The present disclosure relates to a hybrid cooling system for electronic enclosures that can incorporate both liquid and air-based cooling mechanisms within a single structure. The system can include a thermal transfer assembly that facilitates heat transfer between liquid-cooled and aircooled components, allowing for efficient thermal regulation across multiple heat-generating components with different cooling requirements. The thermal transfer assembly can include a thermally conductive plate, which can be fluidly associated with a coolant medium, and a set of heat-absorbing elements that can extend into an enclosed volume. The system can be configured to dissipate heat from a first heat-generating component through direct thermal coupling with the thermally conductive plate while transferring heat from a second heat-generating component positioned within the enclosed volume.

A voltage converter (10) comprises a first voltage converter side (11), a second voltage converter side (12), a top DC/DC converter (20) with a first top side (21) and a second top side (22), a bottom DC/DC converter (30) with a first bottom side (31) and a second bottom side (32), a switching circuit (13), and a controller (14). The first top side (21) and the first bottom side (31) are coupled in parallel to the first voltage converter side (11). The controller (14) controls the switching circuit (13) such that the second top side (22) and the second bottom side (32) are coupled to the second voltage converter side (12) in parallel in a parallel operation (OP) or in series in a series operation (OS). Moreover, a method for controlling a voltage converter (10) is provided.

A hybrid circuit interrupter includes a primary inductor, a mechanical switching element coupled to the primary inductor, and a solid-state switching circuit coupled to the primary inductor and connected in parallel with the mechanical switching element, wherein the solid-state switching circuit is structured and configured to commutate current away from the mechanical switching element during a fault condition, and wherein the solid-state switching circuit includes a secondary inductor, a first number of power electronics elements in series with the secondary inductor, and a second number of power electronics elements structured and configured to regulate current through the mechanical switching element.

A field installable rejection interlock system (100) including a breaker kit (110) and a cassette kit (160) prevents insertion of a drawout circuit breaker into an electrically incompatible frame. The breaker kit (110) gets installed on the breaker exterior and includes a side mounting plate (111), an actuator blade (115), and a slider plate (120). The cassette kit (160) gets installed in the cassette interior and includes a mounting bracket (161), a driven lever (165) with an L-bracket (167) attached, and a ramp (170). In their default states, the driven lever (165) is positioned with the L-bracket (167) obstructing movement of the incompatible circuit breaker into the cassette, or the slider plate (120) is positioned to obstruct movement of the breaker into the incompatible cassette. In the case of a combination of a compatible breaker (51) and cassette (52), the ramp (170) pushes the slider plate (120) to remove the first obstruction/interlock, and the actuator blade (115) actuates rotation of the driven lever (165) and L-bracket (167) to remove the second obstruction/interlock.

A PFAS-free hose is provided comprising an electrically conductive polyimide or PEEK innermost layer, optionally an adhesive tie layer, and a silicone tube layer. The conductive polyimide or PEEK innermost layer includes an electrically conductive filler and exhibits good electrical conductivity, is compatibility with aerospace fluids, and exhibits thermal stability, flexibility, and compatibility with outer tube layer when co-extruded.

A device bracket (1) for supporting and carrying a data communication device comprises a frame (100) being formed to provide a support for supporting and carrying the data communication device. The frame (100) has a structure (200) for providing cable management for a cable

A shutter assembly includes a slider slidable in a first direction relative to a cassette, and first and second arms coupled the slider and the cassette that are independently slidable in the first direction relative to the slider and the cassette and pivotable relative to the slider and the cassette, and shutter plates coupled to the arms such that are movable between a closed condition and an open condition wherein the apertures of the shutter plates are aligned with one another and the of terminals of the cassette. The slider includes a locking portion structured to enable the slider to be padlocked to a member extending from the top surface of the cassette. The shutter assembly also includes a latching mechanism for latching the shutter assembly in the open condition.

A vandalism detection and alert system (VDAS) is provided for an EV charging network monitored by a charge point operator (CPO). The VDAS is designed for use with a network whose EV charging stations use connector cables that include NTC cables to monitor over-temperature conditions. The VDAS includes an NTC monitoring logic module that continuously monitors each NTC cable in a given charging station. If there is a discontinuity in the communication path between an NTC cable and the NTC monitoring logic, the connector cable has likely been vandalized. The discontinuity causes an alarm to be issued in the specific charging station where the cable was vandalized and also causes an alert to be sent to the CPO. The CPO then issues a Panic Alarm command to all other charging stations associated with the site, causing all charging stations at the site to actuate their alarms.

The optical coupling element (1) comprises a housing (11) and a light guidance element (12) configured to guide light from a light-emitting element (2) to a user interaction element (3). The light-emitting element (2) is arranged on a carrier element (5). The user interaction element (2) is fixedly connected to a mounting adapter (4) via a first clip connection (41) and the carrier element (5) is fixedly connected to the mounting adapter (4) via at least two fastening elements (42). The housing (11) is fixedly connected to the mounting adapter (4) via a second clip connection (43). The light guidance element (12) is directly subordinated to the light-emitting element (2) in a main emission direction (20). The optical coupling element (1) is provided without mechanical fixation to the carrier element (5). The housing (11) and the light guidance element (12) are each formed in one piece, and the housing (11) and the light guidance element (12) comprise different materials.

An improved emergency pedestal includes a lighting projection device to increase visibility and identifiability of the emergency pedestal. The lighting projection device is separate from an illumination lens that provides lighting to illuminate the area around the emergency pedestal. The lighting projection device is configured to project an illuminated image on a nearby ground surface. The illuminated image depicts a fire extinguisher and/or text or other imagery that identifies the emergency pedestal as specifically being an emergency pedestal. Projecting the illuminated image helps a user to clearly differentiate the emergency pedestal from other outdoor pedestals such as power pedestals, especially in low ambient lighting or low visibility conditions.
