Transponders receive an electromagnetic or radiofrequency signal from the Earth, amplify it, and send it back to Earth. Transponders are designed to exhibit various functionalities and they work based on a particular frequency band like C, Ku, and Ka. Depending on the signal strength and encoding/decoding techniques used for transmission and reception, a transponder can change the frequency, polarization, and modulation technique for signal regeneration, amplification, and retransmission back to Earth. The speed and centrifugal force of the satellite depend on the distance from the Earth's orbit. The speed and the gravitational pull of the satellite orbiting closer to Earth are higher than the ones that are orbiting farther. Different satellites placed in different orbits require transponders as per their band spectrum such as C, Ku, and Ka, for various communication and broadcasting purposes.

Motorcycle adaptive cruise control mechanisms are electronic components that monitor motorcycle speed by controlling engine RPM to maintain a constant set speed. The adaptive cruise control is made up of three main components: servo unit, throttle cable, and the associated wiring. An adaptive cruise control uses the speed signal from vehicle speed sensor in case of electronic speedometers, or monitor engine RPM through electrical connections made to the ignition coil. When adaptive cruise control is engaged by pressing the “set” button at a desired speed, it will set that speed such that the motorcycle will travel at the set speed consistently, until the adaptive cruise control mechanism is disengaged. Adaptive cruise control can be disengaged both automatically and manually. The mechanism disengages automatically when front or rear brakes are applied, or when the clutch is disengaged by the rider. The control can be manually disengaged by simply turning off the switch. The consistent speed allows the engine to burn fuel efficiently and gives the rider comfort and control over set speed limits.

Flow meters measure the mass, quantity, pressure and velocity of any fluid or gas flowing through a pipeline. These meters are classified into two types: Analog flow meters Smart/intelligent flow meters At present, the majority of the flow meters used are traditional analog flow meters, which are used to measure the flow of the fluid (oil and water) and gas (LPG, NG, condensate). But the trend is shifting toward the adoption of smart meter technology. Various governments and companies are adopting these new smart meters, which can transmit real-time data about consumption, peak load, and other crucial information such as leakages that need to be addressed immediately.

分立器件是半导体的重要分支，2015 年全球分立器件销售额达607 亿美元，占半导体份额约18%。而功率器件是分立器件的重要部分，纯电动汽车半导体元器件用量达到673 美元，较于传统汽车增加了127%。而其中功率器件占到新能源汽车中半导体用量的50%。由于新能源汽车等新兴需求的驱动，正迎来发展的黄金时期，百亿空间可期。且半导体中，功率器件对先进制程的依赖度较低，该领域大陆与全球的差距较小，易于实现赶超。

全球打印设备市场近几年的增长连续低迷，2015 年出货量约为 1.04 亿台，比 2014 年微跌 1%。预计未来全球仍将保持小幅微跌的状态。而中国打印机市场连续三年规模呈逐年上升之势， 2014 年达 505.24 亿元，年复合增长率 9.28%，市场表现良性，而耗材市场如出一辙。激光打印机是未来主要增量产品：在成本控制需求提升的背景下，激光复合打印机需求逆势上涨， 2015 年全球激光复合一体机出货量约为 2000 万台，未来四年激光复合一体机的复合年均增长率约为 4.9%。

2016 年9 月15 日22 时04 分,搭载着天宫二号空间实验室的长征二号F T2 运载火箭在酒泉卫星发射中心点火发射。约575 秒后,天宫二号与火箭成功分离,进入预定轨道,发射取得圆满成功，这标志着中国航天事业向前迈进了一大步，中国再次在全世界面前展示出“太空强国”的实力。
