Liefde is rock solid. Perfeksie in die kleinste vorm. Heliograph — A heliograph is a wireless solar telegraph that signals by flashes of sunlight reflected by a mirror.

The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter, the heliograph was a simple but effective instrument for instantaneous optical communication over long distances during the late 19th and early 20th century.

Its main uses were military, survey and forest protection work, heliographs were standard issue in the British and Australian armies until the s, and were used by the Pakistani army as late as Most heliographs were variants of the British Army Mance Mark V version and it used a mirror with a small unsilvered spot in the centre.

The sender aligned the heliograph to the target by looking at the target in the mirror. Keeping his head still, he adjusted the aiming rod so its cross wires bisected the target.

This indicated that the sunbeam was pointing at the target, the flashes were produced by a keying mechanism that tilted the mirror up a few degrees at the push of a lever at the back of the instrument.

If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the rod was replaced by a second mirror, to capture the sunlight from the main mirror.

Signal Corps heliograph mirror did not tilt and this type produced flashes by a shutter mounted on a second tripod.

The heliograph had some great advantages, however, anyone in the beam with the correct knowledge could intercept signals without being detected.

In the Boer War, where both sides used heliographs, tubes were used to decrease the dispersion of the beam. The distance that signals could be seen depended on the clarity of the sky.

A clear line of sight was required, and since the Earths surface is curved, under ordinary conditions, a flash could be seen 30 miles with the naked eye, and much farther with a telescope.

The maximum range was considered to be 10 miles for each inch of mirror diameter, mirrors ranged from 1. The record distance was established by a detachment of U.

S, the German professor Carl Friedrich Gauss of the University of Göttingen developed and used a predecessor of the heliograph in His device directed a beam of sunlight to a distant station to be used as a marker for geodetic survey work.

Similarly, the story that a shield was used as a heliograph at the Battle of Marathon is a modern myth, what Herodotus did write was that someone was accused of having arranged to hold up a shield as a signal.

History of the Internet — The history of the Internet begins with the development of electronic computers in the s.

Initial concepts of packet networking originated in several science laboratories in the United States, United Kingdom. Today the Internet continues to grow, driven by ever greater amounts of information, commerce, entertainment.

Such communication systems were limited to point to point communication between two end devices. Telegraph systems and telex machines can be considered precursors of this kind of communication.

The Telegraph in the late 19th century was the first fully digital communication system, fundamental theoretical work in data transmission and information theory was developed by Claude Shannon, Harry Nyquist, and Ralph Hartley in the early 20th century.

Early computers had a processing unit and remote terminals. As the technology evolved, new systems were devised to allow communication over longer distances or with higher speed that were necessary for the computer model.

These technologies made it possible to exchange data between remote computers, however, the point-to-point communication model was limited, as it did not allow for direct communication between any two arbitrary systems, a physical link was necessary.

The technology was considered unsafe for strategic and military use because there were no alternative paths for the communication in case of an enemy attack.

With limited exceptions, the earliest computers were connected directly to terminals used by individual users, such networks became known as local-area networks.

Networking beyond this scope, known as wide-area networks, emerged during the s, J. History of mobile phones — The history of mobile phones, covers mobile communication devices which connect wirelessly to the public switched telephone network.

While the transmission of speech by radio has a history, the first models that were wireless, mobile. The first such devices were barely portable compared to todays compact hand-held devices, before the devices that are now referred as mobile phones existed, there were some precursors.

In a Professor Albert Jahnke and the Oakland Transcontinental Aerial Telephone and they were accused of fraud and the charge was then dropped, but they do not seem to have proceeded with production.

Beginning in the German railroad system tested wireless telephony on military trains between Berlin and Zossen, in , public trials started with telephone connection on trains between Berlin and Hamburg.

In , the company Zugtelephonie A. G, the portrayal of a Utopia of mobile phone in literature dates back to the year It is found in Erich Kästners childrens book The 35th of May, or Conrads Ride to the South Seas, hand-held radio transceivers have been available since the s.

Mobile telephones for automobiles became available from some companies in the s. Early devices were bulky, consumed high power, and the network supported only a few simultaneous conversations, modern cellular networks allow automatic and pervasive use of mobile phones for voice and data communications.

One of the earliest fictional descriptions of a phone was the science fiction novel Space Cadet by Robert Heinlein.

The protagonist, who has just traveled to Colorado from his home in Des Moines, receives a call from his father on a pocket telephone.

