Abstract: A method for determining properties of a pipeline includes feeding a sound wave signal at a predetermined feed point into the pipeline so that the sound wave signal propagates in an axial direction of the pipeline. The frequency spectrum of the transmitted sound wave signal has a frequency component or a spectral range with a maximum frequency that is smaller than the lower limit frequency for the first upper mode. Reflected portions of the transmitted sound wave signal are detected as received sound wave signal and are evaluated with regard to the transmitted sound wave signal to determine at least the distance of each reflection site from the feed point.

The antenna system is operable in a first radiation mode and a second radiation mode, wherein the modes are orthogonal. The circuitry is arranged to map the first feed port to the antenna structure for the first radiation mode across a first frequency band having a bandwidth which covers one of an uplink frequency band and a downlink frequency band of the transmit/receive circuitry. The circuitry is arranged to map the second feed port to the antenna structure for the second radiation mode across a second frequency band, wherein the second frequency band covers both of an uplink frequency band of the transmit/receive circuitry and a downlink frequency band of the transmit/receive circuitry. The above concepts are extendible to more than two modes.

Abstract: A method for characterizing Coriolis gyros, in the case of which the interaction of the system comprising force transmitters, a mechanical resonator and excitation/readout vibration pick-offs is represented as a discretized, coupled system of differential equations. The variables of the system of equations represent the force signals supplied by the force transmitters to the mechanical resonator and the readout signals produced by the excitation/readout vibration pick-offs. The coefficients of the system of equations contain information relating to the linear transformation which maps the force signals onto the readout signals. The coefficients are determined by measuring force signal values and readout signal values at different instants and substituting them into the system of equations.

Abstract: A method for compensation of the zero error of a Coriolis gyro. The frequency of the read oscillation is modulated. The output signal from a rotation rate control loop or quadrature control loop for the Coriolis gyro is demodulated in synchronism with the modulation of the frequency of the read oscillation to obtain an auxiliary signal. The auxiliary signal is a measure of the zero error. A compensation signal is produced and passed to the input of the rotation rate control loop or quadrature control loop, with the compensation signal being controlled such that the magnitude of the auxiliary signal is as small as possible.
