A helmet (20) comprising a mechanism (28) to increase or decrease the internal volume thereof through the displacement of one or more portions (32) of the protective material (24) lining the helmet shell (22). The adjustment mechanism (28) is mounted on or adjacent the shell (22) of the helmet (20), from which project one or more connectors (30) which are operationally connected to the movable portions (32) of the protective material (24). When the adjustment mechanism (28) is activated, for example clockwise or counterclockwise, the connectors (30) are displaced, which causes the movable portions (32) of the protective material (24) to either be displaced away from the shell (22) of the helmet (20) or towards the shell (22) of the helmet (20) and thus allowing for a fine tuning of the fit of the helmet (20) on a player's head.

The invention discloses a car air conditioning system electronic expansion valve control method. Pre-adjustment value s0 of the valve opening of the electronic expansion valve is determined by the rotating speed of a compressor. Actual degree of superheat Tsh is calculated according to temperature and pressure of refrigerant of an outlet of an evaporator or an inlet of the compressor.
