Abstract: A neuromodulation therapy system includes a programmer and a stimulation system. The stimulation system is capable of storing multiple data sets, each data set effecting an independent therapy. The stimulation system includes a display mechanism that can display certain imagery to distinguish visually one therapy from another therapy.

Abstract: Methods of reducing artifacts in SLM-based display systems (10, 20), whose images are based on data displayed by bit-weight for pulse-width modulated intensity levels. A first method is suitable for systems (20) that use multiple SLMs (14) to concurrently display images of different colors, which are combined at the image plane. The data for each color are staggered in time (FIG. 4). A second method is suitable for either multiple SLM systems (20) or for systems (10) that use a single SLM (14) and a color wheel (17) to display differently colored images sequentially. The data for each color is arranged in a different data sequence (FIG. 5). In either method, the intensity transitions do not occur at the same time.

Abstract: A method of reducing the effects of aliasing. Pixels are divided into phases, such that a phase or combination of phases may be printed to provide one of a number of dot shapes for each pixel. When a pixel is partly overlapped by an object to be printed, that pixel's dot shape is determined by determining which dot shape is the best geometrical match with the overlap. (FIGS. 3 and 7). Then, a greyscale value is determined for the selected dot shape by determining what greyscale will provide an effective greyscale that substantially corresponds to the percent of overlap by the object with the pixel. An alternative method selects a greyscale value for each phase rather than for the entire dot shape.

Abstract: A method of eliminating the effects of aliasing when printing objects having opposing edges. A center line between the opposing edges is identified. (FIG. 3). "Opposing pixels" on the edges are also identified and assigned offsetting grayscale values. (FIG. 4). This prevents the distances between the edges from appearing too narrow or too wide.

Abstract: A method of adjusting color temperature of images displayed by a display system (10) whose images are based on sequential pixel data and are filtered with a color wheel (15, 15', 15"). The relative display times for each color are adjusted to result in a corresponding adjustment of color temperature. In a first embodiment (FIG. 2), the size of the color wheel's segments are changed as well as the display times for data corresponding to each segment. In a second embodiment (FIG. 3), the display times for data corresponding to one or more segments are decreased with a black display time to fill in the difference.
