A disc brake assembly having a guide pin disposed in a bore of an anchor bracket such that a guide pin axis is offset relative to a bore axis whereby there is provided at least one defined point of contact between only a portion of the guide pin and a portion of an inner surface of the bore. The user can move the device relative to the artery until the feedback signal is given, and thus a correct positioning of the measuring unit relative to the artery is achieved in an easy manner. Each combination of actions the planner considers is called a search node, with each node containing a plan representing a series of actions of various machines on a single object and also containing the predicted state of the object with those actions applied either forward or backward. The middle portion and the current blades are integrally formed of a conductive material. A film thickness of the insulator pillar in a lateral direction is thicker than a film thickness of the gate dielectric film in a lateral direction.
