Traffic on-boarding for acceleration through out-of-band security authenticators
A traffic on-boarding method is operative at an acceleration server of an overlay network. It begins at the acceleration server when that server receives an assertion generated by an identity provider (IdP), the IdP having generated the assertion upon receiving an authentication request from a service provider (SP), the SP having generated the authentication request upon receiving from a client a request for a protected resource. The acceleration server receives the assertion and forwards it to the SP, which verifies the assertion and returns to the acceleration server a token, together with the protected resource. The acceleration server then returns a response to the requesting client that includes a version of the protected resource that points back to the acceleration server and not the SP. When the acceleration server then receives an additional request from the client, the acceleration server interacts with the service provider using an overlay network optimization. |

Very high efficiency soft switching converter AKA the adjud converter
In this invention we introduce the concept of a soft switching half bridge switching cell wherein the soft switching is guaranteed by the magnetizing current. Further this soft switching half bridge cell contains at least two synchronous rectifiers in the secondary which are conducting together during the dead time of the primary switchers creating a short circuit across the secondary windings, trapping the magnetizing current and release the magnetizing current to discharge the parasitic capacitances across the primary switchers when the synchronous rectifiers turn off. The secondary windings are connected to a synchronized and controlled current source. The current demanded by the current source is shaped in such way that the current becomes zero before the synchronized rectifiers turn off, allowing the magnetizing current to discharge the parasitic capacitances of the primary switching elements in a monotonic way and create zero voltage switching conditions for the primary switchers and further charge in a monotonic way the parasitic capacitances of the secondary synchronous rectifiers without ringing and spikes. By shaping the current of the synchronized current source to reach zero before the secondary synchronous rectifiers turn off, soft switching is maintained in the half bridge cell under all line and load conditions.In one of the key embodiments the current of the synchronized current source will reach zero before the primary switchers turn off. In such configuration the dead time between the conduction of the primary switchers can be reduced to the transition time.This invention is proposing different ways to shape the current of the current source, some of the configuration being forward derived and some of them boost derived. These technologies are suitable also for bidirectional power transfer and for multiple independent outputsThe family of converters derived from the soft switching half bridge cell can be applied in many power conversion applications especially at high frequency due to guaranteed soft switching in all the line and load conditions.The methodologies of shaping the current of the syncroniosed current source do apply also to other topologies such as single ended forward converters. |

Metal liner passivation and adhesion enhancement by zinc doping
A method comprises depositing a barrier layer on a dielectric layer to prevent oxidation of a metal layer to be deposited by electroplating due to an oxide present in the dielectric layer and depositing a doped liner layer on the barrier layer to bond with the metal layer to be deposited on the liner layer by the electroplating. The dopant forms a protective passivation layer on a surface of the liner layer and dissolves during the electroplating so that the metal layer deposited on the liner layer by the electroplating bonds with the liner layer. The dopant reacts with the dielectric layer and forms a layer of a compound between the barrier layer and the dielectric layer. The compound layer prevents oxidation of the barrier layer and the liner layer due to the oxide present in the dielectric layer and adheres the barrier layer to the dielectric layer. |
