Abstract: A system for communicating over a power cable has a power line connected to a power source at one end, a switch mode transformer connected to the power line at the other end for transforming voltage received from the power source through the power line, modulation of the switch mode transformer, and a receiver situated at the power source end and adapted to detect and process ripple signals from the switch mode transformer propagated on the power line.
Abstract: A system for communication through subterranean structures underneath a surface comprises at least one exploration tool adapted to penetrate into the underground, at least one transmitter, at least one receiver, and signal transfer means for transmitting signals between the exploration tool and a recording unit arranged overground, where at least one of the transmitter or receiver is integrated in the exploration tool. The exploration tool is a device which is able to penetrate into the underground in order to bring equipment into the underground independent of any existing or new wells.

Abstract: A high voltage transformer for cascade coupling wherein the high voltage transformer comprises a primary winding, a high voltage winding and a transformer core, and wherein the primary and high voltage windings encircles concentrically at least a part of the transformer core, and wherein the high voltage transformer is provided with a secondary winding, as the high voltage winding comprises one or more single layers connected in parallel.
Abstract: Method of introducing instruments/measuring equipment/tools into formations (9) in the earth's crust or other solid materials, such as ice, by means of a drilling device (1), material being liberated by, for example, rotation of a drill bit (2), or by melting, for example by means of a heating element, the liberated material thereafter flowing, or being pumped, past/through the drilling device (1) and being deposited in the bore hole (18) above/behind the drilling device (1). A drilling device (1) for practising the method described above, comprising necessary components, for example a drill bit (2), a driving motor (4), and a steering/control component (7), the drilling device (1) being provided with a cable magazine (10) containing a cable (12), and possibly with an output feeder (11).
