Carnegie Mellon University President Farnam Jahanian joined President Joe Biden today for the signing into law of the CHIPS and Science Act of 2022. The CHIPS Act is a $280 billion package aimed at boosting semiconductor manufacturing in the U.S. and improving competitiveness with China. The Act also provides tens of billions of dollars to fund scientific research and development, and to spur the innovation and development of other U.S. technology.

卡耐基梅隆大学的研究人员开发了一个摄像系统，可以以极其精确和细致的方式观察声音震动，甚至可以重建乐队或者管乐队里单个乐器的声音。
即便是最高功率和定向的麦克风也无法在捕获音频时消除附近的声音、环境噪音和声学影响。计算机科学学院机器人研究所开发的新系统使用两个摄像头和一个激光来感知高速、低振幅的表面振动。这些振动可以用于重建声音，无需推断或者麦克风就可以捕获单独的孤立音频。

A camera system developed by Carnegie Mellon University researchers can see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra.
Even the most high-powered and directed microphones can't eliminate nearby sounds, ambient noise and the effect of acoustics when they capture audio. The novel system developed in the School of Computer Science's Robotics Institute (RI) uses two cameras and a laser to sense high-speed, low-amplitude surface vibrations. These vibrations can be used to reconstruct sound, capturing isolated audio without inference or a microphone.
