Abstract

Cordless mouse that doesn't use conventional battery (e.g. 2 AAA batteries) for power; it has built-in power that is generated by kinetic energy from the movement of the mouse during normal usage (or periodic user "shaking" of the mouse)

Cordless Mouse Input Device With Built-in Power Generation Mechanism

This invention incorporates a mechanism to generate and store electricity as a result of the movements of a mouse computer input device during a user's normal usage of the device. Since the mouse device is meant to be moved under normal operation, a process of generating electricity to operate the device is provided when the device is being used. There is little concern that electricity is not generated when the mouse device is not in use by the user. However, having a way, such as the use of a capacitor, to store extra electricity generated from the mouse movement enables users to perform mouse clicking operations with no movement type of tasks, if desired.

    Instead of the common battery compartment in a cordless mouse input device, a kinetic energy device is added to the mouse. The kinetic energy device generates electricity and stores it for use from the movements of the mouse input device under normal usage.

    The invention need not be limited to a particular design of a kinetic energy device. From basic physics a copper coil having a magnet with north and south poles is mounted within the coil. The movement of the mouse is translated to spin the copper coil. This can be done using methods similar to those used in battery-less watches and thus generate electricity. A capacitor can be used to store the extra electricity for later use.
