    • A portable, self-contained, electronic radioscopic imaging system uses a pulsed X-ray source, a remote X-ray sensor, and a self-contained, display and controller unit to produce, store, and/or display digital radioscopic images of an object under investigation. An X-ray image sensor configured to spatially sense X-ray radiation pulses includes a pixel clock generator, an integrating CCD camera imager operating in a progressive scan mode providing a discrete pixel readout cycle of sensed X-ray radiation pulses, a sample and hold circuit for sampling the discrete pixel readout responsive to the pixel clock, and an analog to digital converter for digitizing each pixel as the discrete pixel readout is sampled. A digital video transmission system controller board controls the X-ray source for acquiring digitized samples from the X-ray image sensor. The digital video transmission system has a buffer memory for storing digitized pixels received from the analog to digital converter, and is further provided with a serial interface driver for transmitting the digitized pixels. An image processor receives the digitized pixels transmitted by the serial interface driver of the controller for generating a radioscopic image from the digitized pixels.
    • 便携式,独立的电子放射线成像系统使用脉冲X射线源,远程X射线传感器和独立的显示器和控制器单元来产生,存储和/或显示数字放射线图像 被调查对象 配置为空间感测X射线辐射脉冲的X射线图像传感器包括像素时钟发生器,以逐行扫描模式操作的积分CCD相机成像器,其提供感测的X射线辐射脉冲的离散像素读出周期,采样和保持 用于对响应于像素时钟的离散像素读取进行采样的电路;以及模数转换器,用于在离散像素读出被采样时对每个像素进行数字化。 数字视频传输系统控制器板控制用于从X射线图像传感器获取数字化样本的X射线源。 数字视频传输系统具有用于存储从模数转换器接收的数字化像素的缓冲存储器,还具有用于发送数字化像素的串行接口驱动器。 图像处理器接收由控制器的串行接口驱动器发送的数字化像素,用于从数字化像素生成放射线图像。

    • A portable two-part fastening device having a female section including a keyhole, a spring within the female section, and a ridge supported by the spring, an open channel in the female section contiguous with the narrow dimension of the keyhole, and means for mounting the female section to one part of the device. A male section comprises a button larger than the keyhole but having a width less than the open channel, with a flattened stud connecting said button to the other part of the two device. The button has an indentation on the outer face thereof of a geometrical configuration so as to mate with the ridge on the spring. The narrow dimension of the stud has a width less than the narrow dimension of the keyhole whereby the button and the stud may be positioned such that the button passes through the open slot and the stud passes through the narrow dimension of the keyhole with the spring exerting a biasing force against the face of the button hole so that the button and stud are maintained within the female portion.
    • 一种便携式两部分紧固装置,其具有阴部分,该阴部分包括锁眼,阴部分内的弹簧和由弹簧支撑的脊,与凹口的窄尺寸相邻的阴部分中的开放通道,以及用于安装 女性部分到设备的一部分。 阳部分包括比锁孔大的但具有小于开放通道的宽度的按钮,具有将所述按钮连接到两个装置的另一部分的扁平螺柱。 按钮在其外表面上具有几何形状的凹陷,以便与弹簧上的脊匹配。 螺柱的窄尺寸具有小于锁孔的窄尺寸的宽度,由此按钮和螺柱可以被定位成使得按钮穿过开口槽,并且螺柱穿过钥匙孔的窄尺寸,弹簧施加 偏压力抵抗按钮孔的表面,使得按钮和螺柱保持在阴部内。
