Abstract: A DC-DC power converter has an auxiliary tank cascaded to share an efficiency tank's inductor, capacitor, and transformer. Switching transistors pump the auxiliary tank at startup to provide a boost current. The switching frequency is reduced in steps and the voltage gain and power of the converter sensed until the voltage gain matches a voltage gain calculated for the efficiency tank. Then tank switchover occurs and transistors to the efficiency tank are pumped with the last switching frequency used by the auxiliary tank, and the auxiliary tank is not pumped. Since the voltage gains before and after tank switchover are equal, no output voltage deviation or current spike occurs. A voltage sag or failure switches back to the auxiliary tank at a switching frequency determined by a dynamic contour line where the voltage gains of the two tanks are equal for the current power state.

Abstract: The method for assisting a person in operating in a dynamic environment may form part of a mobility assistance system. The method comprises a step of acquiring sensor data comprising a time sequence of at least two consecutive images of the dynamic environment from at least one sensor, for example a camera. Optical flows are calculated based on the at least two consecutive images. Feature scores associated to spatial positions for selected regions in an image space are determined in order to generate a feature score field. An output signal including directional stimulus information is generated based on the generated feature score field, wherein the directional stimulus information comprises information on relative spatial relations between the selected regions. The generated output signal is provided to at least one actuator, which signals the directional stimulus information to the person.
