A method for lubricating at least one blade pitch bearing of a wind turbine is provided. Wall reduction portions are formed respectively in partition walls of the connector housing, each interposed between the adjacent terminal receiving chambers, so that an impedance of the connector can be matched with an impedance of the cable. In various embodiments, the application firewall processes a received HTTP response to a request by a networked entity serviced by the intermediary device. The stub implementation of the interface class may include a first constructor configured to set the implementation pointer to the stub implementation object. This is performed without penetrating through an exterior wall surface of the shaft.
