A surface analysis apparatus and a method for compensating for mechanical vibrations and drifts in a surface analysis instrument are disclosed. A probe that is sensitive to the distance between the probe and a sample surface provides a probe signal. The probe signal contains information about the surface properties and noise due to changes in the probe-surface distance. A sensor measures a displacement between a probe and the sample surface.

A latching mechanism for variably activating an engine valve in an internal combustion engine includes a rocker arm body having a bore and a socket. A first passage leads from the socket to a first hydraulic chamber formed above a lock pin head. A second passage leads from the socket to a second hydraulic chamber formed below the lock pin head. Since both the first and the second hydraulic chamber receive pressurized oil, it is the diameter of the pin shank that determines the hydraulic force needed to axially move the locking pin to an extended position and into a locking engagement with a slider member. In an alternate embodiment of the invention the first passage connecting the first hydraulic chamber with the socket is eliminated and instead the locking pin is modified to permit flow between second hydraulic chamber and first hydraulic chamber.
