Abstract: The implementation of BRI/ISDN services is changing the way services can be maintained with existing operations support systems. For example, with ISDN a subscriber to the service can initiate and effect a move of his directory or telephone number from one location to another without directly involving the operating company. The subscriber, by moving his directory number to a new location, now receives his service over a new transport facility. As a result, the records of the operating company which identify a specific transport facility to a specific telephone number cannot be readily updated to reflect subscriber moves. Thus, if the records of the operating company do not identify the transport facility which is associated with the directory number at the new location the operating company cannot readily process trouble reports against the service. The new operations system and electronic processing switch methodology disclosed solves the major operational problems associated with processing a trouble report on BRI/ISDN service in an environment where the subscribers can move their own services. In operation, this invention initiates a trouble report on an ISDN service line record and then links the report to the appropriate facility line record information for repair processing based on an identifier obtained from the electronic processing switch.

Abstract: An image detector (e.g. for X-ray images) includes an array of photodetectors (40,42,44) arranged in n rows and m columns with at least a portion of the photodetectors in each column being selectively connected to a common column output signal line (48⁻¹ - 48-m by a selector means. the image information is read out of the photodetectors by sequentially selecting groups of rows starting with a row near the middle of the array and then sequentially selecting other groups of rows on alternate sides of the array middle. As image data is read out of the photodetectors (40) in the selected row group, groups of column output lines (48) are coupled together to provide a combined output signal. This readout technique provides a reduction in the image data and reduces the likelihood of signal degradation for the central portion of the image.

Filed: 1992-05-11
Abstract: An image is tested to determine whether it is substantially like a plurality of sample images by computing statistical information about the sample images and using that statistical information to analyze the image being tested. The analysis is such that the statistical parameters are standardized so that available tables of the central chi-square distribution function can be used, thereby simplifying the necessary calculations. If desired, images which have been determined by the method of this invention to be good can be used to refine the statistical information used in analyzing subsequent images. When an image is identified as unacceptable by the method of the invention, the data for that image can be decomposed in order to identify the parts of the image which are causing the image to be unacceptable.

Abstract: A pulsed imaging, facet tracked, Raster Output Scanner utilizes pulse width modulation in conjunction with spatial filtering to form three exposure levels at the surface of a charged photoreceptor medium (10), one of the levels associated with a specific color. This type of scanner with a nominal video rendering experiences a color line growth in the process direction. The line growth problem is caused by a coherent optical effect. The resultant output print has bolded color lines in the process direction. Several techniques are set forth to compensate for this line growth. In a preferred technique (Figures 12a and 12b), the video data stream is modified by locating or positioning video pulses representing white information at the start of an associated pixel time period. When the color pixel is imaged, it will therefore, always abut an adjoining white pulse and will be inhibited from spreading into the adjacent pixel period. Other techniques rely upon inversion of white pulses, or separation of white pulses into two signals, each segment moved to the beginning and the end of the associated pixel period (Figures 14a and 14b). According to another technique, the input data stream is buffered and pixel groups examined to identify neighboring white and color signals. These signals are then either narrowed or in the case of a sequence of color signals, the lead and trail edge of the color signals are trimmed (Figures 15 to 19).
