| 1. A method for controlling a gastric constriction ring with a control device lacking a physical connector between the control
device and the ring, wherein the gastric constriction ring comprises an electrical motor and the control device comprises
an induction source having a power source for operating the electrical motor, comprising:
a) transmitting displacement instructions for positioning the gastric constriction ring in the form of binary data to the
gastric constriction ring by selectively interrupting an electromagnetic field generated by the induction source;
b) receiving end motor instructions from the gastric constriction ring;
c) querying the ring position to the gastric constriction ring;
d) receiving the ring position;
e) checking whether the ring position is correct; and
f) returning to a) if the ring position is not correct and turning off the control device if the ring position is correct.
