Electricity conservative transceiver by Microchip

Everything is going mobile from the simplest devices to the most complex ones. Following this fact is the demand for long life power backup in order to keep such devices running for long. Developers are trying their utmost to make electricity efficient units to make them run longer on battery. Same is witnessed in the recently announced MRF89XA transceiver. The transceiver is made after keeping the current demands in sight. this transceiver would offer a very minute 3mA receiving current devices that involve the frequency bandwidth of 868, 915 and 950 MHz-Sub-GHz wireless networks.

Architecture Details:

Special architecture has been used in order to make sure that the receiving current is pretty plain and minute. The transceiver has been made in a way as to improve performance and reduce attenuation and other interferences. This way the current is well managed. The design cycles are improved to a considerable degree in order to make it more efficient in the 868 MHz MRF89XAM8A and 915 MHz MRF89MA9A. Previously the circuit design that was implemented in the RF circuit was quite complex that was causing more power consumption. The whole of the RF circuit has been revised and made way simpler. The cost of obtaining agency certification is also reduced that has caused a considerable change in the current.

Similarly, the designers are always attracted by the Sub-GHz to be used in their designs of wireless battery powered sensor network and metering communication so special consideration has been made for the bandwidth range.

The ease in communication and battery life extension has also been ensured by the packet transmitter that is used in the architecture. MRF89XA is having the 64 byte FIFO for transmitting and receive buffering signals.

Technical Advantages:

The manufacturers have not only improved the current aspect ratio but many of the other factors as well. The Microchip’s transceiver are managing current really well that would make sure your device runs longer on battery power. The design has been integrated with power amplifier as well as low noise amplifier that make it even better in terms of performance. The Power Amplifier has a 12.5dBm specification that makes it possible for real long distance transmission that comes as an added benefit. It is also integrated with -113dBm Low Noise Amplifier that ensures greater sensitivity while reception.

Benefits for industry:

The device comes with a lot of advantages on the overall. The first of which is long life. Everything that has turned mobile needs to run long for a convenient and better experience because of the reason that you might not get appropriate time to charge it sufficiently through your busy schedule. The transceiver helps you achieve that through the Microchip Technology.

In addition to this, the integration of Power Amplifier, Low Noise Amplifier also give it added benefits that can be availed in the appropriate way while communication. This would certainly give you quality signals as well as transmission that hovers over a longer distance.

In a nutshell, the Sub-GHz technology that is being well catered in this development from Microchip is the future of wireless technologies so the device is going to help through the phase of network development.

How Digital Cameras Work

Do you remember the limitations one faced using the old film faced cameras, where in one had a limit of clicking standard 32 images, which could be done only after rolling the camera reel, back to the original state after a photo was clicked. A photographer at an even had to carry dozens of camera rolls with him at an event, and the rate of capturing was also slow.

But with the advent in the technology digital cameras were created which instead of using photo sensitive chemical known as film, used charge coupled device (CCD), an electronics instrument that creates a pixel map based on the electric charge generated when photons slam into a sensitive material. This was the Photo Electric Effect, invented by Albert Einstein and was now utilized in advancing a new league of cameras.

This is how it works:

• In the digital cameras, there are a number of image sensors on the array, which are placed across the microchip of the camera. Every image sensor is a charged-couple device (CCD) converting light into electric charges. In it silicon chips are used fundamentally to measure the light. The charges that are created are stored as analog data that are then converted to digital via a device called an analog to digital converter.

• The chip also contains very small light-sensitive diodes which are in a collective. They are called photosites or pixels. They convert light into electrical charges called electrons. These pixels are light sensitive, so when brighter light strikes them, it produces a greater build up of electrical charges. Thousand such array receptors create one pixel, and every pixel corresponds to some information stored.

• The light enters the digital camera via the lens, same as it is in the conventional analog camera. When this light hits the disc the shutter opens and thereby illuminates every pixel, however with various intensities. Each pixel is combined after the computing on the microchip where the stored information is gathered and an image is created. This created image is transferred to memory cards of the Digital Cameras. The memory cards can be of varied memories ranging from 512 Mega Bytes to unprecedented limit of 16 Giga Bytes.

• A cameras resolution is rated in mega pixels, which are in turn the pixels of data gathered by the lens on the microchip. More the number of pixels more are the resolution. With the increase the mega pixel number the price of the camera also ascends vertically. But you don’t need to worry as cameras of good resolution come in economical range and are viable for good prints. The digital cameras have allowed the users to no need to go and get each roll published and then creating an album which utilizes space and get affected by natural conditions too. Now they are in digital formats and stored on your hard disk or even uploaded on internet.

The digital cameras with increased memory life and increased memory have increased the range of its usage, and made it more viable and economical for a common man to buy it and use it efficiently.

FIFA's "Smart Ball" Technology

There are many football fans across the world that may not know that in FIFA the football is not just any other ball made out of leather, but an intelligent device in itself.

Recently there has been a buzz in the media, whether the football will be laced with gadgets inside it to provide real-time data at the 2010 FIFA World Cup in South Africa. 

Commonly the technicians of the World Cup call it the “smart ball” or the ball that provides accurate inputs to the referee and game strategists alike.  It may well be decided two or even three months before the big game whether the smart ball will be used this year.

However for the time being, let’s talk of the interesting “nitty grities” of the so called “smart ball” first. To put it in simple terms, the “smart ball” is laced with a micro chip inside, which provides data such as; whether the ball has past the goal line, current location of the ball in respect to field view, statistical input, etc. These are just some of the details that are provided by the microchip. It’s from the various functions itself that you can assess the “smart ball technology” is an integral part to resolving all conflicts that may occur between the referees and the players.

Apart from the expensive broadcasting rights, which is the only technology that is ever discussed about in any FIFA world cup, the “smart ball technology” provides an interesting insight as to what really goes on to the making of the game.

The Future of Android on Netbooks

It is still too early to determine the real fate of Android on netbooks? But one thing is clear – it is coming and when it does, people will soon know whether its future is gleam or bright moving forward. Many have envisioned 2009 as the year of the Android netbooks but perhaps it will most likely be in 2010.

Originally used as a mobile phone OS, Google’s Android has been conceptualized to penetrate the netbook marketplace because the company clearly has no plans of limiting their crafty mobile OS in smart phones alone. Android has even fortified two policies of its uses: one is its use in phones and the other is on MIDs or mobile internet devices. The popular ASUS netbook is one of those MIDs. As confirmed by Bloomberg, ASUS has already mobilized some of its engineers to look into the use of Android in their computers. In this regard, it is noteworthy to mention that Daniel Hartmann has successfully installed Android on the ASUS Eee PC 1000H.

From Venturebeat news, there seems to be some trustworthy claims that Intel has already designed the correct drivers for the said MID devices. And that the microchip giant has already planned on mass producing Android netbooks that can surface sometime within 2010.

The direction of this open source trend is that it may end up directly competing against another giant in the realm of software – Microsoft. The dawn of Android netbooks will also imply an increase in netbook sales overall, as these devices are expected to come at a much cheaper price than the netbooks powered by other prominent OS like Windows 7 for example.

Even Google’s CEO Eric Schmidt claimed that Android is leaning towards a very healthy market and that he already knew of Android’s open source nature where various devices can be used for such. In addition, he was also very excited upon knowing that some people have experimented using Android for netbooks as a preliminary try and Android netbooks is indeed a very exciting investment to be in. Yes, Android allows for good computer experience even at low resolution scales such as in cell phones. It can be used to run some basic computer processes as well. Nevertheless, it is Android’s web browsing functionality that gives some sort of standardization goal among netbook users nowadays.

However, considering that other OS like Windows 7 has been engineered to be compatible in netbooks and because people have already been using the more stable or dominant OS platforms for many years with fewer qualms, then the best advantage for Android netbooks is probably its lower price tag. Further, Google may also be eyeing into newer computers – the portable tablets.
