COMPUTER SYSTEM AND METHOD FOR CLASSIFYING ASSETS IN AUTOMATED AND INDUSTRIAL CONTROL SYSTEMS
Classifying one or more assets in an automated and industrial control system (AIC) according to a classification standard. In a computer monitoring tool, a classification query is received for an asset managed by the AIC.

Systems/methods for fuzzy testing provide internal monitoring or a device under test (DUT) as/while test inputs are being processed by software running on the DUT. The systems/methods use a fuzz monitor agent that resides within the DUT to monitor for occurrence of crashes, failures, faults, exceptions, and other unexpected or undesired events or behavior caused by the software attempting to process the test inputs. The fuzz monitor agent logs the occurrence of any such events or behavior, then reports or otherwise provides the monitor log and any associated data to the fuzzing engine. To improve efficiency, the fuzz monitor agent can be compiled and run within the target DUT itself in some embodiments. This is particularly effective for testing embedded devices or other special function devices that are included within another device or as part of a larger overall system.
A fault managed power system (FMPS) and method therefor can limit the cumulative effects of repeated current pulses on the human body during a fault without changing the amplitudes of the current pulses. Upon detection of a fault, the fault managed power system progressively reduces the durations of the current pulses (i.e., ON intervals) instead of the amplitudes to limit the cumulative effects of the current pulses. The fault managed power system can perform the progressive pulse width reductions in increments or steps that limit the cumulative effects of the current pulses to below a predefined energy level. In some embodiments, the predefined level is a level that could prevent let-go or cause ventricular fibrillation in a human body. Such a fault managed power system advantageously provides a simple and efficient way to limit the energy delivered into a fault without having to change the amplitudes of the current pulses.

SYSTEMS AND METHODS FOR REDUCING ALARM NUISANCE BEHAVIORS IN AN ELECTRICAL SYSTEM
Systems and methods for reducing alarm nuisance behaviors in an electrical system are disclosed herein. In one aspect, a method for reducing alarm nuisance behaviors includes processing electrical measurement data from or derived from energy-related signals captured or derived by at least one intelligent electronic device in the electrical system to identify events in the electrical system, and alarms triggered in response to the identified events and/or other events in or related to the electrical system. Information related to at least the identified events and the identified alarms may be aggregated, and the aggregated information may be analyzed to identify at least one alarm nuisance behavior. At least one action may be taken or performed based on or in response to the at least one identified alarm nuisance behavior.
A fault managed power system (FMPS) and method monitors and detects fault currents in PoE, PFC, and other cables that indicate likely human contact with cable conductors. The level of current detected through the human body combined with a fast response time limits the energy to prevent a person from experiencing ventricular fibrillation, resulting in a so-called touch-safe level. For overload and short-circuit fault protection, the system automatically and immediately removes power from the cables. This limits the amount of energy provided into the fault, thereby maintaining touch-safe operation and also preventing electrical fires and system component protection. The system/method can accomplish this even at voltage levels considerably higher than existing touch-safe standards, for example, Class 2 (below 50 Vac) power supplies. Such a system/method allows the amount of power in applications like PoE and PFC to be safely increased to levels much greater than the current maximum (100 W).
