Abstract: The present application is directed to a MEMS device. The MEMS device includes a substrate having a first end and a second end extending along a longitudinal axis, the substrate including an electrostatic actuator. The device also includes a movable plate having a first end and a second end. The device also includes a thermal actuator having a first end coupled to the first end of the substrate and a second end coupled to the first end of the plate. The actuator moves the plate in relation to the substrate. Further, the device includes a power source electrically coupled to the thermal actuator and the substrate. The application is also directed to a method for operating a MEMS device.

Abstract: A system and method to convert a CIF compressed video to a QCIF video bitstream provides compatibility between the various digital video sources and application uses. A coding mode and a motion vector for a macroblock in a QCIF video sequence are selected from those of a corresponding CIF video sequence without motion estimation.

Abstract: A composite image generator for generating a multi-image composite from a plurality of individual compressed images is disclosed. Multi-image composites are generated from static images or from a video stream with significantly reduced computation, reduced latency for video processing and reduced storage requirements. The individual images may be compressed with a JPEG image encoder or another suitable intraframe image encoder, such as those implementing the MPEG-II standard. In the illustrative embodiment, four (4) individual images of equal size, compressed using the JPEG standard, are combined into a multi-image composite with a single individual image in each quadrant of the composite image. Multi-image composites are created without fully decoding each individual compressed image, by partially decoding the individual compressed images and only fully decoding a small portion of each image.
