Abstract: This application note describes the essential workings of an electrocardiogram (ECG). It discussesfactors that disrupt the ECG signals and make reliable, highly-accurate electrical characterization difficult. Theindustry-standard solution for ECG electrical characterization, which uses an analog Front-End and ADCcombination, is explained. The article then introduces the MAX11040 simultaneous-sampling, sigma-deltaADC as a compelling, highly integrated solution that eliminates the need for the AFE, and saves both spaceand cost for the application.

Abstract: High-speed and low-speed data converters serve critical functions in modern broadband mobile radios. This application note outlines how todetermine high-speed data converter performance requirements in baseband sampling radio architectures. Also, system partition strategies andadvantages are outlined when considering a high-speed analog Front-End (AFE) solution.

在研究传统家用燃气报警器的基础上，以ZigBee协议为平台，构建mesh网状网络实现网络化的智能语音报警系统。由于传感器本身的温度和实际环境温度的影响，传感器标定后采用软件补偿方法。为了减少系统费用，前端节点采用半功能节点设备，路由器和协调器采用全功能节点设备，构建mesh网络所形成的家庭内部报警系统，通过通用的电话接口连接到外部的公用电话网络，启动语音模块进行报警。实验结果表明，在2.4 GHz频率下传输，有墙等障碍物的情况下，节点的传输距离大约为35 m，能够满足家庭需要，且系统工作稳定，但在功耗方面仍需进一步改善。 Abstract: On the basis of studying traditional household gas alarm system, this paper proposed the platform for the ZigBee protocol，and constructed mesh network to achieve network-based intelligent voice alarm system. Because of the sensor temperature and the actual environment temperature, this system design used software compensation after calibrating sensor. In order to reduce system cost, semi-functional node devices were used as Front-End node, however, full-function devices were used as routers and coordinator，constructed alarm system within the family by building mesh network，connected to the external public telephone network through the common telephone interface, started the voice alarm module. The results indicate that nodes transmit about 35m in the distance in case of walls and other obstacles by 2.4GHz frequency transmission, this is able to meet family needs and work steadily, but still needs further improvement in power consumption.

The power of programmability gives industrial automation designers a highly efficient， cost-effective alternative to traditional motor control units （MCUs）。 The parallel-processing power， fast computational speeds， and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control （FOC）。 Additionally， Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing （DSP） that can tackle compute-intensive functions such as PID Controller， Clark/Park transforms， and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving， proven， motor-control reference designs. The kit also shortens the process of developing custom control capabilities， with integrated peripheral functions （Ethernet， PowerLink， and PCI® Express）， a motor-control FPGA mezzanine card （FMC） with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators， and prototyping support for evaluating alternative Front-End circuitry.

This manual describes omniidl, the omniORB IDL compiler. It is intended for developers who wish to write their own IDL compiler back-ends, or to modify existing ones. It also documents the design of the compiler Front-End for those poor souls who have to track the IDL specification.

Student status management system is development two aspects that typical information management system, IMS( MIS), its development includes primarily the background database creates with support and the front end applies the procedure.Creates to rise to the former request the consistency of data is strong with the integrity, the library that the safeness of data like.But request the latter very much to apply the procedure function complete, easy usage etc. characteristics.

Using the UnderC Tokenizer Class It s often necessary to parse complex text files, where standard i/o is too clumsy. C programmers fall back on strtok(), but this can be tricky to use properly. Besides, you are still responsible for keeping strtok() fed with new input, and I don t like the schlepp. Tokenizer is a text-parsing input stream, modelled after the (undocumented) VCL TParser class, and based on the UnderC tokenizing preprocessor Front-End.
