Abstract: The present disclosure relates to systems, methods, and devices for headphone speakers. In one embodiment, headphone speaker system is provided including a headset unit and an earphone pair. The headset unit and earphone pair are reconfigurable and module sound emitting units that allow for multiple arrangements, including output of audio signals to both the head set unit and the earphone pair, or selective output of audio to one of the head set unit and earphone pair. The headset unit is configured to include ear cups that allow for mounting the earphone pair in one or more positions. The headset unit can charge the earphone pair. In some embodiments, a headphone system is provided including earphone speakers that may be inserted within ear cups and that operate either independently or combined with headset speakers. Processes and device configurations are provided for selective output of audio to speaker systems and headset unit.

Abstract: The present invention provides shielded printed circuit boards and electronic devices. The printed circuit board may comprise an internal network of grounded conductive elements that are coupleable to an EMI shield that is mounted on the printed circuit board. The network of grounded conductive elements are coupleable to a grounded layer and to the EMI shield and provides improved EMI shielding through the volume of the printed circuit board below an electronic component mounted on the printed circuit board.

Abstract: The present invention includes improved RFID antennae and tags and methods of manufacturing the RFID antennas. The RFID tags of the present invention include a substrate that comprises an antenna assembly. A radiofrequency integrated circuit is in electrical communication with a portion of the antenna assembly. The RFID tag may include a structure, such as a lid element, that clamps and/or compresses the radiofrequency integrated circuit into contact with the antenna assembly, without the need for a conductive adhesive. In some embodiments, the antenna assembly is vacuum metallized or otherwise applied onto the substrate through patterned openings in a mask, such as a patterned masking cliché or a patterned polymer layer.

Abstract: The present invention provides methods and devices for shielding an electronic component package. In one embodiment, an EMI shield is integrally formed within the package adjacent the die and grounded. The EMI shield may be a metallized shaped polymer layer and may be disposed fully within the package or it may extend out of the package.

Abstract: The present invention provides in-line equipment and methods for manufacturing an EMI/RFI shield that is integrated formed in a formable sheet. The EMI/RFI shield may comprise a shaped thermoform shell that has one or more conductive layers applied to one or more surfaces. The EMI/RFI shield may be integrally formed with the formable sheet via attachment tabs that are positioned along one or more edges of the EMI/RFI shield.

Abstract: The present invention provides electromagnetic interference filters and gaskets. In exemplary embodiments, the filters and gaskets are made from conductively coated reticulated foam having a pore density varying from 10 to 40 pores per inch (PPI). The filters can be used to cover ventilation openings in an electronics enclosure to shield electrical components, equipment and devices from EMI, electrostatic discharge (ESD) and radio frequency interference (RFI) while still providing adequate airflow to enter and cool the system. The filter material may also help prevent dust and dirt from entering the enclosure. The filters of the present invention are also well suited to conductively bridge gaps between mating features of electronic enclosures. The reticulated foam to fabricate the filters allow for excellent compression (generally 20%-50% of the original thickness) under low compressive forces, while easily recovering from the compressive load without noticeable compression set (permanent deflection).
