  • Patent number: 11955381
    Abstract: Methods for pre-cleaning substrates having metal and dielectric surfaces are described. A temperature of a pedestal comprising a cooling feature on which a substrate is located is set to less than or equal to 100° C. The substrate is exposed to a plasma treatment to remove chemical residual and/or impurities from features of the substrate including a metal bottom, dielectric sidewalls, and/or a field of dielectric and/or repair surface defects in the dielectric sidewalls and/or the field of the dielectric. The plasma treatment may be an oxygen plasma, for example, a direct oxygen plasma. Processing tools and computer readable media for practicing the method are also described.

  • Publication number: 20240107950
    Abstract: A power-assisted working machine and mower. The mower includes a body including a traveling assembly and a drive motor for driving the traveling assembly; a handle device connected to the body and including an operating member, where the operating member includes a grip for a user to hold; and a connecting rod connected to the body. The mower further includes a motor parameter detection device configured to detect at least one of the rotor position and the working current of the drive motor; an angle detection device configured to detect an angle of inclination of a workplane of the mower relative to a horizontal plane; and a controller configured to estimate thrust applied to the handle device according to the rotor position and/or the working current and the angle of inclination.

  • Publication number: 20240099185
    Abstract: A walk-behind electric device includes a device body, a moving wheel, a moving motor, a power interface, and a control unit. The moving wheel is connected to the device body. The moving motor is configured to drive the moving wheel. The power interface is connected to a power supply so as to supply power to the moving motor. The control unit is configured to identify, according to device parameters of the walk-behind electric device, an auxiliary operation that a user wants to perform on the walk-behind electric device, where the auxiliary operation is at least partially positively correlated to at least one output parameter of the moving motor.

  • Publication number: 20150113168
    Abstract: A network device is connectable wirelessly to an Access Point AP that is connected to a server. The network device comprises a processing module to receive a Dynamic Host Configuration Protocol (DHCP) message from a client device, to insert in a predetermined option of the DHCP message a Media Access Control (MAC) address of the client device, and to send the DHCP message to the AP to be forwarded to the server for allocation of an IP address to the client device based on the MAC address inserted in the predetermined option of the DHCP message.

  • Patent number: 8735561
    Abstract: Five optimized genes of capsid L1 protein from human papillomavirus type 16, 58, 18, 6 and 11, which are modified by using insect's preferred codons and so on. Method for modifying those genes to express more highly in insect cells. Virus-like particle's vaccine compositions comprising HPV L1 proteins or their functional relatives produced by using those modified genes. Those optimized genes of L1 can be used to produce HPV 16 VLP, HPV 58VLP, HPV 18VLP, HPV 6 VLP, HPV 11VLP in insect cells. Yields of virus-like particles derived from those optimized HPV L1 genes are high. Mixed multivalent vaccines comprising above optimized HPV L1 genes can be used to prevent and treat multiple HPV infection and diseases related with it.
