Abstract: Passive dampers (e.g., a viscoelastic material such as a silicon gel) may be applied at one or more locations within an actuator module between a moving component (an optics assembly) and a fixed component (e.g., a cover attached to a base). The passive dampers act to passively dampen the motion of the optics assembly on the XY plane within the actuator module during optical image stabilization (OIS) of the optics assembly when subjected to external excitation or disturbance, and may also provide Z (optical) axis damping and impact protection. Process control and automation manufacturing and assembly methods for an OIS voice coil motor (VCM) actuator module including passive dampers are described, as well as design elements that provide for the integrity and reliability of the passive dampers over the life cycle of the actuator module.

Abstract: A camera system includes a first camera unit and a second camera unit. The first camera unit may include a first actuator. The second camera unit may include a second actuator. The first actuator may move one or more components of the first camera unit to provide autofocus and/or optical image stabilization functionality to the first camera unit. The second actuator may move one or more components of the second camera unit to provide autofocus and/or optical image stabilization functionality to the second camera unit. The first camera unit may be configured to capture a first image of a first visual field. The second camera unit may be configured to capture, simultaneously with the first camera unit capturing the first image, a second image of a second visual field.

Abstract: A camera may use a multi-axis image sensor shifting system to implement both autofocus (AF) and optical image stabilization (OSI) functions. The multi-axis image sensor shifting system may include a flexure suspension arrangement and an actuator. The flexure suspension arrangement may include an inner frame, an intermediate frame, and an outer frame. The actuator may include one or more magnets, and two sets of one or more coils attached respectively to some of the frames of the flexure suspension arrangement. Current flowing through the coils may be regulated to interact with the magnetic field of the magnets to generate motive force to move an image sensor of the camera relative to a lens group in multiple directions.

Abstract: In some embodiments, a camera actuator includes an actuator base, an autofocus voice coil motor, and an optical image stabilization voice coil motor. In some embodiments, the autofocus voice coil motor includes a lens carrier mounting attachment moveably mounted to the actuator base, a plurality of shared magnets mounted to the base, and an autofocus coil fixedly mounted to the lens carrier mounting attachment for producing forces for moving a lens carrier in a direction of an optical axis of one or more lenses of the lens carrier. In some embodiments, the optical image stabilization voice coil motor includes an image sensor carrier moveably mounted to the actuator base, and optical image stabilization coils moveably mounted to the image sensor carrier within the magnetic fields of the shared magnets, for producing forces for moving the image sensor carrier in a plurality of directions orthogonal to the optical axis.

Abstract: Various embodiments include a damper arrangement that may be used to dampen motions of a dynamic component. In some embodiments, the damper arrangement may be used in a camera module that includes a stationary component and a dynamic component. For instance, the dynamic component may hold a lens such that the lens moves together with the dynamic component. In various examples, the damper arrangement may include an interface member that extends from the stationary component or the dynamic component to at least partially into a viscoelastic material within a pocket configured in the stationary component, the dynamic component, or both. The interface member may be configured to traverse within the viscoelastic material to dampen motion of the dynamic component, for example, during operation of a lens actuator to move the dynamic component along an optical axis of the lens.

Abstract: Various embodiments include an interlock arrangement that may be used to attach a lens barrel to a lens carrier of a camera. In some embodiments, the interlock arrangement may restrict movement of the lens barrel relative to the lens carrier along at least an optical axis. In various examples, the interlock arrangement may include one or more grooves and one or more protrusions. For instance, a groove may be defined by the lens barrel or the lens carrier, and a protrusion may extend from the lens barrel or the lens carrier to at least partially into the groove. In some cases, the interlock arrangement may include an adhesive that at least partially fills gaps within the interlock arrangement between the lens barrel and the lens carrier. According to some embodiments, the interlock arrangement may include one or more recesses that provide inlets for the adhesive to be introduced to the gaps within the interlock arrangement.
