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 shaving 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 shaving process.

Claims

1. A shaving implement comprising:

a blade assembly including at least one blade configured for direct contact with a skin surface without an intervening micro-screen, the blade assembly configured for a wet shaving process in which a primary cutting motion of the blade assembly is derived when the at least one blade is drawn across the skin surface using a handle portion configured to couple to the blade assembly;

an energy-imparting device configured to impart energy;

an activation device configured to impart a signal;

circuitry, within the handle portion, including a controller coupled to an information storage device storing operational information indicative of operating parameters pertaining to power signals, the stored operating parameters define at least one of a magnitude of a power level delivered from the circuitry to the energy-imparting device, a duration during which the circuitry imparts power signals to the energy-imparting device, and a time variation of the power level of power signals transferred from the circuitry to the energy-imparting device, the controller configured to read the operational information from the information storage device in response to receiving the signal from the activation device, and the circuitry configured to transfer the power signals to the energy-imparting device according to the read operational information to cause the energy-imparting device to impart energy to provide at least one of vibrations and heat to enhance the wet shaving process according to the read operational information.

2. The shaving implement of claim 1, wherein the activation device imparts the signal in response to either forces on the shaving implement, displacement of the blade assembly relative to a handle, or acceleration of the shaving implement during the wet shaving process.

3. The shaving implement of claim 1 wherein the activation device is configured to be activated by the user such as by pressing a switch.

4. The shaving implement of claim 1 wherein the activation device is an optical sensor configured to sense a relative motion between the blade assembly and a skin surface and wherein the circuitry is configured to adjust the power signals in response to a signal received from the sensor.

5. The shaving implement according to claim 1 wherein the stored operating parameters define at least a magnitude of a power level delivered from the circuitry to the energy-imparting device.

6. The shaving implement according to claim 1 wherein the stored operating parameters define a duration during which the circuitry imparts power signals to the energy-imparting device.

7. The shaving implement according to claim 1 wherein the stored operating parameters define at least a time variation of the power level of power signals transferred from the circuitry to the energy-imparting device.

8. A shaving implement comprising:

a blade assembly including at least one blade configured for direct contact with a skin surface without an intervening micro-screen, the blade assembly configured for a wet shaving process in which a primary cutting motion of the blade assembly is derived when the at least one blade is drawn across the skin surface using a handle portion configured to couple to the blade assembly;

an energy-imparting device configured to impart energy;

an activation device configured to be activated by the user;

circuitry, within the handle portion, including a controller and an information storage device storing operational information indicative of operating parameters pertaining to power signals, the stored operating parameters define at least one of a magnitude of a power level delivered from the circuitry to the energy-imparting device, a duration during which the circuitry imparts power signals to the energy-imparting device, and a time variation of the power level of power signals transferred from the circuitry to the energy-imparting device, the controller configured to read the operational information from the information storage device including time duration information indicative of a time period, the circuitry configured to transfer the power signals based on the read operational information to activate the energy-imparting device for the time period that begins in response to receiving an activation signal from the activation device and to cease transferring the power signals to the energy-imparting device automatically when the time period has ended to cause the energy-imparting device to impart energy to provide at least one of vibrations and heat to enhance the wet shaving process according to the read operational information.

9. The shaving implement of claim 8 wherein the activation device is configured to generate the activation signal in response to handling the shaving implement during the wet shaving process.

10. The shaving implement of claim 8 wherein the activation device is configured to generate the activation signal in response to a user pressing a switch.
