The field of electrical measurement continues to grow, with new techniques developed each year. From the basic thermocouple to cutting-edge virtual instrumentation, it is also becoming an increasingly "digital" endeavor. Books that attempt to capture the state-of-the-art in electrical measurement are quickly outdated. Recognizing the need for a text devoted to the major areas underlying modern electrical measurement, Slawomir Tumanski developed Principles of Electrical Measurement. This text builds a solid foundation in the necessary background concepts and fundamentals needed to develop and use modern electrical instruments. The author first introduces the fundamentals-including main terms and definitions, methods of estimating accuracy and uncertainty, and standards of electrical quantities-and the classical methods of measurement. He then delves into data acquisition, signal conditioning, and signal processing for both analog and digital signals. The final chapter examines computer measuring systems and virtual measurement techniques. By focusing on the aspects that are common to all types of electrical measurement, the book ensures a solid understanding that can be easily applied in practice. Whether used as an introduction to the field or as a reference to the essential concepts, Principles of Electrical Measurement provides the knowledge necessary to develop measurement solutions for any application.
This book provides a practical and accessible understanding of the fundamental principles of virtual instrumentation. It explains how to acquire, analyze and present data using LabVIEW (Laboratory Virtual Instrument Engineering Workbench) as the application development environment. The book introduces the students to the graphical system design model and its different phases of functionality such as design, prototyping and deployment. It explains the basic concepts of graphical programming and highlights the features and techniques used in LabVIEW to create Virtual Instruments (VIs). Using the technique of modular programming, the book teaches how to make a VI as a subVI. Arrays, clusters, structures and strings in LabVIEW are covered in detail. The book also includes coverage of emerging graphical system design technologies for real-world applications. In addition, extensive discussions on data acquisition, image acquisition, motion control and LabVIEW tools are presented. This book is designed for undergraduate and postgraduate students of instrumentation and control engineering, electronics and instrumentation engineering, electrical and electronics engineering, electronics and communication engineering, and computer science and engineering. It will be also useful to engineering students of other disciplines where courses in virtual instrumentation are offered. Key Features : Builds the concept of virtual instrumentation by using clear-cut programming elements. Includes a summary that outlines important learning points and skills taught in the chapter. Offers a number of solved problems to help students gain hands-on experience of problem solving. Provides several chapter-end questions and problems to assist students in reinforcing their knowledge.
For both students and engineers in R&D, this book explains machine vision in a concise, hands-on way, using the Vision Development Module of the LabView software by National Instruments. Following a short introduction to the basics of machine vision and the technical procedures of image acquisition, the book goes on to guide readers in the use of the various software functions of LabView's machine vision module. It covers typical machine vision tasks, including particle analysis, edge detection, pattern and shape matching, dimension measurements as well as optical character recognition, enabling readers to quickly and efficiently use these functions for their own machine vision applications. A discussion of the concepts involved in programming the Vision Development Module rounds off the book, while example problems and exercises are included for training purposes as well as to further explain the concept of machine vision. With its step-by-step guide and clear structure, this is an essential reference for beginners and experienced researchers alike.

Arduino boards have impressed both hackers and professional engineers. Whether you're a hobbyist or a professional, it isn't just a breadboard and a hazy idea that keeps you going. It's essential to institute a proper design, device instrumentation and, indeed, test your project thoroughly before committing to a particular prototype. Practical Arduino Engineering begins by outlining the engineering process, from the basic requirements and preliminary design to prototyping and testing. Each and every chapter exemplifies this process and demonstrates how you can profit from the implementation solid engineering principles—regardless of whether you just play in your basement or you want to publicize and sell your devices. Arduino is a brilliant prototyping platform that allows users to test and iterate design ideas. Imitation by other Arduino makers, hackers and engineers often proves your design's popularity. Practical Arduino Engineering will teach you to follow the engineering process carefully; over time, you will be able to review and improve this process, and even extend its scope. Practical Arduino Engineering is not purely theoretical. In addition, you'll learn the process of hardware engineering as applicable to Arduino projects, and the importance of the process in each and every project presented in this book. To set the stage, Practical Arduino Engineering begins by reviewing the Arduino software landscape, then shows how to set up an Arduino project for testing. Even if you already know your compiler toolchain and the basics of Arduino programming, this refresher course can help fill in the gaps and explain why your compiler may spit out certain error messages. Practical Arduino Engineering then gradually builds up the engineering process, from single devices like LCDs, potentiometers and GPS modules, to the integration of several modules into larger projects, such as a wireless temperature measurement system, and ultimately an entire robot. The engineering projects become progressively more challenging throughout the first 4 engineering chapters. Next, you'll proceed with simple steps towards the first intelligent part of a robot: the object detector. You'll find yourself teaching your robot how to avoid very hot objects or insurmountable obstacles. The basic design requirements for a complete robot and, indeed, the detailed design and prototyping for robots can be extremely tricky, which is why engineering discipline is invaluable. Practical Arduino Engineering then enters the world of domestic engineering by introducing home alarm systems—not quite as simple as they seem. A solid, robust system can only be built by following the engineering process detailed in previous chapters, and this section reinforces that process. You'll then take a step further in your Arduino engineering process: instrumentation and control, and some error messaging using GSM. Control is introduced via the Xbox controller, a very powerful piece of technology able to play a considerable role in robotics projects. Having already learned to control motion and to sense and avoid objects, you'll learn how to debug your Arduino projects of varying complexities via the hardware instrumentation software LabVIEW. To complete the journey into Practical Arduino Engineering, you'll discover how to use a special Arduino board to rely on Bluetooth Mate Silver for control of domestic and mobile Arduino projects. Using Bluetooth Mate Silver, you'll learn to implement basic engineering design with almost any Arduino project, and be able to justify, build, debug, and extend Arduino-based designs using a solid engineering approach. Please note: the print version of this title is black & white; the eBook is full color.
