An electrical device including an opening in a low-k dielectric material, and a copper including structure present within the opening for transmitting electrical current. The filter elements also contain at least one coupling member enabling connection on the end side of a corresponding support tube to an additional support tube having a location on the end side for interacting with and locking on the coupling member. The device thereby provides a means to acquire the desired leveling pressure readings of the intra-vascular catheter with minimal amount of effort by attaching one end of the filament there to the patient and the opposing end to the transducer. In another embodiment, a method of distributing security policy information from a server to a mobile computing device is disclosed. Having determined which person is speaking, the personal speech recognition parameters for that person are selected and used to convert the sound data to text data. The sintered powder layer is formed on an inside wall of the groove tube, and the groove tube is filled with the working fluid.
