Patent Numbers 7,891,597 and 7,997,521 Awarded for “tension Control System for a Continuous Winding Machine”

August 2011: Dale Henson, of San Jose CA, used this technology to enable wireless control of tension on a spinning wind head powered by a rotary transformer as designed by a former satellite design engineer.  The wireless communication allows tension set points to be changed remotely while the new system maintains the linked servo loops necessary to maintain tension accuracies of +/- 1 gram down to a value of 5 grams.  This new system can also communicate using Modbus or Ethernet for use in the 503 model coil winders.
