The invention discloses a method and a device for identifying unlocking by contact surface type, which solves the technical defects of large occupied interface of operation, inconvenient operation and poor privacy when the active state of equipment is converted by an operation touch screen in the prior art. In the invention, the predefined contact surface shape corresponds to a user interface state of equipment; when the equipment detects that the contact surface shape generated on the touch screen by users is identical to or similar with the predefined contact surface shape, the equipment state is converted to the user interface state corresponding to the predefined contact surface shape. The invention can be applied to interface unlocking, application unlocking and the like, occupies small user interface, and has easy operation and good privacy.

The invention provides a method for improving release, on a surface, of a fragrance from an entrapment structure of at least one fragrance oil and at least one entrapment material. The method destabilizes the entrapment structure by providing at least one trigger molecule which preferentially associates with the entrapment material; and / or at least one release agent which at least partially disrupts the entrapment structure.The invention also provides a composition for improving release of a fragrance from a surface. The composition comprises at least one fragrance oil; at least one entrapment material, the at least one fragrance oil and the at least one entrapment material being capable, in use, of forming an entrapment structure on the surface. The composition also comprises at least one destabilizing material, which permits formation of the entrapment structure on the surface but which destabilizing material can, in use, destabilize the entrapment structure by providing at least one trigger molecule which preferentially associates with the entrapment material; and / or at least one release agent which partially disrupts the entrapment structure; and at least one compatible solvent which doesn't interfere with the formation of the entrapment structure on the surface.The present methods and compositions can improve fragrance perception, by overcoming the differences in fragrance perception that result from different surface, for example, skin, hydration levels and / or different surface types.

An optical waveguide structure capable of optically coupling a surface type optical device, such as a surface emitting laser diode or a photodiode, and a transmission medium, such as an optical fiber, located so that their light output surface and light input surface will form an angle of about 90° with each other simply and easily. The optical waveguide structure comprises a first clad section having a curved surface for gradually turning the direction in which light travels almost squarely and a groove formed in the curved surface along the direction in which light travels, a core section which is made from a transparent material with a refractive index higher than the refractive index of the first clad section and with which the groove is filled in, and a second clad section which covers an exposed surface of the core section and the curved surface of the first clad section and which is integrated with the first clad section.
