As a discrete touch sensing device, this sensor will be useful for capturing the three dimensional profile of the total contact force, such as the force of fingertip object interaction during a robotic manipulation task.
Three laser stripes with different wave length are project on the weldment, in which two red laser stripes are designed and used to measure the three dimensional profile of the weld face by the principle of optical triangulation, and the third green laser stripe is used as light source to measure the edge and the centerline of the seam by the principle of passive vision sensor.
The three improvements consist in using two dimensional profiles while searching for landmark updates, second, in adapting the shape model along the progress of the iterative search by varying the number of shape eigenvectors, and finally in running two search steps in cascade to recover from fatal starts.
By using the two dimensional profiling strategy Li et al (2006) found a large number of genes that showed coordinated changes in transcript abundance and splicing, indicating that many distinct steps in gene expression from transcription, stability control and splicing may be coupled in different cell types (Li et al, 2006).
The data collected by the scanner were pre-processed using "Autostem" software (Treemetrics Ltd., Cork, Ireland) to obtain three dimensional stem profiles in an appropriate form for making a more thorough analysis of the curvature of the tree.
The three dimensional energy profile is presented as a new conceptual model for assessment of household energy use.
The digital signal processing includes subroutines that drop down two dimensional and three dimensional beam profile displays to determine the laser beam parameters of optical power, peak pixel location, centroid location and width of the laser beam, with algorithms based on the ISO 11146 standard.
The result shows that the two- dimensional profile of complex terrains could be described by a cubic spline curve precisely.
The three dimensional hydraulic conductivity profile was determined, using a purpose made device which recreates the constant head permeameter test in-situ.
Comparison of two dimensional protein profiles was carried out as previously described [30].
Also, two dimensional chloride profiling will be used in future work, in order to more accurately relate crack width and chloride concentration in cracked SHCC.
