History Of The Remote Control Apr 17, 2017

Who in the end invented the first remote control is not a test, but one of the earliest remote controllers is an inventor called Nikola Tesla (Nikola Tesla) (1856-1943), which he once worked for Edison, developed in 1898 (American patent No. 613809), called "Method of and Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles.

The earliest remote control used for television is the American Electric Appliance company called Zenith (the company is now acquired by LG), invented in the 1950, initially wired. 1955, the company developed a wireless remote control device known as the "Flashmatic", but the device was not able to distinguish whether the beam was coming from the remote control and required alignment. Robert Edler, Robert Adler, developed a remote control called the Zenith Space Command, 1956, this is also the first modern wireless remote control device, he is using ultrasound to tune the Channel and volume, each button to emit different frequencies, but this device may also be disturbed by the general ultrasound, and some people and animals (such as dogs) listen to the voice of the remote.

In the 1980 years, when the infrared semiconductor device was developed, the ultrasonic control device was replaced slowly. Even if other wireless transmission modes (such as Bluetooth) are continually developed, this technology is still widely used until now.
