You can see all these things at the Beijing Winter Olympics. Some technologies make the Games stand out and help people stay safe during COVID-19.
Driverless helpers
Walking inside Shougang Industrial Park, you can see different kinds of driverless cars. When you feel tired, you can get in a driverless minibus. When you feel hungry, you can buy food from a “driverless car store”. Some driverless cars can even send things to you just like a delivery man (快递员).
Body temperature check
People can wear a thermometer (体温计) on their skin. It looks like a bandage (创可贴). One charge (充电) can work for about ten days. Users can check their body temperature through an app on their smart phones. If someone gets a fever, the thermometer will report it.
Remote interview
Usually after each event, reporters will interview players face to face. To stay safe, the Beijing Winter Olympics will do remote interviews. The reporters can’t meet the players. But they can talk with each other by video.

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
