A virtualized network function manager (VNFM) receives a certificate application proxy message sent by a virtualized network function (VNF) instance. The VNFM uses the authentication information to authenticate the VNF instance, and when the authentication succeeds, sends a certificate application message to a certificate authority (CA). Then the VNFM receives a certificate issued by the CA, and sends the certificate to the VNF instance. In this way, through a trusted link between the VNFM and the certificate authority, the instantiated VNF instance applies for a certificate issued by the certificate authority, thereby effectively ensuring security of a management channel between the VNF instance and the VNFM. |

Method and system for idle mode transfer for load balancing across distributed data plane processing entities for mobile core network
A system and an algorithm in a mobile core network to distribute the data load across multiple data processing entities. The system is seen as having one data plane entity to the external entities like routers; hence the system can scale without needing to update the external nodes. In general when a data plane processing entity is added or removed, a new distribution rule is provided to the remaining data plane processing entities. Only after some number of sessions have been migrated does the new distribution get provided to the data distribution entities. This delay allows sufficient sessions to be migrated to minimize the overall number of packets that have to be forwarded for processing. This benefit can be maximized by taking advantage of cellular network's idle mode behavior and by migrating the sessions while they are in idle mode. |

Cloud-based dynamic IOT resource allocation in response to a changing sensor status
A method and associated systems for on-demand Internet of Things bandwidth allocation in response to changing sensor populations. An IOT sensor device adds itself to or deletes itself from a cluster of IOT sensors. A physical IOT controller that manages the cluster detects this change, identifies a resulting change in the cluster's bandwidth requirements, and stores this information in a local database. When such a sensor-population change satisfies a triggering condition, the controller requests that a cloud-based application server adjust the controller's bandwidth allocation. The server aggregates this and similar requests from all connected controllers in a global database, and when controller bandwidth requirements satisfy a second triggering condition, the server, using a standard API, asks the cloud-management platform to reprovision the server's virtual bandwidth allocation. The server then distributes the adjusted bandwidth among its IOT controllers, which in turn allocate their adjusted bandwidths among their sensor devices. |

Switched-mode ripple optimization
Methods and apparatus relate to a minimizing ripple in a polyphase power supply by modulating a voltage pre-regulator output setpoint to minimize ripple performance. In an illustrative example, the modulation may include incrementally adjusting the pre-regulator output setpoint supplied, for example, to a multiphase controller. Some examples may reverse the increment direction in response to determining that the prior incremental adjustment yielded increased ripple. Each phase of the polyphase power supply may include a buck-derived switch-mode power supply connected, for example, to a common output node. Various embodiments may advantageously maximize reduce bulk capacitance requirements for active loads by dynamically seeking a duty cycle of the polyphase power supply with substantially minimal ripple. |

Switched capacitor converter with compensation inductor
Circuits and methods are provided for soft switching within a switched-capacitor DC/DC converter, so as to reduce switching losses and improve efficiency. This is accomplished, in preferred converters, by coupling a compensation inductor between one half-bridge of an output rectifier and another half-bridge of the output rectifier. The compensation inductor functions to transfer charge from or to the capacitance of switches within the converter while the switches are off, such that the voltage across each switch is reduced to zero before that switch is turned on. This provides zero-voltage switching (ZVS) and its associated high efficiency. The efficiency associated with the ZVS makes ideal zero-current switching (ZCS) less important, such that high-precision capacitors and inductors forming the resonant tanks required by near-ideal ZCS are not required. The resultant circuits are physically smaller and less expensive than other converters that require near-ideal ZCS, but achieve similar or better efficiency. |

Q-switched CO2-laser material machining system comprising acousto-optic modulators
A Q-switched CO2 laser material processing system with acousto-optic modulators (AOM) is employed, on the one hand, inside the resonator for Q-switching the CO2 laser and, on the other hand, externally for efficient suppression of the radiation feedback between a laser and workpiece.

Since this frequency shift significantly reduces the amplification of the radiation, it has to be avoided in the Q-switching process, which is achieved, by means of a tandem of two AOMs with identical excitation frequencies but with the acoustic waves propagating in opposite directions in the crystal. The frequency shift advantageously suppresses radiation feedback between the laser and workpiece. |

Low-temperature co-firing of multilayer textured piezoelectric ceramics with inner electrodes
Textured PMN-PZT fabricated by templated grain growth (TGG) method has a piezoelectric coefficient (d) of 3 to 5 times that of its random counterpart. By combining this TGG method with low-temperature co-firing ceramics (LTCC) techniques, co-fired multilayer textured piezoelectric ceramic materials with inner electrodes were produced at a temperature as low as 925° C., which silver could be used. Trilayer PMN-PZT ceramics prepared by this method show a strain increase of 2.5 times, a driving voltage decrease of 3 times, and an equivalent piezoelectric coefficient (d*) improvement of 10 to 15 times that of conventional random ceramic counterparts. Further, a co-fired magnetostrictive/piezoelectric/magnetostrictive laminate structure with silver inner electrode was also synthesized. The integration of textured piezoelectric microstructure with the cost-effective low-temperature co-fired layered structure achieves strong magnetoelectric coupling. These new materials have promising applications including as actuators, ultrasonic transducers, and use in energy harvesters. |
