An electromagnetic shielding lock box comprises an openable and closable box body. The box body is defined an accommodating groove, made by electromagnetic shielding materials, and has a lock unit and a hooking member. The box body is closed for receiving at least one key while the lock unit is in a locked status and for shielding the transmission of at least one electromagnetic wave signal due to the electromagnetic shielding materials. The lock unit is further limited the hooking member to be locked to the box body. The box body is opened for taking the at least one key out while the lock unit is in an unlocked status to unlock the hooking member from the box body.

The application relates to a receptacle comprising a plurality of inside pockets for holding objects, each of which is equipped with an RFID or NFC chip. At least two surfaces of the receptacle which include at least one of the plurality of inside pockets are provided with an electrically conductive layer so that the at least one of the plurality of inside pockets is shielded from electromagnetic radio waves by the at least two surfaces.

An encrypted multimedia streams transceiving method between a first and second user, includes using a device for transceiving multimedia streams connected to a respective electronic computer by both users; the method including a step of preventive activation of a free-to-air communication session between the users through a software for making multimedia communications within which the device operates in a first free-to-air transmission configuration, a step of creating an encrypted communication, within which the device operates in a second encrypted transceiving configuration; a step wherein the device causes the opening of a session for the transfer of encrypted data between the electronic computers, different from the free-to-air communication session used by the software for making calls, and at least audio data stream transceived between the two users during their communication is selectively switched between the free-to-air communication session and the encrypted data transfer session on the basis of a predefined criterion.

A molded composite battery enclosure containing top and bottom composite covers attached together. The joined top and bottom composite cover structures form an enclose or open area for housing a battery system of battery cells and cooling devices. The composite battery enclosures are lightweight and made of materials that can function to absorb energy and insulate the battery housing area. The composite structures contain a core material adhered and sandwiched between skin fiber layers and an electromagnetic shielding material or resin incorporated into one of the composite structures.

A personal communication device holder includes: a first housing component including a tubular data signal blocking body having a capped end and a male mating end; a second housing component including a tubular data signal blocking body having a capped end and a female mating end sized to receive the male mating end of the first housing component; a first liner material disposed on an inner surface of the first housing so as to leave an outer surface of the data signal blocking material of the male mating end exposed; a second liner material disposed on an inner surface of the second housing so as to leave an inner surface of the data signal blocking material of the female mating end exposed; and a data signal blocking gasket positioned between the exposed outer surface of the male mating end and the exposed inner surface of the female mating end.

The present invention relates to an EMF-screened plastic-organic sheet hybrid structural component, preferably a battery housing, and to its use in motor vehicles, preferably in electrically powered motor vehicles or hybrid motor vehicles, the abbreviation EMF meaning electromagnetic field(s).

A receptacle that houses electrical and electronic components and shields the components from harmful electromagnetic radiation uses a series of interspersed graphite layers with metal mesh and/or metal-coated carbon fiber layers in overlapping tape format that are fused together to form a laminate. In addition to the electromagnetic radiation absorption occasioned by the metal mesh layers, resonance chambers are formed within the laminate between adjoining metal mesh layers. The resonance chambers are tuned such that waves of certain frequencies are reflected away from the internal chamber of the receptacle while other wave frequencies are resonated within the resonance chambers. This allows the components of the receptacle to be shielded from incoming belligerent waves while allowing the dispatch of useful outgoing waves.

An EMC housing for an electrical component, having a first housing part and a second housing part which are connected to one another via a sealing surface and together enclose a volume of the housing in a liquid-tight manner At least the first housing part comprises a plastic material and a metallic material enclosed by the plastic material, and the metallic material is arranged so as to be accessible at least in the region of the sealing surface for electrically conductive contacting of the second housing part.

A protective element for improving electromagnetic compatibility. The protective element comprises at least a shielding layer for protection from electric, magnetic, and/or electromagnetic fields.

A system for vibration reducing covers for electrical components. The system includes composite covers for electronic components of drive units to reduce vibrations and associated noise during operation of a vehicle. The cover is formed of a composite to dampen oscillations occurring as a result of vibrations from the drivetrain of the vehicle. The cover also includes a thermal pathway for transferring energy as heat from an interior of compartment containing the electronic components to an environment outside the cover. Additionally, the cover can include an electromagnetic interference and/or radio frequency interference shield to prevent interference with other electronic components on and/or nearby the vehicle during operation.
