Abstract

The position of a vibrator motor in a pager is cm- cial to achieve optimum acceleration forces. The posi- tion of a pager on a user's body is also crucial in deter- mining the position of the vibrator. Current pager designs have removable belt clips and holsters which allow for greater versatility when worn on the body. Since the ori- entation of the pager can be easily changed, the orienta- tion of the vibrator should also be changed so that opti- mum acceleration forces can be transferred to the user's body.

AUTOMATICALLY OPTIMIZED VIBRATOR POSITION

by Bradley A. Murray

  The position of a vibrator motor in a pager is cm- cial to achieve optimum acceleration forces. The posi- tion of a pager on a user's body is also crucial in deter- mining the position of the vibrator. Current pager designs have removable belt clips and holsters which allow for greater versatility when worn on the body. Since the ori- entation of the pager can be easily changed, the orienta- tion of the vibrator should also be changed so that opti- mum acceleration forces can be transferred to the user's body.

Figure 1 is a cut-away front view of a pager containing

the spring force of a spring, such as a coil or leaf spring, mounted about the pivot point 6. The base has a protru- sion 8 which extends outside the pager housing 10 through an opening 12 on the back of the pager hous- ing. When a belt clip 14 is attached to the pager, a guide surface 16 on the belt clip contacts the protrusion 8 and forces the vibrator to change position by 90: Upon removing the belt clip, the spring mounted in the base forces the vibrator back to the original position. A sec- ond embodiment would use a similar guide feature on a pager holster to contact the protrusion and force the vibrator to change positions when the pager is installed a vibrator. The vibrator 2 is mounted on a base 4 which in the holster.
