Colloidal Silver For Cataracts

. The Eagles return


British Sea Power.

This British band consists of five musicians, two of them brothers, have been among others, opening for bands like Interpol, the strokes, flaming lips, etc ... Straddling the Glam and Punk, interesting proposal where there. Pronounced psychedelic guitars and drums.
In late 2001 they released their first single, Rough Trade and initiate, and in 2002 a tour opening for Pulp. But seriously be baptized in 2003 when his first album The Decline Of British Sea Power The receiving very good reviews in Britain. Are

about to release their third album and already have your audience Ansis. Atom
I leave, one of its more than safe hits.

Facto Delafé and Las Flores Azules.
Barcelones
Although this group has one of the longest names of English music scene, this is a trio of excomponentes of other groups. Composed by Marc Barrachina
(Facto), Oscar D'Aniello (Delafé) and Helena Miquel (Las Flores Azules), betting on a pop serene, soothing, with hints of trip-hop with real soothing effect. Positive lyrical, very neighborhood where the typical verbiage of the purest hip-hop comes to absorb in a friendly atmosphere. Velvety voice of Helena.
count among their songs to the soundtrack to Bigas Luna's film "La Juani". Catalan provinientes

These groups like "Songstore", "Elena" and "Mishima," among other accolades best demo of 2004 in the program Disco Grande de Radio3.

In order that from this September we have a second job in the market "La Luz De La Mañana" and I believe will come some more. For those times round .... or not.

Musa? Good Charlotte


Sorry, where are you?

Without wishing to excuse, lately I find inspiration anywhere. It is as if the muse that in time would have gone with me, no goodbye, no explanation, no whys, no more.
Anyway, too early to surrender. In short, I promise, I will return to make war. Now is all I can say ....... and YES, Stefania, I'll update this your blog!

How To Visit Inmkates At Riker

K-OS


towards globalization of music.

Hello friends. It is difficult, in many cases to judge the quality of sound. Also it is to find something that really sounds like a new, original, fresh. When everything seems already invented, and someone will surprise us. The spice of life. And always bet on mergers and mixing sound as a weapon to overcome new musical boundaries. No you could say that I do not support the new formulas of sound, but I think where the quality is present, any style of music is worthy of mention.

Because this film? You see, some time ago that musicians are listening, that within the same work are introducing details funk, pop, rock, rap, reggae, etc. with great success ...., group. Case of K-Os, the group in question.


Canadian born in Toronto. His career began in 1993, but not until 2002 with his album "Exit", when it's popularity. Their music is a patchwork of sounds ranging from rap, funk, rock, reggae, etc ... It is usually a passionate critique of the world of hip-hop and its culture of money, power and violence. Later in 2004 come to light "Joyful Rebellion" would get the go platinum in Canada. Since late 2006, he published "Atlantis: Hymns for Disco" which has just given the final push.

How to show a button, I invite you to listen to a example of the quality and variety of its rhythms.

What Do All The Sag Bands Mean

TTL IC. ALARM TIMER

The technology used in TTL circuits is the basically use transistors and some other elements and devices. A transistor is a semiconductor electronic device (semiconductor is a substance that behaves like a conductor or an insulator depending on the electric field that is the most commonly used semiconductor is silicon) that acts as amplifier, oscillator, switch or rectifier.

following circuit is the construction of a TTL inverter

The basic function of an inverter is as its name suggests, invests the state that reach the entrance, for example: if-inlet comes a logical 1 output is going to give us a logical 0 and vice versa.


The circuit description is as follows:

The transistor marked on the diagram as Q1 is in charge attaching the input function diode D1 is to set the input level, the transistor Q2 is a phase splitter, Q3 and Q4 form combining the output circuit.

The name that is used commercially for the investor is NOT Gate and electric represtación is:




the standard TTL family more used to a NOT gate is 74LS04

In the previous figure we can see that there is a table that is called truth table, a table really helps us better understand the behavior element, the truth tables are made up of several columns and rows, the number of columns you have is going to depend on the number input and output, and the number of rows depends on the number of possible combinations that can generate at the entrance.

