Title: Single pass marker enclosed area detection system and method for a photocopier
Inventor: SHIAU JENG-NAN
IPC: G06V30/10
Filed: 1994-07-22
Granted: 1997-07-15
Abstract: The present invention provides a marker detection and thinning process for a photocopier which is executed during a single scan of a document and does not require a prescan of the document. The system realtime analyzes pixel image data, which is stored in a memory during the scanning process, to detect a marker line of a predetermined color and to thin the marker line. This analysis begins with image data stored in the memory that corresponds to a first pixel. The first pixel is associated with the scanline being presently scanned. It is determined if the image data of the first pixel represents a color that is equivalent to the predetermined color. Marker data is then stored in a buffer at a location corresponding to the first pixel if it is determined that the image data of the first pixel represents a color that is equivalent to a predetermined marker color. The data, stored in the buffer at a second pixel location, is analyzed. The second pixel is associated with a scanline that is prior in time to the scanlineof the first pixel. It is determined if the data at the second pixel location ismarker data. Also, the data stored in pixel locations adjacent to the second pixel location is analyzed to determine if this data is marker data. The marker data at the second pixel location is eliminated if it is determined, upon examining data of pixel locations adjacent to the second pixel location, that the elimination of this marker data would maintain the connectivity of the marker line. However, the data at the second pixel location is maintained if it is determined that, upon examining the data of pixel locations adjacent to the second pixel location, the elimination of this marker data would cause disconnectivity of the marker line.

Abstract: A conference bridge that receives speech data in the form of data packets, and transmits data in the same form, without transforming the data in the conference bridge. The conference bridge according to this invention includes a plurality of inputs that have speech detectors that detect the presence of speech data. The speech detectors report the presence of speech to a controller. The controller causes data packets from one of the inputs detecting speech to be replicated for all outputs. If there is speech at more than one input at a time, then a decision is made as to which input to replicate. Advantageously, the decision is based on who is the loudest speaker. Further, the data that is replicated is not sent to the output for the originator in order to prevent echo.

Abstract: A field-installable rod guide firmly grasps the sucker rod to which it is attached and reduces fluid friction to axial movement of the rod guide. The rod guide includes one or more channels for fluid to flow by the guide through straight or helical vanes. An axial access channel which permits application of the rod guide onto a sucker rod has a wide, tapered mouth to minimize the length of time during which the guide is stretched during installation. Recognizing that some stretch is inevitable in the guide at the point opposite the axial access channel, more rod guide material is placed at this point of greater stretch. In a preferred embodiment of the present invention, the rod guide stock from which the rod guide is machined is extruded to form the desired vanes as well as a non-circular "rod hole." This way, a "dual-radius" hole is enabled. The dual-radius hole narrows the gripping radius of the guide to solidly grasp the rod and eliminate slipping of the guide on the rod.

Title: Method and apparatus of establishing a vehicle azimuth
Inventor: BENNETT SIDNEY M
IPC: G01C21/28
Filed: 1995-06-07
Granted: 1999-02-16
Abstract: The method and apparatus of establishing a vehicle azimuth provides for the automatic establishment of the vehicle azimuth for a vehicle positioning mechanism, and the continued improvement of accuracy, if desired. The method and apparatus accomplishes this by obtaining an assumed initial azimuth and an actual path azimuth as the vehicle passes in the vicinity of a first beacon. The actual path azimuth can be determined as between the first beacon and a subsequent beacon further along theroute, or alternatively, the first beacon can be associated with a restricted, travel path or path segment having the actual path azimuth at the exit of the maintenance garage or ferry dock. The vehicle positioning system dead reckons its position from thevicinity of the first beacon and establishes an apparent path azimuth for the vehicle over the same path having the actual path azimuth.  The difference between the actual path azimuth and the apparent path azimuth is the initial offset angle. The initial offset angle corrects the assumed initial vehicle azimuth to obtain the vehicle azimuth. As the vehicle traverses more distance between the adjacent beacons or alternatively along the restricted travel path or path segment, the accuracy of the initial offset angle improves because the dead reckoning calculation becomes more accurate.  Furthermore, when the vehicle passes a subsequent beacon, any ambiguity with respect to the vehicle azimuth is corrected because the coordinates of the first and second beacons or, alternatively, of two GPS positions are known, and the actual path azimuth between the two beacons or positions can be used to offset the apparent path azimuth calculated solely by dead reckoning with the assumed initial vehicle azimuth.
