To provide a seat weight measuring apparatus having advantages such as reduced production cost and assembling cost. A two-stage redeye filtering system includes a speed optimized filter that performs initial segmentation of candidate redeye regions and optionally applies a speed-optimized set of falsingverification filters to determine a first set of confirmed redeye regions for correction. The dominated nodes A, B and C can execute isochronous transmission without a dominating node equipped with an upper layer for managing the lower layers. A first wire is connected to a first terminal, and the resistance element is coupled to the first terminal.
