Abstract: A mass air flow meter having smaller overall external dimensions than prior devices to facilitate packaging within the engine compartment of a vehicle. Contributing to this smaller size is the use of an "inside-out" venturi in which the inside diameter of the device body is relatively straight and an airfoil shaped body located in the airflow causes the venturi effect. Advantages of this design include high signal to noise ratio, lower manufacturing costs and reduction of bulk.

Abstract: A leadless current-sensing device for sensing current flowing in a conductor when the device is positioned in the vicinity of the current-carrying conductor. The device has a probe having a set of two current sensors disposed at a preset radial angle alpha ".alpha." in respect to each other. The probe also has a second set of two current sensors also disposed at the same preset radial angle in respect to each other. The first and second sets of current sensors are disposed at a preset radial angle delta ".delta." in respect to each other. The first and second sets of current sensors are also disposed at a preset axial distance "z" in respect to each other. The device includes a voltage processing circuit for processing the four distinct voltage potentials induced in the four current sensors. The processing circuit compares to each other two voltage potentials from either set of current sensors to calculate the orientation angle that each current sensor makes with the conductor.
