查询词典 signal

Nowdays,the infrared camera in our country can export video signal and digital image signal. The video signal can display on the screen through the general grab card, but the digital one can not be inputted into computer without special image grab card. In this paper, an infrared image grab card and the correlative program driver are designed based on the analysis of the universe technology.

Results: Typical DNT was located in cortical or subcortical white matter, with cystic or semiliquid structures. On MR images appeared as lesions with inhomogeneous signal intensities, consistent MR feature in all cases were the presence of one or multiple areas of moderately or markedly reduced T1-signal and markedly or moderately increased T2-signal, with moderate enhancement.

结果：典型的DNT位于皮层或主要位于皮层区，肿瘤以囊性成分为主、病灶在T1WI为低信号，T1WI为高信号，其ADC值增高，FLAIR序列上病灶边缘和分隔为高信号改变，增强扫描病灶实质结节或分隔可见轻度强化。

At the same time, using combination of gear and photoelectric switch for the sensors, the signal conditioning box of National Instruments Corporation and data collecting card as the main devices, the signal collecting of torsional vibration was completed. In addition, a software of the fault monitoring and analysis was developed with Visual C++. The signal real time collecting of torsional vibration and processing were realized.

同时，以齿盘和光电开关组合为传感器，NI的信号调理箱、数据采集卡等为主要器件实现了扭振信号采集；并采用Visual C++编程开发了故障监测与分析软件，实现了对扭振信号的实时采集和处理。

Because elevator's movement is according to the floor and the sedan theater box calling signal, the traveling schedule signal carries on the control, but the floor and the sedan theater box's call is stochastic, therefore, the systems control uses the random logic control, namely, in realizes in elevator's basic control request foundation by the order logical control, According to the stochastic input signal, as well as elevator's corresponding condition, at the right moment controls elevator's movement.

由于电梯的运行是根据楼层和轿厢的呼叫信号、行程信号进行控制，而楼层和轿厢的呼叫是随机的，因此，系统控制采用随机逻辑控制，即在以顺序逻辑控制实现电梯的基本控制要求的基础上，根据随机的输入信号，以及电梯的相应状态，适时地控制电梯的运行。
