In one embodiment of the present invention, a computer-implemented method for obtaining a command of a user includes capturing an image of the eyes of a user. The invention proposes a method for manufacturing, adapting or adjusting a bearing portion in a fluidal microcomponent comprising a stator and a rotor. Such a capability allows the electrical isolation to be measured both during the lapping process and subsequent to the heads being diced into separate sliders. A bumper is slidably supported within the cradle.
