  • Publication number: 20040193391
    Abstract: Methods and apparatus solving problems of polygonal approximations of isosurfaces extracted from uniformly sampled volumes increasing in size due to the availability of higher resolution imaging techniques. The large number of primitives represented hinders the interactive exploration of the dataset. Examples of methods are provided for adaptive isosurface extraction that are generally easy to implement and allows the user to decide the degree of adaptivity as well as the choice of isosurface extraction algorithm. The extraction of the isosurface is optimized by warping the volume. In a warped volume, areas of importance (e.g. containing significant details) are inflated while unimportant ones are contracted. Once the volume is warped, any extraction algorithm can be applied. The extracted mesh is subsequently unwarped such that the warped areas are rescaled to their initial proportions. The resulting isosurface is represented by a mesh that is more densely sampled in regions decided as important.

  • Patent number: 5983742
    Abstract: A steering gear for a motor vehicle includes a housing, a rack bar, a pinion, a support yoke, a spring, a split roller, and a plurality of bearings. The rack bar is slidably supported within the housing for transverse displacement therein along an axis. The rack bar has teeth on a first side. The pinion has teeth drivingly engaging the teeth of the rack bar. The pinion is rotatably supported within the housing. Rotation of the pinion transversely displaces the rack bar along the axis. The support yoke is slidably disposed in the housing for movement toward a side of the rack bar substantially opposite the teeth of the rack bar. The support yoke has an opening which is open toward the rack bar, with the opening defining two opposed bearing surfaces. The spring is disposed between the housing and the support yoke, and biases the support yoke toward the rack bar. The split roller includes a first split roller section and a second split roller section.

  • Patent number: 5388407
    Abstract: An exhaust manifold catalytic reactor and muffler for an automotive internal combustion engine includes at least one exhaust branch for conducting exhaust gases from the cylinder head exhaust ports of an engine to a hollow, generally cylindrical primary catalyst substrate for treating the exhaust gases flowing from the engine. The substrate has inner and outer surfaces which are generally cylindrical and which define an inner cavity. A housing connected to the exhaust branch places the exhaust gases in contact with the substrate and includes a generally cylindrical container having an outer wall and a transition section conducting the exhaust gases from the branch to the outer surface of the substrate such that the initial flow of the gases from the branch to the outer surface of the substrate such that the initial flow of the gases from the substrate is generally tangential.

  • Patent number: 5336248
    Abstract: The present invention relates to an apparatus for the treatment of or the inhibition of retinopathy of prematurity and to a method for treating or for inhibiting retinopathy of prematurity. The apparatus provided in accordance with the present invention includes a component or system for providing substantially only red light. Thus, light is provided having a wave band of approximately 612 nm or more. Furthermore, at least the patient's head is received in a device that limits the light which reaches the patient's eyes to the aforementioned red light. Thus, the patient is allowed to see substantially only red light.

  • Patent number: 5189406
    Abstract: The display has a video signal receiver and a store with a capacity to hold one picture of the video signal. Row-output devices enable the video information for respective rows of pixels to be taken out from picture store, and each has a bit extractor to separate out one bit of the information for each pixel of the respective row. The resultant signal is passed to pixel drivers which operates on a lattice formed of ferroelectric liquid crystal pixel-elements, which are time-multiplex addressed according to a predetermined sequence, each row being addressed a plurality of times for each picture. In the addressing groups of the rows are set simultaneously, each group consisting of a plurality of rows spaced apart in the addressing sequence such that the rows in a group form a series with adjacent rows having a temporal separation in the addressing sequence exhibiting a geometric progression with the common ratio N being an integer corresponding to 2 or more.

  • Patent number: 5132678
    Abstract: A method of operating a display comprising a lattice of pixel elements, includes the step of time-multiplex addressing collections of pixel elements. This addressing step includes using a first shift register means to designate operation of a second shift register means to select a function to be performed. If the second shift register means is in bypass mode, then the first shift register means is effective as a mask to specify which of the stages in the second register means should be bypassed, and allows non-sequential group addressing of the pixel elements. Such an arrangement of first and second shift register means is suitable for use in controlling the addressing of collections or rows of pixel elements; the function to be selected by the second shift register means is the strobing of the collections or rows.

The arrangement is such that each of the plurality of means to produce respectively a plurality of output waveforms is capable of producing an output waveform having at least four voltage states. The drive circuit produces a plurality of outputs suitable for driving a matrix-addressed display.

  • Patent number: 5093652
    Abstract: A display device has a lattice of pixel elements each selectably settable. A method of operating the display device comprises the steps of receiving a signal representing a picture for display during a display period and illuminating the lattice to produce, during a first interval within the display period, a first light output from the lattice having a first predetermined color characteristic and to produce at least one additional light output from the lattice. Each said additional light output has a different predetermined color characteristic and a respective interval within the display period separate from the first interval. The method further comprises the step of time-multiplex addressing blocks of pixel elements a plurality of address times during each interval.

  • Patent number: 5010328
    Abstract: A method is provided for addressing a matrix-array type liquid crystal cell with a ferroelectric liquid crystal layer having a plurality of pixels defined by areas of overlap between members of a first set of electrodes on one side of the liquid crystal layer and members of a second set of electrodes on the other side of the liquid crystal layer, each of the pixels having a first and a second optically distinguishable state and a response time for switching between the two states which depends on the potential difference across the liquid crystal layer. The method includes the step of applying a switching pixel waveform to a selected pixel to switch it between the two states. The switching pixel waveform is charge-balanced and comprises a first pulse having a sufficient pulse width and pulse height magnitude to switch the selected pixel and a second pulse contributing to charge-balancing.
