ACTUATOR FOR CAMERA AND CAMERA MODULE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18337675 titled 'ACTUATOR FOR CAMERA AND CAMERA MODULE INCLUDING THE SAME
The actuator described in the patent application consists of a base with three moving frames stacked on top. An image sensor is mounted on the first moving frame, and each moving frame is driven by shape memory alloy wires through sensor driving portions.
- The actuator includes a base and three moving frames stacked on top.
- An image sensor is mounted on the first moving frame.
- Shape memory alloy wires are used to drive each moving frame through sensor driving portions.
- The first sensor driving portion moves the first frame in a perpendicular direction to the optical axis.
- The second sensor driving portion moves the second frame in a direction perpendicular to the first direction.
- The third sensor driving portion rotates the third frame based on the optical axis.
Potential Applications: - Robotics - Camera stabilization systems - Medical devices - Automotive technology
Problems Solved: - Precise control of movement in multiple directions - Compact design for space-constrained applications - Efficient energy usage with shape memory alloy wires
Benefits: - Improved accuracy in positioning - Versatile movement capabilities - Energy-efficient operation
Commercial Applications: Title: Innovative Actuator Technology for Precision Control Systems This technology can be used in various industries such as robotics, photography, healthcare, and automotive for precise movement and control systems.
Questions about the technology: 1. How does the use of shape memory alloy wires improve the actuator's performance? 2. What are the potential limitations of this actuator technology in real-world applications?
Original Abstract Submitted
An actuator includes: a base; first, second, and third moving frames stacked on the base; an image sensor mounted on the first moving frame; a first sensor driving portion including first frame driving members and first shape memory alloy wires disposed outside an edge of the first moving frame to drive the first moving frame in a first direction perpendicular to the optical axis; a second sensor driving portion including second frame driving members and second shape memory alloy wires disposed outside an edge of the second moving frame to drive the second moving frame in a second direction perpendicular to the first direction; and a third sensor driving portion including third frame driving members and third shape memory alloy wires disposed outside an edge of the third moving frame to rotatably drive the third moving frame based on the optical axis.
