Analysis of Oral-B Braun 5000 Toothbrush and SmartGuide System

This report provides a comprehensive analysis of the Oral-B Braun 5000 electric toothbrush and its accompanying SmartGuide. It begins with an introduction outlining the purpose of the report: to determine the functionality of both devices and improve the state transition of the system. The report details the components of the toothbrush, including the brush head, pressure sensor, on/off button, and charging unit, and the SmartGuide, including its wireless display and mounting options. The objectives are clearly stated: to determine the operation of the toothbrush and SmartGuide and to develop a state transition diagram. The report then delves into the specifics of the toothbrush's operation, including charging procedures, battery status indication, brushing modes, and the use of the SmartScreen. It also describes the functionalities of the SmartGuide, including its synchronization process with the toothbrush and the smartphone app. Finally, the report presents a state transition diagram developed using UML software to illustrate the changing states of the toothbrush and SmartGuide. The conclusion highlights the importance of quality measures and the proper disposal of batteries.

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.
OBJECTIVES
(i) To determine the operation of the Oral B Braun 5000 electric
toothbrush.
(ii) To determine the operation of the SmartGuide and SmartScreen.
(iii) To develop state transition diagram for the operation of the
toothbrush and SmartGuide.

ORAL-B BRAUN ELECTRICAL 500 TOOTHBRUSH
(i) The electric toothbrush is charged using the charging unit which
enables the system to obtain the required power levels before being
used.
(ii) The rechargeable battery on the low shows a blue light that flashes
on the charge level display on the SmartScreen. There is a 40-
minute charge for a 2-minute brushing
(iii) The toothbrush has a SmartScreen that demonstrates the battery
status, brush mode, pressure sensor level, and timer for the
brushing process.
(iv) The brush heads allows for two modes for the flossing and cross
action modes. The two modes ensure the teeth are cleaned on the
outer sections as well as the sections between the teeth. The brush
heads are delivered with substitute in case the brush heads get
damaged.
(v) The toothbrush divides the time spent in brushing the teeth into 45
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.
(vi) The toothbrush can be turned on and the different SmartScreen
modes are changed accordingly using the arrow button to
determine the different modes. The brushing mode is memorized

even when the handle is briefly switched off during brushing. When
pausing longer than 30 seconds or briefly pressing the mode button
during pause the brushing mode resets to the «Daily Clean» mode.
ORAL-B BRAUN SMARTGUIDE
(i) The SmartGuide and SmartScreen are used to indicate the status of
the Oral-B Braun 5000 Electric toothbrush at a given time. The
SmartScreen indicates the battery status, pressure sensor levels,
and the brush mode.
(ii) The SmartGuide instructions are stored in the Smartphone App
before using the toothbrush. To do so, push the «h/min» button in
the battery compartment for at least 3 seconds. The SmartGuide
shows «L---». Turn on your handle to start the synchronization
process. It is finished when «L-1-» is displayed. Turn off the handle.
To assign a second handle to the same SmartGuide turn on the
other handle until «L-2-» is displayed.

(iii) After having synchronized the second handle, «Full» will be
displayed. Exit the synchronization mode by pressing the «h/min» or
«set» button, otherwise it will end automatically after 30 seconds.
STATE TRANSITION DIAGRAM
The system develops a state chart diagram for the Oral B Braun 5000
Electric toothbrush. The state transition diagram seeks to show how the
status of a toothbrush and SmartGuide changes from one state to another
once an action is taken. The software chosen to develop the state transition
diagram for this assignment is the UML diagram software. There are other
alternative software such as Matlab and UML software which perform a
similar task.

CONCLUSION
The quality measures are considered in the implementation of the system.
The electronic handling of batteries is considered alongside the guidelines
for proper disposal.
