Latest Patents

Joseph M Crowley, Jr. holds a patent for "Magnetic drive systems and methods for a micromachined fluid ejector." This invention operates by magnetically driving a fluid ejector, utilizing a primary coil and a secondary coil situated within the ejector. The design features a movable piston that ejects fluid through a nozzle hole. The piston is resiliently mounted and biased to return to an at-rest position. When a drive signal is applied, current flows through the primary coil, generating a magnetic field that induces current in the secondary coil. This interaction creates a magnetic force that either pushes the piston toward a faceplate to eject fluid or allows fluid to fill the chamber between the piston and the faceplate. The system is designed to efficiently manage fluid ejection and refilling processes.
