  • Publication number: 20210296945
    Abstract: A communication control device comprises: an antenna; and a control unit that controls wireless communication related to wireless power transfer to a power receiver device through a power transmitter device. The control unit acquires via the antenna a radio wave status of each of a plurality of channels related to the wireless communication. The control unit acquires a power transmission status of the wireless power transfer. The control unit sets, based on the acquired power transmission status, switching conditions for switching the channel according to the radio wave status. The control unit causes the channel to be switched based on the radio wave status and the switching conditions. The control unit causes the wireless communication to continue on the switched channel.

  • Patent number: 9434819
    Abstract: Surfaces of silicone particles are hydrophilized by plasma treatment. The hydrophilized silicone particles are readily dispersible in aqueous materials without a need for dispersants, typically surfactants. In aqueous cosmetic applications externally applied to the skin such as skin care cosmetics, make-up cosmetics, antiperspirant cosmetics, and UV care cosmetics, for example, products free of skin irritation concern can be formulated because formulation is possible without a need for surfactants.

  • Patent number: 5856392
    Abstract: The synthesis and characterization of novel higher order, multi-arm star polymers comprising polyisobutylene arms connected to condensed cyclosiloxane cores are described. The synthesis has been achieved by hydrosilating olefin-capped (e.g., allyl- or isopropenyl-terminated) polyisobutylene with hydrogencyclosiloxanes carrying a plurality of Si--H groups and simultaneously and competitively converting SiH functions, in the presence of moisture, to Si--OH groups to rapidly self-condense or react with SiH groups to form coupled cyclosiloxane cores via core-core coupling. Thus, higher order stars having many more arms than first order stars can be formed.
