  • Patent number: 10440021
    Abstract: A first controller generates a first group key, executes first mutual authentication with devices within a group, and shares a first group key with devices that have succeeded in authentication. At least one controller within the group decides a coordinator that manages a group key used in common in the group, from controllers including a second controller newly joined in the group. The first controller executes second mutual authentication with the coordinator, and shares the first group key with the coordinator. The coordinator performs encrypted communication within the group using the first group key. The coordinator generates a second group key when valid time of the first group key is equal to or smaller than a predetermined value, executes third mutual authentication with the devices and controllers within the group, and updates the group key of the devices and controllers that have succeeded in authentication to the second group key.

  • Patent number: 10404453
    Abstract: At least one controller in a group selects a coordinator that manages a group key to be used in common in the group from among controllers in the group in accordance with an attribute of the controllers. The selected coordinator generates a group key, performs mutual authentication with devices and the controllers in the group, and shares the generated group key with devices and controllers that have been successfully authenticated. The coordinator then generates encrypted data and authentication data by using the group key and simultaneously broadcasts a message including the encrypted data and the authentication data.

  • Publication number: 20190212136
    Abstract: Provided are an evaluation method for objectively evaluating the glow of the skin, a skin glow improver, and a method for examining skin glow improvers. This method for evaluating the glow of the skin comprises assessing the specular reflectance and diffuse reflectance of skin after polarized light is applied to the surface of the skin, and determining that glow is present in the skin when prescribed conditions are satisfied. A skin glow improver is provided by combining an alkali metal salt of alkoxysalicylic acid and trimethylglycine. This method for examining skin glow improvers makes it possible, using a significant decrease in surface roughness as an indicator, to examine samples capable of improving the specular reflectance of the skin.

  • Publication number: 20190126785
    Abstract: Forward tilting of a seat back and pushing of the seat forward allow fixation between an upper slide and an upper slide rail to be released, thereby allowing the upper slide to reach a tip end position of the upper slide rail. With this structure, a lower lock mechanism releases fixation of a lower slide to a lower slide rail and a vertical slide lock mechanism fixes the upper slide and the lower slide. Further, pushing the seat back toward a seat front side allows the lower slide integrally provided with the upper slide to move to a tip end position of the lower slide rail.

    Abstract: According to various aspects, a flow system for transporting microparticulate samples in a hydrodynamically planar flow in a selected flow direction includes a flow chamber extending in the flow direction, having first and second apertures on opposed surfaces of the flow chamber. A sheath-fluid channel has first and second branches to carry the sheath fluid into the flow chamber through the first aperture and having orientations separated by less than about 15° at the first aperture; and third and fourth branches to carry the sheath fluid through the second aperture and having orientations separated by less than about 15° at the second aperture. In some examples, guide channels extend from the apertures substantially perpendicular to the flow chamber at the apertures, and sheath-fluid channel supply sheath fluid to the guide channels.
