  • Patent number: 12116267
    Abstract: A micro-electro-mechanical system (MEMS) device includes a mirror; at least one hinge; an electrostatic comb structure; and a control device. The control device causes, for a period of time, a voltage to be supplied to the electrostatic comb structure to cause the electrostatic comb structure to tilt the mirror about the at least one hinge in a particular direction. The control device causes, after the period of time and at an instant of time, the voltage to cease being supplied to the electrostatic comb structure. A tilt angle of the mirror, at the first instant of time, is less than a maximum tilt angle of the mirror in the particular direction. An angular momentum of the mirror, at the instant of time, is greater than zero kilogram meters squared per second in the particular direction.

  • Patent number: 12007555
    Abstract: A micro-electro-mechanical system (MEMS) device may comprise a first layer that includes a stator comb actuator; a second layer that includes a rotor comb actuator; a mirror structure that includes a mirror; and a first set of hinges and a second set of hinges configured to tilt the mirror structure about a first axis of the MEMS device based on a driving torque caused by the stator comb actuator engaging with the rotor comb actuator. The first set of hinges may be configured to resist a lateral linear force on the mirror structure in a direction associated with the first axis caused by the stator comb actuator engaging with the rotor comb actuator. The second set of hinges may be configured to resist an in-plane torque on the mirror structure about a second axis of the MEMS device caused by the stator comb actuator engaging with the rotor comb actuator.
