Abstract

The operation of a pager must sometimes be made as simple as possible. Certain users such as volunteer fire department personnel, may go for days or weeks without receiving a page. When the emer- gency page does arrive, the user may be too unfa- miliar with the pager operation to effectively read the emergency message. For this reason, the auto- matic message presentation concept is presented.

When the emer- gency page does arrive, the user may be too unfa- miliar with the pager operation to effectively read the emergency message. For this reason, the auto- matic message presentation concept is presented.

  The pager is equipped with a photo-detector com- ponent integrated within the confines of the pager housing. The pager housing does have a small open- ing which allows transient light to reach the photo- detector. However, once inserted into the pager hous- ing, the photo-detector is blocked entirely from registering any ambient light. When not actively being used, the pager is kept secured in the pager holster, the photo-detector being blocked entirely by the holster. The photo-detector essentially registers absolute darkness, a light reading ofzero.

  When the pager receives a page, it will alert nor- mally (vibrate, chirp, standard or pleasing alerts). Once the user removes the pager from the holster, the photo-detector will register an increased level of

light energy and will presume the pager has been pulled from the holster. The pager will then auto- matically display the first screen of the page mes- sage. Afier approximately 5 seconds, the pager will display any remaining...
