A long positioning range and a high first natural frequency are the two most important quality
responses of a compliant focus positioning platform (CFPP). This paper aims to develop a …

Abstract The Unmanned Aerial Vehicle (UAV) video system uses a portable camera
mounted on the robot to monitor scene activities. In general, UAVs have very little …

Piezoelectric actuators are widely used in the optical field due to their high precision,
compact structure, flexible design, and fast response. This paper presents a novel …

In this paper, we report an actuator with a magnet made of novel rare earth magnetic powder
Sm-Fe-N with diameter of 2 µm to 5 µm. Micro magnets were fabricated by mixing the …

In the application of cell phone cameras, it is essential to design optical image stabilizers
with tiny size, in-plane motion and large stroke. Previously, small sized voice-coil actuators …

Feature phones or low-end smart phones are an important part of our daily life. While
lacking the powerful embedded camera and processing capability of the high-end smart …

This paper presents uncertainty modeling and robust controller design for 3 degrees-of-
freedom miniaturized optical image stabilizers (OISs) against product variabilities. To …

This study proposes a novel concept of actuator-driven frame-by-frame intermittent tracking
for motion-blur-free video shooting of fast-moving objects. The camera frame and shutter …

Owing to the fourth industrial revolution and the recent trend for compact, high-performance,
and multifunctional electrical devices, the demand for a small and high-performance camera …

This paper presents robust control of large-scale prototypes for miniaturized optical image
stabilizers (OIS's) with product variations. Based on the conceptual design of a miniaturized …
