Analog security cameras are used for video surveillance. These cameras monitor the perimeters of various areas and provide information in the form of images and videos. They are used to oversee spaces of properties such as houses, schools, retail shops, banks, restaurants, airports, parking spaces, hospitals, streets, parks, rivers, traffic junctions, and squares. An analog security camera records the captured content on a digital video recorder (DVR) and also can be connected directly to a regular television (TV) or monitor.

A phacoemulsification device is an ultrasonic equipment that has been accepted as the gold standard for cataract surgical procedures. It is a mechanically assisted extracapsular technique used for cataract extraction. Phacoemulsification is a common indication performed during cataract surgery and enables easy implantation of IOL in the posterior chamber. Using this device, the cataract is extracted through a 3.0 millimeters (mm) incision. The ultrasound waves break the cataract into smaller pieces and allow a small incision. Phacoemulsification helps in significantly shortening the recovery period and involves lesser pain when compared with conventional cataract procedures. It also conserves the posterior chamber, and vitreous body and avoids retinal detachment

Bluetooth headphones are wireless audio devices that use bluetooth technology to connect to audio sources like smartphones, tablets, laptops, and other devices. They allow users to listen to audio content without being tethered by wires.

Aesthetic lasers are non-surgical, non-invasive procedures that are safe and effective for most skin types and skin tones. It involves the utilization of specific wavelengths of light to target and treat various skin concerns, such as wrinkles, scars, pigmentation issues, hair removal, and tattoo removal. Aesthetic lasers are designed to deliver controlled and precise energy to the skin, promoting collagen production and skin rejuvenation, resulting in improved skin texture and appearance

A laptop is a small-sized mobile PC with a thin LED or LCD screen and an alphanumeric keyboard. Laptops are generally used for a variety of purposes, such as work, education, multimedia consumption, Internet surfing, and gaming. Based on type, the market has been segmented into traditional and 2-in-1 laptops. A traditional laptop is generally in the form of a clamshell, with a keyboard and a screen facing each other on the inner sides. 2-in-1 laptops integrate the capabilities of a laptop and tablet into one device and are often equipped with energy-efficient processors and a large number of ports.

Holter monitors are battery-operated portable devices that measure and record the heart’s activity continuously for 24 to 48 hours or a month or longer depending on the patient’s condition.

Fetal Doppler is a critical tool in prenatal care, revolutionizing the way healthcare professionals monitor the health and wellbeing of unborn babies. This non-invasive diagnostic technique uses the Doppler effect to measure and assess blood flow within fetal vessels, providing essential information about the fetal heart rate and overall cardiovascular health.

12 月 15 日，国家发改委研究起草了《“数据要素×”三年行动计划（2024—2026 年）（征求意见稿）》，提出要将 2026 年底数据产业年均增速超过 20%，数据交易规模增长 1 倍设为总体目标，并就数据要素在各行业的拓展行动做出规划。实施“数据要素×”行动，推动数据在多样场景中发挥乘数效应。《征求意见稿》提到，近年来国内数据发展存在场景释放不够的问题，数据具有规模报酬递增、非竞争性、低成本复用的特点，作用于不同的主体与不同的要素结合，可产生不同程度的倍增效应。因此《征求意见稿》 中将通过实施“数据要素×”行动推动数据在不同场景中发挥乘数效应，其重点行动共包含了数据要素×智能制造，气象服务，智慧城市，绿色低碳等 12 个领域，积极转化数据基础资源优势为经济发展新优势，推动数据要素价值创造的新业态成为经济增长新动力。
