Abstract: A system (100) for managing incoming calls in a user's mobile device (3) while using a user's virtual reality, VR, device (1), comprising a user's mobile device (3) comprising a SIM card associated to a Mobile Subscriber Integrated Services Digital Number, MSISDN, the SIM card associated to a mobile carrier from an IP Multimedia. Subsystem, IMS, network (6), a user's virtual reality, VR, device (1) comprising computing means (2) to perform a pairing process between the mobile device (3) and the user's VR device (1) and managing incoming calls, an authentication module (4) configured to authenticate the user's mobile device (3), wherein authenticate means that the VR user (A) is in possession of the user's mobile device (3) comprising the SIM card; and a Web Real Time Communications Gateway, WebRTC GW(5) connected to the IMS network (6) of the mobile carrier and configured to translate IMS signaling into WebRTC signaling.

Abstract: A sequential or cascading predictive control method is provided, including first solving a cost function and then a second cost function for two or more control objectives. The method includes separating the cost function into at least two or more cost functions, depending on the number of defined control objectives. The method additionally includes controlling a first variable with a unitary cost function, a single term or nature of the control objectives. The method also includes determining the possible states that minimize the cost of the first objective to be controlled. Considering only the options given through this determination, a second variable is controlled with a cost function that minimizes the cost function thereof.

Abstract: A multilevel converter allowing the reduction of volume and accessibility to the control and transformation of electric power, including at least two basic cells and having: a) a first power switch that interconnects a positive bus between the two basic cells connected in cascade each other; b) a second power switch that interconnects a negative bus between two basic cells connected in cascade each other and c) a capacitor with a third power switch, connected in series and interconnected between the positive and negative bus.

Abstract: A multilevel converter operating with fewer components saving costs, losses, size and weight, allowing the reduction of volume and accessibility to the control and transformation of electric power, comprising at least a basic cell formed by: a) a first power switch that interconnects the positive bus between said at least one basic cell and at least another basic cell connected in cascade each other and/or a basic cell and a continuous voltage source; b) a second power switch that interconnects the negative bus between said at least one basic cell and at least another basic cell connected in cascade each other; and/or a basic cell and the continuous voltage source of point a); and c) a capacitor with a third power switch, both of them being connected in series each other and interconnected between the positive and negative bus.
