Powered wet-shaving razor
View Patent ↗A razor includes a load and a voltage conversion system coupled to a voltage source and the load for transforming a variable voltage provided by the voltage source into a constant operating voltage for driving a load.
1. A powered wet razor comprising:
a usage indicator configured to provide a usage signal indicative of the use of a cartridge wherein the usage indicator further comprises a timer configured to provide data indicative of a time interval during which a motor is in a selected state;
a cartridge detector configured to provide a reset signal in response to attachment of a cartridge to the razor; and
a counter in communication with the usage indicator, the counter being configured to reset a count in response to a reset signal and to change the count in response to the usage signal.
2. The razor of claim 1 , wherein the usage indicator comprises an actuator switch for providing the counter with data indicative of a change in a state of a motor.
3. The razor of claim 1 , wherein the usage indicator comprises a stroke detector for providing the counter with data indicative of an occurrence of contact between the cartridge and a surface.
4. The razor of claim 1 , wherein the usage indicator comprises:
a stroke detector for providing stroke data indicative of an occurrence of contact between the cartridge and a surface; and
a timer in communication with the stroke detector and with the counter for providing the counter with data indicative of a temporal extent of the contact.
5. A powered wet razor comprising:
a usage indicator configured to provide a usage signal indicative of the use of a cartridge, the usage indicator comprising an actuator switch for providing data indicative of a change in a state of a motor; and
a counter in communication with the usage indicator, the counter being configured to reset a count in response to a reset signal and to change the count in response to the usage signal.
6. The razor of claim 5 , further comprising a cartridge detector configured to provide a reset signal in response to attachment of a cartridge to the razor.
7. The razor of claim 5 , wherein the usage indicator further comprises a time for providing the counter with data indicative of a time interval during which a motor is in a selected state.
8. The razor of claim 5 , wherein the usage indicator comprises a stroke detector for providing the counter with data indicative of an occurrence of contact between the cartridge and a surface.
9. The razor of claim 5 , wherein the usage indicator comprises:
a stroke detector for providing stroke data indicative of an occurrence of contact between the cartridge and a surface; and
a timer in communication with the stroke detector and with the counter for providing the counter with data indicative of a temporal extent of the contact.
