Shaving systems and methods

1. A shaving system comprising:

a shaver including a shaver head;

one or more sensors configured to detect a flow or sound of water or an orientation of the shaver; and

a processor configured to determine a duration and/or water usage during a shaving session and/or a rinsing session;

wherein the processor includes an algorithm configured to collect data from the one or more sensors and provide accuracy metrics of water usage and provide relevant advice to a user.

2. The system of claim 1 , further comprising a remote device configured to display one or more of the duration and/or the water usage for the shaving session and/or the rinsing session.

3. The system of claim 2 , wherein the one or more sensors includes a microphone on or within the shaver and/or on or within the remote device.

4. The system of claim 1 , wherein the one or more sensors includes an accelerometer on or within the shaver.

5. The system of claim 1 , wherein the one or more sensors includes a stroke sensor on or within the shaver.

6. The system of claim 1 , wherein the one or more sensors includes an orientation sensor on or within the shaver.

7. The system of claim 3 , wherein the processor is configured to determine the duration and/or the water usage of the shaving session by analyzing one or more signals from the microphone.

8. The system of claim 3 , wherein the processor is configured to determine the duration and/or the water usage of the rinsing session by analyzing one or more signals from the microphone and/or one or more signals from an accelerometer and one or more signals from a stroke sensor.

9. The system of claim 3 , wherein the processor is configured to measure a total duration and/or total amount of water used during a plurality of rinsing sessions for the shaver.

10. The system of claim 3 , further comprising an alarm configured to be activated if signals from the microphone are received during a predefined amount of time.

11. A computer-implemented method of analyzing a shaving session, the method comprising:

receiving one or more signals from a microphone that are indicative of water flowing, wherein the microphone is coupled to a shaver, and/or to a dock for the shaver;

analyzing the one or more signals from the microphone to determine an amount of water used for a shaving session;

receiving one or more signals from the microphone, an accelerometer, and/or a stroke sensor that are indicative of water flowing over a portion of a shaver, wherein the accelerometer is coupled to the shaver; and

analyzing the one or more signals from the microphone and the accelerometer and/or the stroke sensor to determine a duration and/or an amount of water used for a rinsing session.

12. The computer-implemented method of claim 11 , further comprising communicating one or more of the duration and/or amount of water used for the shaving session or the duration and/or amount of water used for the rinsing session to a remote device.

13. The computer-implemented method of claim 11 , further comprising predefining an amount of time in which signals from the microphone and/or accelerometer and/or stroke sensor are received before activating an alarm.

14. The computer-implemented method of claim 11 , further comprising determining a value or index of water consumption of a shaving session based on the signals from the microphone and/or the accelerometer and/or the stroke sensor.

15. The computer-implemented method of claim 11 , further comprising providing personalized shaving advice to a user on shaving razor and/or head choice and/or shaving techniques, in order to improve water consumption.

16. The system of claim 4 , further comprising an alarm configured to be activated if signals from the accelerometer are received during a predefined amount of time.

17. The system of claim 5 , further comprising an alarm configured to be activated if signals from the stroke sensor are received during a predefined amount of time.

18. The system of claim 1 , wherein the algorithm is configured to be trained during use of the system thereby becoming accustomed to user's individual shaving style and needs.

19. The system of claim 1 , wherein the processor include one or more computer logics, the computer logics including one or more artificial neural networks configured to be trained to recognize when water is flowing and/or when the shaver is being rinsed.

20. A shaving system comprising:

a shaver including a shaver head;

one or more sensors configured to detect a flow or sound of water or an orientation of the shaver; and

a processor configured to determine a duration and/or water usage during a shaving session and/or a rinsing session;

wherein the one or more sensors includes a microphone on or within the shaver and/or on or within a remote device.
