RELATED APPLICATION

[0001] Incorporated herein by reference, in its entirety, is PCT/US2017/021915 (published as WO 2017/156462), filed on 10 March 2017.

BACKGROUND

Technical Field [0001a] This disclosure relates generally to position control and more specifically to position management with optical image stabilization in autofocus camera components.

Description of the Related Art [0002] The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some small form factor cameras may incorpórate optical image stabilization (OIS) mechanisms that may sense and react to extemal excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compénsate for unwanted motion of the lens. Some small form factor cameras may incorpórate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plañe in front of the camera at an image plañe to be captured by the image sensor. In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis (referred to as the Z axis) of the camera to refocus the camera.

[0003] In addition, high image quality is easier to achieve in small form factor cameras if lens motion along the optical axis is accompanied by minimal parasitic motion in the other degrees of freedom, for example on the X and Y axes orthogonal to the optical (Z) axis of the camera. Thus, some small form factor cameras that inelude autofocus mechanisms may also incorpórate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compénsate for unwanted motion of the lens.

Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

[0020] “Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units ...” Such a claim does not foreclose the apparatus from including additional components (e.g., anetwork interface unit, graphics circuitry, etc.).

[0021] “Configurad To.” Various units, circuits, or other components may be described or claimed as “configurad to” perform a task or tasks. In such contexts, “configurad to” is used to connote structure by indicating that the units/circuits/components inelude structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configurad to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configurad to” language inelude hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configurad to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112, sixth paragraph, for that unit/circuit/component. Additionally, “configurad to” can inelude generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to opérate in manner that is capable of performing the task(s) at issue. “Configure to” may also inelude adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabrícate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.

[0022] “First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “firsf ’ and “second” valúes. The terms “first” and “second” do not necessarily imply that the first valué must be written before the second valué.

[0023] “Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.

DETAILED DESCRIPTION

Introduction to magnetic sensing for autofocus position detection [0024] Some embodiments inelude camera equipment outfitted with Controls, magnets, and voice coil motors to improve the effectiveness of a miniature actuation mechanism for a compact camera module. More specifically, in some embodiments, compact camera modules inelude actuators to deliver functions such as autofocus (AF) and optical image stabilization (OIS). One approach to delivering a very compact actuator for OIS is to use a Voice Coil Motor (VCM) arrangement.

[0025] In some embodiments, the optical image stabilization actuator is designed such that the imagining sensor is mounted on an OIS frame which translates in X and Y (as opposed to an autofocus actuator that translates in Z, where Z is the optical axis of the camera). An electromechanical component for moving the image sensor is composed of a static and a dynamic platform. Mounting of an imaging sensor (wirebonding, flip/chip, BGA) on the dynamic platform with run out electrical signal traces from the dynamic platform to the static platform provides for connection to the image sensor. In-plane flexures connect the dynamic platform to the static platform and support electrical signal traces. OIS Coils are mounted on the dynamic platform. In some embodiments, OIS permanent magnets are mounted on the static platform to provide additional Lorentz forcé (e.g. in case of high in-plane flexure stiffness).

[0026] Some embodiments inelude a camera. The camera may inelude a lens, an image sensor, and a voice coil motor (VCM) actuator. The lens may inelude one or more lens elements that define an optical axis. The image sensor may be configured to capture light passing through the lens. Furthermore, the image sensor may be configured to convert the captured light into image signáis.

[0027] In some embodiments, a camera actuator ineludes an actuator base, an autofocus voice coil motor, and an optical image stabilization voice coil motor. In some embodiments, the autofocus voice coil motor ineludes 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 ineludes an image sensor carrier moveably mounted to the actuator base, and a plurality of 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.

[0028] Some embodiments provide an actuator system using a first AF VCM (voice coil motor), and a second OIS VCM to separately accomplish sensor shiñ. In some embodiments, the AF VCM actuator allows translation of the optics along the optical axis. In some embodiments, the OIS VCM actuator allows an image sensor to transíate in a plañe perpendicular to optical axis. In some embodiments, the sensor is mounted on a flat flexure where the electrical traces connecting image sensor and I/O termináis are achieved using an additive metal deposition process (e.g., a high precisión additive copper deposition process) directly on the flexure and where the in-plane translation forcé is a result of a VCM designed around a moving coil architecture.

[0029] In some embodiments, the elimination of OIS “optics shiñ” design that relies on vertical beams (suspensión wires) reduces challenges to reliability by relying on the OIS sensor shift and the design of the flat flexure to provide lower required yield strength and larger cross-section, both of which improve reliability.

[0030] In some embodiments, shifting the sensor allows reduction of the moving mass, and therefore there is a clear benefit in power consumption in comparison to OIS “optics shiñ” designs. In some embodiments, manufacturing is accomplished with the electrical traces directly deposited on the OIS flexure (e.g., using an additive metal deposition process), which enables smaller size package while satisfying the I/O requirements.

[0031] In some embodiments, the image sensor carrier further ineludes one or more flexible members for mechanically connecting an image sensor, which is fixed relative to the image sensor carrier, to a frame of the optical image stabilization voice coil motor.

[0032] In some embodiments, the image sensor carrier further ineludes one or more flexible members for mechanically and electrically connecting an image sensor, which is fixed relative to the image sensor carrier, to a frame of the optical image stabilization voice coil motor, and the flexures inelude electrical signal traces.

[0033] In some embodiments, the image sensor carrier further ineludes one or more flexible members for mechanically and electrically connecting an image sensor, in which is fixed relative to the image sensor carrier, to a frame of the optical image stabilization voice coil motor, and the flexuras inelude metal flexure bodies carrying electrical signal traces electrically isolated from the metal flexure bodies vía an insulator (e.g., one or more polymide insulator layers).

[0034] In some embodiments, the image sensor carrier further ineludes one or more flexible members for mechanically and electrically connecting an image sensor, in which is fixed relative to the image sensor carrier, to a frame of the optical image stabilization voice coil motor, and the flexuras inelude metal flexure bodies carrying múltiple layers of electrical signal traces electrically isolated from the metal flexure bodies and from one another vía an insulator.

[0035] In some embodiments, the optical image stabilization coils are mounted on a flexible printed circuit carrying power to the coils for operation of the optical image stabilization voice coil motor.

[0036] In some embodiments, the optical image stabilization coils are comer-mounted on a flexible printed circuit mechanically connected to the actuator base and mechanically isolated from the autofocus voice coil motor.

[0037] In some embodiments, a bearing surface end stop is mounted to the base for restricting motion of the optical image stabilization voice coil motor.

[0038] In some embodiments, a camera ineludes a lens in a lens carrier, an image sensor for capturing a digital representation of light transiting the lens, an axial motion voice coil motor for focusing light from the lens on the image sensor by moving a lens assembly containing the lens along an optical axis of the lens, and a transverse motion voice coil motor.

[0039] In some embodiments, the axial motion voice coil motor ineludes a suspensión assembly for moveably mounting the lens carrier to an actuator base, a plurality of shared magnets mounted to the actuator base, and a focusing coil fixedly mounted to the lens carrier and mounted to the actuator base through the suspensión assembly.

[0040] In some embodiments, the transverse motion voice coil motor ineludes an image sensor frame member, one or more flexible members for mechanically connecting the image sensor frame member to a frame of the transverse motion voice coil motor, and a plurality of transverse motion coils moveably mounted to the image sensor frame member within the magnetic fields of the shared magnets, for producing forces for moving the image sensor frame member in a plurality of directions orthogonal to the optical axis.

[0041] In some embodiments, the image sensor carrier further ineludes one or more flexible members for mechanically and electrically connecting an image sensor, in which is fixed relative to the image sensor carrier, to a frame of the optical image stabilization voice coil motor, and the flexures inelude electrical signal traces.

[0042] In some embodiments, the image sensor carrier further ineludes one or more flexible members for mechanically and electrically connecting an image sensor, in which is fixed relative to the image sensor carrier, to a frame of the optical image stabilization voice coil motor, and the flexures inelude metal flexure bodies carrying electrical signal traces electrically isolated from the metal flexure bodies vía an insulator.

[0043] In some embodiments, the optical image stabilization coils are mounted on a flexible printed circuit carrying power to the coils for operation of the optical image stabilization voice coil motor.

