Mini Project Of ECE On Wireless Data Transmission Between Computers Using Sequence

Posted: 10 Sep 2010 05:15 AM PDT

ABSTRACT
Here for the purpose, we have made four distinct stages for the effective implementation .The stages are described in brief as follows. In the first stage, we are constructing the transmitter circuit that transmits data and sequence bits at infrared frequency. Now the second part is to develop receiver circuit that receives infrared signals coming out from transmitter and convert them into bits. The next stage is to compare the incoming sequence with that of receiver computer. If sequence is matched only then it will be able to catch the data sent by transmitting computer. The fourth and final stage is the make software program that gets the data and displays on computer.
INTRODUCTION
Wireless data transmission between computers is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN within a building. It can further be extended to wireless LAN with secure data transmission. For the purpose of secure data transmission a unique code is sent before actual data bits. This unique code is known to receiver. In this project sequence detector at receiver side has been used which is set for a particular code. This sequence detector detects binary bit stream coming out from transmitter and if code of incoming bit stream is matched with the code of sequence detector than rest of bits are received in form of data at the receiving computer's side. To further enhance the concept of security we are using Infrared waves as a channel between transmitter and receiver because security of infrared systems against eavesdropping is better than that of radio systems. The block diagram of whole system is shown below.

deleting multiple rows from database in php

Posted: 10 Sep 2010 03:19 AM PDT

this is the code that i have wrote for deleting multiple rows from database. but on pressing delete button instead of deleting a selected row it comes back to the same page again.. so i want someone to correct my code or give me the rite code for deletion. thank you



<?php
// Check if delete button active, start this
if($delete)
{
for($i=0;$i<$count;$i++)
{
$del_id = $checkbox[$i];
$sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
$result = mysql_query($sql);
}

// if successful redirect to delete_multiple.php
if($result)
{
echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">";
}
}
mysql_close();
?>

BAE MAS UK Layoffs: 700 employees to lose jobs

Posted: 10 Sep 2010 02:04 AM PDT

BAE's Military Air Solutions (MAS) will cut about 700 jobs over the next few days.
At the company's Farnborough facility, 55 jobs could be slashed because of the government's 2009 decision to reduce the number of Harriers in service, together with the imminent completion of the current contracted capability upgrades to the GR9 aircraft.

What exactly a "End task" feature do(Task Manager) which a "Close" Feature can't?

Why doesn't simply closing a non-responding document works?:confused:
