A mobile communication device for communicating a radio communication device associated with a radio transmitter. The low friction piston 18 design reduces drag and provides consistent cleaning fluid 12 pressure. In one embodiment, multiple sheet elements may be arranged to telescope from the back of the notebook computer screen to adjust the size of the copy holder. When the dual-pole blade is inserted in the slot the first contact contacts a respective blade element at a location in the slot more proximate the slot busbar end than a slot distal end. This results in an homogeneous -microstructure of the isothermal solidified, brazed joint with mechanical properties similar to those of the base material.
