1 1. 1 Introduction The (signal processing and storage) capacity ofthe human brain enables us to become powerful autonomous beings, but only if our brains operate in conjunction with (at least some of) our senses and muscles. Using these organs, we can interact with our environment, learn to adapt, and improve important aspects of our life. Similarly, the signal processing capabilities of modern electronics (computers) could be combined with electronic sensors and actuators to enable interaction with, and adaptation to, the (non-electrical) environment. This willlead to smarter and more powerful automated tools and machines. To facilitate and stimulate such a development, easy-to-use low-cost sensors are needed. The combination of electronic interface functions and a sensor in an integrated smart sensor, that provides a standard, digital, and bus-compatible output, would simplify the connection of sensors to standard electronic signal processors (microcontrollers, computers, etc. ). Currently, the calibration procedure, required for standardization of the sensor output signal level, contributes largely to the production costs of accurate sensors. To enable automation of the calibration procedure, and hence reduce the sensor fabrication costs, a digital calibrationjunction should be included in the smart sensor. INTEGRATED SMART SENSORS: Design and Calibration Introduction 1. 2 Sensors and actuators In industry many processes are electronically controlled. As depicted in Fig.

In this book, author Nate Furuta, former chair and CEO of Toyota Boshoku America Inc., shares the story of his decades of experience directly leading the establishment of Toyota cultures outside Japan. Furuta was the first Toyota employee on the ground at New United Motor Manufacturing Inc. (NUMMI), Toyota's joint venture in California with General Motors, where he directly led the establishment of the most revolutionary labor-management agreement in the history of the US auto industry. In addition, Furuta was the first Toyota employee on the ground in Georgetown Kentucky at Toyota's first full-scale, wholly owned manufacturing operation outside Japan, where he led (working directly with President Fujio Cho) the establishment of Toyota's general management systems and culture there. This book tells the stories of establishing successful operations in those two iconic organizations as well as others. Furuta reveals details, both stories and process descriptions that only he can tell. He takes you along as he and others lead Toyota's intense globalization from the early 1980s to recent days. He introduces you to the critical leaders in Toyota's history, such as Taiichi Ohno and Fujio Cho as well as Kenzo Tamai, the head of the company's HRM function in the 1980s. This book is not about human-resource management (HRM) policies and procedures. It provides a deep dive into the way senior leaders embody deep awareness of HRM matters, developing and executing company strategy while at the same time developing organizational capability. The role of senior leaders isn't just a matter of directing the company to achieve objectives; it is a matter of building the capability to achieve those objectives, consistently, and further developing capability as it executes. Key to this is to develop the awareness, attitude, capability, and practice of identifying problems as progress is made toward achieving objectives, which is, in fact, attained through steadily eliminating each problem as it arises. This becomes a self-reinforcing loop of the organization, tapping in to the essence of solving problems while simultaneously developing ever better problem-solving skills and better problem solvers. This loop propels an organization toward meeting its purpose while developing capability for capability development. Essentially, this book reveals Toyota's general management systems from the firsthand experience of a Toyota Japanese senior manager and describes, with stories and process examples, the attitude, behaviors, and systems needed to successfully establish and lead in a true Lean business environment.

This book weaves together spirituality and a systemic version of emotional intelligence that incorporates Kurt Lewin's social science and other sources. Emotional intelligence calls on us to be fully present "to the moment." It calls on us to be appreciative of ourselves and our relationships. Likewise, a calm and compassionate presence is almost universally recognized as a spiritual way of being. In other words, the overwhelming majority of the world's spiritual sources call on us to be emotionally intelligent and that link is explored with unique clarity in this simple yet powerful text. We are all reactive at times. Becoming more objective and less attached allows us to feel our feelings without being a prisoner to acting on them in habitual ways. From a more detached perspective, feelings are neither good nor bad, but simply clues as to how we are perceiving our environment, especially our social environment. This is especially important in terms of our relationships at work. Our perceptions about what people intend trigger our emotional reactions. Think about the difference when you perceive critical feedback as a sincere attempt to help or when you perceive it as an attack of some sort. Perception evokes different emotional responses. Objectivity about our own perception is even more important than objectivity about emotion, because the former usually precedes the later. Paradoxically, being detached allows one to appreciate and experience one's emotions more fully. Recognizing emotion as part of your inner guidance system instead of as something dangerous that must be controlled or denied is freeing. The less emotion runs you, the more you can accept feeling what you feel. Emotion is a form of physical energy. Fighting your own feelings takes energy. Allowing the ebb and flow of emotion is essential to physical and emotional health and to accepting ourselves as we are.

