  • Patent number: 9867240
    Abstract: A filter circuit comprising a first feedback circuit configured to: receive a sensed-voltage-level-signal representative of a sensed voltage across a current sensing element; receive a voltage-set-point-signal; and set a regulation-control-signal for a current regulation device such that the sensed-voltage-level-signal tends towards the voltage-set-point-signal. The filter circuit also comprises a second feedback circuit configured to: receive a predetermined-threshold-signal; and receive a regulation-control-voltage-signal, representative of a voltage level of the regulation-control-signal. The second feedback circuit is configured to adjust the voltage-set-point-signal in accordance with a comparison between the regulation-control-voltage-signal and the predetermined-threshold-signal.

  • Patent number: 9866491
    Abstract: A mechanism is provided by which communication is reduced between a data plane of a network device and a control plane associated with that network device upon introduction of a new flow. A holding table is provided for every active flow table in the data plane. The holding table holds flow contexts for new flows not found in the associated active flow table, while awaiting flow information from the control plane. Each flow context includes a queue of subsequent data packets associated with the flow, which are held from the control plane pending receipt of the flow information from the control plane. A timeout mechanism compensates for packet loss between the network device and control plane. When the data plane receives the flow information from the control plane, the data plane then processes all the queued packets, deletes the flow context, and enters the data into an associated flow table.

  • Patent number: 9857435
    Abstract: A sensor package includes a magnetic field sensor and a corruption detection and reset subsystem. The magnetic field sensor has a magnetic sense element and a ferromagnetic structure characterized by a baseline magnetic state. The subsystem includes a detector element, a processor, and current carrying structure positioned in proximity to the ferromagnetic structure. Methodology performed by the subsystem entails detecting at the detector element an altered magnetic state of the ferromagnetic structure, where the altered magnetic state differs from the baseline magnetic state. Methodology further entails determining, at the processor, when a reset action is needed in response to the altered magnetic state and applying a reset magnetic field to the ferromagnetic structure to reset the ferromagnetic structure from the altered magnetic state to the baseline magnetic state.
