Abstract: A mixing arrangement for mixing two solutions, a mixer settler unit and a use. The mixing arrangement includes a mixing device arranged in the mixing space for rotating therein, the mixing device comprising at least two helical bars supported around a shaft and rising upwards from the bottom section of the mixing space. The helical bars are fixed to the shaft with support spokes. The ratio of the diameter (D) of the mixing device to the average diameter (T) of the mixing space, that is D/T, is 0.47 at most.

Abstract: A mobile robot configured for vending consumable items. A system configured for vending consumable items comprising a mobile robot, a vending terminal, and a server communicating with each of the other two. A method for vending consumable items using a mobile robot. A method for on-demand consumable item delivery by a mobile robot.

Abstract: A mobile robot is configured for vending consumable items. The robot includes a mobile base; a body comprising an item space; a plurality of support elements located in the item space and configured to support consumable items; an item sensor configured to detect presence of one or more consumable items supported by each of the support elements; and an insert configured to removably fit into the item space, and wherein the insert comprises the support elements and the item sensor. A method for vending consumable items uses the mobile robot.

Abstract: A signaling device for increasing visibility of a mobile robot. The signaling device comprises (a) a base section, attached with a rotational joint to a side of the mobile robot, said rotational joint allowing the device to rotate clockwise and/or anticlockwise relative to the mobile robot, the rotational joint constructed and adapted to return the device to an equilibrium position; and (b) a body section comprising a mast, the body section flexibly attached to the base section at a lower extreme of the body section.

Abstract: A method for establishing a TCP connection between two client terminals protected by stateful firewalls and comprising means for sending messages to each other via a messaging server. The client terminals agree on establishing a mutual TCP connection by sending a message, which indicates port numbers to be used on said connection. A TCP connection establishment procedure is started in both client terminals. After sending a first handshake message, a message indicating a sequence number of the first handshake message is sent from both client terminals to each other. When the firewalls of the opposite client terminals reject the first handshake message, an acknowledgement message to the first handshake message is created in both client terminals using a raw socket, which acknowledgement message includes the received sequence number as an acknowledgement number. Finally, the raw socket based acknowledgement message is sent to the opposite client terminal for completing the establishment of the TCP connection.

Abstract: In order to reduce the size of a signaling message advertising prefixes, a super block prefix is determined amongst two or more prefixes having a common pattern. Information on the super block prefix and delta information on each non-super-block prefix is used in the messages instead of the prefixes as such, the delta information indicating how the prefix differs from the super block prefix.
