fiducial mark

This particular fiducial mark uses a square cutout in the silkscreen.

The actual movement of a board in and out of a machine, alignment of the board to some known target (stencil fiducial mark), movement of the board to its required position and its transport to the downstream process are typical cycle-time specifications.

Five EM-tracked fiducial marks were placed on the phantom or patient in order to create the "patient-space." In patients, the fiducial markers were placed on the patients' skin outside of the sterile field.

Also, on the left and right margin of scanned aerial photographs, fiducial marks must be clearly visible.

Up to three fiducial marks are selected in a learning procedure.

This low error probability system based in application of hyperbolic wavelet transforms and integrated circuits photo masks fiducial marks geometric moment features.

The chorobates was an elongated wooden platform, sometimes with a water-filled longitudinal groove, having plumb bobs on each end that were aligned with fiducial marks on the structure.

Sampling for calculations of the average friction is restricted to the middle portions of each cycle, as indicated by fiducial marks. The peak is taken at the start of the first cycle.
