History One of the earliest examples of remote control was developed in 1898 by Nikola Tesla, and described in his patent, U.S. Patent 613,809, named Method of an Apparatus …for Controlling Mechanism of Moving Vehicle or Vehicles . In 1898, he demonstrated a radio-controlled boat to the public during an electrical exhibition at Madison Square Garden. Tesla called his boat a "teleautomaton".  In 1903, Leonardo Torres Quevedo presented the Telekino at the Paris Academy of Science, accompanied by a brief, and making an experimental demonstration. In the same time he obtained a patent in France, Spain, Great Britain, and the United States. The Telekino consisted of a robot that executed commands transmitted by electromagnetic waves. It constituted the world's first apparatus for radio control [ citation needed ] and was a pioneer in the field of remote control. In 1906, in the presence of the king and before a great crowd, Torres successfully demonstrated the invention in the port of Bilbao, guiding a boat from the shore. Later, he would try to apply the Telekino to projectiles and torpedoes, but had to abandon the project for lack of financing. The first remote-controlled model aeroplane flew in 1932, and the use of remote control technology for military purposes was worked intensively during the Second World War, one result of this being the German Wasserfall missile. By the late 1930s, several radio manufacturers offered remote controls for some of their higher-end models.  Most of these were connected to the set being controlled by wires, but the Philco Mystery Control (1939) was a battery-operated low-frequency radio transmitter,  thus making it the first wireless remote control for a consumer electronics device. Radio Remote Control Systems .
Radio remote control (RF Remote Control) is a way to control distance objects using a variety of radio signals transmitted by the remote control device. By using radio remote control system, you can control a variety of mechanical or electronic devices to complete various operations, such as closing circuit, move handle, start motor, etc. As a complementary method to infrared remote control type, the radio remote control is widely used in garage door remote control, electric gate remote control, automatic barrier remote control, burglar alarm, industrial remote control and wireless home alarm systems. A radio remote control system commonly has two parts: transmit and receive. Transmitter part is generally divided into two types, namely, rf remote control and transmitter module, by the way of using, the rf remote control can be used independently as a whole while the transmitter module is used as a component in the circuit, the advantage of using transmitter model is it can be seamlessly connected with application circuit, and it's size is small, but users must have a knowledge of circuit to use the transmitter module, the rf remote control is much more easy to use at this point. Receiver part also is generally divided into two types, namely, the super-regenerative receiver and the superheterodyne receiver, super-regenerative receiver is actually working like the regeneration of under intermittent oscillation detection circuit. While Superheterodyne type is working like the one in radio receiver. Superheterodyne receiver features stability, high sensitivity and the anti-interference ability is relatively good, while super-regenerative receiver features a small package and the price is also cheaper. Fixed-code RF Remote Control DIP Switch Calculator Tri-state DIP switches are widely used in fixed-code RF Remote Controls to define the code of address pins, while in many circumstances, it's usually useful to calculate the dip switch settings, a calculator like the following will save you a lot of time. http://www.solidremote.com/tools/tri-state-dip-switch-calculator The RF Remote Control Tri-State DIP Switch Calculator is capable of calculating DIP switches up to 8 positions, and will convert any number from 0 to 38-1 to ternary and then display it in a visual form. Our RF Remote Control Tri-State DIP Switch Calculator will assist you working out ternary values in addressing various fixed-code RF Remote Controls, thus making the DIP switch settings for RF Remote Control addressing more efficiently.
