Abstract: Mobile management method, system and client. Method includes receiving a DNS query for a host name from an application on client; retrieving reputation data associated with host name from a local cache on client; and determining a policy based on host name and the reputation data. Based on determined policy for the host name, blocking attempted network flows to a host corresponding to host name to produce blocked attempted network flows. Method also includes sending attempted network flow metadata related to the blocked attempted network flows to a collector on client; transmitting the attempted network flow metadata from the collector to a VPN server pool via a VPN tunnel; and producing an anomaly report from the transmitted attempted network flow metadata. The anomaly report includes at least one of anomalies, cohorts, trends, location boundaries, detected network security issues, detected compromised clients and/or optimized network usage.

Abstract: A driver can be configured to provide sensed phase currents as feedback to a controller to indicate the output currents from each phase of a switch mode power supply (SMPS). The driver can be configured to temperature compensate the sensed currents in one of two ways. If a temperature sensor is directly coupled to the driver, then the driver may be configured to temperature compensate the sensed currents from each phase based on a temperature measurement made by the temperature sensor. If a temperature sensor is not directly coupled to the driver, then the driver may be configured to temperature compensate the sensed current from each phase based on a temperature signal received from a bus coupled to the driver. The bus can communicate the temperature signal so that multiple drivers can utilize one temperature sensor.
