Interesting and unusual gadgets CES 2023

LG’s Transparent TV Screen
LG’s transparent TV screen is not so much about the TV, but about the future of technology. For example, LG already offers transparent screens in the form of doors for shopping centers or walls.

Commercially, it looks like this. The TV is transparent, but it shows an image with a brightness of 400 nits.
When an image is on the screen, the TV no longer appears transparent. It is clear that you do not need such a thing for 6 thousand euros at home. But it will definitely find a use in shopping centers and offices. For example, in a conference room, such a screen would be more than appropriate. You can put it in the middle of the table without fear of blocking someone.

Above were the examples of previous years. This year, LG has gone a little further. The televisions do not look transparent when playing content. At the same time, the TVs can act as an element of the interior.

SF (Super Fast) Battery.
The Super Fast Battery for electric cars is based on a cathode with an 83% nickel content and using SK On’s proprietary charging protocol, the battery can charge from 10% to 80% in 18 minutes, giving, according to the company, a range of 400 km. The technology is not considered as something fundamentally new. The innovation here is that previously such batteries were easy to catch fire. Accordingly, they were not allowed in cars. The SK company claims that it managed to solve the problem. And now this battery is already being used on Hyundai IONIQ 5 and KIA EV6. Both cars belong to the medium-affordable price segment, which can not but rejoice. Unfortunately, the company did not say anything about the durability of such batteries.

Alphabeats
There have always been a lot of health-related gadgets, but this year there is an obscene amount of them. However, before, such gadgets were primarily simple measuring devices capable of transmitting data via Bluetooth to a device where some basic analysis took place. Now we see attempts to interact directly with the user in real time. As an example, let’s talk about Alphabeats. The idea is that the headband tries to measure brain waves (electroencephalogram) and regulate them with music. For example, aggressive music in a workout, for example, is formally thought to promote more energetic and focused exercise. But perhaps your brain responds better to other music. Likewise with music for relaxation. That is, Alphabeats tries to select music to which a particular user’s brain responds better.

It may seem like some knee-jerk nonsense (as, however, most of the innovations related to “digital health”), but the company has been around for several years. The work of the idea is confirmed by a study, which was conducted at a university for 4 years. It would be more accurate to say that the confirmed research was the impetus for the creation of the company.

Again, I want to emphasize that Alphabeats is an example of technology that interacts and adjusts in real time. Right now it is more common to have fitness bracelets that work on the principle of collecting information. The user looks: this is how you slept, this is how you ran, this is your heart rate throughout the day. The new generation, on the other hand, is aimed at adjustments and results in real time.

Noise-canceling headphones with built-in air purifier ible Airvida T1
Sounds like complete nonsense, of course, but curious nonetheless!
About the operation of the noise cancelling headphones, I think there is no question. Much more interesting is the mechanism of personal air purification. So, the headphones have built-in sensors that evaluate the amount of PM 2.5 particles. To clean the headphones release negatively charged ions: increases the number of negative ions that gather around the face area, up to 3 million/cm3 every 0.6 seconds. The same amount of negatively charged ions is generated by 300 trees (I don’t know why the manufacturer gives this information!). Under the influence of negatively charged ions, PM 2.5 particles stick together, become large, heavy, and fall down. The makers swear that the device removes 99.9% of allergens and viruses that dance in your face.
