Title: Protective shield for a turbo-engine
Inventor: GLOWACKI PIERRE ANTOINE
IPC: F02K1/82
Filed: 1995-12-18
Abstract: Protective shield (9) for a turbo-engine external fairing (3). It comprises a ring made of a ductile material retained by several fastening means relatively easy to break. When a rotor portion (17) accidentally detached strikes it, it dents it breaking some or all of its fasteners. By means of this possibility allowing for wide deformations of the shield (9), the capacity for absorbing energy is significant.
Patent CA-2165624-A1 (CA)
Inventor: GILLILAND MALCOLM T
IPC: B25J9/18
Filed: 1995-12-19
Abstract: A method for preventing collisions between robots by causing a first robot to stop or pause so that a second robot may safely pass by or perform a specified operation. Once the second robot has completed its operation then the first robot is allowed to resume operation. Each robot automatically stops when it reaches a certain point in its job. The robots communicate with a central controller which allows the robots to resume operation when the central controller has determined that all of the robots have reached their respective correct positions. This prevents collisions between robots which are operating in the same area, especially those robots operating on the same workpiece. This method works with existing robot welders, does not require modifications to the robots, and does not require expensive spatial analysis computer programs, which may not even be available for the type of processor used in a particular robot. The present invention also provides a method for specifying a compartment entry point for a welding operation based upon data provided from a CAD program. The present invention also provides a method for automatically determining the starting and ending coordinates of a weld using a touch-sensing capability of the robot. The present invention also provides a method for automatically tracking the joint for a welding seam by periodically measuring the coordinates of the components by using the touchsensing feature of the robot. The present invention also provides a method for automatically determining the position of a torch to provide for an optimum angle of attack for a welding operation based upon data, such as beam height and flange overhang, provided from a CAD program. The present invention also provides a method for automatically tracking the joint for a welding seam by weaving (dithering) the torch along the desired path, measuring the arc welding current at peak deviations from the travel path, and comparing the measured current on the two different sides of the weld to determine whether the torch is on the seam. The present invention also uses this method to automatically track the edge of a component for applying a welding bead to the edge of the component. The present invention also provides for automatically selecting a welding program from a standard set of welding programs based upon data from a CAD program.

Title: Compact device for monitoring asynchronous transfer mode cells
Inventor: YAMASHITA HIROSHI
IPC: H04L12/26
Filed: 1992-01-15
Abstract: In a device for checking a header error in a header part of an STM (synchronous transfer mode) signal (S) which part comprises first through P-th header blocks and an HEC          (header error check) block, each header block comprising first through N-th ATM (asynchronous transfer mode) cell header units, the HEC block comprising first through N-th ATM cell HEC units, a sole error checking section (33, 35, 37) checks the header error in connection with an n-th ATM cell header unit of a p-th header block and an n-th ATM cell HEC unit when a collective control signal indicates the n-th ATM cell header unit of the p-th header block and the n-th ATM cell HEC unit, where n 18 variable between 1 and N, both inclusive, p being variable between 1 and P, both inclusive. A signal producing section (15) produces the collective control signal for indicating successively the first through the N-th ATM cell header units of the first through the P-th header blocks and subsequently successively the first through the N-th ATM cell HEC units.  On monitoring an ATM cell of a preselected  number of bytes, the ATM cell may be converted into a converted cell of the preselected number of bytes plus an empty byte at first.  Subsequently, an error correcting code is calculated from the preselected number of bytes of the converted cell and is placed in the empty byte to form a full cell.

Patent CA-2173177-A1 (CA)
Inventor: TSUKAGOSHI IKUO
IPC: H04N19/70
Filed: 1996-04-01
Abstract: Colorwiping and dynamic positioning of subtitles is achieved by encoding and decoding the subtitles separately from the video image. At the encoder, subtitles are generated for each respective video image. Colorwiping is performed by changing the color of the subtitles at a certain location in the video image. At the decoder, a buffer stores the subtitles along with subtitle decoding information. A controller precisely times a reading operation of the buffer to read out the subtitles during a real time display of the respective video image; and colorwiping is performed by changing the color of a portion of the subtitles at a location indicated by the subtitle decoding information. Dynamic positioning of the subtitles is achieved by delaying the time the controller executes the read operation. When the decoding technique is repeated for a number of frames, the viewer senses motion as the colorwiping and positioning gradually changes.

Title: Lifting folding door
Inventor: MEGENS JOHANNES HENDRICKUS
IPC: E05D15/26
Filed: 1995-09-22
Abstract: The invention concerns a lifting folding door (3), containing: two primarily vertically extending rails (4), arranged each on one side of the opening (2) to be closed by the door (3); a number of panels (8) hinged together, each of them guided by both rails; guiding means (6) connected at the top of each of the rails for guiding the panels such that, when moving upward, they are folded together in zigzag fashion by means of their hinge connections (12, 13) in primarily horizontal direction above the rails; operating means for driving at least one of the panels in vertical direction, in which the guiding means are designed for gradually deflecting the panels in horizontal direction, starting from the vertical movement. As a result of these steps, a purely vertical movement is gradually converted into a movement of a horizontal component, so that the dynamic forces acting on the respective elements are less, and therefore the speed can be significantly increased.
