摘要： A reference voltage generator circuit may include at least one MOS transistor and at least one bipolar transistor coupled together to provide an electrical path from an input reference potential to an output of the generator circuit. The electrical path may extend through a gate-to-source path of the MOS transistor and further through a base-to-emitter path of the bipolar transistor. The MOS transistor may be biased by a bias current that is proportional to T2·μ(T), where T represents absolute temperature and μ(T) represents mobility of a MOS transistor in the bias current generator. Optionally, the reference voltage generator may include N MOS and M multiple bipolar transistors (N≧1, M≧1), and the output reference voltage may be N*VGS+M*VBE as compared to the input reference potential.

摘要： A detection circuit is coupled to an output terminal of a driver circuit. The detection circuit includes a comparator to compare a signal at the output terminal to a reference signal corresponding to a signal that would be generated if a capacitive load having a relatively high capacitance value were connected to the output terminal. Output of the comparator is sampled at a predetermined time after the driver circuit provides the drive signal. An error signal is generated when the sampled output indicates that the capacitive load having the relatively high capacitance value is actually connected to the output terminal.

摘要： A method and apparatus for converting multi-level raster shapes into bi-level raster shapes while preserving as much of the visual character of the shape is disclosed. The method and apparatus solve two main problems arising in the task: that of broken continuity (drop-outs) and that of large changes in the width of horizontal and vertical lines on the bi-level raster shape as a result of minute changes on the multi-level shape (stem width aliasing). Drop-outs are handled by identifying certain boundaries between pixels as drop-out warnings. Pixels adjacent to dropout warnings have their coverage values converted from multi-level to bi-level by a process that guarantees that at least one of them will be rounded up. Dropout warnings are found from the outline of the ideal shape used to generate the multi-level shape and represent an approximation to said outline. In a preferred embodiment, the set of drop-out warnings for an outline is the set of pixel boundaries containing the nearest pixel boundary to each intersection of the outline with mid-pixel lines. Stem width aliasing occurs because of rounding errors clustering along horizontal and vertical lines. The present invention minimizes stem width aliasing by a variable threshold technique in which the threshold value used to turn the multi-level coverage value of a pixel into a bi-level value depends on the pixel position. The multiple threshold values are used to scatter the rounding errors over neighboring pixels so that they do not cluster along horizontal or vertical lines and are therefore less apparent to a viewer. In a preferred embodiment, two different threshold values are used in a checkerboard pattern, i.e., the threshold value for every other pixel in the horizontal or vertical direction alternates between the two values.

摘要： A method and apparatus is described which fills in the pixels missed when drop-out occurs during the fill process of character contours. The character contour is decomposed into a series of rook moves. The pixel selected is the one more covered by the actual shape of the portion of the curve where the rook moves are coincident and dropout occurs. This is dependent upon the slope of each of the curves at the location of dropout. Preferably the length of the sequence of colinear consecutive rook moves is used to approximate the slopes of the curves. The target pixel of the longest sequence of colinear rook moves is more covered than its opposite pixel and therefore the target pixel is set. The target pixel for a rook move is the pixel in the winding direction (i.e., left or right direction) along the rook move. Thus the target pixel of the stronger rook moves will be set and added to the bit map image generated using a outline fill process. In the preferred embodiment, the rook moves are examined to determine the length of a sequence, that is the number of rook moves that are sequentially in alignment with one another. A strength value is then assigned to each of those rook moves in a sequence equal to the number of rook moves in the sequence. The strength value of the rook move is then compared to the strength value of the opposite pixel, that is the pixel opposite the target pixel for a particular rook move. If the strength value of the target pixel of the rook move is greater than the strength of the opposite pixel, the opposite pixel value if reset to zero and the target pixel is set to equal the strength of the sequence. This process is performed for each rook move in a sequence and for each sequence of rook moves around the contour of the character. Once all rook moves have been evaluated, the value is assigned to the pixels of the character according to this process, are adjusted to reflect a bit map image to be displayed. This is achieved by turning on all bits which are greater than zero. The bit map generated is then logically ORed with the bit map generated using the contour fill process to provide a filled character in which drop out is eliminated and the distortion to the character is minimized.

摘要： An apparatus and method for determining characterizing attributes of an actuator is provided. An actuator may be moved to a maximum capacitance position. At the maximum capacitance position, an initial measurement of the actuator capacitance is made. The actuator is moved a predetermined increment toward a first extreme position, and the actuator capacitance is again measured. If the capacitance changed by a threshold amount, the signal preceding the signal that caused the actuator to move is recorded as an approximate response curve end point, or the first extreme position. The actuator is again moved a predetermined increment toward a second extreme position. After each move, the capacitance is measured. If it is determined the capacitance did change by a threshold amount from the previously measured capacitance, the signal related to the previously measured capacitance is recorded as an approximate response curve end point, or the second extreme position.

摘要： In one aspect of the present invention, a toy arrangement involving a flickering, animated and/or luminescent toy object will be described. The toy arrangement includes a toy object having an ultraviolet sensitive layer. A light source is arranged to illuminate the ultraviolet sensitive layer with ultraviolet light. The ultraviolet sensitive layer is arranged to emit colored light in response to exposure to the ultraviolet light. In some implementations, the light source is arranged to vary the intensity of the ultraviolet light, which in turn can cause the colored light emitted from the toy object to fade, brighten and flicker. The toy arrangement may also include a speaker that emits sounds that are synchronized with changes in the colored light.
