An air bearing for movably bearing at least two elements includes a bearing main body with a first air outflow channel and a second air outflow channel. The first air outflow channel is supplied with air via at least one first air delivery device. The second air outflow channel is supplied with air via at least one second air delivery device. A sensor detects at least one of a bearing stroke, a bearing pressure, and a bearing throughflow, and a controller adjusts the supply of the air to at least one of the first air outflow channel and the second air outflow channel in accordance with the at least one of the bearing stroke, the bearing pressure, and the bearing throughflow.

The invention relates to an arrangement for at least partially compensating a torque caused by gravitational forces acting on a mass body (), which is rotatably supported on an axis of rotation (). The arrangement includes a gas pressure spring () for providing a linear force. This linear force is transformed into a torque by means of a converter unit (). The mass body () and the converter unit () can be coupled to each other in a way which allows for adjusting the amplitude and the phase of a compensating torque.

A sensor module for a probe of a tactile coordinate measuring machine has a stationary module base which defines a first measurement plane. The sensor module has a support, which is moveable relative to the module base, for holding a stylus. At least one deformable connecting element movably interconnects the support and the module base. The connecting element has at least a first and a second deformable material layer which, perpendicular to the first measurement plane, are arranged offset with respect to each other. In a preferred embodiment, the sensor module is made from two single-layer module parts arranged above and attached to one another.

A probe head for a coordinate measuring machine has a replaceable, miniaturized probe system with a stylus. The stylus is rigid and forms a structural unit together with a membrane-type sensor system that is deformed in a predetermined way when a force acts on the stylus. The structural unit is permanently fixed to a probe holder and can be handled together with the probe holder when the stylus is being replaced.

A coordinate measuring machine for the metrological determination of a measurement coordinate on a test object comprises a table for mounting the test object. A first and a second bearing support are arranged on the table. A first and a second carriage, each moveable in a longitudinal direction, are mounted on the bearing supports. According to one aspect of the invention, the carriages are each mounted on the bearing supports via at least three, preferably four separate bearing points, with the bearing points defining a plane that is perpendicular to the plane of the table.

A sensor module for a probe head of a tactile coordinate measuring machine has a frame forming a stationary module base, thereby defining a first measurement plane. A moving part is connected to the frame via webs. Each web has a thick-material web portion arranged between two thin-material web portions, if seen in a cross section perpendicularly to the first measurement plane. The thick-material web portion has a material thickness greater than the corresponding material thickness of the thin-material web portions.

A carrier system () for a medical apparatus () is disclosed. The carrier system includes rotation joints (). A supply line harness runs in the carrier system () and is run so that it is covered. The rotation joint () includes a tube-shaped holding member on which fingers are formed which hold a rotation joint. A joint element, which is rotatably journalled in a joint receptacle, is provided in the rotation joint (). The joint element has a wave-shaped section which is connected via a connecting section to an annularly-shaped section functioning to accommodate a connecting arm.
