Abstract: A MEMS gyroscope has a structure with a main extension in a horizontal plane formed by first and second horizontal axes. The gyroscope includes a first driving mass that performs a translation driving movement along the second horizontal axis of the horizontal plane, and a first sensing mass, having an anchoring element arranged centrally with respect to the first sensing mass and connected to the anchoring element by an elastic arrangement. The first sensing mass is coupled to the first driving mass by an elastic coupling element and performs a rotation movement in the horizontal plane around the anchoring element, dragged by the first driving mass, and a sensing movement of rotation outside the horizontal plane around a rotation axis defined by the elastic arrangement, in response to an angular velocity around the first horizontal axis. The rotation axis extends along the second horizontal axis, parallel to the driving movement.

Abstract: Packaged MEMS device having a MEMS die of semiconductor material formed by a sensor body and a cap mutually bonded. The sensor body incorporates at least one MEMS component and the cap carries a humidity sensor having a first and a second group of electrodes, facing each other and capacitively coupled, configured to provide a humidity signal. A packaging mass, of electrically insulating material, surrounds the MEMS die and the humidity sensor.

Abstract: A microelectromechanical structure has a mobile-mass with a main extension in a horizontal plane, defined by first and second horizontal axes, and having an internal window. The mobile-mass is elastically coupled to a central anchoring structure, arranged centrally with respect to the window, by an elastic structure, so that it can perform a first rotation outside the horizontal plane and a second rotation in the horizontal plane. The elastic structure has a first symmetry-axis parallel to the first horizontal-axis and a second symmetry-axis parallel to the second horizontal-axis, and has first and second elastic elements arranged in a central position of the window, on opposite sides with respect to the first symmetry-axis. The first and second elastic elements have the shape of an “H” in the horizontal plane, mirrored with respect to the first symmetry-axis and face each other at a separation distance along the second horizontal-axis.

Abstract: A microelectromechanical gyroscope includes a die of semiconductor material forming a substrate and a detection structure suspended over the substrate. The detection structure has a main extension in a horizontal plane, is symmetrical with respect to a central axis of symmetry, and is provided, for each gyroscope detection axis, with: a first pair of detection masses arranged on a first side of the central axis of symmetry; and a second pair of detection masses arranged on a second side of the central axis of symmetry, opposite to the first side in the horizontal plane. The detection masses of each pair are capacitively coupled to respective stator electrodes according to a differential detection scheme. The stator electrodes are arranged symmetrically with respect to one another on opposite sides of the central axis of symmetry.

Abstract: Microelectromechanical device comprising a supporting body, containing semiconductor material and a movable mass, constrained to the supporting body with a relative degree of freedom with respect to at least one motion direction, within a range of admissible positions. The device also comprises stopper elements, operable by the movable mass due to movements along the at least one motion direction and configured to apply stop forces to opposite sides of the movable mass, transversely to the at least one motion direction, when the movable mass reaches a respective endpoint of the range of admissible positions, so as to prevent the movable mass from exceeding the respective endpoint.

Abstract: A surface-consistent refraction analysis method to automatically derive near surface corrections for seismic data processing. The method uses concepts from surface-consistent analysis applied to refracted arrivals. The method includes the use of CMP-offset-azimuth binning, evaluation of mean travel time and standard deviation for each bin, rejection of anomalous first break (FB) picks, derivation of CMP-based travel time-offset functions, conversion to velocity-depth functions, evaluation of long wavelength statics and calculation of surface-consistent residual statics through waveform cross-correlation. Residual time lags are evaluated in multiple CMP-offset-azimuth bins by similarity analysis with a pilot trace for all the other traces in the gather where the correlation window is centered at the refracted arrival. The similarity analysis may take the form of computerized cross-correlation, or other criteria such as semblance.
