Abstract: A system for applying fluid to a ground surface, the system includes (a) a plurality of nozzle valves, (b) a control switch and open and close manifold valves for operating each nozzle valve so that each nozzle valve closes essentially concurrently, and (c) a pair of switching manifolds have for operating each nozzle valve so that each nozzle valve is, selectively, opened or closed independently of each other nozzle valve, provided the opened and close valves have not closed the nozzle valves.

Abstract: A thin film vector magnetometer is configured to produce an output that ves linearly with the component of an externally applied magnetic field in the plane of a thin film chip portion thereof along a predefined sensitivity axis. The sensitivity and linear dynamic range of the thin film vector magnetometer are intimately related to each other through a bias field supplied by a bias magnet portion of the device. The bias field also defines the sensitivity axes of the magnetometer which is orthogonal to the unidirectional bias field supplied by the bias magnet.
