摘要： A method for operating a vibrating gyroscope, wherein the vibrating gyroscope is used as a resonator and forms part of at least one control circuit that excites the vibration gyroscope by feeding an excitation signal with its natural frequency. An output signal can be tapped from the vibrating gyroscope from which the excitation signal is deriveable by filtering and amplification. Upon switching on a sensor arrangement that includes such a vibrating gyroscope, the frequency of the excitation signal is adjusted by exciting the vibrating gyroscope, before the excitation signal is fed, to oscillate freely, measuring the frequency of the free oscillation and feeding the excitation signal to the vibrating gyroscope with the measured frequency.

摘要： A method of testing an agent for its potential at modulating induction of a molecular weight change of a first polyion is disclosed. The method is effected by (a) subjecting the first polyion to conditions under-which the first polyion undergoing the molecular weight change in a presence, in an absence or under several different concentrations of the agent; (b) interacting the first polyion with a second polyion having an opposite charge, the second polyion being fluorescently labeled; (c) providing reaction conditions so as to allow molecular weight discriminative interaction between the first polyion and the second polyion; and (d) employing a fluorescence polarization assay for determining a modulating effect of the agent on the induction of the molecular weight change of the first polyion.

摘要： The invention relates to a method for determining a rate of rotation, in which, as a function of a primary actuating signal (E_PRIM), a sensor element (2), the natural frequency (FE) of which is linearly dependent on its temperature (T), is excited so as to perform a primary oscillation along a first axis (AXIS—1). A primary measurement signal (A_PRIM), which is representative of the primary oscillation, is determined. Also, a secondary measurement signal (A_SEC) is determined which is representative of a secondary oscillation of the sensor element (2) along a second axis (AXIS—2), which together with the first axis (AXIS—1) encloses an angle that is unequal to zero. The natural frequency (FE) of the sensor element (2) is determined. On the basis of the determined natural frequency (FE) only, at least one value is adjusted which affects the primary actuating signal (E_PRIM) and/or at least one other actuating signal. The rate of rotation (N) is determined as a function of an amplitude and/or a phase of the secondary output signal (A_SEC). In addition, a rate of rotation corrective value (E6, E7), which affects the determination of the rate of rotation (N), can be adjusted as a function of the temperature (T).

摘要： The invention relates to a method and a system for monitoring a sensor arrangement comprising a vibrating gyroscope. Said vibrating gyroscope is used as a resonator and is part of at least one control circuit that excites the vibration gyroscope by feeding an excitation signal with its natural frequency. An output signal can be tapped from the vibrating gyroscope from which the excitation signal can be derived by filtering and amplification. The invention is characterized in that a first value of temperature change is calculated from the difference of the actual value of the natural frequency and a value of the natural frequency measured at a reference temperature during a comparison and stored in a memory, and the temperature coefficient of the natural frequency in relation to the measured temperature. A second value of the temperature change is calculated from the difference between the output values of a temperature sensor at the actual temperature and at a reference temperature stored in the memory and the temperature coefficient of the temperature sensor. The two calculated values are compared and an error signal is produced in case they deviate by a degree exceeding a predetermined value.