Several logic circuits, each characterized as an equation, truth table, then show you the most common logic circuits are used.

AND Gate (Standard TTL: 74LS08)

An AND gate has two inputs and minimum logic is a product operation between the two, is not a simple product, but in this case coincide.




OR gate (standard TTL: 74LS32)

The OR gate is also at least two falls das and logical operation is the sum between the two, only when 1 + 1 = 1.



For a better understanding of this gate, we use an array of switches and B as many and stra in figure below.



Buffer (standard TTL: 74LS17)


The buffer does not actually perform any logical operation, its purpose is to amplify the signal a bit. As you can see in the chart below the output signal is the same input.




Applications:

  • The TTL technology is currently used in the construction of:
  • Microprocessors
  • RAM Memory
  • PROM
  • PAL (Programmable Array Logic , consisting of a PROM inputs and interconnects number of logic gates).

PREAMBLE:

Today
l a real concern own is a constant, besides being also a constant current the fact of rising crime. Therefore, the person who is able to incorporate into your home alarm system, you get, no doubt, an advantage over those who can not. It seems that the possibility is remote because the high costs and limited availability for the preparation and installation more complicated purchase. However, in this documentary that I have prepared them to tell you the easiest way for you to arm their own alarm with high efficiency.

DEVELOPMENT

The project presented in this paper is an alarm wire sensors, very economical.

is powered by a 9V battery and this circuit triggers a siren when a sensor stops. The alarm remains on duty at a certain time, after which current consumption is reduced to zero, so that energy expenditure is reduced at rest. This is very important in the case of 9-volt battery, which will make more lasting utility.

The characteristics of this device are:

  • Power: 9V (battery)
  • Power consumption in standby mode: 10μA
  • Current consumption (max.): 150 mA. Load Impedance: 4 or 8 ohm
The

features just mentioned suggest that the consumption of inexpensive energy.

As shown in the block diagram of FIG. 1, the circuit is simple and uses few components.


FIG. 1 .- Block diagram of the alarm


The first section consists of sensors that are indeed thin wires that connect the points and objects that are to be protected, so connections that are disrupted by the slightest movement.

In standby, the sensors maintain continuity between the resistor R1 and the negative pole of the battery, having no bias for transistor Q1, which makes the oscillator remains off.

When stopping the sensor wire, the capacitor C1 starts charging through R1 and R2, then placing the oscillator in operation.

As the capacitor is loaded, the base current of Q1 and the voltage on the oscillator will decrease gradually until the oscillator and is not able to function. That is on hold.

The charging time depends on the time constant (Rl + R2) / C1, plus the input resistance by Q1, the resistance between the bases of Q2, etc.

With the component values \u200b\u200bshown, the alarm may sound for 3 minutes. As if we change the capacitor C1 by one of l000 uF, the time of operation will be from 4:30 minutes.

The third block represents the circuit diagram of oscillation.

As discussed already, it is a relaxation oscillator with unilateral transistor operating in the audio frequency. Using the values \u200b\u200bprovided in the bill of materials, work in the oscillator frequency of 4.5 KHz or so. Interested readers can experience the value of C2 alternating to change the sound.

LIST OF MATERIALS

Q1 = BD135

Q2 = 2N2646 - TRANSISTOR UNIJUNTURA

Q3 = BC548

EQUIVALENT

Q4 = TIP 31

Q5 = 2N3055 - NPN SILICON HIGH POWER

C1 = 470 uF 16 V - ELECROLITICO

C2 = 47 nF - CERAMIC

R1 = 82 K (gray, red, orange)

R2 = 22 K (red, red, orange)

R3 = 100 ohms (brown, black, brown)

R4 = 4.7 K (yellow, purple, red)

R5 = 1 K (brown, black, red)

R6 = 2.2 M (red, red, green)

Several

:

- Battery 9 V

- battery connector

- PCB

- loudspeaker 8 ohm

- Momentary contact key (S1)

- common switch (S2)

- sink to Q5

- wire

- welding


Note that C2 should be between 22NF (ceramic capacitor) and 4.7 F (electrolytic capacitor), as well as the frequency generated is in the audio band (20 Hz to 20 kHz). In the oscillator output have an amplifier stage formed by coupling three transistors in Darlington. This coupling generates an output gain much more that will be amplified audio signal too.

excite This circuit allows a speaker with good power 4 or 8 ohms, being efficient for the purposes of the project.

