1.5 DEFINITIONS OF IMPORTANT TERMS
Transistor switch:
A
transistor is a semiconductor device used to amplify and switch
electronic signals and power. It is composed of a semiconductor material
with at least three terminals for connection to an external circuit. A
voltage or current applied to one pair of the transistor's terminals
changes the current flowing through another pair of terminals. Because
the controlled (output) power can be much more than the controlling
(input) power, a transistor can amplify a signal. Today, some
transistors are packaged individually, but many more are found embedded
in integrated circuits.
The transistor is the fundamental building
block of modern electronic devices, and is ubiquitous in modern
electronic systems. Following its release in the early 1950s the
transistor revolutionized the field of electronics, and paved the way
for smaller and cheaper radios, calculators, and computers, among other
things.
De-mobilizing: Which is also called immobilize. Simply means
an object not able to move or when something is motionless. So on the
case of a car, a car is said to be de-mobilized or immobilized when that
car is static or in a fix and is incapable to be moved.
The logic
unit: This comprise of the logic control nand logic flip flop circuit
which saves the 1 and zero signal that is being received from the mobile
phone. This unit is the main memory unit of the design that controls
when the signal to stop the car is received and when the signal to reset
movement is done.
Capacitor: Is an electronics device, used for storing charges.

ABSRACT - [ Total Page(s): 1 ]Car security systems are still of no match to the well-equipped thieves. It is just a matter of seconds to break through the system. This project introduces and describes the design of mobile controlled car security system offering higher level of car security features. The mobile controlled car security is capable of providing an effective two-way communications between the alarm system and the car owner. This system is able to notify the car owner immediately when intrusion is detected. Additi ... Continue reading---
