Exclusive system developed by Cometa that automatically checks the impedance of the skin during the pre-acquisition phase. Each electrode has a dedicated circuit to measure the impedance of the electrode/skin contact; if it is above a reference threshold, the two-color led on the probes will turn from green to orange, signalling an excessive impedance and calling for a better placement of the electrodes or a better preparation of the patient’s skin. This can also be monitored on the PC screen. This technology, so far unheard of in the EMG market, will allow both the most experienced users and the beginners to save time and increase accuracy in their measurements.
All our EMG systems have been developed in order to have a fixed delay from the acquisition of the signal to the analog output. This means that the delay is easily removable when using the EMG synchronized with other systems. The delay does not change with the number of channels used, and it is so short that it does not affect in any way real time monitoring of the signals.

The «Diversity Mode» technology used by our EMG systems minimizes the effect of wave reflections from walls or objects; this is always present when working indoor.These reflections lead to some «black spots» in the working area, where radio signal could be lost. To get rid of this, Wave and Waveplus EMG systems are equipped with two receivers; if one receiver looses the signal due to subtractive reflections, the other is used to guarantee the best data integrity.
Our analog board (Wave Plus) is the only one in the EMG world that can carry out the data of sixty-six channels simultaneously. We use top quality components to ensure the highest quality transmission of 16 EMG, 48 accelerometers and 2 FSW.

With this technique, transmitter n. 1 is the master of synchronization, while the other transmitters are slave. Transmitter n. 1 will take the role normally reserved for the USB receiver, and will keep all other transmitters perfectly synchronized. This function is also excludable for those situation where even intra-probe communication is very difficult or impossible, for example underwater or during some outdoor activities.
The inductive recharge technique for EMG and inertial transmitter has been develop by Cometa and has been used in all our systems since 2005. The main advantage of this solution is the total absence of metal contacts on the transmitter box, allowing the design of a closed plastic container. Using this technology, Cometa has developed the first EMG and inertial transmitters that are natively WATERPROOF and can be used for heavy duty applications where dirt, sweat and other agents could compromise the normal systems.
