Errors in fabricating and installing reflective prisms

Journal of Optical Technology, 2011
This paper analyzes how errors of fabrication and deployment affect the position of the baseline (the optical axis) when reflective prisms are being assembled. An expression is obtained for the law of refraction in matrix form, making it possible to use a simple and obvious derivation to obtain the decoplanarity invariant.

Experimental analysis of accelerometer installation error

2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, 2010
When accelerometer is installed, errors would be produced, which will greatly degrade the measurement accuracy, so to the tracking precision while being applied in the compound control. We make the experimental analysis for the accelerometer installation, in which the accelerometer is installed parallel to the azimuth and 30° degree away the azimuth ...

Effects of child restraint system features on installation errors

Applied Ergonomics, 2014
This study examined how child restraint system (CRS) features contribute to CRS installation errors. Sixteen convertible CRS, selected to include a wide range of features, were used in volunteer testing with 32 subjects. Subjects were recruited based on their education level (high or low) and experience with installing CRS (none or experienced).

Analysis and calibration on installation errors of accelerometer in GFSINS

2009 Chinese Control and Decision Conference, 2009
Aim at the precision limitation for calculating angular velocity because of installation errors of accelerometer in the gyro free strapdown inertial navigation system (GFSINS), a calibration method of installation error parameters is put forward. Based on a six-accelerometer configuration scheme, the calculating method of angular velocity and linear ...

Disturbance characteristics analysis of CMG due to imbalances and installation errors

IEEE Transactions on Aerospace and Electronic Systems, 2014
The control moment gyroscope (CMG) is used as the actuator of attitude control for modern satellites. Because of static and dynamic rotor imbalances and installation errors, it becomes one of the main vibration sources on a satellite. To provide a quiet environment for optical payloads, CMG disturbance characteristics due to imbalances and installation

The error analysis of the localization result caused by the installation errors of a seabed array of magnetometers

2016 IEEE Chinese Guidance, Navigation and Control Conference (CGNCC), 2016
It has a great military significance to detect the magnetic target by magnetic gradiometer system. The positional accuracy of magnetic target will be affected by the installation error of magnetometer in the magnetic gradiometer system. The relationship between the localization results and the installation error is analysed in this paper.

Analyzing the installation angle error of a SAW torque sensor

Measurement Science and Technology, 2014
When a torque is applied to a shaft, normal strain oriented at ±45° direction to the shaft axis is at its maximum, which requires two one-port SAW resonators to be bonded to the shaft at ±45° to the shaft axis. In order to make the SAW torque sensitivity high enough, the installation angle error of two SAW resonators must be confined within ±5 ...

Error estimate of a fiber optic displacement transducer installation

Measurement Techniques, 1990
Existing contactless photoelectric systems for dynamic displacement measurements are awkward, not very convenient, and primarily are utilized in stationary laboratory installations. These disadvantages are absent in fiber-optic transducers (FOT) that are among a known class of devices, fiber-optic sensors of physical quantities that convert the ...

How to discover circuit errors in meter installations

Ninth International Conference on Metering and Tariffs for Energy Supply, 1999
Yearly financial losses to energy suppliers caused by connection errors in meter installations are not to be neglected. There are many possibilities to make incorrect connections during installation. Many times, installation faults are rarely discovered at the time of billing and sometimes not recognised for many years.
