Abstract: An apparatus for determining a characteristic, as velocity or direction, of a fluid flow stream. Fluid sensors generate signals which are differentially compared to produce an error signal representative of the amount of movement, for the sensors or for a fluid stream generator, which is necessary to null the system. A servomechanism produces the nulling movement in response to the error signal. The amount of movement also generates a positional signal indicating the low frequency component or steady state characteristic of the fluid flow stream. A signal adder combines the positional signal with the error signal, containing a high frequency component, to provide an indication of the instantaneous fluid characteristic.

Abstract: A method and apparatus for determining the velocity of a fluid flow stream. A fluid jet source is disposed opposite a pair of fluid pressure detectors so that the jet stream equally intersects both detectors when the velocity of the fluid flow stream is zero. Means are provided for relatively laterally displacing the jet with respect to the detectors, and for sensing the pressure difference at the detectors, in order to indicate the velocity of the moving fluid flow stream.

Abstract: A stall warning indicator having no moving parts is mounted on a leading edge of an aircraft wing, near the point of stagnation of airflow when a stall condition occurs. The indicator includes a transmitter emitting transmissions, as a continuous acoustic wave or a jet airstream, which are received by a pair of detectors connected to a differential sensor. When the stagnation point passes the axis of the transmissions, the differential sensor produces a signal to warn of an impending stall.
