Patent CA-2127327-A1 (CA)
Title: Ultrasonic stand-off gauge
Inventor: WARNER KEVIN L
IPC: E21B47/08
Filed: 1994-07-04
Abstract: An ultrasonic stand-off gauge for use in measuring the instantaneous stand-off distance between the drill stem and the borehole wall while drilling. A primary transducer mounted on the drill collar sends and receives ultrasonic pulses between the drill collar and the borehole wall. A second, reference transducer mounted on the pressure barrel within the drill collar measures the sound speed of the drilling fluid. The drilling fluid flows through a conduit within the drill collar, where the reference transducer transmits a pulse through the drilling fluid in the conduit. The pulse from the  reference transducer is reflected off an internal reflector mounted on the internal surface of the drill collar. Since the distance between the reference transducer and the reflector is known and constant, the sound speed of the drilling fluid is determined accurately. Electronic circuitry uses the sound speed measurement of the drilling fluid as determined by the reference transducer to calculate accurate values of stand-off distance. The electronic circuitry also compensates for the variations of pressure, temperature and other characteristics of the drilling fluid, as well as for variances in the stand-off distance.

Patent CA-2148390-A1 (CA)
Title: Timing based servo system for magnetic tape systems
Inventor: ALBRECHT THOMAS ROBERT
IPC: G11B5/584
Filed: 1995-05-02
Abstract: A track following servo system is disclosed for use with magnetic tape systems in which magnetic servo track patterns contain transitions recorded at more than on azimuthal orientation across the width of the servo track. The timing of a signal derived from reading at any point across the width of such a pattern varies continuously as the read head is moved across the servo track. The pattern is read by a servo read head whose width is small compared to the servo track pattern.  The combination of a wide servo pattern and a narrow servo read head offers excellent position sensing linearity and dynamic range. In the preferred embodiment, the servo read head is also narrow with respect to the data tracks, which provides the additional advantages of superior immunity to position sensing errors caused by defects or temporal variations in the servo read head, defects in the servo pattern on the tape, wear of the head or tape, or debris collection on the head or tape. Position sensing with this system is achieved by deriving a ratio of two servo pattern intervals and therefore is insensitive to tape speed during reading. The servo patterns may include spacing intervals recognizable for error detection and correction purposes. Servo tracks are recorded using a patterned multiple gap servo write head whose magnetic gaps have geometries appropriate to generate the desired servo patterns. The patterned gaps of the servo write head are produced by photolithographically defined electroplating of permalloy on a ferrite ring head structure.

Filed: 1994-11-30
Abstract: An authentication method (30) that permits a user (12) and a file serving workstation (13) to mutually authenticate themselves. This is accomplished by exchanging a random number that is encrypted by a password (22) that is known to the user (12) and stored in a password file on the file serving workstation (13). A logon ID (21) is sent from the client workstation (11) to the server workstation (13). The stored user password (22) corresponding to the user ID (21) is retrieved from the password file. A random number is created that is encrypted by a symmetric encryption algorithm on the server workstation (13) using the retrieved user password (22), and which provides an encrypted password (24). The user (12) is then requested to enter the password (22) into the user workstation (11). The entered password (22) is used to decrypt the encrypted password (24) received from the server workstation (13) and retrieve the random number therefrom to authenticate the server workstation (13). The random number is then used as the encryption and decryption key for communication between the user and server workstations (11, 13). An encrypted message is transmitted using the random number from the client workstation (12) to the server workstation (13). The encrypted message is decrypted at the server workstation (13) to authenticate the user (11).
