Filed:

Mar 21, 2002

Appl. No.:

10/089042

Inventors:

Vibhu Vivek - Santa Clara CA
Eun Sok Kim - Torrance CA
Yi Zeng - Fremont CA

Assignee:

University of Hawaii - Honolulu HI

International Classification:

B01F 1300

US Classification:

366108, 366116, 366127, 366341, 366DIG 4

Abstract:

A Fresnel Annular Sector Actuator (FASA) for micromixing of fluids, utilizes a self-focusing acoustic wave transducer which focuses acoustic waves through constructive wave interference. In the transducer, RF power is applied between the electrodes (sandwiching a piezoelectric film) with its frequency preferably corresponding to the thickness mode resonance of the piezoelectric film. Strong acoustic waves are generated over the electrode area, and interfere with each other as they propagate in the fluid. By proper design of the electrodes, and forming various combinations of the electrodes, wave focusing can be achieved. The mixing can be further enhanced by providing selective actuation and sequencing of the different segments by an RF signal source.

Abstract:

A micromachined acoustic transducer comprising a parylene diaphragm piezoelectric transducer. The parylene diaphragm has far lower stiffness than the silicon nitride. The method for fabricating the parylene diaphragm acoustic transducer utilizes a prestructured disphragm layer utilizing silicon nitride which is compatible with high temperature semiconductor process. A silicon nitride layer is patterned and partially removed after forming the parylene diaphragm layer in order to enhance the structural qualities of the parylene diaphragm. The diaphragm may be flat or dome-shaped.

International Classification:

B01L 3/02

US Classification:

422100, 422 63, 422 65

Abstract:

A DNA probe synthesis system may include a target holder for holding a target chip, an ejector array chip, a wash and dry station, and conveyance means for moving the target holder and the chip between the ejector array chip and the wash and dry station. The ejector array chip may include ejectors, reservoirs for containing DNA bases, and microchannels all on the same substrate. The ejectors may be Self Focusing Acoustic Transducers (SFATs).

G01P 15/12

US Classification:

7350412, 7350416, 7351433

Abstract:

A MEMS silicon inertial sensor formed of a mass that is supported and constrained to vibrate in only specified ways. The sensors can be separately optimized from the support, to adjust the sensitivity separate from the bandwidth. The sensor can sense three dimensionally, or can only sense in a single plane. Vibration cancellation may be provided.

Appl. No.:

10/940918

Inventors:

Eun Kim - Garden Grove CA, US

International Classification:

A45D 29/18

US Classification:

132076400

Abstract:

A device for sculpting the fingernail comprising a block having a front surface, a first side surface, and a second side surface. A layer of first sandpaper is placed on the front surface of the block, and a layer of second sandpaper placed on the first side surface. A layer of third sandpaper is placed on the second side surface. The first, second, and third sandpapers each have a different grit size from the other sandpapers. Also, the first side surface is curved inward to form a concave arch, and the second side surface is curved inward to form a concave arch.
