  • Patent number: 8264688
    Abstract: 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.

  • Patent number: 8253946
    Abstract: A sensor includes a sensor head with at least two surfaces separated by a gap. One surface is mechanically fixed, a second surface is free to move and deflections of the second surface relative to the first surface are monitored by optical interferometry. An optical fiber could be used to direct light from a light source to the sensor and collect light reflected by the sensor. Interaction of molecules or other objects in the sample with the second surface is detected as a change in amplitude and/or phase of deflection the second surface in response to an applied driving signal. A layer of binding molecules may be immobilized on the second surface and this surface exposed to a sample.

  • Patent number: 8232531
    Abstract: 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.

  • Patent number: 8229070
    Abstract: 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.

  • Patent number: 8200593
    Abstract: A neural network simulation represents components of neurons by finite state machines, called sectors, implemented using look-up tables. Each sector has an internal state represented by a compressed history of data input to the sector and is factorized into distinct historical time intervals of the data input. The compressed history of data input to the sector may be computed by compressing the data input to the sector during a time interval, storing the compressed history of data input to the sector in memory, and computing from the stored compressed history of data input to the sector the data output from the sector.

  • Patent number: 8196217
    Abstract: 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.

  • Patent number: 8181544
    Abstract: 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.

  • Patent number: 8180714
    Abstract: An automated method for the generation of (i) human models comprehensive of shape and joint centers information and/or (ii) subject specific models from multiple video streams is provided. To achieve these objectives, a kinematic model is learnt space from a training data set. The training data set includes kinematic models associated with corresponding morphological models. A shape model is identified as well as one or more poses of the subject. The learnt kinematic model space and the identified shape model are combined to generate a full body model of the subject starting from as few as one-static pose. Further, to generate a full body model of an arbitrary human subject, the learnt kinematic model space and the identified shape model are combined using a parameter set. The invention is applicable for fully automatic markerless motion capture and generation of complete human models.

  • Patent number: 8166385
    Abstract: 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.

  • Patent number: 8163338
    Abstract: A method of precursor selection for thin film deposition is provided, that includes a group of precursors, using a rule-set for selecting one or more candidate precursors for thermal stability, high growth rate, and low contamination. Candidate geometries and constituent geometries are simulated and optimized, and bond strengths of the candidates and constituents are determined. The rule-set is based on bond strength that compares molecule and constituent energies between a set of bond strengths within a candidate ligand or between a metal atom and one ligand. The rule-set requires metal atom-ligand bonds are between 0.2 and 3 eV, metal atom-ligand bond strengths are less than metal atom-ligand bond strengths of other candidates. The metal atom-ligand bond strength is >T?S, where T is a reaction temperature and ?S is the reaction entropy change and the bond within a ligand, where (ligand bond)>(metal atom and ligand bond).
