    • This device is related to the domain of fully automatic machines for oil extraction. An axle transmission and soft belt suspension system is used in the device. A decelerator connects an electric motor and a driving hub, so that the transmission belt can be driven. When the driven hub and the bridle are connected, the sucker rod will be connected so that the oil-well pump can start working. There are several other units, an absolute value coder that can measure the driven hub's angle of rotation, a augmenter coder that can measure the rotational speed of the electric motor and an oil gauge. In the device, a oil production process controller processes collects signals and then the device controls the machine, the beam and the pump system automatically. It has the advantages of saving energy, high efficiency for oil extraction and long operational life span.
    • 该设备涉及全自动抽油机。 装置中使用轴传动和软带悬挂系统。 减速器连接电动机和驱动轮毂,从而驱动传动带。 当从动轮毂和马达被连接时,抽油杆将被连接,以便油井泵可以开始工作。 还有其他几个单元,可以测量从动轮毂的旋转角度的绝对值编码器,可以测量电动机和油位计的转速的增强器编码器。 在设备中,油生产过程控制器处理收集信号,然后设备自动控制机器,梁和泵系统。 具有节约能源,提油效率高,使用寿命长的优点。

    • A metric representing the sum of variances for pixel blocks of a region of an image are used to identify the presence a video feature of the image, and a transcoding is performed responsive to identifying the presence of the video feature. The identified video feature can include, but is not limited to, a scene change, the presence of a black border region or a caption region, or the complexity of the image. The transcoding operation can include, but is not limited to, coding the image as an Intra-frame, omitting the content corresponding to the black border region or the caption region from the transcoded image or allocating a relatively lower bit budget for the black border region or a relatively higher bit budget to the caption region during transcoding of the image, or setting the bit budget for rate control during transcoding.
    • 用于表示图像区域的像素块的方差之和的度量用于识别图像的视频特征的存在,并且响应于识别视频特征的存在来执行代码转换。 识别的视频特征可以包括但不限于场景改变,黑色边界区域或字幕区域的存在,或图像的复杂性。 代码转换操作可以包括但不限于将图像编码为帧内帧,从代码转换的图像中省略与黑色边界区域或字幕区域相对应的内容,或者为黑色边框区域分配相对较低的比特预算 或在图像代码转换期间到字幕区域的相对较高的比特预算,或者在转码期间设置用于速率控制的比特预算。
