High speed current sensing system for welding

High Speed Full Swing Current Mode BiCMOS Logical Operators

In this paper the design of a new high-speed current mode BiCMOS logic circuits isproposed. By altering the threshold detector circuit of the conventional current mode logic circuitsand applying the multiple value logic (MVL) approach the number of transistors in basic logicoperators are significantly reduced and hence a reduction of chip area and power dissipation as wellas an increase in spee...

A high-speed low-latency portable visual sensing system

The Mechanism of Undercut Formation and High Speed Welding Technology

Automatic Welding System Using Speed Controllable Autonomous Mobile Robot∗

A prototype of autonomous mobile robot with two vision sensors for automatic welding of steel plates was constructed. The robot can move straight, steer and turn around the robot center by controlling the driving speed of the two wheels respectively. At the tip of the movable arm, two CCD cameras are fixed. A local camera observes the welding line near the welding torch and another wide camera ...
