  • Patent number: 10657033
    Abstract: Embodiments presented herein describe techniques for tracking operators of a distributed computing environment (e.g., a streams processing environment) using metadata. During execution of a distributed application of the computing environment, a tracker tool monitors a plurality of operators of the distributed application. Each of the operators stores one or more specified metadata values associated with the operator. For each operator, the tracker tool retrieves the one or more specified metadata values associated with the operator. Upon determining that one of the one or more specified metadata values do not comply with a corresponding expected metadata value, the tracker tool generates an indicator for the operator. The indicator includes information describing the one or more specified metadata values.

  • Patent number: 10659113
    Abstract: A source wireless access node serves User Equipment (UEs) over a Three-Dimensional (3D) Multiple Input Multiple Output (MIMO) antenna array and over a Two-Dimensional (2D) MIMO antenna array. The source wireless access node wirelessly exchanges user data with the UEs over the 3D MIMO antenna array. The source wireless access node detects a loss-of-synchronization. The source wireless access node detects an interference condition at neighbor wireless access nodes. When the interference condition at the neighbor wireless access nodes and the loss-of-synchronization at the source wireless access node occur simultaneously, the source wireless access node network disables the 3D MIMO antenna array and wirelessly exchanges additional user data with the UEs over the 2D MIMO antenna array. When the neighbor interference condition or the loss-of-synchronization terminate, the source wireless access node enables and uses the 3D MIMO antenna array.

  • Patent number: 10587424
    Abstract: In a PoDL system, a PHY has its I/O terminals coupled to a wire pair via a galvanic isolation transformer and a CMC. Thus, DC power and common mode noise are blocked from the PHY inputs. One end of the secondary winding of the transformer is directly coupled to one winding of the CMC. A DC power supply has its positive voltage terminal directly coupled to the other end of the secondary winding and has its other output terminal (e.g., ground) directly coupled to the other winding of the CMC. An AC-coupling capacitor is coupled between the two outputs of the power supply. Differential signals are applied across the secondary winding to couple the differential signals to the PHY, while the secondary winding conducts the DC voltage to one of the wires (via the CMC), and the ground is coupled to the other one of the wires (via the CMC).
