Title: Optical switch for use with optical fibers
Inventor: KOBAYASHI YUJI
IPC: G02F1/29
Filed: 1990-12-07
Granted: 1997-09-09
Abstract: An optical switch for switching an optical path by changing the refractive index of the circumference of a light coupling region of a directional coupler is disclosed.  Such a change is accomplished by a photochromic compound in the circumferential medium of the light coupling region.  Such a photochromic compound when beamed with light of a specific wavelength undergoes a photochromic reaction which changes the refractive index of the circumferential medium of the light coupling region.  Such a reaction is reversible when beamed with light of another specific wavelength.

Title: Method of producing olefin polymer graft copolymers
Inventor: DENICOLA ANTHONY J JR
IPC: C08F255/00
Filed: 1991-01-07
Granted: 1995-10-24
Abstract: Disclosed is a method of making graft copolymers of olefin polymers by contacting a particulate olefin polymer with a free radical polymerization initiator, e.g., a peroxide, and a vinyl monomer at about from 60° to 125° C while controlling the monomer addition rate so that it does not exceed about 4.5 pph/min, and most preferably does not exceed about 3.0 pph/min, at any monomer feed level.  To prevent polymer degradation, a non-oxidizing environment is maintained throughout the process, and residual free radicals are deactivated, and unreacted initiator is decomposed, before the graft copolymer is exposed to all.

Abstract: A seat belt anchor for detachably mounting a seat belt on a bolt has a shank extending axially from a vehicle body panel and a bolt head projecting in a radial direction from the shank.  The seat belt anchor has an anchor plate connected to a seat belt.  The anchor plate has a keyhole shaped slot including an access portion for receiving the bolt head when the access portion is registered with the bolt head and a retaining portion which is narrower than the bolt head and further from the seat belt than the access portion for receiving the shank of the belt.  The anchor plate is mounted on the bolt when the retaining portion of the keyhole shaped slot is registered with the bolt head.  An axially yieldable spring carried by the anchor plate axially engages the bolt head to urge the anchor plate into engagement with the bolt head.  A spring and a pair of detent bosses carried by the anchor plate engage with the bolt head to retain the anchor plate radially holding the bolt in the retaining portion of the key hole slot.  The anchor plate is detachable from the bolt by depressing the anchor plate axially towards the vehicle body panel as permitted by yielding of the axially yieldable spring to disengage the detent bosses from the bolt head and allow sliding movement of the anchor plate in the radial direction to register the bolt head with the access portion.  This allows the detaching of the bolt head through the access portion.

Title: Gradation correction method and apparatus
Inventor: MARUNO SUSUMU
IPC: G06T5/00
Filed: 1992-09-14
Granted: 1997-10-28
Abstract: In video signal processing a gradation correction apparatus for processing R, G, and B input signals includes a luminance signal conversion device for obtaining the original luminance signal, which is before gamma conversion, from the input signals, and a luminance gamma conversion device for gamma converting the original luminance signal to desired gradation characteristics to obtain a gamma converted luminance signal.  The ratio of the gamma converted luminance signal to the original luminance signal is obtained, and this ratio is multiplied by each of the R, G, and B input signals for obtaining primary gradation-corrected R, G, and B signals. The difference between each of the R, G, and B input signals and the original luminance signal is obtained and the gamma converted luminance signal is added to each of these differences for obtaining secondary gradation-corrected R, G, and B signals.  Final gradation-corrected R, G, B signals are obtained based on the primary and secondary gradation-corrected R, G, and B signals.  The result is a system in which effective brightness adjustment is possible within the dynamic range of the image, without changing its hue or saturation characteristics.

Title: Traitement de l'information pour la comparaison de services de sante
Inventor: PERKINS NANCY A K
IPC: G16H70/60
Filed: 1991-04-23
Granted: 1998-09-15
Abstract: Données sur les services de santé obtenues à partir de bases de données de réclamations de malades en consultation externe ou de malades hospitalisés. Un ordinateur traite les données par rapport à des variables cliniques comprenant l'âge, le sexe, le diagnostic, et incluant, de préférence, la comorbidité et certains actes médicaux prodigués. Les variables sont classées en ordres de complexité clinique. L'étendue des relations systématiques entre les variables classées concernant la complexité clinique est déterminée, principalement par analyse de régression, par rapport aux coûts (et, de préférence, par rapport aux procédures et indices de qualité) des services de santé prodigués à un nombre de patients. Selon le présent procédé, les données disponibles sur les soins de santé des patients sont reliées à chaque patient afin que l'information sur l'état de la santé de chacun des patients puisse systématiquement être reliée aux variables propres à la complexité clinique. La détermination des relations systématiques entre les services rendus et les variables de la complexité clinique permet de comparer les coûts (et également, de préférence, les procédures et les indices de qualité utilisés). Pour que les comparaisons soient significatiivement équivalentes, il suffit de rajuster les données en fonction de la complexité clinique des patients qui reçoivent les services en question. Cela permet une comparaison réaliste de l'efficacité des services de santé de différents fournisseurs.
