Abstract: A novel high resolution, low noise MEMS capacitive accelerometer is disclosed. The accelerometer utilizes a piston-tube electrode configuration that enables the use of a wide area for the electrodes. Therefore, a high capacitive sensitivity is achieved. The accelerometer consists of two structures: upper and lower. The lower structure contains a plurality of fixed electrodes that are attached to the base and have a piston-style shape (teeth). Those pistons form the sensing electrodes of the accelerometer. The upper structure contains a plurality of moving electrodes that have a tube-style shape (through holes), and they are attached to a substrate via restoring mechanical springs. The proof mass of the accelerometer is distributed around these tubes to reduce squeeze thin film damping in the system. The accelerometer is able to sense linear acceleration along the z-axis and/or the angular acceleration about the in-plane axes (x and y).

Abstract: Miniature camera modules that achieve autofocus (AF) and optical image stabilization (OIS) using piston-tube electrostatic actuators are disclosed. Various embodiments of the camera modules that work on two main mechanisms are disclosed. The two mechanisms are the whole barrel motion leading to AF and OIS and the single lens motion leading to AF. The MEMS actuator is integrated within a housing which is, in turn, coupled with an image sensor module. Autofocus is achieved by a translational motion of the piston-tube electrostatic actuator to translate the whole barrel back and forth. OIS is achieved by tilting the whole barrel using the tilting action of the piston-tube actuator.

Abstract: The present invention is a mechanism to achieve autofocus (AF) and optical image stabilization (OIS) to counteract hand-shake by tilting the lens and the image sensor simultaneously such that no vignetting effect is introduced to the image. The present invention removes the blur or distortion (vignetting effect) by incorporating an actuator beneath the image sensor to tilt the image sensor in conjunction with the lens barrel tilt to achieve OIS. Such simultaneous and coordinated tilting to the optical elements in the camera (lens barrel and image sensor) guarantees that the plane of the reflected image and the plane of the image sensor are both parallel, and aberrations free images are constructed.
