Patent number: 9730333Abstract: A solution of metal ink is mixed and then printed or dispensed onto the substrate using the dispenser. The film then is dried to eliminate water or solvents. In some cases, a thermal curing step can be introduced subsequent to dispensing the film and prior to the photo-curing step. The substrate and deposited film can be cured using an oven or by placing the substrate on the surface of a heater, such as a hot plate. Following the drying and/or thermal curing step, a laser beam or focused light from the light source is directed onto the surface of the film in a process known as direct writing. The light serves to photo-cure the film such that it has low resistivity.Type: GrantFiled: May 14, 2009Date of Patent: August 8, 2017Assignees: Applied Nanotech Holdings, Inc., Ishihara Chemical Co., Ltd.Inventors: Yunjun Li, David Max Roundhill, Mohshi Yang, Igor Pavlovsky, Richard Lee Fink, Zvi Yaniv

Patent number: 7782462Abstract: Sensing a gas includes introducing a gas into a chamber, forming a standing acoustic wave in the chamber, and irradiating the chamber with electromagnetic radiation. Some of the electromagnetic radiation passes into the chamber, through the standing acoustic wave in the chamber, and out of the chamber. An amount of electromagnetic radiation that passes out of the chamber, or is transmitted through the chamber, is detected. A concentration of the gas in the chamber can be assessed.Type: GrantFiled: November 27, 2007Date of Patent: August 24, 2010Assignee: Applied Nanotech Holdings, Inc.Inventor: Igor Pavlovsky

Patent number: 7728520Abstract: An optoelectronic modulator is based on the concentration of an electron beam from an electron gun by a tapered cavity, which sides are photosensitive and change the electrical conductivity under the illumination of light (electromagnetic radiation). The light modulation causes the corresponding changes in the current transported across the walls of the cavity. The remaining part of the electron current exits the cavity aperture and forms an amplitude-modulated divergent electron beam.Type: GrantFiled: January 14, 2005Date of Patent: June 1, 2010Assignee: Applied Nanotech Holdings, Inc.Inventors: Zvi Yaniv, Igor Pavlovsky, Richard Fink
