Title: Personal identification system
IPC: G06Q20/40
Filed: 1979-08-16
Abstract: A method and apparatus for verifying that the bearer of a card (e.g., credit card, bank card, etc.) is authorized to use the card. The card bears machine-readable indicia of an account number (PAN) and the bearer of the card has memorized a personal identification number (PIN). There is associated with the PAN a check number (PCN) which is derived by (1) generating a first cipher Y1 by encrypting the PAN using the PIN in combination with a secret security number as a key, the bits of which address a data encryption process (2) generating a second cipher by decrypting the first cipher using the secret security number as a key so that the decryption process is the reverse of the encryption process and (3) storing the second cipher as the check number PCN in a machine-accessible location, which may be in a separate memory or recorded on the card itself. Verification is accomplished by (a) sensing the PAN from the machine-readable indicia on the card (b) enciphering the PAN with respect to the data encryption process under control of a key which is a combination (such as by addition) of the PIN and the secret security number to thereby produce a third cipher (c) sensing the PCN from the machine-accessible location (d) enciphering the PCN with respect to the data encryption process under control of a key which is the secret security number to thereby produce a fourth cipher and (e) accepting the card as valid provided the third and fourth ciphers bear a predetermined relationship to each other, such as equality.

Title: Device for measuring and methods for adjusting the convergence of the electron beams in color display tubes
IPC: H04N9/28
Filed: 1980-05-02
Abstract: A device for and methods of measuring and adjusting the convergence of the electron beams in a color display tube of the shadow mask type. The device includes a detector in the form of a divided photosensitive cell comprising at least two separate photosensitive surface parts which are situated symmetrically relative to the center of the cell. The photosensitivity of the surface parts increases substantially from the center of the cell. In use the device is mounted so that the detector is on the central area of the display screen. Three lines are produced in one deflection direction of the tube by means of the three electron beams with one video signal. The central line and detector are moved relative to each other until the longitudinal axis of the line coincides with the center of the cell. Then either the distances from the axes of the other two lines to the axis of the center line are measured by determining the differences of the incident light impinging on the two separate surface parts and the measurements are stored for subsequent use or the static convergence unit of the tube is adjusted until all three lines coincide. The method is repeated for three lines extending in the other deflection direction.
