A mechanism for improving a reliability of a virtual network and resources used. At a virtual network operator level, a request for providing resources for the virtual network is sent towards an infrastructure provider level. The request includes an indication regarding a required availability and reliability level which is to be achieved by the resources of the virtual network. At an infrastructure provider level the request is processed in order to determine the required availability and reliability level, and it is checked whether the required availability and reliability level is achievable for the resources to be provided for the virtual network. A result (confirmation or denial) of the check is sent back to the virtual network operator level.

An occupant restraint system of a vehicle has an airbag, a pre-crash sensor which calculates a probability of a collision of a vehicle with an object and outputs a pre-crash signal indicating a prediction of the collision when the probability is higher than a predetermined value, a satellite sensor which detects a degree of acceleration of the vehicle and starts outputting an acceleration signal indicating the detected degree of acceleration in response to the pre-crash signal, and an airbag ECU which processes the acceleration signal to obtain a processing result and deploys the airbag when the processing result indicates a collision of the vehicle with the object. Therefore, because the airbag ECU does not start processing the acceleration signal until the satellite sensor outputs the acceleration signal in response to the pre-crash signal, a load on the airbag ECU can be alleviated.

A method for detecting a magnetizing inrush current of a transformer includes the steps of obtaining a difference current for each AC phase of a transformer and calculating, for each AC phase, at least two factors for waveform symmetry recognition, on the basis of the difference currents obtained within one period.
