A junction box used for making electrical connections to a photovoltaic panel. The junction box has two chambers including a first chamber and a second chamber and a wall common to and separating both chambers. The wall may be adapted to have an electrical connection therethrough. The two lids are adapted to seal respectively the two chambers. The two lids are on opposite sides of the junction box relative to the photovoltaic panel. The two lids may be attachable using different sealing processes to a different level of hermeticity. The first chamber may be adapted to receive a circuit board for electrical power conversion. The junction box may include supports for mounting a printed circuit board in the first chamber. The second chamber is configured for electrical connection to the photovoltaic panel. A metal heat sink may be bonded inside the first chamber.

A display device includes: a display panel including a display area including pixels and a non-display area adjacent to the display area; a first driving integrated circuit including a first ground terminal, where the first driving integrated circuit is electrically connected to the display panel; a first printed circuit board electrically connected to the first driving integrated circuit; a first plate disposed on a bottom surface of the display panel and overlapping with the first driving integrated circuit; and a second plate disposed on the bottom surface of the display panel and spaced apart from the first plate, where the second plate is electrically connected to a system ground.

The cooling system includes a series of cooling channels arranged to provide convective cooling, with inserts for shielding electromagnetic interference (EMI) that is propagated by the waveguide nature of the cooling channels. Due to the relatively open nature, the cooling channels can serve to propagate EMI energy. The inserts mitigate the EMI exiting via these channels by attenuating or blocking the EMI. The inserts are shaped to block particular frequencies of EMI. The inserts may include thin sheet metal contoured to a half-wave profile, arranged along each cooling channel.

Heat sinks containing polymeric protrusions on a base and optionally further including a foil or tape, as well as methods of making and using thereof, are described herein.

A method of operating a public utility facility includes receiving a commodity at a processing facility communicably coupled to a control system that includes primary electrical components configured to operate the processing facility, and transitioning operation of the processing facility to an electromagnetic pulse mitigation module communicably coupled to the processing facility via a fiber optic line when the primary electrical components are rendered inoperable. The electromagnetic pulse mitigation module comprises a continuous conductive enclosure that is impervious to radiated and coupled electromagnetic energy. Operation of the primary electrical components is then assumed with one or more backup electrical components housed within the electromagnetic pulse mitigation module.

An electric power substation includes a circuit breaker that receives electrical power from a power plant, and a control house communicably coupled to the circuit breaker via a primary communication line, wherein one or more primary relay panels are housed within the control house. An electromagnetic pulse mitigation module is communicably coupled to the circuit breaker via a fiber optic line and comprises a continuous conductive enclosure that is impervious to radiated and coupled electromagnetic energy. One or more backup relay panels are housed within the electromagnetic pulse mitigation module and capable of assuming operation of the one or more primary relay panels.

An embodiment of a camera module may comprise: a lens part; a front body receiving the lens part; a rear body coupled to the front body; a substrate part received inside the rear body and comprising a plurality of printed circuit boards; a cable electrically connected to the substrate part; a connector part connecting the cable with the substrate part; and a first shielding part, made of a conductive material and disposed at a rear side of the connector part, for shielding electromagnetic noise generated from the substrate part or the outside.

A system and method for controlling an EMC protection apparatus in a removable component. The removable component is inserted into an end product. As a result of the insertion power is applied to the EMC protection apparatus. A determination is made as to whether a power good signal is detected within the removable component. In response to a power good signal, an EMC protection device is rotated from a retracted state to an engaged state such that the EMC protection device is placed over an enclosure opening in the removable component forming an EMC seal. Full functionality of the removable component can be delayed until such time as the rotation is completed.

Methods and apparatus for acoustically and electronically isolating a smart speaker to prevent unauthorized persons from using the smart speaker microphones to eavesdrop and intrude into a personal space.

The shield bracket refers to a shield bracket of open enclosure (2) delimited by a support structure (1) equipped with a main wall of support (3) and a containment structure (4), which is prepared to receive and serve as a support for communication devices (100), such as cell phones; the entire structure (1) or at least its walls of side screen (5), which are projected beyond the open enclosure (2), are structured in aluminum and therefore constitute barriers to the emission of electromagnetic waves coming from the devices (100) which support. Thus, this limits the emission zone (Z1) of these electromagnetic waves issued by the device of communication (100) and creates a wide area of the protection zone (Z2).
