The Umbrella

Since the prehistoric times, people tried to protect their selves from unwanted weather conditions. They used animal skins. This system was then improved by rich people, who connected animal skins to sticks to be carried above them by servants.

It is surprising to know that something as simple as an umbrella can be improved. One of the main disadvantages of umbrellas is that they are very "forget-able". In 1989, The inventor of "Unforgettable Umbrella Method" (US patent 4887543) created a approach for the umbrella to remind its owner of his or her forgetfulness:

"A method and a device to aid in recollecting to retrieve an umbrella left in a building including an eye device on the handle of the umbrella with a identification plastic panel attached with a spring clip through the eye. The identification device is unclipped from the umbrella when the umbrella is left behind upon entrance to the building and is immediately clipped onto a key ring on which automobile or residence door keys are clipped. If the umbrella is forgotten, the next use of the key ring will automatically remind the user that the umbrella has been left behind. After the umbrella has been retrieved, the identification device is unclipped from the key ring and reattached to the eye device on the umbrella for the next use."

Very curious people are provided the illustration of the above invention at the right.