Ignition is a book of dispatches from the frontlines of communication strategy. Matthew L. Moseley draws on his eclectic life experiences to investigate the link between success and effective communication. Whether he's choreographing a fine dining experience at the top restaurant in America, using rock stars to register voters, helping a national chain save its reputation after a gaffe goes viral, or serving as media liaison at the epic ash-blast send-off for author Hunter S. Thompson, Moseley identifies the principles that guide communication strategies toward their goals. In extensive interviews with a wide variety of experts, including authors, fighter pilots, business leaders, politicians, and astrophysicists, Moseley tests these principles, teases out new, provocative ideas, and anticipates how forming stronger connections will help us address today's greatest challenges. Though it tackles serious subjects, offers an illuminating perspective on the evolution of human discourse, and shares important insights on interpersonal relations, Ignition is also a good, fun read. A broad range of colorful anecdotes gives this book of philosophical wisdom and practical advice the zest of a juicy memoir.

This book provides a comprehensive overview of potential opportunities and the business value position related to implementing physics-based real-time simulation to production. The objective of real-time simulation is to provide value for all three dimensions of sustainability: economic, social, and environmental. By reviewing actual industrial cases and presenting relevant academic research, the book examines the topic from four interrelated viewpoints: the industrial need for sustainable production, the development of game-like virtual environments, capturing customer value and enhancing the user experience, and finally, establishing business value. It offers a framework that will enable a rethink and shift in mindset to appreciate how real-time simulation can change the way products are manufactured and services are produced. This book will appeal to researchers and scholars in areas as diverse as strategic management, manufacturing and operations management, marketing, industrial economics, and product lifecycle management.

This is a self-study guide for facilitators of rapid process improvement workshops that helps anyone who feels like they aren't truly gaining the full results of improvement initiatives and kaizen events. They know they can do better, but don't know how. The author, an experienced facilitator in government and nonprofits, speaks to the facilitator through coaching notes and actual workshop documents and techniques so the reader can fully understand how greater results are achieved. This guide takes the reader through a step-by-step path of a newly created workshop agenda. The author has parsed the workshop path into more manageable parts, easier for both the facilitator and the team. These parts split the improvement work into two sections: "removing the unnecessary" and "smoothing out the flow." "Smoothing out the flow" is divided further into: When the work is coming in When the product/person is going through the process How the work is performed In addition, the author includes newly created tools and training content. For example, a data-gathering table points the facilitator to what data need to be collected when. Training for the team includes making sure they understand the structure of a process as well as to instruct them and define how a Lean process actually functions. This distinction is important because all improvements are not necessarily Lean improvements. Several bodies of knowledge are incorporated into this guide--not only Lean and Six Sigma, but internal auditing, organizational development, and statistics. Essentially, this guide includes tips, nuances, and original tools that are missing from the traditional training of facilitators of kaizen events. It provides enough information for the facilitator to think in a creative way.

Now back in print, this life of George Eastman is the first biography since 1930 of the man who transformed the world of photography. In this revealing and informative work, Brayer shows us how such key innovations as roll film and the light, hand-held camera helped the Eastman Kodak Company dominate the world market. More importantly, Brayer draws a vivid portrait of the man behind the money. Eastman worked hard at staying out of the limelight and even insisted that his donations be kept anonymous, prompting the Boston Globe to call him "America's most modest and least-known millionaire." Despite his retirement in 1925, Eastman showed little sign of slowing down. Making money had been interesting, but putting money to work became more so. In the 1920s he designed a special camera for use in orthodontia and established elaborate dental clinics for needy children around the world. He oversaw the building of the Eastman theatre and the Eastman School of Music. His contributions built a new campus for the Massachusetts Institute of Technology and a new medical school for the University of Rochester. Finally, he became the largest contributor to the education of African Americans during the 1920s and the Tuskegee Institute's most important benefactor. Elizabeth Brayer lives in Rochester, NY. For the past 18 years she has served on both the George Eastman Legacy and the Landscape committees at the George Eastman House, International Museum of Photography and Film. She writes about the history of central and Western New York State. George Eastman: A Biography was nominated for a Pulitzer Prize in 1996.

