US Patent:
6418783, Jul 16, 2002
Filed:
Feb 28, 2001
Appl. No.:
09/796877
Inventors:
Steven A. Sunshine - Pasadena CA
M. Gregory Steinthal - Los Angeles CA
Christopher K. Boehr - San Gabriel CA
Robert K. Nakayama - Los Angeles CA
Assignee:
Cyrano Sciences, Inc. - Pasadena CA
International Classification:
G01N 2700
US Classification:
73 2901, 73 103, 73 2334, 73 232, 702119, 702 24, 702 31
Abstract:
A vapor sensing device that is sufficiently small and lightweight to be handheld, and also modular so as to allow the device to be conveniently adapted for use in sensing the presence and concentration of a wide variety of specified vapors. The device provides these benefits using a sensor module that incorporates a sample chamber and a plurality of sensors located on a chip releasably carried within or adjacent to the sample chamber. Optionally, the sensor module can be configured to be releasably plugged into a receptacle formed in the device. Vapors are directed to pass through the sample chamber, whereupon the sensors provide a distinct combination of electrical signals in response to each. The sensors of the sensor module can take the form of chemically sensitive resistors having resistances that vary according to the identity and concentration of an adjacent vapor. These chemically sensitive resistors can each be connected in series with a reference resistor, between a reference voltage and ground, such that an analog signal is established for each chemically sensitive resistor.

US Patent:
7129095, Oct 31, 2006
Filed:
Mar 29, 2002
Appl. No.:
10/112151
Inventors:
Christopher Boehr - San Gabriel CA,
Shou-Hua Zhang - Arcadia CA,
Assignee:
Smiths Detection Inc. - Pasadena CA
International Classification:
G01N 27/416
US Classification:
436151, 436149, 436150, 422 8201, 422 8205, 422 83, 422 98, 702 22, 702 23, 702 24, 702 25, 702 30, 702 32
Abstract:
The present invention is related to the sensing of analytes and in particular, to methods of determining, resolving, identifying, or quantitating such analytes once detected. This invention provides systems and methods for identifying analytes, comprising using an importance index to give greater weight to the responses from sensors that measure characteristics most useful for identification of analytes. In other aspects, the systems and methods are useful for increasing the stability of electronic nose systems by prolonging the predictive capability of the training set of known analytes. In still other aspects, the systems and methods are useful for detecting and responding to events correlated with the presence of an analyte.

US Classification:
73 2901
Abstract:
A vapor sensing device that is sufficiently small and lightweight to be handheld, and also modular so as to allow the device to be conveniently adapted for use in sensing the presence and concentration of a wide variety of specified vapors as resulting from gases released during either decomposition and spoilage of food stuffs, or as released into either the breath or body fluids of a sick patient being medically diagnosed. The device provides these benefits using a sensor module that incorporates a sample chamber and a plurality of sensors located on a chip releasably carried within or adjacent to the sample chamber. Optionally, the sensor module can be configured to be releasably plugged into a receptacle formed in the device. Vapors are directed to pass through the sample chamber, whereupon the sensors provide a distinct combination of electrical signals in response to each. The sensors of the sensor module can take the form of chemically sensitive resistors having resistances that vary according to the identity and concentration of an adjacent vapor.
