  • Patent number: 12127897
    Abstract: The present disclosure relates to a water pumping device for a water flosser, which includes a mounting base, a transmission assembly, a connecting member, and a piston. The transmission assembly includes a first transmission member. The connecting member is disposed in the mounting base in a reciprocally movable manner in a first direction. The first transmission member is rotatable about a first rotation axis perpendicular to the first direction, and in mating connection with the connecting member. The first transmission member is eccentrically disposed with respect to the first rotation axis. During a rotation of the first transmission member about the first rotation axis, the first transmission member reciprocates in the first direction, so as to drive the connecting member to reciprocate in the first direction. The reciprocation of the connecting member in the first direction can drive the piston to reciprocate in the first direction.

  • Patent number: 9621949
    Abstract: A sink apparatus for receiving and playing back multimedia data receives data frames and discards data frames from its processing pipeline in order to reduce latency if it is determined that an amount of media data buffered in one or more portions of the processing pipeline during a fixed playback time period is above a threshold value. The threshold value and therefore the extent to which data frames are discarded can be varied in order to balance latency and quality of the displayed multimedia data.
