MICROMECHANICAL RESONATOR ASSEMBLY WITH EXTERNAL ACTUATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18196737 titled 'MICROMECHANICAL RESONATOR ASSEMBLY WITH EXTERNAL ACTUATOR

Simplified Explanation

The patent application describes a micromechanical resonator assembly with an internal actuator and an external actuator.

  • The internal actuator has an oscillation body that can oscillate about one or more axes and has eigen frequencies.
  • The assembly also includes an external actuator with an oscillating part.
  • There is a mounting base with an electronic driving part.
  • The external actuator is mounted on the mounting base and connected to the electronic driving part.
  • This allows the external actuator to transfer energy to the oscillation body of the internal actuator, causing it to oscillate.
  • The innovation of this assembly is that it provides a way to externally actuate the oscillation body of the internal actuator.
  • This external actuation enables the assembly to achieve very large scan angles of 180°.


Original Abstract Submitted

A micromechanical resonator assembly which includes an internal actuator. The internal actuator further includes an oscillation body configured to oscillate about one or more axes, the oscillation body having one or more eigen frequencies. The micromechanical resonator assembly further includes an external actuator that includes an oscillating part. The micromechanical resonator assembly further includes a mounting base that includes electronic driving part. The external actuator being mounted on the mounting base and being electrically connected to the electronic driving part, for allowing excitation of the oscillation body of the internal actuator by transfer of energy from the oscillating part to the oscillating body. The micromechanical resonator assembly provides external actuation of the oscillation body of the internal actuator by use of the external actuator and hence, provides extremely large scan angles of 180°.
