Working
The working of HACS model (shown in Figure 1) is explained:-
PC: PC being the main module has HACS system installed on it. The two subsystems; one being
appliances control is responsible for ubiquitous access of appliances and the second subsystem
being security alert is responsible for security intrusion detection. Both subsystems work on GSM
technology for transmission of instructions from sender to receiver.
GSM Modem: GSM modem is a plug and play device and is attached to the PC which then communicates
with the PC via RS232 p ....etc

GSM MODEM

A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves. It can be an external device or a PC Card / PCMCIA Card. Typically ....etc

1.Abstract
Mechatronic systems for vehicles have received increased importance for improving automotive safety and comfort. These systems are designed to aid the driver by preventing unstable or unpredictable vehicle behavior and to stabilize the horizontal and vertical motion of the vehicle. This is achieved by the integration of actuators, sensors and data processing. However, the attained benefits are paralleled by an increase in the complexity of the system requiring enhanced methods for fault detection and diag ....etc

The 8051 Primer board is specifically designed to help students to master the required skills in the area of embedded systems. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The kit supports in system programming (ISP) which is done through serial port.

NXP s 8051 (89V51RD2), 8051 Primer Kit is proposed to smooth the progress of developing and debugging of various designs encompassing of High speed 8-bit Microcontrollers.
