Hello, guys,
Once I was browsing internet and met some information about some gear. It was made particularly for people who worry about their elderly parents, relatives etc. It is very compact and lightweight, but you can find out through internet the exact location of the person who carries it and his physical condition. I remember the name was something like "Safe Angel" or "Guardian Angel" and it is produced by an American company, but cannot find the website of the company. Has anybody come across it?
Regards,

Above is an interesting evolvment. I also just saw an article about a new medical ring that people will wear that sends basic vital signs info back to the console. Combine that with expanded blue tooth technology from the above article and I think you have a great chance to create an excellent tracking device.

I saw this device being used that upon pressing of the button (looked like a watch) alarm company sends in EMS and FD and PD.