[0044] In some embodiments, the optical image stabilization coils are comer-mounted on a flexible printed circuit mechanically connected to the actuator base and mechanically isolated from the autofocus voice coil motor.

[0045] In some embodiments, a bearing surface end stop is mounted to the base for restricting motion of the optical image stabilization voice coil motor.

[0046] In some embodiments, a bearing surface end stop is mounted to the actuator base for restricting motion of the image sensor along the optical axis.

[0050] As used herein, the term "if may be construed to mean "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [a stated condition or event] is detected" may be construed to mean "upon determining" or "in response to determining" or "upon detecting [the stated condition or event]" or "in response to detecting [the stated condition or event]," depending on the context.

[0051] FIGS. 1 and 2 illustrate an example camera 100 having an actuator module or assembly that may, for example, be used to provide autofocus through optics assembly movement and/or optical image stabilization through image sensor movement in small form factor cameras, according to at least some embodiments. Camera 100 may inelude an optics assembly 102. The optics assembly 102 may carry one or more lenses 104 (also referred to herein as the “lens”). In some cases, the optics assembly may be moveably connected to an actuator base. The lens 104 may be held with a lens barrel, which may in tum be connected to a lens carrier 106, although it should be appreciated that the lens barrel and lens carrier 106 may be a common component in some embodiments. In some embodiments, camera 100 ineludes an image sensor 108 for capturing a digital representation of light transiting the lens 104. Camera 100 may inelude an axial motion (autofocus) voice coil motor 110 for focusing light from the lens 104 on the image sensor 108 by moving the optics assembly 102 containing the lens 104 along an optical axis of the lens 104. In some examples, the axial motion voice coil motor 110 ineludes a suspensión assembly 112 for moveably mounting the lens carrier 106 to an actuator base 114. Furthermore, the axial motion voice coil motor 110 may inelude a plurality of shared magnets 116 mounted to the actuator base 114, and a focusing coil 118 fixedly mounted to the lens carrier 106 and mounted to the actuator base 114 through the suspensión assembly 112. In some embodiments, the actuator base 114 can be made from múltiple sepárate components.

[0052] In various embodiments, camera 100 ineludes a transverse motion (optical image stabilization (OIS)) voice coil motor 120. The transverse motion voice coil motor 120 may inelude an image sensor frame member 122, one or more flexible members 124 (also referred to herein as “flexures”, “flexure arms”, or “spring arms”) for mechanically connecting the image sensor frame member 122 (also referred to herein as the “dynamic platform” or “inner frame”) to a frame of the transverse motion voice coil motor 126 (also referred to herein as the “static platform” or “outer frame”), and a plurality of OIS coils 132. As indicated in FIG. 2, the OIS coils 132 may be mounted to the dynamic platform 122 within the magnetic fields 138 of the shared magnets 116, for producing forces 140 for moving the dynamic platform 122 in a plurality of directions orthogonal to the optical axis of the lens 104.

[0053] In some embodiments, the dynamic platform 122, the flexuras 124 for mechanically connecting the dynamic platform 122 to the static platform 126, and the static platform 126 are a single metal part or other flexible part.

In some embodiments, the flexuras 124 inelude metal flexure bodies carrying electrical signal traces 130 electrically isolated from the metal flexure bodies vía an insulator.

[0054] In some examples, the OIS coils 132 are mounted on a flexible printed circuit (FPC) 134 carrying power to the OIS coils 132 for operation of the transverse motion (OIS) voice coil motor 120. The flexible printed circuit 134, the dynamic platform 136, the flexuras 124, and/or the static platform 126 may be connected to a top surface of the actuator base 114 in some embodiments.

[0055] In some embodiments, a bearing surface end stop 136 is mounted to the actuator base 114 for restricting motion of the image sensor 108 along the optical axis.

[0056] For OIS coil control, in some embodiments control circuitry (not shown) may be positioned on the dynamic platform 122 and/or the FPC 134, and power may be routed to the control circuitry via one or more of the flexuras 124. In other instances, the control circuitry may be positioned off of the dynamic platform 122, and stimulation signáis may be carried to the OIS coils 132 from the control circuitry via one or more of the flexuras 124.

[0057] FIGS. 3-5 illustrate components of an example camera 300 having an actuator module or assembly that may, for example, be used to provide autofocus (AF) through optics assembly movement and/or optical image stabilization (OIS) through image sensor movement in small form factor cameras, according to at least some embodiments. FIG. 3 shows an exploded view of the camera 300. FIG. 4 shows a cross-sectional view of the camera 300. FIG. 5 shows a perspective view of the exterior of the camera 300. In various embodiments, the camera 300 may inelude an optics assembly 302, a shield can 304, a magnet holder 306, a magnet 308, a lens carrier 310, an AF coil 312, a base 314, an OIS coil 316, an OIS FPC 318, an image sensor 320, an OIS frame 322 (e.g., in accordance with one or more embodiments of the flexure modules described herein with reference to FIGS. 7A-11B), and/or electrical traces 324.

[0058] In various examples, the shield can 304 may be mechanically attached to the base 314. The camera 300 may inelude an axial motion (AF) voice coil motor (VCM) (e.g., axial motion VCM 110 discussed above with reference to FIGS. 1 and 2) and/or a transverse motion (OIS) VCM (e.g., transverse motion VCM 120 discussed above with reference to FIGS. 1 and 2).

Furthermore, the transverse motion VCM may inelude the OIS coil 316, the OIS FPC 318, the image sensor 320, the OIS frame 322, and/or the electrical traces 324. In some examples, the axial motion VCM (or a portion thereof) may be connected to the shield can 304, while the transverse motion VCM (or a portion thereof) may be connected to the base 314.

[0059] In some embodiments, the OIS FPC 318 and/or the OIS frame 322 may be connected to a bottom surface of the base 314. In some examples, the base 314 may define one or more recesses and/or openings having múltiple different cross-sections. For instance, a lower portion of the base 314 may have may define a recess and/or an opening with a cross-section sized to receive the OIS frame 322. An upper portion of the base 314 may define a recess and/or an opening with a cross-section sized to receive the OIS FPC 318. The upper portion may have an inner profile corresponding to the outer profile of the OIS FPC 318. This may help to maximize the amount of material included in the base 314 (e.g., for providing structural rigidity to the base 314) while still providing at least a mínimum spacing between the OIS FPC 318 and the base 314.

[0060] In some non-limiting examples, the OIS FPC 318 and the image sensor 320 may be separately attached to the OIS frame 322. For instance, a first set of one or more electrical traces may be routed between the OIS FPC 318 and the OIS frame 322. A second, different set of one or more electrical traces may be routed between the image sensor and the OIS frame 322. In other embodiments, the image sensor 320 may be attached to or otherwise integrated into the OIS FPC 318, such that the image sensor 320 is connected to the OIS frame 322 vía the OIS FPC 318, e.g., as discussed below with reference to FIG. 6.

[0061] FIG. 6 illustrates a cross-sectional view of an example transverse motion voice coil motor (VCM) 600 that may be used, for example, in a camera to provide optical image stabilization (OIS), in accordance with some embodiments. In some embodiments, the transverse motion VCM 600 may inelude an OIS frame 602, an image sensor 604, an OIS Hat printed circuit (FPC) 606, and/or an OIS coil 608. The OIS frame 602 may inelude a dynamic platform 610, a static platform 612, and one or more flexures 614. The flexures 614 may connect the dynamic platform 610 to the static platform 612. In some examples, one or more of the flexures 614 may inelude one or more electrical traces 616 routed between the static platform 612 and the dynamic platform 610 and/or the OIS FPC 606.

[0062] In some embodiments, the image sensor 604 may be attached to or otherwise integrated into the OIS FPC 606 such that the image sensor 604 is connected to the OIS frame 602 vía the OIS FPC 606, e.g., as depicted in FIG. 6. In some examples, there may be one or more trace connections 618 between the OIS FPC 606 and the OIS frame 602. In some cases, the OIS frame 602 may have a hole 620 extending therethrough, and a portion of the OIS FPC 606 and/or the image sensor 604 may extend at least partially through the hole 620. This may allow for a reduction in z height (e.g., the height of the transverse motion VCM 600 along an optical axis of the camera) in some cases.

