How Does Rgb Led Technology Work

RGB LEDs basically contain three LEDs used in one. The combination of these three colours covers the full spectrum of colours. The RGB controller works with PMW (pulse-width modulation), which means at a certain frequency it turns the LEDs on and off fully (this is exactly the same technique single coloured LEDs are dimmed). If you turn the blue LED off completely for instance, the red and green will create a yellow light together. The colour can be manipulated with the frequency of the individual LEDs on and off modes. If you add a bit of blue to this yellow, you will receive a lighter green shade. To create a single colour output the frequency of the full LED must be over 50Hz.

So, what is the full range of effects possible with RGB LED strip lighting?

The simplest RGB LED string lights have a pre-programmed set of colour they can emit ranging from four to 16, and the colours rotates according to these programmes. The range of colours displayed can be widened with the knowledge of the strip and obviously the knowledge of the controller. RGB LED ribbons which allow DMX controllers can display several million colours. Besides the regular RGB LED strip lights which can emit several shades of colours, but only one at a time, exist the multiple colour strips also called magic LED strips or pixel LED tape lights. This type of RGB LED rope light requires a special RGB controller. RGB LED strip lights are most often sold with the controllers suitable for their operation, or there is a list of recommended controllers indicated at the strip lights description. Controllers can basically be manual, automatic, semi-automatic, pre-set sequence or DMX.

Besides the most commonly used pre-set sequence RGB controllers, a popular solution for creating your own effects is DMX controllers, which allow users a wide range of settings of the brightness, the colour and the pace of colour changing of the strip light. DMX controllers allow you to set the level of brightness, usually have a range of colours over several millions, different speed of display or colour change, this speed can often be set to follow the rhythm of music. With this wide range of possibilities to create your own, unique lighting, only your imagination is the limit.

Ways Auto Navigation Systems And Gps Technology Helps Improve Our Lives

GPS is used in most of today’s GPS and car navigation systems. The truth of the issue is that this technology while once reserved for the well to do is nowadays trickling into the middle class.

Today we are observing this technology in mobile phones for a variety of locational uses and functions. We are observing this technology in vehicles in order to track and perhaps retrieve them if they are stolen. We are also observing this know-how used to help lost pets discover their way back to the homes of their families. The fact of the matter is that there are many ways in which GPS technology is presently making our lives easier.

Below you will find a great number of uses for GPS and automobile navigation system technology that presently exist. Even more amazing is the fact that newer discoveries for these technologies are being made each day and over time there will be an even greater diversity of methods to utilize this know-how for the benefit of the general public.

This know-how can not only trace the position of your vehicle but in addition be used to call for assistance in emergency situations. This device is activated by the press of a switch and can even be used by little children in crisis situations.

There are a lot of ways that GPS and vehicle navigation systems and know-how are being used each and every day to improve our life and provide peace of mind. The methods brought up above are simply icing on the cake.

The Ipad Is No Flash In The Pan Technology

Here is a newsflash – Apple’s IPad is here to stay. This handy little tool has taken the 2010 computer industry by storm…in a down economy no less. Steve Jobs and Apple are currently unmatched when it comes to finding and attacking new consumer markets. While other IT giants are putting most of their efforts into defending their current status and following other companies in sectors that are already near saturation, Apple continually innovates and creates a market where one previously did not exist. Whether it be ITunes, the IPhone, or even Macintosh computers (which refused to bow down to Microsoft Windows as the end-all-be-all in home and professional computing), Apple is a leader – not a follower. The IPad is simply the latest product in this legacy.

There are a myriad of reasons why the IPad is so popular. However, the #1 reason is its ease of use and well targeted functional focus. While not an overly powerful hard drive, the IPad has all of the functions that the casual computer user needs and few that they typically do not. Its features of a clean fast operating system, easy to use touch screen (complete with pop-up QWERTY board), and emphasis on media usage has made it a hit with users of all ages. At $500, it also sells at a lower rate than most modern lap tops, although lower end models from most major retailers do come in below the Apple price. With fall courses starting across the country on college campuses, the IPad is selling like hotcakes to the younger generation.

There are a few drawbacks to the IPad. As far as computing power goes, it is very limited. The touch pad keyboard is not going to be a hit with users that are frequently using word processors or heavy programming. It is also a bit of a tweener when it comes to size. It is too big to fit into your pocket, but not big enough to feature a large widescreen and full keyboard (with number keypad) that is common in the most popular laptop models today. More experienced users will also find issues with the system’s networking capabilities. There are also some issues with what happens when the product has problems. There have not been many common issues yet, but eventually every technology has issues (even Apple computers). How well the IPad is able to adjust to those on the fly will prove important. Ultimately, it is about knowing your computing needs and weighing those against the products specifications and capabilities.

