Information on IR remote control
Citation preview
By: Adam Benson
Infrared Remote Control
Remote controls were first developed in the early 1900’s
Now remotes us IR (Infrared Remote) control They can control multiple different thing and
all at the same timeThey are not only used for entertainment but
also military, industry, and recreation(Arment,2006 whole text)
Intro
Infrared Remote Controls developed in the late 1970’s
Infrared Remote Controls use infrared light and photo receptors
Uses different light frequencies for different functions.
(Wikipedia, 2010, sec 5)
The Basics
These remotes use invisible light beams to send signals to electronic devices
Light is received by receptors in devicesDifferent frequencies do different thingsInfrared Remote controls today can control
many different devices at one time (Wikipedia, 2010, section 5)
How they work
Light is sent out by remote control and is received by phototransistor
If line of sight is not possible IR extenders help out
They receive signals and transmit signals to device via radio waves
(Wikipedia, 2010, sec. 9)
How signal is recieved
Nikola Tesla first to use remote control on toy boat
Philco Mystery Control (1939) was first wireless remote for electronic devices
First Infrared Remote controls developed in 1977-78
Produced by ITT (Arment, 2006, Sec 2)
Creator/Inventor
First remotes connected with wires to devicesFirst wireless remote used to control a toy
boatNext moved to visible light beams and sound
wavesThen Infrared Remote controls introducedNow radio waves are more common because
of problems with pointing light beam at receptor.
(Arment, 2006, Sec 2)
History
Changed to Infrared Remote Control for a couple of reasonsProblems with early remotesEarly remote controls could be ineffectiveOutside sources could also change
channels/volumePeople wanted to be able to control more
functions (Wikipedia, 2010, sec. 2)
History Continued
They can control a multiple of different of things including-TV’SRadiosDVD/CD playersVideo GamesToysMilitary UsesSpace/NASA (Wikipedia, 2010, sec .“usage”)
Uses
TV’s are the most popular use of infrared remote controls
Used for multiple functions on the TVAlso used for controlling electronics
connected to TV (History, 2010, par. 22-23)
TV Uses
Use same basic principles as TV remote controllers
Use same types of light beams to control functions of player
Now usually all combined into one type of remote
(Arment, 2006, last 5 par.)
Radio,DVD,CD Players
Used to control multiple electronic devices First invented in the late 1970’sNow the most common type of remote (History, 2010, par. 22-23)
Multi Use Controllers
Used in many different applicationsUsed in missile control and electric warfareUsed in IED detonation New IED’s are immune to radio detonation (Arment, 2006, sec 2 par 2-3) (Wikipedia, 2010, sec “military”)
Military Uses
Used to control Sub stationsPump Storage Power StationsHDVC plants (Wikipedia,2010, section “industry”)
Industry Uses
Infrared remote controls can be used with video games
Makes wireless play a lot easierAll major video game consoles now use
Infrared remote control or radio control (Goh, 2008, pg. 1)
Intertainment Uses
Infrared Remote Control has had a big impact on today’s world
Has freed us from wires and has made entertainment and industry faster and easier
