Various embodiments described above are directed to identifying abuse-hosting services at their source, rather than using such intermediaries as URLs and associated domains. The driver has a rotatable drive shaft which is configured to apply driving and rotational forces to a medical device. Of course, other claims and combinations are provided as well. In addition, this allows easy detection of a specific waveform such as P wave and T wave from the electrocardiogram diagram by using the difference between the arbitrary signal and two slope tracing wave. The information obtained from such monitoring can be used to populate databases, for example. This creates a circular or swirling motion of water within the housing which in turn imparts a rotary motion to the nozzle.
