  • Publication number: 20190251754
    Abstract: A makeup application device utilized by a makeup professional obtains a makeup consultation request from a user of a client device and obtains at least one digital image of a facial region of the user from the client device. A three-dimensional (3D) facial model is generated based on the at least one digital image, and user input is obtained from the makeup professional for applying virtual cosmetic effects to the 3D facial model. The makeup application device generates a command based on the user input from the makeup professional for applying a virtual cosmetic effect and transmits the command to the client device. The command causes a virtual cosmetic effect to be applied to the at least one digital image of the facial region of the user and displaying the at least one digital image.

  • Patent number: 10375029
    Abstract: A multimedia broadcasting system having a multiple-node structure includes nodes. Each node is coupled to at least one of the nodes, and the nodes include server nodes and multimedia-playing terminal nodes. Each server node is coupled to at least one of the server nodes and provides at least one multimedia content. Each multimedia-playing terminal node receives multimedia content transmitted by a server node of the server nodes and plays the multimedia content. A first server node of the server nodes is coupled to a second server node of the server nodes, and the first server node transmits, via the second server node, a first multimedia content to at least one multimedia-playing terminal node controlled by the second server node. Each multimedia-playing terminal node is a multimedia play terminal including at least one display device or audio playing device.

  • Publication number: 20190013557
    Abstract: The present invention provides a crosstalk isolation structure for reducing crosstalk, comprising a conductive line and two grounded resistors. The conductive line comprises a plurality of teeth structures arranged periodically. The two grounded resistors are coupled to two ends of the conductive line, respectively. The plurality of teeth structures are periodically arranged in a subwavelength configuration that a period length of the plurality of teeth structures is smaller than the wavelength of an electromagnetic signal generated by a crosstalk around the conductive line, whereby impingement of electromagnetic wave is isolated by the plurality of teeth structures.

  • Patent number: 10090574
    Abstract: The present invention provides a microstrip isolation structure for reducing crosstalk, comprising a microstrip line and two grounded resistors. The microstrip line comprises a plurality of indentation structures arranged periodically. The two grounded resistors are connected to two ends of the microstrip line, respectively. The plurality of indentation structures are periodically arranged in a subwavelength configuration that a period length of the plurality of indentation structures is far smaller than a wavelength of a transmission signal generated by a crosstalk around the microstrip line, whereby impingement of electromagnetic wave is confined by the plurality of indentation structures.

  • Patent number: 9615446
    Abstract: The present invention discloses a pair of differential microstrip lines with low cross-talk for high-frequency signal transmission. The pair of microstrip lines comprises two microstrip lines. The first microstrip line is used to transmit the first transmission signal. The second microstrip line is parallel to the first microstrip line and used to transmit the second transmission signal. The first transmission signal is the complementary signal of the second transmission signal and has a 180° phase difference from the second transmission signal. Particularly, there are a plurality of slots periodically arranged on the outer sides of the first and the second microstrip lines to form a subwavelength configuration. The subwavelength configuration is to make the periodical arrangement length of these slots shorter than the wavelengths of the first and the second transmission signals. These slots can provide subwavelength confinement for enhancing electromagnetic wave.

  • Patent number: 9140855
    Abstract: A structure of a low frequency surface plasmon polariton waveguide includes multiple unit cell blocks arranged at a sub-wavelength period to line up in a one-dimensional line-up direction to form a hollow metallic block periodic structure. Each unit cell blocs includes a body, a penetration section, and an open slot. The penetration section is formed in the unit cell block by extending in a direction perpendicular to the one-dimensional line-up direction so as to define a channel space in the unit cell block. In a low frequency spoof surface plasmon polariton transmission mode, in case of serving as a structure of an antenna, each unit cell block has an electromagnetic field distribution mostly confined in a channel space of the unit cell block; and in case of serving as a waveguide, the electromagnetic field is mostly distributed between two adjacent unit cell blocks with minority distributed in the channel space.
