codes coincide, the pager alerts its user of the receipt of a message by outputting a
sound or vibration in a pattern stored in the pager. If different sound or vibration
patterns are stored in the pager, the base station adds a code designating one of the
patterns to the paging signal, and the pager selects and outputs the corresponding
pattern.
Because the fixed sound and vibration patterns must be stored in the pager, the
number of such patterns is limited by the storage capacity of the pager. Accordingly,
protests the appellant, conventional pagers requiring a large storage capacity and
having a limited choice of user alerts. (Spec. at 2).
In contrast, the message portion of the appellant’s paging signal includes
musical data. Based on melody start and end symbols therein, his radio pager
separates the message portion into textual data and the musical data. It then
generates melody frequencies corresponding to the musical data, modulates the
melody frequencies to output a melody, and drives a speaker therewith. With this
configuration, asserts the appellant, the pager can output alert tones in a variety of
patterns. (Id. at 13-14.) He adds that the pager does not require a memory to store
different patterns of alert tones. (Id. at 14.)
