Abstract: An apparatus (10) for holding a tire in a tire balancing machine includes a base (12) that receives a locking member (14). When locking member (14) is positioned in base (12), a tire is secured between an upper rim (16) and a lower rim (18). Base (12) includes an inner sleeve (20) carrying ball bearings (22) in channels (28) therein. An outer sleeve (30) is positioned around inner sleeve (20) and is moveable between an unlocked position and a locked position. Outer sleeve (30) urges movement of the ball bearings (22) through the channels (28) in the inner sleeve (20), to particularly allow movement of inner ball bearings (22A) into and out of receptive grooves (78) in the outer surface of a locking base (66) of the locking member (14).

Abstract: A haptic operating device particularly for motor vehicles, having a touch panel having at least one touch-sensitive area. When the area is touched, a switching signal can be triggered and the touch panel can be activated by a motion drive to be able to move at a certain rhythm in the plane of the touch panel. The touch panel is connected to a fixed support by one or more flexible connecting elements. The support and the touch panel form two housing parts of a closed housing, in which at least the display device or the display plane thereof is arranged, and are connected to each other by a sealing device so as to be able to move relative to each other in the plane of the touch panel or in a plane parallel to the touch panel.