The complete circuit of the alarm shown in FIG. 2.





FIG. 2 .- Diagram of the circuit to build

Be the bridge mount terminals, and breadboard but the ideal is to make printed circuit board and that the alarm should occupy as little space as possible so that it is camouflaged. Ideally, this is not a view which contre lower risks to be disconnected.

In FIG. 3 gives the design of printed circuit board and component layout.


The power transistor (Q5) to be mounted outside of the plate and have a heat radiator, which can dissipate the heat distribution in the circuit, the current flow. For more volume, use a good quality speakerphone and 10 cm least.

We can be seen that only two sensors placed in the diagram (X, X2), but nothing prevents many units are connected in series. To mount the sensors use thin wires or strips of aluminum foil and then there will be greater sensitivity. These wires are attached to two points, one in the fixed and the other on the moving part of the window, for example, and connected the circuit, the main common thread through connection.



FIG. 3 .- Design plate



To test the alarm, the threads of the two sensors, press S1 and S2 operate.

disconnecting one wire sensors, with its disruption should trip the alarm immediately sound broadcasts. After some time the sound intensity gradually decreases until it stops.

Once activated, to reset the alarm should be reworked dropped connections and press S1. Checking the operation, could be the final installation.

FOR MY FRIENDS I HOPE THIS IDEA OF ALARM LES is to your liking. COMPONENTS ARE VERY EASY TO FIND.

ALSO IS A VERY IDEA ILLUSTRATED AS IT IS VERY EASY TO ASSEMBLE, YOU SHOULD HAVE NO PRIOR KNOWLEDGE OF ELECTRONICS.

THE VIRTUAL INSTRUMENTATION OSILOSCOPIO

To delve the subject of an oscilloscope is necessary to know some meanings or concepts of which will help us better understand the issue and make it easier to learn this.
Basics:

measurement: the comparison is of two things, it's as if we compare what is already known to something which we know as measured.
measurement instrument: is an object that allows us to make a measurement such as a rule.
Science: is responsible for studying the behavior of the issues that is referring them and the reactions around you to know how to merge and why.
Strength: is the physical ability to perform work.
matter: is anything that can be touched and that is composed of particles.
Particle is a small part of matter.
Electrical Load: is property of the particles to attract or repel. Electron
: are particles that contain an electrical charge.
Physical Phenomenon: is the behavior of an object.
Electrical is a physical phenomenon caused by electric charges. Appliance
: object which needs electricity to function.
Electronics: is the science that is responsible for studying the behaviors whose operation is based on electron movement and action of electrical forces.
Electrical: is an object which works through electricity.
Signal: is a symbol that represents something or warn of something in terms of electronics is to represent the behavior of a sound or an electric element.
Voltage: is the force that governs energy particles to be displaced.
Current: is the amount of energy passing through a place.
Displacement: is the change from place to place.
circuit or electrical circuit: is a set of electrical components.
Plano: place where you can represent a graph.
X axis or Y-axis: are the horizontal side (X axis) and vertical side (y axis) of a plane.
graphic representation or chart: is the way to show the figure of something on a plane.
Data: Information is or rather what is being communicated.
Memory: where data is stored.
Period: is the time it takes a signal to repeat his behavior.
Direct Current CD: are the signals that have only positive voltages. AC
CA: are the signals that are positive voltages and negative voltages.
Frequency: is the number of repetitions that has a signal.


Oscilloscope:



The oscilloscope is a measuring instrument that allows us to graphically represent the signal, figures are shown by a screen, which indicates the time of that signal through the x-axis and through the axis and indicates the voltage.


