  • Patent number: 11185986
    Abstract: Techniques for fingertip design are disclosed that leverage how most grasp contacts can share a few classes of local geometries. In order to maximize the contact areas for achieving more robust grasps, contact primitives, which represent a set of contacts of similar local geometries, are identified. A uniform cost algorithm, which can be formulated as a decision making process in a tree structure, can be utilized to cluster a set of example grasp contacts into a finite set of one or more contact primitives. Fingertips can be designed by optimization to match the local geometry of each contact primitive, and then fingertips can be 3D printed using soft materials to compensate for optimization residuals. For novel objects, an approach to generate grasp contacts that match the fingertip geometries while together forming stable grasps can be utilized.

  • Patent number: 11162867
    Abstract: A leakage location in a viscoelastic pipe is estimated by generating a transient wave at a downstream node of the pipe. Liquid pressures at plural locations along the pipe are measured. Measured signals are transformed to frequency response functions (FRFs). The FRF from a sensor closest to the upstream node is used to estimate a FRF of transient discharge at the upstream node. A frequency-dependent wave speed of the transient wave is computed according to geometrical dimensions and viscoelastic coefficients of the pipe via the generalized Kelvin-Voigt model. FRFs of liquid pressures at the locations under a hypothetical no-leakage condition are computed according to the FRF of transient discharge and the frequency-dependent wave speed. By using the matched-field processing (MFP) method, which maximizes the signal-to-noise ratio in detection, the leakage location is estimated from the FRFs of liquid pressures.
