STATE TRANSITION DIAGRAM
OVERVIEW
The state transition diagram, tests, and the state transition matrix demonstrate these
activities clearly (Biermann & Krishnaswamy, 2006, p. 148).. In some instances, the state charts
are very complex as there are nested states within the actual state as well as multiple parallel
concurrent states (Satzinger, akson, & Burd, 2004). The case study here is the Oral-B Braun
5000 electric toothbrush which operates to enable brushing and flossing. It has a power
component and connects to a Smartphone application when powered on. The state transition
diagram draws information from the smart guide provided by the Oral-B Braun manual. The
processes surrounding the connection to the Android based or iOS app on the smartphone. It has
a SmartScreen which allows the toothbrush to connect to the phone App. The smartphone App
can run on iOS or Android Operating Systems. The App guides one through the entire Bluetooth
pairing procedure. The radio connectivity is limited to Bluetooth wireless technology. The
toothbrush is operated by turning it ON at the power mode selection point. The moment the
toothbrush is turned ON it connects to the application on the Smartphone and starts sharing
information (Oral-B, 2017). Some of the specifications of the Oral-B toothbrush are:

FUNCTIONALITY OF THE ORAL B BRAUN 5000 ELECTRIC TOOTHBRUSH
 Your toothbrush has a waterproof handle, is electrically safe and designed for use in
the bathroom. Plug the charger into an electrical outlet and place the toothbrush
handle on the charging unit. The flashing blue lights indicate that the toothbrush is
charging; once it is fully charged, the lights turn off. A full charge can take up to 24
hours and enables up to ten days of regular brushing (twice a day, for about 2
minutes). After deep discharge, the blue lights might not flash immediately; it can
take up to 10–15 minutes.
 If the rechargeable battery is low a blue light is flashing on the charge level display
for some seconds when turning your toothbrush on/off. If the rechargeable battery is
empty the motor will stop and an orange light is flashing on the charge level display;
it will need a 40-minute charge before you can use it for a 2-minute brushing.
 For everyday use, the toothbrush handle can be stored on the charging unit to
maintain it at full power. Overcharging is impossible. To maintain the maximum
capacity of the rechargeable battery, unplug the charging unit and fully discharge the
handle with regular use at least every 6 months.
FUNCTIONALITY OF THE ORAL B BRAUN 5000 SMARTGUIDE
 It is recommended that the user deactivates the radio transmission after turning off the
toothbrush. Turning off the Toothbrush is done by pressing the on/off button for a
period of 3 seconds. A user guide on the operation of the toothbrush is available on
the smartphone app available from either on Android or iOS play store.
 After brushing, it is recommended that the user brushes the head under running water
with the handle switched on. The device is switched off and the brush head is
removed. The handle and the brush head are cleaned separately.
 The smart guide comes with a demonstration mode. The mode is deactivated by
removing the compartment cover in the back and pushing the time setting button. A
flashing timer indicates that one can now adjust the time.
 The smart guide sets the toothbrush to daily mode depending on the brushing modes
chosen. One can change the brushing mode to any other as listed in the brushing
mode figure below.
