Filed:

Mar 10, 2011

Appl. No.:

13/044781

Inventors:

Allan Roberts - Buena Park CA, US
Weixing Lu - Los Angeles CA, US

International Classification:

F03B 13/12
H01L 1/00

US Classification:

290 53, 310309

Abstract:

One embodiment of the present invention consists of a system of small, interconnected cubes, each containing interior walls made from a highly sensitive multi-layer piezoelectric material and each having heavy mass, such as stainless steel, inside the cube interior. An elastic material layer covers the heavy internal mass that is in contact with the piezoelectric cube walls. As the system moves with the water, the heavy mass inside each cube exerts varying inertial forces on the cube walls causing a piezoelectric current to be generated. However, the cell walls may also be constructed using commercially available piezoelectric materials. This approach is a second embodiment of the current invention and includes the same system design as the first embodiment except that the internal cubic cell walls are fabricated in a unique manner using commercially available piezoelectric materials, rather than the non-central symmetric LB poly-vinylidene fluoride (PVDF) multilayer piezoelectric material.

Allan Roberts - Buena Park CA, US

International Classification:

H02N 2/00

US Classification:

310339

Abstract:

In a first embodiment, a wind to energy conversion system is constructed out of a number of modular power units (), each modular power unit () comprised of 36 air jet tunnels (). Each air jet tunnel () is constructed using a cantilever array mounted in a cascaded frame () with each cantilever () attached on one edge to a window edge of the frame (). The cantilever () is constructed of a brass () layer sandwiched between two layers, each layer composed of an electrode () attached to a Poly Vinylidene Fluoride (PVDF) () layer. Each modular power unit () is mounted in a case (), and a set of cases are mounted in a panel () attached to a pedestal (). The cantilever arrays () are wired together into electrical regulating circuits that generate power with a high wind to power conversion efficiency. Other embodiments are presented.

International Classification:

B05D 5/00
B05D 3/02
B05D 3/10

US Classification:

427535, 427301, 427302

Abstract:

The field of the invention relates to systems and methods for surface treatments, and more particularly to systems and methods for surface treatments, modifications or coatings using micro- and nano-structure particles for both super-hydrophobic and super-oleophobic properties. In one embodiment, a method of treating surfaces to impart both super-hydrophobic and super-oleophobic properties includes the steps of pre-treating a substrate surface; assembling dual-scale nanoparticles onto the surface of the substrate; and treating the dual-scale nanoparticle coated surface with SiClto cross-link the nanoparticles to each other and to the surface of the substrate creating a robust nano-structured topographic surface having both super-hydrophobic and super-oleophobic properties.
