Powermat – How Does the Powermat Wireless Charger Work?
Powermat – How Does the Powermat Wireless Charger Work?
PowerMat is an exciting new wireless charging technology. It was first demonstrated in 2008 and early 2009 and is now available to buy for the home and office.
So what is PowerMat? It is a small device that uses wireless charging to charge your most important gadgets like cellphones (including the iPhone and Blackberry), video games (including the Nintendo DS), and iPod without you having to connect them to a charger or plug them into the wall. The PowerMat itself is, of course, plugged into the wall and connected to mains electricity by a wire, but from then on everything is wireless. You drop your device onto the PowerMat and it gets charged wirelessly, without you having to do anything.
So how does PowerMat wireless charging work?
The technology behind PowerMat is known as ‘electromagnetic induction’ (or just ‘magnetic induction’). Michael Faraday is generally credited with the discovery of the induction phenomenon in 1831 though others were working in the same field at the time.
This electromagnetic induction is officially defined as “the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field” but that does not mean very much to most people. A better way to put it is that it is a means to transfer electrical power using a shared magnetic field.
Consider this arrangement:
1. Put electrical power into a coil of wire
2. This will produce a magnetic field around the coil that affects any metal within the field (as demonstrated by Faraday)
3. Change the field quickly over time and an electric current will be generated in the metal
So what is happening when a PowerMat is charging is that it is generating rapidly changing magnetic fields above the mat; these are converted by receivers on any devices on the mat into electrical power, and so these devices get charged. The magnetic fields and electrical currents are, of course, very small and so they can work on handheld gadgets without being a health risk to humans.
The same technology is used in a huge number of other devices and systems including generators, motors, transformers, some cookers, induction welding, and so on. Perhaps to most people the best known example is in rechargeable electric toothbrushes, where they are familiar with dropping a toothbrush into a ‘dock’ daily to keep it charged. However they may be unaware that similar systems are also operating in electric guitar pickups, video tape players, and computer graphics tablets.
PowerMat is currently the best known example of a wireless charger but this technology is developing rapidly and soon we will see it in many other applications and products. The PowerMat company itself is planning to extend the technology and feature it in kitchen counters, walls, and other surfaces around the home. One day this technology may be used everywhere and be invisible, it will be so commonplace. Finally we will be freed of the endless tangle of chargers and wires around the home.…
As the title indicates, this article is about the new gaming console that is starting to get a lot of buzz on the highly anticipated PlayStation 4 and what features it is most likely to have and also a closer look at when it might be getting released.
Due to the increased demand for gaming devices, a number of advanced consoles have hit the market recently, but the play-station consoles have impressed almost everyone. They have left long lasting impression on the mind of gamers in various parts of the world. They are equipped with ravishing new features. With these gadgets, users are capable of storing several other online games. They enable you download music, movies, images and a lot more.

DJ has become quite popular since last few years. The people just love the DJ. They just want to enjoy while the music is played. No one can stop themselves from dancing. They all just love dancing. The DJ headphone is one of the most important gadgets in the whole DJ system.
Just a few years ago, Wii took the gaming system world by storm. Before that time we couldn’t imagine a gaming system where the movement of your hands and arms controlled the action. in You simply turned on your console, loaded the game of your choice, grabbed a controller, and you controlled the action. The only thing is that Wii seemed to be catered more towards kids, rather than adults. Well, a new guy is in town, and he goes by the name PlayStation Move. The PlayStation Move works with the PlayStation 3 system and a device called the PlayStation Eye to pretty much do the same thing the Wii does, only better. Plus, this is a gaming system for children and adults alike.
The release of the Wii brought with us the current trend of motion controls and currently Sony and Microsoft are making their own versions of it. While the motion controls for the Wii have given us several great tools to use in our lives like the Wii fitness which helps people get in shape, how does the trend of motion controls impact the part of society that has some form of disability?
In the modern era, gadgets come in various sizes and shapes. Some of the devices are used only for the entertaining purposes while others are considered as tools and requirements. The devices like televisions, laptops, computers or many others have been used by the people in their day to day lives. Such cool gadgets have made our life simple and easy. Many of the outstanding and breathtaking devices are only meant for the special occasions.
Quite a few commercial establishments engaged in the food industry retain a level of top quality handle inside manner their foods are cooked, with controlled level of materials and methods as well. One may well wonder as to how these recipes are continually recreated using the exact same output. These recipes that the foods establishments maintain at a consistent level need certain equipment to constantly offer controlled heat and equal distribution to the meals becoming cooked.
