  • Fast response capacitive gauging system featuring steep slope filter discrimination circuit
    Patent number: 9267975
    Abstract: The high speed, high accuracy capacitive gauging system employs an oscillator fed through steep slope filter that is discriminates between very small changes in capacitance even in the presence of electrical noise. During intervals when the probe tip is retracted, the oscillator frequency is calibrated to match the sweet spot in the center of the linear operative region of the steep slope filter. This calibrates the system to overcome the effects of varying temperature and humidity in the manufacturing environment.

  • Robotically operated laser head
    Patent number: 6822187
    Abstract: A laser cutting or welding device, the device having a laser head (10) and a robot (35), wherein the laser head is attached to the robot (35). The laser head (10) has a housing (12), a focal lens (26) disposed within the housing and a light source (18) in optical communication with the focal lens (26). The housing (12) has a nozzle with a tip (90), the tip having an exit port (17). The laser head (10) has means (33) for adjusting a light path of a light beam directed from the light source onto a focal optic to center a focusing beam formed by the focal optic coaxial with the tip. In one aspect hereof, the laser device has a crash avoidance system.
