(speaker notes duration: 10 minutes)
The Oral –B Braun 5000 electric toothbrush has a number of accessories that enhance its usage such as
the smart guide and the smartphone Oral-B App. The toothbrush is designed to help in save time while
cleaning teeth and to ensure that the teeth become very clean. The Smart Series 5000 electric toothbrush
can be used with an interactive wireless display also known as the SmartGuide. Two key components in
the operation of the toothbrush are the timers and the pressure sensors. The toothbrush has a timer which
alerts the user when cleaning their teeth to avoid cleaning some quadrants longer than others. There are
two types of timers namely the professional time and the 2-minute timer. The professional timer is set
based on the user’s preferred brushing mode majorly for deep cleaning mode which allows for 45 seconds
per quadrant. The 2-minutes timer is mainly for the daily clean mode which allows for about 30 seconds
for each quadrant. The Oral-B toothbrush, SmartSeries 5000, is comprised of the brush head,
pressure sensor light, on/off button, brushing mode button, handle, radio transmission display
which incorporates Bluetooth wireless technology, charge level display, basic charger and brush
head compartment with protective cover, SmartGuide, SmartGuide holder, wall mount, adhesive
ring, travel case and charger pouch depending on the model chosen. The toothbrush has a
waterproof handle and is said to be electrically safe and designed for use in a water flowing area
such as the ablutions. The brush head is wet from a tap and some paste is applied on it. The user
can apply the toothpaste that they prefer. It is recommended to guide the toothbrush to the teeth
before powering on the toothbrush to avoid splashing the toothpaste. The user guides the toothbrush
from one tooth to the next and the teeth are cleaned from the outside, to the inside, and later on the
chewing surfaces. The system divides the teeth into 4 quadrants where each is cleaned in about 30
seconds. The user may seek dental advise from a dentist on their most effective brushing technique. The
toothbrush may cause the user’s gums to bleed in the beginning but one gets used to it especially after
learning to set customized modes for personal brushing. The most preferred mode for such situations is
the sensitive mode. The toothbrush connects to the smartphone app using the Bluetooth wireless
technology. It is required that the smartphone should run on Bluetooth 4.0 or higher versions of it. The
pairing starts immediately one powers on the toothbrush. The user keeps the smartphone in close
proximity so as to read the instructions displayed on the app when different brushing modes are chosen.
The app synchronizes the brushing data for later use. It is important to store the phone in a dry place for
better performance. When one is done brushing, the brush handle is powered off and the user rinses the
brush head under running water while the handle is switched on. The toothbrush handle and brush head

are cleaned separately. The SmartGuide comes with the toothbrush as an accessory. The user can
mount it on the washroom area wall using the wall mount accessory. It assists the user interact
with the toothbrush in a more efficient manner. During purchase, the SmartGuide is set to the
demonstration mode which is not effective for the users. The user can reset the toothbrush from
this state to their brush mode of choice using the reset button in the battery compartment. The
user can now set the timer as they prefer based on their dental hygiene plan. It allows for
response to events on different accounts. When the charger unit is plugged in to a power outlet,
the toothbrush begins charging. A blue light indicator turns on to show that the toothbrush is
charging. When a user applies too much pressure when brushing their teeth, the pressure sensor
detects and shows a red indicator light to warn the user to reduce the pressure applied while
brushing. The toothbrush synchronizes with the Oral-B App that runs on the smartphone, either
android based or iOS based. The SmartGuide is assigned to its own toothbrush handle in cases
where more than one person is using the toothbrush in the home. This is important to avoid
interference and a mix up of messages from the toothbrush handle. The state chart is a type of the
unified modelling language in software development that focusses on designing the system
behavior. It uses states and events to demonstrate the interaction. The software is used to draw
the state diagram of both electric brush and Smart guide. The features and functionalities are
easy to grasp before using the toothbrush as indicated on the manual. In the brush set, the first
thing you do is you set up the toothbrush. The head of the brush should be wet and then an
individual’s favourite tooth paste can be used to clean the tooth. The entrance of the power is a
zero. When you set up the brush, you can now connect the brush handle to the bristles and power
it on. Powering it on will change the state to one and show an indicator of the green light. One
can brush the teeth. The brush head is used to clean the teeth before enabling the electrical
section to avoid splashing out the paste. In the Brush mode, one begins the brushing process
from the outside to the inside and finally the end is to clean on the chewing surfaces of the
mouth. Load the sensitive mode on the smart guide of the toothbrush in the early stages of using
the toothbrush to avoid getting the tooth gums damaged or bleeding. One can consult a physician
when the bleeding is continuous while loading the sensitive mode. Brushing the teeth is
recommended to brush the teeth for 30 seconds per quadrant. If the brush detects that a lot of
pressure is being applied by the user, the brush will send a pressure warning or a pressure alert
which will take the brush to idle state. After 2 seconds the brush will check if the pressure has

recommended to brush the teeth for 30 seconds per quadrant. If the brush detects that a lot of
pressure is being applied by the user, the brush will send a pressure warning or a pressure alert
which will take the brush to idle state. After 2 seconds the brush will check if the pressure has

been reduced; if the pressure has been reduced it will check the pressure level and either proceed
to brushing again else it will go back to idle state. After all the quadrants are fully brush, you
now power off the brush. Similarly, we have the smart screen. The smart screen has few steps. The
smart screen runs on a smart phone app. You power on, after 20 seconds, the screen displays the
instructions on how to use the brush. After about 150 seconds it synchronizes data from the tooth brush.
While enabling tongue cleaning mode, it is recommended to use the sensitive head of the electric tooth
brush. As it is a sensitive cleaning mode, the tooth paste is not required. One can brush without the tooth
paste. Gently provide slow motion while cleaning the tongue. Repeat this motion for the whole tongue. 20
seconds of gentle motion on the tongue is enough for brushing. The Smart Guide helps to intimate the
completion of 20 seconds brushing, using a smiley face. The timer is set for the professional timer
mode and the 2-minutes timer mode. In 2-minute timer, when two minutes completes, the device
signals green color light with a short shuttering sound. In professional timer, the green color with
short shuttering sound is played for every 30 seconds. This timing will vary with 40 seconds
when it moves into the next quadrant. Generally, deep clean mode is recommended. Resetting
the timing for each time is not necessary because, it automatically resets even if the device is
either switched off or paused. To change the timer mode to ‘two minutes’, the mode button
should be long pressed for 3 seconds. After showing 30 seconds on Smart Guide, the button should be
pressed. Then, in the timer on/off button should be pressed, to set 2-minutes timer. When excessive
pressure is given on the tooth, the green light changes to red light. Then, the cleaning mode will
automatically change from daily clean or deep clean mode to sensitive mode. This process is checked
periodically when giving a small press on the toothbrush, while brushing. After completing
brushing and finding the pressure sensor it will be automatically turned off and enables the
tongue cleaning mode.
In a nutshell, state charts are used in the analysis state of system modelling and in the design.
The state charts are useful in describing the system behavior of business systems as well as
product systems. The exercise seeks to develop state chart diagrams for the system or product
and ensure the coordination of all the entities. The state charts design the behavior of the system,
they can be very complex with nested states within other states as well as the use of the multiple
parallel concurrent states. The state charts are useful to help design an object’s method logic.
