Publication number: 20140130573Abstract: Methods and apparatuses for detecting moisture are disclosed. Embodiments detect the existence and/or level of moisture in electronic devices, such as by using one or more moisture sensors that removably connect to a pre-existing port in the electronic device (such as a headphone jack or similar port). Some embodiments detect a component of the ambient air (such as moisture level) to improve the accuracy of the moisture detector. Some embodiments decrease pressure at the port using a pneumatic pump and move gas from the electronic device into the moisture detector. Some embodiments detect the movement of air in the vicinity of at least one moisture sensor (such as by measuring pressure) and use this information to improve the accuracy of the moisture detector. Some embodiments display information related to the moisture in the electronic device and/or the ambient air.Type: ApplicationFiled: November 14, 2013Publication date: May 15, 2014Applicant: Revive Electronics, LLCInventors: Reuben Quincey Zielinski, Joel Christopher Trusty, Micah Neil Trusty

Patent number: 8671741Abstract: A moisture content sensing system is described comprising a collar mechanically coupled with a clean grain transport system. An extendable support extends through the collar and has an extendable capacitive sensor element disposed at one end. The extendable support is configured to be located at a first position in which the extendable capacitive sensor element is disposed adjacent to clean grain conveyed by the clean grain transport system and moved to a second position wherein the extendable capacitive sensor element is disposed at least partially within the clean grain of the clean grain transport system.Type: GrantFiled: June 29, 2011Date of Patent: March 18, 2014Assignee: Trimble Navigation LimitedInventors: Michael Cash, D'Anne Beukelaur Hanks, Arthur F. Lange, Brian Jackman, Brian A. Jackson

Patent number: 8673649Abstract: A wireless chemical sensor includes an electrical conductor and a material separated therefrom by an electric insulator. The electrical conductor is an unconnected open-circuit shaped for storage of an electric field and a magnetic field. In the presence of a time-varying magnetic field, the first electrical conductor resonates to generate harmonic electric and magnetic field responses. The material is positioned at a location lying within at least one of the electric and magnetic field responses so-generated. The material changes in electrical conductivity in the presence of a chemical-of-interest.Type: GrantFiled: May 11, 2009Date of Patent: March 18, 2014Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Stanley E. Woodard, Donald M. Oglesby, Bryant Douglas Taylor

Patent number: 8656755Abstract: A measuring device for detecting the amount of moisture in and the temperature of a flowing medium is disclosed. Flow-directing elements which mix the flowing medium and direct it in a desired direction are arranged in the measuring device. The average temperature of the medium can thus be detected using a suitably arranged temperature sensor. In addition, the moisture sensor may be arranged in such a manner that a selective amount of moisture in the medium is detected.Type: GrantFiled: September 7, 2010Date of Patent: February 25, 2014Assignee: EPCOS AGInventors: Benjamin Bohl, Peter Balzer

Patent number: 8646311Abstract: A sensor for detecting hydrogen or ammonia gas uses a gas sensitive material based on Cr2O3 with a small percentage of the chromium replaced by transition metal ions having a valency greater than four, but still having a corundum crystal structure. Electrodes in contact with the gas sensitive material are connected by conductors to electrical measuring means for measuring the resistance, conductance, capacitance, or impedance of the gas sensitive material. A temperature sensing means and heating means allow the temperature of the gas sensitive material to be regulated. The gas sensitive material is formed on an insulator substrate over one or both electrodes. One electrode can be on the non-substrate side of the gas sensitive material. The gas sensitive material can be formed by deposition from a suspension or colloidal dispersion and firing. The gas sensitive material is contacted with gas and changes in electrical properties of the material are observed.Type: GrantFiled: October 31, 2008Date of Patent: February 11, 2014Assignee: Atmospheric Sensors Ltd.Inventor: Patrick T.
