Abstract: Systems and methods for locating buried utilities in conjunction with associated electro-magnetic marker devices are disclosed. A marker device may include a marker device antenna and an electronic circuit operatively coupled to the marker device antenna. The electronic circuit may include at least two resonant circuits, including a first resonant circuit formed in combination with the marker device antenna for receiving an excitation signal at a first frequency from a marker excitation device. The received excitation signal may be converted into a power supply by a power circuit for powering the electronic circuit. Responsive to the received excitation signal, a processing element provided in the electronic circuit may generate an output signal at a second frequency, which is substantially different from the first frequency. The generated output signal may be tuned by a second resonant circuit and provided to the marker device antenna.

Abstract: Die Erfindung betrifft ein Verfahren und einen Umrichter zur Lokalisierung einer an dem Umrichter (U) angeschlossenen elektrischen Maschine (M) oder zur Identifizierung des an der elektrischen Maschine (M) angeschlossenen Umrichters (U). Dabei wird mittels eines Leistungsausgangs des Umrichters (U) die elektrische Maschine (M) mit einem elektrischen Signal beaufschlagt, wobei das elektrische Signal eine derartige Amplitude, Phase und einen derartigen Signalverlauf aufweist, dass die elektrische Maschine (M) zur Abgabe einer mechanischen oder akustischen Schwingung oder zum Aufbau eines magnetischen oder eines elektrischen Feldes in ihrer Umgebung angeregt wird. Dadurch ist es möglich, die jeweilige an dem Umrichter angeschlossene elektrische Maschine berührungslos zu lokalisieren und das Signal und damit auch den das Signal sendenden Umrichter zu identifizieren.

Abstract: Systems and methods for a composite magnetic field sensor is disclosed. The electromagnetic survey system includes a first receiver configured to sense signals in a first spectrum based on sensing a magnetic field. The system includes a second receiver configured to sense signals in a second spectrum based on sensing a time rate of change of the magnetic field. The second spectrum has a frequency range higher than the first spectrum. The system further includes a transmitter configured to transmit a specified waveform and a control system configured to control the transmitter to transmit the specified waveform. The control system is also configured to receive signals sensed by the first receiver, receive signals sensed by the second receiver, and store the signals received from the first receiver and the signals received from the second receiver.