But people who need these programs extensively are not the target audience. Apple simply realized that most computers offer more power and more features than the average person will ever need. The days of users frequently needing to add to their hard drives and clear space to make room for new applications is (for most people) behind us. For people who use a computer primarily for media (internet, music, movies) or just need a simple OS for their computing needs (i.e. college students), the IPad is proving to be a terrific option with few drawbacks. Apple has done it again.

The Digital World Is Embracing Mobile Technology

Introduction of new and advanced technologies have brought a great revolution in the digital world. The technology of mobile comes under such great technologies. The use of mobiles is no more limited to the deliverance of personal messages. The advancements in mobile technology and their uses have surprised us to a greater extent, both negatively as well as positively.

Mobile technology has played a dynamic role for education. Students can access Internet through the great technology of mobile broadband. This permit students and researchers to do research whenever and wherever they want.

Observing the way of giving out news, mobile technology now allows us to get breaking news as soon as possible. An individual can now make quick and informed decisions via real time information by mobile technology. The amazing features of Wi-Fi and GPRS have provided the facility of using Internet anywhere and anytime.

As far as the global commerce is concerned, mobile technology has allowed us to market the data we require, by using our mobile phones. Besides that, the introduction of 3G technology has developed the way of conducting business by introducing the characteristics of video calls, sharing large files and browsing the Internet. Among other developments, Promotion of products and brands via mobile is becoming very much active in the world. It’s one of the prominent developments in business in the digital world. It has been found out that the Web and Mobile Marketing are the most productive marketing sources in the digital media.

It’s been expected that the total global IT would increase by nearly six per cent this year. This is expected to happen by means of mobile and other social technologies.

It has also been mentioned in a research that the technologies are finally being integrated with each other, such as cloud with mobile, mobile with social networking, social networking with big data and real-time analytics.

Thus, with the increasing number of masses using mobile technology, projects are reaching a wider pool of prospective clients. On the other hand, mobile banking has let the bankers live an easier life as the convenience in transferring money saves a lot of time.

Mobile technology has become a great helper of people in emergencies as well. According to a research in 2009, 71% of men and 77% of women used their mobiles in their emergency situations.

However, if the proper precautions are not taken regarding the use of mobile technology, one can face a great loss personally as well as in other means. Among many others, one true example is the exposure of valuable data to unauthorized people. Care should be taken for the security of data.

The use of the developing mobile technology depends completely on an individual and the society. It’s our responsibility to make a positive use of this technology. When used negatively, it has a great power to destroy a good part of the world and when used positively, it has the greatest power to let us move ahead and get more advanced in the world of technology.

The Possibilities of Internet TV With Live Streaming

One of the most innovative products that we have seen today is no other than the internet television. Is it really possible to watch TV through the internet like cable TV does? First and foremost, what do we mean by internet live streaming? Well, this is the ultimate way to enjoy watching TV on your PC or laptop. When you download various software programs, you will see a number of channels across the world in various categories including news, movies, music, sports, shopping, and a lot more. You can enjoy lots of channels in your PC or laptop whether if you’re from United States or anywhere in the world.

For most of the 20th century, television programs can only see through the air broadcasts and cable signals. With television, radio waves are received by the antenna to transmit sound and pictures on television. The ones with the cable feature, they were used on the TV itself or in the decoder, which runs from your house to the nearest station cable TV. It also serves as a very large antenna for them. Among the alternatives, cable and broadcasting continues to be the main method of watching television.

They were engaged in providing entertainment and news has been altered by new technologies. Most publications were also challenged by the radio in the 20th century, while the radio is being challenged by TV networks. It seems that the traditional television is being challenged by the so-called “internet TV live streaming. In simple terms, it is an act of delivering audio and video on a computer through the internet connection. It is also called the IPTV or Internet Protocol Television. Therefore, you may watch internet TV in your computer, mobile device or TV screen. Internet TV has the same as getting television through a series of cable wires throughout the antenna. The information about internet TV was transmitted as data over the internet. You can also find a greater variety of TV shows online compared to cable TV.

Among the many performances given by the network, there are many websites that focus on programs about an individual or group of people with similar interests. If you want a cooking show as an example, it is likely to be found without problems or difficulties in a mainstream TV network. As there are many websites dedicated to the service on demand, there’s no need to monitor the program on schedule. However, for sites with a broadcast streaming video or real-time web casting, it should be live in good condition.

