Title: JOINT RECOGNITION SYSTEM
Abstract:
Techniques and systems to provide automatic positioning of a tripping apparatus (24). A system may include a sensor (70, 72) configured to detect a physical characteristic of a tubular string (20) moving past the sensor (70, 72) and generate a signal indicative of the physical characteristic. The system may also include a processing device (74) configured to process the signal indicative of the physical characteristic, determine whether the processed signal is indicative of a deviation of the tubular string (20), and generate output data utilized to automatically position a tripping apparatus (24) at a location of the deviation on the tubular string (20).
