ECS halt
As soon as a proximity detection is triggered, the ECS should be halted otherwise the ECS
considers the signal variation due to the user action as an environment change. In such a
case, the ECS adapts to the new conditions until the reference reaches the current signal
level generated by the user. This leads to a detection loss as described in
Figure 13. ECS halt
The dashed lines in
this case, detection is lost before the user exits the electrode detection area. The plain lines
represent normal device processing with the ECS stop.
