Hey fellas,
Its been a long wedding season and still going. Eid ul Azha is near. So it will be a busy winter.
I have been away for over a month now. Attended a lot of weddings. I am still out of touch from a few friends of mine. Anyway, just got back on my laptop so I thought to punch in a few lines.
Its getting cooler now as we are in the winter season. I hope thngs turn out real good this winter. The country is really facing some hard times. But it will be fine very soon, I Hope. I will be rearranging and managing my blog in the next few days. Still there will be posts covering the same topics that I had done. But there will a few new ones as well. I have a feeling that you people woulf like them. I will be categorizing stuff as well as distributing and feeding it so that I can share the word. Feel free to contact me and push in your suggestions.

It has been quite some time now. Rejuvenating, taking long naps. A lot of medicines from some time and IVs. But anyway now I am feeling much better. My family and people around have really helped me a lot during this time.

So I am active again and one thing that I have learned during the last few months is that thinking about your illness, your short comings and your disappointments will do nothing but drive you crazy. Thinking about all these different things again and again wont help. One thing is that you accept what has been diagnosed. You have to face it. Not accepting that you are having some disease and later not accepting that you have to give time to yourself and to the healing process. Fight your illness but dont get yourself entangled with its thoughts. Accept that you have to spend sometime with it or even some people have to accept that they have to live with it.

Make your checklist of daily habits. Try to enjoy your life with in the social and regional boundries that differ from person to person. Try adding things that sooth your mind, your body and a little bit of exercise.

Its a long talk. I will just keep the rest with myself to be posted sometime later. I am just happy that I am back here.  I am positive that I will be posting in routing now.

And one more thing HAPPY RAMADAN to all.

on a leave for a few days. Not well. See you all soon in few days.

Okay. It was a highly anticipated movie. To be released on the 24th june, 2009. I could have waited to see it on TV but watching this type of a movie on a small screen is like throwing away the experience. I grew up watching transformers and so the movie market is not only the kids but people like me also. We had to buy tickets a day before as almost all the shows had been full houses. So now let me tell you about the movie now. I would be rather going for the positive review. First of all the bots – all of em – were amazing and the action sequences, the effects, and the explosions were really awesom. The story – well such kind of a movie does not need a very strong story but its not at all bad. I would not be going in much of a detail but the films picks up where it left in the first part, a couple of years after that to be exact. Autobots are with the humans and they take on decepticons. The Humans as always has been only the US people, but anyways as it is a Hollywood film. The voice of optimus prime is heroic as always. Sam is in the center of action as was in the first movie. Megan fox has looked good, well she wasn’t the center of attention exactly as the effects were too good and the corvettes were splendid.
So on a whole it is a big screen experience and if you are a transformers fan, you are in for a treat.

It is very clear that Internet security on PCs of today is very important. Many PC users keep trying to find a well built pack that would set their worries away, but it’s rather difficult since each security suite comes with its own list of services and the running of each application comes with a smal requirement from system resources. Not all security suits offer antispam security or accurate real-time protection. This is where Yoggie Internet Security (presented at CES 2008) comes into place – it works as a filter for all incoming or outgoing connections. It’s a Linux set-up – a computer in miniature – that connects to yours through an USB port and acts like a filter for the internet connection. Of course, it comes with specialised drivers that redirect all the network traffic through the USB stick. The stick works like a tiny computer: it has a CPU and memory that are checking the e-mails and files from your computer in order to keep your computing activities safe. It’s needless to say – you can uninstall the software internet security that you are currently using if you decide to buy this gadget ($100) – you just plug it in and then forget about it – it updates itself through the Internet connection (you get a 3-year subscription) and the security settings can be customized.

PAKISTAN vs SRILANKA – 1st Test at Galle

Sri Lanka 292 and 0 for 0 trail Pakistan 342 (Yousuf 112, Misbah 56, Kulasekara 4-71) by 50 runs

Mohammad Yousuf marked his return to official cricket with his first century in Sri Lanka, a serene innings that lifted Pakistan from a precarious 80 for 4, and put them two runs ahead of Sri Lanka’s total by the time he finally got out. Consequently Pakistan were in considerable control of a match that see-sawed for the first four sessions, with neither team claiming clear ascendance

Power over Fiber

A low-level power transmission system based on laser light conducted through fiber optics promises to reduce the risk of interfacing to physical communications channels on the electrical grid. The system, available now and referred to as power over fiber (PoF) by developer RLH Industries (RLH), provides practically infinite voltage isolation capability between a central office in a telecom network, and a high-voltage transformer substation (see Figure 1). According to Jim Furey, Senior Design Engineer for RLH, this increases the protection from hazards associated with ground-potential rise (GPR), which is common to high-voltage zones such as those surrounding power transmission equipment.

 Figure1

Utilities may lease communications lanes on their infrastructures to communications providers, as well as for their own system-management functions, such as supervisory control and data acquisition (SCADA). It is often necessary to interface such grid-based networks with conventional telecom networks. In cases where conventional ac power is unavailable, and options such as solar or wind power are not practical, this could mean running copper data lines directly to substation equipment. However, such installations are particularly prone to GPR hazards.

To preclude these hazards, the PoF system enables the copper-based data link from the telecom office to terminate into a remote fiber-optic modem. This modem then receives power (and sends and receives data) at a safe distance from the substation via optical fibers (see Figure 2). The all-dielectric nature of these optical fibers provides an electrical isolation across their entire length (unlike galvanic isolation, which is restricted to the insulation barriers within a transformer).

Figure2

The basic PoF system consists of the Tx unit (see Figure 3), located at the substation, and the Rx unit (see Figure 4), located at the remote fiber-copper interface. The two units are linked by three optical fibers. Two fibers transfer the power, with each fiber forming a single power channel for each of the two continuous-wave 830-nm laser diodes in the Tx unit. The third fiber transfers a power-integrity feedback signal from a conventional LED in the Rx unit to a conventional optical receiver in the Tx unit.

According to Furey, the PoF’s energy-transfer efficiency is low because the technology is new, and the main purpose is safety, not performance. The lasers in the Tx unit consume about 48 W in order to deliver about 720 mW at the Rx unit. While power losses increase with fiber length, useful power is still transmitted at the maximum recommended fiber length of 1500 feet.

Furey also states that the lasers have a narrow operating temperature range that requires both active heating and cooling systems onboard the Tx unit. Therefore, the ambient system operating temperature for the Tx unit is from 0°C to 35°C. A more robust version with an ambient operating temperature range of -20°C to +55°C is under development.

Furey states that each of the two energy-carrying optical fibers feeds a respective photovoltaic power converter (PPC) in the Rx unit that produces an output of 12 V. The two receivers are tied in series to generate 24 V at the output. The outputs of several Rx units can also be tied in series or parallel to produce even greater output voltages or currents, respectively.

RLH recently filed the patent for PoF technology, and four evaluation units have been successfully deployed and in service for over a month. According to Furey, the primary application is for powering RLH’s fiber-optic telephone cards that require low power in remote locations without access to grid or portable power. It is certainly interesting to note a certain parallel in history. Specifically, after Bell Labs invented the transistor, it envisioned the sole application of this device as a replacement for the mechanical relays in automated switchboards, to be used exclusively in their own telephone network.
