Simple enough, really. It's a purse with a small GPS device and display screen hidden discreetly inside the main pocket. Just open it up a bit and peer inside, and always know where you are. Powered by a Faraday-type kinetic system, and with a small Li-ion battery to maintain power even when you're
seated at your desk all day.
Bonus: If ever it's snatched, just call the manufacturer and there's a possibility they can track the purse's location.

Sacagawea was an Indian guide for Lewis and Clark's expedition across the Louisiana Territory in 1803-05. |

How can they track the purse's location? |
|
| |
Most current GPS chipsets don't work indoors. |
|
| |
Either by finding the most-recent contact, which seems rather Orwellian, or by using one of the newer GPS systems which do work in some indoor environs. |

That's really not the primary focus, just something that hit me as I was typing up the rest of the idea. |
|

I don't get it, it's a GPS device, in a purse, right? Would putting a GPS device in your pocket be a similar idea to this? |
|
| |
In recent days there have been a few references here that I read as implying that the location of every GPS receiver can be determined by the satellite network. |
|
| |
Would there not have to be two devices: the receiver to decipher the coordinates based on the satellite signals and a transmitter to relay those coordinates to whatever monitoring network is in place? I'd be concerned about how long that itty-bitty battery could sustain the transmission. |

The well known "LoJack" stolen vehicle locator system uses power from the car's battery to replenish the charge in its internal battery. Since a LoJack is about the size of a pack of cigarettes, if one were willing to plug in their purse as needed to keep the battery charged, I guess you could LoJack a purse. |

[half] - hence the kinetic power system. Battery power would be consrved when the system is inactivate - perhaps some sort of tilt-toggle to turn on the screen (swing it up, hit the connectors). Modern GPS systems can run up to a day on 2 AA batteries - which is similar to many flashlights. As for the number of components required, I'll presume you're referring to the snatched-purse addendum, which again is more of a hidden bonus than a planned use, but I'll clarify that just to be sure. |

[zen_tom] - The point of this is that it's a bit more hidden, and it's always with you. This way, someone in an unfamiliar environment, or who just wants to know how much farther something is, can simply take a peek in her purse - just like looking for chap stick. |