[0063] In some examples, the OIS FPC 606 may extend from the dynamic platform 610 such that a portion of the OIS FPC 606 is positioned over the flexures 614 (e.g., in a plañe above the flexures 614). In some examples, at least a portion of each of the OIS coils 608 to be positioned above the flexures 614. Such an arrangement may facilítate miniaturization of the transverse motion VCM 600 and/or the camera, as the dynamic platform 610 need not be sized to accommodate both the image sensor 604 and the OIS coils 608.

[0064] FIGs. 7A-7C depict an example embodiment of frames and flexures 700 of a camera having an actuator module or assembly that may, for example, be used to provide autofocus through optics assembly movement and/or optical image stabilization through image sensor movement in small form factor cameras, according to at least some embodiments. An image sensor 702 rests on, or is otherwise coupled to, a dynamic platform 704 of an OIS frame connected to a static platform 706 of the OIS frame by flexures 708 carrying electrical traces710. The traces 710 may be electrically insulated (e.g., from each other, from other flexures 708, from the OIS frame, etc.) vía an insulator 712, e.g., as indicated in FIG. 7C. The traces 710 may be formed from a metal material (e.g., copper). In some examples, the traces 710 may be formed using an additive metal deposition process, such as an additive copper deposition process. Similarly, the insulator 712 may be made from polyimide.

[0065] In some embodiments, the OIS frame may inelude múltiple flexure groups. Each flexure group may be múltiple flexures 708 that are connected to a common side of the dynamic platform 704 and a common side of the static platform 706. In some examples, at least one flexure group is configured such that the flexures 708 connect to a side of the dynamic platform 704 and a noncorresponding side of the static platform 706. That is, the each side of the dynamic platform 704 may face a corresponding side of the static platform 706, and the flexure 708 may inelude at least one bend or curve to traverse a comer to reach a non-corresponding side of the static platform 706, e.g., as depicted in FIGS. 7A and 7B.

[0066] In some cases, one or more sides of the dynamic platform 704 and/or the static platform 706 may inelude múltiple flexure groups. For instance, as shown in FIG. 7A, a first side of the dynamic platform 704 may inelude two flexure groups. One flexure group may connect the first side of the dynamic platform 704 to a first non-corresponding side of the static platform 706, while the other flexure group may connect the first side of the dynamic platform 704 to a second non-corresponding side of the static platform 706. In some cases, the first non-corresponding side and the second non-corresponding side of the static platform 706 may be opposite each other. A second side of the dynamic platform 704 may inelude two flexure groups that are connected in a similar manner to the static platform 706. In some cases, the first side and the second side of the dynamic platform 704 may be opposite each other.

[0067] FIGS. 8A-8B each illustrate a view of an example flexure module 800 of a voice coil motor (VCM) actuator that may be used, for example, in a camera to provide optical image stabilization, in accordance with some embodiments. FIG. 8A illustrates a top view of the flexure module 800. FIG. 8B illustrates a perspective view of the flexure module 800.

[0068] In some embodiments, the flexure module 800 may be used in a transverse motion (optical image stabilization) voice coil motor of a camera (e.g., the cameras described above with reference to FIGS. 1-5). The flexure module 800 may inelude a dynamic platform 802 and a static platform 804. In some examples, the dynamic platform 802 and/or the static platform 804 may be configurad in accordance with one or more embodiments described herein with reference to FIGS. 1-7C and 9A-13. However, various other configurations of the dynamic platform 802 and/or the static platform 804 that are suitable for use with a VCM actuator fall within the scope of this disclosure.

[0069] In various examples, the flexure module 800 may inelude one or more flexuras 806. The flexuras 806 may be configurad to mechanically connect the dynamic platform 802 to the static platform 804. The flexuras 806 may be configurad to provide stifíhess (e.g., in-plane flexure stiffness) to the VCM actuator while allowing the dynamic platform 802 (and an image sensor fixed relative to the dynamic platform 802) to move along a plañe that is orthogonal to an optical axis defined by one or more lenses of a camera. In this manner, the image sensor may be shifted along the plañe that is orthogonal to the optical axis to provide optical image stabilization functionality. Furthermore, as described herein with reference to FIGS. 1-7C, 10B-10E, 11A-11B, and 13, one or múltiple flexuras 806 may inelude electrical traces configurad to convey signáis (e.g., image signáis generated by the image sensor fixed relative to the dynamic platform 802) from the dynamic platform 802 to the static platform 804.

[0070] In various embodiments, the flexure module 800 may inelude one or more flexure stabilizer members 808. The flexure stabilizer members 808 may be configurad to mechanically connect flexuras 806 to each other such that the flexure stabilizer members 808 prevent interference between the flexuras 806 that are connected by the flexure stabilizer members 808. For instance, the flexure stabilizer members 808 may be configurad to prevent the flexuras 806 from colliding and/or entangling with one another, e.g., in drop events, vibration events, etc.

Additionally, or altematively, the flexure stabilizer members 808 may be configured to limit motion of, and/or stabilize relative motion between, the flexures 806 that are connected by the flexure stabilizer members 808. Furthermore, the flexure stabilizer members 808 may be arranged along various portions of the flexures 806 to provide in-plane stiffness as needed in the flexure module 800, e.g., to satisfy optical image stabilization design requirements. Some nonlimiting examples of flexure stabilizer member configurations are described below with reference to FIGS. 9A-9L.

[0071] In some embodiments, the flexures 806 may be arranged in one or more flexure groups 810, or arrays, that individually inelude múltiple flexures 806. For instance, as depicted in FIGS. 8A-8B, the flexure module 800 ineludes a first flexure group 810a, a second flexure group 810b, a third flexure group 810c, and a fourth flexure group 810d. In some examples, the flexures 806 of a flexure group 810 may be parallel to each other along a plañe that is orthogonal to the optical axis. In some cases, the flexures 806 of one flexure group 810 (e.g., the first flexure group 810a) may not be parallel to the flexures 806 of another flexure group 810 (e.g., the second flexure group 810b). In some cases, one or more of the flexure groups 810 may inelude one or more flexure stabilizer members 808. For instance, each of the flexure groups 810 may inelude one or more flexure stabilizer members 808. Furthermore, one or more of the flexure groups 810 may inelude one or more bend (or “tum”) portions. In some cases, at least one of the flexure groups 810 may inelude a flexure stabilizer member 808 disposed at a bend portion. For example, in FIGS. 8A-8B, each of the flexure groups 810 bend at three respective bend portions, and a respective flexure stabilizer member 808 connects the flexures 806 of respective flexure groups 810 at one respective bend portion of the three respective bend portions.

[0072] In some examples, the dynamic platform 802 and/or the static platform 804 may inelude one or more offsets 812 (e.g., a recess, an extensión, etc.). In some cases, one or more flexures 806 may connect to the dynamic platform 802 and/or the static platform 804 at an offset 812. For instance, as illustrated in FIGS. 8A-8B, the dynamic platform 802 may inelude two recess offsets 812 at opposing sides of the dynamic platform 802. However, in some embodiments, the dynamic platform 802 and/or the static platform 804 may inelude a different offset configurad on. Some non-limiting examples of offset configurations are described below with reference to FIGS. 9A-9L.

[0073] FIGS. 9A-9L each illustrate a pardal top view of a respective example flexure module configurad on, in accordance with some embodiments. In some cases, one or more embodiments of the example flexure module configurations of FIGS. 9A-9L may be used in a flexure module (e.g., the flexure modules described herein with reference to FIGS. 8A-8B and 11A-12B) of a voice coil motor (VCM) actuator. The VCM actuator may be used, for example, in a camera (e.g., the cameras described above with reference to FIGS. 1-5) to provide optical image stabilization.

[0074] The example flexure module configurations of FIGS. 9A-9L provide some non-limiting examples of design feature variations that may be used in one or more embodiments of the flexure modules, VCM actuators, and/or cameras described herein.

