一种简单的心率测量系统设计，能显示并进行上下限报警(A simple heart rate measurement system design, and upper and lower alarm)

本程序是虚拟示波器，可以显示多条曲线波形，调节幅值和时间(Oscilloscope can display multiple curve )

说明：  器件参数：ATMega16/32，内部8.0000Mhz 实现功能：红外解码(IR Decoding source code source code integrity, and can be used directly.)

钢轨磨耗测量系统，属非接触式测量，实现了钢轨磨耗的快速，精确测量(Rail wear measurement system is a non-contact measurement, the rail wear realize fast, accurate measurement)

针对H264 JM中encode_a_picture函数进行讲解的PPT，希望对大家的学习有所帮助(For H264 JM in encode_a_picture function to explain the PPT, we hope to be helpful to learn)

绿灯亮时，准许车辆通行，黄灯闪烁时，已越过停止线的车辆可以继续通行；没有通过的应该减速慢行到停车线前停止并等待，红灯亮时，禁止车辆通行。给行人看的叫人行横道灯，通常指由红、绿（绿为蓝绿）二种颜色灯组成用来指挥交通通行的信号灯，红灯停，绿灯行。(When the green light is on, the vehicle is allowed to pass. When the yellow light is flashing, the vehicles that have crossed the stop line can continue to pass.You should slow down to stop and wait at the stop line. No traffic is allowed when the red light is on.Pedestrian crossing lights for pedestrians, usually denoted by red, green (green, blue, green), two color lamps used to direct traffic signals, stop at red lights and green.)

数据转换为正弦图，最终输出的正弦图为平均正弦图。(Data into sine figure, final output sine the graph is the average sinogram.)

说明：  使用vb与衡河9140示波器连接，并控制采集一列脉冲数据，对数据进行分析，计算脉宽、积分面积、平均电压，并将波形通过picture控件显示在界面上(Using vb oscilloscope connected with the value for r. 9140, and a pulse control and data acquisition data, analyze data, calculate pulse width, integration area, average voltage, and waveform display in the interface through the picture controls on)
