A display device includes: a display panel; a driving integrated circuit chip configured to drive the display panel; a first printed circuit board connected to the display panel; a second printed circuit board connected to the first printed circuit board; and a cover including a body portion covering the driving integrated circuit chip, the first printed circuit board, and the second printed circuit board, and a wing portion protruding from the body portion, wherein the wing portion extends from a front surface of the display panel to a rear surface of the display panel while surrounding a side surface of the display panel.

Described herein is electromagnetic shielding that is configured to attenuate electromagnetic interference (EMI) by at least a threshold amount when the EMI has a frequency within a predefined frequency range. The electromagnetic shielding includes a layer of metal, such as aluminum foil, and a layer of thermoplastic polymer fabric (such as woven polyethylene fabric), where the electromagnetic shielding has several apertures that extend therethrough. The electromagnetic shielding is at least partially draped over electronic equipment that is to be shielded from EMI.

A Faraday enclosure apparatus may include one or more sewn seam portions constructed to prevent signal leakage through stitch apertures in the seam. A vestibule section facilitates signal-shielded movement of electronic devices between the ambient environment and the main cavity of the enclosure. A connector filter may be mounted to extend through a wall of the enclosure to manage wired power and signal communications entering and exiting the main cavity of the enclosure. Foldable side walls facilitate the collapsibility of the enclosure for compact transport and storage.

An exemplary faraday bag with magnetic closure system includes an actuatable closure section defined between a shielding compartment and an access mouth. The closure section preferably includes a retention segment, a distal flap segment, and an intermediate flap segment therebetween. Base magnets are disposed within the retention segment and a first panel of the bag. Flap magnets are disposed within the distal flap segment and a second panel of the bag. When the closure section is in open configuration, the flap magnets are substantially out of attractive magnetic engagement with respective base magnets, and the shielding compartment is accessible from an ambient environment through the access mouth. When the closure section is in closed configuration, the flap and retention segments are folded with respect to one another, the flap magnets are in attractive magnetic engagement with respective base magnets, and the access mouth is thereby retained in an RF-sealed configuration.

An electromagnetic tracking system includes a magnetic transmitter configured to output magnetic fields, a receiver responsive to the magnetic fields, an electronics assembly having conductive elements that cause distortion to the magnetic fields, and an output mechanism configured to output a position of the receiver relative to the magnetic transmitter, wherein the magnetic transmitter has at least one winding disposed around a hollow ferromagnetic core comprised of conductive material through which current is made to flow by the electronics, wherein the electronics assembly is at least partially contained within the hollow portion of the hollow ferromagnetic core. Methods of manufacturing include shaping walls into a hollow shell to surround an electronics assembly, covering the hollow shell with ferromagnetic material, inserting the wrapped hollow shell into a plastic bobbin, and winding the plastic bobbin with coil wire to produce three orthogonal windings.

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.