Maintaining good business leadership in a world of rapidly changing expectations levied by customers, investors, society, governments and employees is a challenge. These stakeholders are increasingly making choices about if or how they support businesses - through the purchase of their products and services, shareholdings and financing, regulatory approvals, and even experiences working for them - based on not just what a business does, but how it does it. We are seeing shifts in stakeholder sentiments that manifest in a greater expectation that businesses work with society in addressing society's contemporary concerns. This greater good that businesses bring is rewarded by a greater brand awareness, connection and loyalty, which in turn provides businesses with an underlying strategic advantage over the competition with its customers, investors and other stakeholders. But this greater good cannot be faked with PR and bought media; in an increasingly connected world populated by an increasingly savvy millennial stakeholder base, authentic leadership and its ability to effect cultural shifts in the DNA of businesses is essential. Failure to do so will likely result in shorter and less successful tenures of Board members and C-suite leaders as this business trend spreads. This book looks at how the emerging generation of leaders must change paradigms and transform their employees to do more than just operate a business. It examines how to effect culture shifts that are necessary to innovate businesses so that they simultaneously meet market needs while meeting stakeholder expectations on concerns as varied as ethical business conduct, labor practices, climate change, responsible use of diminishing natural resources and contribution to socio-economic challenges in their market catchments. These are perspectives and skills that are still glossed over, by academic and professional institutions, as they develop the leaders of the future. Essentially, this book: * Articulates the strategic business case for doing good in a good business; the why, and where this trajectory is leading * Provides strategies to lead authentically on the array of issues that provide key stakeholders - customers, investors, governments and employees - with a greater reason to engage with and build loyalty to the business * Provides strategies to energize and spark innovation among his/her employees in an organization on these issues so that transformative power is harnessed.

Process consultation, invented by Edgar Schein, is both a skill and an organization development change effort. As a skill, process consultation means the ability to observe and provide feedback about small group dynamics to a work group about how well group members interact and how to improve that interaction. Just as facilitators devote their time to (in one word) asking, process consultants devote their time to (in one word) watching-at an expert level. As a change effort, process consultation is a concerted effort to help members of a group work together more effectively. For that reason, the word "process" in this context should be interpreted to mean "interpersonal interaction in small groups." Historically, process consultation has focused attention on face-to-face groups and their group dynamics. But times are changing. More work is done online or in blended (online and onsite) groups than face-to-face alone. A 2017 survey of over 25,000 workers in 12 countries revealed that 62% of global workers are now working flexibly-with some residential work and some virtual work. The same survey found that workers believe that flexible work arrangements make them more productive and that 48% of survey respondents reported that their virtual interactions include representatives of other cultures. It is true that, for workers who can discipline themselves and manage distractions at home, virtual work can be more productive when commuting time is eliminated and workplace distractions are minimized. Virtual work has the advantage of reducing the need for childcare, slashing work wardrobe costs, and cutting unproductive, stressful commuting time. Despite how modes of working together have changed over the years-ranging from face-to-face to some degree of virtual (video conference, audio conference, print-only collaboration, and many blended combinations)-and the growing need for finding ways to help people work together more effectively, there has been no practical guideline of process consultation in a virtual or mixed work setting since Schein's process consultation initially focused on group dynamics in face-to-face settings. Therefore, this book aims to provide practical approaches to process consultation, helping group members discover more effective ways of working together in blended virtual/residential and cross-cultural settings. Essentially, this book provides a practical, how-to guide for virtual coaching, using step-by-step procedural approaches, cases, and helpful platforms/technologies and tools. It also provides information about how to use technology to support the process of improving virtual or mixed group relationship.
