Abstract

A shaving implement includes a blade assembly configured for a wet shaving process wherein a user of the shaving implement grips a handle and draws the blade assembly across a surface of skin to be shaved. The shaving implement also includes an energy-imparting device, circuitry, and an activation device. The energy-imparting device is configured to impart energy to enhance the wet shaving process. The activation device is configured to impart a signal to the circuitry in response to handling of the having implement during the wet shaving process. In response to receiving the signal, the circuitry either extends or initiates an application of signals to the energy-imparting device that enable the energy-imparting device to impart energy that enhances the wet having process.

Claims

1. A method of shaving comprising:

providing a blade assembly pivotally coupled to a handle portion, the blade assembly pivoting with respect to the handle portion, the blade assembly including a plurality of blades, the handle portion including an activation device and containing an energy imparting device and circuitry, the circuitry including a controller having a memory device, the memory device storing information indicative of one or more of an operating power level and a time duration;

receiving an activation signal at the controller from the activation device; and

in response to receiving the activation signal, applying, with the controller, power signals to the energy imparting device according to one of the power level and the time duration while a user manipulates the handle portion to pull the blade assembly across a skin surface in which a primary cutting motion of the blade assembly is derived by the user pulling the blade assembly while the energy imparting device imparts energy to the blade assembly in response to receiving the power signals.

2. The method of claim 1 wherein the applying comprises:

beginning applying, with the controller, the power signals to the energy imparting device upon receiving the activation signal; and

halting, with the controller, applying the power signals when the time duration has elapsed after receiving the activation signal.

3. The method of claim 2 comprising:

controlling, with the controller, the power level of the power signals according to the information indicative of the operating power level.

4. The method of claim 1 comprising:

controlling, with the controller, the power level of the power signals according to the information indicative of the operating power level.

5. The method of claim 4 wherein the power level of the power signals applied to the energy imparting device is based upon pulse width modulation.

6. The method of claim 1 wherein the energy imparting device is configured to impart one or more of vibrational energy and thermal energy.

7. The method of claim 1 wherein the activation device is a user activated switch.

8. A shaving implement comprising:

a handle portion pivotally coupled to a blade assembly, the blade assembly configured to pivot and to pass directly over a skin surface during a shaving process during which a user pulls the handle portion;

the blade assembly including a plurality of blades disposed to pass directly over skin during the shaving process in which the user pulling the handle portion provides the primary cutting motion of the blade assembly with respect to the skin;

an energy imparting device configured to apply energy to the blade assembly to enhance the shaving process, the energy is one or more of vibrational energy and thermal energy; and

circuitry within the handle portion including a microcontroller configured to read information indicative of one or more of a power level and a time duration, the microcontroller configured to control the circuitry to apply power signals to the energy imparting device that are controlled according to the information.

9. The shaving implement of claim 8 wherein the microcontroller is configured to automatically halt the application of power signals when the power signals have been applied for the time duration.

10. The shaving implement of claim 9 wherein the microcontroller is configured to control an intensity of the power signals according to the information indicative of the power level.

11. The shaving implement of claim 8 wherein the microcontroller is configured to control an intensity of the power signals according to the information indicative of the power level.

12. The shaving implement of claim 11 wherein the intensity of the power signals is controlled based upon pulse width modulation.

13. The shaving implement of claim 8 comprising:

an activation device configured to send a signal to the circuitry, the circuitry configured to apply the power signals in response to receiving the signal.

14. The shaving implement of claim 13 wherein the activation device is a user activated switch.

15. A shaving implement comprising:

a handle portion pivotally coupled to a blade assembly, the blade assembly configured to pivot and to pass directly over a skin surface during a shaving process during which a user pulls the handle portion;

the blade assembly including a plurality of blades disposed to pass directly over skin during the shaving process in which the user pulling the handle portion provides the primary cutting motion of the blade assembly with respect to the skin;

an energy imparting device disposed within the handle portion and configured to apply vibrational energy to the blade assembly through the handle portion to enhance the shaving process without providing the primary cutting motion; and

circuitry within the handle portion and coupled to the energy imparting device and including a microcontroller configured to read information indicative of one or more of a power level and a time duration, the microcontroller configured to control the circuitry to apply the power to the energy imparting device according to the information read.

16. The shaving implement of claim 15 wherein the microcontroller is configured to apply the power to the energy imparting device during the time duration and to halt delivering the power at the end of the time duration.

17. The shaving implement of claim 16 wherein the microcontroller is configured to regulate an intensity of the power level based upon the information read.

18. The shaving implement of claim 15 wherein the microcontroller is configured to regulate an intensity of the power level based upon the information read.

19. The shaving implement of claim 15 comprising:

an activation device configured to impart a signal to the circuitry, the microcontroller configured to initiate the application of vibrational energy in response to receiving the signal.
