| Number | Title | Issue Date |
| 7256393 | Non-linear signal amplifiers and uses thereof in a mass spectrometer device Signal amplifiers having a non-linear transfer function. A high speed (high bandwidth) circuit with a non-linear transfer function over a limited range of input signal is provided. By appropriate choice of components, the non-linear transfer function can be used to ... | 08/14/2007 |
| 6647347 | Phase-shifted data acquisition system and method Improved data acquisition systems and methods that enable large numbers of data samples to be accumulated rapidly with low noise are described. In accordance with this inventive approach, a plurality of data samples is produced from a transient sequence i... | 11/11/2003 |
| 5606167 | Contraband detection apparatus and method A contraband detection system (18) using a single, cone shaped neutron beam determines substances concealed in a sample object by developing total neutron cross section spectra for a plurality of elements, including carbon, nitrogen, oxygen, hydrogen and ... | 02/25/1997 |
| 5440136 | Anisotropic neutron scatter method and apparatus A non-invasive inspection system employs the isotropic, resonant scattering of neutrons from an object to determine the presence of at least one preselected element therein. A monoenergetic neutron beam is impinged onto the object and a first detector is ... | 08/08/1995 |
| 5155366 | Method and apparatus for detecting and discriminating between particles and rays Apparatus and method for detecting a particular type of particle in an energy range of interest are provided. The apparatus includes two photomultipliers (24, 26) which are spaced apart in facing relation to one another. A scintillator (22) is positioned ... | 10/13/1992 |
| 4959548 | Neutron apparatus for measuring strain in composites A method and apparatus for orienting a pulsed neutron source and a multi-angle diffractometer toward a sample of a ceramic-matrix or metal-matrix composite so that the measurement of internal strain (from which stress is calculated) is reduced to uncompli... | 09/25/1990 |
| 4918315 | Neutron scatter method and apparatus for the noninvasive interrogation of objects A system and method for the inspection and/or search for concealed objects impinges a monoenergetic neutron beam upon an object, notes the energy distribution of the neutrons scattered from the object and correlates the energy/intensity distribution of th... | 04/17/1990 |
| 4543230 | Pulsed-neutron monochromator In one aspect, the invention is an improved pulsed-neutron monochromator of the vibrated-crystal type. The monochromator is designed to provide neutron pulses which are characterized both by short duration and high density. A row of neutron-reflecting cry... | 09/24/1985 |
| 4180736 | Use of a large time-compensated scintillation detector in neutron time-of-flight measurements A scintillator for neutron time-of-flight measurements is positioned at a desired angle with respect to the neutron beam, and as a function of the energy thereof, such that the sum of the transit times of the neutrons and photons in the scintillator are s... | 12/25/1979 |
