A method and apparatus for accurately registering electronic chip bonding pads with substrate leads. Images are developed of different portions of the interface between the electronic chip and the substrate by reflecting collimated, parallel light from the bottom of the chip through transparent areas of the substrate. Image analysis of the composite, superimposed images from spaced positions containing the bonding pads and the leads provide a corrective positioning after which the electronic chip and substrate are brought into contact.

A system is disclosed for the detection of blood flow. The system provides, a portable transceiver unit having a signal generator, a signal comparator, and an audio output whereby a user receives an audio signal indicating differences in Doppler signal, and a Doppler probe coupled to the portable transceiver. The Doppler probe including a piezoelectric crystal disposed at a first end of the Doppler probe; at least one wire transmitting signals between the transceiver unit to the piezoelectric crystal; a rigid or flexible sheath disposed around at least part of the at least one wire and the piezoelectric crystal; and a transceiver unit coupler disposed at a second end of the Doppler probe. The system may also have a quantitative blood flow meter or signal strength meter.

An apparatus for optically controlling the volume of adhesive extruded from an orifice. A camera continuously monitors the adhesive discharged from the orifice; this adhesive is not applied to the target area until its volume is within preestablished limits. When the volume of adhesive is visually determined to be acceptable it is then applied to the target area. The camera is used again, to confirm the proper amount of adhesive has been applied to the target area by measuring the volume of adhesive remaining on the orifice after contacting the target area.

A dispensing pump includes first and second sleeve assemblies. Each sleeve assembly includes a rotary valve having an input and output position and a longitudinally displaceable piston that moves between a first position abutting the valve and a second position displaced from the valve. The sleeve connects to a manifold with input and output passages that align with input and output apertures in the sleeve. Withdrawing the piston with the input port of the valve aligned with the input aperture draws material into the sleeve. Moving the piston toward the valve in the output position with the output port aligned with the output passage displaces material from the manifold.
