A password lock, also known as a combination lock, is a security device that requires a specific sequence of numbers or symbols to unlock. Unlike traditional key-based locks, these locks rely on a code entered through a dial or digital keypad. The term "password" in this context is often used loosely, as the codes are typically just sequences rather than true combinations in the mathematical sense.
Most mechanical password locks consist of one or more rotating dials, each marked with numbers. As the user turns the dials to the correct sequence, internal mechanisms engage to release the locking mechanism. Some models use a single dial that controls multiple discs or cams inside the lock, while others have several separate dials that must be aligned in the right order.
These types of locks are commonly found in schools, gyms, and storage facilities due to their reliability and ease of use. They are also popular for securing luggage, lockers, and even some electronic devices. While they offer a level of security, it's important to note that password locks can sometimes be vulnerable to picking or brute-force attacks if the code is simple or easily guessed.
To maximize security, users should choose unique and complex codes, avoid using common sequences like "1234" or "0000," and keep their passwords private. Regular maintenance and proper installation are also essential to ensure the lock functions correctly over time. Whether you're using a classic dial lock or a modern digital version, understanding how password locks work can help you make the most of their convenience and protection.Corner cube Prism is also named retroreflector or trihedral prism.In the corner cube prism,three reflecting surfaces are perpendicular to each other,like the side wall of the cube.The input surface is perpendicular to the cube diagonal. Disregarding the anlge of the incidence,the output beam is parallel to the input one,but it is of opposite direction. Inset of the several corner prisms, for better matching,their extrance exit surface is often hexagonal.In case of this prism the phenomenon of full internal reflection occurs so it is not necessary,(however it is possible)to put mirror coating on the reflecting faces. Normally the reflection surfaces are AL reflection coating, and then covered with Cu and Black painting.Â
Pyramid prism/Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.
