Japanese mobile carrier DoCoMo, has launched three smartphone smart jackets which will probably never see the light of day and are so gigantic it would seem to be quite useless in today’s compact portable on the go culture and should probably be called smartphone parkas.

The first addon measures your body mass index and muscle ratio via four electrodes on the sides combined with your personal data like age, sex, weight, height, etc. You can also store your friends and family’s statistics and compare them. The last time I saw this technology it was in my local dollar store.

The second one is designed for women, it measures UV rays to let you know where and when it’s safest to get a tan. It also works as a breath analyzer, measuring the alcohol units in your breath, but also checks to see if you need to chew some minty gum before you talk to someone. First of all, any UV during direct sunlight is going to be bad. If you’re wearing sunscreen then really, you’re just killing yourself faster.

The last one may be only one worth releasing to the public, especially in Japan – it measures radiation in the air by using a semi-conductor sensor. How accurate it is, how often it needs to be calibrated, and how expensive it will be is still unknown. Way to go DoCoMo.

The key factor that differentiates the Fujitsu Arrows Tab from all other tablets is that its rugged and runs Android 3.1 Honeycomb, of course, is its not the only ruggedized Android on the street.   Competition is good. We heard rumors about the Arrows Tab being waterproof, but it looks like it’s all set up to be military-level spec to battle the bumps and bruises that it’ll surely experience along the way. It’s high-spec with 4G LTE to work with Docomo’s Xi network. Yeah, as with so many other Fujitsu products, this will likely gear up to be a Japan thing.

Going through the rest of the spec sheet, we find a 10.1-inch capacitive multitouch display (not sure how rugged that can be; all other rugged tablets I’ve seen are resistive), the same dual-core TI OMAP 4430 1GHz processor as the BlackBerry PlayBook, 1GB of RAM, 16GB storage, Bluetooth 2.1+EDR, WiFi-b/g/n, GPS, dual cameras (5MP in the back), microUSB, microSD, and microSIM, along with a 1-seg TV tuner.

It’s rugged, so it’s a bit beefier at 599 grams. Fujitsu and Docomo haven’t confirmed it yet, but a formal announcement is expected early next month.
