Abstract
A suspension assembly is described. The suspension assembly including a static member or plate; a moving member or plate movable about an x-axis and a y-axis with respect to the static plate; a sensor mounting region on the moving plate; and one or more shape memory alloy (SMA) elements extending between and coupled to the static plate and moving plate. The SMA elements, when driven by a controller, move the moving plate and the sensor mounting region thereon about the x-axis and the y-axis with respect to the static plate.
Claims32
A suspension assembly comprising:
- a static plate;
- a moving plate movable about an x-axis and a y-axis with respect to the static plate;
- a sensor mounting region of the moving plate that is unitary with the moving plate, the moving plate configured to shift the sensor mounting region with respect to one or more lens;
- and
- a plurality of shape memory alloy (SMA) elements extending between and coupled with the static plate and moving plate, the SMA elements are configured to move the moving plate when driven by a controller and the sensor mounting region thereon about the x-axis and the y-axis with respect to the static plate.
