An information processing apparatus includes: an image pickup unit, a recognition unit and an execution unit. Water management and reactant distribution may be improved by increasing pressure gradients between adjacent channels. The first calibration module selectively transmits a first set of training signals to the link partner, receives a first set of channel state information for the training signals from the link partner according to the first transmission schedule, and generates a first CSI matrix based on the first set of CSI and the first matrix map. The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. A synthetic jet drives the dry powder from the first chamber to the second chamber.
