  • Patent number: 5061845
    Abstract: A shell having symmetrical top and bottom parts form a chamber containing a substrate carrying package semiconductor devices and a connector. A cover fits in a hollow of the top part normally for its top surface to rest flush with the top surface of the top part. The packaged semiconductor devices on the substrate extend through apertures in the top part with the top surfaces of the packaged semiconductor devices resting substantially flush with the top surface of the top part. The cover flexes over the packaged semiconductor devices at those locations. Gripping means occur in the ends of the shell opposite the connector to aid removal of the memory card from a desired port and an interior wall and side pockets provide stress relief for removal and insertion of the connector in the desired port.

  • Patent number: 5055662
    Abstract: A portable prepaid card is disclosed comprising a substrate on which a photoconductive layer, a liquid crystal layer, and a transparent electrode plate are built up in this order. When an optical image is radiated on the photoconductive layer through the liquid crystal layer, the exposed regions and the unexposed regions of the photoconductive layer have different volume resistances. In this state, if a predetermined voltage is applied from the outside between the electrode plate and the photoconductive layer, a visible image corresponding to the radiated optical image is fixed in the liquid crystal layer.

  • Patent number: 5055659
    Abstract: A system for reading from and for writing data into electronic tags which may be associated with objects which are moving with respect to an interrogator, or may be located in fixed positions in the path of a moving interrogator. The interrogator, which is stationary if the tag is moving, sends a continuous RF signal to the remote tag. The tag backscatter-modulates the received RF signal with data temporarily or permanently stored in the tag, including, for example, data associated with the object to which the tag is attached, for example, its identity or contents. The system of this invention uses a very efficient encoding technique for the data which is backscatter-modulated by the tag and received by the interrogator. The backscatter-modulated signals are made up of signals of first and second frequencies f.sub.1 and 2f.sub.1, respectively, where the second frequency 2f.sub.1 is twice the first frequency f.sub.

  • Patent number: 5051566
    Abstract: The IC card reader includes card positioning and guide means and contact elements which provide electrical connections with conducting areas on the IC card, via which circuits are established with the apparatus in which the IC card reader is incorporated. The card reader includes, in particular, a carriage (8) which is moveable relative to a contact frame (3), having a rest position that it occupies when there is no card in the reader, being urged into its rest position by return means (RA), and an actuated position into which it is thrust by a card (100) inserted in the reader. The carriage (8) is arranged to co-operate with the contact elements (35, 36) in such a manner that when in its rest position, the carriage (8) causes the contact elements (35, 36) to be held in a rest position in which they lie off the insertion path (62) of a card, and when in its actuated position, the carriage (8) causes the contact elements (35, 36) to bear against the contact positions of the card.

  • Patent number: 5034596
    Abstract: An IC card processing apparatus has a data reading/writing unit which accepts an IC card and electrically connects the IC card with terminal equipment. Data is exchanged with the IC card and/or the data reading/writing unit. To shorten the time for processing data of the IC card processing apparatus, the terminal equipment directly exchanges data with the IC card. To achieve this, the data line of the terminal equipment is connected to the data line of the IC card. Before using the IC card for transactions, the data reading/writing unit feeds a personal identification number (PIN) to the IC card for identifying the PIN information. To prevent the PIN information from being delivered to the terminal equipment, a switch is provided between the data line of the terminal equipment and the data line of the IC card. While identification of the PIN information is underway, the switch remains totally open, preventing reception of the code by an unauthorized party.
