The present invention relates to a filter and a method of manufacturing the same, the filter including an RF connector configured to have a predetermined electrical signal line, a filter body having at least one impedance matching space in which the RF connector is installed, a relevant PCB on which one end of the RF connector is fixedly mounted, the relevant PCB coupled to be in close contact with one side surface of the filter body, and an annular gasket interposed between one side surface of the filter body and the relevant PCB to block a signal leak, in which a concave-convex portion is processed on a surface of one side surface of the filter body to which the annular gasket is attached to increase an attachment area, thereby providing an advantage of improving a bonding force of an attachment portion to which the gasket is attached.

A modular system of plastic walls having embedded and coextensive electrically conductive components configured to electrically connect with each other when the walls are mated. The walls have joining edges that form joint seams with other walls when joined together to create an enclosure. When enough walls are used to surround a storage space, a Faraday cage is created. The walls additionally have portions of tortuous paths at each joining edge that mate with a complementary portion of a tortuous path of another wall when the walls are joined together. A torturous path seal is thereby created at each joint seam. The plastic walls can be configured in a multiplicity of combinations to create various enclosures necessary for RFID-enabled storage and tracking of medical articles. Containers, enclosures, cabinets, and drawers of differing heights and sizes can be made and they may be stacked or otherwise assembled.

A junction box used for making electrical connections to a photovoltaic panel. The junction box has two chambers including a first chamber and a second chamber and a wall common to and separating both chambers. The wall may be adapted to have an electrical connection therethrough. The two lids are adapted to seal respectively the two chambers. The two lids are on opposite sides of the junction box relative to the photovoltaic panel. The two lids may be attachable using different sealing processes to a different level of hermeticity. The first chamber may be adapted to receive a circuit board for electrical power conversion. The junction box may include supports for mounting a printed circuit board in the first chamber. The second chamber is configured for electrical connection to the photovoltaic panel. A metal heat sink may be bonded inside the first chamber.
