Abstract
A hair cutting apparatus comprising a structure (126), a portion (1216) of which being adapted for placement against a skin surface where hair is to be cut, a heat generator comprising one or more heat elements (1214) positioned to touch said hair and heated to a temperature sufficient to cut hair, at least one of said heat elements being juxtaposed with said portion and a controller that controls the power source to provide pulsed heating of said one or more heat elements.
Claims59
A hair cutting apparatus comprising:
- a structure, a portion of which being adapted for placement against a skin surface where hair is to be cut;
- a heat generator comprising one or more heat elements positioned to touch said hair and heated to a temperature sufficient to cut hair, at least one of said heat elements being juxtaposed with said portion;
- and
- a controller that controls the power source to provide pulsed heating of said one or more heat elements such that the heat elements do not burn said skin surface.
1 more element
A method of cutting hair comprising:
- pulsing a heat element touching the skin, said heat element being heated to a peak temperature high enough to cause the cutting of hair without burning of skin at said position;
- wherein
- said pulsation allows the heat element to cool between pulses to an extent that it does not burn the skin while still cutting hair.
A hair cutting apparatus comprising:
- a structure, a portion of which being adapted for placement against a skin surface where hair is to be cut;
- a heat generator comprising one or more heat elements positioned to touch said hair and heated to a temperature sufficient to cut hair, at least one of said heat elements being juxtaposed with said portion;
- and
- a controller that controls the power source to provide pulsed heating of said one or more heat elements, the controller further comprising a velocity detector.