Live streaming through internet TV is really new and hot on the market today. Because of this, there are many ways to get it. The good news is the price, quality and even the content can vary with each other. It is just that there is something which gives you the perfect choice. The internet technology reminds us on how we spend our precious time in relation to poor quality watching. With internet TV, we will rise from the couch with no doubts and start moving on.

The Principle Of Retinal And Iris Scanning Technology

Fingerprint method can be misapplied. This reality is proven scientifically correct. For that reason, people then try to find the more reliable biometric systems.

The retina is part of the eyes that is responsible for the ability to see. The pattern of blood vessels that forms the retina is as unique as fingerprint. The principle of retinal scanning technology is scanning the pattern of capillary blood vessels on the retina with low-intensity light sources.

In 1987, the first retinal scanner was made by Leonard Flom and Aram Safir and has been patented. However, by the year 1994, John Daugman developed the technology of iris scanning as a competitor for retinal scanner.

Retinal scanning principle

Retinal scanning is based on the fine capillary network that meets the needs of oxygen and nutrients to the retina. These blood vessels absorb light and can easily be visualized with appropriate lighting. To that end, the close distance between the eyes and a scanner is needed. The appropriate position of eyes toward the scanner is also necessary. Also, there must be no eye movement, such as blink or glance.

Retinal scanning can not be 100 percent accurate. It is also less suitable as a security tool because even though the pattern of capillary blood vessels of human beings’ retinas cannot change generally, but diabetes, glaucoma, and cataracts can change it.

Iris scanning

In its development, retinal scanning is considered to be too disruptive in the case of security detection devices. In the use of retinal scanning, the eyes should be as close as possible with the scanner. For long-term, the light of scanner that is too close to the eye can give negative effects.

Because of the weakness, iris scanning technology emerges as strong competitor. Iris, a network that gives color to the eyes is also unique in which the chance for two identical slices is 1:1,078. Even, the left iris and right iris of someone are different.

Online Information Technology Learning Programs

The technology behind computers has evolved to the point that almost every business and organization utilizes it. Students that complete information technology training are able to step into a wide range of careers. Online colleges offer students several programs and concentrations that will prepare them for the industry.

Education is available at every level including the option to complete a certificate program. Students are taught to work with a businesss technological component to ensure accessibility and security. With the high level of information stored within a businesss computer system professionals are used to manage the entire network on multiple levels. Online education provides students with a variety of opportunities to enter careers in information technology. Possible areas of study may include:

  • Computer Information Science
  • Computer Information Systems
  • Information Security

To understand what these educational opportunities teach students should research the field of information technology. Concentrated programs are usually available at the undergraduate degree level. Many students that seek graduate training complete information technology degree programs. Exploring the field will give students an idea of what professionals do within different careers.

Certificate and associate’s degree programs in information technology give students the basic skill set to enter careers as technician specialists. A broad understanding is gained inside certificate programs. Computer operation, programming, and system manipulation are some areas of study that may be included inside a program. Some colleges offer students the chance to use certificate and associates degree programs to gain a wide knowledge base that can be used inside a specialization. Online education in website design, technical writing, and information architecture are some areas available to students.

The ability to help computer users solve problems and examine technological needs can be gained inside a bachelor’s degree program. The availability and security of data within a framework of IT services is the goal of understanding the different components that make up the industry. Networking, application development, and digital media publishing are some subjects integrated into a four-year bachelor’s degree program. Students should be ready to complete around 130 credit hours that involve general business, English, and math courses. Specific topics prepare students to work as hardware analysts, programmers, database managers, and more. Students learn how the structure of data is created and how to efficiently manage an entire information system.

Pursuing education at the graduate degree level has students studying advanced technological components and allows them enter careers as managers. Distance learning master’s degree programs have students developing projects where they learn how to set up networks online that are usable and controlled. Systems development, risk assessment, technology management, and multimedia configuration are some program topics that help student’s transition into careers. Empirical research and leadership skills are highly stressed within an online PhD program. Complicated technology systems are studied such as supply chains, information processing systems, and manufacturing systems. Students explore the deep connection between technologies and the businesses economic endurance. Upper-level positions exist for students that complete graduate training.

Students have many accredited educational choices to choose from to begin careers in information technology. Full accreditation provides proof of a quality training program. Agencies like the Accrediting Commission of Career Schools and Colleges of Technology are approved to accredit qualifying online information technology programs. Once an area is selected students can study the necessary skills to become working professionals.
