Free Robots ebooks Dielectric Phenomena Antennas for Portable Devices

Dielectric Phenomena in Solids

This book deals mainly with the phenomena resulting from the responses of the solid dielectric materials to external applied forces such as electromagnetic fields, mechanical stress, and temperature. The materials considered are mainly nonmetallic and nonmagnetic materials, which are generally not considered as dielectric materials. There is no clear demarcation between dielectrics and semiconductors. We can say that the major difference lies in their conductivity and that the dominant charge carriers in semiconductors are generated by the thermal excitation in the bulk, while those in dielectric materials come from sources other than the thermal excitation, including carrier injection from the electrical contacts, optical excitations. The trend of electronics has been directed to the use for some solid-state devices of some dielectric materials, such as ceramics, which have good insulating properties as well as some special features such as spontaneous polarization. Therefore, a chapter dealing with
ferroelctric, piezoelectric, pyroelectric, and electro-optic phenomena, as well as a chapter dealing with electrets, are also included in this book.

Antennas for Portable Devices
This edited book represents another significant achievement, bringing together contributions from key players in the topical areas of antenna designs for RFID tags, laptop computers, wearable devices, UWB systems, and microwave thermal therapies. Major issues and design considerations are discussed and explained in the various chapters.For aesthetic reasons, all these systems require small antennas that can be embedded into the mobile units. Furthermore, for minimally invasive microwave thermal therapies, small and thin antennas are much preferred.

Creating Cool Mindstorms NXT Robots
This book is divided into two parts. With the first, I want to break away from the same boring wheeled robots—there are too many of them around. We’re used to vehicles; we want to move on legs! So, this part is devoted to walking robots—bipeds in particular. In Chapter 1,
I tried to summarize the state of the art for LEGO bipedal walkers. Subsequent Chapters 2, 4, and 5 present three biped robots in order of complexity. Chapter 3 is the only real theoretical
chapter, where you learn the finite state machine software technique to give your robot personality and autonomous behaviors. In Chapter 6, the NXT Turtle is described. This is a quadruped robot, featuring a funny autonomous behavior.

System on Package: Miniaturization of the Entire System

This book introduces the SOP concept for miniaturizing the entire system. It argues for the benefits of system miniaturization which include lower cost, higher electrical performance and better thermo-mechanical reliability, than the current approach of discrete component packaging. It then systematically describes each of the SOP technologies starting with SOP design, and integration of digital, RF and optical functions in the system package. The next set of chapters describe the SOP materials and process fabrication technologies, assembly, test and reliability by using a variety of interconnection technologies. The last chapter, Biosensor SOP, introduces the unique application of SOP concept for a variety of biomedical applications.
