應急系統(Emergency System, ES)主要是針對自然災害,安全事故，危險物泄露，街頭騷亂,恐怖活動等突發事件發生后所采取的一系列應急措施和行動而建立的系統，主要目的是在最短的時間內最大限度地減輕災害所造成的損失。

Alkaline batteries are convenient because they’re easy tofi nd and relatively inexpensive, making them the powersource of choice for portable instruments and devicesused for outdoor recreation. Their long shelf life alsomakes them an excellent choice for Emergency equipmentthat may see infrequent use but must be ready to go on amoment’s notice. It is important that the DC/DC convertersin portable devices operate over the widest possiblebattery voltage range to extend battery run time, and thussave the user from frequent battery replacement.

針對煤礦井下調度及緊急救援系統的需求，以DTMF編解碼模塊為核心，設計了具有自動撥號功能的新型電話系統。該系統利用MT8880對DTMF信號的編解碼功能實現一鍵撥號和遠程設置，通過檢測振鈴和忙音信號，完成自動摘機和掛機過程，配合AGC等外圍電路達到話音清晰流暢的效果。 Abstract: To meet the demand for mine scheduling and Emergency rescue system， with using DTMF signal codec as the core， a new telephone system was designed with automatic dialing function. In the system， the DTMF signal encoding and decoding function of MT8880 was used to achieve one-touch dialing and remote setting. The circuit detects the ringing and busy signal， and then completes automatic off-hook and hangup. With AGC(Automatic Gain Control) and other peripheral circuits， the voice was regulated to a clear and smooth effect.

In the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic communication for Emergency operations, disaster relief efforts, and military networks. Such network scenarios cannot rely on centralized and organized connectivity, and can be conceived as applications of mobile ad hoc networks. A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the

Mobile radio networks have risen in prominence over the last few years, primarily by the rise in popularity of cellular phones. It is important to recognise however that mobile radio technology fulfils a far wider range of applications that meet the demands of the modern world. These include the networks that allow police and Emergency services to serve the public, military networks for operations and humanitarian support, and the mobile technol- ogies that are vital to the safety of aircraft.

With the rapid development of electric vehicles (EVs) as well as the promotion and application of vehicle-to-grid (V2G) technologies, EVs charging loads, as flexible loads, have the potential to participate in the grid services, including peak shaving and valley filling, frequency regulation (FR), Emergency power, energy market participation, and so on. Therefore, great attention has been paid to EVs and V2G. Focusing on the interactions between EVs and power system, this book aims to bring readers with basic knowledge of electrical engineering promptly to the frontier of the EVs’ influence on power system and environment. This book may serve as a reference for scientists, electrical engineers, and postgraduate students majoring in electrical engineering or other related fields.

In this new edition of the book, only minor changes were made to the original nine chapters but three new chapters treat topics of increasing interest to GPS users and equipment developers. One topic, improving the GPS receiver sensi- tivity may extend their operations into buildings, which is becoming important for Emergency rescue and urban warfare.
