Cell Phones New Silent Alert System By Shocking Owner

Motorola has recently received a patent for a completely silent way of alerting users to incoming calls and messages, the patent involves alerting the owner using mild electric shock.

The system, uses a small pad containing electrodes that are wirelessly linked to a handset, when an event occurs on the handset, an electric potential is placed across the electrodes, stimulating the skin and underling muscles, thus alerting the wearer.

Motorola claim that the device is designed to address the problem that a vibrating alert is not truly silent - especially if the handset is placed on or next to a hard surface, such as a table or keys in a pocket. The new system solves this by having no moving parts, thus creating no noise.

Power levels and frequencies can be adjusted, allowing the owner to give a sort of 'personal ring' to an individual caller. The system is not expected to be included with handset for some time.
