With a total of 4 patents to his name, his work has had a considerable impact on the efficiency and functionality of various devices.

Latest Patents

One of his latest patents is a paper feeder that employs a retard roll mounted on a shaft controlled by a magneto rheological variable clutch. The current is adjusted to this clutch to produce a variable drag torque, which ranges from near zero to fully locked. This adjustment is based on various inputs, including media type, temperature, humidity, media size, and transport speed. The variable drag on the retard roll results in a reduction of induced skew of sheets passing through a nip formed between the retard roll and a separation roll, leading to less and more consistent wear of the retard roll.

Another significant patent is the document handler/scan tub skew correction system. This innovation improves a skew adjustment system used for correcting skew between a document handler and a scan tub. It includes curved slots in the base portion of the document handler, which are positioned to rotate over protruding members from the surface of a movable portion of a hinge connecting the document handler to the scan tub. The rotation generates a virtual pivot point that increases the angular adjustment between the scan tub and the document handler while minimizing misalignments.
