I have been granted patent #5,925,128 for
wireless computer control using the 3 prong
power plug. It can be used with an X10 unit.
The advantages of using this method vs.
password is to install you simply plug it
in ( a tiny key required to remove it so it
can't be bypassed )
Imagine the comfort a working parent has by
knowing your children are not online
unsupervised. You could even put a time
limit on the PC's daily use
