| 技術摘要 / Our Technology： |
本發明揭示了一種聚氨基甲酸酯(Polyurethane,PU)複合材料，其係由一熱塑性聚氨基甲酸酯(Thermoplastic Polyurethane,TPU)與一填充料混合而成。上述之熱塑性聚氨基甲酸酯包含一線性聚氨基甲酸酯主鏈，此聚氨基甲酸酯主鏈更包含一硬鏈段與一軟鏈段，其中，硬鏈段係藉由一雙異氰酸酯(Diisocyanate)和鏈延伸劑(chain extender)反應形成，而軟鏈段係由聚醇(polyol)所形成。另一方面，上述之聚氨基甲酸酯複合材料可應用於根管封填材料。
Video communication systems and methods for communicating between an individual in a local environment, and a remote viewer in a remote environment are provided. The system has an image display device; at least one image capture device which acquires video images for fields of view of a local environment, and any individuals therein; an audio system having an audio emission device and an audio capture device; a computer, which includes a contextual interface having a gaze adapting process, and image processor; and a communication controller which transmits and receives video images of the local environment and the remote environment, and data regarding video scene characteristics thereof across a network between the local environment and the remote environment; wherein the gaze adapting process identifies video scene characteristics of the local environment indicative of eye gaze image capture and altering the video images when the characteristics are indicative.
