(Original title: There are new tricks beyond the fingerprint brush face: the researchers are developing a fist to unlock)
[TechWeb Report] April 25 news, according to foreign media reports, R & D personnel at Tohoku University in Japan is developing a new system for personal identification through the still image of a fist. Only persons who have previously registered their identity information can unlock it by holding the door handle.
According to foreign media, compared with passwords and fingerprint authentication, the unlocking process is greatly simplified and it is expected that this research and development will be applicable to new security systems.
The mechanism of the new system is roughly as follows: Install a small camera above the door handle, configure the chip for control on the door, or achieve remote control through signal transmission.
According to reports, after converting the image information of the third joint of the index finger, middle finger, ring finger and little finger into a number through mathematical processing, different people will have different numbers, and the system can accurately distinguish these numbers.
The accuracy rate of the currently developed system is 97.64%. Although it is lower than the actual fingerprint and palm authentication system (about 100%), the researchers believe that in the future, improvements can be made to put it into practical use.

There are a few different types of slip rings, but the most common type is called a cap slip ring. Cap slip rings have a cylindrical housing with an internal flange that fits over the end of the shaft. They typically have 6 or 12 channels and are available in a wide range of sizes.
Cap slip rings are used to provide electrical power and signals to and from rotating equipment. The channels on the slip ring allow for the passage of current and/or data signals through the ring. This allows for the rotation of devices such as antennae, radar dishes, and wind turbines without having to interrupt or disconnect the power or signal lines.
Cap slip rings are very reliable and can handle high speeds and heavy loads. They are also easy to install and maintain.
In the modern world, companies are always looking for ways to improve the efficiency of their machines and operations.
