  • Patent number: 11947001
    Abstract: A measurement setup for measuring attenuation through an irregular surface of a device under test is described. The measurement setup includes a positioning system, a reference reflector, and a three dimensional imaging system. The measurement setup has a reference state and a measurement state, wherein respective images are taken in the different states. The imaging system is configured to compare the images taken in the reference state and the measurement state to determine the attenuation of the device under test. Further, a reference reflector as well as a method for measuring attenuation are described.

  • Patent number: 10222466
    Abstract: The present disclosure relates to a method for the registration of a 3-dimensional all-round view of a moving human or animal body surface. The method accordingly comprises the steps: determination (A) of a movement velocity of at least one region of the body surface and registration (B) at least of the region of the body surface at a timing point at which the value of the movement velocity of this region falls below a defined threshold value.

  • Patent number: 9391719
    Abstract: A method for determining the place of origin of a passive intermodulation product excites a distributed device under test with two first excitation signals (x1(t), x2(t), each with a single spectral line, of which the frequencies (f1, f2) provide a frequency spacing relative to one another. Following this, the phase (?IM3Meas) of a first passive intermodulation product generated at the place of origin in the distributed device under test from the first excitation signals ((x1(t), x2(t)) by nonlinear distortion is measured, and the delay time of the first passive intermodulation product from the place of origin to the measuring device is calculated from the measured phase (x1(t), x2(t)) and the frequency (2·f1?f2) of the first passive intermodulation product. Finally, the place of origin of the passive intermodulation product is determined from the delay time and the topology of the distributed device under test.

  • Patent number: 9268018
    Abstract: The present disclosure provides a method and a corresponding device for extending the illumination of an object under investigation. The object under investigation is illuminated with an electromagnetic microwave signal which is transmitted from a transmission antenna. The microwave signal reflected from the object under investigation is received by at least one reception antenna. An image of the object under investigation is reconstructed through synthetic focusing of the reflected microwave signal.

  • Patent number: 9265151
    Abstract: A printed-circuit board arrangement electrically connects the at least one transmitter and/or receiver unit with at least one antenna element, whereas the at least one transmitter and/or receiver unit and the at least one antenna element are at least partially integrated into the printed-circuit board arrangement. In this context, the printed-circuit board arrangement includes different printed circuit boards, which are mechanically connected to one another in a rigid manner. A first part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a first material which is suitable for high-frequency, and a second part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a second material different from the first material, which is still sufficiently suitable for a low frequency and/or for a direct-voltage range.

  • Patent number: 9091724
    Abstract: A measuring device provides a synthesizer device, at least two controlling devices and at least two controlled oscillators. The synthesizer device contains at least one direct digital synthesizer and generates at least two signals of known phase ratio. Signals generated by the synthesizer device form reference signals of at least one controlling device. Signals formed by the controlling devices control the controlled oscillators. The measuring device contains only frequency splitters, which divide by integer division factors.
