equal or higher than Time-based acquire interval. If so, DB3 Plug&Play saves
the record to memory. If not, DB3 Plug&Play checks if the distance from the
last record to current record is equal or higher than Distance based acquire
interval. If so, saves the record to memory. If not and speed is higher than
10km/h, then DB3 Plug&Play checks if angle difference between last record
