This book was released on 2023-12-15 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unified approach for the two versions of Coriolis vibratory gyroscopes: Micro-Electro-Mechanical System (MEMS) and non-MEMS. It describes a new, differential mode of operation, analyzing the new triple mode gyro—rate, rate-integrating, and differential. The latter provides the gyro with an increased versatility by providing the maximum possible accuracy under changeable motion parameters and environmental conditions. The book also presents computer simulation, experiments, and test results on the rejection of external disturbances, and considers the fabrication processes of MEMS, metallic and quartz resonators. It will interest researchers, scientists, engineers, and students specializing in the field of inertial sensors, as well as engineers of digital control systems, and inertial sensors test-engineers. It can also be used as a reference book when designing vibratory gyros.
Download or read book Imperfections in a Cylindrical Vibratory Gyroscope written by Mercy Nduku Ngungu and published by . This book was released on 2014 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discusses that In 1890 Bryan observed that a rotating vibrating structure tends to have a vibrating pattern that rotates at a rate proportional to the rate of rotation. This is otherwise known as the Bryan effect. Based on this theory a formula, the so-called "Bryan’s factor" was derived to quantify this shift in angular velocity. This study will utilise the linear theory developed in Joubert, Shatalov and Fay (2009, [9]) with an assumption that the rotation rate is constant and much smaller than the lowest eigenvalue of the vibrating system. This theory is used in conjunction with the math mathematical model formulated to determine how to include mass-imperfections and pre-stress using a non-linear theory of elasticity, as well as how to include anisotropic (viscous) damping into an equation of motion using Rayleigh dissipation (see Joubert et al. (2011, [10])). Hence, the problem statement of this research study is to investigate the influence of mass-imperfections and linear anisotropic (viscous) damping on the angle of vibrating pattern and the phase shift of the vibrating pattern of a slowly rotating thin cylindrical body.

Available in PDF, EPUB and Kindle. Book excerpt: Combining different perspectives from materials science, engineering, and computer science, this reference provides a unified view of the various aspects necessary for the successful realization of intelligent systems. The editors and authors are from academia and research institutions with close ties to industry, and are thus able to offer first-hand information here. They adopt a unique, three-tiered approach such that readers can gain basic, intermediate, and advanced topical knowledge. The technology section of the book is divided into chapters covering the basics of sensor integration in materials, the challenges associated with this approach, data processing, evaluation, and validation, as well as methods for achieving an autonomous energy supply. The applications part then goes on to showcase typical scenarios where material-integrated intelligent systems are already in use, such as for structural health monitoring and smart textiles.

Download or read book Advanced Microsystems for Automotive Applications 2003 written by Jürgen Valldorf and published by Springer Science & Business Media. This book was released on 2007-12-22 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microsystems are an important factor that contribute to an automobile model's success. To meet the customer's desire for safety, convenience and vehicle economy, and to satisfy environmental standards, microsystems play a critical factor. Microsystems applications (MST) have already resulted in improved performance and better value for money. But the advances implemented reveal only the beginning of a revolution in the vehicle sector, which aims at a complete transition from the mechanically driven automobile system to a mechanically based but ICT-driven system. The selected contributions from AMAA 2003 treat safety (both preventive and protective), powertrain (online measurement and control of engine and transmission subsystems), comfort and HMI (systems to enhance the comfort of passengers and human machine interface issues), and networked Vehicle (all aspects of intra car systems and ambient communication networks).

This book was released on 2005-03-17 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1995 the annual international forum on Advanced Microsystems for Automotive Applications (AMAA) has been held in Berlin. The event offers a unique opportunity for microsystems component developers, system suppliers and car manufacturers to show and to discuss competing technological approaches of microsystems based solutions in vehicles. The book accompanying the event has demonstrated to be an efficient instrument for the diffusion of new concepts and technology results. The present volume including the papers of the AMAA 2005 gives an overview on the state-of-the-art and outlines imminent and mid-term R&D perspectives. The 2005 publication reflects – as in the past – the current state of discussions within industry. More than the previous publications, the AMAA 2005 "goes back" to the technological requirements and indispensable developments for fulfilling the market needs. The large part of contributions dealing with sensors as well as "sensor technologies and data fusion" is exemplary for this tendency. In this context a paradigm shift can be stated. In the past the development focused predominantly on the detection and processing of single parameters originating from single sensors. Today, the challenge increasingly consists in getting information of complex situations with a series of variables from different sensors and in evaluating this information. Smart integrated devices using the information deriving from the various sensor sources will be able to describe and assess a traffic situation or behaviour much faster and more reliable than a human being might be able to do.
