Patent number: 8128185Abstract: A signal converter that may perform functions to enable a thermally based technology to be used with a piezo-electric printhead. The signal converter and piezo-electric printhead may optionally be used in conjunction with a chassis assembly having an adjustable vertical member for sizing the chassis assembly to a printer. Methods of using a piezo-electric printhead in a printer having a thermal printhead configuration may include the steps of coupling the printhead to the printer and performing conversion functions.Type: GrantFiled: March 24, 2010Date of Patent: March 6, 2012Assignee: MVM Technologies, Inc.Inventors: Daniel W. Loyer, Stephen L. Boden

Patent number: 7946690Abstract: A printhead or other droplet emitter is manufactured integrally with a flexible circuit. Preferred methods of manufacturing a droplet emitter comprise the steps of: creating metal traces, preferably deposited using a metal oxide precursor; patterning a sacrificial photoresist to create ink channels and nozzle chambers; depositing piezoelectrically active material over the metal traces and sacrificial photoresist; patterning vias through the piezo-electrically active material to act as nozzles and openings to ink reservoirs; and flushing out the photoresist. The piezo-electrically active material is preferably a mixture of PZT and PVDF.Type: GrantFiled: February 19, 2008Date of Patent: May 24, 2011Assignee: MVM Technologies, Inc.Inventors: Daniel W. Loyer, Henry Roskos, Bruce Hammond

Patent number: 7871154Abstract: Contemplated printheads include a piezoelectric material in which a channel is formed across the piezoelectric material to thereby create at least part of the nozzle through which ink is expelled from the inside of the printhead to the outside. Contemplated nozzles may be configured as cylindrical elements or ring-shape elements. Consequently, application of a voltage across the piezoelectric channel may result in constriction of the cylindrical element or convex/concave deformation of the ring-shape element. Most preferably, the piezoelectric material, conductive traces, and supporting structures are applied from a liquid phase to a carrier, and shaped using photolithographic methods.Type: GrantFiled: July 26, 2006Date of Patent: January 18, 2011Assignee: MVM Technologies, IncInventor: Daniel W.

Publication number: 20080186337Abstract: Non-OEM printer cartridges for printers expecting an OEM cartridge are presented. A non-OEM printer cartridge includes a medium delivery system other than a medium delivery system ordinarily used or expected by a printer. A circuit within the non-OEM cartridge parasitically draws power from signal lines activated by the printer and powers the non-OEM cartridge's medium delivery system. Additionally, the circuit maintains a power draw and impedance within the printer's tolerance so that the printer accommodates the non-OEM cartridge.Type: ApplicationFiled: January 31, 2008Publication date: August 7, 2008Applicant: MVM Technologies Inc.Inventor: Bruce Hammond
