Movable system for measuring a content of a bin
First Claim
1. A method for evaluating a content of a bin, the method comprising:
- receiving, from a first acoustic detection device that comprises a first acoustic transceiver array and by a computer, multiple first estimates of different first areas of an upper surface of the content, the first estimates are calculated by the first acoustic detection device by processing first echoes of acoustic pulses;
wherein the first acoustic transceiver array comprises transducers;
wherein each first acoustic pulse has a shape of a lobe that is more than forty degrees wide;
wherein the first echoes are received by the first acoustic transceiver array as a result of a transmitting of the acoustic pulses by the first acoustic transceiver array towards the different first areas of the upper surface of the content when the first acoustic transceiver array was positioned at different locations;
wherein the first acoustic transceiver array is connected to a movable apparatus that moves the first acoustic transceiver array between the different locations of the first acoustic transceiver array;
receiving, by the computer and from an acoustic based location device, first location information indicative of the different locations of the first acoustic transceiver array;
generating, by the computer, an estimate related to the content in response to the multiple first estimates and to the first location information;
transmitting by the first acoustic transceiver array and by a second acoustic transceiver array, a plurality of acoustics pulses in an at least a partially overlapping manner towards an overlap area to generate an acoustic interference pattern that comprises multiple fringes;
wherein the second acoustic transceiver array comprises transducers;
detecting by at least one of the first and second acoustic transceiver arrays a fringe of the acoustic interference pattern and providing a fringe detection signal; and
wherein a distance between the first and second acoustic transceiver arrays 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.

Abstract
A method and a system for evaluating a content of a bin, the method may include (a) transmit multiple acoustic pulses by multiple acoustic transceiver arrays towards different areas of an upper surface of the content when the acoustic transceivers are positioned at different locations; wherein the multiple acoustic transceiver arrays are connected to a device that is moved according to a movement pattern between the different locations; receive by the multiple acoustic transceiver arrays multiple echoes of the multiple acoustic pulses; process by the multiple acoustic transceiver arrays the multiple echoes to provide multiple estimates of the different areas; associate with the multiple estimates of the different areas timing information indicative of a timing of the receiving of the multiple echoes to a computer; and obtain by an acoustic based location device, location information readings related to locations of the device at multiple points of time.
