  • Multi-layer ceramic acoustic transducer
    Patent number: 7148608
    Abstract: A method for manufacturing a multi-layer acoustic transducer with reduced total electrical impedance. The method is based on the bonding of two piezoelectric ceramic layers with confronting metallized surfaces to a thin electrical conductor, then electrically connecting the top and bottom surfaces to form a wrap-around electrode while a center conductor forms a second electrode. The total electrical impedance of a two-layer ceramic stack comprised of piezoelectric layers connected in this manner is one-fourth that of a solid ceramic element of the same size. This provides for better matching of the acoustic stack impedance to that of the electrical cable, increased penetration depth for imaging within the body, and improved acoustic element sensitivity.

  • Rail based electric power generation system
    Patent number: 7148581
    Abstract: An electrical power generation system comprises a variable capacitor and a power source. The electrical power generation system is configured to generate electric power via movements of the rail. The power source is used in the form of a generator to prime the variable capacitor that effectively multiplies the priming energy of the power source by extracting energy from the passing vehicle. By alternately priming the variable capacitor using charge from the power source and discharging it at a later time in a cyclic manner to change the capacitance, a significantly large amount of electrical energy is produced due to change in capacitance than from the power source itself.

  • Angled implant in a fabrication technique to improve conductivity of a base material
    Patent number: 7148534
    Abstract: Ion implantation may be used to break up a dielectric layer that forms during the fabrication of a memory array. More specifically, during the fabrication of wordline stacks, a nitride layer may form between the polysilicon layer and the conductive metal layers above the polysilicon layer. While the nitride layer may be desirable during the fabrication process, it may inhibit electrical conductivity between the polysilicon layer and the conductive metal layers. A two step etch process may be implemented wherein the wordline stacks are etched into the polysilicon layer in the first etch and etched down to the substrate during the second etch. An angled implant may be used to break up the nitride layer between the first etch and the second etch.