[0075] FIG. 9A illustrates a partial top view of a flexure module configuration 900a, in accordance with some embodiments. The flexure module configuration 900a ineludes a dynamic platform 902a, a static platform 904a, flexures 906a, and a flexure stabilizer member 908a. The flexures 906a may be part of a flexure group that extends from the dynamic platform 902a to the static platform 904a. A side of the dynamic platform 902a may define a recess at which the flexures 906a are attached to the dynamic platform 902a. A non-corresponding side of the static platform 904a may define an extensión at which the flexures 906a are attached to the static platform 904a. In its extensión from the recess of the dynamic platform 902a to the extensión of the static platform 904a, the flexure group may inelude one or more bends. For instance, the flexure group may inelude a first bend to traverse a first comer formed by the recess of the dynamic platform 902a, a second bend to traverse a comer adjacent two sides of the dynamic platform 902a, and a third bend to orient the flexure group towards the extensión of the static platform 904a. In some examples, a respective portion of the flexure group may be oriented orthogonal to the recess of the dynamic platform 902a and/or orthogonal to the extensión of the static platform 904a at or near respective connection locations. In some embodiments, the recess of the dynamic platform 902a may allow for an increased length of the flexures 906a, which in tum may provide for additional flexibility for the flexures 906a.

[0076] FIG. 9B illustrates a partial top view of a flexure module configuration 900b, in accordance with some embodiments. The flexure module configuration 900b ineludes a dynamic platform 902b, a static platform 904b, flexures 906b, and flexure stabilizer members 908b. In some embodiments, the dynamic platform 902b, the static platform 904b, and the flexures 906b may be configured like the dynamic platform 902a, the static platform 904a, and the flexures 906a, respectively, described above with reference to FIG. 9A. However, the flexure module configuration 900b may inelude múltiple flexure stabilizer members 908b. For instance, each bend of the flexure group may inelude a respective flexure stabilizer member 908b.

[0077] FIG. 9C illustrates a partial top view of a flexure module configuration 900c, in accordance with some embodiments. The flexure module configuration 900c ineludes a dynamic platform 902c, a static platform configuration 904c, flexures 906c, and a flexure stabilizer member 908c. The flexures 906c may be part of a flexure group that extends from the dynamic platform 902c to the static platform 904c. A side of the dynamic platform 902c may define a first extensión at which the flexuras 906c are attached to the dynamic platform 902c. A noncorresponding side of the static platform 904c may define a second extensión at which the flexuras 906c are attached to the static platform 904c. In its extensión from the first extensión of the dynamic platform 902c to the second extensión of the static platform 904c, the flexure group may inelude one or more bends. For instance, the flexure group may inelude a first bend to traverse a comer adj acent two sides of the dynamic platform 902c, and a second bend to orient the flexure group towards the second extensión of the static platform 904c. In some embodiments, the first extensión of the dynamic platform 902c may allow for a reduced length of the flexuras 906c and/or a reduced number of bends of the flexuras 906c, which in tum may provide for increased stiffness of the flexuras 906c.

[0078] In some embodiments, an extensión and/or a recess of a dynamic platform and/or a static platform may change the direction that the flexuras attach relative to the dynamic platform and/or the static platform. For example, in FIG. 8C, the flexuras 906c are connected to the second extensión of the static platform 904c such that the flexuras 906c extend from the second extensión in a direction toward a corresponding side of the dynamic platform 902c (and thus the flexuras 906c bend to avoid contact with the corresponding side of the dynamic platform 902c) while the flexuras 906c are connected to the first extensión of the dynamic platform 902c in a direction toward a non-corresponding side of the static platform 904c (and thus the flexuras 906c do not need a bend to avoid contact with the corresponding side of the static platform 904c). [0079] In some examples, the second extensión of the static platform 904c may be used to provide additional space for routing of traces (e.g., for grounding of guard traces, as discussed below with reference to FIG. 101).

[0080] FIG. 9D illustrates a partial top view of a flexure module configuration 900d, in accordance with some embodiments. The flexure module configuration 900d ineludes a dynamic platform 902d, a static platform 904d, and flexuras 906d. The flexuras 906d may be part of a flexure group that extends from the dynamic platform 902d to the static platform 904d. A side of the dynamic platform 902d may define a first extensión at which the flexuras 906d are attached to the dynamic platform 902d. A non-corresponding side of the static platform 904d may define a second extensión at which the flexuras 906d are attached to the static platform 904d. In its extensión from the first extensión of the dynamic platform 902d to the second extensión of the static platform 904d, the flexure group may inelude one or more bends. For instance, the flexure group may inelude a bend to traverse a comer (which may inelude, e.g., a chamfer, fillet, etc.) adj acent two sides of the dynamic platform 902d. In some embodiments, the first extensión of the dynamic platform 902d may allow for a reduced length of the flexuras 906d and/or a reduced number of bends of the flexures 906d, which in tum may provide for increased stiffness of the flexures 906d.

[0081] In some examples, certain electrical traces (and the signáis they carry) may be susceptible to physical deformations. In instances where different electrical traces have different thicknesses and/or strengths, the electrical traces may be routed along different flexures 906d and/or different types of flexures 906d, e.g., based at least in part on sensitivity of the electrical traces. For example, in FIG. 9D, the flexure group may inelude flexures 906d of varying shapes and/or thicknesses. From outermost flexure 906d to innermost flexure 906d, the first (outermost) flexure 906d and second flexure 906d have a first shape and a first thickness that is consistent throughout the flexures, the third flexure 906d has a second shape and a second thickness that varíes at different portions of the flexure, and the fourth (innermost) flexure 906d has a third shape and a third thickness that varíes at different portions of the flexure. In some cases, the first shape, the second shape, and/or the third shape may be different from one another. In some embodiments, each of the second shape and the third shape may inelude a respective bend that is chamfered. In some instances, the fourth (innermost) flexure 906d may inelude a chamfered bend proximate a chamfered comer of the dynamic platform 902d. Furthermore, the fourth (innermost) flexure 906d may define a through hole at or proximate the chamfered bend.

[0082] FIG. 9E illustrates a partial top view of a flexure module configuration 900e, in accordance with some embodiments. The flexure module configuration 900e ineludes a dynamic platform 902e, a static platform 904e, and flexures 906e.

[0083] FIG. 9F illustrates a partial top view of a flexure module configuration 900f, in accordance with some embodiments. The flexure module configuration 900f ineludes a dynamic platform 902f, a static platform 904f, flexures 906f, and flexure stabilizer members 908f.

[0084] FIG. 9G illustrates a partial top view of a flexure module configuration 900g, in accordance with some embodiments. The flexure module configuration 900g ineludes a dynamic platform 902g, a static platform 904g, and flexures 906g.

[0085] FIG. 9H illustrates a partial top view of a flexure module configuration 900h, in accordance with some embodiments. The flexure module configuration 900h ineludes a dynamic platform 902h, a static platform 904h, and flexures 806h.

[0086] FIG. 91 illustrates a partial top view of a flexure module configuration 900i, in accordance with some embodiments. The flexure module configuration 900i ineludes a dynamic platform 902i, a static platform 904i, flexures 906i, and flexure stabilizer members 908i. In some embodiments, the static platform 904i may inelude a chamfered comer proximate the outermost flexure 906i. In some instances, the inner surface of the static platform 904i may have a profile that follows the profile of the flexures 906i as well as at least a portion of the outer profile of the dynamic platform 902i. Such an arrangement may be used to provide at least a mínimum spacing between the flexures 906i and the dynamic platform 902i and/or the static platform 904i. It should be appreciated that the components may have different profdes, but some other profdes may reduce useable area of the dynamic platform and/or the static platform, and/or increase the overall size of an OIS frame.

[0087] FIG. 9J illustrates a partial top view of a flexure module configuration 900j, in accordance with some embodiments. The flexure module configuration 900j ineludes a dynamic platform 902j, a static platform 904j, and flexures 906j.

[0088] FIG. 9K illustrates a partial top view of a flexure module configuration 900k, in accordance with some embodiments. The flexure module configuration 900k ineludes a dynamic platform 902k, a static platform 904k, flexures 906k, and flexure stabilizer members 908k.

[0089] FIG. 9L illustrates a partial top view of a flexure module configuration 9001, in accordance with some embodiments. The flexure module configuration 9001 ineludes a dynamic platform 9021, a static platform 9041, flexures 9061, and flexure stabilizer members 9081.

