IS THERE A BLESSING FOR THE SAR?

In a scene from the musical “Fiddler on the Roof“, the Jews of Anatefka understanding that Judaism has a blessing for everything ask the Rabbi “Is there a proper blessing for the Czar?” He pauses and then chants: “May God bless and keep the Czar… far away from us!” Although the spelling and the meaning may differ, the principal is the same. ‘Keep the SAR far away from us’.

“SAR”, an acronym for Specific Absorption Rate, relates to the body’s absorption of radiation emanating from a mobile phone. Intermittently, we hear frenzied concerns that cell phones cause brain cancer. Studies to date have proven largely inconclusive. Accordingly, I have not found them convincing one way or the other. Remember, however, that the cell phone has only recently become a part of the daily routine of such a large portion of humanity. We will know a lot more in 30 years, but by then, many of us may already have suffered irreparable damage. Don’t forget that people did not consider cigarettes dangerous to health for a very long time. While I intend to monitor the results of future studies, prudence suggests implementing some precautions in how we use our cell phones. bronchitis cipro

In the US, the FCC imposes a SAR limit of 1.6 watts per kilogram (”W/kg“) over a volume of 1 gram of tissue. Europe uses a standard of 2W/kg averaged over 10 grams of tissue. Many phones have come out first in Europe and then later in the US.

For some time, people have purchased unlocked GSM phones in Europe and brought them back to the US. If you wish to reduce exposure to SAR, you may want to wait until new models come out here.

The theoretical danger comes from the fact that basically, the RF waves ”cook“ tissue by heating it. While use of the cell phone held up to your ear for short periods of time may pose a minor risk, logic dictates that, if the risk exists, the longer you hold the phone by your ear, the more likely that brain tissue near the ear will suffer heat damage. Does this mean that we should all dump our cell phones or that the Surgeon General should require a warning printed on the back of the phone? Probably not, but, common sense suggests that we should exercise some caution. RF waves dissipate over distance. The farther that we keep the phone from our body, the less likely that it will cause any problem for us. Using the phone’s speakerphone and keeping the phone on a desk or table when you talk offers one way of reducing exposure. As Bluetooth uses a lower power, it poses a smaller risk and, therefore, using a Bluetooth headset and keeping the phone in a brief case seems prudent. A wired headset does not generate radiation, but generally results in keeping the phone closer to our bodies.

Selecting a phone with a lower SAR also should reduce the risk of exposure. CNET has a nifty chart showing the 10 highest and l0 lowest SAR rated cell phones in the US and also providing information about other phones on a lookup basis. You can access the CNET chart at http://reviews.cnet.com/cell-phone-radiation-levels/?tag=lnav. I found it somewhat surprising that there appears little consistency within manufacturers and that some of the highest SAR phones had siblings in the lowest category. depakote numbness

Battle for Haditha movies According to CNET, the representatives in the highest category include several Motorola phones, one from Samsung and two versions of the Blackberry Curve.

The 10 lowest included phones from Motorola (two iterations of the Motorola Razr the Razr V3x and Razr2 V8), five phones from Samsung and two from Nokia. The Palm Centro models ranged from 0.74 to 1.35 W/kg, while the Treo models ranged from 1.26 to 1.5 W/kg. The original Apple iPhone came in at 0.974 W/kg and the iPhone 3G rates a 1.38 W/kg. Memory size appears to have no impact on the ratings. The Blackberry Pearl models lists at 1.22 to 1.48 W/kg.

A Bold New Blackberry

The Court Jester hd

I have been playing with Blackberry’s new Bold for a month or so. I am very impressed with it. For my money, when it first came out it was the best piece of hardware released to date by Research in Motion. It remains an excellent telephone, but in my opinion eclipsed by the Storm, released shortly after the Bold. I will write about the Storm later.

The Bold does everything that previous Blackberry devices did, only better in most cases. The size and shape of the Bold does not radically differ from the last generation of devices, but it has a finish that looks more substantial and professional than the plastic-cased Curve.

The Bold comes with built-in GPS, a 2.0 MP camera, Blackberry Maps, video recording capability, Wi-Fi, the standard compliment of PDA programming (calendar, contacts, etc.) and handles mail with the typical Blackberry aplomb. It also provides excellent telephony (including a built-in speakerphone), SMS/MMS support and plays MP3 music.

Without a doubt, the Bold’s biggest upgrade relates to its display. The display has a half VGA resolution (480 x 360 pixels) and uses a backlit transmissive TFT LCD screen. The display is bright, deep and rich. I judge it as far and away the best display on any Blackberry as of the release of the Bold.

The Bold has a full qwerty-style keypad and I like the touch, feel and size of the keys.

The Bold initially came out only on the AT&T system and works with the AT&T Edge network to provide reasonably fast Internet support. It is a GSM phone and should prove to be “unlockable”, allowing you to use it with other GSM systems throughout the world once you have an unlocked unit.

RIM claims 4.5 hours of talk time and 13.5 hours of standby time for the Bold. Because of the way I use and test phones, I have never matched the amount of talk or standby time on any phone that the manufacturer claims for it and the Bold is no exception. I have no problem getting 2-3 days of use between charges though and that works fine for me. My Own Private Idaho move

Rim Storms Ahead With Its Newest Blackberry

Blackberry Storm

Last week I wrote about the Blackberry Bold, identifying it as the best piece of hardware RIM (Research in Motion) (www.rim.com 007 Casino Royale film ) had produced to date.

I also noted that the Bold’s tenure at the top lasted about as long as a full moon, since RIM released the Storm shortly after the Bold. As good as the Bold is, I like the Storm better.

Why do I prefer the Storm? First of all, it provides all the services and capabilities of the Bold and more. It’s included camera produces 3.2 megapixel stills (compared to 2.0 for the Bold). The camera includes automatic flash, automatic focus and a 2x digital zoom.

The Storm also does videos, plays music, handles text messages, does email as well as any Blackberry device ever has (and I have thought Blackberry did the best job with email of any PDA or multi-function phone for some time).

Other features include built-in GPS, Blackberry Maps, SMS/MMS, Bluetooth and Micro SD card support. The phone works on Verizon’s 3G system (you can only get it with Verizon service for the present time).

Because it works on the 3G system, downloads run fairly quickly.

The large (3.25“) transmissive TFT LCD display supports over 65,000 colors and produces a resolution of 480 x 360.

What really sets the Storm aside, however, is the new SurePress touch screen technology employed by RIM in the device. The Dark Half download The Storm has no physical keyboard, no dial and no trackball. You navigate by pressure and motion on the touch screen. Although the screen presents a solid surface, when you press it, you feel a physical click response as confirmation of the completion of the contact. The large icons and virtual keys make it pretty easy to get around and to use the keyboard. The technology offers a lot of cool options as well. Deception movie download You can use the Storm in landscape or portrait mode. If you use it in portrait mode while making a phone call, you get a virtual telephone pad. If you use it in portrait mode while performing a text function (such as email), you get a keypad similar to that on the Pearl (2 characters per key) and relatively small keys. If you turn it to landscape mode, the Storm senses the position and gives you a full virtual QWERTY keypad with large keys.
