Abstract: A method and apparatus for addressing faster responding liquid crystal panels (LCDs) so that video rate, high information content LCDs having time constants on the order of 50ms or less, are perceived as having brighter bright states and darker dark states by limiting peak voltage levels across the pixels. A first set of LCD electrodes are continuously driven with signals each comprising a train of pulses that: are periodic in time; have a common period T; are independent of the information to be displayed; and are preferably orthonormal. A plurality of column signals are generated from the collective information state of the pixels defined by the overlap with a second electrode pattern. Each column signal is proportional to the sum obtained by considering each pixel in the column and adding the voltage of that pixel's row at time t to the sum if the pixel is to be "off" and subtracting the voltage of that pixel's row at time t from the sum if the pixel is to be "on". If the row signals only switch between two voltage levels, the sum may be represented as the sum of the exclusive-or (XOR) products of the logic level of the amplitude of each row signal times the logic level of the information state of the pixel corresponding to that row. 
     Hardware implementation comprises an external video source, a controller that receives and formats video data and timing information, a storage means for storing display data, a row signal generator, a column signal generator, and at least one LCD panel. Alternative embodiments provide gray scale shading and circuits to reduce the magnitude of the column signals, as well as the number of column voltage levels required to generate a displayed image.

Abstract: A thermal printer is capable of printing proofs of images on a receiver with any of a plurality of selected half-tone dot patterns. The proof image is generated with a series of incremental dots. A plurality of the incremental dots are generated substantially simultaneously as a swath. The image is formed as a composite of a plurality of the swaths. The printer has the capability of printing with various swath widths. The swath width for a particular image is selected to preclude visible beating of the incremental dots against the selected half-tone dot pattern. Any image artifacts which are a product of interaction of the selected half-tone dot pattern and image elements (such as picket fences) are properly illustrated on the proof image. Image artifacts that are the product of interactions of the incremental dots and the half-tone dots are made invisible to the human eye.

Abstract: A digital data processing apparatus includes a processing element that executes a process for generating request for access to mapped data in a memory element. The apparatus also includes a fork/checkpoint-signalling element that generates "new-process signals" which delineate new time intervals. The apparatus responds to data requests generated by the process before the first new-process signal by accessing a requested datum as stored in a first set in memory. An address space manager responds to certain requests, e.g., for write access, in subsequent intervals for copying the requested datum from the most recent set in which it is stored to the current interval and, thereafter, accessing that copy. The manager responds to other requests, e.g., those fore read-type access, by accessing the requested datum in the most recent set in which it is stored. A fork element can create a second process that initially duplicates a first one and can initiate generation of a new-process signal in connection with creation of the second process.

Abstract: 5 n7 The present invention is for a deflective or flexible tube having an essentially smooth inner surface. The tube comprises in its longitudinal direction several with each other identical sections. These are characterized by that each section can be said to be divided in to parts in its longitudinal direction whereby the first part has an smooth inner surface. The first part further has an outer dimension which is close to the inner dimension of the second part whereby the first part of one section can be inserted into the second part of an adjacent section. The parts are of about the same length and the smooth inside of the first parts will therefore form the inside of the tube. 
     For the assembly of the sections to a tube the tube walls are bent so that between the first and the second part of each section there is an L-shaped projection. In the outer end of the second part there is as an end of the tube section a second L-shaped projection which is similiar to the first projection but has somewhat greater dimensions so that the second projection grips around the first one in such a way that some movement is possible.