This screen is made up of a by divisions which are made by the axes above, these divisions can be controlled by knobs as we indicated equivalent each box, either the times or voltages above the axes.

oscilloscopes can change various things from the signal to which you are making measurements, you can work with direct current signals DC or AC power signals, also modify the working time signal.

oscilloscopes help us diagnose any problems with an electrical circuit (radio, tv or just an appliance containing such circuits), thanks to this device we can see different signals (different forms).

Some things we can do with an oscilloscope are:

* measure the period and the signal voltage

* can see part of the signal is CD and AC.

* We used to identify faults in a circuit.

Two types of oscilloscopes classified according to the internal operation performed by the oscilloscope:

Analog Oscilloscopes




The measured voltage will be sent to the vertical plates (vertical baffles) a mechanism to be viewed on the screen (CRT), the input signal introduce an amplifier which helps keep the signal more strongly by increasing some of its features while horizontal plates (horizontal deflection plates) of the mechanic, it will introduce a voltage signal called sawtooth (signal grows and falls repeatedly triangular or a saw pun intended), another terminal device positive and negative connected to another electronic device (which is plugged in moderating the electricity needed), to create a beam (light beam) passing through the plates that show us the signal is entering.




The analog oscilloscope has some limitations with which it works:
  • The signs must be repeated in a given time for these signals are known as periodic signals.
  • very fast signals reduce the brightness for display.
  • slow signals are not pictures to be shown, is so slow that the light beam is not no figure appears, and this does not help us make our measurements.

For this scope is used commonly used cables that are connected to the oscilloscope estradas call tip tips oscilloscope or direct. These cables are connected to the electrical circuit, the black terminal is for the negative polarity of the electrical circuits, also called earth ground (earth ground by definition is the lack of energy at a certain point, which helps energy flow through the circuit according to certain laws of electricity), and the red terminal is to the point where energy starts to the displacement of particles of the same.


Digital Oscilloscopes
















digital oscilloscopes contain a converter analog-digital which allows you to pass data to measure signals into digital form through processes which are called modulation (which consists in dividing the signals into small parts to a certain number of moments of time so that they could convert to digital processes which are represented by zeros and ones which, in turn symbolize signal voltages to be stored in internal memory of each oscilloscope and be shown to the user so that it can understand) in order to be measured in a more accurate, also helps us to measure many more things that that the analog could not perform, as different moments in which the beam of the display is triggered, the signal peaks as well functions that have analog oscilloscope.

This oscilloscope provides many measurements that would be done manually, can also use the leads (offset point) which we used to measure signals in electronic circuits, and these cables also allow us remove some unwanted signals that may occur, these unwanted signals are caused by the environment in which we work, because there is electricity in the air (static) affecting our measurements or because where they have no control over .



digital oscilloscopes have gradually been replacing analog scopes for their great reliability and accuracy in their measurements.

1. SUMMARY

This paper presents some of the most important e-mail addresses, in which they find all kinds of information relating to the electronics area, covering the following topics:

  • tutorials, manuals
  • Project
  • practices
  • Notes
  • Software
  • electronic devices
  • Forums
  • Goods Stores

2. INTRODUCTION

Since its inception, the man has had the need to communicate, so I'm looking for different forms of communication, which with the passage of time has been improved. Similarly always tried to be informed, and that this has allowed it to adapt to the lifestyle surrounding it.

Today we know that the forms of communication and the media have increased in a dreadful manner, in principle we know that everything that is invented or created is done to facilitate our work or avoid fatigue took so long performing some activity, but perhaps we realize that this makes us more and more useless, they had thought, good thinking not believe. However, we must accept everything that technology has allowed us to live in a better way, but if we pause a moment and reflect, the technology works on the basis of one of the areas of science that has evolved over the recent years, "The Electronic ."

Today at the Electronic is found everywhere in our house, transportation, work, school, etc. I would say it is impossible to set it aside, so it is important to be informed and even more, know how we can find information about a specific topic. Earlier books or magazines were the most viable option, but today the Internet has become their biggest rival.

