  • Patent number: 10317649
    Abstract: A camera module includes an optical package, a camera actuator for moving the optical package, a camera subassembly, and one or more resilient members arranged within the camera subassembly to prevent, reduce, or cushion contact between the optical package and other components of the camera. The resilient members may be mounted on the lens carrier of the optical package and configured to come into resistive contact with components of the camera subassembly and/or mounted on components of the camera subassembly and configured to come into resistive contact with the optical package. In either case, the resistive cushioning provided by the resilient members may reduce or prevent contact (and an associated rattling noise associated with the contact) between the optical package and the hard components of the camera subassembly. The resilient members may be configured to cushion, but also allow hard stop contact. In embodiments bumpers (e.g., elastomeric pads) may be used.

  • Publication number: 20150146312
    Abstract: A microelectromechanical systems (MEMS) device may be provided with one or more sintered electrical contacts. The MEMS device may be a MEMS actuator or a MEMS sensor. The sintered electrical contacts may be silver-paste metalized electrical contacts. The sintered electrical contacts may be formed by depositing a sintering material such as a metal paste, a metal preform, a metal ink, or a metal powder on a wafer of released MEMS devices and heating the wafer so that the deposited sintering material diffuses into a substrate of the device, thereby making electrical contact with the device. The deposited sintering material may break through an insulating layer on the substrate during the sintering process. The MEMS device may be a multiple degree of freedom actuator having first and second MEMS actuators that facilitate autofocus, zoom, and optical image stabilization for a camera.

  • Patent number: 9039208
    Abstract: The invention provides, in some aspects, devices for image acquisition that use seals between concentrically disposed portions of an enclosure and an optics assembly in order to protect image acquisition components from the surrounding environment while providing adequate friction for both adjusting and locking focus. Such devices can include an image capture medium that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal is disposed between, and in contact with, the optics assembly and the enclosure. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing contamination from the environment from entering into the enclosure.
