Book excerpt: In recent years, inertial sensors have been extensively studied and thoroughly researched to enhance their performance and robustness, overcoming great challenges for better innovations. The complicated fabrication processes of inertial sensors' manufacturing may potentially cause defects and lead to the reduction in their capabilities for detection of signals while environmental factors such as temperature can pose other obstacles and prevent the devices from obtaining the desired strength or stability. Among the many technologies that currently develop micromachined gyroscopes, MEMS (Microelectromechanical Systems) have been one of the fastest growing technologies used for gyroscope manufacturing due to their low-cost. However, one of the greatest challenges of the MEMS technology for micromachined gyroscopes is that it does not meet the requirements for inertial guidance systems. In this work, an approach is proposed to improve the robustness of a Coupled Inertial Navigation Sensor (CINS) System, which consists of a ring of vibratory gyroscopes coupled along their driving axes, bi-directionally, uni-directionary, and directly. While the sum response of synchronized states gains a larger output than an individual one, the purpose of the coupling in the drive-mode is to enhance the sensitivity and minimize the negative effects of the drift rate in a CINS device. Intensive numerical simulations are performed to investigate the behavior of this high dimensional system and its response to changes in parameters, mainly the number of gyroscopes, Coriolis force, and coupling strength. Bifurcation diagrams outlining the response of the system are obtained numerically with the aid of the continuation software AUTO 2000 and XPP. Individual behaviors, including synchronization, are further analyzed using analytical methods based on perturbation theory. The Lyapunov-Schmidt reduction is applied to determine the stability properties of the synchronized solution, which emerges through a pitchfork bifurcation that can be either supercritical or subcritical, depending on the coefficients of the nonlinear terms in the governing equations of motion. Abstract group theory is also used to predict the different patterns of motion for different ring sizes. The study of stochastic noise, assumed to be Gaussian band-limited, is explored extensively to investigate the benefits of the coupling systems over the un-coupled ones. Results show that coupling can reduce phase drift and even lead to a new concept of a drive-free gyroscope system.

This book was released on 2011 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inertial navigation systems (INS) have been studied extensively to increase their performance and enhance robustness. One critical component of the INS is the gyroscope, which is used for detecting orientation. These gyroscopes are subject to material imperfections and manufacturing defects potentially reducing their ability to detect signals and reduce phase drift. One common type of vibratory gyroscope is manufactured based on MEMS (Micro-electromechanical Systems) technology, which yields small gyroscopes at lower costs. However, with low cost gyroscopes comes a quality trade-off, specifically for inertial guidance systems. For this reason, this work explores the idea of improving the performance of vibratory gyroscopes by combining the input-output response of an ensemble of gyroscopes coupled in a ring fashion. More specifically, bidirectional coupling in both axes is investigated. Numerical simulations and analytical work show that this coupling causes the sum of the response in the synchronized state to have a larger output than an individual gyroscope. This reduces the negative effects of phase drift and positively influences the sensitivity. Numerical and analytical bifurcation diagrams also reveal regions of synchronization for given coupling strength and input rotation parameters. To demonstrate robustness this work focuses on two types of noise, variation in mass and contamination of the target signal. When subjected to this noise, improvement in phase drift is seen when the coupled gyroscopes systems are numerically compared to uncoupled systems.

Download or read book Wearable Robots written by José L. Pons and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wearable robot is a mechatronic system that is designed around the shape and function of the human body, with segments and joints corresponding to those of the person it is externally coupled with. Teleoperation and power amplification were the first applications, but after recent technological advances the range of application fields has widened. Increasing recognition from the scientific community means that this technology is now employed in telemanipulation, man-amplification, neuromotor control research and rehabilitation, and to assist with impaired human motor control. Logical in structure and original in its global orientation, this volume gives a full overview of wearable robotics, providing the reader with a complete understanding of the key applications and technologies suitable for its development. The main topics are demonstrated through two detailed case studies; one on a lower limb active orthosis for a human leg, and one on a wearable robot that suppresses upper limb tremor. These examples highlight the difficulties and potentialities in this area of technology, illustrating how design decisions should be made based on these. As well as discussing the cognitive interaction between human and robot, this comprehensive text also covers: the mechanics of the wearable robot and it’s biomechanical interaction with the user, including state-of-the-art technologies that enable sensory and motor interaction between human (biological) and wearable artificial (mechatronic) systems; the basis for bioinspiration and biomimetism, general rules for the development of biologically-inspired designs, and how these could serve recursively as biological models to explain biological systems; the study on the development of networks for wearable robotics. Wearable Robotics: Biomechatronic Exoskeletons will appeal to lecturers, senior undergraduate students, postgraduates and other researchers of medical, electrical and bio engineering who are interested in the area of assistive robotics. Active system developers in this sector of the engineering industry will also find it an informative and welcome resource.

Book excerpt: Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Book Synopsis Handbook of Modern Sensors by : Jacob Fraden
Download or read book Handbook of Modern Sensors written by Jacob Fraden and published by Springer Science & Business Media. This book was released on 2006-04-29 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives.
