Title: A device for measuring cathodic potential of a coated metal surface
Inventor: RDE ARILD HÃ
IPC: G01N17/04
Filed: 2014-12-17
Abstract: An ROV-operated assembly 1 includes a probe 11 provided with a probe tip 1111 arranged to penetrate a protective layer (31, Fig 5) on a metallic object (3, Fig 5). A hammer unit 14 is arranged to impart an axial motion to the probe tip where the axial motion is a reciprocating one induced by the rotation of an input driveshaft in the hammer unit. The motion may be generated by rotating a rotor with a corrugated face which rests against a complementary face of an axially displaceable non-rotatable rod connected to the probe tip. An alternative arrangement provides the rotor with a jacket having a continuous groove and a corresponding guiding element on the non-rotatable rod. The probe can be used to measure the cathodic potential of a coated metal surface by piercing the coating.

Title: Transferring data
Inventor: TROSSELL DAVID
IPC: H04L47/36
Filed: 2015-06-03
Abstract: Optimising flow, i.e. performance/throughput, from a source to a destination, for example, in a Fibre Channel based Storage Area Network comprising paths made up of a dynamic number of plural logical connections. One method is concerned with determining a optimum segment size, the segment size relating to a size of the segment (or block) provided to a transmit buffer and the segment being transmitted as plural network packets sent over respective logical connections of the path. The method comprises sending three segments of a particular segment size and then measuring performance S5 for subsequent segments sent with the same segment size. The segment size may be changed S7 and similarly performance may be measured S9 for the fourth transmitted segment at that size and for subsequent segments. Measured performances at different segment sizes may be used to determine an optimum segment size to use for still further segments. A second method (Figure 8) describes determining an optimum segment size and whilst transmitting data using the optimum size identifying an optimum input transfer size (i.e. size of data requested from a data source read into a cache), then whilst using the optimum input transfer size identifying a second optimum value of the segment size and using the optimum input transfer size and second optimum segment size value for subsequent transmission.
