20080205479 | Apparatus and Method For Sensing Change In Environmental Conditions - An apparatus for sensing a change in environmental conditions is disclosed. The apparatus includes a coating or a wire between two surfaces that has a mechanical property changed as a result of a change in the environmental conditions. The change in the mechanical property of the coating or wire results in a change in a vibration characteristic of the apparatus, such as the frequency, phase, amplitude or quality factor. The change in the vibration characteristic can be used to determine the change in the environmental condition. | 08-28-2008 |
20120270330 | Hybrid Separation and Detection Device for Chemical Detection and Analysis - The present invention provides a device that makes it possible to perform real-time detection and analysis of BTEX components in real samples using an inexpensive and miniaturized hybrid specific binding-separation device. The device may be used in occupational health and safety applications as well as for toxicological population studies to determine the presence of organic volatile components in an air sample. | 10-25-2012 |
