Latest Patents

One of I-Yen Chen's latest patents is a speed-level calculator and calculating method for dynamic voltage scaling. This invention involves a speed-level calculator that includes a deadline counter, a shifter, and a fixed-point multiplier. The deadline counter calculates the residual time from the current time to each task deadline for completing an episode. The shifter generates a D' value by shifting the D value to the right for e-m bits, taking the decimal fraction part of the D' value for m bits. Additionally, the speed-level calculator features a saturation control circuit to detect any overflow on the D' value. The fixed-point multiplier performs multiplication of D' and a pre-calculated parameter corresponding to each task, ultimately generating a clock period used to switch the processor voltage and frequency.

Another notable patent is a method for aligning gesture features of an image. This method captures an input gesture image and determines a closed curve formed by a binary contour image of the gesture. A curvature scale space image of the gesture is drawn based on the closed curve. A convolution operation is performed to designate the coordinate with the maximal value of integration as a basis point for obtaining a feature parameter of the gesture image. Finally, the feature parameter is compared with those of a plurality of reference gesture shapes to determine the corresponding gesture shape.
