  • Patent number: 7301616
    Abstract: The present invention relates to a method and apparatus for alignment of two mechanical parts. An inventive measuring device has a housing comprising a light source and a detector for detection of light beams. The light source is capable of transmitting a light beam modulated according to a modulation scheme for information transmission. The output of said detector is connected to an interpreter arranged to demodulate a detected light beam and to a signal conditioner arranged to extract the position of impingement of a detected light beam on the detector surface.

  • Patent number: 6725723
    Abstract: The invention relates to a method for evaluating the condition of a machine (100) with a measuring point (90), which method is performed by a movable analysis apparatus (30). The method comprises the steps of producing a condition value, by means of measuring at the measuring point, which condition value is dependent on the actual condition of the machine, and storing the condition value in a writable information carrier (120) which is placed by, or in the vicinity of, the measuring point (90) so that the condition value subsequently can be used as a reference condition value. The invention further relates to an apparatus for performing the method and a device for cooperating with the analysis apparatus and for mounting by a measuring point on the machine (100).
