International Classification:

A61B 5/097

US Classification:

600532

Abstract:

An upper respiratory bacterial infection is detected from exhaled mammalian breath by using a colorimetric sensor array having a spectral response characteristic that changes when exposed to bacteria-produced analytes in the exhaled breath. A flow regulating system directs a leading portion of the exhaled breath into gaseous communication with the array to change its spectral response characteristic, and discharges a trailing portion of the exhaled breath exteriorly of the apparatus. A spectral analysis system analyzes the spectral response characteristic changed solely by the leading portion of the exhaled breath, and detects the upper respiratory bacterial infection when the bacteria-produced analytes are present therein. Reactivity of the analytes with the array is increased by advance oxidizing and/or heating the analytes.

International Classification:

C12Q 1/18
G01N 33/52

Abstract:

Devices, systems, and methods for species and/or strain specific identification and assessment of susceptibility of microorganisms based on the response of sensors in a colorimetric sensor array to metabolic products of the microorganism. An exemplary method according to an embodiment of the present disclosure can include culturing a sample that contains microorganisms. The sample can be in a medium which is exposed to a colorimetric sensor array. A test substance can be introduced to the sample. The method can assess a susceptibility of the microorganisms to the test substance based on a change in at least one sensor in the colorimetric sensor array. Sensors in the colorimetric sensor array can change in response to volatile organic compounds produced by the microorganisms after addition of the test sub stance.

International Classification:

B60C 11/24
C08K 3/04
B60C 11/00
B60C 23/04

Abstract:

This disclosure provides a tire formed of a body having multiple plies and a tread that surrounds the body. In some implementations, the plies and/or the tread include a resonator that generates a resonant signal in response to being activated by locally generated power or by an externally generated excitation signal. Multiple resonators formed of carbon-containing materials are distributed in the plies and/or tread to respond to changes to the tire by altering a characteristic of the resonant signal. Such alterations include frequency shifting of the resonant signal and/or attenuation of the resonant signal. The resonator can be configured to resonate at a first frequency when a structural characteristic of a respective ply or tread is greater than a level, and to resonate at a second frequency different than the first frequency when the structural characteristic of the respective ply or tread is not greater than the level.

Assignee:

Lyten, Inc. - Sunnyvale CA

International Classification:

G01N 27/414
C01B 32/182
B01J 20/28

Abstract:

This disclosure provides a sensor for detecting an analyte. The sensor can include an antenna and sensing material both disposed on a substrate, where the sensing is electrically coupled to the antenna. The sensing material can include a carbon structure including a multi-modal distribution of pore sizes that define a surface area including bonding sites configured to interact with one or more additives and the analyte. The carbon structure is configured to generate a resonant signal indicative of one or more characteristics of the analyte in response to an electromagnetic signal. The carbon structure can include distinctly sized interconnected channels defined by the surface area and configured to be infiltrated by the analyte, and exposed surfaces configured to adsorb the analyte. Each of the interconnected channels can include microporous pathways and/or mesoporous pathways, which can increase a responsiveness of the sensing material proportionate to the analyte within the carbon structure.
