ADIRA I4.0 Demo issues. Initial version of alerts processing. Uses two queues - one for the alerts and one for the accelerometer sensor. We assume that at least one alert must be available before we process the data. We then check if the data is within the alert window. If it is process it, Id the data is before the alert window drop it, if it is after, wait for the next alert.
