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
