ever lost a beach umbrella or left somewhere? This happens all the time, and it seems that almost everyone I know lost their lives during an umbrella. It was not so long ago, discussing with a friend. He suggested that we need to invent an umbrella GPS positioning device search. This is possible, of course, I mean we have the technology, but it might not be so valuable that such a device is an umbrella, which he bought for only $ 15.00, for a GPS device or a sensor linked to cost almost that much see . Still, let's talk about this potential scenario where you might come up with something?
First of all, I would like to point out that many umbrellas surface of the ribs, which act as an antenna, so the power of the ingredients might not be all that much juice. Speaking of electricity, what about the small solar cell, the kind, which is a small calculator, it is possible, but the "oh wait, use bad under umbrellas weather, so the sun is not likely to shine. That said, even the little calculator solar it seems to work without actual sunlight, artificial light, such as lamps or lights on the bus, train or metro. Maybe even next to a street lamp.
Yes, that things are charged, but I have a battery also because most people put umbrellas in the closet and it's dark there, so there is no more juice when the battery is gone. the other problem is that the GPS triangulation necessary, you need a minimum of three satellites, but when the umbrella doors, closet and no juice left, you will not be able to contact the satellite. Yeah, but you may have to contact your mobile phone active matrix RFID chip and a pinger device. So in this case what we're doing here, as the sensors?
Well, the active matrix RFID chip, probably about $ 1.45 plus the battery is about the same, plus a few strips of metallic material antenna running along the frame and the ribs of the umbrella – perhaps another $ 2 $ 3. Well, there are only about six bucks to the umbrella, so this probably will not work on the $ 15 umbrella, but an expensive designer umbrella, it would make sense and keep you from losing it. So I hope when an engineer of consumer products then please consider this and think on it.
