Abstract: A technique for protecting a cryptographic key. A user has an identifier and an associated password. The first cryptographic key is designed to decrypt a piece of encrypted data. The user device generates a second cryptographic key by applying a key derivation algorithm to at least the password, then encrypts the first cryptographic key by applying an encryption algorithm parameterized by the second cryptographic key. The user device then provides the encryption of the first cryptographic key to a management device for storage. A response associated with a question is obtained from the user. The user device calculates a result of an application of a function to at least one response associated with a question, then provides a value dependent on the result to a management device for storage. The value then enables the user device to determine the password when it has the response to the corresponding question.

Abstract: A method for transmitting downlink data from a mobile communication network to a mobile terminal. The method includes: transmitting, from a mobile terminal to a first network entity of the mobile communication network, a parameter indicating that the mobile terminal wishes to use signalling messages rather than a data transport channel for transmission of downlink data; and transmitting, from a second network entity of the mobile communication network to the mobile terminal, at least one signalling message in which downlink data received by a third network entity of the mobile communication network have been inserted.

Abstract: A method is provided for managing a plurality of media flows to be reproduced by a calling device prior to the finalization of the establishment of a communication. The method is implemented by the calling device prior to the finalization of the communication. The method includes sending a request for the creation of the communication to at least one called device.

Abstract: A system for managing inventory items within a storage facility includes a control server communicably coupled to a first robotic apparatus and a second robotic apparatus. The storage facility includes a dynamic storage space in which a dynamic storage system is placed beneath the static storage system. The control server maps inventory items to one of the dynamic storage system and the static storage system based on a set of attributes. The control server receives request for fulfillment of an order. Based on the received request, the first robotic apparatus retrieves inventory items stored in the dynamic storage system, and the second robotic apparatus retrieves inventory items stored in the static storage system. The inventory items collected from the dynamic storage system and the static storage system are transported to an order fulfillment and replenishment location to consolidate the retrieved items and fulfill the order.

Abstract: Provided is a locker system that includes a plurality of lockable doors, a security lock mechanism, and a plurality of compartments. Opening of each lockable door is controlled based on a corresponding security parameter. The security lock mechanism controls opening and closing of each lockable door based on the corresponding security parameter. Each compartment is accessible from a front side and a rear side of the locker system. An access to each compartment from the front side is controlled by a corresponding lockable door. Each compartment is open from the rear side. When a robotic apparatus, transporting one or more items associated with a process at a storage facility, aligns with the locker system from the rear side, the one or more items are accessible from the front side based on opening of one or more corresponding lockable doors of one or more compartments of the plurality of compartments.

Abstract: A system for transporting inventory in a storage facility is disclosed. The system includes a control server, a robotic apparatus, and a payload (i.e., a mobile storage unit (MSU)). The robotic apparatus includes a track plate, a top plate superimposing the track plate, and a latch lock mechanism including a plurality of latch locks. The control server communicates instructions to the robotic apparatus for transporting the MSU. Based on the instructions, the robotic apparatus aligns beneath a base plate that is attached to a bottom surface of the MSU and raises the top plate to lift the MSU. When the top plate moves relative to the track plate, the plurality of latch locks engage with the base plate of the MSU based on a degree of alignment between the top plate and the base plate, to secure the MSU with the robotic apparatus.

Abstract: A method for singularizing frames to be transmitted by an object connected to a server via a low-power wireless communication network. The singularization method includes an integration, in a frame to be transmitted identifying the transmitting connected object and including payload data, of at least: a counter that can be incremented as a function of the frame to be transmitted, the counter having a predefined dimension; and a supplementary index that can be modified upon a zeroing of the counter. Thus, two frames originating from one and the same object with the same payload data will be unique because they will include at least one counter and at least one supplementary index that are distinct. The use of the supplementary index makes it possible, without reducing the lifetime of the connected object, to singularize a greater number of frames.
