Abstract: A system for detecting the air pressure in each wheel and for effecting inflation or deflation in each wheel while the vehicle is operating including a controller (30) and a high pressure reservoir (34) mounted on each wheel. Each controller includes a magnet (45) that is positioned responsive to the pressure in the associated tire and a stationarily mounted solenoid detector (32) senses the position of the magnet and generates a signal which is fed to a data processor (97) for the generation of an output signal to the vehicle operator indicating the pressure in the tire. Additionally, through actuation of the control, a current is passed through a coil (62) on the solenoid detector to actuate the magnet (45) in an individual wheel for opening a valve and allowing air to flow through the tube (39) into the tire for raising the tire pressure, or to allow the exhaust of air to lower the tire pressure.

Means (20, 32, 50, 60, 113) are provided to move and control the motion of the upper and lower carriages. The movement of the upper carriage is slaved to the movement of the lower carriage to allow the fibrous material handling system to dispense the fibrous material to the fiber laying head. The fiber laying head can rotate to provide an extra degree of freedom and can also be independently moved normal to a work surface.
