A | 1月11日，据外国媒体报道，美国商标专利局（USPTO）最近曝光了联想的笔记本电脑，该电脑配备了灵活的可折叠显示屏，能够运行Windows10操作系统，该系统也采用虚拟键盘设计。 (ECNS) -- Researchers at The University of Hong Kong (HKU) have developed a minimalist analogue content-addressable memory (CAM) chip that performs complex searches directly where data are stored, the university said Tuesday. When tasked with calculating the analogue Hamming distance for machine learning classification, the new analogue CAM performed the task approximately 108 (100 million) times faster than a standard CPU, scoring exceptionally high accuracy across multiple datasets, according to the university. The chip is designed to reduce the slow and energy-intensive transfer of data between memory and processors, known as the “von Neumann bottleneck.” Its architecture can compare incoming search data with all stored data simultaneously in a single step. Led by professor Li Can from the Department of Electrical and Computer Engineering of the Faculty of Engineering and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC), the team built each analogue CAM cell with just two transistors, compared with up to 16 in a conventional digital CAM cell. The design reduces chip area and allows continuous analogue signals to be processed directly. Li said the team is exploring how the technology could support search mechanisms in large AI models. The findings were published in Nature Nanotechnology. (By Intern Yang Hongran, Zhang Dongfang) 
。联想的专利名称是“可折叠显示屏设备”。联想的专利于2017年6月申请，直到2019年1月10日美国专利局才发布。根据专利信息，联想的计算设备一边有屏幕和外壳，另一边有键盘和外壳。
B | 两侧通过铰链部件连接在一起，折叠后可分为不同的使用区域。处理器、内存和虚拟键盘分布在外壳的两侧。接收时，位于两侧的柔性显示屏可以自然卷曲和折叠。尽管专利的曝光并不意味着相关产品很快就会上市，但它至少为未来增加了一个有趣的可能性。在今年的CES上，许多制造商都展示了类似的柔性折叠屏幕设备。
