This is a practical book, to be sure, but it is also a book about hope and posi- tive change. I am quite sincere. The delivery of electricity is deeply rooted in the principle of universal access; when clean, reliable energy is available it contributes to poverty alleviation, improved social conditions, and enhanced economic development. In the developed world, we know this to be true. The digital fabric of our lives is a testimony to the importance of energy security. Across the globe, we have seen the vital contributions that electrification has brought to the development of economies and an enhanced quality of life. Nonetheless, this supreme engineering achievement has languished, and we are deeply challenged.

It was the publisher’s idea that I write RFID in the Supply Chain: A Guide to Selection and Implementation . Not only am I editor of Enterprise Inte- gration System , Second Edition Handbook and author of The Complete Book of Middleware , I also had some innovative business process and project management ideas on improving the effectiveness of integrating enterprise systems with information on product traceability, the scope of which has been widened by the RFID technology mandates.

The purpose of this book is to present detailed fundamental information on a global positioning system (GPS) receiver. Although GPS receivers are popu- larly used in every-day life, their operation principles cannot be easily found in one book. Most other types of receivers process the input signals to obtain the necessary information easily, such as in amplitude modulation (AM) and frequency modulation (FM) radios. In a GPS receiver the signal is processed to obtain the required information, which in turn is used to calculate the user position. Therefore, at least two areas of discipline, receiver technology and navigation scheme, are employed in a GPS receiver. This book covers both areas.

I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95! Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and think of all the possibilities built into that piece of hardware. I am amazed by what has happened to everything from toasters to car engines. Who-da-thunk-it 40 years ago?

I am presenting this novel book on advances and trends in power electronics and motor drives to the professional community with the expectation that it will be given the same wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer- sity professors, and even graduate students that my other books in this area have. Unlike the traditional books available in the area of power electronics, this book has a unique presentation format that makes it convenient for group presentations that use Microsoft’s PowerPoint software. In fact, a disk is included that has a PowerPoint file on it that is ready for presentation with the core figures. Presentations can also be organized using just selected portions of the book

DS1302 是 DALLAS 公司推出的涓流充电时钟芯用 内含有一个实时时钟/日历和31字节静态RAM,通过简单的串行接口与单片机进行通信。实时时钟/日历电路提供秒、分、时、日、日期、月、年的信息,每月的天数和闰年的天数可自动调整,时钟操作可通过AM/PM指示决定采用24或12 小时格式。DS1302 与单片机之间能简单地采用同步串行的方式进行通信,仅需用到三个口线: (DRES(复位),(2)I/O(数据线), (B)SCLK(事行时钟)。时钟/RAM的读/写数据以会个字节或多达31个字节的字符组方式通信。DS1302 工作时功耗很低,保持数据和时钟信息时功率小于1mW。 DS1302是由DS1202 改进而来,增加了以下的特性:双电源管脚用于主电源和备份电源供应,Vcc!为可编程涓流充电电源,附加七个字节存储器。它广泛应用于电话、传真、便携式仪器以及电池供电的仪器仪表等产品领域。
