  • Patent number: 11350845
    Abstract: Passive location of an emitter is achieved by sensing a signal propagated from the emitter at multiple sensing locations and determining its phase at each sensing location. A three-dimensional region is searched to find an emitter location for which phase estimates of the signal at the emitter location are in good agreement among the sensing locations. An iterative search from a set of starting points in the region may be performed. The region may be subdivided and each region searched in parallel using multiple processors in parallel. Phase at the sensing locations may be determined locally, using synchronized clocks at the sensing locations, or at a common receiver. In the latter case, signal propagation time from the sensing location to the receiver location is taken into account. The emitter may be a wireless endoscopy capsule, for example.

  • Patent number: 11166699
    Abstract: For estimating attenuation, diffraction effects are corrected by transmitting at different frequencies using apertures sized to match the on-axis intensity profile and/or resolution cell size between the transmissions where there is no attenuation. Attenuation causes a variance in return. A rate of change is estimated from a ratio of the magnitude of the signals or displacements responsive to the transmissions. The attenuation is calculated from the rate of change over depth of the ratio.
