Described herein is a method and system for motion estimation in a video encoder. There are two parts to the motion estimation. Coarse motion estimation generates a set of motion vectors for a current picture and at least one reference picture. Typically, coarse motion estimation operates on sub-sampled pictures. Fine motion estimation can refine coarse motion estimation results by searching interpolated video data in a region defined by the motion vectors from the coarse motion estimation.

Described herein is a method and system for motion estimation in a video encoder. There are two parts to the motion estimation. Coarse motion estimation generates a set of motion vectors for a current picture and at two or more reference pictures. Fine motion estimation can refine coarse motion estimation results by searching interpolated video data in a region defined by the motion vectors from the coarse motion estimation. Prior to fine motion estimation, the set of motion vectors generated by coarse motion estimation are consolidated in a two level process. In the first level, all motion vectors associated with a particular reference picture are eliminated. For each remaining reference picture in the second level, individual motion vectors are eliminated based on a cost comparison of among motion vectors in a neighborhood.

A dual stage actuated (DSA) suspension includes two PZT microactuators that are attached at their first ends to a non-gimbaled portion of the suspension such as the portion of the flexure that is rigidly attached to the load beam, and are attached at their second ends to the gimbaled portion of the suspension such as the gimbal tongue through flexible connectors that can be formed integrally with the suspension's flexure. The flexible connectors are flexible enough so as not to interfere with the suspension's gimballing action. The flexible connectors transmit force from the PZTs to the gimbal as the PZTs expand and contract in order to rotate the gimbal and thus effect fine movements of the head slider.

A power breaker incudes a fine motion mechanism portion having a chattering suppression portion formed of ring members and a ring member provided with sloping surfaces or curved surfaces at positions corresponding to one another in a state stacked up in a center axis direction, so that an impact generated upon collision of a movable electrode with a fixed electrode when a circuit is closed is trapped as a compression force. Hence, kinetic energy generated upon collision is consumed by energy absorption by friction due to a spring property of the ring members and a frictional force on the contact surfaces. It thus becomes possible to reduce a generation time of a chattering action.
