Title: Apparatus and method for performing electrodynamic focusing on a microchip

Abstract

A microchip device includes a focusing channel, in which an electric field strength established in the focusing channel is controlled relative to an electric field strength established in a material transport channel segment to spatially focus the material traversing the material transport channel segment.

Method and apparatus for dynamic focusing of ultrasound energy

Patent Candy, James V [Danville, CA]

Method and system disclosed herein include noninvasively detecting, separating and destroying multiple masses (tumors, cysts, etc.) through a plurality of iterations from tissue (e.g., breast tissue). The method and system may open new frontiers with the implication of noninvasive treatment of masses in the biomedical area along with the expanding technology of acoustic surgery.

Focused ion beam source method and apparatus

Patent Pellin, Michael J [Naperville, IL]; Lykke, Keith R [Gaithersburg, MD]; Lill, Thorsten B [Sunnyvale, CA]

A focused ion beam having a cross section of submicron diameter, a high ion current, and a narrow energy range is generated from a target comprised of particle source material by laser ablation. The method involves directing a laser beam having a cross section of critical diameter onto the target, producing a cloud of laser ablated particles having unique characteristics, and extracting and focusing a charged particle beam from the laser ablated cloud. The method is especially suited for producing focused ion beams for semiconductor device analysis and modification.

Apparatus, systems, and methods for ultrasound synthetic aperature focusing

Patent Schuster, George J.; Crawford, Susan L.; Doctor, Steven R.; ...

One form of the present invention is a technique for interrogating a sample with ultrasound which includes: generating ultrasonic energy data corresponding to a volume of a sample and performing a synthetic aperture focusing technique on the ultrasonic energy data. The synthetic aperture focusing technique includes: defining a number of hyperbolic surfaces which extend through the volume at different depths and a corresponding number of multiple element accumulation vectors, performing a focused element calculation procedure for a group of vectors which are representative of the interior of a designated aperture, performing another focused element calculation procedure for vectors corresponding tomore » « less

Ultrasonic inspection apparatus and method using a focused wave device

Patent Gieske, John H [Albuquerque, NM]; Roach, Dennis P [Albuquerque, NM]; Walkington, Phillip D [Albuquerque, NM]

An ultrasonic pulse echo inspection apparatus and method for detecting structural failures. A focus lens is coupled to the transducer to focus the ultrasonic signal on an area to be inspected and a stop is placed in the focus lens to block selected ultrasonic waves. Other waves are not blocked and are transmitted through the structure to arrive at interfaces therein concurrently to produce an echo response with significantly less distortion.
