Abstract

Pagers having extremely small form factors such as credit card pagers are typically powered by coin shaped batteries which have low capacity and high internal resistance in contrast to the AAA and AA batteries commonly used for other pagers. As a result of the choice of form factor and battery for a credit card pager, room inside the pager does not exist for a vibrator, and furthermore, the battery inside the pager could not adequately drive a vibra- tor. There are customers who would, at times, still like to be able to use a vibrator accessory for their credit card pagers. The problem, then, is how to provide a vibrator function for credit card or other pagers having insufticient internal space and insuf- ficient internal battery capacity.

CREDIT CARD PAGER ACCESSORY

  Pagers having extremely small form factors such as credit card pagers are typically powered by coin shaped batteries which have low capacity and high internal resistance in contrast to the AAA and AA batteries commonly used for other pagers. As a result of the choice of form factor and battery for a credit card pager, room inside the pager does not exist for a vibrator, and furthermore, the battery inside the pager could not adequately drive a vibra- tor. There are customers who would, at times, still like to be able to use a vibrator accessory for their credit card pagers. The problem, then, is how to provide a vibrator function for credit card or other pagers having insufticient internal space and insuf- ficient internal battery capacity.

  A solution, especially attractive for credit card pagers as shown in Fig. 1, is to provide an accesso- ry having a unitary housing which, after removing the internal battery and carrier, plugs into the inter- nal battery cavity. A first portion of the unitary

accessory housing replaces the internal battery and carrier with a vibrator device having a form factor compatible with the internal battery. A second por- tion of the unitary accessory housing holds an exter- nal battery which has sufficient capacity to drive the vibrator and the pager. The unitary accessory hous- ing has a locking mechanism to rigidly hold...
