Publication number: 20240040218Abstract: Various magnetic camera brake embodiments are disclosed. According to some embodiments, the magnetic camera brakes leverage a magnetic attraction (or repulsion) force between an iron and magnetic body to hold the moving camera components at a desired focus position—even under high amplitude acceleration loads. When high disturbance rejection is desired, the magnet attracts the camera to the desired focus position (e.g., an infinity focus position) with enough force to overcome approximately 10 g's of external acceleration. In some embodiments, ball bearings may be used to provide constraints in up to 5 degrees of freedom (e.g., all but z-axial translation along the optical axis), so there is no rocking of the image sensor (or lens barrel). When “macro” photos are desired of subjects closer than the hyperfocal distance, an actuator mechanism may be configured to pull the image sensor out of the desired focus position and into the macro focus region.Type: ApplicationFiled: July 28, 2023Publication date: February 1, 2024Inventors: Zachary W.

Patent number: 11831969Abstract: Small form factor cameras that may include one or more voice coil motor actuators, one or more springs and/or one or more motion damping mechanisms. Multiple cameras or camera modules may be positioned close together within a device. Multiple camera modules may be placed closely adjacent to one another by utilizing a recessed portion of the respective perimeters, such as by having one corner removed from rectangular perimeters. By aligning two such recessed portions two camera modules may be more placed more closely together, thereby reducing the distance between the apertures of the respective camera modules. Within asymmetric camera modules, individual components, such as magnets, coils, damping pins, gel pockets, etc., may be asymmetrically placed to correspond with, or in response to the reduced space resulting from the asymmetry of the camera module outline.Type: GrantFiled: January 27, 2022Date of Patent: November 28, 2023Assignee: Apple Inc.Inventors: Alfred N. Mireault, Andrew S. Jozefov, Zachary W. Birnbaum, Scott W. Miller

Patent number: 11681158Abstract: A damper arrangement may be used in a camera module that includes a first (e.g., stationary) and a second (e.g., dynamic) component. The second component may hold a lens such that the lens moves together with the second component. The damper arrangement may include an interface member that extends from the first or the second component to at least partially into a viscoelastic material within a volumetric space configured in the first component, the second component, or both. The interface member may include a mounting portion having a thickness and a viscoelastic material section, having a different thickness, that interacts with viscoelastic material to dampen motion of the second component, for example, during operation of a lens actuator to move the second component along an optical axis of the lens. The interface member may be a two-piece interface member, such as a pin soldered into a hole in a plate, for example.Type: GrantFiled: September 10, 2021Date of Patent: June 20, 2023Assignee: Apple Inc.Inventors: Scott W.

Patent number: 11573393Abstract: Various embodiments include a camera having one or more base cutouts for a position sensing arrangement. For example, the position sensing arrangement may be used to determine a position of a moveable lens group and/or a moveable image sensor. According to some embodiments, a base structure of the camera may include a cutout that allows for a protrusion of a lens carrier to extend (e.g., in a direction parallel to an optical axis of the camera) past at least a portion of the base structure. A probe magnet may be attached to the protrusion of the lens carrier, and a position sensor for sensing magnetic fields of the probe magnet may be attached to the substrate.Type: GrantFiled: April 29, 2021Date of Patent: February 7, 2023Assignee: Apple Inc.Inventors: Zachary W.

Patent number: 11019266Abstract: A suspension spring may suspend an optical component for a camera or other device that implements the optical component to focus light being captured by an image sensor. The suspension spring may move along with the optical component that it suspends as a result of manual or automated focus changes that change the position of the optical component along an optical axis. The suspension spring may make contact with surfaces of other components or materials in the cameras or other systems. Those surfaces of the suspension spring that can make contact may be blunted to prevent the generation of loose particles that can interfere with the image sensor.Type: GrantFiled: August 23, 2019Date of Patent: May 25, 2021Assignee: Apple Inc.Inventors: Zachary W.
