Some of the units I've seen up close were asleep, with the robotic eye gently nodding, as if it were breathing. One was tracking the crowd and answering questions, responding either with a nod or a shake.，详情可参考PDF资料
Once he invests, Zeplain operates differently than most VCs. He won’t, under any circumstances, take board seats. He’d rather hear whole stories, not the versions sanitized for a boardroom. His conversations with founders tend to be less about strategy and more about clarity—helping entrepreneurs think through what they’re actually seeing, rather than telling them what to do. The coaching is business-oriented, but it’s fundamentally psychological.。关于这个话题，谷歌浏览器下载提供了深入分析

A few years ago, Cornman found a way around the problem. In the U.S., commercial flights served by air-traffic control—some twenty-seven thousand a day—are required to transmit their position, altitude, and velocity. By tracking those transmissions and the planes’ motions over time, a new program that Cornman developed at NCAR can create a moment-by-moment snapshot of turbulence as it’s happening. The F.A.A. is planning to test the program this year. Together with NCAR’s earlier software, Sharman’s forecasting models, and data from radar arrays on the ground, this system could start to give pilots the advance warning they need. “That is the future for me,” Cornman said. “All these operations get integrated in a seamless network. The pilots don’t have to talk to air-traffic control and say, ‘Should I go up or down?’ They just get a display with a color-coded flight track on it. And they see that it looks better a few thousand feet up.”
