Patent number: 8264688Abstract: A method and apparatus for enhancing the accuracy of spectroscopic measurements using a cavity ringdown spectrometer (CRDS) is provided. A first aspect of the invention consists of a novel algorithm for the processing of ring-down data that significantly reduces the amplitude of an exponential fitting artifact, and thereby gives a better estimate of the actual loss. The primary cause of the artifact is the presence of an unwanted backwards-traveling wave that counter-propagates within the ringdown cavity. Scattering due to small imperfections at the cavity mirrors produces this wave and its intensity may be minimized by adjustment of the mirror positions during cavity construction. A second aspect of the invention consists of an apparatus for measuring the backscattered wave within a cavity to allow such cavity mirror adjustments to be made.Type: GrantFiled: November 25, 2009Date of Patent: September 11, 2012Assignee: Picarro, Inc.Inventor: Sze Tan

Patent number: 8232531Abstract: Improved corrosion resistance for direct X-ray imaging detectors is obtained by providing a pixelated, electrically conductive barrier layer between the X-ray sensitive material and the pixel electrodes. Each barrier layer can cover part or all of its corresponding pixel electrode. In cases where pixel electrodes makes contact to underlying circuitry through vertical vias, it is preferred for the barrier layers to cover the via sections of the pixel electrodes. The barrier layers for each pixel electrode can be spaced apart from each other, or they can all be included within a continuous film on top of the pixel electrodes. Such a continuous film can be pixelated by spatially modulating its properties (e.g., thickness, doping) to significantly reduce lateral conductivity from pixel to pixel.Type: GrantFiled: March 29, 2007Date of Patent: July 31, 2012Assignees: Varian Medical Systems, Inc., dpiX, LLCInventors: George Zentai, Larry Partain, William Wei-Yu Yao, Richard Weisfield

Patent number: 8229070Abstract: An adaptive imaging method of monitoring intrafraction target motion during radiation therapy is provided that includes using a simultaneous Mega-Voltage (MV) imaging process and Kilo-Voltage (KV) imaging process to determine an initial 3D target position. 2D target position is monitored using the MV imaging process during a radiation therapy treatment delivery, and is in combination with an online-updated characterization of target motion that are disposed to estimate if the target has moved beyond a 3D threshold distance. The simultaneous MV imaging and KV imaging processes are for accurately determining a new 3D target position for intrafraction motion compensation and for further 2D imaging by the MV imaging process, where another simultaneous MV and KV imaging process is initiated when the target has potentially moved beyond the threshold distance as measured by the MV imaging process. The intrafraction target motion monitoring is achieved at the cost of ultralow patient imaging dose.Type: GrantFiled: September 22, 2010Date of Patent: July 24, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Wu Liu, Lei Xing, Gary Luxton

Patent number: 8196217Abstract: Transmission efficiency and/or spatial resolution provided by resonant apertures can be enhanced by disposing a tip on part of the screen that extends laterally into the aperture. For example, a tip disposed on the ridge of a C-shaped aperture can dramatically improve performance. A spatial resolution of ?/50 has been experimentally demonstrated with this approach. The combination of high spatial resolution and high transmission efficiency provided by this approach enables many applications, such as near field optical probes for near field scanning optical microscopy (NSOM). Another application is high resolution electron sources, where an photoelectron emitter can be disposed at or near a tip+aperture structure such that the high resolution optical near-field provides a correspondingly high resolution electron source.Type: GrantFiled: August 16, 2010Date of Patent: June 5, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yao-Te Cheng, Yin Yuen, Paul C.

Patent number: 8181544Abstract: Preparation methods for introducing liquid samples to gas analysis instruments include 1) complete evaporation of a liquid sample in a sample chamber, and 2) allowing the sample vapor in the sample chamber to equilibrate for a predetermined time. An inert carrier gas (e.g., dry nitrogen or zero air) is also admitted to the sample chamber. After equilibration, the sample vapor is admitted as a conditioned sample to an analysis instrument. Preferably, the predetermined equilibration time is sufficiently long that the sample vapor in the sample chamber becomes substantially homogeneous with respect to both concentration and isotopic ratio. Vapor derived from a liquid calibration standard in this manner can be employed as an accurate gas-phase calibration reference.Type: GrantFiled: November 18, 2008Date of Patent: May 22, 2012Assignees: Picarro, Inc., The Regents of the University of ColoradoInventors: Eric Crosson, Bruce A.

Patent number: 8166385Abstract: A spreadsheet system stores objects and formulas in the cells of the spreadsheet, along with metadata tags. Each cell may contain multiple objects (such as a group of photos). Drag-and-drop user actions automatically change tags associated with the moved objects based on a formula stored in the target cell if a forcing semantics mode is active, or automatically change a formula stored in the target cell if a non-forcing semantics mode is active. A formula in a cell selects a set of objects and may include set operators such as union, intersection, and minus. The formula may also filter sets to select a subset based on specified tag attributes of objects. The display of the spreadsheet adaptively selects a subset of objects to render in a cell and appropriately scales photos for optimal viewing.Type: GrantFiled: August 26, 2009Date of Patent: April 24, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Hector Garcia-Molina, Sean Kandel, Andreas Paepcke, Martin Theobald, Eric S.
