This patent relates to a mobile terminal and a method of controlling an operation of the same. The first dimension is greater than the nominal pitch value, thereby assuring electrical contact between the contacts and the contact surfaces despite an actual deviation from the nominal pitch. The gearwheel teeth each have a first contour and tooth flanks with respect to rotation of the gearwheel. A voltage-to-current converter converts the voltage of the loop filter to a current. This medical kit may include a catheter having a channel and a piercing tip, the piercing tip in fluid communication with a pressure source and slidably placed in the channel.
