20120194901 | EFFICIENT TERAHERTZ SOURCES BASED ON DIFFERENCE-FREQUENCY GENERATION IN TRIPLY-RESONANT PHOTONIC RESONATORS - A system for efficient generation of THz radiation is provided that includes a triply-resonant nonlinear photonic resonator coupled to at least one near-infrared (NIR) or optical waveguide and to at least one THz waveguide. The energy traveling through the at least one near-infrared (NIR) or optical waveguide is converted to THz radiation inside the triply-resonant photonic resonator via a nonlinear difference frequency generation (DFG) process. | 08-02-2012 |
20140017145 | MANIPULATION OF FLUIDS IN THREE-DIMENSIONAL POROUS PHOTONIC STRUCTURES WITH PATTERNED SURFACE PROPERTIES - A three-dimensional porous photonic structure, whose internal pore surfaces can be provided with desired surface properties in a spatially selective manner with arbitrary patterns, and methods for making the same are described. When exposed to a fluid (e.g., via immersion or wicking), the fluid can selectively penetrate the regions of the structure with compatible surface properties. Broad applications, for example in security, encryption and document authentication, as well as in areas such as simple microfluidics and diagnostics, are anticipated. | 01-16-2014 |

20080240948 | DEVICE FOR CONTAINING CATASTROPHIC FAILURE OF A TURBOMOLECULAR PUMP - A device for containing the catastrophic failure of a vacuum pumping system is described. The vacuum pumping system includes a turbo-molecular pump (TMP) configured to be coupled to a vacuum processing system at an inlet end. The TMP includes a longitudinal axis substantially parallel to an axis of rotation of the TMP and a first lateral axis substantially perpendicular to the longitudinal axis. The vacuum system also includes a containment device configured to mitigate the catastrophic failure of the TMP by impeding only one translational degree of freedom (DOF) and only one rotational DOF of the movement of the TMP. Impeding only one translational DOF includes impeding translational motion of the TMP in a first lateral direction substantially parallel to the first lateral axis. Impeding only one rotational DOF includes impeding rotation of the TMP about the longitudinal axis. | 10-02-2008 |

20090267825 | Method and Apparatus for Compressing SAR Signals - A method compresses synthetic aperture radar (SAR) data by sampling the SAR data into blocks and transforming each block to a corresponding block of transform coefficients. Each block of transform coefficient is quantized according to a quantization parameter to obtain a corresponding block of quantized transform coefficients, which are demultiplexed into sets of blocks of quantized transform coefficients. The quantized transform coefficients in the blocks in each set are arithmetically encoding in parallel according to a probability model to produce an intermediate bitstream for each set of blocks. The encoding of the quantized transform coefficients of one block is independent of the quantized transform coefficients of a successive block. The intermediate of bitstreams are then multiplexed to a compressed bitstream, which can be transmitted, or stored, for subsequent decoding to construct an SAR image. | 10-29-2009 |
