  • Patent number: 10778166
    Abstract: An energy supply unit for a traveling wave tube is configured to transform a first voltage present at a low voltage interface into a second voltage providable at a high voltage interface. The second voltage is greater than the first voltage and corresponds to a required operating voltage of the traveling wave tube. The energy supply unit is configured to receive a signal pattern via a signal input interface and to output a control signal via a control interface to the traveling wave tube for operating the traveling wave tube based on the signal pattern and to gradually and/or iteratively align or adapt the control signal to the signal pattern being present at the signal input interface when changing an operating mode of the traveling wave tube. A power draw at the beginning of the switched-on state may increase slowly and voltage drops at the high voltage supply may be minimized.

  • Patent number: 10718655
    Abstract: A level meter and a method for monitoring the level meter operating according to the radar principle, in which a signal conductor is lead out of an inner space of a leakage chamber of a bracket housing through a process-side opening of the leakage chamber and/or of the bracket housing into the process-side outer space of the bracket housing. The method involves transmitting a signal in the form of a pulse along the signal conductor, receiving a reflected received signal, relaying the received signal to the control and evaluation unit. In addition to the simple verification of the presence of a leak, a change in the received signal can also be quantified by the frequency spectrum of the received signal being determined and monitoring of the level meter carried out in the frequency domain.

  • Patent number: 10677910
    Abstract: A system is provided for wirelessly locating objects. The system has a transceiver unit with an antenna array of two partially overlapping coils, which is used in combination with a passive electromagnetic reflector to track or locate the objects. The system is tuned to reflect and receive higher order harmonics of a transmitted signal frequency. The system is reliable in a highly reflective environment with no placement error detection due to reflections. A relatively large distance can be bridged with a minimum power and a small sensitive area to detect the coils, which increase the accuracy to determine the location of the electromagnetic reflector.
