摘要： In one general aspect, a computer-readable storage medium can be configured to store instructions that when executed cause a processor to perform a process. The instructions comprising instructions to trigger flow of an alternating current having a waveform defining a range of frequencies from a waveform generator to a reinforcing bar embedded within concrete via a probe coupled to a surface of the concrete, and receive an indicator of a time-resolved current magnitude of the alternating current through a portion of the concrete associated with the surface of the concrete.

摘要： A flexible electric probe can include: a flexible substrate; and probe line conductors on the flexible substrate, the probe line conductors being essentially parallel to each other and having separations of about 5-50 microns. The flexible electric probe can further include connection conductors on the flexible substrate, the connection conductors and the probe line conductors electrically connected to each other, the probe line conductors positioned in first and second offset patterns with regard to the connection conductors.

摘要： A flexible electronics assembly includes a single-piece substrate having two regions of rigidity separated by a localized region of flexibility. The localized region of flexibility has a lower rigidity than the two regions of rigidity. The two regions of rigidity are angularly deflectable from a planar configuration of the single-piece substrate to a non-planar configuration of the single-piece substrate by hinging action of the localized region of flexibility. At least one electronic component is mounted on at least one of the two regions of rigidity.

摘要： Techniques of refining a model of a complex surface can include deriving a set of refinement rules based on eigen polyhedra in a plane. Such rules reduce the refinement of a mesh in the plane to a scale and translation of the eigen polyhedron. Such refinement rules may then be applied to a non-uniform mesh in three-dimensional space having an extraordinary point in place of conventional refinement rules used in Catmull-Clark surfaces or NURBS surfaces. When these refinement rules are applied to a non-uniform mesh having an extraordinary point, the limiting surface is G1 at the extraordinary point, i.e., the tangent surfaces of the limiting mesh are continuous at the extraordinary point.

摘要： A lamina emergent torsional (LET) joint that includes an integrated membrane to reduce, or eliminate, certain unwanted motions and/or displacements associated with the operation of the LET joint is disclosed. The membrane-integrated LET joint (i.e., M-LET) can be used as a hinge for a lamina emergent mechanism and/or as a surrogate fold for an origami application to ensure accurate and repeatable transitions from a planar (i.e., lamina) state to a non-planar (i.e., lamina-emergent) state, and vice versa.