My colleagues and I took on the task of finding web pages that present the best information, that in order for anyone to solve your problem in a given case or to clarify your question. The information presented in this simple investigation covers 7 main issues directly related to electronics, which are:

  • Software Projects Manuals
  • Forums
  • Notes
  • electronic devices
  • Shops Electronics

Although we know that the network is too much information, we have the experience we have gained in this area, we try to find the email addresses of pages that will help you out of trouble in they can find from basic information to large projects, just as you will find information on all the elements used in electronics, the main software used for circuit simulation, the major electronics stores, manual instrumentation, notes and of course he could not miss the main sites where you can give an opinion or criticize,

Finally I have nothing else to invite you to discover this beautiful and expansive world of electronics, hoping that the information that we recommend will be useful.

3. DEVELOPMENT

a) Projects, TUTORIALS AND MANUALS IN THE RED

In these days when information on the web we disoriented and we lost in this sea of \u200b\u200bpages of advertising and consumerism is important that we have a clear (albeit minimal) where we can find good information to our best advantage as students, workers or simply as fans of this great world of electronics.

In this section we know that we offer the network on Courses, Tutorials, and assembly of electronics, which has given a whole new era in the evolution of how we live and this can only in the last century of our era.

In the tutorials we will find a lot of information issue we need to get. The advantage of these types of information search on the net is that you have access to a lot of them and not just a few as in a library, you can get a lot of them for free, most of them have a purpose too practical and not only as educational or informational books. The tutorials usually consist of a series of steps that increase the level of difficulty and understanding. A tutorial is an instructional lesson that leads the user through the features and functions most important things as applications of electronics in our case. That is why we must remember where to get them without losing a lot of time on it.

If what you are looking for information, articles, definitions, dictionaries, electronic circuit assembly, tutorials, forums to find help in your work or school etc., Each of the pages shown Here are your thing, but to have a better idea and check which only some of the qualities we give some examples.

pages that have good information start encyclopedia type sections or topics are: http://www.ifent.org http://www.electronica2000.com

http://www.electronica2000.com/ has a basic electronics course with 83 chapters with simple definitions and biographies of important electronic, and special notes of how to weld, mini digital electronics course and electronic dictionary

www.unicrom.com Good amount of tutorials basics of digital circuits, sequential circuits, basic components such as gates and most advanced analog converters, multiplexers and decoders, TTL technology and more. In point of circuits is a great variety of these, for example the typical power supplies, signal amplifiers and programmer and memories PICS

http://www.ifent.org / default.htm page is a simpler but with some articles with good information from digital electronic passive filters, power supplies, relays etc stepper motors. And some tutorials how to notes (they are in English) with good information


http://www.webelectronica.com.ar/ With its list of assemblies or projects with http://www.yoreparo.com/ diagrams with his club, (and both have great information including articles, tutorials and forums) are certainly a great reference to see how practice all the skills of other Internet addresses that do not have these items in addition to being very good references for school projects and for industrial purposes.

http://www.solomanuales.org/manuales_electronica_digital

http://www.mundotutoriales.com/tutoriales_electronica_digital As its name suggests have a lot of manuals and tutorials various topics such as the Internet, communications, languages, humanities, to name a few. In regards to manual features 53 tracks of electronic manuals as: Introduction to electronics, electronic symbols, digital modulation, Application of electronics, most are free. In the tutorial only has 20 publications on topics such as What is a digital certificate?, Introduction to digital electronics, etc.

already mentioned in these pages are just a sample of what you could find on the net, the review you will notice that the item in electronics is very rough, with great use in practice and a lots of fans around the world.

b) SOFTWARE AND NOTES

With over 200 million users worldwide , Internet has become the means of communication more extended throughout the history of mankind . This aptly named "Red of networks, allows for cooperation and collaboration between many communities and groups of interest specific subjects, distributed across the planet. Through it you can find all kinds of software for a wide variety of computers and operating systems , please consult the catalogs of libraries in the world, access to databases with the most diverse and transfer copies of documents found, you can view and copy files of photo images of any kind or reproductions of paintings, can be things like talking to real time two or more people, separated by thousands of miles away.

