  • Patent number: 9588020
    Abstract: A method of testing a shape memory alloy (SMA) actuated device includes cyclically operating the device. The method further includes determining a number of cycles in a functional life of the device based on observations of the device during the cyclical operation. The functional life is a range of consecutive cycles of operation of the device beginning with a first cycle during which the device performs within a specified limit. The functional life is immediately followed by a cycle during which the device performs outside of the specified limit. The method still further includes applying a progressive substitution sub-process to identify an opportunity to increase the number of cycles in the functional life of the device.

  • Patent number: 8360208
    Abstract: A synthetic fiber rope can be used to the limit of failure by setting a sensitivity of detection of the state of wear of the rope. Strands of the rope have indicator fibers or indicator yarn that have a high probability of losing electrical conductivity and thereby indicate a worn cable. The indicator yarn consists of indicator fibers and of synthetic fibers, the indicator yarn fibers being inferior in relation to stress than the synthetic fibers of the strands.
