Container Monitoring Apparatus
First Claim
1. An apparatus to acoustically monitor a container, the apparatus comprising:
- a first acoustic transducer mountable to an exterior of the container to send a first acoustic signal into an interior of the container;
a second acoustic transducer mountable to the exterior of the container to send a second acoustic signal into the interior of the container; and
a data processing unit to process a first acoustic response signal related to the first acoustic signal and a second acoustic response signal related to the second acoustic signal to determine contents within the interior of the container at locations of the first acoustic transducer and the second acoustic transducer.

Abstract
An apparatus to acoustically monitor a container includes a first acoustic transducer mountable to an exterior of the container to send a first acoustic signal into an interior of the container and a second acoustic transducer mountable to the exterior of the container to send a second acoustic signal into the interior of the container. The apparatus further includes a data processing unit to process a first acoustic response signal related to the first acoustic signal and a second acoustic response signal related to the second acoustic signal to determine contents within the interior of the container at locations of the first acoustic transducer and the second acoustic transducer.

14. A method to acoustically monitor a container, the method comprising:
-
sending a first acoustic signal into an interior of the container with a first acoustic transducer; sending a second acoustic signal into the interior of the container with a second acoustic transducer; and receiving a first acoustic response signal related to the first acoustic signal; receiving a second acoustic response signal related to the second acoustic signal; and determining the contents within the interior of the container at the locations of the first acoustic transducer and the second acoustic transducer based upon the first acoustic response signal and the second acoustic response signal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
