chapter 1 Introduction 9 System Description

The processing subsystem consists of main four parts:
 Zigbee
 Adapter
 Serial connection
 Laptop or computer
Zigbee : is that receives the transmitted signals wireless from the
other Zigbee in the hand subsystem.
USB-XBEE Adapter : Used to Connect Zigbee or Bluetooth Bee to
PC.
Serial connection: it is the serial cable that connects the Xbee
adapter with computer that receives the data serially.
Laptop or computer: it is the main part in this subsystem that
processes the received data based on specific program.
In The processing subsystem the stream of data that is received
from the hand subsystem through Zigbee . The analog outputs from
the Zigbee are then fed to Xbee adapter. It processes the signals
and perform analog to digital signal conversion. The resulting digital
signal is sent to Laptop or computer through the serial connection,
then Laptop or computer processes the received data based on
specific program.
