Filed:

Oct 30, 2006

Appl. No.:

11/589434

Inventors:

Edward M Godshalk - Newberg OR, US
Timothy Raynolds - Woodstock VT, US
Paul M. Meaney - Hanover NH, US
Keith D. Paulsen - Hanover NH, US
Greg Burke - W. Canaan NH, US

Assignee:

Microwave Imaging Systems Technologies, Inc. - Hanover NH

International Classification:

H05B 6/64
A61B 5/05

US Classification:

219679, 600430

Abstract:

A non-invasive microwave analysis system determines scattered phase and/or amplitude data for a liquid in a container. A tank holds coupling liquid; the system includes a membrane for separating the liquid container from the coupling liquid. A transmitter antenna situated within the coupling liquid transmits microwaves. One or more receiver antennas within the coupling liquid convert microwave radiation that scatters from the liquid in the container into microwave electronic signals. Electronics process the microwave electronic signals to determine scattered phase and/or amplitude values of the microwave radiation.

US Classification:

219679, 600430

Abstract:

A non-invasive microwave analysis method determines scattered phase and/or amplitude data for a liquid in a container. A transmitter antenna transmits microwaves that scatter from the container and the liquid in the container. One or more receiver antennas convert the microwaves into microwave electronic signals that are processed to determine the scattered phase and/or amplitude data. Another non-invasive microwave screening method includes placing a container of an unknown liquid in a tank. The container is separated by a membrane from coupling liquid in the tank. Microwave radiation transmits from a transmitter antenna and scatters from the container and the unknown liquid. One or more receiver antennas convert the microwave radiation into microwave electronic signals. The microwave electronic signals are processed to determine scattered phase and/or amplitude data. A pass result or a fail result is determined based on the scattered phase and/or amplitude data.

International Classification:

A61B005/05

US Classification:

600430000

Abstract:

Non-invasive microwave analysis systems and methods determine scattered phase data for a liquid in a container. A transmitter antenna situated within coupling liquid separated from the container by a flexible membrane transmits microwaves that scatter from the container and the liquid in the container. One or more receiver antennas within the coupling liquid convert the microwaves into microwave electronic signals that are processed to determine the scattered phase data. Non-invasive microwave analysis systems and methods image a portion of a biological subject. A transmitter antenna situated within coupling liquid separated from the subject by a flexible membrane transmits microwaves that scatter from the container and the subject. One or more receiver antennas within the coupling liquid convert the microwaves into microwave electronic signals that are processed to reconstruct a cross-sectional image of the subject.

Robin Augustine - Uppsala, SE

Assignee:

Trustees of Dartmouth College - Hanover NH

International Classification:

A61B 5/00
A61B 18/18

Abstract:

Embodiments of the present disclosure pertain to transmission dielectric probes with at least one channel that extends across the probe. The channel includes a first opening on a first side of the transmission dielectric probe, and a second opening on a second side of the transmission dielectric probe. The first opening and the second opening are on opposite ends of the transmission dielectric probe, and the second opening is associated with an outer surface of the transmission dielectric probe. Additionally, the first opening and the second opening have different diameters, different geometries, or combinations thereof. Further embodiments pertain to methods of operating the transmission dielectric probes by placing the outer surface of the transmission dielectric probe on a surface of an object, transmitting a signal from a first channel through the surface and into the object, and receiving the transmitted signal back through a second channel.

Abstract:

A system for dielectric testing of wine in a bottle includes (a) a coaxial probe for interrogating the wine, wherein the coaxial probe has an open end for contacting an exterior surface of the bottle, and (b) a measurement module for determining a dielectric property associated with the wine by generating and measuring radio waves propagating through the coaxial cable. A method for dielectric testing of wine in a bottle includes measuring a radio-wave reflection signal associated with the wine by interrogating the wine, through the bottle, with radio waves, and determining a dielectric property associated with the wine from the radio-wave reflection signal. A probe for radio-wave interrogation of wine in a bottle has an inner conductor, an outer conductor, and an open end with curvature matching the curvature of an exterior surface of the bottle.
