A technique for measuring, evaluating, and presenting virtual network connection latency and virtual network connection stability information allows users to easily evaluate the quality of internet connections in real time. In accordance with some of these principles, a voltage regulator is disclosed having multiple feedback loops, each responding to transients with different speeds, that operate in parallel to adjust an output current of the regulator in response to variations in the output currentvoltage due to, for example, variations in a supply voltage andor variations in a load current. Other callers will hear a busy signal or may be routed to voicemail. The direct access server verifies an Idle command functionality on the communications channel before relying on the communications channel for new mail notifications. A second microphone can be positioned in a second ear canal and the two microphones preserve and deliver inter-aural sound level and phase differences that naturally occur so that the user can perceive directionality. The method also includes the step of determining the likelihood of drift in the sensed load W in response to the determined rate of change {dot over },{dot over }avg.
