摘要： A hyperelastic, soft microfluidic film measures bending curvature using a novel non-differential mechanism. Disclosed embodiments of the elastomer-based solution allows for curvature sensing directly on a bending plane and thus eliminates limitations imposed by strain gauge factor (GF) and sensor thickness (Z). Due to soft lithography microfabrication and design methods the disclosed curvature sensors are elastically soft (modulus 0.1-1 MPa) and stretchable (100-1000% strain). In contrast to existing curvature sensors that measure differential strain, embodiments of the present invention measures curvature directly and allows for arbitrary gauge factor and film thickness. Moreover, the sensor is composed entirely of soft elastomer (PDMS or Ecoflex® and conductive liquid (eutectic gallium indium, (eGaIn)) and thus remains functional even when stretched to several times its natural length. Electrical resistance in the embedded eGaIn microchannel is measured as a function of bending curvature for a variety of sensor designs.

摘要： A 3-dimensional shape scanner and shape scanning method for rapidly and accurately scanning a shape of an object e.g., an artificial tooth, which requires a precise processing. The scanner of the present invention detects the contact of a probe to the object applied with electrically conductive liquid by checking the electrical conduction state to scan the shape of the object. In the scanner, a first probe (10) is installed to be electrically connected to an exterior point of the object (90), while a second probe (12) is installed to be movable around the object (90). While a position controller (30) changes the 3-dimensional position of the second probe (12) with respect to the object (90), a contact detector (40) detects the electrical conduction state between the contact of the second probe (12) to the object (90) by checking the electrical conduction state between the first and second probes (10, 12). A recorder (50) records the spacial position of the second probe (12) when the first and second probe (10, 12) is electrically connected to each other.

摘要： One measures the velocity and the displacement of an object, for example casting velocity and casting length in the continuous casting of a steel string (11) in the tough environment. In the direction of movement of the object (11), along the movement or opposite the movement, one sweeps an eddy-current inducer (12) a predetermined distance over a surface of the object with the sweep overlapping the preceding sweep and compares the received signal, that defines the topography of the surface, with the signal in the preceding sweep by means of correlation analysis so as to get the displacement that has occurred between the steps. One gets also a measurement of the friction in the mould by registering variations in the oscillation superimposed to the string as a result of the oscillation of the mould.

摘要： A method of scanning the surface (S1) of a workpiece (W) using a coordinate positioning machine equipped with a touch trigger probe (20) is disclosed. The probe is driven in a circular path toward, or away from the surface (S1) dependent upon whether or not the stylus (22) of the probe (20) is displaced from its rest position. The radius of curvature of the circular path on which the probe (20) is driven is determined in accordance with an angle between lines joining the last three points on the surface (S1) measured by the machine. The radius of curvature of the circular path is reduced with increasingly acute angles. The speed of the probe is also determined in accordance with the angle between lines joining the last three points measured by the machine; typically as the product of a maximum designated speed and the scalar product between vectors defined by lines joining the previous three measured points.

摘要： The apparatus is a co-ordinate measuring machine having a column (33) movable relative to an object (11) for determining the contour (12) thereof. A tube (15) movable relative to the column (33) has a lens (18) focussing light to a sensing point (19) intended to lie at the contour (12). When, on moving the column (33) across the contour (12), the contour (12) rises relative to the column (33) and the lens (18), the change is at first detected by an optical position sensor (23) which produces an error signal (26A) to a motor (27) causing the latter to move the tube (15) in the sense restoring the sensing point (19) to the new position of the contour (12). The movement of the tube (15) is sensed by a further position sensor (30) which outputs a signal (30Z) connected to move the column (33) in the sense of restoring its previous position relative to the tube (15). The latter signal (30Z) is shaped to produce an initially slow response in the column (33) so that the relatively greater inertia thereof is accommodated.
