  • Patent number: 10554588
    Abstract: In some implementations, a method includes analyzing an amount of data communicated by a set of network interfaces. The data communicated by the set of network interfaces is processed by a set of functional units and a set of queues includes the data communicated by the set of network interfaces. The method also includes activating a first functional unit of the set of functional units when a first size of a first queue of the set of queues is above a first threshold. The method further includes deactivating the first functional unit of the set of functional units when the first size of the first queue of the set of queues is below a second threshold. The method further includes causing the data to be forward to one or more active functional units via a data interconnect coupled to the set of network interfaces and the set of functional units.

  • Patent number: 9905354
    Abstract: An electrical device includes a core structure having a first core section, a second core section, and a third core section. The electrical device further includes a first coil electrically coupled to the first core section and the second core section to form a choke and a primary winding of a transformer. The choke is configured to reduce common mode noise for an electrical signal received by the electrical device, and the primary winding of the transformer is configured to induce a magnetic field on the third core section. The electrical device also includes a second coil electrically coupled to the third core section, which forms a secondary winding of the transformer and receives electromagnetic energy from the magnetic field induced by the primary winding of the transformer.

  • Patent number: 8835775
    Abstract: Techniques are provided for electrically connecting components on a printed circuit board (PCB), semiconductor chip package, or other electronic device. More specifically, a first component, configured to generate a differential signal, is disposed on the PCB, while a second component, configured to receive the differential signal from the first component, is also disposed on the PCB. A differential conductor pair comprising first and second parallel conductors extends along a path between the first and second components. The path of the differential conductor pair comprises at least one turn that causes a change in direction of the first and second conductors. The first conductor comprises at least one localized skew compensation bend disposed at the turn such that, at the end of the turn, the first and second conductors have substantially the same length with respect to the first component.
