Introduction to Industrial Electronic Repairs

There are many aspects of the electronics business. They include the sales and installation of the electronic equipment, as well as its monitoring and evaluation. Industrial electronic repairs form that branch of business that handles the different facets of manufacturing. Industrial electronic repair forms an essential part of all maintenance schedules of the manufacturing companies. Else, the personnel trained for the repairs of electronic equipment get occupied when an electronic equipment stops working.

Generally, a thin line of demarcation is present between what is called industrial electronic repairs and domestic electronic repairs; this is because of the vast variety of industrial equipment. A number of industrial manufacturers and other kinds of businesses generally employ a number of electronic machines necessarily required to keep their businesses running efficiently. Some such machines and equipment for that purpose are printed circuit boards, tool controls and electronic control for temperature, timers and computers.

One very important aspect of industrial electronic repairs is to diagnose the fault in order to assess the status of the faulty electronic apparatus, and thus to identify the components necessarily needed to bring it back to working order. The precise way of repairing the electronic equipment varies with the company and its business strategy. One can find many online companies undertaking such repairs. Some of those companies may be outsourcing their services to qualified and competent repairers, working as independent contractors or working with professional companies. Industrial electronic repair could also imply replacing older or obsolete electronic equipment with new, more modern and more efficient models. In the present competitive world, such replacement often becomes necessary to get an edge over the competitors by enhancing the productivity to quickly produce more accurate and efficient equipment.

Some electronic equipment repairs may be carried at the premises of the client, while others may need to be carried back to the workshop of the entity undertaking the repairs, in order to diagnose the fault and eliminate it. It all depends on the kind of fault encountered. Companies undertaking repairs may offer various incentives to their clients. Common incentives include free diagnosis, discounts when buying fresh parts, free evaluation and extended warranties on the services provided. Some companies may offer to collect the faulty items from the customer’s premises without any charge, or at nominal expense. Companies offering services of industrial electronic repair could also provide online forms, allowing clients to describe the problem they may be facing, enabling the company’s representative to come better prepared for removing the fault.

Electronic World – How We Use Electronics in Daily Life

Using electronics today is so much a part of our daily lives we hardly think of the way the world would be without electronics. Everything from cooking to music uses electronics or electronic components in some way. Our family car has many electronic components, as does our cooking stove, laptop and cell phone. Children and teenagers carry mobile phones with them everywhere and use them to take and send pictures, videos, and to play music. They send text messages on the cell phone to other phones and to their home computers.

Wireless internet is becoming more common all the time, with laptops set up in cyber cafes where people can drink coffee and check their email all at the same time. The computer user can do all the web searching in relative privacy thanks to the electronic accessories which can be added to the computer. Conversely, more and more transactions are being sent electronically across the airwaves so security is becoming a larger issue than ever before. Merchants who sell products online must be able to assure their customers that information submitted at a website is not being accessed by unauthorized personnel.

Music is a prime user of electronics, both in recording and in playback mode. Stereos, record players, tape decks, cassette players, CD drives and DVD players are all the result of advances in electronics technology in the last few decades. Today people can carry a playlist of hundreds of songs around with them easily in a very small device–easily portable. When you add Bluetooth or headphones the music can be heard by the user, but does not disturb those nearby.

Electronics technology in cameras has increased dramatically. A digital camera is available to most Americans at a price they can afford and cellphones often includes a fairly sophisticated digital camera that can capture still pictures or even video pictures and store them or transfer them to a computer where they can be saved, shared digitally with family or friends or printed out in hard form with a photo printer device. Pictures obtained through a camera or by means of a scanner can be edited, cropped, enhanced or enlarged easily through the marvel of electronics.

Literally thousands of everyday devices that we use constantly make use of electronics technology in order to operate. These are products ranging from automotive engines to automated equipment in production settings. Even artistic efforts benefit from computer modeling prior to the committing of valuable artistic media to create the finished product.

