While the lock provides for the physical security of the Electronic Security System, the access control devices actuate the locking mechanism after validating the credentials of the owner and generating the signal for locking or unlocking the lock (Abloy, 2011). The monitoring system is to keep an eye of the lock tracking the movement of any object nearby, to maintain a database for the access control and to keep the recorded data available for ready access.
The mechanical locks form the heart of the security system and are available in a variety of designs. A pin tumbler lock is proposed to for the heart of the locking mechanism. In the pin tumbler lock, the key fits into a rotatable tube, called a plug, which sits within a fixed cylinder known as the shell (Phillips, 2005). Rotating the plug within the shell operates the locking mechanism. When the lock is locked, the plug is prevented from rotating by little sticks of metal under spring pressure that protrude from the plug into the shell. Each stick, known as a pin stack, is cut into two (or more) pieces (pins) at one or more of a standard, discrete set of positions. When the lock is empty, the cuts in the pin stacks sit inside the plug and the ends of the outermost pins protrude into the shell. When a correct key is inserted, it lifts each pin stack to a height where the cut is precisely aligned with the boundary between plug and shell. This enables the plug to turn and operate the mechanism.
The design of the electromechanical lock utilizes solenoid as main power in order to activate the lifting mechanism of the pin stack. Solenoid in general creates linear motion due to its force stroke characteristics. Energy efficient and forceful operation of the solenoid is vital for proper operation and longevity ...Download file to see next pagesRead More

Mechanical Heart
The heart has four chambers, four valves and blood vessels which are joined. These chambers and valves are the main elements of the heart system. The four chambers perform different functions. Normally, these valves allow blood flow in one direction. If there is a deviation from the normal blood flow through the heart, as in the instance of a congested heart failure, a viral attack on the heart, extremely high blood pressure, disrupting the heart’s rhythm, a heart attack, malfunctioning of the valve or other heart related issues, which is often the result of a diseased heart.
