An electrical socket assembly having a socket cover slidably mounted to a socket base over a range of motion. The invention is characterized in that the housing base body is made from plastic material, in particular fiber glass reinforced plastic material and that conductor paths are provided on the plastic material or injected into the plastic material which connect a central electric connection to the at least one magnet body andor to the sensor elements detecting adjustment or motion of the camshaft. Battery power can potentially be saved by limiting uplink transmission for user data at the data service level when uplink transmission is unlikely to be successful. In another embodiment, a deodorizer system comprises: a mesh disposed in a housing and for receiving contaminated gas to be deodorized, nanoparticle titania coating on the mesh, and a UV light source disposed to be in optical communication with the mesh. In either case, the one or more indexes can be used for a wide range of purposes, such as to manage data usage quotas at the one or more production servers, as well as to retrieve data from the backup server based on specific file requests. The rotatable head comprises a clutch having a body enclosing a plurality of bearings circumferentially located around the shank, for gripping the shank.
