Intensive development of digital technologies coincided in time with the beginning of the new era in telecommunications. It made possible to formalize many proce- dures of data exchange and to atomize some operations which made providing of serviceandmakeworkofmanytelecommunicationworkersmucheasier. Somenew telecommunication technologies were born out of the necessity for use of specific configurations of network elements and networks, as well as for a possibility of providing maximum characteristics of efficiency combined with high requirements to the stability of operation, the overcoming of different catastrophic situations and deadlockconditions,such as failuresand ”pending”of the networkandthe like. The thresholdbetweeninformationsystems andtelecommunicationsystems has become practically invisible. It resulted in such a new term as ”infocommunication”

The next avatar of the Internet will revolutionize our world. In time, it will provide us a universal remote control, enabling us to monitor and control physical objects located anywhere on the planet, using a smart phone. It will make the universe around us programmable, allowing us to script the behav- ior of physical objects with electronic commands. This book is about such an emerging new version of the Internet.

Radio frequency identification (RFID) is gaining in popularity, especially as we find ourselves in this communications age and headed towards a ubiquitous computing world. Automatic identification systems become an important aspect not just in today’s technology but also as part of our daily life. We need RFID in our cars, transportation systems, access points, and even simple transactions; we also acknowledge the need for RFID in our logistics systems, healthcare, and tracking and locating applications.

目的:自主研制一款超聲手術(shù)刀電源控制系統(tǒng),以減少能量的消耗,維持手術(shù)刀的正常溫度。方法:對超聲換能器在諧振附近的等效電路建立模型,并設(shè)計(jì)基于數(shù)字信號處理(DSP)的超聲手術(shù)刀的硬件控制系統(tǒng)。結(jié)果:經(jīng)對電源控制系統(tǒng)的電路和工作性能測試,生成的電流和電壓的有效值等參數(shù),能夠及時(shí)調(diào)整電源的頻率,并達(dá)到預(yù)期的功能指標(biāo),使超聲手術(shù)刀工作在諧振狀態(tài)。結(jié)論:以DSP為核心設(shè)計(jì)的超聲手術(shù)刀電源控制系統(tǒng),測試指標(biāo)均能夠達(dá)到預(yù)期的要求,能夠使系統(tǒng)在諧振狀態(tài)下工作。Objective: To independently develop a power control system of ultrasonic scalpel so as to reduce the energy consumption and maintain the normal temperature of ultrasonic scalpel. Methods: In this paper, the model of equivalent circuit of ultrasonic transducer nearby syntony was built up, and the hardware control system of ultrasonic scalpel based on digital signal processing(DSP) was designed. Results: Through testing the circuit and work performance of power control system, the series of parameters such as effective value and so on which were produced by this system could adjust frequency of power source in time and attain anticipative functional indicator, and it took the ultrasonic scalpel to work in syntonic situation. Conclusion: The tested indicators of power control system of ultrasonic scalpel based on the kernel design of DSP can attain anticipative requirement, and can take this system to work in syntonic situation.

DSP音頻處理示例The benefits of real-time analysis provided by DSP/BIOS are often required in programs that were engineered without it. When the program is not built from the ground up using the DSP/BIOS kernel and real-time analysis features, the lack of familiarity prevents engineers from reaping the benefits of this very powerful tool set, especially in the final stage of development when real-time analysis is needed most. This application note provides an example of the necessary steps required to utilize DSP/BIOS features in order to bring these solutions to bear in an existing application.

Ever wanted to just type tail -f error_log on Windows?Envious of your Unix friends who can track changes to a file, in real time, as they happen? Well, now with the Objektiv Tail for Win32, you ll be happily monitoring your log files like you ve never done before. What s even better, you can track several files all at the same time with the patented "Multiple Document Interface"TM technology, with each file having its own, fabulous window.
