Publication number: 20130066349Abstract: An electronic odor sensor is used in conjunction with a surgical tool, for example when wounds are cleansed to remove dead tissue and exudates, known clinically as debridement. The surgical tool will atomize substrate tissues and thereby mechanically generate vapors that can be sensed. Abrasion will likewise atomize substrate tissues liberating odors. Air near the surgical tool is collected and fed into the electronic odor sensor. The odor is analyzed by the sensor and a signal fed back based on the analysis.Type: ApplicationFiled: September 12, 2012Publication date: March 14, 2013Applicant: Applied Nanotech Holdings, Inc.Inventors: Richard Lee Fink, Zvi Yaniv, Leif Thuesen, Alexei Tikhonski, Royce W.

Publication number: 20130017647Abstract: Described herein is a novel material that easily penetrates silicon nitride-based anti-reflective coatings, forming a high quality electrical contact. A method for metallization on a solar cell includes depositing a passivation layer on a silicon substrate of a solar cell, depositing derivatized metal particles onto the passive layer, heating the substrate of the solar cell to migrate surface coatings from the derivatized metal particles onto the passivation layer creating a diffusion Channel through passivation layer to the silicon substrate, and as the metal particles melt due to the heating on the substrate, the melted metal diffuses through the diffusion channel forming a metallic content with the silicon substrate.Type: ApplicationFiled: July 10, 2012Publication date: January 17, 2013Applicant: APPLIED NANOTECH HOLDINGS, INC.Inventors: James P.

Patent number: 8294116Abstract: Optical beam modulation is accomplished with the aid of a semiconductive nanomembrane, such as a silicon nanomembrane. A photocathode modulates a beam of charged particles that flow between the carbon nanotube emitter and the anode. A light source, or other source of electromagnetic radiation, supplies electromagnetic radiation that modulates the beam of charged particles. The beam of charged particles may be electrons, ions, or other charged particles. The electromagnetic radiation penetrates a silicon dioxide layer to reach the nanomembrane and varies the amount of available charge carriers within the nanomembrane, thereby changing the resistance of the nanomembrane. As the resistance of the nanomembrane changes, the amount of current flowing through the beam may also change.Type: GrantFiled: September 11, 2009Date of Patent: October 23, 2012Assignee: Applied Nanotech Holdings, Inc.Inventors: Nan Jiang, Richard Lee Fink
