  • Publication number: 20240090733
    Abstract: A method of operating a mobile cleaning robot can include navigating the mobile cleaning robot within an environment. Whether a movement condition is satisfied can be determined and a mopping pad tray can be moved relative to a body of the mobile cleaning robot between a cleaning position and a stored position in response to receipt of a command to move the mopping pad tray when the movement condition is satisfied.

  • Patent number: 10581803
    Abstract: Virtual private network (VPN)-related techniques are described. The techniques provide intuitive mechanisms by which a client device more efficiently establishes a VPN connection. In one example, a client device includes a memory, processor(s), and a VPN handler. The VPN handler is configured to monitor actions initiated by one or more applications executable by the programmable processor(s), and determine whether each of the initiated actions requires a VPN connection via which to transmit outbound data traffic corresponding to a respective application of the one or more applications. The VPN handler is further configured to, in response to a detection that at least one initiated action requires the VPN connection via which to transmit the outbound data traffic, automatically establish the VPN connection to couple the client device to an enterprise network, and transmit the outbound data traffic corresponding to the respective application, via the VPN connection.

  • Publication number: 20090259736
    Abstract: A method for configuring a server load balancer comprises receiving a user command defining a load balancing group capable of representing a plurality of target host servers within a network, and receiving user commands adding the target host servers to the load balancing group, wherein the user commands include configuration information for the target host servers. Upon receiving the user commands adding the target host servers to the load balancing group, the method includes updating a database of the server load balancer to include configuration information for the target host servers. After updating the database, the method includes receiving user commands assigning a label to a subset of the target host servers without creating a new load balancing group and without re-configuring information relating to the target host servers, wherein the label indicates the subset of the target host servers are capable of servicing a specific type of access request.
