A hydraulic pump with a built-in electric motor wherein an electric motor and a pump unit are arranged in tandem fashion and accommodated within a common housing. In an embodiment, a metadata-driven command processor on a machine sends a request for a booting program and application to an agent. Also described is an associated deformable member and fixing member and associated methods for producing and using the seal system. The path loss of a reference signal transmitted from the first mobile device to its base station is communicated to the gateway, along with a parameter associated with the transmit power level of the interfering signal.
