Abstract: A hair cutting apparatus comprising a structure (1260), 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) heated to a temperature sufficient to cut hair, at least one of said heat elements being juxtaposed with said portion and positioned to touch said skin and a controller that controls said heat generator to prevent heat from being applied continuously in a single area for sufficient time to cause skin damage.

Abstract: A method and apparatus for selective photothermolysis of a target tissue within surrounding tissue. The target and the surrounding tissue are heated to a predetermined temperature of about 60° C. by a pulsed heat source such as a flash lamp which creates a temperature gradient in the air included in a cavity formed between the housing of the apparatus and the surrounding tissue. The surface temperature of the tissue is monitored by a sensor unit. When the tissue surface reaches the predetermined temperature the target tissue is heated to the point of coagulation, preferably by narrow band electromagnetic radiation. The temperature difference between the coagulating target and the surrounding tissue is sufficiently mild that heat diffusing out of the target does not damage the surrounding tissue, even in the case of a relatively large target such as varicose veins.

Abstract: A pH sensitive chewing gum kit is provided. The kit may contain chewing gum incorporating a pH sensitive substance. When chewed, the gum may change it's color in response to the oral fluids or salivary pH level. The chewing gum kit may also contain chewing gum with or without artificial sweeteners and one or more pH sensitive members including at least one pH sensitive substance incorporated in at least one portion thereof. When a pH sensitive member is put in contact with oral fluids or saliva, before, during or after chewing the gum, the color of the pH sensitive substance may change to a color which depends on the oral fluids pH value. This color may indicate whether the gum still needs to be chewed in order to achieve a desired oral fluids pH level.
