  • Patent number: 10837770
    Abstract: A measuring device for measuring an object. The measuring device includes a distance measuring unit having a beam emission unit generating a measurement radiation having a defined wavelength spectrum and a detector detecting the measurement radiation reflected on the object surface, the detector having at least one first sensor. The distance measuring unit generates distance measured data and reflection measured data as first distance measured data by emitting the measurement radiation and detecting the reflected measurement radiation according to the principle of triangulation. The measurement radiation is generated using a wavelength spectrum such that a fluorescence is excitable by an interaction of the measurement radiation with the object material to emit fluorescent light, wherein a spectrum of the fluorescent light and the wavelength spectrum of the measurement radiation are different.

  • Patent number: 10719537
    Abstract: A large number of objects, such as objects representing beams and columns in an object-oriented enterprise engineering system, may be geometrically transformed in a model database by dividing the objects according to criteria into a number of ordered partitions and transforming the objects in each partition as an atomic operation. The number of objects that may be transformed is not constrained by the amount of memory available in the system. Objects that are to be transformed are organized into the ordered partitions, and the partitions are transformed in sequential order, such that all predecessors of a given object are transformed before, or in the same operation as, the given object. If a large transformation operation abnormally terminates before all the small transformation operations have been completed, the model database is, nevertheless, left in a consistent state. The transformation operation may be resumed from the point of interruption.
