The design of the seam tracking sensor is the key work in the realization of the welding automatization. A novel touch photoelectric sensor for seam tracking was designed on the base of getting over the shortcoming of non-touch seam tracking sensor and using the principle of the photovoltaic translation. The idler pulley can touch the seam closely, then the sensor can realize the auto-tracking by the oriented function of the groove. If the offset of the idler pulley location appear, the sensor can change the offset to the voltage using the cell of the photovoltaic translation and the cell of signal processing.

焊缝跟踪传感器的设计是焊接自动化实现过程的重要环节，在此克服非接触式焊接跟踪传感器易受干扰的缺点，利用光电转化的原理，设计了一种新颖的接触式光电焊缝跟踪传感器，该传感器利用特制导轮与坡口紧密接触，依靠坡口的机械导向作用实现焊缝自动跟踪，当导轮位置发生偏移，利用光电转换单元以及信号处理单元，可将偏移位移转化为模拟电压量。

In order to measure the passive network's conduction automatically, a network conduction instrumentation based on FPGA technology was designed and implemented according to the design principle of Virtual Instrument. System adopted FPGA technology building a digital flat-top to imitatively produce the high quality sine signal. Under the control of C8051MCU, measurement, calculation and display of the port network's conduction were automatic implementation. Furthermore, the system has the function of frequency step measurement.

The ostium of frontal sinus Positions should be divided into two type by the interaction of basal lamella of bulla and cribriform roof. TypeⅠ: The ostium of frontal sinus is located in lateral sinus, flows through superiorsemilunar hiatus to middle nasal meatus. It is about 20%. TypeⅡ: The ostium of frontal sinus is located in ethmoid infundibulum, frontal recess and its cell, flows through interior semilunar hiatus to middle nasal meatus. It is about 80%. Among them there are about 62.5% in ethmoid infundibulum, about 37.5% in frontal recess.

额窦鼻口的位置可根据筛泡基板与筛顶连接的情况划分为两种类型：Ⅰ型额窦的鼻口开口于侧窦，经上半月裂流入中鼻道，约占20%；Ⅱ型开口于筛漏斗、额隐窝及其气房，经下半月裂流入中鼻道，约占80%，其中开口于筛漏斗约为62.5%；开口位于额隐窝约为37.5%。

If you wish to compress a particular track of a multitrack recording or one channel of a live performance, connect the 166XL INPUT to the audio source's output jack while the 166XL OUTPUT can be directly connected to a line input jack or the 166XL's INPUT and OUTPUT can be wired to an Insert point. In the latter case, the signals will most likely be unbalanced.

如果你希望压缩一个特殊的多音轨录音的轨迹或一个实时演奏的声道，可连接166XL的输入端口到音源的输出端口，同时166XL输出直接连接到一个线性输入接口，或166XL的输入输出连接到一个插口点，在后来的事例中，信号大多数像非平衡式信号。
