A shield assembly includes a closing structure configured to be disposed over an opening of an enclosure. The closing structure includes an inner surface configured to face an inside of the enclosure when the closing structure is closed and a finger bracket structure mounted on the inner surface, the finger bracket structure having a bracket and one or more finger gaskets coupled to the bracket. An electromagnetic interference (EMI) shielded gasket disposed along a portion of the opening of the enclosure shields an edge of the opening of the enclosure or a radio frequency (RF) fence bracket coupled to a frame disposed around the opening of the enclosure creates a narrow path between the frame and the closing structure, the narrow path attenuating RF signals passing through the narrow path and shielding an edge of the opening of the enclosure.

A method according to one embodiment includes securing a first plurality of conductive sheets to a surface, applying a conductive tape to a first plurality of joints between conductive sheets of the first plurality of conductive sheets, and securing a second plurality of conductive sheets to the first plurality of conductive sheets without fully penetrating the first plurality of conductive sheets. In such an embodiment, each of a second plurality of joints between conductive sheets of the second plurality of conductive sheets is offset relative to the first plurality of joints.

A door assembly is described. The door assembly includes a door structure that is mounted over an opening of an enclosure. The door structure includes a body that includes a first surface and a second surface opposite to the first surface. The first surface may face an inside of the enclosure when the door structure is closed. The door structure includes a number of finger bracket structures mounted on the first surface. Each one of the finger bracket structures includes a bracket and one or more finger gaskets coupled to the bracket. The finger gaskets of the finger bracket structures may contact enclosure brackets mounted around an edge of the opening of the enclosure when the door structure is closed. A combination of the finger gaskets in contact with enclosure brackets may create an electromagnetic interference (EMI) shield at the edge of the opening of the enclosure.

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.

A flexible touch sensor having a visible area and a trace area surrounding the visible area includes a substrate, a touch-sensing layer, and a noise shielding layer. The substrate has a first surface and a second surface facing away from the first surface. The touch-sensing layer is disposed on the first surface of the substrate. The noise shielding layer is disposed on the second surface of the substrate. The noise shielding layer includes a matrix and a plurality of metal nanowires distributed in the matrix.

A modular computer case includes a horizontal computer case, a case cover arranged on the opening of the computer case, forming an air exchange system on the case cover; an assembling bracket kit, forming a modular base with the case cover; a predetermined monitor which can be installed on the computer case to form a modular computer case sharing monitor assembling bracket with power supplier, and the front section of the case cover has multiple air suction holes for sucking in the external air and exhausting through the heat dissipation through holes arranged at the rear section of the case cover, so as to form a high-speed cooling ventilation system.

A data center equipment rack includes an electronic equipment enclosure defined by RF-shielded walls. Openings in the RF-shielded walls are provided for being aligned with complimentary-sized and shaped openings in one or more like data center equipment racks and adapted for permitting a shielded electromagnetic connection between two or more racks. At least one access door in the enclosure is provided for facilitating access to the electronic equipment in the rack. Panels are provided for covering the respective openings in the RF-shielded walls when the openings are not being used to permit an electromagnetic interconnection between two or more racks.
