Three-axis Seismometer
Wide coverage and accurate detection of nuclear detonations are critical to prevent proliferation. Such applications require extremely high sensitivities on the order of approximately 0.5 ng/sqrt(Hz) on all three axes of acceleration, as well as robustness and cost effectiveness. Current sensors are too large or insensitive to be widely distributed in a sensor network. Agiltron, an innovator of...
متن کاملSystem Error Compensation Methodology Based on a Neural Network for a Micromachined Inertial Measurement Unit
Errors compensation of micromachined-inertial-measurement-units (MIMU) is essential in practical applications. This paper presents a new compensation method using a neural-network-based identification for MIMU, which capably solves the universal problems of cross-coupling, misalignment, eccentricity, and other deterministic errors existing in a three-dimensional integrated system. Using a neura...
متن کاملLow-Noise MEMS Vibration Sensor for Geophysical Applications
The need exists for high-sensitivity, low-noise vibration sensors for various applications, such as geophysical data collection, tracking vehicles, intrusion detectors, and underwater pressure gradient detection. In general, these sensors differ from classical accelerometers in that they require no direct current response, but must have a very low noise floor over a required bandwidth. Theory i...

The need exists for high-sensitivity, low-noise vibration sensors for various applications such as geophysical data collection, vehicle tracking, intrusion detection, and underwater pressure gradient detection. In general, these sensors differ from classical accelerometers in that they require no dc response, but must have a very low noise floor over a required bandwidth. Theory indicates a cap...
متن کاملA Novel Angular Acceleration Sensor Based on the Electromagnetic Induction Principle and Investigation of Its Calibration Tests
An angular acceleration sensor can be used for the dynamic analysis of human and joint motions. In this paper, an angular acceleration sensor with novel structure based on the principle of electromagnetic induction is designed. The method involves the construction of a constant magnetic field by the excitation windings of sensor, and the cup-shaped rotor that cut the magnetic field. The output ...
