Sonia Constantini has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • MEMS device with piezoelectric actuation, a projective MEMS system including the MEMS device and related control method
    Patent number: 10310253
    Abstract: A MEMS device includes a fixed structure and suspended structure including an internal structure and a first arm and a second arm. Each arm has a first end fixed to the fixed structure and a second end fixed to the internal structure. The ends are angularly arranged at a distance apart. Piezoelectric actuators mounted to the arms are driven so as to cause deformation of the arm and produce a rotation of the internal structure. In a resting condition, each of the first and second arms has a respective elongated portion with a respective concavity. The internal structure extends in part within the concavities of the elongated portions of the first and second arms.

  • Mirror micromechanical structure and related manufacturing process
    Patent number: 10288874
    Abstract: A mirror micromechanical structure has a mobile mass carrying a mirror element. The mass is drivable in rotation for reflecting an incident light beam with a desired angular range. The mobile mass is suspended above a cavity obtained in a supporting body. The cavity is shaped so that the supporting body does not hinder the reflected light beam within the desired angular range. In particular, the cavity extends as far as a first side edge wall of the supporting body of the mirror micromechanical structure. The cavity is open towards, and in communication with, the outside of the mirror micromechanical structure at the first side edge wall.

    Abstract: A mirror micromechanical structure has a mobile mass carrying a mirror element. The mass is drivable in rotation for reflecting an incident light beam with a desired angular range. The mobile mass is suspended above a cavity obtained in a supporting body. The cavity is shaped so that the supporting body does not hinder the reflected light beam within the desired angular range. In particular, the cavity extends as far as a first side edge wall of the supporting body of the mirror micromechanical structure. The cavity is open towards, and in communication with, the outside of the mirror micromechanical structure at the first side edge wall.
