INTRODUCTION
The information on the Oral B Braun 5000 electric toothbrush and
SmartGuide is derived from the user manual provided alongside the
purchase of the toothbrush. The information determines the functionality of
both the toothbrush and the SmartGuide. The paper seeks to determine
these functionalities and to improve the state transition of the entire system.
The toothbrush can be used with or without the SmartGuide. There is a
smartphone App that guides the user on how to connect the toothbrush to
the charging unit as well as wirelessly connect to the SmartGuide. Most users
mount the SmartGuide on the bathroom walls using an adhesive ring. More
than one user can connect to the SmartGuide within a given radius as
defined under the Bluetooth radio communication guidelines.
The interactive wireless display may encounter electromagnetic interference
and some compatibility conflicts while a toothbrush seeks a connection.
There are restricted surroundings where the connection may be inhibited
and users are notified using warning signs in these specific areas such as the
aircraft sanitation rooms. It is also important to recommend that the people
with heart problems or a pacemaker to ensure they do not go close to the
SmartGuide. The estimated distance from the SmartGuide is six inches. The
electric toothbrush has brush head, pressure sensor light, on/off button,
brushing mode button, handle, radio transmission display, charge level
display, charging unit, SmartGuide, wall mount, travel case, travel charger
pouch and an adhesive ring for mounting purposes.

seconds per quadrant with a few seconds pause. Some timers will
allow for 30 seconds per quadrant. The brush is able to carry out
the cross action and floss action on all the quadrants. The
illustration below shows how the two modes are activated.