Electronic Keyboards – Their History and Development

The term “electronic keyboard” refers to any instrument that produces sound by the pressing or striking of keys, and uses electricity, in some way, to facilitate the creation of that sound. The use of an electronic keyboard to produce music follows an inevitable evolutionary line from the very first musical keyboard instruments, the pipe organ, clavichord, and harpsichord. The pipe organ is the oldest of these, initially developed by the Romans in the 3rd century B.C., and called the hydraulis. The hydraulis produced sound by forcing air through reed pipes, and was powered by means of a manual water pump or a natural water source such as a waterfall.

From it’s first manifestation in ancient Rome until the 14th century, the organ remained the only keyboard instrument. It often did not feature a keyboard at all, instead utilizing large levers or buttons that were operated by using the whole hand.

The subsequent appearance of the clavichord and harpsichord in the 1300’s was accelerated by the standardization of the 12-tone keyboard of white natural keys and black sharp/flat keys found in all keyboard instruments of today. The popularity of the clavichord and harpsichord was eventually eclipsed by the development and widespread adoption of the piano in the 18th century. The piano was a revolutionary advancement in acoustic musical keyboards because a pianist could vary the volume (or dynamics) of the sound the instrument produced by varying the force with which each key was struck.

The emergence of electronic sound technology in the 18th century was the next essential step in the development of the modern electronic keyboard. The first electrified musical instrument was thought to be the Denis d’or (built by Vaclav Prokop Dovis), dating from about 1753. This was shortly followed by the “clavecin electrique” invented by Jean Baptiste Thillaie de Laborde around 1760. The former instrument consisted of over 700 strings temporarily electrified to enhance their sonic qualities. The later was a keyboard instrument featuring plectra, or picks, that were activated electrically.

While being electrified, neither the Denis d’or or the clavecin used electricity as a sound source. In 1876, Elisha Gray invented such an instrument called the “musical telegraph.,” which was, essentially, the very first analog electronic synthesizer. Gray discovered that he could control sound from a self-vibrating electromagnetic circuit, and so invented a basic single note oscillator. His musical telegraph created sounds from the electromagnetic oscillation of steel reeds and transmitted them over a telephone line. Grey went on to incorporate a simple loudspeaker into his later models which consisted of a diaphragm vibrating in a magnetic field, making the tone oscillator audible.

Lee De Forrest, the self-styled “Father Of Radio,” was the next major contributor to the development of the electronic keyboard. In 1906 he invented the triode electronic valve or “audion valve.” The audion valve was the first thermionic valve or “vacuum tube,” and De Forrest built the first vacuum tube instrument, the “Audion Piano,” in 1915. The vacuum tube became an essential component of electronic instruments for the next 50 years until the emergence and widespread adoption of transistor technology.

The decade of the 1920’s brought a wealth of new electronic instruments onto the scene including the Theremin, the Ondes Martenot, and the Trautonium.

The next major breakthrough in the history of electronic keyboards came in 1935 with the introduction of the Hammond Organ. The Hammond was the first electronic instrument capable of producing polyphonic sounds, and remained so until the invention of the Chamberlin Music Maker, and the Mellotron in the late 1940’s and early 1950’s. The Chamberlin and the Mellotron were the first ever sample-playback keyboards intended for making music.

The electronic piano made it’s first appearance in the 1940’s with the “Pre-Piano” by Rhodes (later Fender Rhodes). This was a three and a half octave instrument made from 1946 until 1948 that came equipped with self-amplification. In 1955 the Wurlitzer Company debuted their first electric piano, “The 100.”

The rise of music synthesizers in the 1960’s gave a powerful push to the evolution of the electronic musical keyboards we have today. The first synthesizers were extremely large, unwieldy machines used only in recording studios. The technological advancements and proliferation of miniaturized solid state components soon allowed the production of synthesizers that were self-contained, portable instruments capable of being used in live performances.

This began in 1964 when Bob Moog produced his “Moog Synthesizer.” Lacking a keyboard, the Moog Synthesizer was not truly an electronic keyboard. Then, in 1970, Moog debuted his “Minimoog,” a non-modular synthesizer with a built-in keyboard, and this instrument further standardized the design of electronic musical keyboards.
