Patent CA-2046314-A1 (CA)
Title: Contraband detection system using direct imaging pulsed fast neutrons
Inventor: SAWA Z PETER
IPC: G01N23/222
Filed: 1991-01-09
Abstract: A system and method for detecting contraband generates a highly collimated beam (13) of pulsed fast neutrons, having a pulse width on the order of a nanosecond, and an energy of 5 to 9 MeV. An object (14) under investigation is scanned with the collimated pulsed beam. The neutrons in the beam cause (n, .gamma.) reactions in a limited object volume or voxel, defined by the inter-section of the collimated beam and the scanned object. The highly penetrating fast neutrons produce nuclear reactions with the atomic elements present within the object, causing gamma rays to be emitted.  The gamma rays are detected in a gamma ray detec-tor (20). The approximate time of flight of the neutron pulse is measured, allowing a determination to be made as to the particular voxel from which the gamma ray originated. The energy of the detected gamma rays identifies the particular elements from which the gamma rays originated. Thus, e.g., the carbon, nitrogen, oxygen, and chlorine content, which elements are commonly found in contraband, of a particular voxel can be determined directly and precisely.  The voxel content information may be combined from a substantial sample of the voxels that make up the object to provide a direct indication of the elemental content of the object, and hence whether contraband is present or absent within the object.

Title: Multi-sensor explosive detection system
Inventor: GOZANI TSAHI
IPC: G01V5/00
Filed: 1990-06-15
Abstract: A nuclear detection system (100) and method efficiently detects contraband, such as explosives, in checked airline baggage or other ob-jects with a high probability of detec-tion (PD) and a low probability of false alarms (PFD). The detection sys-tem includes a source of thermal neu-trons (102, 130); an array of gamma ray detectors (114, 144); a neutron de-tector (146); means for irradiating the object (136, 142,144) being examined to neutrons from the neutron source which neutrons interact with the at-omic nuclei of one more specific elements, e.g., nitrogen, chlorine, or hydrogen present within the object so as to cause elemental-specific gamma rays to be emitted and processing means (116, 154). Elemental-specific gamma rays detect-ed and counted by the gamma ray detectors and processing means allow the approximate origin of the gamma rays within the ob-ject to be determined, thereby providing a rough measure of the density distribution of these specific elements within the object. Neutrons that pass through the object without substantially interacting with atomic nuclei are detected by the neutron detector, thereby providing an image of the atomic density distribution of the object similar to conventional neutron radiography. One em-bodiment of the invention includes an artificial neural system (ANS) for analyzing the recorded gamma rays and efficiently dis-criminating between objects carrying explosives and objects not carrying explosives. Another embodiment utilizes a spectral correlation method (SCM) to remove undesirable background noise from the spectrum of detected gamma rays. Still another em-bodiment uses an X-ray system ( 150) to generate an electron density image of the object being investigated, which electron densi-ty image helps confirm the presence of explosives within the object.

Abstract: ABSTRACT OF THE DISCLOSURE Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance.          Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener.  Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability.  Control of incorporated air bubbles functions to provide the product with a bulk density of 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase.          Stearic acid or other fatty acid or salt further improved physical stability.

Abstract: PRECIS DE L'INVENTION "ROUE-SECURE"          Un autobus scolaire qui dépose un enfant écolier du coté opposé où il demeure, risque en démarrant, d'écraser cet enfant, si celui-ci décide au même moment, en croyant à l'immobilité de l'autobus, de traverser hâtivement la rue.          La probabilité est telle que cet enfant sera fatalement blessé par l'une des puissantes roues de l'autobus. Une telle tragédie est révoltante, d'autant plus qu'elle ne peut pas être justifiée face au niveau de technologie actuel qui, malheureusement, répond plus efficacement et beaucoup plus vite aux besoins de consommation que de prévention.          Dans la présente invention "ROUE-SECURE", chacune des roues de l'autobus est munie d'une enveloppe métallique semi-circulaire tournant autour de l'axe de la roue par l'entremise d'un système de roulement à billes fixé sur les boulons supportant la jante de la roue.          Cette enveloppe de roue est normalement maintenue dans une position parallèle à l'autobus,  grâce à un mécanisme constitué de deux ressorts fixés sur  le système de pivot de  la roue,  d'un fil flexible métallique attaché à ses extrémités aux-dits ressorts et, attaché à son milieu, à un point d'un electro-aimant de forme circulaire pouvant tourner bi-directionellement de 45 degrés.          Cet électro-aimant, monté dans une boîte métallique vissée à la-dite enveloppe de roue, est commandé via un câble électrique relié à  un  coffret  de  commande  installé  près  du  chauffeur.  Trois commandes sont prévues:  La commande "NEUTRE" pour une position normale de l'électro-aimant soit la position zéro degré, puis la commande  "AVANT",  pour  une  position  +45  degrés  entraînant l'enveloppe de roue vers une position inclinée empêchant la roue de rouler sur l'enfant lorsque l'autobus avance et, enfin, la commande "ARRIERE", pour une position -45 degrés entraînant l'enveloppe de roue vers une position inclinée (symétrique à celle de la commande "AVANT") empêchant la roue de rouler sur l'enfant lorsque l'autobus recule.          Le coffret de commande, alimenté par la batterie de l'autobus, informe continuellement le chauffeur de la position des enveloppes de roues, au moyen de trois lampes témoins.  Le chauffeur peut choisir entre deux modes de fonctionnement: le mode manuel et le mode automatique, grâce à un dispositif de sélection "AUTO-MANUEL". Un voyant lumineux rouge clignotant s'amorce lorsque le chauffeur opte pour le mode manuel.          En mode manuel,  le chauffeur choisit  la position qu'il désire donner aux enveloppes des roues, grâce à un dispositif de sélection "AVANT-NEUTRE-ARRIERE".          En mode automatique, lorsque la porte de l'autobus l'ouvre et la vitesse de l'autobus est raisonnablement basse,  le coffret de commande envoie le signal de commande "AVANT" et, dans le cas contraire, le signal de commande "NEUTRE".

Abstract: Described is a circuit arrangement for dynamic control of a voice terminal apparatus which contains a compander function. Instead of analog circuits for dynamic expander and compressor, a digital signal processor (DSP) is employed which, via a prestored characteristic (KL), assigns to individual average level values of the input signal, amplification factors which are fed to the amplifier (VS) located in the send path of the terminal apparatus. The stored characteristic can be shifted or replaced by another characteristic as a function of a noise average value, or from a receive average value obtained from the audible feedback signal. Thus, an amplification change in the send path is compensated in its action upon the audible feedback signal arriving via the receive path.   In a further development, the circuits delivering the level average values are replaced by the digital signal processor, which carries out the functions assigned to these circuits by means of subprograms.
