Visual-inertial self-calibration on informative motion segments

, 2017
Environmental conditions and external effects, such as shocks, have a significant impact on the calibration parameters of visual-inertial sensor systems. Thus long-term operation of these systems cannot fully rely on factory calibration.

Novel Calibration Strategy for Kalman Filter‐Based Measurement Fusion Operation to Enhance Aging Monitoring

Quality and Reliability Engineering International, Volume 41, Issue 6, Page 2290-2305, October 2025.
ABSTRACT This study introduces a novel calibration strategy for the linear Kalman filter (LKF) fusion application in condition monitoring, specifically utilizing accelerated aging data. Unlike the existing literature that often focuses on complex nonlinear Kalman filter variants, this research delves into the calibration of LKF.

Noise and thermal stability of vibrating micro-gyrometers preamplifiers [PDF]

, 2007
The preamplifier is a critical component of gyrometer's electronics. Indeed the resolution of the sensor is limited by its signal to noise ratio, and the gyrometer's thermal stability is limited by its gain drift.

Enhanced Vertical Sidewall Quality for Functional AlN Films in 3D Piezo MEMS Applications

Advanced Electronic Materials, Volume 11, Issue 15, September 18, 2025.
This work examines cryogenic deep reactive ion etching (cryo‐DRIE) and hydrogen annealing to prepare vertical silicon sidewalls suitable for aluminium nitride (AlN) film growth. Achieving smooth and crystalline AlN on these surfaces is essential for microelectromechanical systems (MEMS) applications requiring three dimensional (3D) sensing and ...

MEMS: The Sensory Nervous System for Embodied AI Robots

SmartBot, Volume 1, Issue 3, September 2025.
Embodied AI represents a shift of intelligence from virtual to physical realms, calling for efficient and multimodal perceptual capabilities. This review illustrates how Micro‐Electro‐Mechanical Systems (MEMS) offer miniaturized, low‐power sensors such as those for ranging, inertia, touch, sound and smell, which serve as robotic “sensory organs”.

Construction and Demonstration of a Seaplane‐Type UAV‐Based High‐Precision GNSS‐A Seafloor Crustal Deformation Observation System

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract The Global Navigation Satellite System—Acoustic combination (GNSS‐A) is used to observe seafloor crustal deformation by determining the global position of the seafloor with GNSS positioning and acoustic ranging between a sea surface platform and a transponder station located on the seafloor. However, GNSS‐A observations are currently conducted
