US Patent:

6820496, Nov 23, 2004
Filed:

Apr 18, 2003
Appl. No.:

10/418987
Inventors:

James R. McElhanon - Manteca CA
Thomas Zifer - Manteca CA
LeRoy L. Whinnery - Danville CA
Assignee:

Sandia National Laboratories - Livermore CA
International Classification:

G01L 124
US Classification:

73800
Abstract:

There is provided a light emitting device comprising a plurality of triboluminescent particles dispersed throughout an elastomeric body and activated by deforming the body in order to transfer mechanical energy to some portion of the particles. The light emitted by these mechanically excited particles is collected and directed into a light conduit and transmitted to a detector/indicator means.

Castable Three-Dimensional Stationary Phase For Electric Field-Driven Applications

US Patent:

20010008212, Jul 19, 2001
Filed:

Feb 28, 2001
Appl. No.:

09/796762
Inventors:

Timothy Shepodd - Livermore CA, US
Leroy Whinnery - Danville CA, US
William Even - Livermore CA, US
International Classification:

G01N027/26
G01N027/447
US Classification:

204/451000, 204/450000, 204/454000, 204/455000, 204/469000, 204/600000, 204/601000, 204/605000, 422/100000, 422/102000
Abstract:

A polymer material useful as the porous dielectric medium for microfluidic devices generally and electrokinetic pumps in particular. The polymer material is produced from an inverse (water-in-oil) emulsion that creates a 3-dimensional network characterized by small pores and high internal volume, characteristics that are particularly desirable for the dielectric medium for electrokinetic pumps. Further, the material can be cast-to-shape inside a microchannel. The use of bifunctional monomers provides for charge density within the polymer structure sufficient to support electroosmotic flow. The 3-dimensional polymeric material can also be covalently bound to the channel walls thereby making it suitable for high-pressure applications.

Filed:

Feb 22, 2001
Appl. No.:

09/792670
Inventors:

Steven Goods - Livermore CA, US
Paul Dentinger - Sunol CA, US
Leroy Whinnery - Danville CA, US
International Classification:

G01L001/24
US Classification:

073/800000
Abstract:

There is provided a light emitting device comprising a plurality of triboluminescent particles dispersed throughout a low density, frangible body and activated by rapidly crushing the body in order to transfer mechanical energy to some portion of the particles. The light emitted by these mechanically excited particles is collected and directed into a light conduit and transmitted to a detector/indicator means.

US Patent:

20030042642, Mar 6, 2003
Filed:

Jul 31, 2002
Appl. No.:

10/210534
Inventors:

Leroy Whinnery - Danville CA, US
International Classification:

B29D009/00
US Classification:

264/045400
Abstract:

A method for providing a uniformly dense polymer foam body having a density between about 0.013 g/cmto about 0.5 g/cmis disclosed. The method utilizes a thermally expandable polymer microballoon material wherein some of the microballoons are unexpanded and some are only partially expanded. It is shown that by mixing the two types of materials in appropriate ratios to achieve the desired bulk final density, filling a mold with this mixture so as to displace all or essentially all of the internal volume of the mold, heating the mold, for a predetermined interval at a temperature above about 130 C., and then cooling the mold to a temperature below 80 C. the molded part achieves a bulk density which varies by less then about 6% everywhere throughout the part volume.

US Patent:

20040127590, Jul 1, 2004
Filed:

Dec 20, 2002
Appl. No.:

10/328316
Inventors:

Leroy Whinnery - Danville CA, US
Steven Goods - Livermore CA, US
Dawn Skala - Fremont CA, US
Craig Henderson - Livermore CA, US
International Classification:

C08J009/00
C08G018/00
US Classification:

521/159000
Abstract:

Disclosed is a polyurethane closed-cell foam composition exhibiting an ability to absorb very high strain rate compression without loss of structural integrity by brittle fracture, spalling, or splintering. The new composition further exhibits no loss or degradation in conventional mechanical properties, particularly its response to low rate compression. The new formulation of the present embodiemnt is based on the reaction product of a modified MDI isocyanate and a sucrose/glycerine based polyether polyol resin catalyzed by a mixture of one or more tertiary amines and water wherein the isocyanate and polyol resin each have a low number of functional groups per monomer and a high number of rotational degrees of freedom.

Appl. No.:

10/652647
Inventors:

LeRoy Whinnery - Danville CA, US
Steven Goods - Livermore CA, US

International Classification:

B29C044/02
C08G018/00
US Classification:

521/155000, 264/055000
Abstract:

Disclosed is a closed-cell polyisocyanurate foam composition capable of high compressive strength at temperatures up to 200 C. The new composition further exhibits no loss or degradation in conventional mechanical properties—less than that which impacts the intended use. The formulation of the present invention is based on the reaction product of a isocyanate and an epoxide resin catalyzed by a mixture of a tertiary amine and a cyclic amine. Compressive strength is augmented by incorporating a large fraction of a non-reactive bulk filler into the precursor polymer gel.
