What is iris recognition and iris attendance?

Iris recognition/retina recognition is a technique that generates less interference with people in eye-related biometrics. It uses a fairly common camera element and does not require the user to come into contact with the machine. In addition, it has the ability to achieve higher template matching performance. Therefore, it attracted the attention of various people. Among all biometric technologies, iris/retina recognition is the most convenient and accurate one for current applications. The 21st century is the century of information technology and network technology. It is also a century in which mankind has been freed from the traditional technological constraints and has become more and more free.

In this century characterized by information and freedom, biometric authentication technology, as a high and new technology that has only begun to flourish in the late 20th century, is bound to occupy an increasingly important position in social life, fundamentally changing the human lifestyle. . The characteristics of the human body such as iris/retina, fingerprint and DNA will gradually replace existing passwords, keys, and lifestyles that people are accustomed to. At the same time, it will ensure the security of personal data to the maximum extent and prevent all types of criminals to the maximum extent possible. Economic crime activities.

Iris attendance is based on the iris recognition technology used in security access control systems. With the development of iris recognition technology, iris attendance will be the most popular and most popular technology in China's security access control market.

If you need to get something unstuck, lifted, or loaded, an electric winch can save a ton of back-breaking work.

The hardest part may be deciding which one you need.

Winches are commonly available with either a 12V DC or a 110V AC motor.

For fixed operations, such as a marine railway, a 110V winch works well because it can be plugged into an electrical outlet.

For portable applications or use with a vehicle as the anchor, a 12v Winch is the way to go. These units can be hard-wired into a vehicle or simply hooked up to a battery.

The next consideration is capacity-what weight rating should you look for? As a general rule, take the maximum load that you expect to winch and multiply it by 1.5. The weight rating is based on the first wrap of the cable around the drum. With each layer of cable, the pull capacity actually drops, so when in doubt, go larger.

Always stay well to the side of a working winch, and always drape a heavy jacket or tarp over the line. If a cable breaks, the heavy material will help absorb the energy of the taut cable as it snaps back, and reduce the chance of injury.

If a load outweighs your winch rating, remember those high school physics lessons about pulleys and mechanical advantage. You can double the pulling capacity by [doubling" the line. Run it through a Snatch Block attached to the object you`re moving and then back to a fixed object. Twice the capacity, however, equals half the pulling speed.
