Uninterruptible power supply device
In a first power feeding mode, a controller supplies AC power output by an inverter to a load. In a second power feeding mode, the controller supplies AC power supplied from an AC power supply to the load. The controller switches an operation mode to the first power feeding mode when a voltage drop of the AC power supply is detected during the second power feeding mode. The controller, for a prescribed time period from detection of the voltage drop, causes a converter to perform reverse conversion to convert DC power output by a power storage device to AC power, and controls the reverse conversion in the converter such that an instantaneous value of an AC voltage output from the converter becomes equal to or higher than an instantaneous value of an AC voltage output from the inverter. |

Dynamic cybersecurity peer identification using groups
Cybersecurity peer identification (CPI) technology obtains security group definitions from an identity directory, computes peerSimilarityScores that represent user similarity in terms of security permissions, and submits contextual cybersecurity peer data to cybersecurity peer-based functionality (CPBF). CPBF code may then perform behavior analytics, resource management, permissions management, or location management. Cyberattacks may then be disrupted or mitigated, and inefficiencies may be avoided or decreased. Having smaller security groups in common gives users higher peerSimilarityScores than having larger groups in common, as a result of logarithmic, reciprocal, or other score functions. Security group definitions are refreshed and peer scores are updated at regular intervals or on demand by CPI code, to avoid staleness. CPI code may be tuned by varying update intervals, varying cutoffs imposed on the size of security groups deemed suitable for use in computing peerSimilarityScores, or varying other parameters. |
