A wheelchair restraint has four primary components: a base assembly, two pivot members or arms, hinges and belt assemblies. A bending lever stands on the joystick. The filtered search results are processed to ensure that certain portions of the results are from domains included in the filter. The valve actuation system includes an assembly mounted on the valve stem to rotate the valve member between its open and closed positions. The method may be implemented to provide good polycide adhesion characteristics with reduced process complexity over conventional methods by eliminating the need for additional process steps such as metal silicide encapsulation or polysilicon surface treatments. The apparatus may be fabricated using conventional fabrication processes.
