20100161265 | 9-TERM CALIBRATION METHOD FOR NETWORK ANALYZERS - A network analyzer contains a processing device, at least one signal generator and at least four measuring points. The processing device controls the signal generator and processes measured values picked up from the measuring points. The network analyzer implements several calibration measurements on calibration standards, before it implements measurements on a device under test. The network analyzer implements the calibration measurements using the measuring points. The processing device determines error matrices on the basis of the results of the calibration measurements. The network analyzer implements measurements on the device using simultaneously, exactly three measuring points. The processing device determines measured values in each case of a fourth measuring point on the basis of the calibration measurements and the measured values of the three measuring points. The three measuring points belong to the set of the at least four measuring points, at which the network analyzer implements the calibration measurements. | 06-24-2010 |
20110077509 | MEASURING DEVICE AND A METHOD FOR DETERMINING TISSUE PARAMETERS - A measuring device provides a control device, a test-signal transmitter, a test-signal receiver and a test probe. The test probe contains at least one coaxial line. The control device controls the test-signal transmitter in such a manner that it transmits a test signal by means of the coaxial line into a given location of the tissue. The test signal is scattered by the tissue. The control device controls the test-signal receiver in such a manner that it receives the scattered test signal. The control device evaluates the received test signal. The test probe is designed in such a manner that a tissue specimen can be removed by it at the given location of the tissue. | 03-31-2011 |
20110152664 | MEASURING DEVICE AND A METHOD FOR DETERMINING MOVEMENT IN A TISSUE - A measuring device contains a microwave transmitter, a microwave receiver and a control device. The control device controls the microwave transmitter in such a manner that the latter transmits a microwave signal into a tissue. The tissue contains moving constituents. The tissue controls the microwave signal. The moving constituents of the tissue change the frequency of the microwave signal. The control device controls the microwave receiver in such a manner that the latter receives the scattered and/or frequency-changed microwave signal. The control device determines from the received microwave signal a movement of the moving constituents of the tissue. | 06-23-2011 |
20110160579 | MICROWAVE INVESTIGATION WITH A CONTRAST MEDIUM - A device for the investigation of an object uses a microwave transmitter, a microwave receiver, a control device and a contrast medium. The microwave transmitter and the microwave receiver are controlled by the control device. In one embodiment, the following steps maybe implemented:

20110166445 | MEASURING DEVICE AND A METHOD FOR MICROWAVE-BASED INVESTIGATION - A measuring device comprises a microwave transmitter, a microwave receiver, at least one antenna, a control device and a dielectric extension. The dielectric extension is disposed between the antenna and an object to be investigated. The control device controls the microwave transmitter and the microwave receiver. The microwave transmitter transmits a microwave signal by means of the antenna and the dielectric extension into the object to be investigated. The object to be investigated scatters the microwave signal. The microwave receiver receives the scattered microwave signal by means of the antenna and the dielectric extension. The length and the dielectric constant of the dielectric extension in this context are dimensioned in such a manner that the object to be investigated is disposed in the remote field of the antenna. | 07-07-2011 |
