Patent EP-0459522-A2 (EP)
Inventor: MURATA KENJI
IPC: H02H7/26
Filed: 1991-05-31
Abstract: A method of locating a fault point in a parallel two-circuit transmission line in an n-terminal system. When a single fault occurs at one place in one circuit of the transmission line and when a multiple fault occurs at the same place in the two circuits, a distance to the fault may be calculated by the method of this invention. The method comprises the steps of transforming the transmission line into a T three-terminal parallel two-circuit transmission line circuit having three branches, calculating a value representing a length of one of the three branches on the basis of differential currents flowing into the branch points of the transmission line, determining if that value represents the distance from a terminal connected to the branch point to the fault point, employing the value as the distance to the fault point if the value represents such a distance, repeating the value calculation and determination for the other two branches if the value does not represent the distance to the fault, determining a next branch point for which to perform equivalent transformation with respect to, and repeating the previous steps until the fault is found.

Abstract: Apparatus and method for insuring data cache content integrity among parallel processors. Each processor has a data cache to store intermediate calculations. The data cache of each processor is synchronized with each other through the use of synchronization intervals. During entry of a synchronization interval, modified data variables contained in an individual cache are written back to a shared memory. The unmodified data contained in a data cache is flushed from memory. During exiting of a sychronization interval, data variables which were not modified since entry into the synchronization interval are also flushed. By retaining modified data cache values in the individual processors which computed the modified values, unnecessary access to shared memory is avoided.

Abstract: The period of an initial apply motor current in each apply phase of an antilock brake control cycle in an antilock braking system having a motor (30) driven pressure modulator (18) is adaptively controlled following a sensed recovery from an incipient wheel lockup condition to establish substantially a steady state condition relationship between current and pressure before motor current is ramped to ramp brake pressure. The period of the initial apply motor current is made a function of the amount of pressure decrease during a prior release phase portion of the antilock brake control cycle to account for the greater increase in brake pressure to the initial reapply value.

Abstract: The present invention relates to a method and apparatus for merging command/data packets from a plurality of parallel processing units into a concentrated data stream, while also providing for pipeline attribute data storage, direct user access to the pipeline, redirection of the pipeline, data insertion into the pipeline and pipeline diagnostics. The data from a plurality of parallel processing units is recombined in the same order as originally transmitted and then inputted into a buffer for entry into the pipeline. Attribute switching commands are deciphered by the concentrator of the invention and selectively stored and retrieved from the pipeline. New attribute values are passed downstream on command when they are different from existing attributes, or conversely, the concentrator may be overridden by the user so that attribute values supplied by the user may be stored and passed downstream. This technique thus minimizes repetitiveness in attribute switching. Further diagnostics capabilities are provided whereby a user of the graphics processing system is given the ability to plug the pipeline and independently check different data sources and destinations to see if they are functioning properly. This process is further enhanced by the capability of the invention to check the status of each of the concentrator elements in parallel to determine if they are ready before performing any data transfer.

Abstract: The hierarchy of the hyphenation points in a word is considered and the amount of space remaining in the line where the hyphenated word is to fit is determined, thus selecting the best hyphenation point for the word. Instead of selecting the last possible hyphen within the hot zone (HZ), the hot zone (HZ) is scanned to find hyphenation points that may be better than the last hyphen within the hot zone (HZ). The higher a hyphenation point is in the hierarchy, the more preferred is the hyphen.

Abstract: Characteristics of images, such as skew of lines of text or dominant typeface of characters, are detected by producing distance data for each of a number of starting pixels within an image. Each starting pixel meets a criterion, such as an edge pixel or a pixel inside a connected component. Each starting pixel's distance data indicates the distance in each of a number of directions from the starting pixel to another pixel at which the image meets another criterion. For example, to detect skew of lines of text, the distance data can indicate distance from a starting pixel at an edge across white pixels to another edge. To detect dominant typeface, the distance data can indicate distance from a starting pixel at an edge or inside a connected component across black pixels to another edge. The separating angle between adjacent directions can be small enough to detect features of an appropriate size at an appropriate distance, such as features of character size at the average intercharacter spacing. The distances at each direction from all the starting pixels can be averaged to obtain a combined distance at each direction. A sufficient number of starting pixels can be used so that the combined distance is approximately the same as if every pixel in the image were a starting pixel. The combined distances at all the directions form a profile. Skew can be determined from peaks in a profile. A profile can be compared with each of a set of model profiles to detect typeface.