Before going to space he decides to ship the telephone home since it was limited by its range to the neighborhood of an earth-side relay office.

Ten years later, an essay by Arthur C. Clarke envisioned a personal transceiver, so small and he wrote, the time will come when we will be able to call a person anywhere on Earth merely by dialing a number.

Such a device would also, in Clarkes vision, include means for global positioning so that no one need ever again be lost, later, in Profiles of the Future, he predicted the advent of such a device taking place in the mids.

TV series Get Smart depicted spy gadgets with mobile telephones concealed in random objects, in the USSR, Leonid Kupriyanovich, an engineer from Moscow, in developed and presented a number of experimental models of handheld mobile phones.

The weight of one model, presented in , was only 70 g, however, in the USSR the decision at first to develop the system of the automobile Altai phone was made.

In , Bulgarian company Radioelektronika presented on the Inforga international exhibition in Moscow the mobile automatic phone combined with a base station, solutions of this phone were based on a system developed by Leonid Kupriyanovich.

One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, Pagers operate as part of a paging system which includes one or more fixed transmitters, as well as a number of pagers carried by mobile users.

These systems can range from a restaurant system with a single low-power transmitter, in the s, the widespread availability of cellphones and smartphones has greatly diminished the pager industry.

This resilience has led public safety agencies to adopt pagers over cellular, the first telephone pager system was patented in by Alfred J.

Bellboy was the first commercial system for personal paging and it also marked one of the first consumer applications of the transistor, for which three Bell Labs inventors received a Nobel Prize in Physics in Solid-state circuitry enabled the Bellboy pager, about the size of a small TV remote device, to fit into a pocket or purse.

The Bellboy was a terminal that notified the user when someone was trying to call them, when the person received an audible signal on the pager, he found a telephone and called the service centre, which informed him of the callers message.

The ReFLEX protocol was developed in the mid s, another is a facility handling classified information, where various radio transmitter or data storage devices are excluded to ensure security.

First responders in rural areas with inadequate cellular coverage are often issued pagers, volunteer firefighters, EMS paramedics, and rescue squad members usually carry pagers to alert them of emergency call outs for their department.

These pagers receive a tone from a fire department radio frequency. Restaurant pagers are in use in the s. Customers are given a portable receiver that usually vibrates, flashes, Pagers have been popular with birdwatchers in Britain and Ireland since , with companies Rare Bird Alert and Birdnet Information offering news of rare birds sent to pagers that they sell.

Telus, one of the three major carriers, announced the end to its Canadian pager service as of March 31, Many paging network operators now allow numeric and textual pages to be submitted to the paging networks via email and this can result in pager messages being delayed or lost.

Older forms of message submission using the Telelocator Alphanumeric Protocol involve modem connections directly to a paging network, for this reason, older forms of message submission retain their usefulness for disseminating highly-important alerts to users such as emergency services personnel.

Photophone — The photophone is a telecommunications device that allows transmission of speech on a beam of light. It was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19,, at Bells laboratory at L Street in Washington, both were later to become full associates in the Volta Laboratory Association, created and financed by Bell.

On June 3,, Bells assistant transmitted a voice telephone message from the roof of the Franklin School to the window of Bells laboratory.

Bell believed the photophone was his most important invention, the photophone was a precursor to the fiber-optic communication systems that achieved worldwide popular usage starting in the s.

The master patent for the photophone was issued in December , in its initial form, the photophone receiver was also non-electronic.

Bell found that many substances could be used as direct light-to-sound transducers, in its ultimate electronic form, the photophone receiver used a simple selenium cell at the focus of a parabolic mirror.

The cells electrical resistance varied inversely with the light falling upon it, i. Bell used the name for a while but it should not be confused with the later invention radiophone which used radio waves, in his experiments, Sabine used a meter to see the effects of light acting on selenium connected in a circuit to a battery.

However Bell reasoned that by adding a telephone receiver to the circuit he would be able to hear what Sabine could only see.

In an April 1, Washington, D. The telephone itself was something of a novelty, and radio was decades away from commercialization.

He wrote somewhat enthusiastically, Bell transferred the photophones intellectual property rights to the American Bell Telephone Company in May , factors such as the weather and the lack of light inhibited the use of Bells invention.

Not long after its invention laboratories within the Bell System continued to improve the photophone in the hope that it could supplement or replace expensive conventional telephone lines.
