A solid state drive apparatus includes a case including a base and side walls extending upward along a circumference of the base, an electrostatic prevention structure of a metal pillar spaced apart from the side walls and protruding from at least a partial surface of the base and an electrostatic absorbing member on at least a partial surface of the metal pillar, a package substrate module mounted on the electrostatic prevention structure in the case, and a cover covering the case and the package substrate module.

A cellphone signal enclosure system includes a faraday enclosure having an internal antenna, the internal antenna having a connector exposed on the exterior of the enclosure for coupling to a cable, the faraday enclosure prohibiting RF signals from exiting the faraday enclosure; and, a cable couplable to the connector, the cable coupled to an external antenna on its opposite end. The external antenna sends and receives signals, via the cable, to the internal antenna, the internal antenna being in communication with a wireless device (e.g., cellphone, smartwatch, tablet, etc.) inside the faraday enclosure. In some examples, the external antenna and the cable are detachable, allowing customization for a user's needs. In some examples, the cellphone signal enclosure includes a touch-sensitive window and blue light filter that reduces eye strain, while still blocking RF signals.

Encapsulated PCB assembly (1) for electrical connection to a high- or medium-voltage power conductor in a power distribution network of a national grid, comprising a) a PCB (10), delimited by a peripheral edge (20) and comprising a high-tension pad (60, 62) on a voltage of at least one kilovolt, b) an electrically insulating encapsulation body (70) in surface contact with, and enveloping, the high-tension pad and at least a portion of the PCB edge adjacent to the high-tension pad, c) a shielding layer (80) on an external surface (90) of the encapsulation body and for being held on electrical ground or on a low voltage to shield at least a low-voltage portion of the PCB. The high-tension pad extends to the peripheral edge of the PCB.

An electromagnetic pulse (EMP) resistant telecommunications (telecom) system includes core components mounted within and shielded by a Faraday cage. The components include a data source or storage device. An ethernet switch selectively connects the data source or storage device to a primary satellite router and a post-EMP satellite router. Telecom signals are output from and input to the core components via low noise blocks (LNBs) and block upconverters (BUCs). A method of resisting EMP interference for a telecommunications system includes the steps of enclosing and shielding core components in a Faraday cage and providing output via LNBs and BUCs to an antenna subsystem. The antenna subsystem can include one or more antenna elements with configurations chosen from the group comprising: parabolic dish; array; unidirectional; and omnidirectional. The EMP-resistant telecom can optionally be combined with a signal regenerating subsystem and used with a signal regenerating method.

A secondary electrochemical battery sealing body, including a negative electrode cap, a circuit board module, and an insulating gasket. A battery case has a recessed wire turn structure at an end thereof adjacent to the negative electrode cap. The circuit board module is located between the wire turn and the negative electrode cap, and multiple electronic components are arranged thereon. The negative electrode cap and the circuit board module constitute a first enclosed electromagnetic shielding space. The battery case and the circuit board module constitute a second enclosed electromagnetic shielding space. The electronic component is provided within the first enclosed electromagnetic shielding space and the second enclosed electromagnetic shielding space. The insulating gasket has a “” shape in section, and is disposed within gaps of the battery case, the circuit board module and the negative electrode cap.

A data center rack includes a housing, at least one wireless access point (AP) mounted within the housing and wirelessly connectable to a network switch external to the housing, and at least one tray including a plurality of mobile device power connections to provide power to a plurality of mobile devices.

Embodiments relate to materials and methods for manufacturing the materials for an enclosure that houses one or more electronic devices. In some embodiments, the materials include a tuned micro-lattice that includes one or more metallic materials defining a micro-lattice configuration. In some embodiments, the one or more metallic materials extend over at least a portion of an elastomeric material. In some embodiments, the materials include a tuned composite metallic foam including one or more metallic materials. A first portion of the foam has a first porosity and a second portion of the foam has a second porosity. In some embodiments, the materials for the enclosure are one or more of a gasket and a coating that extends over a least a portion of an interior portion of the enclosure.

What is provided is a shield housing for shielding interconnect structures and/or components disposed on a circuit board, wherein at least two antenna radiators can be disposed on the shield housing, and wherein the shield housing is configured in such a manner that it can cover the interconnect structures and/or components disposed on the circuit board, at least in part, can be connected with a ground surface of the circuit board, and has a region between the antenna radiators, which region is configured in such a manner that it provides electrical decoupling of the feed of the antenna radiators from one another.
