Assignee:
Visyx Technologies, Inc. - Sunnyvale CA
International Classification:
G01N 11/16
US Classification:
73 5441, 73 5305, 73 6442
Abstract:
A sensor for sensing one or more properties of a vehicle fluid has a tuning fork resonator adapted to contact the fluid. The tuning fork resonator comprises two tines and is operable to oscillate so that the two tines move in opposite phase at a frequency of less than 1 MHz while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. In another aspect, a sensor includes a substrate and a flexural resonator on the substrate and adapted to contact the fluid. Circuitry for operation of the resonator is on the substrate. The resonator is adapted to receive an input signal and to oscillate while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. One suitable application for the invention is monitoring the condition of a vehicle engine oil.

Filed:
Sep 27, 2004
Appl. No.:
10/951252
Inventors:
Leonid Matsiev - San Jose CA, US
Oleg Kolosov - San Jose CA, US
Mark D. Uhrich - Redwood City CA, US
William Rust - Mountain View CA, US

Assignee:
Visyx Technologies, Inc. - Santa Clara CA
International Classification:
F25B 49/00
F25B 41/04
G01N 29/02
US Classification:
62129, 62225, 73 2401, 73 5441
Abstract:
A system for monitoring a fluid in an environmental control system includes a mechanical resonator positioned for contacting a thermal change fluid. In some embodiments, the mechanical resonator is positioned in a passage for containing the thermal change fluid. Suitable thermal change fluids include an R-134A refrigerant, a mineral oil, an ester lubricant or a mixture thereof; a superheated refrigerant; or an elevated pressure and elevated temperature vapor, an elevated pressure liquid, a reduced pressure liquid, a reduced pressure vapor and combinations thereof. The mechanical resonator can be a flexural resonator or a torsion resonator. In some embodiments, the mechanical resonator is a tuning fork resonator. Methods of the invention include monitoring a response of the mechanical resonator to the thermal change fluid. In some embodiments, at least a portion of the mechanical resonator is translated through the thermal change fluid and the response of the resonator to the fluid is monitored.

US Patent:
7549978, Jun 23, 2009
Filed:
May 16, 2005
Appl. No.:
11/131277
Inventors:
Eric D. Carlson - Cupertino CA, US
Peijun Cong - San Jose CA, US
Peter J. Desrosiers - Santa Clara CA, US
J. Christopher Freitag - Santa Clara CA, US
John F. Varni - Los Gatos CA, US
Assignee:
Symyx Technologies, Inc. - Santa Clara CA
International Classification:
A61M 5/31
A61M 5/00
US Classification:
604156, 604507, 604403, 604110, 604 88, 604162, 604158, 422100, 600562
Abstract:
A needle assembly has a first body and a guide rod supported for sliding movement between an extended position and a retracted position. A second body is attached to the guide rod. The second body is relatively farther from the first body when the guide rod is in the extended position and relatively closer to the first body when the guide rod is in the retracted position. The guide rod is biased to the extended position. The second body supports a venting needle that extends beyond the second body by a fixed length. A liquid handling needle is coupled to the first body. Sliding movement of the guide rod toward the retracted position retracts the second body and the venting needle relative to the liquid handling needle.

Abstract:
An improved method and assembly, wherein the method generally includes the steps of providing a coated or uncoated sensor element having an exposed sensing surface; attaching the sensor element to a platform so that the exposed sensing surface is spaced from the platform; and optionally applying a protective layer over the platform while maintaining the sensing surface as exposed. The assembly includes a resonator having a free portion with a sensing surface is incorporated onto a platform, components of the sensor are physically shielded from harsh operating conditions, the requisite space is maintained between the free portion of the resonator and the platform, and the sensing surface of the resonator remains exposed for sensing.

Filed:
May 24, 2002
Appl. No.:
10/156245
Inventors:
Eric Carlson - Cupertino CA, US
Peijun Cong - San Jose CA, US
William Chandler - Milpitas CA, US
Peter Desrosiers - Santa Clara CA, US
J. Christopher Freitag - Santa Clara CA, US
John Varni - Los Gatos CA, US
International Classification:
B01D035/00
US Classification:
210/435000, 422/101000, 422/129000, 117/200000
Abstract:
The invention provides methods, apparatus, and systems for performing high-throughput preparation and screening of salts and polymorphs of drug candidates. The invention is directed towards enhancing the pre-formulation discovery process used for drug development. In particular, processes that determine suitable salts and processes that discover substantially every polymorph that can form from a particular drug candidate are provided. The processes are performed using several apparatuses that are specifically configured to carry-out various steps in a high-throughput characterization process. One such apparatus is configured for synthesizing a plurality of library members based on, for example, a library model generated by a computer system. Another apparatus may filter the synthesized solution to provide a substantially pure mixture that can be subjected to salt or polymorph testing. Yet another apparatus may be used to crystallize mixtures on a substrate such that the crystallized mixture can be screened by one or more screening devices.
