15. 1stSCENARIO

16. KITCHENSCALE
The user uses the scale as a traditional one.
Example:
the user is making a cake and uses the scale only for weigh the different ingredients

take the scale
place the product on scale mode

18. kitchenscale
place a bowl and set tare

19. weigh the ingredient

20. 2ndSCENARIO

21. EXPIRINGTIMER
The user uses the product to set an expiring timer.
Example:
the user bought fresh chicken meat.

22. expiringtimer
take the scale
place the product on timer mode

23. expiringtimer
push the point icon on the ring turn the ring to set the timer

24. expiringtimer
the display will confirm the set of time

25. expiringtimer
press the vocal recognition icon and keep pressing

26. expiringtimer
spell product’s name
release the icon and visualize the name
Chicken

27. expiringtimer
if the name is wrong press cancel

28. expiringtimer
and record again pressing the vocal recognition icon

29. Expiring time started

38. HOWDOESITWORK?

39. SCALE
The piezoelectric trasducer will be compressed between the weight platform
and the internal support plane.

The internal mechanism is composed by a
motor for each ring that moves the gear
and so the ring.
They are fixed on the internal support plane
and they are connected to the driver.

45. ELECTROCHROMICINK
Electrochromic inks will be insert in the ring material in order to create a different
feedback based on color changes.
Green
the ring is set and the registred food is still fresh
Orange
the registred food is going to expire in one day
Red
the registred food expire on the same day

It will be kept active as long as
the ring stays on the
second contact.