The education has not escaped the influence of the Internet. Not only have created new methods of teaching (such as distance education real time) but have changed research methods and data collection . Currently, most students and teachers of secondary and higher seek information on the Internet before going to a library or bookstore. Among the many advantages of using the Net for this purpose are: the speed with which information can be found, the vast amount of data you can get about the same topic of interest; low cost that means not having to purchase a specific book , etc.

However, many teachers and other education professionals believe that this new method of collecting data is detrimental to learning for students, because it makes them very easy to copy papers whole, where all is done and only have to make few changes. And so, on this premise, the student is limited to "cut and paste chunks of text without having assimilated any knowledge .

This research aims to demonstrate that far from hurting the student, using the Internet as a source of information effectively enrich their knowledge and further motivates your creativity .

Applying this research to the Engineering degree in communications and electronics intends to make good use of network knowledge to students with this profile, after a collection of several pages, with notes and software for use and electronic learning found these pages that are considered the most complete our and contain much in common with the field of materials in the career of ICE, unfortunately there is always the possibility of unreliable content on the network, since many pages are not certified or subjected to a thorough review of a pro trained.

C) SHOPS Consumer Electronics

On the Internet, global network, there are different types of electronics stores. For example, there are electronic portals that companies with physical locations. On the other hand there are those who are "shopping" in situ , ie they offer their products via the Web and only by this means you can buy the items you need.

When an engineering student decides to undertake the search for these stores by the network encounters a big problem. What? Well, the major search engines (Yahoo, Google, MSN, etc.) Appear to be designed to deliver the results we want. Or just the demand for this type of stores is not as big as what the common people called "electronics." Yes, puts an "electronics" and appear refrigerators, televisions and even ipods; therefore need to be more specific.

Well, as we tackle these issues squarely to the question that concerns us. For communications and electronics engineering and other related careers can find some sites that are helpful when it comes to electronics. The first we must mention is one that bears the famous name Steren . And not be amiss to stress that is in all probability, the most famous shop in electronic commerce and traditional commerce. Just enough to tell one of the many students of electronics, "Steren" so that we respond with their typical "electronic solutions" (!!). But hey, let them tell us Steren managers what your store offers. Here we copied an excerpt from his presentation: "Steren Electronics is an established company thanks to a solid structure, the result of effort and dedication of those who lead and those who work for her. "Well, after this choro (which no doubt is true) copy its mission:

  • be leaders in the electronics market through excellent service, superb quality, wide selection, at a fair price.
  • Achieving the loyalty of our customers, employees and partners, based on respect, honesty, commitment and trust.
  • Foster teamwork and communication, fostering the development and improvement of all people within the organization.
  • Always maintain a culture of innovation, continuous improvement and growth , anticipating and adapting to changes in our environment.

The analysis we did of this page and its contents gives a satisfactory answer. That is, is very complete and among its virtues is that you can buy a variety of quality products both online and physical stores. Contrary is prevalent among some colleagues the idea that everything is Steren expensive than other stores, which is not always true. Although it is always good to take it into account and compare prices for each individual. A very important fact, indeed, should not go unmentioned, is the impressive amount of information contained in its website as well as insightful as they are his subjects. For example, it you can download from its catalog to seek guidance counselor. There is the option to see the price list to purchase a special discount card and even see the mark in advertising and television. Finally, it is one of the best websites in the industry. Here's his website:





In regard to such stores, are most often those that already sell complex products developed to meet specific needs. In this regard the company is Schneider Electric Mexico , which offers electronic products and specialized control for proper use and installation which requires no less than a lot of preparation in the field of engineering. For example, in their catalog are items for the control and management of buildings, protection and network monitoring systems, programmable control and data processing, load centers, distribution panels, switches miniature, safety switches, electrical distributors of low and medium voltages, operating interfaces, relays and timers, switchboard panels, terminal strips, transformers, ultraterminal, soft starters, power supplies, cabinets for many products, low-voltage capacitors , etc. and so on.

