LITTLE INVENTION
Can you imagine waching TV without the remote control?That means you need to get up from your comfortable sofa,walk all the way to the television and press the tuner every thime when you want to change the channel just by a click of a finger on the remote control.
The first TV remote control was called the Lazy Bones.It waas developed in1950 by a radio company.The Lazy Bones was different form what we have at home today.It had a tail of cable that linked to the TV set.There were complaints that people tripped over by the cable that wandered across the living room.Six years after,an Australian engineer,Dr Robert Adler,led a team of engineers to work on the first practical wireless TV remote control called the Space Command.Dr Adler used''ultrasonic''in the remote control to replace the cable to carry information.With this new technology,people could finally change the TV channel from anywhere in the living-room without getting up or tripping themselves.
