摘要:
A method and a system for evaluating a content of a bin, the method may include: transmitting by multiple acoustic transceiver arrays, a plurality of acoustics pulses in an at least partially overlapping manner towards an expected location of the content to generate an acoustic interference pattern that comprises multiple fringes; detecting by an acoustic transceiver array a first fringe of the acoustic interference pattern and providing a fringe detection signal; and processing the first fringe detection signal to assist in a provision of a first estimate related to the content. A distance between a pair of acoustic transceiver arrays is at least ten times a distance between transducers of a same acoustic transceiver array.

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.

A method and a system for evaluating a content of a bin, the method may include: transmitting at a first point in time and by a first acoustic transceiver array, a first acoustic pulse; receiving by a second acoustic transceiver array an echo of the first acoustic pulse; 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 transceiver array; wherein a distance between the first and second acoustic transceiver array is at least ten times a distance between transducers of the second acoustic transceiver array.
