Personal Cell Phone Signal Blocker Device
Although cell phones are probably the most useful communications devices ever developed (until now, that is), they do tend to get a little bit on a person's nerves, especially when they are outfitted with some very obnoxious ringtones. And that's exactly the reason why the people over at DealExtreme have come up with the Personal Cell Phone Signal Blocker Device back in August 2007, as this rather unusual product can block the cell phone signal on a 0.5 – 12 meter area around it.

According to the vendors, the jammer uses super-high frequency and mini power interference technology in order to block the GSM signals by interrupting the downlink connections without affecting in any way the handhelds.

It would seem that this device is quite effective, since it can block CDMA/GSM 869-960 Mhz networks, 2110-2170 Mhz 3G networks and 1805-1920 MHz DCS/PHS networks. The “circle of no-communication” created around the device has a variable radius, depending on the type of carrier network and other factors, but, nevertheless, it extends to a minimum radius of around 0.5 meters.

Moreover, the device is not dangerous for the human body (maximum level of emitted EM radiation is less than -10dBm), and requires relatively little power in order to operate, since a full-charge of the built-in 1500mAh battery lasts for up to 3 - 4 hours of continuous use. It's encased in a solid, shockproof metal casing and it's also extremely portable, as it measures around 4.09 inches x 1.85 inches x 0.71 inches (10.4 cm x 4.7 cm x 1.80 cm), at a weight of around 6 ounces (170 grams).

The device presented by DealExtreme retails for around 50 US dollars, which is a rather fair price to pay for such a device, despite the fact that this thing is of Chinese origins, so its efficiency is not exactly guaranteed.

Simple and Versatile Navigation – Tree View

-

The system can present a so-called ‘tree view’ of the Assets Register. The hierarchy of Client, Location, Assets and Parts, etc is presented on screen, enabling you to view all the interrelationships and navigate your way around your enterprise’s entire asset population. The tree view is the most convenient and intuitive way in which to explore and scrutinise the enterprise’s asset population, as well as its organisational structure. And it’s interactive. You also have quick access to the compendium of information held for each location, system and equipment item. You can drill-down to find the information you need; click on any item to view its full details. For example, you can view the asset list at each location, a single asset’s assembly hierarchy down to part level, find out where any particular part is used, who supplies it, the technical specification, see a picture of it – and study any other information filed against it. You can expand or collapse branches to drill down to

Creating Online Portfolio Gallery Tutorials

Times really have changed! Only a few years ago it was par for the course to travel across town (or the country) lugging a heavy portfolio case full of treasured works, or mailing them to a faceless stranger. There was the fear of damage, or worse still, hearing the words, "Can you just leave it here with us for a few days," not knowing what will happen to them as soon as we turn our backs. I have a hunch that the printed portfolio will be with us well into the future. However there is a growing trend to put a portfolio on the web. This has obvious advantages; Your site is up 24/7, it's cheap, can be viewed by anyone around the world and the potential audience is huge. Since launching PhotoshopCAFE.com almost 5 years ago, over 3 million people from around the world have viewed my portfolio, this would be impossible without the web. Photoshop makes it very easy to build an online portfolio. I will show you how in just a few steps and we can do it all from the File Br
