Abstract: A ball bearing sensor shift arrangement for a camera may include one or more voice coil motor (VCM) actuators that include the fixed magnets, optical image stabilization (OIS) coils, and/or one or more autofocus (AF) coils. The ball bearing sensor shift arrangement may be coupled with an image sensor of the camera, and may include carrier frames configured to move on ball bearings so as to enable motion of the image sensor in multiple degrees-of-freedom (DOF). An OIS carrier frame(s) may be coupled with the OIS coils, which may be positioned proximate the fixed magnets and used for moving the image sensor in directions orthogonal to an optical axis of the camera. An AF carrier frame may be coupled with the AF coil(s), which may be positioned proximate the fixed magnets and used for moving the image sensor in at least one direction parallel 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: A camera may use one or more actuators to implement various functions. An actuator of a camera may include one or more coil structures. The coil structure may include at least one layer of coil at a first side of a dielectric layer, and at least another one layer of coil at a second side of the dielectric layer opposite the first side. The coils at the two sides of the dielectric layers may have different numbers of turns. In particular, a section of the coil at the second side of the dielectric layer may be left out to cause the different numbers of turns between the coils at the two sides. The coil structure may also include one or more connection pads at the second side of the dielectric layer.

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.
