  • Patent number: 10697941
    Abstract: Method and system are disclosed for characterizing and quantifying composite laminate structures. The method and system take a composite laminate of unknown ply stack composition and sequence and determine various information about the individual plies, such as ply stack, orientation, microstructure, and type. The method and system can distinguish between weave types that may exhibit similar planar stiffness behaviors, but would produce different failure mechanisms. Individual ply information may then be used to derive the laminate bulk properties from externally provided constitutive properties of the fiber and matrix, including extensional stiffness, bending-extension coupling stiffness, bending stiffness, and the like. The laminate bulk properties may then be used to generate a probabilistic failure envelope for the composite laminate.

    Abstract: The present invention reduces noise generated by a phase change in an ultrasonic wave focusing apparatus that changes an ultrasonic wave focal point within a space by changing the phase of vibration of a plurality of ultrasonic transducers. When inputted position coordinates within a three-dimensional space are changed, the ultrasonic wave focusing apparatus calculates a target time lag Tnew that allows ultrasonic waves outputted from the ultrasonic transducers to form a focal point at the changed position coordinates X1, Y1, Z1. The ultrasonic wave focusing apparatus then examines the ultrasonic transducers to locate a particular ultrasonic transducer that outputs an ultrasonic wave whose time lag Ttmp differs from the target time lag Tnew, and changes the phase of the outputted ultrasonic wave to a target phase in multiple steps (steps 140 and 150).

The reflected energy pulse travels through the platen to the detector. The detector converts the reflect energy pulse to electric signals, which are then interpreted to create an image of the biological object.

  • Patent number: 10492771
    Abstract: A surgical tool with a bendable shaft. At least one inelastic cable and at least one elastic cable extend along the shaft. The shaft moves relative to the body to which the shaft is attached. When the shaft is so displaced, the shat bends around the inelastic cable. The inelastic and elastic cables cooperate to hold the bendable section of the shaft in compression so the bendable section of the shaft resists deformation.

  • Patent number: 10489673
    Abstract: A method and apparatus for detecting vascular landmarks in a 3D image volume, such as a CT volume, is disclosed. One or more guide slices are detected in a 3D image volume. A set of landmark candidates for multiple target vascular landmarks are then detected based on the guide slices. A node potential value for each landmark candidate is generated based on an error value determined using spatial histogram-based error regression, and edge potential values for pairs of landmark candidates are generated based on a bifurcation analysis of the image volume using vessel tracing. The optimal landmark candidate for each target landmark is then determined using a Markov random field model based on the node potential values and the edge potential values.
