  • Patent number: 10466676
    Abstract: A system for adjusting a cutting tool includes a cutting system that includes a cutting tool that includes a tip configured to cut material thermoformed to a dental model. The cutting system is configured to determine, based on a cut line generated for the cutting tool to cut a dental aligner from material thermoformed onto a dental mold, a target tool vector defined by an angle of a tip of the cutting tool with respect to a surface of the dental model at the cut line, compare the target tool vector to a constraint of the cutting tool, and adjust a position of the tip of the cutting tool with respect to the cut line to compensate for the target tool vector being outside the constraint of the cutting tool.

  • Publication number: 20190118181
    Abstract: A combination of components in a capillary flow channel use capillary forces to passively control the movement of liquid samples within a microfluidic device. To detect a target, a liquid sample introduced to a proximal portion of a capillary channel of a microfluidic device moves by capillary action along the specific components of capillary channel.

The filamentary strands (36) having polymer fibers (38). The polymer fibers have, at room temperature, an elastic modulus in excess of 55 GPa so that the reinforcing strip is able to prevent radial expansion of the armor layer, when the armor layer experiences radial force; and the polymer fibers furthermore have an elongation at break in excess of 4% such that the reinforcing strip is able to undergo deformation without breaking.
