An ultrasonic sensor works by releasing sound waves at high frequency for humans to hear, and when sound is reflected, it calculates the distance based on the time it took to travel. It is widely used in many applications such as presence detection, stacking height control, robotic sensing, liquid level control, loop control, full detection, through-beam detection for high-speed counting, irregular parts detection for hoppers and feeder bowls, 45° deflection, thread or wire break detection, and contouring using ultrasonic systems.

The ultrasound devices market is segmented into product type, type of device display, device portability, application, and region. By product type, it is segmented into diagnostic ultrasound systems (including 2D imaging systems, 3D & 4D imaging systems, and Doppler imaging), and therapeutic ultrasound systems (including HIFU and ESWL). By type of device display, it is bifurcated into color ultrasound devices and B/W ultrasound devices. By device portability, it is divided into trolley/cart-based ultrasound devices and compact/handheld ultrasound devices. Ultrasound technology finds applications in many clinical areas, namely, radiology/general imaging, cardiology, obstetrics/gynecology, vascular, urology, and other clinical areas such as emergency medicines, anesthesiology, and musculoskeletal.

以“迈向数字文明新时代——携手构建网络空间命运共同体”为主题的2021年世界互联网大会乌镇峰会于9月26日至28日在浙江乌镇召开，将探讨网络空间发展治理等诸多议题。不久前，中国互联网络信息中心发布的《中国互联网络发展状况统计报告》显示，截至今年6月份，中国网民规模达10.11亿，形成了全球最为庞大的数字社会。全“数”前进的中国，正用一系列数字汇聚经济发展的澎湃伟力。“中国高质量数字经济发展为破解人类共同挑战提供了可行方案。”中国国际经济交流中心总经济师陈文玲表示，今年上半年，互联网进一步发挥支撑引领作用，成为未来产业的核心引擎和构建新发展格局的重要力量。

Smart display is a digital screen designed to use around the home, retail, and automotive sectors for digital communication, which sometimes also includes a sizable touch screen. Further, the home display devices can be for more than just control but support entertainment, video chats, information videos, and control other smart applications inside homes. Smart display is popular for use in the retail sectors for digital communication and can be programmed, scheduled as per user preferences, especially with set daily routines to display images and videos information. Moreover, smart display application such as home display has advance features such as Bluetooth speaker with screen to make it more user friendly. These devices can be easily installed by consumers and are compatible with wide range of smart electronic appliances.
