A device and method for increasing inputoutput from a die by making electrically conductive microvias connecting the integrated circuit with a backside of the die. Then, the video data to be sent are dynamically switched in accordance with motionimage priority instructions entered by a user into a receiving terminal, or changes in the available transmission bandwidth. The locking member includes a lockpin. The pressure of the vacuum is measured by subtracting information detected by the atmospheric pressure variation factor detection units. This process of partitioning data segments into inside child nodes, and outside child nodes is repeated recursively through each level of the ng tree. The openings are configured to restrict movement of the ball by engaging a surface of the ball.
