Title: Procede et dispositif permettant de determiner l'angle entre deux facettes d'un objet transparent
Inventor: VERBEKE JOHAN
IPC: G01N21/87
Filed: 2002-06-05
Abstract: L'invention concerne un procédé et un dispositif permettant de déterminer l'angle entre des facettes (6, 7, 9) d'un objet transparent (1), défini par ces facettes (6, 7, 9). Selon cette invention, un faisceau lumineux incident (15) d'une source lumineuse (22) pénètre dans l'objet (1) selon une orientation déterminée, de sorte que ce faisceau lumineux est réfléchi de façon interne sur une facette (6) à mesurer puis quitte cet objet (1) sous la forme d'un faisceau lumineux sortant (20). L'orientation de ce faisceau lumineux sortant (20) est mesurée et l'orientation de la facette (6) à mesurer est calculée à partir de l'orientation du faisceau lumineux incident (15) et du faisceau lumineux sortant (20) et à partir de la réfraction de ces faisceaux lumineux (15, 20) à la surface de l'objet (1).

Title: Procede permettant de modifier l'impedance de dispositifs a semiconducteurs au moyen d'une source de chaleur focalisee
Inventor: LACOURSE ALAIN
IPC: H01L21/329
Filed: 2003-08-08
Abstract: La présente invention concerne un procédé qui permet d'adapter (c'est-à-dire modifier, changer) l'impédance de composants ou de dispositifs à semiconducteurs au moyen d'une source de chaleur focalisée.  On peut recourir au procédé de l'invention pour régler précisément l'impédance de composants ou dispositifs à semiconducteurs, en modifiant le profil de dopage d'une région à faible concentration en dopant (c'est-à-dire en augmentant la concentration en dopant) par la diffusion de dopants depuis des régions adjacentes possédant une concentration plus élevée en dopant sous l'effet de l'action de fusion d'une source de chaleur focalisée, par exemple un laser.  L'invention concerne en particulier l'utilisation de lasers dans le but de créer des liens et tracés conducteurs sur des circuits là où il n'y en avait pas encore.  L'invention se rapporte encore plus particulièrement à des moyens qui permettent de procéder avantageusement à une modification de l'impédance (c'est-à-dire par ajustage ou réglage) en fonction de l'emplacement d'un ou plusieurs ponts conducteurs sur la longueur d'une région d'écartement entre contacts.

Title: Image skeletonization method
Inventor: DENKER JOHN S
IPC: G06T7/00
Filed: 1989-11-08
Abstract: -A method for improved thinning or skeletonizing handwritten characters or other variable-line-width images. The method scans a template set over the image to be thinned. Each template has a specific arrangement of dark and light pixels. At least one of those templates includes either more than three pixels per row or more than three rows of pixels. An odd number is good choice. Moreover, the templatesare chosen so that each template can unconditionally delete image pixels withoutconsideration of the effect of such deletions on the behavior of the other templates. Thus the templates are independent of each other.

Title: Anti-microbial agent
Inventor: WRENCH ERIC
IPC: C02F1/50
Filed: 1989-12-04
Abstract: A B S T R A C T            Glutaraldehyde is a useful anti-microbial agent,  but is dangerous  and  unpleasant  to  handle  and  is  thermally unstable.   Despite these disadvantages,  it  is specified for  use  against  bacteria  in  cooling  towers  of  air conditioning plants of buildings and to control anaerobic sulphate-reducing bacteria in oil wells.   The invention provides the bisulphitc addition complex of an aldehyde or di-aldehyde,  for use  as  an  anti-microbial  agent.   The complex  is  less  toxic  than  free  glutaraldehyde.    In cooling towers it slowly oxidises to the free di-aldehyde. In  oil  wells,  its  digestion  by  the  sulphate-reducing bacteria releases the free di-aldehyde which controls the bacteria.     In   these   ways,   a   more   economic   and environmentally safer use of anti-microbial additives is likely.

Inventor: EBERLING CHARLES E
IPC: B60T13/66
Filed: 1990-07-06
Abstract: ABSTRACT OF THE DISCLOSURE A fluid pressure braking system for a vehicle having service brakes and spring activated parking brakes includes electropneumatic activators for effecting and holding a limited service brake application while the driver leaves the vehicle to make a route pick-up.  Accordingly, the spring brakes are not used during route pick-ups, thereby increasing the life of the spring actuator since it is not repeatedly cycled.  An electropneumatic interlock automatically effects a parking brake application if the vehicle ignition is switched off while an electropneumatic service actuation is effected.

The relectometer is adapted to precisely measure absorption resulting from the constituents present in body fluids.  The sample to be measured is illuminated by a focused light source at an angle of 45° to its surface.  The light diffusely reflected about the normal to the sample falls on a small round bundle of optical fibers.  At the opposite end of the bundle, the fibers are arranged into a narrow rectangle.  This rectangle forms the entrance slit for a concave holographic diffraction grating. The grating forms images of this entrance slit spectrally separated over a flat field suitable for recording the spectrum on film or on an array of discrete detectors.
