A glenoid component for a shoulder prosthesis adapted to be mounted in a glenoid cavity of a shoulder. The route includes a set of critical points including the endpoints and any decision points of the route intermediate the two endpoints. A controller infers that the width of the packaging bag has decreased when the thickness of the packaging bag is greater than a reference thickness, and the controller causes a first guide member to move so as to approach a second guide member via a guide drive part. The ECU limits the gradual change speed of the throttle opening degree for a predetermined period such that a changing speed of the engine speed is suppressed at a reverse time when a direction of torque transmitted between the driving system and the engine is reversed. In a method for operation of a shockwave system for treatment of a patient, an indicator correlated with the calmness of the patient is detected and a measure to increase the calmness of the patient is taken dependent on the indicator.
