A plastic part, especially a bearing part, specifically a cage for receiving rolling bodies of a bearing. The inspection system includes an imaging system including a detector for creating and providing an image signal of the ball being inspected to an analyzer. Next, the method measures the spacers using an atomic force microscope to determine a measured spacer height. This distal end deflection may occur through various different techniques where the ability to deflect the lumen gives the operator increased control and maneuverability over the surgical implements located in the lumen. Upon receiving a user input, the communication link switches from transmitting the received radiated signal to transmitting the calibration signal. A first interworking mode involves interworking with q.
