A method and system of high speed radio frequency communication between an outside of a metallic pipeline or vessel and an interior volume contained by the metallic pipeline or vessel includes passing a high speed radio frequency signal through a communication portal having a high speed radio frequency permittive material exposed to the interior volume of the metallic pipeline and to the outside. The high speed radio frequency signal may be transmitted from the interior volume to the outside or from the outside to the interior volume. The communication portal may be a cylindrical- or planar-shaped body connected to the metallic pipeline. A tool located within the interior volume may transmit, receive, or transmit and receive the high speed radio frequency signal. The high speed radio frequency signal may be configured according to a 2.45 GHz standard protocol.

A turf maintenance machine includes: a moveable platform configured to move the turf maintenance machine within an area to be maintained; a wireless transmitter system configured to provide a wireless energizing signal to a below-grade smart irrigation object; and a turf aeration system configured to aerate turf within the area to be maintained.

A tracer method for online monitoring of downhole zonal contributions of oil, condensate, gas, or water mass flux of a production flow in a petroleum production well, includes arranging distinct tracer carrier systems, each in different production zones in said well, the distinct tracer carrier systems arranged for releasing unique tracers to a fluid of the production zones, the tracers having affinity after downhole release to separate phases of oil, condensate, gas, or water, using an online tracer monitor, conducting sampling of tracer concentrations for at least one of the tracers in said zonal mass fluxes at a high sampling rate, based on said concentration values, estimating the corresponding zonal tracer fluxes for each delivery data point and using said one or more estimated zonal mass fluxes to control one or more Petro Technical processes.

The present invention provides a method and apparatus for laying paint indicia on a road surface, whereby the paint indicia includes magnetic elements that can be detected by at least one sensor to provide binary signals for transmission of information to a vehicle communicatively coupled to the at least one sensor. The transmission of information can be carried out regardless of a speed of the vehicle. Furthermore, the transmission of information can be carried out under all weather/visibility/road conditions.

A device for protecting crop plants (P) and/or sown seeds (S) against unwanted plants is provided to avoid the use of chemical weed control agents or herbicides. The device includes a ribbon or lace-shaped structure on which a plurality of annular elements are arranged at a distance from one another, in which the structure is designed to be applied to a cultivated surface (F) such that each element encloses the location (O) of a crop plant (P) or sown seed (S), and wherein each element includes a detectable means for marking the location concerned (O1, O2, . . . On) for detection by a machine for controlling mechanical weed control mechanisms. The device is thus an auxiliary or marking means which can be easily applied on the cultivated surface along the row of plants or seeds and allows reliable detection by machine of the locations of plants or seeds, zones to be protected.
