查询词典 signal device

An important feature of the device is that the phase shift is nearly constant with signal level.

该设备的一个重要特点是，相移几乎与信号水平不变。

A device, such as a photoelectric cell, that receives and responds to a signal or stimulus.

传感器接收信号或刺激并反应的器件，例如光电池

The small hole of the optical inducer of the traditional second-generation optical mouse used for receiving the images faces downwards, and corresponding light sources (including photoelectric diode and laser diode), optic lens and photosensitive holes are arranged at the lower part of the mouse; therefore, moving the whole mouse is a relatively convenient method for generating displacement of the mouse pointer; oppositely, the small hole of the optical inducer used for receiving the images faces upwards and corresponding light sources, optical lens and photosensitive holes (7) are arranged at the upper part of the mouse; matters on the upper surface of the photosensitive hole (7) can be moved so as to lead the mouse pointer to generate the displacement, while the moving signal transmitted by a photoelectric conversion device must be reset so as to comply with the integrated mouse of the invention.

传统的第二代光电鼠标的光学感应器接收图象的小孔是向下的，对应的光源(包括光电二极管，激光二极管)、光学透镜和感光孔都是在鼠标下部分，这样要想鼠标指针产生位移较方便的方法就是移动整个鼠标；相反，光学感应器接受图象的小孔向上，对应的光源、光学透镜和感光孔(7)在鼠标上部分，要使鼠标指针产生位移就只需移动附在感光孔(7)上面的物质，但必须重新设置光电转换装置传出的移动信号，以符合本发明。

The internal device such as noise and interference, such as optical pyroelectric sensor signal and transient.

内部由于器件等的噪声和干扰，如光热释感应器的信号瞬变等。

ABSTRACT: The comprehensive survey present resistance, the electric capacity and the inductance reflectoscope reflector, are generally and the special function signal generating device ties up in the same place, mostly price expensive, the volume is big, is not suitable uses in needing to move the survey the situation and the field work.

综观现在的电阻，电容和电感测试仪，一般是和专门的函数信号发生器捆绑在一起，大多价格昂贵，体积较大，不适宜用于需要移动测量的场合和野外作业。

It can detect the index of human balance function with scatheless convenient safe means. The system circuit of the device contains a RC low-pass filter, which is able to eliminate interferential thin lines and thus improve the function of magnifying signal.

该系统的电路中还引用了RC低通滤波器有效的消除细纹干扰，改善放大信号的功能，完全可以达到无创、便捷、安全地完成人体平衡功能指数的检测。

Scrambler - A device that electronically alters a program signal so that it can be seen only by persons, typically paid subscribers, with appropriate decoding, or "descrambler" devices.

扰频器 -此电子设备可以改变一个节目的信号，只有在正确的解码或安装正确的装置时，才能被特定人群收看，特别是付费订户。

Disclosed are information display device and method for image display instrument which analysing the received weather information, date information and area code in the auxiliary information, extracting the weather information of relative area, corresponding the weather information to the preset weather index and life index, and displaying the result together with the image signal which is received in a preset period on the sereen.

本发明公开了一种图像显示仪器的信息显示装置及方法，分析被接收的附加信息中的天气信息，日期信息及地区代码等，提取用户收看的相应地区的地区天气信息，将相应的天气信息与已设定的天气指数及生活指数等对应起来，将其与按已设定的设定时间为周期接收的图像信号一同显示在屏幕上。
