the surface speed of a motor-driven shaft to the surface speed of a drive element for advancing a tape media such as a magnetic recording tape on a flat card. A cup-shaped element is fixed to a reducer shaft and positioned so that the inner surface of a cylindrical outer wall engages the motor-driven shaft. An idler wheel freely rotatable on the reducer shaft is positioned radially inside the cup-shaped element and is formed of compressible material with a diameter large enough for compressibly engaging the motor-driven shaft and pressing it against the inner surface of the outer wall of the cup-shaped element. Rotation of the reducer shaft is transferred to the driven element preferably by a friction sleeve on the reducer shaft and a friction disk engaging the sleeve and turning a shaft supporting the driven element.
