1. A method for evaluating a content of a bin, the method comprising:
- transmitting at a first point in time and by a first acoustic transceiver array, a first acoustic pulse;
wherein the first acoustic transceiver array comprises transducers;
receiving by a second acoustic transceiver array an echo of the first acoustic pulse;
wherein the second acoustic transceiver array comprises transducers; and
processing the echo of the first acoustic pulse to assist in a provision of a first estimate related to the content;
wherein the second acoustic transceiver array differs from the first acoustic transceiver array; and
wherein a distance between the first and second acoustic transceiver array is (a) at least ten times a distance between centers of the transducers of the second acoustic transceiver array; and
(b) at least ten times a distance between centers of the transducers of the first acoustic transceiver array.

11. A system for evaluating a content of a bin, the system comprises:
-
a first acoustic transceiver array that is arranged to transmit at a first point in time a first acoustic pulse towards an expected location of the content wherein the first acoustic transceiver array comprises transducers; a second acoustic transceiver array that is arranged to receive an echo of the first acoustic pulse;
wherein the second acoustic transceiver array comprises transducers;wherein the second acoustic transceiver array differs from the first acoustic transceiver array; wherein a distance between the first and second acoustic transceiver array is (a) at least ten times a distance between centers of the transducers of the second acoustic transceiver array; and
(b) at least ten times a distance between centers of the transducers of the first acoustic transceiver array, andwherein the second acoustic transceiver array is arranged to process the echo of the first acoustic pulse to assist in a provision of a first estimate related to the content. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
