Abstract: A power converter having a boosting mechanism with a multi-shaft vertically stepped turbine includes: a shaft sleeve, a water inlet end base, an outer sleeve, a plurality of first stepped turbine units, a plurality of first shaft rods, a plurality of second stepped turbine units, a plurality of second shaft rods and a third shaft rod. The first stepped turbine unit is located above the second stepped turbine unit. The second stepped turbine units and the first stepped turbine units rotate in opposite directions. During a drainage process, water flows move in opposite directions and collide with each other to increase a water pressure. Due to the increase in the water pressure, rotational speeds of the first stepped turbine units and the second stepped turbine units increase, and rotational speeds of the first shaft rods and the second shaft rods correspondingly increase.

Abstract: A visual tracking system helps to detect or locate an active object (such as an active sound source) in a live video or recorded video, and provides a way to help a user who views the live video or recorded video to focus on the active object, without easily being disturbed or distracted by other objects that are present with the active object. The visual tracking system may further track the active object, or detect a new active object when the live video or recorded video is played.
