  • Patent number: 10605700
    Abstract: A method of determining the endurance limit of an implantable medical device is disclosed. The method utilizes a mock vessel that has a compliance that is higher or lower than the normal compliance of a human vessel for which the device is to be used. The device is deployed into the mock vessel and a curable liquid is used to form a layer over the device on the surface of the lumen of the mock vessel. High pressure pulsatile pressurization is applied to the lumen of the mock vessel to cause a failure of the implantable medical device. The amount and cycles of pressure necessary to cause a failure may be used to determine the endurance limit of the implantable medical device.

  • Patent number: 9632046
    Abstract: The invention pertains to a test apparatus and method for assessing thermo-mechanical fatigue related phenomena within a test material wherein a heat source, such as a laser beam is applied to a specimen consisting of a body of the test material, thereby introducing heat to a primary heat introduction zone on the surface of the body to cause local cyclic heating. As part of the cycle, heat is removed through a portion of the specimen surface sufficiently remote from the heat introduction zone to create a substantially spherical temperature gradient within the specimen resembling that of a point source on a semi-infinite body. A stress gradient results from local thermal expansion, thus thermo-mechanically cycling the material. As a result of the thermo-mechanical cycling, phenomena including thermo-mechanically induced creep, residual stress, changes in physical properties, crack initiation and crack growth may be observed within the material, and evaluated for scientific or engineering purposes.

  • Patent number: 8915143
    Abstract: The scientific characterization of cellular contractility and cell movement, such as muscle function in particular is, to a large extent, carried out on intact tissue preparations for example using whole intact muscles from animals. Typical indices of muscle function may include isometric force, contractility under external force (load) and spatio-temporal determination of internal calcium concentration under strictly controlled conditions of length and applied force. The major advance of the described apparatus is that the common characterization of cellular contractility can be performed on a single cell rather than an entire tissue or whole animal. As such the apparatus described improves on and eliminates known limitations of currently considered state-of-the-art approaches.

  • Publication number: 20140361883
    Abstract: A collision sensor assembly is attachable to a stationary structure such as a pallet rack, a door frame, the corner of a wall, or the like. The collision sensor is configured to sense when a collision occurs with the stationary structure such as when a piece of movable machinery contacts the stationary structure. The collision sensor assembly includes a sensor operatively connected to a processor which determines when a collision occurs, and produces a signal to an output signal generator to provide an external indication of the collision.

  • Patent number: 8890516
    Abstract: A tension measurement apparatus that can carry out tension measurement of superior reproducibility with high sensitivity even for a target object of a stranded wire structure is provided. A cylindrical magnetizer arranged to surround a portion of a long magnetic element that becomes the target object of measurement direct-current magnetizes the magnetic element in the longitudinal direction up to the range of approach to saturation magnetization. Using a Hall element (magnetic sensor) arranged in proximity to the magnetic element at the central region in the longitudinal direction of the magnetic domain, the spatial magnetic field intensity in the neighborhood of the surface of the magnetic element, greatly differing corresponding to stress variation, is detected. Based on the detection value, the tension acting on the magnetic element is measured. Accordingly, a measurement result of superior reproducibility with high sensitivity is obtained.

  • Patent number: 8875366
    Abstract: A method for evaluating local buckling performance of a steel pipe includes obtaining a stress-strain relationship of a material having a yield plateau in the stress-strain relationship; determining the comparison of a starting strain of strain-hardening in the stress-strain relationship obtained and a critical strain of the steel pipe; and evaluating that the steel pipe has a possibility of being applied to a structure that requires plastic design when the critical strain is determined to be larger than the starting strain and evaluating that the steel pipe has no possibility of being applied to a structure that requires plastic design when the critical strain is determined to be not larger than the starting strain.

  • Patent number: 8833173
    Abstract: The present invention defines a strain sensor for measuring strains induced on a component surface (34). The strain sensor comprises a strain gauge (31) and a support member (32), whereby the support member is attached to the component surface only at first and second attachment places. The support member comprises a beam portion (39) that is adapted to bend in response to a relative displacement of the first and second attachment places, and the strain gauge is integrated on a surface (33) of this beam portion. To ensure a strong and stable bending response of the beam portion, the attached support member comprises at least one flexure hinge (45).
