  • Automated generation of digital elevation models
    Patent number: 10339707
    Abstract: Digital elevation models are generated based on multiple sets of elevation measurements. For example, multiple sets of elevation measurements are merged to create a combined set of elevation measurements by using different merging methods, based on the resolutions of the sets within a given physical landscape. An elevation model can then be generated based on the combined set of elevation measurements by using multiple estimation processes in combination to generate estimated elevations and uncertainty values for various areas of the given physical landscape.

  • Hydrophone calibration system
    Patent number: 9746585
    Abstract: Calibration apparatus including a pressure cap and a pressure base that define a pressure chamber that is fillable with a liquid. A reference sensor and a sensor under test are exposed to acoustic pressures in the liquid, and responses measured. The sensor under test is secured through one of the pressure cap or base, and responses measured at acoustic frequencies as low as 0.001 Hz and at hydrostatic pressures of at least 5000 psi.
