  • Method and apparatus for harvesting energy from mechanical vibrations
    Patent number: 7977852
    Abstract: A method of harvesting energy from a vibrational energy source having a varying energy characteristic. The method includes the step of varying a characteristic of a harvesting arrangement arranged to harvest the energy, the characteristic of the harvesting arrangement being varied in response to the varying energy characteristic of the vibrational energy source.
    Type: Grant

  • Vibrational damping apparatus and method for deriving a digital signal processing algorithm
    Publication number: 20030057807
    Abstract: A first impedance synthesizing arrangement is adapted to accept an input voltage and to provide a corresponding output current according to a predefined relationship between the input voltage and the output current. A second impedance synthesizing arrangement accepts an input current and provides an output voltage. The first and second impedance synthesizing arrangements may be utilized in the vibrational damping apparatus. When using a digital signal processor in the impedance synthesizing arrangement, it is preferable to develop an algorithm which can be used to ensure that the predefined relationship between the voltage and the current is as required.
