    摘要: An interactive toy doll is provided having a torso defining a front portion and a back portion. The doll may additionally include legs extending from a lower portion of the torso, an image sensor located on the front portion of the torso, and an image display located on the back portion of the torso. The doll may further include a processor operatively connected to the image sensor and the image display. Additionally, the doll may include legs that may be grasped by a user while leaving the image sensor and the image display exposed so that a user may view an image on the image display while grasping the legs.

    摘要: A digitally-controlled, DC/DC converter includes a switched-mode power stage for the purpose of converting an input voltage (Vin) into an output voltage (Vout); the power stage including a controllable switching device, which is turned ON and OFF by a control device with temporal resolution Δt. The converter further includes a duty cycle control mechanism for controlling the duty cycle of the controllable switching device; the duty cycle control mechanism including a mechanism for estimating the output voltage error, and a selector mechanism for determining the turn OFF and turn ON times of the controllable switching device by choosing, cycle by cycle, an ON time/OFF time pair from a working set of two quantized ON time/OFF time pairs, choosing in such a manner that the amplitude of the output voltage error is continually minimized. At each switching cycle, the current output voltage error estimate is generated, and an ON time/OFF time pair is chosen. Where the output voltage error estimate is small, the choice is determined via a Bresenham sequence generator.

    摘要: A digitally-controlled, DC/DC converter includes at least one switched-mode power stage for the purpose of converting an input voltage (Vin) into an output voltage (Vout); the power stage including at least one controllable switching device, which is turned ON and OFF by a control device with temporal resolution Δt. The converter further includes a duty cycle control mechanism for controlling the duty cycle of the controllable switching device, the duty cycle control mechanism including a mechanism for estimating the output voltage error; a mechanism for estimating the target duty cycle; a duty cycle quantization mechanism for determining, for a target duty cycle estimate, a first set of quantized ON time/OFF time pairs suitable for controlling the switching device; and a selector mechanism for determining the turn ON and turn OFF times of said controllable switching device by choosing, cycle by cycle, an ON time/OFF time pair from a second set of quantized ON time/OFF time pairs, derived from said first set, choosing in such a manner that the amplitude of the output voltage error is continually minimized. At each switching cycle, the current output voltage error estimate is generated, and the ON time/OFF time pair from the second set of quantized ON time/OFF time pairs is chosen, after the switching cycle has begun, but before the turn OFF time implicit in the chosen pair
