"This book is designed to provide engineers with a better understanding of heat treatment and its effects on gear quality and performance, especially as these considerations are critical to ensuring that the gears perform satisfactorily under anticipated service conditions. Increased demand for gears to transmit more power through smaller, lighter, quieter, and more reliable packages that must operate over a wide range of service conditions has made the design and manufacture of gears much more complex. Gears manufactured from certain steels are found to meet these demands, and become especially effective when heat treated and finish machined for high geometric accuracy. However, distortion of the gear after heat treatment offers the engineer a challenging opportunity not only in ensuring a high quality product but also in controlling manufacturing costs. Heat treat distortion of gears is discussed in detail for the major heat treat process, and a case history of each successful gear heat treat process is included. Contents: Introduction to Gear Heat Treatment Properties of Iron Heat Treatment of Gears Through-Hardening Process Carburizing and Hardening Nitriding Modern Nitriding Processes Carbonitriding Induction Hardening Selection of Heat Treat Process for Optimum Gear Design."

"This book covers ALL aspects of projected capacitive touch sensors including basic principles, the physics of PCAP, capacitance measurements, touch sensor materials and construction, electrical noise, software drivers, and testing. It is targeted at working engineers who are implementing touch into their products as well as anyone else with an interest in how touch screens work.- Offers readers the first book on the use of projected capacitive (PCAP) touch technology for touch screens;- Explains not only how PCAP touch works, but also addresses the implementation details an engineer needs when incorporating PCAP into their product;- Includes explanations of different cover lens materials, cover lens coatings, software drivers, touch testing, and many other areas of general knowledge that would be useful to a design engineer."

"Bronchial asthma : a guide for practical understanding and treatment, sixth edition, is a fully updated version of a widely respected classic on the diagnosis and management of asthma. Discussing the disorder in all relevant patient groups, including a variety of patient subpopulations, this invaluable title continues to emphasize the definition, medications, and practical use of asthma treatment plans. Importantly, this comprehensive reference also discusses the common side effects found in the full range of medications used for asthma treatment. "
