A computer-implemented method for transforming security advisories into targeted actionable mitigation strategies is provided. The method includes receiving a security advisory describing a vulnerability, processing the security advisory using a first language learning model (LLM) to extract vulnerability characteristics, generating an interaction model of sub-systems within a target system based on a topology of the target system, generating at least one actionable mitigation strategy for the vulnerability using a fine-tuned second LLM based on the extracted vulnerability characteristics and the interaction model, and outputting the actionable mitigation strategy as a security enhancement implementable on the target system. The method enables customized security enhancements for systems lacking official patches or manufacturer support.

Systems for method for a semiconductor-based DC transfer switch. The semiconductor-based DC transfer switch uses two individual circuit breakers that are mechanically interlocked in such a way that only one of the two circuit breakers can be closed at any time. An actuator, such as a motor, operates mechanical arms that interact with the handles of the circuit breakers. At least one of the circuit breakers is a semiconductor-based DC circuit breaker.

A building controller and a method thereof routes serial traffic in a building management system. Non-IP serial traffic is read from a non-IP network of building devices managed by the building controller and forwarded to a building network stack operating on the building controller. The building controller performs building controller operations based on data stored at the building network stack. The non-IP serial traffic is also mirrored to a frame router operating on the building controller in response to detecting that remote traffic monitoring has been enabled. The frame router identifies a destination interface of the building controller to route the non-IP serial traffic and generates a data packet that includes the non-IP serial traffic and an IP header. The data packet is provided to an IP network of building management devices connected to the building controller, including a remote device which has a serial traffic analyzer.

An automated EVSE group commissioning system comprises a centralized system to supply a series of known valid SSID and password credential combinations to a group of EVSEs. The centralized system to assist in a group pre-connectivity configuration in that if the group of EVSEs is in a same area, they default to connect to each other via a WLAN created by a parent EVSE, to which each child EVSE connects. A first EVSE comprises instructions to commission the first EVSE in the group of EVSEs that is interconnected. Every subsequent EVSE in that local network connectivity group is automatically commissioned such that for every group of EVSEs, the only activity that needs to be performed is a single EVSE commissioning and the system does not require subsequent EVSEs of the group of EVSEs to be network configured for them to be added to the certain company account.

A residential electrical load center including an interlock accessory is configured to distribute electrical power to all different circuits by bus bars for an electrical vehicle (EV) application. The residential electrical load center comprises a main circuit breaker that is configured to protect the bus bars from potential overloads and or short circuits, a plurality of branch circuit breakers that are connected to the bus bars and are configured to protect individual circuits for each load of a plurality of loads and an interlock accessory that is configured to interlock two branch circuit breakers of the plurality of branch circuit breakers together so that both branch circuit breakers cannot be “ON” at the same time which allows one branch circuit breaker to be connected to a selected load (e.g. a clothes drier, an electrical range, etc.), while the other is connected to an electrical vehicle charger.

A fire protection system synchronizes fire panels and notification appliances. A Standard Ethernet Cable couples to a first fire panel to a second fire panel. Each of the first and second fire panels is coupled to a group of fire alarm notification appliances by a notification appliance circuit. The Standard Ethernet Cable communicates first data relating to the fire alarm notification appliances between the first and second fire panels. The Standard Ethernet Cable has a connector including a center tap for communicating second data relating to the fire alarm notification appliances between the first and second fire panels.

A circuit breaker accessory for reverse handle operation of a circuit breaker installed in a vertically inverse orientation includes a housing configured for attachment to a face of a circuit breaker on which a switching handle of the circuit breaker is arranged. A reverse switching handle is configured with a transverse sleeve for a pivot axis of operation between a down position and an up position with a top to protrude through the housing. An extension arm has a pivoting connector at a first end for coupling with the bottom end of the reverse switching handle, and a collar at a second end for coupling with the switching handle of the circuit breaker. A pivot shaft couples the transverse sleeve of reverse switching handle with the housing, arranged to fit through the transverse sleeve. The reverse switching handle operates in a direction opposite to the switching handle of the circuit breaker due to extension by the extension arm.

A direct current (DC) switch circuit includes an isolation switch, and an interruption circuit connected in series with the isolation switch. The interruption circuit includes a parallel connection of a current conducting branch, a bypass power electronics branch, a gate driving branch, and an energy absorbing branch. The current conducting branch includes a multi-throw switch configured to operate in a first position to establish a first electrical connection between the current conducting branch and a load and a second position to establish as second electrical connection that turns off the bypass power electronics branch.

There is described a controller and method for managing a flow unit. A measured pressure drop corresponding to a full open position of a flow control element is detected. A calibration pressure drop at full open is established based on the measured pressure drop, and relative pressure drops are calculated based on the calibration pressure drop at full open and calibration pressure drops corresponding to calibration positions of the element. Subsequent to calibration, an operation pressure drop of the flow unit and an operation position of the element are detected. A dynamic nominal is determined based on the operation pressure drop and a particular relative pressure drop corresponding to the operation position. An operation relative flow and a relative flow setpoint are determined based, in part, on the dynamic nominal. The operation position of the flow control element is controlled based the operation relative flow and relative flow setpoint.

A DC solid-state circuit breaker includes a power electronics section, an airgap section, and a sensing and control circuit. The power electronics section includes a first solid-state switching component. The airgap section is connected in series with the power electronics section to establish a main current path. The airgap section implements an isolation switch connected in series with a fail-safe interruption circuit that includes a current commutation switch, a second solid-state switching component, and an overvoltage protection device connected in parallel with one another. In response to detecting a fault event and/or an opening command, the sensing and control circuit performs a fail-safe operation that controls the isolation switch at a time period, and controls the current commutation switch and the second solid-state switching component at a delayed time period that occurs after controlling the isolation switch.