[0090] With respect to flexures, some of the example flexure module configurations of FIGS. 9A-9L indícate variations of the flexures that inelude, but are not limited to, one or more of the following: [0091] (la) The number of flexures may vary. For instance, a flexure module may inelude one or múltiple flexures. In a particular example, a flexure module may inelude three to six flexures in a flexure group. As a non-limiting examples, the flexure group shown in FIG. 9A ineludes five flexures, while the flexure group shown in FIG. 9J ineludes four flexures. The number of flexures in a flexure group may impact the stiffness of the flexure group. In some instances, a greater number of flexures may correspond to a higher stiffness of the flexure group.

[0092] (2a) The flexures may be parallel to each other. For instance, the flexure groups shown in FIGS. 9A-9C, 9E, 9F, 9H, 91, 9K, and 9L have flexures that are parallel to each other. However, the flexures do not need to be parallel to each other. For examples, the flexure groups shown in FIGS. 9D, 9G, and 9J inelude flexures that are not parallel to each other.

[0093] (3a) The flexures may be parallel to a frame edge (e.g., an edge of a dynamic platform and/or a static platform of a flexure module). For instance, each of FIGS. 9A-9L inelude portions of one or more flexures that are parallel to the dynamic platform and/or the static platform. In some examples, portions of one or more flexures of a flexure group may not be parallel to the dynamic platform and/or the static platform. For instance, in FIG. 9G, portions of the flexures 906g are not parallel to the dynamic platform 902g or the static platform 904g.

[0094] (4a) The flexures may be evenly spaced apart from each other. As a non-limiting example, the flexure groups shown in FIG. 9A-9C, 9E, 9F, 9H, 91, 9K, and 9L inelude flexures that are evenly spaced apart from each other. In other examples, the flexuras may not be evenly spaced apart from each other. For instance, the flexure groups shown in FIGS. 9D, 9G, and 9J inelude flexuras that are not evenly spaced apart from each other.

[0095] (5a) A width of a flexuras may vary along the flexuras and/or among the flexuras. For instance, the flexure group shown in FIG. 9D ineludes flexuras with such width variations.

[0096] (6a) The flexuras may inelude features (e.g., a recess, an extensión, an apertura, etc.). For instance, the flexure group shown in FIG. 9D ineludes an innermost flexure that defines an apertura.

[0097] (7a) A cross-section of the flexuras may be rectangular, concave, and/or convex in shape, e.g., as discussed below with reference to FIGS. 10A-10J.

[0098] (8a) The flexuras may be a solid material, ciad, or switched beam, e.g., as discussed below with reference to FIGS. 10A-10J.

[0099] With respect to bends of the flexuras (or flexure groups), some of the example flexure module configurations of FIGS. 9A-9L indícate bend variations that inelude, but are not limited to, one or more of the following: [00100] (Ib) The flexuras may inelude one or more bends. For example, the flexuras shown in FIGS. 9A and 9B have three bends, while the flexuras shown in FIG. 9C have two bends, and the flexuras shown in FIG. 9D have one bend.

[00101] (2b) A tuming angle of the bends may vary. In some examples, the tuming angle may be 90 degrees. For instance, the flexure group shown in FIG. 9A ineludes bends that have 90 degree tuming angles. However, in other examples, the tuming angle may be an angle other than 90 degrees. For instance, the innermost flexure shown in FIG. 9G has a bend with a tuming angle that is not 90 degrees.

[00102] (3b) The tuming radii of the bends may vary. For example, the flexure groups shown in FIGS. 9D and 9J inelude flexuras with bends that have varying tuming radii.

[00103] With respect to flexure stabilizer members, some of the example flexure module configurations of FIGS. 9A-9L indícate variations of the flexure stabilizer members that inelude, but are not limited to, one or more of the following: [00104] (le) One or more flexure stabilizer members may connect the flexuras. For example, in FIG. 9A, a single flexure stabilizer member connects the flexuras at one of the three bends of the flexure group. In FIG. 9B, three flexure stabilizer members are used to connect the flexuras, with each flexure connecting the flexuras at a respective bend of the flexure group.

[00105] (2c) A flexure stabilizer member may connect some or all of the flexuras. For instance, in FIG. 9A, a flexure stabilizer member connects all of the flexuras of the flexure group. The flexure groups shown in FIGS. 9F and 9L inelude flexure stabilizer members that connect some, but not all, of the flexures. In some cases, a flexure stabilizer member may be used to connect two adj acent flexures to each other without connecting those flexures to any other flexures.

[00106] (3c) The locations of the flexure stabilizer members may be anywhere on the flexures.

In some examples, the locations of the flexure stabilizer members may be different among the flexures. For instance, in FIGS. 9F and 9L, the locations of the flexure stabilizer members are different among the flexures. Furthermore, in FIG. 9F, the number of flexure stabilizer members connecting the flexures varíes. Some of the flexures are connected vía two flexure stabilizer members, while other flexures are connected via three flexure stabilizer members. In some instances, a width and/or a thickness of the flexure stabilizer members may vary, with some being wider and/or thicker than others, e.g., as illustrated in FIG. 9F.

[00107] (4c) An angle between the flexure stabilizer members and the flexures may vary. In some examples, the angle between the flexure stabilizer member and the flexures may be 90 degrees, e.g., as shown in FIGS. 9A-9C, 9F, 91, and 9L. However, in other examples, the angle may be an angle other than 90 degrees, e.g., as shown in FIG. 9K.

[00108] With respect to offsets of the dynamic platform and/or the static platform, some of the example flexure module configurations of FIGS. 9A-9L indícate variations of the offsets that inelude, but are not limited to, one or more of the following: [00109] (Id) An offset may exist at a flexure root where flexures connect to the dynamic platform and/or the static platform, e.g., as shown in FIGS. 9A-9L.

[00110] (2d) The offset may be, for example, a recess, an extrusión, etc. For instance, FIGS. 9A, 9B, 9F, and 9K show a recess at the dynamic platform and an extensión at the static platform. FIGS. 9C, 9D, 9E, 9G, 91, 9J, and 9L show an extensión at the dynamic platform and an extensión at the static platform.

[00111] With respect to flexure connecting angles to the dynamic platform and/or the static platform, some of the example flexure module configurations of FIGS. 9A-9L indícate variations of the flexure connecting angles that inelude, but are not limited to, one or more of the following: [00112] (le) The flexure connecting angles may vary. In some examples, a flexure connecting angle may be 90 degrees, e.g., as shown in FIGS. 9A-9D, 9F, 9H, and 9J-9L. However, in other examples, the flexure connecting angle may be an angle other than 90 degrees, e.g., as shown in FIGS. 9E, 9G, and 91.

[00113] (2e) Different flexures may have different flexure connecting angles, e.g., as shown in FIG. 9G.

[00114] (3e) For dynamic platforms and/or static platforms with an offset, the flexures may be connected to any available edge of the offset. In some cases, the flexures may be connected to an edge of the offset that is parallel to the side of the dynamic platform or the static platform that defines the offset, e.g., as shown in FIGS. 9A-9C, 9F, 9H, and 9K. In some examples, the flexures may be connected to an edge of the offset that is orthogonal to the side of the dynamic platform or the static platform that defines the offset, e.g., as shown in FIGS. 9D, 9J, and 9L. In some cases, the flexures may be connected to a slanted edge of the offset that is at an angle to the side of the dynamic platform or the static platform that defines the offset, e.g., as shown in FIGS. 9E, 9G, and 91. In some embodiments, the slanted edges may be used to individually adjust the lengths of different flexures.

[00115] With respect to flexure pattems (which, in some cases, may inelude a pattem formed by the flexures and the flexure stabilizer members), some of the example flexure module configurations of FIGS. 9A-9L indícate variations of the flexure pattems that inelude, but are not limited to, one or more of the following: [00116] (lf) The flexure pattem may be symmetric. For instance, the flexure pattem may be symmetric along at least two axes (e.g., the x and y axes) that are orthogonal to the optical axis. For example, the flexure pattems shown in FIGS. 3, 7A, 8A, and 8B are symmetric along two axes.

[00117] (lg) The flexure pattem may be asymmetric. For instance, the flexure pattem may be asymmetric along at least one axis (e.g., the x axis or the y axis) that is orthogonal to the optical axis. For instance, a flexure pattem may inelude múltiple different ones of the flexure module configurations shown in FIGS. 9A-9L such that the flexure pattem is asymmetric along the x axis and/or the y axis.

