Abstract:
An actuating device is provided, which includes a deformable membrane, walls formed on the membrane to define cavities, rods formed within the cavities, and on the surface of the membrane on one side with reference to a cavity center, to move in association with the deformation of the membrane, and an actuating unit formed on a lower side of the membrane to be piezoelectrically driven to deform the membrane. The actuating device is applicable to miniaturized electronic devices and can actuate the function modules appropriately.
Abstract:
A motion estimation apparatus and a method considers a correlation between blocks. The motion apparatus includes a full search unit which divides a current frame/field into blocks of predetermined size and estimates an arbitrary motion vector of each block by a full search algorithm; a candidate motion vector estimating unit which computes a plurality of motion prediction error values by applying a block matching algorithm (BMA) to a current block and estimates candidate motion vectors from motion prediction error values below a predetermined threshold; a motion compensating unit which computes a correlation between respective candidate motion vectors and the motion vectors of adjacent blocks and compensates one among the candidate motion vectors to a final motion vector of the current block based on the computed correlation. By estimating motion vector of the current block in consideration of the correlation between the blocks, images free of block artifact can be provided.

Abstract:
A wireless ad-hoc network for transmitting packets to target regions, and a packet transmission method thereof, are provided. The ad-hoc network includes at least one relay node for receiving a packet containing location information of at least two target regions each including at least one node, separating the received packet by the location information, forming a new packet for each instance of the location information separated from the received packet, and forwarding the new packets to corresponding target regions; and a source node for generating the packet containing the location information and transmitting the packet to the relay node. The present invention can reduce the packet transmission overhead, the packet transmission delay, and the power required for the packet transmission. Therefore, the packets can be delivered to the target regions in an efficient manner.
