The CAD model for a design to be printed is received by a 3D printer. Instructions are generated for printing the first slice. While the instructions are used to start printing the CAD model, dynamic real-time slicing is performed on a remaining portion of the CAD model. Preprocessed data, model analysis information or real-time feedback is received during the printing of a respective slice. A next slice is identified, and slicing parameters are adjusted, including adjusting a slicing parameter for the next slice. Instructions for printing the next slice are generated. The next slice is printed based on the generated instructions. Dynamic real-time slicing is repeated to generate a then next slice and associated printing instructions. | 11-19-2015 |

20090294276 | METHOD AND APPARATUS OF FORMING DOMAIN INVERSION STRUCTURES IN A NONLINEAR FERROELECTRIC SUBSTRATE - A crystal poling apparatus has as ingle-domain ferroelectric substrate (e.g. MgO doped LiNbO3 substrate), a sample holder, a high voltage source, a corona torch, a gas source, a chamber, and at least one vacuum pump. An electrode with a certain structure (e.g. a periodical pattern) is formed on the first surface of the substrate, and the substrate is set with the electrode facing down on top of the sample holder. The electrode is grounded so that high electric field is formed in the area with electrode due to the formation of charges generated by the corona torch on the second surface of the substrate. The charge distribution on the second surface of the substrate is controlled by the high voltage source and the gas source. To achieve the optimized crystal poling, the temperature of the substrate is set by the temperature controller, and the electrode on the first surface of the substrate is isolated by the vacuum pump. | 12-03-2009 |

The two waveforms are measured from the subject. A system is defined that relates the proximal arterial waveform to the distal arterial waveform (or vice versa) in terms of the unknown parameters of a parametric mathematical model. The model parameters are determined from the measured waveforms using system identification. PTT between the proximal and distal arterial sites is then determined from the system model. PWV may also be determined by dividing the distance between measurement sites (D) by PTT. | 07-18-2013 |

20100290037 | PRISM COUPLED SILICON ON INSULATOR SENSOR - Methods and devices related to a sensor element for use in the detection and monitoring of molecular interactions. The sensor element uses a silicon-on-insulator wafer optically coupled to a silicon prism. The wafer has a thin silicon film top layer, a silicon substrate layer, and a buried silicon dioxide layer sandwiched between the silicon film and substrate layers. The wafer is coupled to the prism on the wafer's substrate side while the interactions to be monitored are placed on the wafer's silicon film side. An incident beam is directed at the prism and the incident angle is adjusted until the beam optically couples to the silicon film's optical waveguide mode. When this occurs, a decrease in the intensity of the reflected beam can be detected. The molecular interactions affect the phase velocity or wave vector of the propagating mode. Similarly, instead of measuring the incident angle at which optical coupling occurs, the phase of the reflected beam may be measured. | 11-18-2010 |

Molecular interactions occurring on this surface affect the intensity or the phase of the light beam travelling through the waveguide by changing the effective refractive index of the medium. By measuring the effect on the intensity, phase, or speed of the light beam, the molecular interactions can be detected and monitored in real time. Various configurations using this sensor technology is also disclosed. | 07-01-2010 |

20130159324 | Multi-Source Multi-Step Search in Enterprise Software Systems - A search query is received that is associated with two or more data sources so that a source-specific query is generated for each data source using a data source definition associated with the corresponding data source and the search query. Thereafter, searches are executed for a first set of data sources using the corresponding source-specific queries. These search results from the first set of data sources are consolidated. In addition, searches are executed for a second set of data sources using the corresponding source-specific queries. These search results from the second set of data sources are then consolidated with the consolidated search results from the first set of data sources. In some implementations, at least one search comprises a main search followed by a sub-search that filters results from the main search.

20090080326 | RSVP-TE enhancement for MPLS-FRR bandwidth optimization - RSVP-TE Enhancement for MPLS-FRR Bandwidth Optimization is a method of RSVP-TE protocol enhancement for optimizing network resources when FRR is protecting LSP traffic in a topology where the bypass LSP tunnel traverses the original previous hop(s) of the protected LSP. The node providing FRR protection, the PLR, will use the enhanced message TLVs to report to the nodes all the way back to the HE node. The node(s) on the original path prior to the PLR node can check if there is a better alternative bypass tunnel to use to provide FRR from a network resource optimization perspective (such as using the bypass tunnel from the HE node in a ring topology to reduce the traffic in the ring). | 03-26-2009 |
