  • Publication number: 20250114289
    Abstract: A tunable hair dye composition that includes a photochromic dye, a cosmetically acceptable solvent and, optionally, a carrier. When activated with a suitable activating electromagnetic radiation, the photochromic dye molecule changes color, thereby imparting a temporary color change to the composition and hair to which it is applied. When deactivated, the photochromic dye is generally colorless. The color imparted by the photochromic dye can be tuned by adjusting the wavelength and/or fluence of the activating and/or deactivating electromagnetic radiation. Thus, a wide variety of different hair colors can be obtained from a single hair dye composition containing specific combinations of photochromic dyes.

  • Patent number: 12273686
    Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
