Telephone
A telephone, colloquially referred to as a phone, is a telecommunications device that enables two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via Electrical cable, cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from and (, ''voice''), together meaning ''distant voice''. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a microphone (''transmitter'') to speak into and an earphone (''receiver'') which reproduces the voice a ...

Gray is best known for his Invention of the telephone, development of a telephone prototype in 1876 in Highland Park, Illinois. Some recent authors have argued that Gray should be considered the true inventor of the telephone because Alexander Graham Bell allegedly stole the idea of the liquid transmitter from him. Although Gray had been using Elisha Gray and Alexander Bell telephone controversy#Use of liquid transmitters for telephone experiments.2C 1873-1876, liquid transmitters in his telephone experiments for more than two years previously, Bell's Invention of the telephone, telephone patent was upheld in numerous court decisions.

Patent Application
A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claim (patent), claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office. To obtain the grant of a patent, a person, either legal or natural, must file an application at a patent office with the jurisdiction to grant a patent in the geographic area over which coverage is required. This is often a national patent office, but may be a regional body, such as the European Patent Office. Once the patent specification complies with the laws of the office concerned, a patent may be granted for the invention described and claimed by the specification. The process of "negotiating" or "arguing" with a patent office for the grant of a patent, and interaction with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent Caveat
A patent caveat, often shortened to caveat, was a legal document filed with the United States Patent and Trademark Office, United States Patent Office. History Caveats were instituted by the US Patent Act of 1836, U.S. Patent Act of 1836, but were discontinued in 1909, with the United States Congress, U.S. Congress abolishing the system formally in 1910. A caveat was similar to a patent application with a description of an invention and patent drawing, drawings, but without examination for patentable subject matter and without a requirement for claim (patent), patent claims. A patent caveat was an official notice of intention to file a patent application at a later date. A caveat expired after one year, but could be renewed by paying an annual renewal fee, annual fee of $10. Caveats were similar to provisional applications used today in the United States Patent and Trademark Office (USPTO) which also expire after one year. However, provisional applications today are non-renewab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automaton
An automaton (; : automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions. Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power or will, like a mechanical robot. The term has long been commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters or creatures in films and in theme park attractions. Etymology The word ' is the latinization of the Ancient Greek (), which means "acting of one's own will". It was first used by Homer to describe an automatic door opening, or automatic movement of wheeled tripods. It is more often used to describe non-electronic moving machines, e ...

Reis Telephone
The Reis telephon was an early sound transmitting device, invented by Philipp Reis in 1857. Reis's first successful work is dated to October 1861. When properly set up, it would allow verbal communication via electronic signals. Many sources credit Reis as the inventor of the first telephone. Others point to the prior work of Antonio Meucci, or to later work of Elisha Gray or Alexander Graham Bell. However it is generally agreed that Reis coined the word ''telephon'' -- which has been Anglicised to telephone. History In 1861, Philipp Reis succeeded in creating a device that captured sound, converted it to electrical impulses that were transmitted via electrical wires to another device, which transformed these pulses into recognizable sounds similar to the original acoustical source. Reis coined the term ''telephon'' to describe his device. In 1862, Wilhelm von Legat, Inspector of the Royal Prussian Telegraph Corps, published an article on Reis' invention. von Legat provided ...
