Abstract: MEMS devices include a suspended element connected to a fixed part of a substrate by one or more flexures, wherein the one or more flexures are configured to permit movement of the suspended element relative to a fixed part of the substrate. A sensor coupled to the suspended element and a damping structure coupled to the suspended element extends into a gap between the suspended element and the fixed part of the substrate. One or more fluid confinement structures are configured to permit movement of the damping structure within a limited portion of the gap and to confine a viscoelastic fluid to the limited portion of the gap.

Abstract: In some embodiments, a LIDAR system may include at least one processor configured to control at least one light source for projecting light toward a field of view and receive from at least one first sensor first signals associated with light projected by the at least one light source and reflected from an object in the field of view, wherein the light impinging on the at least one first sensor is in a form of a light spot having an outer boundary. The processor may further be configured to receive from at least one second sensor second signals associated with light noise, wherein the at least one second sensor is located outside the outer boundary; determine, based on the second signals received from the at least one second sensor, an indicator of a magnitude of the light noise; and determine, based on the indicator the first signals received from the at least one first sensor and, a distance to the object.

Abstract: An image display apparatus includes a light source device including a light source unit; a scanning optical system including an image forming unit on which an intermediate image is formed by light from the light source unit; and a virtual image optical system configured to guide light of the intermediate image by using a reflecting mirror and a curved transmissive reflection member. The scanning optical system includes an optical scanning unit configured to scan the light from the light source unit in a main scanning direction and a sub-scanning direction of the image forming unit. The image forming unit is a transmissive member curved with a convex surface toward the reflecting mirror.

Abstract: A MEMS based alignment technology based on mounting an optical component on a released micromechanical lever configuration that uses multiple flexures rather than a single spring. The optical component may be a lens. The use of multiple flexures may reduce coupling between lens rotation and lens translation, and reduce effects of lever handle warping on lens position. The device can be optimized for various geometries.

Abstract translation: 基于MEMS的对准技术，其基于将光学部件安装在使用多个挠曲而不是单个弹簧的释放的微机械杆配置上。 光学部件可以是透镜。 使用多个弯曲可能会减少透镜旋转和透镜平移之间的耦合，并减少杠杆手柄翘曲对透镜位置的影响。 该设备可以针对各种几何形状进行优化。

Abstract: An optical device includes an elastic support portion which includes a torsion bar which extends along a second direction perpendicular to a first direction and a nonlinearity relaxation spring which is connected between the torsion bar and a movable portion. The nonlinearity relaxation spring is configured so that a deformation amount of the nonlinearity relaxation spring around the second direction is smaller than a deformation amount of the torsion bar around the second direction and a deformation amount of the nonlinearity relaxation spring in a third direction perpendicular to the first direction and the second direction is larger than a deformation amount of the torsion bar in the third direction while the movable portion moves in the first direction. A comb electrode is disposed along an outer edge of the movable portion.

Abstract: A scanning device includes a substrate, which is etched to define an array of two or more parallel rotating members and a gimbal surrounding the rotating members. First hinges connect the gimbal to the substrate and defining a first axis of rotation, about which the gimbal rotates relative to the substrate. Second hinges connect the rotating members to the support and defining respective second, mutually-parallel axes of rotation of the rotating members relative to the support, which are not parallel to the first axis.
