Abstract: A technique for processing natural language text uses a data structure that includes structure data in the text data. The structure data indicates an autonomous punctuational structure of the text, a punctuational structure that is independent of the lexical content of the text and therefore can be manipulated without considering the meaning of the words in the text. The data structure can be a tree in which each node has a textual type such as a paragraph, sentence, clause, phrase, or word. The data structure could alternatively be parallel data sequences, one with codes indicating the text's characters and the other with codes indicating textual types. The data structure is produced and maintained using a grammar of textual types, indicating for each textual type the textual types of units into which it can properly be divided. During editing, a text sequence is generated by applying rendering rules to the data structure, and the text is presented to the user based on the text sequence.

Abstract: An object is exposed to penetrating radiation at each of a plurality of partial rotations of the object. Radiation transmitted through the object strikes a separate sheet of radiographic film for each exposure to record an entire radiographic image of the object for each angular orientation. The radiographic images are digitized and stored in the memory of a computer. Each digitized image is registered by determining the error of rotation and center of rotation for each digitized image and correcting for the error of rotation by rotation and translation of pixel values. One or more displacement values are selected in correspondence with one or more desired levels of view and the digitized images are displaced according to the selected displacement values. The displaced images are then combined to produce images representative of the selected levels of view. Image planes non-parallel to the film image plane may be selected and interactive image enhancement and manipulation are provided.
Abstract: Data for reproducing music and displaying words are composed of binary-coded digital signals. Such signals are down-loaded via a public communication line, or data corresponding to a plurality of musical pieces or songs are previously stored in an apparatus, and the stored data are selectively processed by a CPU. In the instrumental music data, trigger signals are existent for progression of processing the words data, whereby the reproduction of music and the display of words are linked to each other. The music thus reproduced is utilized as background music or for enabling the user to sing to the accompaniment thereof while watching the words displayed synchronously with such music reproduction.

Abstract: A method of reducing image artifacts in tomographic, projection imaging systems due to periodic motion of the object being imaged includes the acquisition of a signal indicative of the periodic motion. This signal is used to identify a quiescent period in the periodic motion so that the acquisition of projection data may be coordinated to be centered within the quiescent period. The sequence of the angles at which projection data is acquired is controlled so that the primary axis of periodic motion is perpendicular to the axis of projection at the center of the quiescent period. Multiple periodic signals may be coordinated by awaiting their best alignment over a fixed number of cycles of one of the periodic motions.
Abstract: A computer tomography apparatus has an x-ray source with a focus, with the focus being periodically deflected during data acquisition, specifically during mean value formation of the signals obtained by the radiation detector. The mean value formation is not undertaken simultaneously for all detector elements, but instead is undertaken chronologically offset from detector element to detector element. A memory in which the analog measured values available at the end of an interval would be stored is thus not needed.
