With a total of five patents to his name, Heffelfinger is recognized for his innovative solutions that enhance the performance of disk drive head suspensions.

Latest Patents

Among his latest patents is an Apparatus for insulating and electronically connecting piezoelectric motor in dual stage actuator suspension from the same side of the suspension. This invention describes a method for selectively applying a voltage to one major surface of a dual set of piezoelectric motors (PZTs) on a disk drive head suspension. The design ensures that the primary plane of the load beam is kept parallel to the major surfaces of the PZT elements, which are electrically insulated from the load beam itself. Heffelfinger's innovation allows for electrical connections via various means including wires, solder, and conductive epoxy, or the mechanical attachment of a plated surface of the PZT to a bond pad on an electrically isolated substrate. Lead extensions or separate components can be utilized to connect to the PZTs, which can be installed in the head suspension either on the load beam's major surface or as part of a pre-fabricated motor assembly. Crucial apertures within the load beam and accompanying structures facilitate the physical installation and electrical connectivity of the PZT motors.
