| 20090086214 | ALIGNED EMBOSSED DIAPHRAGM BASED FIBER OPTIC SENSOR - The present invention is a diaphragm-fiber optic sensor (DFOS), interferometric sensor. This DFOS is based on the principles of Fabry-Perot and Michelson/Mach-Zehnder. The sensor is low cost and is designed with high efficiency, reliability, and Q-point stability, fabricated using MEMS (micro mechanic-electrical system) technology, and has demonstrated excellent performance. A DFOS according to the invention includes a cavity between two surfaces: a diaphragm made of silicon or other material with a rigid body (or boss) at the center and clamped along its edge, and the endface of a single mode optic fiber. By utilizing MEMS technology, the gap width between the diaphragm and the fiber endface is made accurately, ranging from 1 micron to 10 microns. To stabilize the Q-point of the DFOS when in use as an acoustic sensor, a system of microchannels is built in the structure of the diaphragm so that the pressure difference on two sides of the diaphragm is kept a constant, independent of the hydraulic pressure and/or low frequency noise when the device is inserted in liquid mediums. | 04-02-2009 |

| 20090045061 | Nanotube Devices and Vertical Field Effect Transistors - A method of depositing nanotubes in a region defined by an aperture is disclosed. The method provides advantageous control over the number of nanotubes to be deposited, as well as the pattern and spacing of nanotubes. Electrophoretic deposition, along with proper configuration of the aperture, allows at least one nanotube to be deposited in a target region with nanometer scale precision. Pre-sorting of nanotubes, e.g., according to their geometries or other properties, may be used in conjunction with embodiments of the invention to facilitate fabrication of devices with specific performance requirements. The method is useful for many applications where it is desirable to deposit more than one nanotube in a defined region. For example, vertical field effect transistor (VFET) designs may benefit from having more than one nanotube forming a channel to allow more current to flow through the device. By controlling the number of nanotubes to be deposited, one can ensure that the VFET output can be designed with sufficient current to meet the parameters of a logic circuit input. | 02-19-2009 |
