    摘要： 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.

    摘要： 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. The second pulse has a pulse height magnitude greater than the sufficient pulse height magnitude of the first pulse and a pulse width which is insufficient to switch the selected pixel.

    摘要： 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.

    摘要： 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. The addressing step includes setting a group of blocks, the group consisting of a plurality of blocks spaced apart in the addressing sequence such that the blocks in the group form a series with adjacent blocks having a temporal separation in the addressing sequence exhibiting a geometric progression with a common ratio N being an integer equal to 2 or more. In this way, addressing of the lattice occurs simultaneously with its illumination by the appropriate color, allowing a greater proportion of the frame time for the addressing operation so that additional addressing information can be utilized.

    摘要： 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. The first split roller section is substantially conical in shape and has a large diameter side located proximate to one of the bearing surfaces. The first split roller section is rotatably disposed on and axially slidable toward the one of the bearing surfaces and tangentially engages the rack bar. The second split roller section is also substantially conical in shape with a large diameter side located proximate to an other of the bearing surfaces. The second split roller section is rotatably disposed on and axially slidable toward the other of the bearing surfaces and tangentially engages the rack bar. Low friction radial bearings are disposed between the dowel pins and the roller sections. Low friction thrust bearings are axially disposed between the roller sections and the bearing surfaces of the support yoke. The spring acts against the support yoke to press the roller sections against the rack bar, causing the rollers to separate from each other and thereby defining a gap therebetween and pressing the washers against the bearing surfaces of the support yoke.
