supplied to the transducers thereby controlling the electromagnetic fields in terms of energization time de energization time and duty cycle repetition rate in addition to controlling the pemf therapy the pemf processor maintains treatment data that is available on request to the patient through a small display and to a health care professional via an i o port for monitoring and analysis for an exemplary embodiment the contoured triangular transducer is fabricated in a flat wound configuration as follows fig2 is a cross sectional view of a transducer 30 that includes primary secondary and sense windings 32 encapsulated in a semi rigid shell 34 the primary secondary and sense windings are not shown differentiated in the figure nor is the total number of windings shown meant to be accurate the figure is illustrative only for the exemplary embodiment a transducer includes two parallel primary windings of about 7 turns each a secondary winding of about 35 turns and a sense winding of at least 1 turn for the primary and secondary windings 18 gauge wire can be used while 22 gauge wire can be used for the sense winding the approximate dimensions of the winding bundle are 0 75 by 0.