[00118] FIGS. 10A-10J illustrate views of example flexures and/or traces, in accordance with some embodiments. In some cases, one or more embodiments of the example flexures may be used in a flexure module (e.g., the flexure modules described herein with reference to FIGS. 8A-8B and 11A-12B) of a voice coil motor (VCM) actuator. The VCM actuator may be used, for example, in a camera (e.g., the cameras described above with reference to FIGS. 1-5) to provide optical image stabilization.

[00119] FIG. 10A illustrates a cross-sectional view of a flexure 1000a, in accordance with some embodiments. For instance, the cross-sectional view of the flexure 1000a may be taken along a plañe that is parallel to the optical axis. The flexure 1000a may have a width dimensión (denoted as “w” in FIG. 10A) and a height dimensión (denoted as “h” in FIG. 10A). In some examples, the height dimensión may be greater than the width dimensión. For instance, in a particular embodiment, the height dimensión may be about 120 micrometers and the width dimensión may be about 30 micrometers. It should be understood that the height dimensión and/or the width dimensión may be any other suitable dimensión.

[00120] FIG. 10B illustrates a cross-sectional view of a flexure 1000b, in accordance with some embodiments. The flexure 1000b may inelude an electrical trace 1002b. The electrical trace 1002b may be configured to convey signáis (e.g., image signáis) from a dynamic platform to a static platform. The electrical trace 1002b may be routed along at least a portion of the flexure 1000b. In some examples, the electrical trace 1002b may be located at a top portion of the flexure 1000b. In other examples, however, the electrical trace 1002b may additionally or altematively be located at a middle and/or bottom portion of the flexure 1000b. In some cases, the electrical trace 1002b may be a conductive material. For instance, the electrical trace 1002b may be a copper deposition on the flexure 1000b. In some embodiments, the electrical trace 1002b may be electrically insulated. For instance, the electrical trace 1002b may be at least partially coated by a dielectric material 1004b (e.g., apolyimide).

[00121] FIG. 10C illustrates a cross-sectional view of a flexure 1000c, in accordance with some embodiments. The flexure 1000c may inelude múltiple electrical traces 1002c (e.g., the electrical trace 1002b described above with reference to FIG. 10B). The electrical traces 1002c may be oriented side-by-side horizontally such that a horizontal plañe passes through the electrical traces 1002c. The electrical traces 1002c may be routed along at least a portion of the flexure 1000c. In some examples, the electrical traces 1002c may be located at a top portion of the flexure 1000c. In other examples, however, the electrical traces 1002c may additionally or altematively be located at a middle and/or bottom portion of the flexure 1000c. In some embodiments, the electrical traces 1002c may be electrically insulated from the rest of the flexure 1000c and/or from each other. For instance, the electrical traces 1002c may each be at least partially coated by a dielectric material 1004c (e.g., a polyimide).

[00122] FIG. 10D illustrates a cross-sectional view of a flexure lOOOd, in accordance with some embodiments. The flexure lOOOd may inelude múltiple electrical traces 1002d (e.g., the electrical trace 1002b described above with reference to FIG. 10B). The electrical traces 1002d may be oriented side-by-side vertically such that a vertical plañe passes through the electrical traces 1002d. The electrical traces 1002d may be routed along at least a portion of the flexure lOOOd. In some examples, the electrical traces 1002d may be located at a top portion of the flexure lOOOd. In other examples, however, the electrical traces 1002d may additionally or altematively be located at a middle and/or bottom portion of the flexure lOOOd. In some embodiments, the electrical traces 1002d may be electrically insulated from the rest of the flexure lOOOd and/or from each other. For instance, the electrical traces 1002d may each be at least partially coated by a dielectric material 1004d (e.g., apolyimide).

[00123] FIG. 10E illustrates a cross-sectional view of a flexure lOOOe, in accordance with some embodiments. The flexure lOOOe may inelude múltiple electrical traces 1002e (e.g., the electrical trace 1002b described above with reference to FIG. 10B). The electrical traces 1002e may be routed from a dynamic platform to a static platform along at least a portion of the flexure lOOOe. In some cases, one or more of the electrical traces 1002e may be located at a top portion of the flexure lOOOe, and one or more of the electrical traces 1002e may be located at a top portion of the flexure lOOOe. In some embodiments, the electrical traces 1002d may be electrically insulated from the rest of the flexure lOOOe and/or from each other. For instance, the electrical traces 1002d may each be at least partially coated by a dielectric material 1004e (e.g., a polyimide).

[00124] FIG. 10F illustrates a cross-sectional view of a flexure lOOOf, in accordance with some embodiments. The flexure lOOOf may be formed of múltiple materials. For instance, the flexure lOOOf may inelude a first material 1002f that sandwiches a second material 1004f. In some examples, the first material 1002f and/or the second material 1004f may inelude or be one or more electrical traces (e.g., the electrical trace 1002b described above with reference to FIG. 10B).

[00125] FIG. 10G illustrates a cross-sectional view of a flexure lOOOg, in accordance with some embodiments. The flexure lOOOg may inelude a concave portion 1002g.

[00126] FIG. 10H illustrates a cross-sectional view of a flexure lOOOh, in accordance with some embodiments. The flexure lOOOh may inelude a convex portion 1002h.

[00127] FIG. 101 illustrates a cross-sectional view of a flexure configuration 1000Í, in accordance with some embodiments. In some embodiments, the flexure configuration lOOOi may inelude a first flexure 1002i, a second flexure 1004i, a third flexure 1006i, and/or a fourth flexure 1008i.

[00128] In some embodiments, an OIS frame may be formed from a conductive material (e.g., a copper alloy, stainless Steel, or the like), such that the flexuras themselves may act as a ground path between the static platform and the dynamic platform. Additionally, grounding traces may be added to shield high-frequeney lines (e.g., dual pair lines that carry image signáis from an image sensor to an image signal processor). For example, each of the first flexure 1002i and the second flexure 1004 may inelude signal traces 1010Í (e.g., two signal traces, as shown in FIG. 101). Furthermore, one or more common shield traces 1012i may overly the signal traces 101 Oi to shield the signal traces lOlOi. The signal traces 101 Oi and/or the common shield trace 1012Í may be electrically insulated from each other, from the rest of the respective flexure, and/or from other flexuras, via an insulator 1014i. In some cases, a portion having the signal traces 101 Oi, the common shield trace 1012i, and the insulator 1014i may be wider than the underlying portion of the respective flexure, such that at least a portion of the insulator 1014i and/or one or more of the traces 1012i, 1014i extends beyond the width of the underlying portion of the respective flexure.

[00129] In some examples, it may be desirable to selectively choose which traces are placed on different flexures. For example, in instances where one trace and a flexure carries a power signal to the dynamic platform (e.g., to the image sensor and/or OIS control circuitry) and traces on another flexure carry image signáis from the image sensor, it may be desirable to position a ground trace on a flexure between the power-carrying flexure and the signal-carrying flexure. For instance, the third flexure 1006i may inelude a ground trace 1016i, and the fourth flexure 1008i may inelude a power trace 1018i. The third flexure 1006i (which ineludes the ground trace 1016i) may be positioned between the second flexure 1004i (which may carry image signáis vía the signal traces 1010Í) and the fourth flexure 1008i (which may carry power vía the power trace 1008i). In some cases, the ground trace 1016i may be a reference different from the grounding of the OIS frame itself. Additionally, in some instances it may be desirable to route one or more power traces along the shortest flexure on the OIS frame. Similarly, image-carrying traces may also be prioritized for shorter flexures, while other traces (e.g., carrying Information between the OIS frame and the axial motion (autofocus) voice coil motor (VCM) actuator) may have longer trace lengths.

[00130] FIG. 10J illustrates a top view of a flexure configuration lOOOj, in accordance with some embodiments. The flexure configuration lOOOj may inelude a flexure 1002j that routes a signal trace 1004j and a shield trace 1006j from a dynamic platform 1008j to a static platform lOlOj. The signal trace 1004j and/or the shield trace 1006j may be electrically connected to the OIS frame at one or more points along the dynamic platform 1008j, the static platform lOlOj, and/or the flexure 1002j. As illustrated in FIG. 10J, in some embodiments the signal trace 1004j and the shield trace 1006 may follow different paths on the dynamic platform 1008j and the static platform lOlOj to allow the shield trace 1006 to electrically connect to the dynamic platform 1008j and the static platform lOlOj, e.g., using vías 1012j.

