    • A pipe crawler tractor may comprise a half tractor assembly having a first base drive wheel, a second base drive wheel, and a top drive wheel. The drive wheels are mounted in spaced-apart relation so that the top drive wheel is positioned between the first and second base drive wheels. The mounting arrangement is also such that the first and second base drive wheels contact the inside surface of the pipe at respective first and second positions and so that the top drive wheel contacts the inside surface of the pipe at a third position, the third position being substantially diametrically opposed to the first and second positions. A control system connected to the half tractor assembly controls the rotation of the first base wheel, the second base wheel, and the top drive wheel to move the half tractor assembly within the pipe.

    • A telepresence system includes a camera pair remotely controlled by a control module affixed to an operator. The camera pair provides for three dimensional viewing and the control module, affixed to the operator, affords hands-free operation of the camera pair. In one embodiment, the control module is affixed to the head of the operator and an initial position is established. A triangulating device is provided to track the head movement of the operator relative to the initial position. A processor module receives input from the triangulating device to determine where the operator has moved relative to the initial position and moves the camera pair in response thereto. The movement of the camera pair is predetermined by a software map having a plurality of operation zones. Each zone therein corresponds to unique camera movement parameters such as speed of movement. Speed parameters include constant speed, or increasing or decreasing. Other parameters include pan, tilt, slide, raise or lowering of the cameras. Other user interface devices are provided to improve the three dimensional control capabilities of an operator in a local operating environment. Such other devices include a pair of visual display glasses, a microphone and a remote actuator. The pair of visual display glasses are provided to facilitate three dimensional viewing, hence depth perception. The microphone affords hands-free camera movement by utilizing voice commands. The actuator allows the operator to remotely control various robotic mechanisms in the remote operating environment.
    • 远程呈现系统包括由附接到操作者的控制模块远程控制的摄像机对。 相机对提供三维观看,并且固定到操作者的控制模块提供相机对的免提操作。 在一个实施例中,控制模块固定在操作者的头部上并建立起始位置。 提供三角测量装置以跟踪操作者相对于初始位置的头部运动。 处理器模块从三角测量装置接收输入以确定操作者相对于初始位置移动的位置,并响应于此移动相机对。 相机对的移动由具有多个操作区域的软件映射预先确定。 其中每个区域对应于独特的相机移动参数,例如移动速度。 速度参数包括恒速或增减。 其他参数包括平移,倾斜,滑动,升高或降低相机。 提供其他用户界面设备以改善操作者在本地操作环境中的三维控制能力。 这样的其他设备包括一对视觉显示眼镜,麦克风和远程致动器。 提供一对视觉显示眼镜以便于三维观看,因此深度感知。 麦克风通过使用语音命令提供免提相机移动。 执行器允许操作者远程控制远程操作环境中的各种机器人机构。

    • A flow meter and temperature measuring device comprising a tube with a body centered therein for restricting flow and a sleeve at the upper end of the tube to carry several channels formed longitudinally in the sleeve to the appropriate axial location where they penetrate the tube to allow pressure measurements and temperature measurements with thermocouples. The high pressure measurement is made using a channel penetrating the tube away from the body and the low pressure measurement is made at a location at the widest part of the body. An end plug seals the end of the device and holes at its upper end allow fluid to pass from the interior of the tube into a plenum. The channels are made by cutting grooves in the sleeve, the grooves widened at the surface of the sleeve and then a strip of sleeve material is welded to the grooves closing the channels. Preferably the sleeve is packed with powdered graphite before cutting the grooves and welding the strips.
