Recent advancements in nanotechnology (NT) materials and growth of micro/ nanotechnology have opened the door for potential applications of microelectro- mechanical systems (MEMS)- and NT-based sensors and devices. Such sensors and devices are best suited for communications, medical diagnosis, commercial, military, aerospace, and satellite applications. This book comes at a time when the future and well-being of Western industrial nations in the twenty-first century’s global eco- nomy increasingly depend on the quality and depth of the technological innovations they can commercialize at a rapid pace.

HIS IS THE THIRD —and most likely the last—book in the series on information technology for energy managers and web based energy infor- mation and control systems. This book concentrates on web based enterprise energy and building automation systems, and serves as a capstone volume in this series. The thrust here is that the highest level functions of a building and facility automation system are provided by a web based EIS/ECS system that provides energy management, maintenance management, overall facility operational management, and ties in with the enterprise resource management system for the entire facility or the group of facilities being managed. If there were ever to be a fourth volume in this series, it would follow the logical progression of the first three volumes, and would probably be titled Web Based Enterprise Resource Management Systems.

This book is based on a Ph.D. research that has been conducted at the Delft University of Technology in the Netherlands in collaboration with Dutch Electricity & Gas Distribution Network Operator, Stedin. This book was written as a result of wider interest that was shown by different industry groups on this topic after its public defence. This inspired the author to modify and publish a practical version of the research for a greater international audience. Therefore, the content of this book is intended for a double audience, on the one hand for those interested in the organisational and management aspects of maintenance.

便攜式B型超聲診斷儀具有無創傷、簡便易行、相對價廉等優勢，在臨床中越來越得到廣泛的應用。它將超聲波技術、微電子技術、計算機技術、機械設計與制造及生物醫學工程等技術融合在一起。開展該課題的研究對提高臨床診斷能力和促進我國醫療事業的發展具有重要的意義。 便攜式B型超聲診斷儀由人機交互系統、探頭、成像系統、顯示系統構成。其基本工作過程是：首先人機交互系統接收到用戶通過鍵盤或鼠標發出的命令，然后成像系統根據命令控制探頭發射超聲波，并對回波信號處理、合成圖像，最后通過顯示系統完成圖像的顯示。 成像系統作為便攜式B型超聲診斷儀的核心對圖像質量有決定性影響，但以前研制的便攜式B型超聲診斷儀的成像系統在三個方面存在不足：第一、采用的是單片機控制步進電機，控制精度不高，導致成像系統采樣不精確；第二、采用的數字掃描變換算法太粗糙，影響超聲圖像的分辨率；第三、它的CPU多采用的是51系列單片機，測量速度太慢，同時也不便于系統升級和擴展。 針對以上不足，提出了基于FPGA的B型超聲成像系統解決方案，采用Altera公司的EP2C5Q208C8芯片實現了步進電機步距角的細分，使電機旋轉更勻速，提高了采樣精度；提出并采用DSTI-ULA算法（Uniform Ladder Algorithm based on Double Sample and Trilinear Interotation）在FPGA內實現數字掃描變換，提高了圖像分辨率；人機交互系統采用S3C2410-AL作為CPU，改善了測量速度和系統的擴展性。 通過對系統硬件電路的設計、制作，軟件的編寫、調試，結果表明，本文所設計的便攜式B型超聲成像系統圖像分辨率高、測量速度快、體積小、操作方便。本文所設計的便攜式B型超聲診斷儀可在野外作業和搶險（諸如地震、抗洪）中發揮作用，同時也可在鄉村診所中完成對相關疾病的診斷工作。
