A circuit card assembly including a printed circuit board arranged to include one or more electronic circuits and a frame connected to the printed circuit board. The circuit card including at least one connector arranged to detachably engage with a backplane connector of the electronic chassis to establish an electrical connection with a backplane printed wiring board (PWB) of the electronic chassis. The circuit card also including a front panel having at least one input/output connector and an EMI/RFI gasket positioned along a perimeter of the back side of the front panel where the EMI/RFI gasket is arranged to contact a surface of the electronic chassis along a perimeter of the circuit card assembly slot when the circuit card assembly is extended into the circuit card assembly slot.

A housing device for isolating electromagnetic interference emitting devices includes a structural frame. The structural frame of the housing device is for housing the electromagnetic interference emitting devices. The housing device further includes an electromagnetic interference isolating enclosure. The electromagnetic interference isolating enclosure of the housing device is non-structural. The electromagnetic interference isolating enclosure of the housing device is for encapsulating the structural frame.

A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated. The data processing device further includes an electromagnetic radiation (EMR) suppressing vent that defines one wall of the internal volume. The data processing device further includes a wireless system. The wireless system includes a first portion that is disposed in the internal volume. The first portion receives network data units from EMI emitting devices disposed in the internal volume and a second portion of the wireless system. The second portion is disposed outside of the internal volume and obtains the network data units from the first portion using a wireless connection that utilizes a transmission path that traverses through the EMR suppressing vent.

A modular system of plastic walls having embedded and coextensive electrically conductive components configured to electrically connect with each other when the walls are mated. The walls have joining edges that form joint seams with other walls when joined together to create an enclosure. When enough walls are used to surround a storage space, a Faraday cage is created. The walls additionally have portions of tortuous paths at each joining edge that mate with a complementary portion of a tortuous path of another wall when the walls are joined together. A torturous path seal is thereby created at each joint seam. The plastic walls can be configured in a multiplicity of combinations to create various enclosures necessary for RFID-enabled storage and tracking of medical articles. Containers, enclosures, cabinets, and drawers of differing heights and sizes can be made and they may be stacked or otherwise assembled.

A filter design configured to operate in the medium voltage range of 1000 to 5000 volts, provides protection against Electromagnetic Pulse/High Altitude Electromagnetic Pulse (EMP/HEMP) intentional electromagnetic interference pulses. The filter utilizes no oil filled components to preclude the catastrophic failures (explosions) during operation. Many of the components incorporated in the present design are suited to absorbing harmonics without failing. In addition to mitigating E1 and E2 pulses, the filter is resistant to line harmonics which have proved to cause filter failure in past designs. The filter provides EMP/HEMP conducted pulse protection for downstream electronics inside hardened shelters for medium and high voltage applications.

An information handling system to wirelessly transmit and receive data may include a base chassis including a metal C-cover and metal D-cover to house a processor, a memory, and a wireless adapter, the metal C-cover to house a speaker grill, the speaker grill covering a speaker to emit audio waves; the speaker grill formed within the C-cover to emit a target radio frequency (RF) including a slot formed around a portion of the speaker grill forming a peninsula on the speaker grill that is physically separated from the C-cover; an antenna element placed behind the speaker grill and operatively coupled to the wireless adapter; an electromagnetic interference (EMI) shield forming a cavity enclosing the speaker and the antenna element, including a plurality of metallic shielding walls extending from the C-cover to a D-cover of the information handling system; and a conductive rubber gasket placed between the plurality of conductive walls and the D-cover to shield the cavity from EMI sources.

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 shield case including a base portion made of a nonmetal material and having a mounting surface on which the electronic component is mounted, a cover portion made of a metal material and covering surroundings of the electronic component and a metal plate abutting with an outer surface of the base portion and having an end portion projecting outward from the base portion. A side-wall end portion of the cover member includes a first end abutting with the mounting surface of the base portion, and a second end extending in a thickness direction of the base portion and abutting with the end portion of the metal plate.

An exemplary electromagnetic shielded dry bag with magnetic closure system includes an outer bag, an inner shielding liner, and a pair of embedding strips having magnets embedded therein. The outer bag is preferably comprised of water-proof material and has a fluid-sealed floor portion and an access mouth disposed oppositely thereof. First and second bag panels are disposed oppositely of one another and extend from the floor portion to the access mouth. The inner shielding liner is comprised of electromagnetic shielding material and defines an electromagnetic shielding compartment within the bag. The embedding strips are secured to respective bag panels. This securement may be by way of heat fusing of respective securement elements to the inner faces, thereby forming pockets with which the strips reside. When the closure section is magnetically retained in closed configuration, the access mouth is thereby retained in an RF-sealed and fluid-sealed configuration to protect the shielding compartment.

An information handling system to wirelessly transmit and receive data may include a base chassis including a metal C-cover and metal D-cover to house a processor, a memory, and a wireless adapter, the metal C-cover to house a speaker grill, the speaker grill covering a speaker to emit audio waves; the speaker grill formed within the C-cover to emit a target radio frequency (RF) including a slot formed around a portion of the speaker grill forming a peninsula on the speaker grill that is physically separated from the C-cover; an antenna element placed behind the speaker grill and operatively coupled to the wireless adapter; an electromagnetic interference (EMI) shield forming a cavity enclosing the speaker and the antenna element, including a plurality of metallic shielding walls extending from the C-cover to a D-cover of the information handling system; and a conductive rubber gasket placed between the plurality of conductive walls and the D-cover to shield the cavity from EMI sources.
