Patent CA-2239728-A1 (CA)
Inventor: BELSHE ROBERT B
IPC: A61P31/12
Filed: 1996-12-09
Abstract: La présente invention est fondée sur une corrélation existant entre deux lésions atténuatrices, propres à la souche cp45, et des défauts spécifiques présents dans le génome de cp45. Plus précisément, un niveau significatif d'atténuation de cp45, résultant de ses phénotypes sensibles à la température et adaptés au froid, est associé à une mutation du gène L de cp45. On a aussi découvert qu'une deuxième mutation du gène codant pour l'hémagglutinine-neuraminidase (HN) de la souche cp45 constitue une autre mutation atténuatrice. La corrélation existant entre ces deux lésions atténuatrices de cp45 et des gènes spécifiques ouvre la voie à des applications pratiques. On peut ainsi créer à présent des vaccins atténués contre d'autres virus de type 3 de la parainfluenza humaine (HPIV-3) de type sauvage et contre des virus autres que les HPIV-3, en incorporant les gènes mutés L et/ou HN de cp45 au génome d'un virus cible, ou bien on peut exprimer dans cp45 des gènes d'antigènes de surface provenant d'autres virus.

Title: Reality mediator with viewfinder means
Inventor: MANN STEVE
IPC: G02B27/01
Filed: 1998-09-23
Abstract: A novel means and apparatus for a new kind of photography and videography is described. In particular, a weak camera with a viewfinder suitable for long-term use is introduced. The system, in effect, absorbs and quantifies rays of light and processes this quantigraphic information on a small computer system, then the processed information is re-constituted into light rays emerging to reconstruct the virtual image of objects at nearly the same position in space, or at a coordinate transformed position, as viewed by the user of the apparatus. The user of the apparatus becomes, after adaptation, an entity that seeks, without conscious thought or effort, an optimal point of vantage and camera orientation. Because of the user's ability to constantly see the world through the apparatus, which may also function as an image enhancement device, the apparatus behaves as a true extension of the user's mind and body, giving rise to a new genre of documentary video.

IPC: B22D11/16
Filed: 1997-04-02
Abstract: The invention relates to a process in a casting mill for producing continuous castings, in particular continuously cast steel, in which the movement of the casting is determined and modified. The invention is characterised by the following process steps: (a) the melt surface is covered with a casting powder which forms a liquid slag to produce a lubricating film between the casting outer shell and the mould inner wall; (b) a measured value characterising the friction between the casting outer shell and mould inner wall is determined in the oscillation device and forwarded to the evaluation unit (in the form of a computer); (c) the signal which characterises the path-time behaviour of the casting is likewise forwarded to the computer; (d) the computer correlates and links the measured values or signals for the path-time behaviour of the casting and the friction of the casting in the mould to produce comparable values and compares them to a reference value; (e) the reference value is determined as a mean value of the casting speed from the path-time behaviour of the casting; (f) from the discrepancy between actual and reference values, a signal is generated to adjust the casting powder composition in order to reduce friction and/or mould vibration.

Title: Delay compensated doppler radar altimeter
Inventor: RANEY RUSSELL KEITH
IPC: G01S13/90
Filed: 1996-09-30
Abstract: A delay compensated Doppler radar altimeter which elimitates the relative delay curvature associated with the energy reflected by a scatterer (x3, x2, x n) located in the along-track direction of an aerial platform (10) for which a most accurate estimation of scatterer elevation is desired. By Doppler shifting each return, the range indicated for each scatterer over its illumination history is equal to the minimum range x h experienced when the relative velocity between the aerial radar (10) and the ground is effectively zero. Compensating each signal so that its entire along-track history can be used for elevation estimation leads to an advantage of more than 10dB in gain improvement over existing systems, and less degradation from surface topography (13).

Title: Radar-based method of measuring the level of a material in a vessel
Inventor: LALLA ROBERT
IPC: G01S13/10
Filed: 1999-05-05
Abstract: For measuring the level of a material in a vessel by a radar-based method an antenna arranged above the highest level anticipated radiates electromagnetic waves to the surface of the material contained in the vessel and receives reflected echo waves. The transit time of the wanted echo waves reflected by the material surface is measured from which the level is computed. Since this transit time corresponds to the group delay, for determining the reduction factor by which the group velocity of the electromagnetic waves differs from the velocity of propagation in the free space due to the geometry of the propagation space the phase difference of the wanted echo waves relative to a reference oscillation and the group delay are measured for various levels and the reduction factor is determined on the basis of the changes in the phase difference as a function of the group delay.