[00131] In various embodiments, one or more of the flexure stabilizer members described herein (e.g., with reference to FIGS. 8A-9L and 11A-12B) may have cross-sections that are similar to, or identical to, one or more of the flexures described herein (e.g., with reference to FIGS. 10A-10J).

[00132] FIGS. 11 A-l IB each illustrate a view of an example flexure module 1100 of a voice coil motor (VCM) actuator that may be used, for example, in a camera (e.g., the cameras described above with reference to FIGS. 1-5) to provide optical image stabilization, in accordance with some embodiments. FIG. 11A illustrates a top view of the flexure module 1100. FIG. 11B illustrates a perspective view of the flexure module 1100. Electrical traces may be routed from a dynamic platform 1102 to a static platform 1104 vía flexures 1106 and/or flexure stabilizer members 1108, e.g., as described above with reference to FIGS. 10A-10J. In some examples, the electrical traces may be routed, via one or more flexures 1106 and/or one or more flexure stabilizer members 1108, from one or more electrical connection elements 1110 disposed on the dynamic platform 1102 to one or more electrical connection elements 1112 disposed on the static platform 1112.

[00133] The electrical connection elements 1110 may be disposed along one or more portions (or sides), of the dynamic platform 1102. For instance, the electrical connection elements 1110 may be disposed along one or more flexure roots at which the flexures 1106 connect to the dynamic platform 1102. Likewise, the electrical connection elements 1112 may be disposed along one or more portions (or sides) of the static platform 1104. For instance, the electrical connection elements 1112 may be disposed along one or more flexure roots at which the flexures 1106 connect to the static platform 1104. In some examples, the electrical connection elements 1110 may be configured to electrically couple with an image sensor and/or another component (e.g., a flip chip, a substrate, etc.) that is coupled to the image sensor. Accordingly, the dynamic platform 1102 may be configured to receive signáis (e.g., image signáis) from the image sensor via the electrical connection elements 1110, and the signáis may be conveyed from the electrical connection elements 1110 of the dynamic platform 1102 to the electrical connection elements 1112 of the static platform 1104 via one or more electrical traces routed along the flexures 1106 and/or the flexure stabilizer members 1108.

[00134] In FIGS. 11A and 11B, the electrical connection elements 1112 are located on a common side of the static platform 1104. However, electrical connection elements may be on múltiple sides of the static platform in some embodiments. For example, FIG. 7A shows electrical connection elements on two different sides of the static platform.

[00135] In some embodiments, when there are electrical traces on both sides of a flexure 1106 (e.g., as indicated in FIG. 10E), there may be vías through the dynamic platform 1102 so that electrical connection elements 1110 are on a common side of the dynamic platform 1102. For the static platform, electrical traces may be brought up to a common surface using vías (e.g., to facilítate ease of connection) or may be on different surfaces (which can facilítate reduction in the size of the OIS frame in some cases).

[00136] FIGS. 12A-12B each illustrate a view of a flexure module 1200 of a voice coil motor (VCM) actuator that may be used, for example, in a camera e.g., the cameras described above with reference to FIGS. 1-5) to provide optical image stabilization, in accordance with some embodiments. FIG. 12A illustrates a top view of the flexure module 1200. FIG. 12B illustrates a perspective view of the flexure module 1200. The flexure module 1200 may inelude one or more flex circuits 1202 configured to route one or more electrical traces 1204 from a dynamic platform 1206 to a static platform 1208.

[00137] In some examples, the electrical traces 1204 may be routed, via one or more flex circuits 1202, from one or more electrical connection elements 1210 disposed on the dynamic platform 1206 to one or more electrical connection elements 1212 disposed on the static platform 1208.

[00138] The electrical connection elements 1210 may be disposed along one or more portions (or sides), of the dynamic platform 1206. Likewise, the electrical connection elements 1212 may be disposed along one or more portions (or sides) of the static platform 1208. In some examples, the electrical connection elements 1210 may be configurad to electrically couple with an image sensor and/or another component (e.g., a flip chip, a substrate, etc.) that is coupled to the image sensor. Accordingly, the dynamic platform 1206 may be configurad to receive signáis (e.g., image signáis) from the image sensor via the electrical connection elements 1210, and the signáis may be conveyed from the electrical connection elements 1210 of the dynamic platform 1206 to the electrical connection elements 1212 of the static platform 1208 via one or more electrical traces 1204 routed along one or more flex circuits 1202.

[00139] In some embodiments, a flex circuit 1202 may inelude a first end that is fixed (e.g., via an adhesive) to the dynamic platform 1206, a second end that is fixed (e.g., via an adhesive) to the static platform 1208, and a middle portion between the first end and the second end. The second end of the flex circuit 1202 may be opposite the first end of the flex circuit 1202. Furthermore, in some embodiments, the middle portion of the flex circuit 1202 may inelude an amount of slack that facilitates relative movement between the first and second ends of the flex circuit 1202. The amount of slack may be determined based at least in part on a stifíhess of the flexure module 1200. Moreover, in various embodiments, the flex circuits 1202 may inelude a flexible material. In some embodiments, múltiple flex circuits 1202 may be disposed in proximity with one another to form a flex circuit array.

[00140] In some examples, in addition to routing electrical traces via one or more flex circuits 1204, the flexure module 1200 may route electrical traces via the flexuras 1214 and/or the flexure stabilizer members 1216, e.g., as described above with reference to FIGS. 11A-11B. [00141] FIG. 13 is a flowehart of an example method 1300 of conveying signáis (e.g., image signáis) from a dynamic platform of a voice coil motor (VCM) actuator to a static platform of a VCM actuator, in accordance with some embodiments.. At 1302, the method 1300 may inelude receiving, at the dynamic platform, one or more signáis. For instance, the signáis may be signáis produced by an image sensor. At 1304a, the method 1300 may inelude conveying the signáis from the dynamic platform to the static platform at least partly via electrical traces routed on/within one or more flexure arms and/or one or more flexure stabilizer members of the VCM actuator, e.g., as described above with reference to FIGS. 11A-11B. Additionally, or altematively, at 1304b, the method 1300 may inelude conveying the signáis from the dynamic platform to the static platform at least partly via electrical traces routed on/within one or more flex circuits of the VCM actuator, e.g., as described above with reference to FIGS. 12A-12B.

In some embodiments, the device is a portable Communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Other portable electronic devices, such as laptops, cameras, cell phones, or tablet computers, may also be used. It should also be understood that, in some embodiments, the device is not a portable Communications device, but is a desktop Computer with a camera. In some embodiments, the device is a gaming Computer with orientation sensors (e.g., orientation sensors in a gaming controller). In other embodiments, the device is not a portable Communications device, but is a camera.

[00143] In the discussion that follows, an electronic device that ineludes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device may inelude one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

[00145] The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding Information displayed on the device may be adj usted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device may support the variety of applications with user interfaces that are intuitive and transparent to the user.

[00146] Attention is now directed toward embodiments of portable devices with cameras. FIG. 14 illustrates a block diagram of an example portable multifunction device that may inelude a camera module (e.g., the cameras described above with reference to FIG. 1-5), in accordance with some embodiments.

[00147] It should be appreciated that device 1400 is only one example of a portable multifunction device, and that device 1400 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in FIG. 14 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

[00148] Memory 1402 may inelude high-speed random access memory and may also inelude non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 1402 by other components of device 1400, such as CPU 1420 and the peripherals interface 1418, may be controlled by memory controller 1422.

[00149] Peripherals interface 1418 can be used to couple input and output peripherals of the device to CPU 1420 and memory 1402. The one or more processors 1420 run or execute various software programs and/or sets of instructions stored in memory 1402 to perform various functions for device 1400 and to process data.

[00150] In some embodiments, peripherals interface 1418, CPU 1420, and memory controller 1422 may be implemented on a single chip, such as chip 1404. In some other embodiments, they may be implemented on sepárate chips.

