Since the principle of multi-carrier code division multiple access (MC-CDMA) was simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS) has rapidly become one of the most wide spread independent research topics on the field of mobile radio communications. Therefore, the International Workshop on Multi-Carrier Spread Spectrum (MC-SS) was initiated in the year 1997. Multi-carrier and spread spectrum systems with their generic air interface and adaptive technologies are considered as potential candidates to fulfill the requirements of next generation mobile communications systems.

Micro-Electro-Mechanical Systems (MEMS) are miniature systems composed ofintegratedelectricalandmechanicalpartstosenseand/orcontrolthingsonaμmscale. The concept of MEMS is attributed to Richard Feynman’s famous talk on December 29th, 1959 [2,3]. Dr. Feynman foresaw many aspects of future MEMS development with his insight in microphysics. In particular, material properties in the μm scale are differentfrombulkpropertiesandthescalingdownofintegratedcircuits(IC)fabrication technology has been a major driving force of MEMS development.

It all started rather innocuously. I walked into Dr GT Murthy’s office one fine day, andchanged my life. “Doc” was then the General Manager, Central R&D, of a very largeelectrical company headquartered in Bombay. In his new state-of-the-art electronics center,he had hand-picked some of India’s best engineers (over a hundred already) ever assembledunder one roof. Luckily, he too was originally a Physicist, and that certainly helped me gainsome empathy. Nowadays he is in retirement, but I will always remember him as athoroughly fair, honest and facts-oriented person, who led by example. There were severalthings I absorbed from him that are very much part of my basic engineering persona today.You can certainly look upon this book as an extension of what Doc started many years agoin India … because that’s what it really is! I certainly wouldn’t be here today if I hadn’t metDoc. And in fact, several of the brash, high-flying managers I’ve met in recent years,desperately need some sort of crash course in technology and human values from Doc!

熱計量表MBUS遠傳總線接線標準1.M-BUS介紹M-Bus(是Paderborn大學的Dr.Horst Ziegler與TI公司的Deutschland GmbH和TechemGmbH共同提出的,)專門用于公共事業(yè)儀表的總線結(jié)構(gòu),稱Meter-Bus,簡稱M-Bus.M-Bus儀表總線屬于局域網(wǎng)(Local Area Net-work,簡稱LAN),是處于同一幢建筑或方圓幾公里遠地域內(nèi)的專用網(wǎng)絡(luò),被用于連接遠程監(jiān)控計算機和工作站、測量儀表等設(shè)備,以便資源共享和數(shù)據(jù)傳輸。M-Bus儀表總線具有LAN的3個基本特征:(1)范圍,(2)傳輸技術(shù),(3)拓撲結(jié)構(gòu)。LAN具有星形、環(huán)形和總線形拓撲結(jié)構(gòu)。M-Bus一般采用總線形拓撲結(jié)構(gòu)。如下圖M-Bus儀表總線可以滿足由電池供電或遠程供電的計量儀表的特殊要求。當計量儀表收到數(shù)據(jù)發(fā)送請求時,將當前測量的數(shù)據(jù)傳送到主站,(主站可以是手持單元、計算機或其它終端),主站定期地讀取某幢建筑中安裝的計量儀表的數(shù)據(jù)。一般而言,掛接在儀表總線上的計量儀表的數(shù)目可達數(shù)百個,數(shù)據(jù)傳輸距離達數(shù)千米。在總線上傳送的數(shù)據(jù)具有高度的完整性和快速性。通信線選擇通常選擇2芯1.0mm2的RVVP多股銅線線,電源及通信線復用。網(wǎng)絡(luò)最遠距離不宜超過1000m,最大負載數(shù)量不宜超過256戶。安裝注意事項
