LemonSMS is a component developed in Java that provides a turnkey solution for application developers to incorporate into their Java applications the functionality of Sending and processing of incoming SMS messages. LemonSMS acts as a middleware between a Java application and a GSM Modem or Data enabled phone. Because LemonSMS only provides an interface to the added SMS functionality, your application still handles access to data and business logic tier. With the easy-to-use LemonSMS API, developers can easily utilize SMS functionalities provided by LemonSMS.

These two classes show an extremely simple example of java.net socket programming. They implement the Unix daytime protocol, an extremely simple protocol that consists entirely of the server Sending its current local time and date to the client as an ASCII string. The server, to keep it very simple, does not use multiple threads. This code requires JDK 1.1 or later, but can easily be adapted to JDK 1.0.

as a message came into prominence with the publication in 1948 of an influential paper by Claude Shannon, "A Mathematical Theory of Communication." This paper provides the foundations of information theory and endows the word information not only with a technical meaning but also a measure. If the Sending device is equally likely to send any one of a set of N messages, then the preferred measure of "the information produced when one message is chosen from the set" is the base two logarithm of N (This measure is called self-information). In this paper, Shannon cont

SharpPcap c#抓包實(shí)現(xiàn)時(shí)時(shí)獲取網(wǎng)卡信息 SharpPcap tutorial: a step by step guide to using SharpPcap The text of this tutorial is taken directly from WinPcap's official tutorial but is modified to show the C# use of the SharpPcap library. All examples can be downloaded together with SharpPcap source code from SharpPcap 's homepage. The WinPcap library must be installed before attempting to run any of these examples, so please download and install the latest version from WinPcap's download page. SharpPcap was written and tested using .NET v1.1 and Windows 2000/XP. I have no idea about other .NET and Windows versions. If you do try it, please report your results. The following topics are covered in this tutorial: Obtaining the device list Obtaining advanced information about installed devices Opening an adapter and capturing packets Capturing packets without the event handler Filtering the traffic Interpreting the packets Handling offline dump files Sending Packets Gathering Statistics on the network traffic 1.

Communication protocols – for short protocols – form the basis for the opera- tion of computer networks and telecommunication systems. They are behavior conventions which describe how communication systems interact with each other in computer networks. Protocols define the temporal order of the interactions and the formats of the data units exchanged. Communication protocols comprise a wide range of different functions and mechanisms, such as the Sending and receiv- ing of data units, their coding/decoding, error control mechanisms, timer control, flow control, and many others.

CAN總線是汽車上應(yīng)用最廣泛的車載網(wǎng)絡(luò)總線,具有實(shí)時(shí)性強(qiáng)、可靠性高、成本低等優(yōu)點(diǎn)。鑒于此,介紹了一種利用飛思卡爾系列單片機(jī)MC9S12XS128作為控制器,利用其內(nèi)部的MSCAN模塊、CAN收發(fā)器TJA1040等外圍元件進(jìn)行CAN總線通信節(jié)點(diǎn)設(shè)計(jì)。該設(shè)計(jì)能夠?qū)崿F(xiàn)CAN總線數(shù)據(jù)的發(fā)送與接收,可應(yīng)用于汽車及其他各種CAN總線通信系統(tǒng)。CAN bus is the most widely used on-board network bus in automobiles. It has the advantages of realtime, high reliability and low cost. In view of this,this paper introduces the design of CAN bus communication node by using Freescale MC9S12XS128 as controller,using its internal MSCAN module,CAN transceiver TJA1040 and other peripheral components. This design can realize the Sending and receiving of CAN bus data,and can be used in automobile and other CAN bus communication systems.

基于TMS320F28035芯片為控制核心的空間矢量異步電機(jī)變頻器 我們設(shè)計(jì)的異步電機(jī)變頻調(diào)速器以TMS320F28035芯片為控制核心,通過輸出三相PWM波控制智能功率模塊IPM驅(qū)動(dòng)三相異步電機(jī)。我們使用空間矢量SVPWM算法,并對其進(jìn)行了優(yōu)化。采用檢測反電勢的方法省去了昂貴的光電編碼器,大大節(jié)省了成本。同時(shí)開創(chuàng)性的研發(fā)了自動(dòng)根據(jù)運(yùn)行環(huán)境調(diào)節(jié)的自適應(yīng)變頻算法,使我們的變頻調(diào)速器可以在電網(wǎng)條件惡劣的鄉(xiāng)村山區(qū)工作,由此該變頻器已被一家民用水泵生產(chǎn)企業(yè)預(yù)訂。關(guān)鍵字 變頻器 TMS320f28035 IPM SVPWM In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by Sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVPWM (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.
