Übersetzung für "Drift error" in Deutsch

Sensor errors such as scale factor errors, drift or zero error, misalignment and cross coupling are compensated for.

So, a possibly existing temperature or long-term drift error can be balanced in a simple manner in the optical arrangement.

To compensate for a drift error, it appears advantageous to provide a special reference remission surface at the end of the evaluatable reaction zone of the testing tube, and to derive a signal for drift correction from the image of this reference remission surface at the end of the sensor array.

This necessitates a measurement over a period of time during which the drift error may even assume impermissibly-large dimensions.

Errors in the parametrisation can be caused in the electronics by external influences, aging, drift, operator error or similar.

The method can be used for operating a force-measuring device, such as a balance. An exemplary method serves to correct drift phenomena that are caused by extraneous influence factors and/or by device properties and behaviors of an electronic force-measuring device, particularly a balance with a measuring transducer that produces a measuring signal representing the magnitude of an applied load and delivers the signal by way of an analog/digital converter to a processor-based digital signal-processing unit which has the capability to compensate for drift deviations and which for this purpose has access to drift parameters that are stored in a memory unit and provide the basis for calculating a time-dependent correction value and for correcting the drift error of the measuring signal.

Two friction sensors minimize the effect of the thermal drift error on the friction measurement in a range from room temperature to 1000 °C.

In order to reduce the problem of the continuously increasing error (“drift”), use is made of so-called Zero Velocity Updates (ZUPTs) so that, in the phases when the foot is resting on the ground, the EKF can be set to zero velocity (so-called pseudo measurement).

If the geographically coded image taken with the vehicle-mounted camera matches the geographically corresponding photorealistic image data, it can be concluded that the in-vehicle navigation system GPS is not affected by a drift error.

A circle 12 represents the reading of the in-vehicle navigation system for the position of the vehicle, wherein the reading is in this case inaccurate due to a drift error.

Inertia-based position determination systems are also subject to position errors (resulting particularly from the drift error in combination with, for example, the above-mentioned errors in GNSS systems).

In order to determine if the in-vehicle navigation system is affected by a drift error, after it has been corroborated in step 104 that the geographically coded snapshot images of the surroundings of the vehicle do not match the stored photorealistic imagery for the location given by the in-vehicle navigation system, it should be determined whether the vehicle is still on the last matched road or on a previously matched road, as shown in step 116 .

The printing quality is increased, since the register error is always recorded and corrected, not only during a calibration process prior to the printing process, thus identifying a register drift error that occurs with longer printing machine operating times.

Even when the bridge is amplitude-balanced, a phase shift occurs which results, in case of phase-sensitive demodulation, in a “zero-drift” error, affected resolution and temperature instability of the output signal.

With a corresponding selection of the components, a drift error of the circuit of 1 per mil can be achieved over a temperature range of 50° K. The temperature coefficient of resistor and capacitor should not be greater than 15 ppM/° K. (parts per million/° Kelvin).

If the geographically coded images generated with the cameras in step 102 do not match the photorealistic image data available for the same location as indicated by step 104, the following options are possible: First, the in-vehicle navigation system is affected by a drift error, i.e. the GPS provides inaccurate data and therefore the system compares imagery of two different locations.

Absorption of ions and contamination of the electrodes, which may cause drift errors.

In this manner, eventual errors of temperature or long term drift errors present in the optical configuration can be simply corrected.

Then, except for drift errors and errors due to the determination of the phase voltage during excitation, no further errors occur.

Since only one electronic measuring channel is used, any measurement errors, such as those due to differing non-linear characteristic curves and thermal or wear related drifting, which errors are typically prevalent in known measurement devices, are largely eliminated.

Since in the indicated example of 3 out of 8 gyros therefore a total of 56 individual measurement systems which can be evaluated for detection of the angular orientation in space can be described, the accuracy of the desired measurement result with respect to drift and other errors can be significantly increased by averaging and other statistical considerations.

Errors in the parametrisation or in the power calculation can be caused in the electronics by external influences, aging, drift, errors by the operating personnel or the like.

The conductivity measuring device according to the present invention excludes polarization effects, it prevents electrolysis processes in the electrolyte, and it also excludes or markedly reduces drift errors caused by an absorption of ions or by contamination in the area of the measuring elements.

By averaging the measurement results of the individual diffractograms across such an azimuth tilt series, the influence of fixed object-specific and object drift-specific systematic errors on the end result is reduced.

The particular advantage of the method is that in practice it is much easier to measure accelerations with small drift errors than velocities or distances.

The difficulty to be overcome is that scale errors and drift errors of the gyroscope are not independent statistical variables.

In preferred exemplary embodiments, the microcontrollers 52 a, 52 b are further designed to detect drift errors in the switching elements 70, 72 on the basis of the current measurement.

The particular advantage of the acceleration-based method is that in practice it is much easier to measure accelerations with small drift errors than velocities or distances.
