  • Patent number: 10436621
    Abstract: Detection for localizing at least one particle moving in a flow includes emitting a transmission signal by a transmitter, and receiving a reflected reception signal. The reflected reception signal is frequency and phase modulated in comparison with the transmission signal. The reflected reception signal is convolved with at least one kernel representative of a conjugate estimated channel pulse response. A reconstructed particle position function is formed, and the position of the particle is determined from the reconstructed particle position function.

  • Publication number: 20190212435
    Abstract: Various embodiments may include a method for monitoring a hot gas region of a gas turbine comprising: monitoring the region using an imaging radar assembly remote from the region, connected to the region with a hollow conductor. The hollow conductor is closed off at a first end proximate the radar assembly. The radar assembly operates outside the closed-off cavity and the second end opens into the region or is shielded against heat but permeable to radar waves passing into the region. The radar is actuated in time intervals wherein at least parts of the hot gas space are detected by the radar assembly repeatedly at the time intervals. The method includes: feeding acquired image data to an evaluation device; evaluating the acquired image data against a predefined maintenance requirement; and triggering a maintenance alarm as a function of the result of the evaluation.

  • Patent number: 10006992
    Abstract: A system and method for determining the relative position of stations through radio location is proposed. In one aspect, a station is configured as an apparatus having at least one antenna. At least one first station has at least one first antenna, and at least one second station has at least two base-modulated antennas. The first station sends at least one locating signal via the first antenna. The second station reflects the locating signal as a first modulated reflected locating signal via a first base-modulated antenna and as a second modulated reflected locating signal via a second base-modulated antenna. The first station receives the modulated reflected locating signals via the antenna. The phase relationships of the received modulated reflected locating signals are used to ascertain at least one position angle for the relative position between the first station and the second station.

  • Patent number: 9612321
    Abstract: In an installation including first and second components, a radar sensor that has at least two channels, each arranged to be spatially at a distance from the other, is motion-coupled to the first component, and at least two coding radar targets, each arranged to be spatially at a distance from an adjacent target, are motion-coupled to the second component. A signal is sent to each of the radar targets using one of the at least two channels of the radar sensor. At least one coded signal is respectively sent by the radar targets upon or after receiving such a signal, one of the at least two coded signals being received by one or more channels of the radar sensor from each target. The temporal relationship between at least two of the received coded signals is acquired and used to determine an angle between the first and second components.

  • Patent number: 9447773
    Abstract: An arrangement to measure deflection of a blade of a wind turbine is provided. A transmitter is arranged close to the tip end of the blade, while a receiver is arranged close to the root end of the blade. The transmitter and receiver are prepared for a wireless transfer of a monitoring signal, which is sent from the transmitter to the receiver. A monitoring system is arranged close to the root end of the blade. The monitoring system is adapted to generate the monitoring signal. The monitoring system is connected with the transmitter by a cable-bound communication line, thus the monitoring signal is transferred from the monitoring system to the transmitter. The monitoring system is connected with the receiver, thus the monitoring signal is transferred from the receiver to the monitoring system. The monitoring system is adapted to determine the deflection of the blade based on the transferred monitoring signal.