[00151] RF (radio frequeney) circuitry 1408 receives and sends RF signáis, also called electromagnetic signáis. RF circuitry 1408 converts electrical signáis to/from electromagnetic signáis and communicates with Communications networks and other Communications devices vía the electromagnetic signáis.

[00152] Audio circuitry 1410, speaker 1411, and microphone 1413 provide an audio interface between a user and device 1400. Audio circuitry 1410 receives audio data from peripherals interface 1418, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 1411. Speaker 1411 converts the electrical signal to human-audible sound waves. Audio circuitry 1410 also receives electrical signáis converted by microphone 1413 from sound waves. Audio circuitry 1410 converts the electrical signal to audio data and transmits the audio data to peripherals interface 1418 for processing. Audio data may be retrieved from and/or transmitted to memory 1402 and/or RF circuitry 1408 by peripherals interface 1418. In some embodiments, audio circuitry 1410 also ineludes a headset jack (e.g., 1512, FIG. 15). The headset jack provides an interface between audio circuitry 1410 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

[00153] I/O subsystem 1406 couples input/output peripherals on device 1400, such as touch screen 1412 and other input control devices 1416, to peripherals interface 1418. I/O subsystem 1406 may inelude display controller 1456 and one or more input controllers 1460 for other input or control devices. The one or more input controllers 1460 receive/send electrical signáis from/to other input or control devices 1416. The other input control devices 1416 may inelude physical buttons (e.g., push buttons, rocker buttons, etc.), diais, slider switches, joysticks, click wheels, and so forth. In some altérnate embodiments, input controller(s) 1460 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 1508, FIG. 15) may inelude an up/down button for volume control of speaker 1411 and/or microphone 1413. The one or more buttons may inelude a push button (e.g., 1506, FIG. 15).

[00154] Touch-sensitive display 1412 provides an input interface and an output interface between the device and a user. Display controller 1456 receives and/or sends electrical signáis from/to touch screen 1412. Touch screen 1412 displays visual output to the user. The visual output may inelude graphics, text, icons, video, and any combination thereof (collectively termed "graphics"). In some embodiments, some or all of the visual output may correspond to user-interface objeets.

[00155] Touch screen 1412 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 1412 and display controller 1456 (along with any associated modules and/or sets of instructions in memory 1402) detect contact (and any movement or breaking of the contact) on touch screen 1412 and converts the detected contact into interaction with user-interface objeets (e.g., one or more soñ keys, icons, web pages or images) that are displayed on touch screen 1412. In an example embodiment, a point of contact between touch screen 1412 and the user corresponde to a finger of the user.

[00156] Touch screen 1412 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 1412 and display controller 1456 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 1412. In an example embodiment, projected mutual capacitance sensing technology is used. [00157] Touch screen 1412 may have a video resolution in excess of 800 dpi. In some embodiments, the touch screen has a video resolution of approximately 860 dpi. The user may make contact with touch screen 1412 using any suitable object or appendage, such as a Stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

[00158] In some embodiments, in addition to the touch screen, device 1400 may inelude a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is sepárate from touch screen 1412 or an extensión of the touch-sensitive surface formed by the touch screen.

[00159] Device 1400 also ineludes power system 1462 for powering the various components.

[00160] Device 1400 may also inelude one or more optical sensors or cameras 1464. FIG. 14 shows an optical sensor 1464 coupled to optical sensor controller 1458 in I/O subsystem 1406. Optical sensor 1464 may inelude charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 1464 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 1443 (also called a camera module), optical sensor 1464 may capture still images or video. In some embodiments, an optical sensor 1464 is located on the back of device 1400, opposite touch screen display 1412 on the front of the device, so that the touch screen display 1412 may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

[00161] Device 1400 may also inelude one or more proximity sensors 1466. FIG. 14 shows proximity sensor 1466 coupled to peripherals interface 1418. Altemately, proximity sensor 1466 may be coupled to input controller 1460 in I/O subsystem 1406. In some embodiments, the proximity sensor 1466 tums off and disables touch screen 1412 when the multifunction device 1400 is placed near the user's ear (e.g., when the user is making a phone cali).

[00162] Device 1400 ineludes one or more orientation sensors 1468. In some embodiments, the one or more orientation sensors 1468 inelude one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors 1468 inelude one or more gyroscopes. In some embodiments, the one or more orientation sensors 1468 inelude one or more magnetometers. In some embodiments, the one or more orientation sensors 1468 inelude one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining Information conceming the location and orientation (e.g., portrait or landscape) of device 1400. In some embodiments, the one or more orientation sensors 1468 inelude any combination of orientation/rotation sensors. FIG. 14 shows the one or more orientation sensors 1468 coupled to peripherals interface 1418. Altemately, the one or more orientation sensors 1468 may be coupled to an input controller 1460 in I/O subsystem 1406. In some embodiments, Information is displayed on the touch screen display 1412 in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors 1468.

[00163] In some embodiments, the software components stored in memory 1402 inelude operating system 1426, communication module (or set of instructions) 1428, contact/motion module (or set of instructions) 1430, graphics module (or set of instructions) 1432, text input module (or set of instructions) 1434, Global Positioning System (GPS) module (or set of instructions) 1435, arbiter module 1458 and applications (or sets of instructions) 1436. Furthermore, in some embodiments memory 1402 stores device/global intemal State 1457. Device/global intemal State 1457 ineludes one or more of: active application State, indicating which applications, if any, are currently active; display State, indicating what applications, views or other Information occupy various regions of touch screen display 1412; sensor State, including Information obtained from the device’s various sensors and input control devices 1416; and location Information conceming the device’s location and/or attitude.

[00164] Operating system 1426 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) ineludes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

[00165] Communication module 1428 facilitates communication with other devices over one or more extemal ports 1424 and also ineludes various software components for handling data received by RF circuitry 1408 and/or extemal port 1424. Extemal port 1424 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the extemal port is a multi-pin (e.g., 30-pin) connector.

[00166] Contact/motion module 1430 may detect contact with touch screen 1412 (in conjunction with display controller 1456) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 1430 ineludes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more fingerdragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 1430 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may inelude determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to múltiple simultaneous contacts (e.g., "multitouch"/multiple finger contacts). In some embodiments, contact/motion module 1430 and display controller 1456 detect contact on a touchpad.

[00167] Contact/motion module 1430 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact pattems. Thus, a gesture may be detected by detecting a particular contact pattem. For example, detecting a finger tap gesture ineludes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icón). As another example, detecting a finger swipe gesture on the touch-sensitive surface ineludes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

[00168] Graphics module 1432 ineludes various known software components for rendering and displaying graphics on touch screen 1412 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” ineludes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objeets including soft keys), digital images, videos, animations and the like.

[00169] In some embodiments, graphics module 1432 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 1432 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordínate data and other graphic property data, and then generates screen image data to output to display controller 1456.

[00170] Text input module 1434, which may be a component of graphics module 1432, provides soft keyboards for entering text in various applications (e.g., contacts 1437, e-mail 1440, IM 1441, browser 1447, and any other application that needs text input).

[00171] GPS module 1435 determines the location of the device and provides this information for use in various applications (e.g., to telephone 1438 for use in location-based dialing, to camera 1443 as picture/video metadata, and to applications that provide location-based Services such as weather widgets, local yellow page widgets, and map/navigation widgets).

[00172] Applications 1436 may inelude the following modules (or sets of instructions), or a subset or superset thereof: • contacts module (sometimes called an address book or contact list); • telephone module; • video conferencing module; • e-mail client module; • instant messaging (IM) module; • workout support module; • camera module for still and/or video images; • image management module; • browser module; • calendar module; • widget modules, which may inelude one or more of: weather widget, stocks widget, calculator widget, alarm dock widget, didionary widget, and other widgets obtained by the user, as well as user-created widgets; • widget creator module for making user-created widgets; • search module; • video and music player module, which may be made up of a video player module and a music player module; • notes module; • map module; and/or • online video module.

[00174] Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other Information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as sepárate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory 1402 may store a subset of the modules and data structures identified above. Furthermore, memory 1402 may store additional modules and data structures not described above.

[00175] In some embodiments, device 1400 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 1400, the number of physical input control devices (such as push buttons, diais, and the like) on device 1400 may be reduced.

[00176] The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad inelude navigation between user interfaces.
