Abstract

Current pager electro-mechanical vibrational systems incorporating the normal movement of the user to auto- are generally expensive and are prone to electro- matically wind the vibrator. When the pager is worn in mechanical failure. They also tend to draw excessive the belt position, the lanyard chain is in the retracted current, reducing battery lie. A totally mechanical sys- position. When the pager is removed from the belt and tern would eliminate the above mentioned issues, sup- repositioned to the read position, the chain extends and plying a much improved system. The primary issue with automatically winds the vibrational system. When the a mechanical system is that it must be manually wound, pager is returned to the belt the vibrator is now wound this can be very annoying to the end user. A very sim- and is storing potential energy. This potential energy can ple solution to this dilemma is to allow the lanyard chain then be released, becoming kinetic energy when a page to automatically wind a mechanical vibrator during usage, is received. Thus the user is alerted.
