Title: Innovations of John R. Rosenberger

Introduction

John R. Rosenberger is an accomplished inventor based in Centerport, NY (US). He holds three patents that showcase his innovative contributions to technology. His work primarily focuses on advancements in inkjet printing and wind-powered vessels.

Latest Patents

One of his latest patents is for "Fast drying ink jet ink compositions for capping ink jet printer nozzles." This invention provides methods and apparatus for preventing clogging in impulse inkjet printers. It has been discovered that ink clogging during quiescent periods can be mitigated by using an ink that forms a barrier of higher viscosity where it contacts the ambient air. This viscous barrier protects the remaining ink from air exposure during idle periods. The barrier can be removed through a series of sub-pulses that re-homogenize the viscosity barrier and clear the nozzle.

Another significant patent is for a "Configurable wind powered vessel." This design features four spars that project downward and outward from a common juncture, with a mast extending upward from the same point. Adjustable cables interconnect the distal ends, creating a uniquely strong and lightweight pentahedral-shaped space frame. The innovative cable length adjustment system allows for reconfiguration of the vessel's geometry while underway. This adaptability enables the vessel to be tall and narrow for easier maneuvering in light winds or broad and low for maximum capsize resistance. The design includes two hulls that can split into four planing shapes when sufficient propulsion force is present.
