Background of the Invention

For the last ten years, cellular phones market has expended significantly. Almost everyone now has his own cellular phone, and often more than one. It is very simple to use the cellular phone, allowing even to small children to utilize it without any problems. In addition, in the last years, have been introduced cellular phones comprising various features, such as photo and

video cameras, GPS (Global Positioning System) means, etc. These cellular phones are successfully acquired by consumers and have great commercial success in business and private sectors. Many consumers are used to take photographs and to shoot video films by means of their cellular phones rather than by conventional photo and video cameras. In addition, navigation by means of GPS via cellular phones is becoming more and more popular in the everyday life. Various sport and amateur water activities require navigating above and under the water, taking photographs and/or shooting video-film. However, the prior art fails to utilize cellular phones capabilities for transmitting photographs, video films, voice and text messages under the water, and for navigating under the water by means of the cellular phone.

Like any other electronic device, a cellular phone is sensitive to the water and must be kept away from the water to be protected from damage. Therefore, a number of solutions have been proposed, providing nylon waterproof cases in which cellular phones have to be inserted. However, these cases are not strong enough and their hermetic seals can be easily unsealed, especially when diving to the deep water. In addition, at the deep water the cellular phone buttons are pressed due to the strong pressure, disabling the use of said buttons.

In the last years, several solutions have been proposed for employing photo and video cameras under the water. For example, US 6,819,866 discloses a watertight housing for use underwater with a range of different video cameras. The watertight universal housing has a sealable internal cavity, which is adapted to receive a remotely controllable electronic device, a programmable controller, and an electromagnetic signal transmitter in the housing, which is controlled by the programmable controller. The programmable controller is designed to receive a command to control the remotely controllable electronic device from a command-providing device.

However, US 6,819,866 does not teach how to utilize a cellular phone with a camera and/or GPS means for various water activities, such as taking underwater pictures, shooting underwater video films, communicating and navigating under the water, while enabling a user to easily control said cellular phone. In addition, US 6,819,866 does not teach how to enable said user to use different kinds of cellular phone within the same waterproof housing.

Another patent, US 5,305,030, disclosed a camera case which permits underwater video shooting and which is also useful in video shooting on the ground when a hand grip assembly is detached therefrom. In the event of underwater video shooting, a video camera is placed in a main case body, and grips are attached to the case through a link plate. The grip has the function of a remote commander, transmitting infrared control signals from an LED to a signal receiver within a transparent window on the camera case to operate the camera accordingly. Still another application, US 2002/0003584, presents a digital underwater camera, which is hermetically sealed, being cast into a clear plastic totally without seams, seals or O-rings. According to US 2002/0003584, no penetrating wires are needed to control the camera; digital electrical signals for downloading image information from the camera being converted to infrared optical or, most preferably, radio signals that are communicated through the clear housing to an infrared or radio receiver, which in turn preferably connects to a picture- capturing personal computer with operating software. A further patent, US 6,128,441, discloses a waterproof case for housing a camera therein, provided with an operation part which is disposed on said waterproof case, and a signal transmission circuit which is arranged to transmit a signal output of said operation part to the camera housed in the waterproof case. However all these publications, similarly to US 6,819,866, do not teach how to utilize a cellular phone with a camera and/or GPS means for various water activities, such as taking underwater pictures, shooting underwater

- A - video films, communicating and navigating under the water. In addition, these publications do not teach how to enable said user to unitize different kinds of cellular phone within the same waterproof housing.

It is an object of the present invention to provide a method and system for enabling a user, when being under or above water, to take photographs and/or to shoot underwater video films by means of his cellular phone, overcoming all prior art drawbacks.

It is another object of the present invention to provide a method and system for enabling a user to navigate under or above water by means of his cellular phone having GPS means.

It is another object of the present invention to provide a method and system for enabling a user, when being under or above water, to communicate with another person by sending and receiving text and/or voice messages, photographs and/or video films.

It is still another object of the present invention to enable a user to utilize different types of cellular phones within the same waterproof case.

It is still another object of the present invention to provide a method and system, which is reliable, efficient and ensures that no water penetrates inside the waterproof case, even when diving to the deep water.

It is a further object of the present invention to provide a method and system, which is relatively inexpensive.

It is still a further object of the present invention to provide a method and system, which is user friendly.

Other objects and advantages of the invention will become apparent as the description proceeds.
