Systems and methods for improved power profiling of embedded applications are presented. More than one and less than all of the end-user locations are themselves interconnected by a feeder, the feeder not metallically connected to the utility grid. At least the lancet point is located in a recess in the base and the recess can be closed by a cover as long as the analytical aid is in an unused state. As a result of this, the leading end of the insertion portion is inserted into the attaching hole of the balloon and hence the balloon can be easily attached to the leading end of the insertion portion of the endoscope. The power supply voltage signals may be modulated according to a predetermined lookup table during device startup so that the control circuit is configured to generate desired control signals.
