Fixed delay

All our EMG sys­tems have been devel­oped in order to have a fixed delay from the acqui­si­tion of the sig­nal to the ana­log out­put.

Diversity receiver

The «Diver­sity Mode» tech­nol­ogy used by our EMG sys­tems min­i­mizes the effect of wave reflec­tions from walls or objects.

Inductive charge

The inductive recharge technique for EMG and inertial transmitter has been develop by Cometa and has been used in all our systems since 2005.

Synch data logger

With this technique, transmitter n. 1 is the synchronization master, while the other transmitters are slave.
