20140102358 | METHOD, DIE, AND APPARATUS FOR CRYSTAL GROWTH - An apparatus, die, and method can be used form a ribbon from a melt, where capillaries are relatively short and spacers are relatively long as compared to a die opening. Such a configuration can cause the melt to flow is a transverse direction that is substantially parallel to the solid/liquid interface to help move impurities to desired locations. In a particular embodiment, a crystal ribbon can be formed where defects, such as microvoids and impurities, are at higher concentrations near outer edges of the crystal ribbon. The outer edges can be removed to produce crystal substrates that are substantially free of microvoids and have no or a relatively low concentration of impurities. In another particular embodiment, the transverse flow can also help to increase the crystal growth rate. | 04-17-2014 |

20080261828 | Quantum Dot Template for Fast and Simultaneous Detection of Different Infectious Agents - A method and a device for detecting the presence of a predetermined substance, in which a quantum dot is produced on a substrate. The quantum dot emits a radiation at a predetermined wavelength, and is covered with a surface layer to which the predetermined substance attaches. A deviation of the value of a parameter related to the radiation is produced when the predetermined substance attaches to the surface layer. This deviation can be detected to thereby sense the presence of the predetermined substance. | 10-23-2008 |
20100140482 | Self-Referencing Integrated Biosensor Based on Surface Plasmon Resonance Mediated Luminescence - A sensing device for characterizing a substance by modifying modes of resonance of surface plasmons is described. The sensing device comprises: a photo-emitting substrate layer for generating a luminescence signal; a dielectric adaptive layer applied onto the photo-emitting substrate layer; and a sensing layer applied onto the dielectric adaptive layer, the sensing layer having a sensing surface for coupling with the substance to be characterized. The luminescence signal generates surface plasmons having modes of resonance at the interface of the sensing layer and the substance to be characterized. The substance to be characterized, when coupled to the sensing layer, characteristically modifies the modes of resonance of the surface plasmons. | 06-10-2010 |
20120327406 | APPARATUS AND METHOD FOR CHARACTERIZING AN ELECTROMAGNETIC SIGNAL USING SPECTRAL ANALYSIS - An apparatus for characterizing energy and direction dependence of intensity for an electromagnetic signal uses spectral analysis and has particular application in the field of surface plasmon resonance. An energy dependent filter is located in an imaging space of the signal and separates the signal in an energy dependent manner. A first portion of the signal output from the filter is limited to a predetermined range of narrow energy bands and is directed to a photodetector. The photodetector receives the first signal portion and detects signal intensities across the photodetector surface, each of the signal intensities corresponding to a specific wavevector direction and energy band within the predetermined range. The filter provides said energy dependent selection for each of a plurality of different ranges of energy bands so as to create a three-dimensional dataset indicative of the energy and direction dependence of the signal intensity. | 12-27-2012 |

20120091660 | TARGET IMPACT-POINT SENSING SYSTEM - A target includes multiple segments that are vibrationaly isolated from each other. A vibration sensor is coupled to each segment to provide vibration signatures representative of a segment being impacted by a projectile. | 04-19-2012 |
20120171643 | OPTICAL ALIGNMENT DEVICE FOR A WEAPON SIMULATOR USING AN OPTICAL SIMULATION BEAM - An alignment device is provided for a weapon that generates a simulation beam and an alignment beam that is used to properly align the simulation beam with the weapon's sight. The device can be secured to the weapon during the alignment process, after which it can be removed. The device includes a housing that can be mounted on the weapon so that its optical receiving port intersects both the optical alignment beam generated by the optical transmitter and the sighting axis of the weapon's sight. The optical receiving port includes an optical arrangement for receiving the alignment beam and focusing it on a projection screen located inside the housing. An image of the alignment beam on the projection screen can be viewed through the sight by a user. The alignment beam is parallel to the simulation beam. Thus, by centering the alignment beam in the sight, the alignment beam, and hence the simulation beam, will be properly aligned. | 07-05-2012 |
