Title: Method for enabling monitoring of power consumption

Abstract

Power consumption at a site is monitored. An electrical load is connected to a power source by an electrical conductor. A fuel-less energy producing device is electrically connected to a junction along the electrical conductor. A current sensor is electromagnetically coupled to the electrical conductor at a sensing position between the power source and the junction to create a current sensor signal. Sensed current and voltage signals are produced from the current sensor signal. A sensed phase relationship between the sensed signals is determined and compared to a baseline phase relationship to determine the direction of current flow through the conductor. A power source signal, based on the current flowing through the conductor at the sensing position, is created. With some examples a Rogowski type differential current sensor is used. In some examples a single current sensor is used.

System and method for monitoring power consumption to detect malware

Patent Prowell, Stacy J.; Nichols, Jeffrey A.; Hernandez Jimenez, Jarilyn M.

A system and method (referred to as the system) detects malware, viruses, and/or malicious activity by generating a direct current source power consumption profile by causing a monitored device to execute a fully automated recurrent software operation. The system receives by an automated detection system, the direct current source power consumption profile generated by an intelligent power sensor and generates by a detection engine, a power security profile that identifies suspicious code by profiling direct current consumed by monitored type devices. The system executes a detection engine remote from the monitored device that identifies an infected device.

Systems and methods for monitoring a power-generation module assembly after a power-generation module shutdown event

Patent Buenaventura, Don; Bowman, Doug

Embodiments are directed to providing a user interface (UI) that streamlines and simplifies the process of monitoring critical power-generation module (PGM) parameters after a PGM assembly is shutdown. The UI displays, in real-time, indicators corresponding to one or more post-shutdown PGM parameters. The UI provides indications of whether the post-shutdown PGM parameters meet post-shutdown criteria of the PGM assembly. When a post-shutdown PGM parameter does not meet the post-shutdown criteria, a user alert is provided to the user. A protocol may additionally be provided to the user. In some embodiments, the protocol may enable the user to return the PGMmore » « less
