Systems and methods for implementing back-off timing for retries of commands sent from a master device to a slave device over a split-transaction bus. The frame rate improving apparatus determines forward feature point trajectory information through a feature point, and generates a new intermediate frame by performing backward motion estimation through the feature point trajectory information, thereby generating an interpolated image with high quality. Each conductor plate advantageously includes one or more non-conductive regions comprising slots in the transverse direction, and one or more non-conductive regions comprising slots in the longitudinal direction. The received events are processed in accordance with the event parsing logic in the one or more parsing trees.
