The method can also include determining a condition of the industrial asset based on a 3D digital twin of the industrial asset. The 3D digital twin can be generated using second data acquired prior to the first data. The digital twin can include at least one 3D digital instance of at least one component of the industrial asset and a list of components of the industrial asset described according to a pre-defmed taxonomy associated with the industrial asset. The method can also include providing the condition of the industrial asset. Related apparatuses, systems, and computer-readable mediums are also provided.

Verfahren zur messung räumlicher lage und/oder abmessung einer durchbrechung eines werkstückes

Die Erfindung bezieht sich auf ein Verfahren zur Messung räumlicher Lage und/oder Abmessung einer Durchbrechung wie Bohrung eines Werkstückes im Durchlichtverfahren unter Verwendung zumindest eines optischen Sensors. Um mit konstruktiv einfachen Maßnahmen Durchbrechungen wie Bohrungen mit hoher Präzision vermessen zu können, wird vorgeschlagen, dass zumindest zwei parallel verlaufende Schnitte zwischen aus der Durchbrechung austretendem Lichtkegel und zumindest zwei Arbeitsebenen von optischen Sensoren gemessen und aus zwischen Mittelpunkten so ermittelter Kurven verlaufender Geraden Achsrichtung der Durchbrechung berechnet wird.

Verfahren und vorrichtung zur bestimmung der geometrie eines objektes mit einer telezentrischen zoomoptik

Die Erfindung bezieht sich auf ein Verfahren zur Messung der Geometrie eines Objekts mittels eines Koordinatenmessgeräts mit einem optischen System, das eine Zoomoptik umfasst, deren Linsengruppen jeweils motorisch in Stellung für einen unabhängig voneinander wählbaren Abbildungsmaßstab und einen wählbaren Abstand zum Gegenstand separat bewegt werden. Zusätzlich wird zumindest eine Blende motorisch so in Stellung gebracht, dass abhängig von der Stellung der Linsengruppen zumindest eine objektseitig telezentrische Abbildung erzielt wird.

Ink printing apparatus

In a printing apparatus a print bar assembly is provided with multiple print bars, a designed space being present between the print bars and a recording medium. A climate control has a feed channel running parallel to a length of the recording medium. Openings lead from the feed channel to the print bars to introduce a conditioned gas flow of predetermined temperature and moisture to the print bars such that a laminar gas flow is generated in the designed space between nozzle plates of the print bars and the recording medium. A barrier is arranged at an intake of the print bar assembly which blocks an air boundary layer entrained with the moving recording medium before the print bar assembly.
