  • Patent number: 7514804
    Abstract: A method of harvesting vibrational energy is provided. This method involves generating a high magnetic flux density field within a current induction conductor such as an induction coil. The high magnetic flux density field is generated between two same pole magnets. The high magnetic flux density field may be displaced relative to the current induction conductor with vibrational energy. These displacements then cause the current induction conductor to be energized. The two same pole magnets are mounted between piezoelectric transducer (PZT) materials. These PZT materials generate an electric potential when the PZT materials are subject to the mechanical stresses of the vibrational energy. The electrical energy translated from the vibrational energy through both the energized current induction conductor and stress PZT materials may then be used to power a power circuitry or be stored for later use.

  • Patent number: 6402093
    Abstract: A dielectric coating is applied to a surface that is prone to icing. Ice detecting sensors are deployed over the surface that is in danger of excessive icing. When sensors detect the presence of ice, a charge opposite that of the ice coating is automatically applied to the surface beneath the dielectric coating. Since ice in its natural state is a negatively charged substance, an identical, negatively charged surface repels or loosens the ice.
