Abstract

A system and method for characterizing non-solid substances, the system comprising a housing body having a cavity therein the cavity is configured to contain said substances; a transmit/receive unit configured to generate and transmit Radio Frequency (RF) signals; at least one electromagnetic sensor attached to said housing body and said transmit/receive unit, wherein said sensor is configured to provide RF responses data of said substances; a Radio Frequency Signals Measurement Unit (RFSMU) configured to receive said RF responses and measure said RF responses; and a processor connected to said sensor said processor is configured to process said responses to identify the characteristics of said substances.

First claim

What is claimed is:

1 . A system for characterizing substances, said system comprising:
a housing body having a cavity therein wherein said cavity is configured to contain said substances; a transmit unit configured to transmit a plurality of Radio Frequency (RF) signals; at least one electromagnetic sensor in communication with said transmit unit, wherein said at least one electromagnetic sensor is configured to provide RF responses data of said substances; a Radio Frequency Signals Measurement Unit (RFSMU) configured to receive said RF responses and measure said RF responses; and a processor connected to said sensor said processor is configured to process said responses to identify the characteristics of said substances, wherein said housing body comprises a granular material configured to receive said substance.

2 . The system of claim 1 wherein said sensor comprises at least two antennas and wherein said processor is configured to analyze a passage of energy transmitted from at least one of said antennas to at least one other antenna.

3 . The system of claim 1 wherein said sensor is a capacitive sensor and wherein said sensor is configured to spatially resolve the dielectric properties of the substances.

4 . The system of claim 3 wherein said capacitive sensor comprises:
a plurality of sensing feed lines;
a plurality of sensing plates; and
a plurality of receive lines wherein each of said plurality of feed lines is coupled to at least one corresponding receive line through an electromagnetic field formed between at least two sensing plates connected to said feed and receive lines and the substances.

5 . The system of claim 1 wherein said sensor is selected from the group consisting of: an antenna array, a MIMO radar sensor, resonant cavity sensor, microwave sensor, waveguide sensor.

6 . The system of claim 5 wherein said MIMO radar sensor comprises a wideband antenna array connected to the transmit unit, said transmit unit is configured to generate microwave signals to said antenna array.

7 . The system of claim 1 wherein said RF responses data comprises impedance measurements.

8 . The system of claim 1 wherein said tube comprises an inlet pipe and outlet pipe.

9 . The system of claim 1 wherein said sensor is attached externally to the housing body walls.

10 . The system of claim 1 wherein said sensor is attached internally to the housing body.

11 . The system of claim 1 wherein said substances are selected from the group consisting of:
liquid, paste, gas.

12 . The system of claim 11 wherein said liquid is selected from the group consisting of:
oil, milk, ink, water, bodily fluids.

13 . The system of claim 1 wherein said sensor in not in direct contact with said substance.

14 . A method for characterizing substances, said method comprising:
obtaining multiple Radio Frequency (RF) signals from one or more RF sensors, said RF sensors are attached to a housing body or to a cavity of said housing body wherein said cavity comprises a granular material configured to receive said substances; measuring the obtained RF signals by a Radio Frequency Signal Measurement Unit (RFSMU), wherein said RFSMU is connected to said sensors; and processing said measured RF signals by a processor to identify the characteristics of said substances.

15 . The method of claim 14 comprising processing the obtained multiple RF signals to measure the dielectric properties of said substances.

16 . The method of claim 15 comprising:
comparing the dielectric properties of said substances to a predefined threshold reference to identify abnormal characteristics in said substances.

17 . The method of claim 16 wherein the properties of the substances are spatially resolved.

18 . The method of claim 14 wherein said substances are selected from the group consisting of: liquid, paste, gas.

19 . The method of claim 18 wherein said liquid is selected from the group comprising: oil, milk, ink, water, bodily fluids.

20 . The method according to claim 19 comprising processing the dielectric properties to detect mastitis infection in the milk.
