August Wi-Fi Smart Lock
It’ s an intelligent door lock to protect your home, and it works on Wi-Fi. The lock doesn’t require any additional hardware to attach to it and can be used with the existing door lock. The owner can remotely access the door from anywhere to lock or unlock and can provide guest keys to family or friends. It keeps statistics and records of your door’s locks, unlocks, and who have visited.
Motion Pillow
It’s a pillow developed for anyone who has a snoring（打鼾）problem. The solution box detects, records, and analyses the sleeping person’ s snoring patterns. By changing the internal airbag’ s pressure, it fixes the position of the sleeping person’ s neck and head gently to improve their breathing. Three layers of noise-reducing material minimize the user’ s sleeping disturbance.
Aō Air
It’s a high-tech face-covering wearable air purifier with no tight seal on the mouth and nose. The purifier pulls air inside through a filtration（过滤）process and uses fans to create a clean area in front of the device. It’s designed in such a way that it can clean more than 98% of PM2.5 through filtration.
Transparent Hood
The company Continental showed off this revolutionary invention at CES 2020 that got the Best Vehicle Intelligence and Transportation Award. It’ s a technology that gives the driver the ability to see barriers and blind spots from the driving seat.
