| 20110089956 | Fast Response Capacitive Gauging System Featuring Steep Slope Filter Discrimination Circuit - 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. | 04-21-2011 |
| 20110088499 | Laser Head With Axial Crash Protection - An upper housing assembly includes a pivot arm having an upper cam surface adjacent a distal end. A cam follower is coupled to a laser head to move up and down with a laser head. The cam follower exerts a downward force on the upper cam surface during normal operation. Thus, as the pivot arm rotates back and forth, the laser head moves up and down. A assist gas hose can be coupled between the upper housing and the laser head which has a spiral configuration permitting relative axial movement between the upper housing and the laser head. Upon an upward axial force being exerted on the laser head, the cam follower moves upwardly away from the upper cam surface. | 04-21-2011 |
