Claim Text:
1. A system for estimating a volume of a content of a bin, the system comprising: at least three acoustic transceivers that are non-collinear; wherein a transmitter of an acoustic transceiver of the at least three acoustic transceivers is configured to transmit pulses of radiation towards an interior of the bin; wherein a receiver of at least one of the acoustic transceivers is configured to receive received echoes of the pulses of radiation; a fuzzy logic module arranged to apply a fuzzy logic algorithm for calculating, in response to the received echoes, confidence levels of origins of received echoes; wherein the received echoes are reflected or scattered from the origins; and a volume calculator that is arranged to calculate the volume of the content in response to (a) estimated locations of the origins, and (b) the confidence levels of the origins; and wherein the volume calculator is arranged to classify a received echo as a false echo when an origin of the receive echo is positioned outside the bin.
