Title: Sensor for detecting and/or measuring concentration of electric charges contained in an atmosphere, corresponding uses and method for making same
Inventor: MOHAMMED-BRAHIM TAYEB
IPC: G01N27/414
Filed: 2005-07-07
Abstract: L'invention concerne un capteur pour la détection et/ou la mesure d'une concentration de charges électriques contenues dans une ambiance. Le capteur comprend une structure de transistor à effet de champ comprenant un pont (4) qui forme une grille et est suspendu au-dessus d'une couche active (10) située entre des zones de drain (6) et de source (7). Une tension de grille possédant une valeur déterminée est appliquée au pont. Une zone, dite air-gap (9), est comprise entre le pont (4) et la couche active (10) ou une couche isolante (8) déposée sur ladite couche active, et possède une hauteur déterminée. Un champ électrique E, défini comme le rapport entre la tension de grille et la hauteur de l'air-gap, est crée dans l'air-gap. Selon l'invention, le champ électrique créé dans l'air-gap possède une valeur supérieure ou égale à une valeur seuil déterminée (50 000 V/cm, 100 000 V/cm, ou encore préférentiellement 200 000 V/cm), suffisamment importante pour que le champ électrique E influence la distribution de charges électriques contenues dans l'ambiance et présentes dans l'air-gap, et permette l'obtention d'une sensibilité élevée du capteur par une accumulation de charges électriques sur la couche active.
Patent CA-2572713-A1 (CA)
Title: Cerenkov x-ray detector for portal imaging
Inventor: ROWLANDS JOHN A
IPC: G01T1/22
Filed: 2007-01-02
Abstract: The present invention provides a practical design of a megavoltage x--ray detector with both high quantum efficiency (QE) and high resolution.  The x-ray detector includes an optical-fiber taper (OFT) made from a large number of optical fibers, each of which is aligned with the incident x-rays from an x--ray source hitting a top surface of the optical fiber taper. The optical-fiber taper is a matrix of optical fibers with the core material made of, e.g., silica and coated with a cladding glass or polymer such that light created within the core of each optical fiber will be guided to the bottom ends of the fiber with the ends of the fibers at the bottom being optically coupled to and optical image read-out device. Each optical fiber in the optical fiber taper is fully aligned with the incident x-ray source so that x-rays entering the top of the fiber travel directly towards the bottom of the same fiber. This alignment (or focusing) of the optical-fiber taper towards the x-ray source can be achieved by an extra coating at the bottoms of the optical fibers so they have a larger diameter than the other top ends of the fibers.

Inventor: LOVE KAREN M
IPC: A01H1/00
Filed: 2005-05-31
Abstract: A method and apparatus are disclosed for modeling a system to estimate values and associated uncertainties for a first set of variables describing the system. A second set of system variables is selected, where the second set is directly or indirectly causally related to the first set of variables. Data is obtained or estimated for each variable in the second set and the quality of selected data is appraised. A network is formed with nodes including both sets of variables and the quality appraisals, having directional links connecting interdependent nodes, the directional links honoring known causality relationships. A Bayesian Network algorithm is used with the data and quality information to solve the network for the first set of variables and their associated uncertainties.
