Systems that track your gadgets or cell phone are around since a while. Ardi Technology Corporation from Taiwan sent us some information about their gadget trackers and pet trackers that feature actually some nice functionality.
The Ardi Mini Tracker 505 and Mini Tracker 506 actually show with a simple LED arrow in what direction you have to go to find your cell phone. This is quite helpful if you are in a hurry and the hint of the direction to search helps I think quite a bit.
The search detection distance of the Ardi Mini Tracker series is 0m~100m. The three major functions are: search, alarm and sleep (power saving). The Master unit is in a clip shape, and the small slave unit can be attached to mobile phones and other valuable items. The Mini Trackers are decorated with Swarovski crystals.

The Ardi Mini Tracker 401 is designed to keep track of your dog. The slave piece is designed to wear on dog collar, and it is water splash resistant with an silicon cover. Different from other pet tracker products, the Ardi Tracker offers an alarm function: When dog is certain distance away from host, both Master and Slave piece would sound a series beep sound.
As far as I can tell Ardi is looking for distributors or OEMs to bring their line-up of mini gadget and dog trackers to the US market.
