A vibration based power generator. In a described embodiment, an electrical power generating system includes a vibrating assembly including a vortex shedding device which sheds vortices in response to fluid flow across the vibrating assembly. A generator generates electrical power in response to vibration of the vibrating assembly. The vortex shedding device sheds the vortices at a frequency which is substantially equal to a resonant frequency of the vibrating assembly.

Vibration based power generator

A method and apparatus for determining an electrical property of a structure. The method involves creating a model of an electrical property of a structure and measuring the electrical property of the structure between at least two of a plurality of locations. The method also involves determining the electrical property of at least a portion of the structure based on the model and the measurement of the electrical property between the at least two of the plurality of locations.

Method and apparatus for determining electrical properties of structures

A method and sheet-like sensor for measuring stress distribution including a grid of members which change in resistance when subjected to strain, the members intersecting at internal nodes and intersecting at boundary nodes at the periphery of the grid defining a plurality of legs. An analyzer is electrically connected only to the boundary nodes and configured to calculate any change in resistance in all of the legs based solely on the measured resistance of the legs between the boundary nodes.
