Abstract: A system can control a transmission of a pressure signal subsea into a flowline comprising a fluid. The system can receive sensor data indicating one or more properties of a first reflection signal corresponding to the pressure signal in the flowline. The system can adjust a model based on the one or more properties of the first reflection signal. The model can be configured for determining a presence of a material deposition in the flowline. The system can determine, based on a second reflection signal and the adjusted model, a presence of the material deposition in the flowline. The system can output a command configured to initiate a remediation operation to reduce the material deposition in the flowline.

Abstract: A retractable shelter is described. In particular embodiments, a tarpaulin includes a conduit with a side wall having first and second inlets and an outlet at one end. A first lift cord may be attached near a lower edge of the tarpaulin, extend through the first set of loops, into the conduit through the first inlet, along the conduit, and then out through the outlet. A second lift cord may likewise extend through the second set of loops, into the conduit, and out through the outlet. One of more lift cords may be tied together, fastened, or braided along their respective lengths. The tarpaulin may include two or more panels equipped with loops, lift cords, conduits, and outlets. In use, the lift cords may be grasped and pulled through the outlet, raising the lower edge of the tarp toward the conduit.

Abstract: A multi-function steering column switch assembly for a vehicle comprising a mounting body (15) for attachment to a stationary part (11, 12) of the vehicle steering column assembly in use, a plurality of manually operable switch mechanisms (16, 17) secured to the mounting body, a circuit board arrangement (19, 21, 22) carried by said mounting body, means electrically connecting the contacts of said switch mechanisms with respective conductors of the contact board arrangement, active electronic components carried by the circuit board arrangement for interpreting signals generated by operation of the contacts of said switch mechanism and for generating corresponding databus messages, and, connection means on said circuit board arrangement for connecting said active components to the vehicle databus in use.