As can be seen, Schneider Electric Mexico is a great company whose characteristics and variety of brands and products make it an excellent choice for engineers in each of the branches of electronics, but above all, its usefulness is limited to the workplace, it is unlikely that a top level student need any of the products this company offers, unless a special project warrant the purchase. Schneider is a former and very serious and it was interesting to discover that its history goes back to the amazing year 1836! Here is an example of how it sees its Web site:





Now on later. Electronics firms usually specialize in one of them to provide better services. That's why searching the net is not going to be difficult to find places for special electronics.

If you want something really particular, is a company dedicated exclusively to manufacture and sell computer networking cables. This is good to know as traditional stores probably find only certain things relating to this application of electronics. So if you want something more specific we can address International Electro-Mechanical Systems to address: Av San Antonio 319-110 Col. San Pedro de los Pinos . this field there are also others, which we list below along with address: Surfactants Mexico, Prol. Calle 16 No. 86 Col. Ind. San Pedro de los Pinos ; Foruno Power, Insurgentes Centro No. 11 Col. San Rafael , all in Mexico City, and the latter is engaged in the manufacture and sale of electronic cables in general. Nothing gives your Web page.


In this line we have for the sites that specialize in meeting the need for electronic devices become more specialized. And yet we just do not find very useful pages on the net. Another example is in TRV Electronic Devices which " manufactures equipment for the rational use of energy and protection of individual devices connected to any of our products, problems of voltage from the power distribution line." This is a company located in the city of Buenos Aires, Argentina, which, however, worldwide delivery, and that includes, of course, Mexico. In fact, in his page is the following statement, under the heading "Export"

currently export to Chile and Uruguay with sales representatives and technical support in the cities of Santiago and Montevideo.


Our products are already installed in businesses in Mexico and the United States.

While we are opening channels with Brazil, Paraguay,



Bolivia, Peru and Colombia.

This company is mainly engaged in selling uninterrupted power supplies but also sells other important products. A sample page is:



d) ELECTRONIC DEVICES

As electronic devices are referred to a page that has a great list of devices and its basic features, this page is http://www.ilustrados.com/publicaciones/EpZEEVlylVBCHFYUng.php

Other related sites are:

http://teleserviciodelsur.com.mx/, http://www.syscom.com.mx/empresa.htm, http://alfaomega.com.mx/shopsite_sc/store/html/ product470.html, etc.

e) ELECTRONIC FORUMS

By nature we have seen that human beings are a species too restless, which the abilities and skills which was endowed has become someone who keeps watching, describing and imagining, but that's not all, a feature important

it is that has the ability to give a critique or provide feedback, which have made or have allowed everything that once was criticizing were able to refine or improve.

important part of this research is named "Electronic Forums." To understand the goal we seek in choosing this topic is important to know which is a forum, this definition tells us that:

Ø Forum (Forum). Exchange of information regarding a particular topic or product that is host to an online service.

Having understood the above definition, I believe that we can begin to see the importance of the Internet with pages that give a specific space to the forums, where we as users have the opportunity to some criticism, give some suggestions for improvement, and why not congratulate or express our gratitude for what was found in the network.

In the forums you can find plenty of topics for discussion, then present some of them:

Audio: General Discussion -
Audio: output elements - Speakers, Speaker, Speaker, Speakers, Dividers passive protection system.

4. CONCLUSIONS

To end with this simple research could include that give you a little syntax of all these pages but we could not bring a clear demonstration of what you might find in them, but things could ensure that if is that in these pages you can find them quickly and clear the information you require since the vast majority of these pages have lots of electronic information materials, and not have to waste time entering and leaving countless pages to find just propaganda, a single definition of the subject you want, or information in a language other than English.

hope they will help you as well as a good reference for your development in this beautiful area is electronics.
