Abstract: A harmonic-suppressing AC/DC power converter employs a control method for permitting the AC/DC power converter only to detect an input AC current and an output DC voltage. The control method can control the AC side of the AC/DC power converter to generate a voltage which is proportional to the input AC current. Thereby, the AC/DC power converter acts as a virtual resistor having a linear resistance characteristic. Accordingly, the input AC current of the AC/DC power converter can be controlled to approximate nearly as a sinusoidal wave with the performance of high input power factor and low input harmonic current.

Abstract: With an image-based rendering (IBR) system based on linear interpolated concentric mosaics, an observer is able to wander through a real or synthesized scene and have new view images (optionally including stereo images) of the scene rendered as the observer moves. According to one embodiment, multiple viewing rays are extended in a viewing direction from the image to be rendered at a view point. For viewing rays that do not coincide with captured images, an image is generated based on the captured images. The image is generated by interpolating between at least two captured images based on a constant distance to objects in the scene. The view images that are displayed can be mono or stereo (e.g., simulating a pair of eyes of the observer).

Abstract: A micro pump using a ferro-fluid/magneto-rheological fluid to drive a working fluid is proposed. The micro pump has a body with an accommodating space and an opening that communicates with the accommodating space. A ferro-fluid/magneto-rheological fluid and a magnetic field generating unit are disposed on the body. As the ferro-fluid/magneto-rheological fluid is attracted to the magnetic field after being magnetized, the ferro-fluid/magneto-rheological fluid is deformed or shifted to drive the working fluid, so as to control the working fluid to flow in and out of the accommodating space. Accordingly, the pump is improved for its efficiency and precision to control the flow while the back flow of the working fluid is prevented.
