Micromachining

Image
 There are a lot of different technologies that are being continually used today which in tandem ensure that you are able to get things done and not have any problems in figuring things out. There are concepts out there that you might not even be familiar with, but might have made use of unknowingly. It is all these small things that ensure that we are able to live heartily and not worry about small problems that might be irksome. Micromachining is one such technology, thanks to which a lot of things are now possible. Intricate medical equipment The field of medicine is an effervescent one, with changes happening round the clock. Hence, there is a constant need to improve machinery and tools to enable physicians and surgeons to do a better job. There are so many different forms of micromachines at work today that enable doctors to precisely diagnose and treat complex conditions. Hence, Micromachining is making it possible to enable doctors to find and treat conditions with ease th

Internet Security For Children

Image
 It seems that most children in today's world are using computers and laptops and the trend should only continue as computers become more reasonably priced and increasingly important in our society . As a father to three great kids, one of my biggest concerns is the safety of my children while surfing on the Internet . Because of generous relatives, each of my three kids has their own laptop and because they received them as gifts, it would be difficult for me to take them away from them. (Thanks for checking with me, relatives!) So, the laptops appear to be here to stay. My major concern is how do I provide security for my children on the Internet? Because it would be literally impossible for my wife and I to physically watch our children while they are on the Internet, there had to be a means by which they could be observed on the Internet without it being too obvious but yet powerful enough to keep them out of harm's way. So, I took on the mission to find a service that c

Media Center Remote Control - A Device Based on Voice Recognition Technology

Image
 Media Center Remote Control is specially designed for windows media center and the windows 7 operating system, the latest in media center remote controls now offers flexible operations with most functions being activated by voice or buttons. This remote is enabled with speech recognition technology. Speech Recognition Technology also known as automatic speech recognition or computer speech recognition, converts spoken words to text. With voice controlled remote, there are multiple speaker profiles selectable by voice for example say the command: 'this is Smith' and Smiths profile will load automatically. Advanced position sensing software will also isolate the voice of the speaker and ignore any concurrent conversations in the background. Why use a Media Center Remote Control? We can use this remote for a number of reasons, among which some of them are as follows: • Watch, record, control TV with the tuner. • Control, play and rip music. • Create, play and control slide s

Advantages of Digital Systems

Image
 1) The devices used in digital circuits generally operate in one of the two unites, known as ON and OFF resulting in a very simple operation. 2) There are only a few basic operations in digital circuits which are very easy to understand. 3) Digital techniques require Boolean algebra which is very simple and can easily be learnt. 4) Digital circuits require basic concepts of electric network analysis which can easily be learnt. The principal electrical char¬acteristics required are switching speed and loading considerations. On the other hand, analog circuits and systems involve frequency and time domain concepts, complicated circuit analysis techniques, etc. which make the un¬derstanding of these circuits much more difficult than the digital circuits. 5) A large number of IC's are available for performing various operations. These are highly reliable, accurate, and small in size and the speed of operation is very high. A numbers of programmable IC's are also available.

Data Security Over Computer Networks

Image
 When designing a network, data security must be included in the design plan because protecting data while it is transmitted is very important especially if is is sensitive data. Additionally, authenticating users when trying to open protexted pages is also very important to avoid storing data. Finally receiver must assure that the data is received as transmitted. The previous points are explained below separately . When transmitting data across a network, many attackers exist that can intercept the data and read it. The data are transmitted in the form of binary signals. Any one having a detector can read this pulses on the line. The data transmitted can be very sensitive especially in military applications. The solution to the above problem is to scramble the data before transmitting them according to some rules. On the receiver, these rules must be known in order to extract the original data from the scrambled data. This process of scrambling is called encryption. Encrypting d

Ergonomics and Computers

Image
 Its amazing how many people use computers in the wrong way. Simple things like having your monitor sitting at the right height play a huge role in how comfortable you are, especially over the long period. For example, your monitor should sit with the top of the monitor at about eye level. Any lower or higher and you risk doing damage to your neck. So many people have the monitors lower, but if you think about when you stand normally the most comfortable position to look is straight forward, not bent down like that would promote. Having the right height desk, chairs and back rest are also very important. Generally though I have found that it is your wrists and fingers that suffer first, before your back. To counter this, you need to ensure that you are working ergonomically. Get a mouse pad that is customized in a way that is comfortable. Your wrist pads should support not only the wrist and arm, but also the side of your hand that rests all of the time . A good quality pad will ma

Computer Using Behavior

Image
 Computer users, roughly speaking, fall into one of several categories. Here is a brief summation. Extreme Users: Extreme users spend nearly every waking moment in front of a computer and do so voluntarily. These folks are definitely techno enthusiasts. They tend to be attracted to such things as web design, gaming, programming, computer graphics , etc. They use the computer as a tool and as a form of recreation. Their lives are intertwined with the internet. These are people who would be lost without a computer. They always want to have the latest and fastest computer and are willing to pay top-dollar for it. Heavy Users: Heavy computer users are folks who tend typically use computers for a work-related purpose. This alone consigns them to life in front of a computer screen . They spend around a 3rd of their lives in front of a computer. They tend to become adept at using various applications. They tend to develop decent typing skills out of sheer repetition. Heavy computer users ar
