Abstract
A wrist-worn paging receiver provides an incoming message alarm by contacting the wrist of the user by the use of rotating cam lobes that reside inside the paging receiver and that are separated from actual contact with the user's skin by a thin, flexible membrane. Various alarm modes are provided by controlling the ratio of the period of rotation to period of rest of the cam lobes mounted on a cam shaft that is driven by an electric motor inside the paging receiver.
