Title: Computer-aided surgery apparatus
Inventor: RAAB SIMON
IPC: A61B34/20
Filed: 1988-02-01
Granted: 1995-07-25
Abstract: To aid a medical practitioner in positioning a surgical instrument or implant when performing surgery on or examining portions of a patient, patient data is developed which identifies the position and orientation of the portion to which  surgical  procedures  or  examinations  are  to  be applied.  The position and orientation of the instrument or implant is sensed and instrument data is developed from this sensing.  The patient data is converted to objective signals to be displayed on a video display, and the instrument data is  converted  to  instrument  signals  for  presenting  the position and orientation of the instrument or implant on the same display.   Thus, by watching the display, the medical practitioner  is  aided in manipulating  the  instrument  or implant relative to the portion.

Abstract: There is disclosed a speech recognition system and technique which is of the acoustic/phonetic type. It is made speaker-independent and capable of continuous speech recognition during fluent discourse by a combination of techniques which include, inter alia, using a so-called continuously-variable-duration hidden Markov model in identifying word segments and making all steps of the technique responsive to the durational information, and using a separate step for aligning the members of the candidate word arrays with the acoustic feature signals representative of the corresponding portion of the utterance, including using pairs of candidate phonetic segments in the alignment technique.Any residual word selection ambiguities are then more readily resolved than in the prior art, regardless of the ultimate sentence selection technique employed.

IPC: A01K91/06
Filed: 1988-03-15
Granted: 1991-09-03
Abstract: Accessoire de pêche destiné à prévenir la rupture du fil à l'extrémité duquel se débat un poisson. L'accessoire comprend un cylindre creux dans lequel coulisse un piston. Le piston porte sur une de ses faces une tige dont l'extrémité libre, en forme d'anneau de fixation, sort du cylindre. Sur l'autre face est disposée une paire de mâchoires venant enserrer la collerette d'une goupille de retenue solidaire de la face intérieure du fond du cylindre. L'autre face du fond porte un autre anneau de fixation. Un ressort est en outre placé sur la tige de manière à prendre appui sur le cylindre et le piston. L'utilisation de l'accessoire de pêche nécessite la coupure du fil et la fixation des deux extrémités aux deux anneaux. Lorsque les mâchoires enserrent la collerette, le piston et le cylindre forment un ensemble rigide permettant de ferrer le poisson comme si le fil était d'un seul tenant. Une fois pris, le poisson, en se débattant, entraîne le dégagement des mâchoires de la collerette et la mise en action du ressort dont l'élasticité permet d'atténuer les sollicitations que subit le fil.

Filed: 1988-03-28
Granted: 1991-07-16
Abstract: METHOD FOR FORMING PATTERNED TIN OXIDE           THIN FILM ELEMENT          Abstract of the Disclosure A method is disclosed for forming a semiconductor tin oxide thin film on a selected region of a surface without forming the film on an adjacent region.  An ink film composed of tin(II) carboxylate compound is applied to the surface and heated to partially decompose the compound.  A positive photoresist layer is preferably applied to the partially decomposed layer and selectively irradiated to define a mask overlying the selected region.  Unwanted photoresist material is dissolved from the adjacent region using an aqueous alkaline solution.  It is found that the solution concurrently dissolves the underlying partially decomposed tin compound, without dissolving the compound protected by the mask.  Thereafter, the mask is stripped, and the underlying tin compound is heated and further decomposed to produce the desired tin oxide thin film.

Granted: 1992-12-01
Abstract: TITLE            An Improved Method for the Production of Seamless Titanium Alloy Tubing and the Like ABSTRACT OF THE DISCLOSURE         A process for the production of seamless titanium alloy tubing is disclosed in which solution annealing for all intermediate operations are performed in an air atmosphere furnace, followed either by water or room temperature air quench in order to achieve cooling within the requisite five (5) minutes.  Preferably final aging is performed in a vacuum furnace to avoid surface contamination which would ordinarily require subsequent removal by pickling.  This produced a finer grained product, which was more susceptible to defect detection by ultrasonic testing, which produced an optimum combination of strength and ductility, and which showed more uniform response to aging between different lots and tube sizes.

Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE      An  interface  between  a  product  planning conceptual design tool and a CAD/CAM environment allows an indented bill of materials to be imported to  the  CAD/CAM  environment  while  retaining  the characteristics  as  a primitive  text  file.  The conceptual design tool uses a sketch sheet approach on  a  computer  display  to  enter  the  functional design  of  a  new  or  modified product,  thereby encouraging the designer to use a top down approach to  the design process.   The user  keys  in item information, and the system automatically draws a hierarchical  tree  structure  on  the  computer display.   The system then automatically generates an indented bill of materials which is stored in a graphics standard file that retains the character of text primitives.  From this file an image of the bill of materials can be displayed in the CAD/CAM environment.  The designer can use this image as an aid in the design process.  Item names and numbers can be copied from the displayed bill of materials to the CAD/CAM image.   The bill of materials can also be edited in the CAD/CAM environment and the edited bill of materials can then be reconstructed in  the  conceptual  design  tool  for  use  in  the continuing design and planning process.

Abstract: ABSTRACT OF THE DISCLOSURE The disclosure concerns  a  regulator  for moving a window  in  a  vehicle  door  successively  substantially vertically and horizontally to close the window, and in reverse to open the window.   Once the window is closed vertically the lower edge is moved outwardly horizontally to become substantially flush with the outside surface of the door of the vehicle.  The regulator comprises a closed loop of cable wrapped about a reversible driving drum and having a vertical reach which is attached to a pulley connected to the window carrier.  This pulley is provided with a pair of diametrically opposite cam follower pins or rollers that are guided in a vertical slot parallel to the vertical reach of cable.   The slot is bifurcated into diverging cam slots at its upper end for rotating the pulley as the cable means continues to pull.  The pulley has a projection with a helical groove that receives a pin carried by a window-mounting carrier so that rotation of the pulley moves the carrier and lower edge of the window horizontally.  When the cable pulls in the other direction the window and carrier are cammed inwardly horizontally before lowering the window carrier to open the window.
