Patent CA-2227087-A1 (CA)
Title: Laser aligned robotic positioning system
Inventor: CHURCHILL RUSSELL J
IPC: G05B19/18
Filed: 1998-01-15
Abstract: A precision positioning system is used for resurfacing and repairing rails and guideways of large, heavy machinery at users facilities. The system has new components, an entire machining system, a new alignment system, parallel platforms for tool support and surface scanning. A sectioned, portable monorail frame is held by fixed supports at the locus of a heavy machine requiring guideway straightening. Fixed guides extend along the outer surface of the monorail. Guide wheels and drive wheels contact the guides and support and move an outer tubular beam carriage. An assembly of machining tools is adjustably positioned on the carriage. Laser alignment sources and sensors are connected to the carriage and to heavy machines off-axis and parallel to the monorail. Intelligent controls precisely position the tools for resurfacing the rails and guideways. Scanning and a printout of machine guideway accuracy, before and after the operation, provide written verification of quality improvement. The system increases accuracy and speed of machining, reduces chatter and vibration, eliminates imprecise manual determinations, and returns the equipment to acceptable improved tolerances. The system has applications in any machine tool rebuilder or company with a machine tool in need of requalification. Applications also include rail transport, autonomous vehicles, micro-machining, inspection camera positioning, laser machining, material deposition and other operations such as drilling, heat treating, brazing and welding.

Title: Method of stabilizing the horizon of magnetic compasses
Inventor: DITTRICH FRANK
IPC: G01C17/38
Filed: 1996-08-21
Abstract: Disclosed is a method of stabilizing the horizon of magnetic compasses. At measuring points measurements are taken of spatial components of the geomagnetic field vector and of an overall acceleration vector that is equal to the difference of the acceleration vector due to gravity and the acceleration vector of the magnetic compass. Taking into account the time rates of change of the measured components, the positional relation of the current horizon of the magnetic compass is determined relative to the stable horizon. Using quality functions that signal the deviation of the new spatial position relative to the one previously defined, an estimation method is used to evaluate the accuracy of the stabilized horizon of the system. A horizon can be produced that is largely unsusceptible to movement-induced accelerations of the device equipped with a magnetic compass.

Title: Furnace with dual use inducer motor
Inventor: ROETKEN RICHARD L
IPC: F23N3/08
Filed: 1998-02-09
Abstract: An improved furnace including a two-speed inducer motor which can be used as a single speed motor for either a vertically or horizontally vented furnaces. The inducer has a common terminal, a low speed terminal and a high speed terminal. One lead is attached to the common terminal and, depending on whether the furnace is vented horizontally or vertically, either the high speed or low speed terminal is used. If the furnace is vented vertically, one lead is connected to the common terminal and the other lead is connected to the low speed terminal. Thus the furnace operates at a low speed when the furnace is vented vertically. If the furnace isvented horizontally, one lead is connected to the common terminal and the other lead is connected to the high speed terminal. Thus, the inducer motor operates at thehigher speed when the furnace is vented horizontally.

Inventor: COHEN MICHAEL F
IPC: G06T15/20
Filed: 1998-03-19
Abstract: A method and computer product for rendering real-time three-dimensional images on a display based on view manipulation of prestored depth images in a global coordinate space. First, a layered depth image is generated from multiple depth images based on a predetermined display viewpoint. If the determined viewpoint is within a predetermined threshold of the layered depth image, the generated layered depth image is warped based on the determined display viewpoint, pixels from the layered depth image are splatted onto the warped image, and an output image is generated and displayed based on the split pixels. If the determined viewpoint is outside the predetermined threshold of the previously generated layered depth image, a next closest layered depth image is generated. If the next closest layered depth image is not fully generated, the preciously generated layered depth image is used to generate an output image. If the next closest layered depth image is fully generated, the process is repeated for the generated next closest layered depth image.

Title: Tilting-bowl toilet
Inventor: YEUNG SHU-KI
IPC: E03D11/02
Filed: 1998-07-17
Abstract: To eliminate the necessity of a water tank, this invention converts the traditional toilet bowl with siphonic water trap  into  a  toilet  basin  with  a  tilting-bowl.    This invention comprises a frame, a toilet basin, a tilting bowl and a trigger means.  The tilting bowl is mounted to pivot as a movable water/waste container.   In its not tilted horizontal position,  the tilting bowl receives and holds water/waste delivered to it through the toilet basin.  When the  tilting  bowl  tilts,  it  discharges  its  content  to drainage pipe   through   a   bottom   discharge   hole; simultaneously allowing water/waste to discharge from basin to drainage.  The tilting bowl is normally retarded to stay in its horizontal position by forces applied to the tilting bowl creating a resultant retarding turning moment about its pivot point larger than the turning moment produced by the tilting bowl  with its  content.   The  trigger means serves to remove or reduce the retarding turning moment, allowing the tilting bowl to tilt to discharge water/waste to outside the toilet.

Title: Data processing method and apparatus for handling exception events in application programs
Inventor: GAMO TSUTOMU
IPC: G06F11/30
Filed: 1998-07-30
Abstract: A data processing method capable of easily assembling plural exception processing environments. In executing an application program, an object to be fed with an error message on occurrence of an exception event which is likely to cause interruption of the normal execution of the application program is previously registered. If an exception event has occurred, an exception occurrence message indicating occurrence of the exception event is sent to a pre-set object. The object, thus fed with the exception occurrence message, generates an error message corresponding to the exception event indicated by the exception occurrence message and sends the generated error message to the registered object. This object sends a message commanding execution of a pre-set processing corresponding to the error message to the application program responsible for the exception event.
