US Patent:

8439654, May 14, 2013

Filed:

Dec 28, 2006

Appl. No.:

11/646680

Inventors:

Hyun Cho - Katy TX, US

Assignee:

Kellogg Brown & Root LLC - Houston TX

International Classification:

F04B 17/00
F04B 35/00

US Classification:

417360, 4174233, 62 506

Abstract:

A method and system for pumping liquefied gas are provided. The system for pumping liquefied gas can includes a container having an access port with a central axis disposed at an upper end thereof, a pump disposed within the container, and at least one pipe segment having a first end and a second end. The pump can include a fluid inlet in fluid communication with a liquefied gas stored in the container and a fluid outlet. The first end of the pipe segment can be in fluid communication with the fluid outlet of the pump. The second end of the pipe segment can be in fluid communication with an exterior of the container. The pump can be capable of lifting the liquefied gas through the at least one pipe segment and discharging the liquefied gas from the container at a pressure sufficient for distribution or further processing.

Appl. No.:

11/646875

Inventors:

Hyun Cho - Katy TX, US
Felix J. Fernandez de la Vega - Houston TX, US

International Classification:

B23P 17/00

US Classification:

137 14

Abstract:

A method for pressurizing vapor from a liquefied gas is provided. At least a portion of a storage tank overhead vapor stream can flow to an eductor and at least a portion of a hydrocarbon liquid stream can flow to the eductor. The hydrocarbon liquid stream can have a higher pressure than the vapor stream. The vapor stream and the hydrocarbon liquid stream can be combined within the eductor to provide a mixed stream. The mixed stream can be pressurized within the eductor.

Appl. No.:

15/244980

Inventors:

Hyuck Choo - San Marino CA, US
Hyun Jun Cho - Pasadena CA, US

International Classification:

H01L 41/04
A61N 1/378
H02N 2/18
H01L 41/113
H01L 41/187

Abstract:

Apparatus and methods are provided for the generation of electrical power from acousto-mechanical vibrations originating from the vocal folds of the human body. The apparatus and methods can include one or more beams comprising a piezoelectric material, such as lead zirconate titanate (PZT), coupled to a power circuitry. Each of the one or more beams can also have a predetermined resonance frequency that is within the dominant frequency range of the human voice. The power circuitry can be adapted to receive the electrical charge received by the one or more piezoelectric beams and to convert the electrical charge into an electric current. The power circuitry can also be coupled to a battery for the storage of the converted energy, which in turn can provide power to implantable medical electronic devices (e.g., neurostimulators or cochlear implants) and/or wearable electronics. Numerous piezoelectric beam shapes, device packaging structures and array configurations are also disclosed that can provide improved power generation and reduced damping effects.
