  • Publication number: 20240065406
    Abstract: A hair/scalp care method includes a washing step of washing a target head part that is one or both of hair and a scalp of a human body, a drying step of drying the target head part that has been washed in the washing step, and a fine water particle application step of applying fine water particles having a size of 50 nanometers or less to the target head part. By applying the fine water particles to the target head part, damage to the target head part can be reduced or the damaged target head part can be repaired. Further, when an agent is used, an effect brought by the agent can be enhanced by applying the fine water particles to the target head part.

  • Publication number: 20230130070
    Abstract: The fine water discharging element capable of transitioning between an adsorption state where water contained in a fluid to be treated is adsorbed and a discharge state where the adsorbed water is discharged to the fluid to be treated, the fine water discharging element comprising a base material portion, a plurality of particles and a nanochannel formed between the shell portions by laminating the plurality of particles on an outer surface of the base material portion in a rich viscoelasticity film shape. The fine water discharging element is transitioned between the adsorption state and the discharged state by changing the temperature of the water in the nanochannel by controlling an electrifying of at least one of the base material portion and the plurality of particles.

  • Patent number: 9924104
    Abstract: This invention provides a technology that allows the acquisition of background differentials using images acquired by a camera, the viewpoint of which moves. First, said camera acquires a background image, i.e. an image that does not contain a target object. Using information on the line-of-sight direction and viewpoint position of the camera, position information for pixels in the background image is transformed to polar-coordinate information Next, the camera acquires an object image. Using information on the line-of-sight direction and viewpoint position of the camera, position information for pixels in the object image is transformed to polar-coordinate information. The polar-coordinate information for the pixels in the object image is used to identify a target background, said target background being the part of the background image in an angle region corresponding to the object image. By comparing the object image and the target background, the differential therebetween is extracted.
