STATE TRANSITION DIAGRAM
ASSIGNMENT I

INTRODUCTION
The Oral B Braun 5000 Electric toothbrush is a great dental solution that contains a brush head,
pressure sensor light, power buttons, brushing mode button, handle, radio transmission display,
charging unit and charge level display, Smart Guide, wall mount, adhesive ring, travel case,
pouch, and a smart Guide holder. The toothbrush is sold alongside a user manual to guide the
user in operating the toothbrush and the smart guide. The toothbrush is recommended for use by
persons above the age of three. Children and teenagers may use the toothbrush with guidance
from an adult. There are two distinct parts of the electric toothbrush package, namely, the electric
toothbrush, and the wirelessly connected smart guide (see appendix I). The toothbrush guide
warns of slight bleeding at the initial stages of using the toothbrush. The bleeding is bound to
stop after a few uses but if it persists, users are advised to seek dental attention.
The toothbrush comes in a variety of Oral-B Brush heads that fit the Oral-B toothbrush handle
and the oscillating rotating brush heads for the tooth-by-tooth precision cleaning. Oral-B
toothbrush has the CrossAction brush head and the FlossAction brush head.
OBJECTIVES
(I) To familiarize the reader with the toothbrush and SmartGuide by reviewing the User
Manual.
(II) To determine the functionality of the Oral B Braun 5000 electric toothbrush.
(III) To determine the functionality of the Oral B Braun 5000 SmartGuide.
(IV) To determine the state transition diagram of the toothbrush and SmartScreen using
MATLAB software.
FUNCTIONALITY OF THE ORAL B BRAUN 5000 ELECTRIC TOOTHBRUSH
(i) The electric toothbrush is connected to an electric outlet and the toothbrush handle is
placed on the charging unit. For a 2-minutes brush, the toothbrush must be charged
for about 40 minutes. It is impossible to overcharge the toothbrush.
(ii) For brushing purposes, the brush head is wet and the user applies toothpaste of
choice. The brush bristles need to be placed on the teeth before the toothbrush is
turned on. The recommended brushing technique is to guide the brush head slowly
1

from tooth to tooth while spending few seconds on each tooth surface. The brushing
techniques seeks to clean up each of the four quadrants of the mouth with equal time
frames.
(iii) The electric toothbrush has two timer options: professional or the 2-minute timer. The
former timer allows for the deep clean mode of brushing while the 2-minute timer is
the recommended brushing time by dentist. They provide short stuttering sounds and
a green light once activated. The timer has a memory which determines the time that
has lapsed during brushing even if the brushing is paused or stopped. The timer can
be reset and it automatically resets when the toothbrush is paused for 30 seconds. The
user has the option of personalizing the timer to change the brushing mode and setting
time for each quadrant cleaning and pause time.
(iv) The toothbrush is able to detect when a user applies excessive pressure on their teeth
while brushing as there is a pressure sensor in the electric toothbrush setup. The red
light of the pressure sensor is activated when too much pressure is applied. In normal
cleaning pressure mode, the green light is active. The pressure sensor in the electric
toothbrush is turned off during tongue cleaning.
(v) The interaction of the SmartScreen, SmartGuide, and the electric toothbrush allows
the toothbrush to run six different brushing modes alongside personalized modes. The
different brushing modes are the daily clean, deep clean, sensitive mode, whitening
mode, gum care mode, and the tongue cleaning mode.
FUNCTIONALITY OF THE ORAL B BRAUN 5000 SMARTGUIDE
(i) The SmartGuide connects to the Oral-B Braun 5000 Toothbrush using radio
transmission, notably, Bluetooth. For first time users, there is a demonstration mode.
The SmartGuide allows for the adjustment of the clock time.
(ii) The Guide displaying a blank screen indicates a need to replace the batteries before
inserting them into the SmartGuide for use. There is a set of batteries provided during
the purchase of the toothbrush. If the batteries have run out, one can purchase more
from the stores.
