  • Patent number: 7896816
    Abstract: Skin test device has a film backing. The film backing is made of silicone, and is marked off into divisions by grooves. The divisions each have a different sample containing a suspected allergen. The film backing has a see-through feature and the condition of the skin can visually be checked when the film backing is staying on the skin. The divisions are easily separable from each other. When certain samples cause significant allergic reactions, the divisions corresponding to those samples can be removed immediately.

  • Patent number: 7183455
    Abstract: To provide an adhesive dressing that allows a wearer to determine growth of bacteria, if any, as early as possible when the adhesive dressing is staying on the skin of the wearer for wound healing. The adhesive dressing includes a see-through backing made of a silicone material and four circular keepers provided on one surface of the backing. The keepers are impregnated with chemical compositions that change in color to the extent that the color change is visible to the naked eye when bacteria in a wound grow. The conditions to trigger the color change varies from composition to composition. An adhesive is applied along the periphery of the backing. When bacteria grow in the wound, the change in color of the chemical compositions impregnated in the keepers can be visually checked through the backing. This contributes to prompt and early treatment of infected wounds.

  • Patent number: 6911571
    Abstract: To provide a bandage pad for chemical peels that is designed to be stuck on the skin so that the condition of the skin is visually checked while the bandage pad is staying on the skin. A bandage pad for chemical peels comprises a transparent silicone film backing and a chemical peeling agent spread over the entire surface of one side of the film backing. Grooves are formed in the surface of the film backing in both vertical and horizontal directions to define a matrix of small divisions. The divisions are easily separable from each other. When undesirable reactions are observed on the skin, only the division corresponding to the affected site of the skin can be removed immediately.

  • Patent number: 6502583
    Abstract: New findings such as the highlight theory which determines the impression of a face are utilized for the technology of correcting the photograph of face image and for the makeup technology. The method includes determining a requested face which is requested by the person who wants the photograph to be corrected or wants to be made up, and creating an image of the face corrected or made up by executing image-processings such as contour—combining of the original face image or the face of the person based on the requested face.

  • Patent number: 6419672
    Abstract: A method of attaining depilation by laser beam more effectively by enabling a laser beam the output of which is repressed to an extent of avoiding exertion of an effect on the peripheral tissue to reach a depth in the approximate range of 5-6 mm from the surface of the skin. The method of depilation attains required depilation by pulling out the skin of a subject and compressing the drawn skin thereby transforming part of the skin into a flap and emitting a laser beam to the region of the skin transformed into the flap.

  • Publication number: 20010056228
    Abstract: A diagnosis system includes a terminal T and a server S which are connected to each other through a network B. A user images a given position of user's body by an imaging device C connected to the terminal T and transmits image data obtained by that imaging to the server S through the network. The server S compares the received image data with reference data of the server S and automatically diagnoses the user's health condition, to thereby produce diagnosis data. The diagnosis data is equivalent to a diagnosis result whom a doctor says a patient, to thereby realize an automatic diagnosis.
