Abstract: Methods and apparatus to control a three-phase BLDC motor with a curve transformer having an index value for each stored input value and output value for providing stored corner points for outputs of the curve transformer. The curve transformer can output interpolated data for input data between adjacent ones of the input values.

Abstract: Method of predicting capacity demands on a desired device used to support services for a number of subscribers within a market area having a number of devices. The method includes predicting the capacity demands as a function of historical capacity demands for the desired device and average subscriber capacity demands on the number of devices in the market area.

Abstract: Nonlinear compression of high precision image data (e.g., 12-bits per subpixel) conventionally calls for a large sized lookup table (LUT). A smaller sized and tunable circuit that performs compression with piecewise linear compressing segments is disclosed. The piecewise linear data compressing process is organized so that lumping together of plural ‘used’ high precision value points into one corresponding low precision data value point is avoided or at least minimized. In one embodiment, the compressed data is image defining data being processed for display on a nonconventional display screen where the piecewise linearly compressed data can be stored adjacent to other image data in a frame buffer where a composite image is assembled.

Abstract: A direct sampling circuit and a receiver which carry out discrete time analog processing with a high degree of design freedom and are provided with a filter property which is achievable to comply with the receipt of a broad band signal. A plurality of discrete time analog processing circuits (101) are connected in parallel with each other, a gm value and a capacitance of a capacitor in each circuit system are set independently based on a prescribed condition, and an output signal obtained from each circuit system is synthesized by means of a buffer capacitor (102), so that an equivalently high-dimensional IIR filter can be put into practice.

Abstract: A method for deformable registration of 2 digital images includes providing a pair of digital images, including a fixed image and a moving image, extracting a set of edge images from each image of the pair of images, each edge set being extracted at a different resolution, selecting a pair of edge images with a lowest resolution, determining a mapping from edge points of the fixed image to edge points of moving image using a geodesic thin plate spline interpolation, applying the mapping to a next higher resolution edge point image of the moving image, selecting a pair of edge images at a next higher resolution, where a moving edge image is the moving edge image to which the mapping has been applied, repeating the steps at a next higher resolution for all edge images in the set of edge images, and applying the mapping to an entire moving image.

Abstract: According to one embodiment, a first correlation calculator calculates a correlation between first pixel blocks, and detects as first reference pixels actual pixels contained respectively in the first pixel blocks with the highest correlation. A second correlation calculator calculates a correlation between second pixel blocks, and detects as second reference pixels actual pixels contained respectively in the second pixel blocks with the highest correlation. The first pixel blocks include pixels arranged in a plurality of rows and columns The second pixel blocks include pixels arranged in at least one row less than the rows of the first pixel blocks and a plurality of columns. An interpolation calculator calculates, when the first reference pixels are located perpendicular to the actual pixel lines, the pixel value of the interpolation pixel based on the second reference pixels.

Abstract: An image processing device and method for processing an image defined by a combination of unit graphic forms or polygons are provided with an interpolated line completion unit which determines an interpolated line which is the line that interpolates a space between two vertices from an interpolation vector used to determine a line interpolating a space between a given vertex and another vertex among vertices of the unit graphic forms and from the coordinates of those vertices. An interpolated point computation unit is provided which determines as vertices of sub-unit graphic forms or subpolygons into which the polygons are to be split by the processing image device, interpolated points which are the points on the interpolated line. The interpolated line is a Bezier curve.
