US Patent:

6706012, Mar 16, 2004

Filed:

Jun 7, 2001

Appl. No.:

09/876891

Inventors:

Bruce McKendry - Benicia CA
Wallace Charles Seaman - Cool CA
Sung Lee - Elk Grove CA

Assignee:

L. Jason Clute - Alamo CA

International Classification:

A61M 106

US Classification:

604 74, 604 75, 604 76, 119 1402

Abstract:

A device for expressing milk from one or more breasts has at least one, and preferably two expressers and a pump. The expressers each have a cup for fitting on the breasts and a cup outlet to which a vacuum created by the pump can be connected. The cups have a flexible liner which collapses around the breast to establish the vacuum. Pulsating pressure is applied to the outside of the liner to increase the vacuum and stimulate milk production. The pressure is applied through lines which are vented to maintain adequate, consistent pressure pulses without stalling the pump.

Appl. No.:

09/989513

Inventors:

Sung Bok Lee - Chicago IL, US
Peter V. Loeppert - Hoffman Estates IL, US

Assignee:

Knowles Electronics, LLC. - Itasca IL

International Classification:

H01L 29/82

US Classification:

257415, 438 53

Abstract:

A solid-state transducer is disclosed. The transducer comprises a semi-conductor substrate forming a support structure and having an opening. A thin-film structure forming a diaphragm responsive to fluid-transmitted acoustic pressure is disposed over the opening. The transducer further includes a plurality of semi-conductor supports and tangential arms extending from the diaphragm edge for connecting the periphery of the diaphragm to the supports. The tangential arms permit the diaphragm to rotate relative to the supports to relieve film stress in the diaphragm. The transducer still further includes a plurality of stop bumps disposed between the substrate and the diaphragm. The stop bumps determine the separation of the diaphragm from the substrate when the transducer is biased.

US Classification:

359359, 359900

Abstract:

Employing collector optics that has a sacrificial reflective surface can significantly prolong the useful life of the collector optics and the overall performance of the condenser in which the collector optics are incorporated. The collector optics is normally subject to erosion by debris from laser plasma source of radiation. The presence of an upper sacrificial reflective surface over the underlying reflective surface effectively increases the life of the optics while relaxing the constraints on the radiation source. Spatial and temporally varying reflectivity that results from the use of the sacrificial reflective surface can be accommodated by proper condenser design.

International Classification:

C12N 15/00

US Classification:

43525233, 4353201, 536 241

Abstract:

The present invention provides nucleic acids that include a promoter that is inducible by a transcriptional activator protein; and a nucleotide sequence that encodes the transcriptional activator protein. The present invention provides expression vectors that provide for inducible production of gene products in a host cell. The present invention further provides host cells genetically modified with a subject expression vector. The present invention further provides methods for producing a gene product in a host cell.

International Classification:

C30B 33/08

US Classification:

216 23, 216 87

Abstract:

A directed energy source is applied to a portion of a material, creating at least one altered region and leaving at least one unaltered region. The material is exposed to an etchant which removes the at least one altered region leaving substantially all of the unaltered region.

Appl. No.:

12/030629

Inventors:

Bruce McKendry - Benicia CA, US
Sung Lee - Sacramento CA, US

International Classification:

A61J 9/04

US Classification:

215 115

Abstract:

Baby bottles can have a single container, or two containers to create a space for thermal isolation, as selected by the user. The baby bottle can be vented to allow air to enter the bottle through a passageway as liquid is removed. A filter and one-way valve can be provided in the passageway. The passageway can be formed by radially aligning a vent opening in a top cap with a vent opening in a nipple flange, or by providing a channel in the top cap which is always in radial alignment with both the top cap vent opening and the flange vent opening.
