Abstract: A razor having a handle with a power source. A cartridge has a skin contacting surface mounted to the handle. A metallic heat dissipating strip has an upper skin contact surface adjacent to the skin contacting surface of the cartridge. A heating element is positioned below the heat dissipating strip. The heating element has a resistive member with a pair of electrical contacts and a resistance of about 0.5 Ohms to about 20 Ohms. A ceramic insulating member is positioned between the metal heat dissipating strip and the resistive member. An electrical circuit is in electrical communication with the power source and is configured to deliver energy to the resistive member to heat the resistive member of the heating element. The resistive member of the heating element delivers heat to the heat dissipating strip.

Abstract: A safety razor has a handle and a cartridge selectively detachable from the handle. The cartridge has at least one blade with a sharp cutting edge and an expected shaving utility. A connecting structure is coupled to the handle and attaches or detaches the cartridge from the handle in response to a detachment action performed by a user. A detector within the handle has an actuator coupled to the connecting structure and a sensor for generating a signal, wherein the actuator applies an action on the sensor during the action and the sensor generates the signal in response to the action.

Abstract: A powered wet razor has a handle and a cartridge selectively detachable from the handle. The cartridge has at least one blade with a sharp cutting edge and is characterized by an expected shaving utility. An electrical arrangement that detects and tracks utility of the razor and determines a remaining shaving utility based on the expected utility and the tracked utility. The razor includes an indicator for providing a remaining shaving utility signal to a user.

Abstract: A safety razor has a blade unit having at least one blade with a sharp cutting edge. A dielectric handle is configured to carry the blade unit and a conductive ground member is disposed within the handle. The safety razor has an electrically operated device. An electrical arrangement having a sensor electrically coupled to the blade unit and the ground member senses skin contact with the blade unit and actuates the device based on the sensing.

Abstract: Razors are provided that include an electrical circuit configured to deliver energy to a heating element positioned within the razor cartridge. The heating element heats a heat dissipating strip positioned in the razor cartridge which dissipates the heat to the user's skin during shaving.
