Abstract: Systems and methods to achieve an auto-focus camera module having a precise bearing with low friction have been disclosed. Ball bearings are guiding a lens barrel. The balls of the ball bearings are running in guide slots and are held together by ball cages. Creeping of the balls is prevented by a positioning pin being deployed between a fixed part of a carrier of the camera module and a movable part of the lens barrel.

Abstract: Systems and methods to achieve an auto-focus camera module having a retention system with low friction have been disclosed. A magnetic retention system holds the carrier of the camera module, the ball bearings, and the movable lens barrel together. In case of a major mechanical shock the force of the magnetic retention system may not be sufficient to hold the parts together. Therefore a hook, which is deployed on a fixed part of the carrier of the camera module, is introduced in order to hold the parts together when a mechanical shock occurs. The hook does only engage in the movable lens barrel in a shock condition, the hook does not touch the lens barrel under normal operation conditions, hence not causing any friction if no shock occurs.

Abstract: Systems and methods are disclosed for cameras using ball bearings to guide the movements of movable parts as e.g. a lens barrel wherein the repulsive force of magnets is used to hold the ball bearings together an hence the movable parts in place in case of a mechanical shock. In a first embodiment of the invention the magnets and the ball bearings are on a same side of the lens barrel. In a second embodiment of the invention the magnets and the ball bearings are on an opposite side of the lens barrel. Furthermore a camera has been disclosed wherein the shutter is moved by a linear motor and an integrated circuit controls the motor moving the shutter and the actuators moving the lens barrel.

Abstract: Systems and methods for camera modules having a movable lens barrel, allowing a maximum lens diameter with minimal outside dimensions are disclosed. At least two actuators are moving the lens barrel. Each actuator is deployed in a separate corner of the camera module. In a first embodiment of the invention two actuators are deployed on a same side of the camera module having ball bearings between them. In a second embodiment two actuators are diagonally deployed having guiding rods deployed on the other corners of the camera module.

Abstract: The invention relates to an enclosure, particularly a housing for a mobile telephone, comprised of a first enclosure base body and of a second enclosure base body with a seal made of a sealing material. This seal is joined in a fixed manner to the first enclosure base body and sealingly rests against a second edge of the second enclosure base body. The seal is made of an elastically deformable sealing material. The invention also relates to a method for producing a housing part for a mobile telephone provided with an elastic seal according to the two-color injection molding method.
